1 Introduction to the GBTS3900 IP

Site

The GBTS3900 IP site is different from the GBTS3900 TDM site. For details about the GBTS3900 TDM site, see its development guide.

1.1 HDLC SiteThe High level Data Link Control (HDLC) site is developed on the basis of the existing GBTS3900 Time Division Multiplexing (TDM) site. An HDLC site does not change a lot in the system architecture and division of subsystems. Only one new feature is added to optimize the transmission through the Abis interface.

Traditionally, the Abis interface works in TDM mode. Each service channel, radio signaling link (RSL), and operation and maintenance link (OML) are separately allocated by 16 K or 64 K sub-timeslot over E1. Even if no service is transmitted over the current service channel, the sub-timeslot allocated to it over E1 is still in use. Other service channels, RSLs, or OMLs cannot use the sub-timeslot. The introduction of the FlexAbis function helps to allocate the transmission resources over the Abis interface for service channels according to service requirements. When the current service channel is idle, the Abis interface does not allocate Abis transmission resources to it. This realizes time-based multiplexing of the Abis transmission resources. The prerequisite of the multiplexing is that some service channels are idle in different cells or sites.

The function of Abis transmission optimization over the Abis interface achieves the multiplexing of transmission resources through HDLC. The function increases the number of transceivers (TRXs) over each E1. Each E1 supports up to 24 TRXs. (There are restrictions: a. full rate voice service; b. The voice active factor is 0.5; c. Cascaded Base Transceiver Stations (BTSs) do not exist over a single E1.) The prerequisite of the multiplexing is that mass mute frames or idle opportunities exist in a service channel. The multiplexing is no more based on some idle service channels. Therefore, the function does not have additional restrictions on services. After Abis transmission is optimized, the transmission resources over E1 or T1, such as single 64 K sub-timeslots, multiple consecutive 64 K sub-timeslots, or multiple nonconsecutive 64 K sub-timeslots are incorporated into an HDLC channel based on the 64 K sub-timeslot through the Abis interface. The OMLs, RSLs, and Transcoding and Rate Adaptation Unit (TRAU) links are multiplexed over the same HDLC. Compared with the TDM resource, the HDLC resource is a shared resource for multiple user flows. When sending and receiving signals over an RSL, OML, or TRAU link, an HDLC site must adapt to



the multiplexing mechanism. In downstream direction, the site needs to obtain its site information from the HDLC channel. In upstream direction, the site needs to share the resource sent through the HDLC channel.

1.2 HDLC HUB SiteDue to existing restrictions on site design, the Abis transmission resources cannot be directly multiplexed across sites. To support the convergence of the Abis transmission resources of multiple sites, a transmission module is introduced to the GTMU.

The cross-site convergence of Abis transmission resources is achieved through the new transmission module. All timeslots of each E1 or T1 between the Base Station Controller (BSC) and the GTMU can be incorporated into a single HDLC channel. The BTSs at the GTMU level and the OMLs, RSLs, and TRAU links of multiple branch BTSs can be multiplexed through the HDLC channel.

The transmission module implements the exchange of upstream packets from the GTMU to the TRX over an OML, RSL, and TRAU. The transmission module also implements the exchange of upstream data to the Abis interface over E1. In addition, the transmission module implements BSC loopback and BTS loopback.

1.3 IP SiteThe IP site is different from the HDLC site. The transmission network between the BSC and the IP site is carried over IP. The control plane and the service plane are carried according to the optimized Abis transmission solution.

Compared with traditional networks, the IP network is competitive in new service support, high bandwidth, and networking costs. The advantages are described as follows:

High performance, such as bandwidths of 100 Mbit/s and 1000 Mbit/s resolving the bottleneck of 2 Mbit/s based transmission, high forwarding capabilities, and high efficiency

Flexible maintenance, such as simple operation and maintenance over IP, flexible routing configuration, and ease of disaster tolerance

Cost effectiveness, such as low costs of network building and maintenance, developed IP technology, time-saving network building

Evolution in line with all-IP networks

Between the BSC and the BTS, the Abis interface uses IP over FE for transmission. The DPTU transmission module implements the exchange of upstream packets from the GTMU to the TRX over an OML, RSL, and TRAU. The transmission module also implements the exchange of upstream packets to the Fast Ethernet (FE). In addition, the transmission module implements BSC loopback and BTS loopback.

In IP transmission mode, the software version supports only the electrical-port communication instead of the optical-port communication and IP over E1.

After obtaining the IP address through DHCP, the IP site automatically learns the gateway address. As only one gateway address can be obtained, you must ensure that all the devices that communicate with the BTS (for example, IPCLK Server) use the gateway address.



2 Networking Modes of IP Site

2.1 Concepts

2.1.1 IP Address and MaskDevice IP: Generally, the IP address identifies only one interface. If a device has multiple interfaces, multiple IP addresses must be configured for the device. For the purpose of clear management, the device IP address is introduced to logically identify a device, for example, BTS. When the BTS communicates with the BSC, the device IP address is used to transmit data.

Port IP: It refers to the IP address of the physical port on the BTS BBU.

Subnet mask: It is a 32-bit numeral corresponding to the IP address. Generally, the more significant bits of the subnet mask are continuous 1s and the less significant bits are continuous 0s. The subnet mask divides the IP address into two parts: subnet IP address and host IP address. In the IP address and subnet mask, the part corresponding to bit 1 is the subnet IP address and the part corresponding to other bits is the host IP address.

To check whether two IP addresses are on the same network segment, AND the two IP addresses with their own subnet masks. If the operation results are the same, the two IP addresses are on the same network segment.

For example:

192.168.1.0/255.255.255.0 is divided into two subnets as follows:

192.168.1.0/255.255.255.128 and 192.168.1.128/255.255.255.128

The 255.255.255.128 subnet mask is a 25-bit mask. The 192.168.1.0 network segment is divided into two subnets, and each subnet has 126 IP addresses.

In practice, to save IP address resources, the customer requires a large subnet mask (for example, 29-bit or 30-bit subnet mask) and about 10 IP addresses on each network segment. Therefore, when configuring IP addresses, you must check whether they are on the same network segment. As a route is required for communication between network segments, the IP communication may fail due to no route configuration.

2.1.2 Route and Routing TableRoute: A router is required for route selection in a network. Based on the destination address of a received packet, the router selects a proper route and transmits the packet to the next router across a network. The last router in the path is responsible for transmitting the packet to the destination host.

Routing table: The routing information is maintained by a routing table. The routing table contains the following key items:



Destination address: It identifies the destination address of an IP packet or the destination network.

Subnet mask: The subnet mask, together with the destination address, identifies the address of the network segment of the destination host or router. That is, the address of the network segment of the destination host or router can be obtained by ADDing the destination address with the subnet mask.

Outgoing port: It refers to the port of the router through which an IP packet is forwarded.

IP address of next hop: It indicates the next router that an IP packet reaches. The address is called a gateway address on the BSC.

2.1.3 DHCP RelayThe BTS obtains an IP address from the BSC through DHCP. A DHCP DISCOVER packet is transmitted in the form of broadcast. In layer 2 networking mode, the BTS can directly obtain an IP address from the BSC. In layer 3 networking mode, the DHCP relay must be configured on the router closest to the BTS.

The DHCP relay can forward DHCP broadcast packets. When the BTS and BSC are not in the same subnet, the DHCP relay can convert broadcast packets from the BTS to unicast packets and transmit them to the BSC over the LAN of the BSC. For configuration details, see 2.2.1 Figure 2-1.

2.2 Recommended Networking ScenariosThis section describes the configurations of port IP addresses on the BSC and BTS sides and provides the active solution and standby solution. In addition, the restrictions on the standby solution are described.

BTS3000V100R008C11 does not support VLAN.



2.2.1 Layer 3 Networking – Active Networking Mode

Active and Standby Ports + VRRP for Two Routers or L3 Switches + Data Network – Active Solution

Figure 2-1 Network topology

Networking description:

The BSC is directly connected to Router A and Router B with FE&GE cables. Router A is a master router, and Router B is a slave router.

The FE/GE interface board of the BSC is FG2a, and the GE port is recommended.

The clock reference source of the BTS can be GPS, IPCLOCK, or MSTP.

One IP clock server supports a maximum of 512 IP sites.

The data network is capable of convergence, and no reconstruction is required.

The number of BTSs in each VLAN should not exceed 50.

There is only one subnet segment in a VLAN.

One or more VLANs are configured on a router port.

VLAN tags are attached by the switching equipment on the access side (the versions later than V100R008C11 support VLAN).

The transmission network between the L3 equipment and BTS requires VLAN, QoS, and DHCP relay. The functions, together with wireless equipment, form a complete solution.

Requirements for the BSS and transmission network

On the BSC side:



Redundancy configuration: The BSC boards work in active/standby mode, and the corresponding ports on the active and standby boards work in active/standby mode. It is recommended that you directly connect the BSC to the routers for L3 networking.

IP address configuration: IP1 is the IP address of the BSC interface that is used to carry services and signaling, and a 29-bit mask is used for the IP address.

Detection mechanism: The ARP detection is enabled on the active port. The gateway IP address to be detected is VRRP Virtual IP and the expiry time is three seconds. If no ARP packet is received successively three times, an alarm is reported. The interface addresses from the active and standby ports to the routers are detected by physical ports.

On the BTS side:

The redundancy mechanism is not used on the BTS side.

The port IP address is recommended.

On the transmission device side:

Router port configuration:

Port1, Port2, Port3, Port4, Port5, and Port6 are configured to work in Portswitch mode and belong to VLAN A. Port2, Port5, Port4, and Port6 are bound to a trunk and Permit all VLAN is configured.

Port7 and Port8 are routing ports and the dynamic routing protocol is enabled.

Detection mechanism: None.

Active and Standby Ports + VRRP for Two Routers + Optical Transmission Equipment





The BSC is accessed to the transmission network through FE&GE. The FE&GE traffic is converged to an OSN across two routers.

The transmission equipment uses EVPLAN for networking.

The interface types used by the BTS include FE.

The clock reference source of the BTS can be line or IPCLOCK.

The VLAN configuration is recommended. VLAN tags are attached by the switching equipment or transmission equipment, and the VLAN is transparent to wireless equipment.

Requirements for the BSS and transmission equipment

On the BSC side:

Redundancy configuration: The BSC boards work in active/standby mode, and the corresponding ports on the active and standby boards work in active/standby mode. It is recommended that you directly connect the BSC to the routers for L3 networking.

IP address configuration: IP1 is the IP address of the BSC interface that is used to carry services and signaling.

Detection mechanism: The ARP detection is enabled on the active port. The gateway IP address to be detected is VRRP Virtual IP and the expiry time is three seconds. If no ARP packet is received successively three times, an alarm is reported. The interface addresses from the active and standby ports to the routers are detected by physical ports.

On the BTS side:




Port configuration: The ports on Router A and Router B are routing ports, and the dynamic routing protocol is enabled between Router A and Router B.

MSTP configuration: The MSTP equipment uses board-level BPS protection.

The router works with the MSTP equipment for BPS switchover. As only one port on the two routers that are connected to the MSTP equipment is UP, one router in VRRP2 is a master router and the other router is an initial router.

Configuration

Figure 2-1 shows the configurations of the port IP addresses and device IP address of the BSC, and a BTS is to be created in the subnet that is separated by multiple routers from the subnet of the BSC.



Figure 2-1 Layer 3 networking model

Figure 2-1 shows a typical layer 3 networking model. The cloud chart indicates multiple subnets. To ensure that Router A can communicate with Router B, do as follows:

Configure the IP address of the BTS as an IP address on the subnet segment of the BTS. If the subnet segment of the BTS is 192.12.12.1/24, you can specify any idle IP address in the range of 192.12.12.1 to 192.12.12.254 to the BTS.

Configure a route on the BSC. The destination IP address is the IP address of the BTS and the next hop is the IP address of port A of Router B. The data sent by the BSC to the BTS can be sent to Router B through the route. Figure 2-2 shows the route configuration on the BSC.



Figure 2-2 Adding a route in layer 3 networking mode

Configure a route on Router B. The destination IP address is the IP address of the BTS and the next hop is the IP address of the equipment (port D) that is connected to port B of Router B. The data sent by the BSC to the BTS can be sent from port B of Router B to the next router through the route. The configuration procedure is as follows:

To add a route (the destination IP address is 192.12.12.1, the mask is a 24-bit mask, and the next hop is 192.12.14.3), run the following command:

[Quidway]ip route-static 192.12.12.1 24 192.12.14.3

To delete a route, run the following command:

[Quidway]undo ip route-static 192.12.12.1 24 192.12.14.3

To query route information, run the following command:

[Quidway]dis ip routing-table

Routing Table: public net

Destination/Mask Protocol Pre Cost Nexthop Interface

192.12.12.1 /24 STATIC 60 0 192.12.14.3 Vlan-interface2

Configure a route on the Router B. The destination IP address is the device IP address of the BSC and the next hop is the port IP address of BSC. The data sent by the BTS to the BSC can be sent from port B of Router B to the BSC through the route. The configuration procedure is the same as the preceding one.

Configure a route on Router A. The destination IP address is the device IP address of the BSC and the next hop is the IP address of the equipment (port C) that is connected to port B of Router A. The data sent by the BTS to the BSC can be sent from port B of Router A to the next router through the route. The configuration procedure is the same as the preceding one.

Configure the DHCP relay on Router A (on the local BTS side). The IP address of the DHCP server is the port IP address of the interface board on the BSC side. The BTS can



obtain IP addresses from the BSC servers in different subnets only after the DHCP relay is configured. The configuration procedure is as follows:

To enable the DHCP service, run the following command:

[Quidway] dhcp enable

To create a DHCP server with group number 1 (the IP address of the DHCP server is 192.19.19.19 (device IP address of the BSC)), run the following command:

[Quidway] dhcp-server 1 ip192.19.19.19

To enter the vlan1 view (port A of Router A belongs to VLAN 1), run the following command:

[Quidway] interface vlan-interface 1

To add VLAN 1 to DHCP server group 1, run the following command:

[Quidway-Vlan-interface1] dhcp-server 1

To query the information on the DHCP server, run the following command:

[Quidway] display dhcp-server all

To query the mapping between the DHCP server and VLAN interfaces, run the following command:

[Quidway] display dhcp-server interface Vlan-interface

2.2.2 Layer 2 Networking – Limited Standby Networking Mode

MSTP Network + Active and Standby Ports + Single Optical Transmission Device – Limited Standby Solution





The two-line bidirectional multiplex section protection ring can be used in MSTP network to improve the reliability.

The FG2a provides the GE optical port for the BSC.

The VLAN configuration is recommended. VLAN tags are attached by the transmission equipment to ports, and the VLAN is transparent to wireless equipment.

The clock reference source of the BTS is a line clock.

Requirements for the BSS and transmission equipment

On the BSC side:

Redundancy configuration: The BSC uses the GE interface boards. The boards work in active/standby mode, and the corresponding ports on the active and standby boards work in active/standby mode (or link aggregation can be used to provide higher reliability).

IP address configuration: IP1 is the IP address of the BSC interface that is used to carry services and signaling.

Detection mechanism: physical detection.

On the BTS side:




The MSTP equipment uses the GE (HUAWEI OSN: EMS4) interface board, and the port PPS protection is configured.

The transmission network is a ring network that provides higher reliability.

When the port on the OSN is deactivated, the active and standby ports are simultaneously deactivated. In this case, the transmission is disconnected. Therefore, you cannot deactivate the port.

Configuration

Figure 2-1 shows the configurations of the port IP addresses and device IP address of the BSC, and a BTS is to be created in the subnet of the BSC.



Figure 2-1 Layer 2 networking model

Figure 2-1 shows a typical layer 2 networking model. The dashed line indicates that there are one or more switches between Switch A and Switch B. To ensure that Switch A can communicate with Switch B, do as follows:

Configure the IP address of the BTS as an IP address on the subnet segment of the port IP address of the BSC. As the port IP address of the BSC is 192.12.15.1/24, you can specify any idle IP address in the range of 192.12.15.1 to 192.12.15.254 to the BTS.



2.2.3 MSTP Application Scenarios

Scenario 1: EVPL – Limited Standby Solution


Advantages:

A VLAN is configured for each BTS. As the VLANs are used to distinguish BTSs and paths, the network structure is clear, the configuration is simple, and the internal faults can be located easily.

On the BTS side, the transmission equipment divides VLANs for wireless services by ports. On the BSC side, VLAN tags are attached for services by BTSs.

The VLAN isolation ensures network security and no broadcast storm occurs.

Disadvantages:



Too many VLANs are required. If independent VLANs are configured for the OM, the consumption of VLAN resources is larger. In addition, the BSC is required to have higher VLAN capability.

The VLAN ID must be unique. If the VLANs are reused between regions, the planning and configuration are very difficult.

When the wireless side and transmission side are based on VLAN tight coupling, an error easily occurs, the flexibility is poor, and the expansion and adjustment in the future are very difficult.

Scenario 2: EVPLAN


Advantages:



As the MAC address switching is used, the VLAN quantity is reduced. In this case, the site launching and swapping are easier and the speed is quicker.

It is unnecessary to set up an end-to-end unique VLAN channel for each BTS. In this case, manual configuration errors in the wireless and MSTP networks can be reduced.

Disadvantages:

When a packet is forwarded on the basis of the MAC address in the MSTP network, the problem location and the maintenance are difficult.

To prevent the port loopback from affecting services, you need to disable the loopback on any port (including Ethernet port and VCTRUNK optical cable) or upgrade the MSTP network to support the Ethernet OAM feature that automatically blocks the port loopback.

The EVPLAN solution is recommended to save VLAN resources and reduce the configuration complexity. The networking details are as follows:

MSTP uses 2-level convergence, and the EVPLAN solution is used for both level 1 and level 2. EGS4 is mapped on the basis of MAC and VC.

The OSN and CE use the BPS+VRRP networking mode. To prevent the network storm and identify the L2 priority, you are advised to assign one VLAN ID to a maximum of 50 BTSs under a BSC.

The Ethernet port of the transmission equipment at the access layer is configured to work in Hybrid mode for commissioning before site launching.

You are advised to configure one VLAN for the BTSs under two pairs of EGS4s in the level 1 convergence (in the level 1 convergence, a pair of EGS4s support a maximum of 64 BTSs). The IP addresses are planned on the same network segment so that the CE attaches VLAN tags based on the IP addresses.

In the level 2 convergence, one BSC is configured with a pair of EGS4s. In phase 1, each pair of boards are configured with a pair of GE ports. For the later expansion, two pairs of GE ports are configured.

The VLAN tags of downlink services on the BSC side are attached by the layer 3 equipment based on the destination IP address, and the VLAN tags of uplink services on the BTS side are attached by the transmission equipment based on ports.

2.2.4 PTN EquipmentThe PTN is a new generation metropolitan fiber transmission platform which adopts the packet transmission mode.

The emerging application of data services has an increasing demand on the bandwidth, and poses higher and higher requirements for the flexibility of the bandwidth adjustment.

As a traditional circuit switched network, the multiple service transmission network, which is based on the SDH, can hardly meet the requirements of the unexpected and flexible data services.

In traditional connectionless IP network, the quality and performance of the important services can not be ensured. Therefore, the traditional connectionless IP network cannot serve as the carrier-class bearer network.

The PTN applies the PWE3 (Pseudo Wire Emulation Edge-to-Edge) technology to carry the connection-oriented services. To optimize the carrier-class bearer network, the PTN uses the Multiprotocol Label Switching (MPLS) technology together with the comprehensive Operation, Administration and Maintenance (OAM) functions and the switching protection



mechanism. As a combination of advantages of the packet transmission network and SDH transmission network, the PTN achieves to provide the carrier-class services.

Clock

The clock synchronization solution of the GSM IP BSS is related to the networking solution. The actual network involves the following clock modes:

IP clock: The IP clock server is connected to support a maximum of 512 clients.

Trace transport clock: The E1 line is connected.

External synchronization clock: The clock source is connected.

Trace GPS clock: The DGPS of the BSC is connected.

2.2.5 Setting the Clock Mode of a SiteYou can set the clock mode by one of the following two methods:

Method 1

Step 1 Right-click the GTMU of the BTS whose clock mode is to be changed, and then choose Maintain Clock from the shortcut menu. In the Maintain Clock dialog box, right-click the attribute list, and then choose Set Clock from the shortcut menu, as shown in Figure 2-1.



Figure 2-1 Maintain Clock dialog box

Step 2 In the Set Clock Information dialog box, select Clock Mode and Trace Mode, and then click Set, as shown in Figure 2-1.



Figure 2-1 Set Clock Information dialog box

The clock modes are explained as follows:

Internal clock: The BTS does not trace the external clock, and the internal high-precision clock works in free-run mode.

External synchronization clock: The internal high-precision clock of the BTS traces the external synchronization clock signals.

IP clock: The BTS synchronizes the clock with the IP clock server through the IP network.

Trace transport clock: If the E1 transmission mode is upgraded to the IP transmission mode and no IP clock is available, the BTS can extract the clock through the E1 line on the transmission network.

Trace GPS clock: The BTS extracts and synchronizes the clock from the GPS through the DGPS.

Trace BSC clock: The internal high-precision clock signals of the BTS trace the clock signals from the BSC.

The differences between the transmission modes are as follows:

If the IP transmission mode is used, Trace Transport Clock can be configured and Trace BSC Clock cannot be configured.

If the non-IP transmission mode is used, Trace BSC Clock can be configured and Trace Transport Clock cannot be configured.

The BTS obtains the clock signals from the E1 port regardless of whether Trace BSC Clock or Trace Transport Clock is configured.

When Trace BSC Clock is configured, you do not need to configure the E1 port from which the clock signals are obtained.

When Trace Transport Clock is configured, you need to configure the E1 port from which the clock signals are obtained.



The trace modes are explained as follows:

If Disable Trace Range Limit is selected, the BTS always traces the upper-level reference clock.

If Enable Trace Range Limit is selected and |f| 2 Hz, the reference clock is traced. If Enable Trace Range Limit is selected and |f| > 2 Hz, the internal clock works in free-run mode and the reference clock is not traced.

----End

Method 2

Step 1 On the LMT, right-click the target site in the navigation tree on the left, and then choose Site Operation > Configure Site Attributes from the shortcut menu. In the Site Attributes dialog box, click the Basic Information tab, and then change the setting of Reference Clock Source Type, as shown in Figure 2-1.

Figure 2-1 Site Attributes dialog box



Both method 1 and method 2 can be used to set the clock mode of the BTS. If method 2 is used, you can also change the setting of Clock Mode as described in method 1. See Figure 2-1. If method 1 is used, the setting of Reference Clock Source Type cannot be changed as described in method 2. Thus, if the settings of the two parameters are inconsistent, the setting of Clock Mode is valid.

If the offset of the DA calibration value is high during the deployment, the lock time of the clock is long. In this case, you need to adjust the DA calibration value on the LMT.

Step 2 Right-click the GTMU of the BTS whose DA value is to be changed, and then choose Maintain Clock from the shortcut menu.

Step 3 In the Maintain Clock dialog box, right-click the attribute list, and then choose Set Clock from the shortcut menu.

Step 4 Select Set Calibration Value in the Set Clock Information dialog box, as shown in Figure 2-1.

Figure 2-1 Set Clock Information dialog box

2.2.6 Configuring the IP Clock ServerThe IP clock server can work with the IP site to provide the standard clock reference source.



Configuring the Clock Server

The contents to be configured include the working mode of the clock server, the type of the client connected to the clock server, system time, clock source mode, clock source, DA value, and route between the clock server and the BTS. For details, see the related clock server document. Figure 2-1 shows the position of the clock server in a network.

Figure 2-1 Position of the clock server in a network

Configuring the Clock on the BSC LMT

Note: You can skip this procedure if the IP clock is already configured.

Step 1 On the BSC6000 LMT, right-click BSC6000 in the navigation tree on the left, and then choose Configure BSC Attributes from the shortcut menu.

Step 2 Click the IP Transfers tab in the Configure BSC Attributes dialog box, and then configure Clock Server IP, ShakeHandPeriodA, ShakeHandPeriodB, ShakeHandPeriodC, and Clock synchronization Mode. In the case of the intermittent synchronization mode, you need also configure Interval Synchronization Period(Day), Interval Synchronization Start Time(Hour), and Interval Synchronization Start Time(Minute). Click Finish, as shown in Figure 2-1.



Figure 2-1 Configuring the clock on the BSC6000 LMT

----End

1.To ensure that the clock frequency output by the clock server is a standard reference source, you must calibrate the clock server before using it.

2.The value of ShakeHandPeriodB must be greater than the values of ShakeHandPeriodA and ShakeHandPeriodC.

Figure 3-1 Add New Site dialog box



The following describes the meanings of the parameters in the Add New Site dialog box.

Ring Mode: The value of this parameter is either YES or NO. YES indicates that the cascading of BTSs is supported and the ring network is established. Thus, if any BTS in the cascaded BTSs is disconnected, all the other BTSs can still communicate with the BSC properly. Abis By Pass Mode cannot be set regardless of whether Ring Mode is set.

Step 4 Return to the Add Site dialog box and click Next. In the Add Cell dialog box, click Add Cell, as shown in Figure 3-1.

3.2.2 Configuring Hardware and the Transmission Network

Selecting the Port Corresponding to the GEHUB Board

Select the E1 line led out through the port that corresponds to the GEHUB board specified in 3.2.1 "Adding an HDLC Site on the BSC6000 LMT." The numbering of E1 lines starts with 1 whereas the numbering of port numbers starts with 0. Therefore, you can select an E1 line based on a port number plus 1. For example, in 3.2.1 "Adding an HDLC Site on the BSC6000 LMT", the number of the upper-level port is 3. Therefore, you should select #4 E1 line led out from the GEHUB board.

When you connect the E1 line between the BSC and the site, ensure that the sending end of the BSC connects to the receiving end of the site and the receiving end of the BSC connects to the sending end of the site. On the E1 line, the sending end is marked with TX, and the receiving end is marked with RX.

Configuring the Transmission Network

Ensure that the E1 line is properly connected from the port of the site to the port of the BSC. You can use E1 line loopback to check whether the line is physically connected.

Powering On and Checking Status

Check whether the status of the RUN LED on the GTMU board in the common subrack is normal (on for one second and off for one second).

Check whether the status of the LIU LED is off.



For details about the LEDs on the TMU panel, see 6.1 "LEDs on the TMU Board."

3.2.3 Upgrading a TDM Site on the Existing Network to an HDLC Site

Generally, the TDM site is configured on the GEIUB of the BSC rack. To upgrade a TDM site to an HDLC site, you must ensure that the GEHUB is available on the BSC side. If no GEHUB is available on the BSC rack, you need to insert the board and then complete the configuration.

You can upgrade a TDM site on the existing network to an HDLC site by one of the following two methods: 1. Upgrade a TDM site on the existing network to an HDLC site by the site movement function; 2. Directly build an HDLC site.

Method 1: Upgrade a TDM site on the existing network to an HDLC site by the site movement function (method 1 is recommended to facilitate the construction and reduce the service interruption time)

Step 1 Select the GEHUB of the BSC corresponding to the target HDLC site and the available port of the GEHUB.

Step 2 To move a site, do as follows:

On the BSC6000 LMT, right-click the TDM site to be upgraded in the navigation tree, and then choose Site Operation > Move Site from the shortcut menu, as shown in Figure 3-1.

Click Continue, as shown in Figure 3-7. After the timeslots in the TDM site are arranged, a message is displayed to prompt you to confirm the operation. Then, click OK.


Step 3 Remove the E1 cable that connects the TDM site to the GEIUB. Then, insert the E1 cable into the GEHUB in the BSC rack. (Remove the original E1 cable that connects the TDM site to the GEIUB in the BSC rack, and then insert the cable into the corresponding port on the GEHUB that is connected to the added HDLC site.) The OML is established after two minutes and the RSL is established after five minutes.

Step 4 After the previous operations, the site still runs properly. The services processed on the site are disrupted for about 15 minutes during the entire process.

----End

Method 2: Upgrade a TDM site on the existing network to an HDLC site by directly building an HDLC site

If the existing TDM site is attached to the GEIUB board, you can perform the following operations on the BSC LMT:Configuring an HDLC Site (For details, see 3.2.1 "Adding an HDLC Site on the BSC6000 LMT.") > Preparing the E1 Line from the BSC to the Site > Loading the Latest Version of the TMU > Disconnecting the Existing Network Cable from the TDM Site and Inserting the E1 Line into the Subrack > Activating the TMU Version > Loading the Latest Version of the TRX > Activating the TRX Version

Step 3 To complete the configuration of the lower-level site to the HDLC HUB site after the site is moved, you need add the lower-level site by referring to 3.3.1 "Adding an HDLC HUB Site on the BSC6000 LMT" after moving the BTS.

Step 4 Remove the E1 cable that connects the TDM site to the GEIUB. Then, insert the E1 cable into the GEHUB in the BSC rack. (Remove the original E1 cable that connects the TDM site to the GEIUB in the BSC rack, and then insert the cable into the corresponding port on the GEHUB that is connected to the added HDLC site.) The OML is established after two minutes and the RSL is established after five minutes.

Step 5 After the previous operations, the site still runs properly. The services processed on the site are disrupted for about 18 to 20 minutes during the entire process.

----End

Method 2: Upgrade a TDM site on the existing network to an HDLC HUB site by directly building an HDLC HUB site

To reduce the time of service interruption, you can upgrade a TDM site to an HDLC HUB site as follows:Configuring an HDLC HUB Site on the BSC6000 LMT > Preparing the E1 Line from the BSC to the Site > Loading the Latest Version of the TMU > Loading the Latest Version of the TRX > Activating the Latest Version of the TMU (Supporting the PTU) > Disconnecting the Existing Network Cable from the TDM Site and Inserting the E1 Line into the Subrack

The operations for configuring the HDLC HUB site on the BSC6000 LMT are the same as those for adding an HDLC HUB site. For details, see 3.3.1 "Adding an HDLC HUB Site on the BSC6000 LMT."

The operations for configuring hardware and the transmission network are the same as those for adding an HDLC HUB site. For details, see 3.3.1 "Adding an HDLC HUB Site on the BSC6000 LMT."



3.4 Adding an IP SiteTo support an IP site, you need to add the GFGUB (an IP Abis interface board) on the BSC6000. For details, see the related BSC6000 deployment guide.

This topic describes how to add an IP site. This procedure consists of the following operations:Adding an IP Site on the BSC6000 LMT > Installing the BBU > Adding a Physical Connection Between the Site and the BSC > Configuring the Transmission Network > Powering On and Checking Status > Loading and Upgrading Software

The BSC provides the port IP address and the device IP address for communication with the BTS. Table 3-1 lists the comparison between the two communication modes. For details, see the related BSC6000 deployment guide.

Table 3-1 Comparison between the port IP address and the device IP address

Port IP Address Device IP Address

Advantage 1. The configuration is simple.

2. The port IP address is visible to the intermediate transmission network.

3. When the port IP address serves as a service IP address, fewer addresses are required.

When a physical link is faulty, the communication mode is simpler to implement mutual aid between links and ensure that services are not affected.

Disadvantage When a physical link is faulty, the communication mode is more complex to implement mutual aid between links and ensure that services are not affected.

1. A static route to the device IP address must be configured.

2. When the L3 transmission equipment exists between the BTS and the BSC, the route to the device IP address must be known. In this case, the requirements for the transmission network are high.

3. When the device IP address serves as a service IP address, more addresses are required.

3.4.1 Obtaining the Bar Code of a SiteThe bar code uniquely identifies a site in the BSC. Before adding an IP site, you need to obtain the bar code of the site. The bar code is marked in three places of the BBU subrack, as shown in the yellow areas in Figure 3-1 (another place is the bottom of the subrack). The bar code of the BBU subrack is the bar code of the site (20 bits), as shown in the red area in Figure 3-2.

If the bar code is configured improperly on the BSC, the BTS cannot obtain an IP address through DHCP. During the deployment, you must ensure that the bar code of the BBU is consistent with that configured on the BSC.

When the BSC6000 communicates with the BTS through the device IP address or the port IP address, the configurations on the BTS side are the same.

When the active and standby GFGUBs are used, a switch must be configured between the BSC and BTS (that is, the ports with the same number on the active and standby GFGUBs are connected to the switch). Generally, the data configuration is performed for the active board, and the BSC automatically backs up the data to the standby board.

Step 1 Configure the device IP address (skip this step if you have set the device IP address of the BSC). On the BSC6000 LMT, right-click a GFGUB board and choose Configure Device IP, as shown in Figure 3-1.

Figure 3-1 Setting the device IP address

In the Configure Device IP dialog box, click Add. Set the logical IP address and the subnet mask. Then, click OK, as shown in Figure 3-2.



Figure 3-2 Adding a device IP address

Step 2 Set port IP addresses. On the BSC6000 LMT, right-click a GFGUB board and choose Configure Ethernet Port Ip, as shown in Figure 3-1.

Figure 3-3 Setting the IP address for port 5



Step 3 Configure the router between the BSC and the BTS. For layer 2 networking, skip this step. On the BSC6000 LMT, right-click the GFGUB board and choose Configure BSC router, as shown in Figure 3-1.

Figure 3-1 Configuring a BSC router

The Configure BSC router dialog box is displayed, as shown in Figure 3-2.



Figure 3-2 BSC router

In the Configure BSC Router dialog box, click Add to add a BSC router, as shown in Figure3-3.

Figure 3-3 Adding a BSC router

The destination IP address of the route is the network segment where the IP address of the BTS is located. The next hop is the IP address of the port of the router that is connected to the



BSC. The DHCP relay is configured on the router that is connected to the BTS and not configured on the port of the BSC.

In layer 3 networking, the IP address and the subnet mask of the site should be changed to the IP address and the subnet mask of the corresponding destination network segment.

Step 4 On the BSC6000 LMT, right-click a GFHUB and choose Add Site from the shortcut menu, as shown in Figure 3-1.






Step 6 In the Add New Site dialog box, set the parameters as required. Set Site Type to BTS3900 GSM to Service Mode to IP. Then, click OK to finish the configuration, as shown in Figure 3-1.


2.The Cfg RFU by Slot check box is not selected when adding a new site. The future configuration could be based on the RXU topological structure (for details, see Step 9).




The following describes the meanings of the parameters in the Add New Site dialog box.

Site IP and IP Mask: Currently, the BTS can communicate with the BSC through the IP network. Therefore, Site IP and IP Mask should be set. In layer 2 networking mode, the IP address of the BTS should be on the same network segment as that of port 5 on the BSC.

Step 7 In the Add Site dialog box, click Next. In the Add Cell dialog box, click Add Cell, as shown in Figure 3-1.



The IP sites cannot be cascaded.


In the Add New Cell dialog box, set Cell Name and Frequency Band. Then click OK to finish the configuration, as shown in Figure 3-2.


Step 8 Return to the Add Site dialog box, and then click Next. In the Configure Site Attributes dialog box, click Site Attributes, as shown in Figure 3-1.




Step 9 In the Site Device Attributes dialog box, right-click the icon under RXU topological structure. Choose Add RXU Chain from the shortcut menu, as shown in Figure 3-1.


In the Add RXU Chain dialog box, set Chain Type and Chain Head Board Port. Chain Head Board Port is the port number of the SFP where the TRX is connected, that is, the CPRI port; Chain Type can be Chain or Ring depending on actual scenarios. The chain or ring here indicates the topological structure of the TRX. Then, click OK. Figure 3-2 takes adding a chain on SFP 0 of the GTMU as an example.









Figure 3-1 Adding the GRFU

In the Add GRFU dialog box, set RXU NAME and RXU No., as shown in Figure 3-2. Then, click OK.






In the Binding logical TRX dialog box, select Trx No. and set Assigned Cell.






Step 12 Right-click the added chain, and then choose Configure RXU Attribute from the shortcut menu to set board attributes as planned, as shown in Figure 3-1.




Step 13 If a new site board is to be cascaded with the GRFU, right-click the GRFU, and then choose Add RXU > Add GRFU from the shortcut menu, as shown in Figure 3-1.




To add a board over a different port, repeat Step 9 through Step 13. In RXU topological structure, add all required RXU boards and logical TRXs. When you add cells in batches, ensure that each cell is configured with at least one carrier.

Step 14 In the Site Device Attributes dialog box, right-click a GTMU board and choose Configure Board Attributes, as shown in Figure 3-1.

3.4.3 Configuring the IP Clock ServerThe IP clock server can work with the IP site to provide the standard clock reference source.

Configuring the Clock Server

The contents to be configured include the working mode of the clock server, the type of the client connected to the clock server, system time, clock source mode, clock source, DA value, and route between the clock server and the BTS. For details, see the related clock server document. Figure 3-1 shows the position of the clock server in a network.



Figure 3-1 Position of the clock server in a network

Configuring the Clock on the BSC6000 LMT

Note: You can skip this procedure if the IP clock is already configured.

Step 1 On the BSC6000 LMT, right-click BSC6000 in the navigation tree on the left, and then choose Configure BSC Attributes from the shortcut menu.

Step 2 Click the IP Transfers tab in the Configure BSC Attributes dialog box, and then configure Clock Server IP, ShakeHandPeriodA, ShakeHandPeriodB, ShakeHandPeriodC, and Clock synchronization Mode. In the case of the intermittent synchronization mode, you need also configure Interval Synchronization Period(Day), Interval Synchronization Start Time(Hour), and Interval Synchronization Start Time(Minute). Click Finish, as shown in Figure 3-1.



Figure 3-1 Configuring the clock on the BSC6000 LMT

----End

1.To ensure that the clock frequency output by the clock server is a standard reference source, you must calibrate the clock server before using it.

2.The value of ShakeHandPeriodB must be greater than the values of ShakeHandPeriodA and ShakeHandPeriodC.



Select the E1 line led out through the port that corresponds to the GFGUB board specified in 3.4.2 "Adding an IP Site on the BSC6000 LMT." The new site is set up over a port. Ensure that you connect the network cable from the specific port to the site. For example, in 3.4.2 "Adding an IP Site on the BSC6000 LMT", the new IP site is attached to the GFGUB board in



slot 20 and uses #5 upper-level port. (The numbering of ports starts with 0.) Therefore, you should connect the sixth port of the GFGUB board from top down to the port of the IP site.


Ensure that the connection is normal from the port of the site to the port of the BSC.

You can use the following method to test the connectivity:Step 1 Connect the network cable from the FE0 port of the TMU board to a PC.Step 2 Change the IP address of the PC to the address set for the FE0 port of the TMU board.Step 3 On the PC, run the ping command to ping the physical IP address of the GFGUB board corresponding to the BSC.If the ping is successful, it indicates that the physical connection is normal. Otherwise, check the network cable. You can use the same method to test the FE1 port.

The details are as follows:

Figure 3-1 Ping connection

Check the continuity between the BSC and the BTS when the optical interface board of the BSC is used.

The optical signals from the optical interface board of the BSC can be accessed to the optical transmission network of the customer in two modes: direct access or access through optical switching. As the BTS3900 does not support an optical transmission connection currently, there must be an optical and electrical switch on the BTS side.

To check whether the transmission link is normal, do as follows:(1) Connect a PC to the switch that is accessed by the BTS.(2) Ping the interface board of the BSC.(3) Ping the PC on the BSC.If the preceding ping operations are successful, it indicates that two interfaces of the BSC and the BTS on the transmission network can communicate with each other. If a link cannot be set up on the site, you need to check the BSC configuration, physical connections of the BTS, and board status. You can capture packets on the switch on the BTS side and feed them back to the R&D personnel for analysis.



If the ping operations are failed, you can add a switch on the BSC side and connect a PC to the switch. Then, ping the PCs on the BTS side and the BSC side. If the ping operation is successful, you need to check the physical connections of the BSC. If the ping operation is still failed, you can request the network engineer of the customer to check whether the transmission network properly allocates resources.

Check the continuity between the BSC and the BTS when the electrical interface board of the BSC is used.

The check method is basically the same as that for the optical transmission.

Note: If the transmission network is abnormal, an optical and electrical switch may be required so that a PC is connected to the switch for pinging and packet capturing.

The transmission network is very complex and may contain NEs of multiple vendors. Currently, there is no effective and accurate location method for a transmission link fault. In practice, if the transmission link is faulty, you can only perform loopback tests for the entire transmission network section by section to find faulty nodes.

3.4.5 Upgrading a TDM Site on the Existing Network to an IP Site

Generally, the TDM site is configured on the GEIUB of the BSC rack. To upgrade a TDM site to an IP site, you must ensure that the GFGUB is available on the BSC side. If no GFGUB is available on the BSC rack, you need to insert the board and then complete the configuration. You can upgrade a TDM site on the existing network to an IP site by one of the following two methods: 1. Upgrade a TDM site on the existing network to an IP site by the site movement function; 2. Directly build an IP site.

When the TDM site works normally, you can run the DSP ELABLE command (with the subrack number set to 0 and the slot number set to 23) to obtain the bar code of the BTS.

DSP ELABEL: DEVTYPE=BTSBRD, IDXTYPE=BYIDX, BTSIDX=73, SRN=0, SN=23;

The IP functions of the BTS3900 are supported in V100R008 and later versions. If the current version does not support the IP functions, you must upgrade the current version to the version that supports the IP functions in TDM mode.

If the BSC corresponding to the TDM site and the BSC corresponding to the target IP site are located in different places, method 1 cannot be used because that different BSC racks are involved. In this case, only method 2 can be used.

Generally, the BTS and BSC are placed in different places. For convenient construction, the upgrade procedure consists of the operations on the BTS side and those on the BSC side. The operations on the BTS side are mainly to connect network cables. The operations on the BSC side are to upgrade the software version of the BTS on the BSC6000 LMT, configure the BSC GFGUB and corresponding ports, and move the BTS on the BSC6000 LMT.

If an external PCU is configured for GPRS services in a cell under the TDM site, you must disable the GPRS services under the site. Otherwise, the configuration for site movement fails.

Method 1: Upgrade a TDM site on the existing network to an IP site by the site movement function

Step 1 Select the GFGUB of the BSC corresponding to the target IP site and the available port of the GFGUB, and then configure related IP addresses for the BSC. For details, see Step 1 through Step 3 in 3.4.2 "Adding an IP Site on the BSC6000 LMT."

Step 2 Connect the transmission cable between the BSC and the BTS (for details, see 3.4.4 "Configuring Hardware and the Transmission Network").



Step 3 Right-click the TDM site to be upgraded and choose Site Operation > Configure Site Attributes from the shortcut menu. Then, set CRC4 Check Switch to ON on the Basic Information tab page in the displayed Site Attributes dialog box, as shown in Figure 3-1.

Figure 3-1 Setting the CRC4 check switch

Step 4 Deactivate the TDM site (optional). Right-click the TDM site to be upgraded and choose Site Operation > Set Site Active State from the shortcut menu. Then, set Site Active State to Not Activated.

After the TDM site is deactivated, the operations in Step 6 cannot be performed because that the operation time of the IP site is long.



Step 5 Delete the monitoring timeslots of the site.

Right-click the TDM site to be upgraded, and then choose Configure Site Monitor Timeslot from the shortcut menu. In the Configure Site Monitor Timeslot dialog box, delete all the monitoring timeslots.

Step 6 Reset the site so that the site works in probe state to reduce the interruption duration (optional).


Note: You must delete the monitoring timeslots before moving a site.









In the Move Site dialog box, select IP to change the TDM site to the IP site, as shown in Figure 3-3.Click BSC Port. In the displayed dialog box, click YES. The Choice Board&Port dialog box is displayed, as shown in Figure 3-4.





Set the parameters Dest SubRack No., Dest Slot No., and Dest Port No. to proper values based on the GFGUB position. Then, click OK.

In the displayed dialog box, click OK to return to the Move Site dialog box, and then click Next, as shown in Figure 3-5.

The bar code of the BBU and the IP information of the site are not configured when the site is moved. In this case, a dialog box is displayed, prompting you to confirm the settings. You can click OK to ignore this message. (The attributes of the BBU are separately configured after the site is moved.)










Step 8 Configure the parameters of the GTMU.

The configuration contents include the attributes of the board (for details, see Step 14 in 3.4.2 "Adding an IP Site on the BSC6000 LMT"), bar code of the BBU, IP address information of the BTS (IP address and subnet mask of the BTS), and FE port parameters of the BTS.

Step 9 Activate the IP site (optional).

Set Site Active State to Activated (for details, see Step 4).

Step 10 Check the operation status of the site 20 minutes after the operations are complete.

----End

Method 2: Upgrade a TDM site on the existing network to an IP site by directly building an IP site

Step 1 Select the GFGUB of the BSC corresponding to the target IP site and the available port of the GFGUB, and then configure related IP addresses for the BSC. For details, see Step 1 through Step 3 in 3.4.2 "Adding an IP Site on the BSC6000 LMT."

Step 2 Connect the transmission cable between the BSC and the BTS (for details, see 3.4.4 "Configuring Hardware and the Transmission Network").

Step 3 Configure the IP site on the BSC LMT (for details, see 3.4.2 "Adding an IP Site on the BSC6000 LMT").

Step 4 Check the operation status of the site 20 minutes after the operations are complete.

----End



3.4.6 Switching an IP Site Back to a TDM SiteIf a TDM site is upgraded to an IP site by building the IP site, the procedure for switching an IP site back to a TDM site is as follows: Remove the network cable, restore the original connections of the TDM site, and then wait for the reset of the site.

If a TDM site is upgraded to an IP site by the site movement function, the procedure for switching an IP site back to a TDM site is as follows:

Step 1 Remove the network cable from the BSC, and then restore the original connections of the TDM site.

Step 2 Right-click the TDM site to be upgraded and choose Site Operation > Configure Site Attributes from the shortcut menu. Then, set CRC4 Check Switch to OFF on the Basic Information tab page in the displayed Site Attributes dialog box, as shown in Figure 3-1.
