Required Layer 3 Routing Protocols (IPv4):

Network protocols: TCP/IP stack, ARP, DHCP relay

IP Routing: OSPF v2

Redundancy: VRRP v2.

BSS Architecture

IPoEth BSS Architecture

In this configuration, there is IPoEth on Abis and Ater.

9130 BSC, TC, 9130 MFS are connected through the IP network of the operator.

The CS user plane is passed directly to the TC over IP, while the CS control plane is

directed towards the BSC.

This is show in the following figure.

IPoE1 BSS Architecture

In this configuration, there is IPoE1 on Abis and IPoEth on Ater.

It is an intermediate step towards a full IPoEth network solution: 9130 BSC, TC, 9130

MFS and 9153 OMC-R are connected through the IP network of the operator.

However, BTS are still connected through E1 links.

17/104

This mode preserves the existing E1 links on the Abis interface and introduces IP

transport using the Point-to-Point Protocol (PPP) or the Multi Link Point-to-Point

Protocol (ML-PPP) in the case of more than one E1 link.

Those protocols are used to encapsulate the IP traffic within HDLC frames, which are

then sent over the E1 links. In this mode, all traffic is routed towards the BSC.

The following figure shows the BSS with IPoE1 on Abis (and IP backbone on Ater).

(1): Due to the mixed mode, some E1 links in Atermux are kept until all BTS have

switched to IP mode. This must be taken into account in order to ensure IP to TDM comeback mechanisms inside the TC (in the case of failure of one TC board).

(2): This link allows to transmit some part (or the totality) of the Gb traffic through a set

of TS of the A interface E1 links. This traffic is cross connected through the MFS, the TC

and the MSC towards the SGSN (note that the MSC-SGSN link is not the Gs interface). It

is called the "Gb insertion" mode and is only possible if CS and PS traffic share the same

Ater-mux E1 link. This mode is not supported in IP transport mode (this would be needed

only for the few BTSs which remain in TDM mode in mixed mode, we assume that the

operator will switch to IP the major part of its BTSs; moreover, the GboIP feature is

available). In this particular case, going to IP mode will require the operator to add a new

E1 link on Gb.

Mixed Mode BSS Architecture

This mode allows the BSS to handle at the same time some BTS in TDM mode (for B10)

and others in IP mode (IPoE1 or IPoEth).

1-3


18/104

This mode allows the BSS to handle at the same time some BTS in TDM mode (for B10)

and others in IP mode (IPoEth).

It provides the operator with a "step by step" introduction of IP in the network.

Layer 2 BSS Architecture

Using a Layer 2 transport network means that, despite the fact that the BSS NEs (BTS,

BSC, TC, MFS) will still exchange IP packets, the underlying functional architecture of

the transport network can be seen as a single LAN (in practice, an Ethernet LAN). Taking

into account the potential distance between network elements, this will be based on

"Extended Area LAN" concepts such as the MetroEthernet. The primary impact on the

IP-based transport is that all IP addresses of the NEs belong to the same IP subnet.

It has at least one IP router in the BSS transmission network. If needed, this IP router can

be added (anywhere) on top of an Ethernet network, s shown in the example highlighted

in the figure below.

Ethernet switches 1, 2, 3, 4 are access points to the operator's network.

The core Ethernet switch represents the interconnections inside the operator's network.

VLAN tags 1, 2, 3 represent traffic from / to Ethernet LANs 1, 2, 3. They can be

configured on the Ethernet switches 1, 2, 3, 4, the core network nodes, and the router.

Since there are three different VLANs, there are also three different IP subnets, and the

Router must be assigned one IP address in each of these subnets.


....................................................................................................................................................................................................................................

....................................................................................................................................................................................................................................




19/104

A fourth subnet can be defined for the central office, with IP addresses for TC, MFS,

BSC, and the IP router (with VLAN 4). VLAN 1 and two are only needed if the operator

wants to (or must) manage different subnets for BTS in LANs 1 and 2 (i.e. a specific IP

address space for the BTSs in each LAN).

If the same subnet is used for all these BTSs, the same VLAN tag can be used for LAN 1

and 2. VLAN 3 is only needed if BSC is not in this subnet, as well as VLAN 4 for the

Central Office controllers.

No route needs to be configured on the IP router, since only its local interfaces are

involved in the used routes

Layer 3 BSS Architecture

The Layer 3 Alcatel-Lucent OmniSwitch 6850/6850E is used as an example for

configuring the BSS layer 3 architecture.

For more information about OmniSwitch 6850/6850E, refer toAlcatel-Lucent Base

Station Subsystem - BSS O&M Routing Configurations(3MN-01075-1871-PGZZA).

Controllers in Different Networks

MFS, BTS, TC are in different sub networks. In this case, each machine defines its proper

subnet, as shown in the following figure.

20/104

All Controllers in Same NetworkMFS, BTS, TC are in the same subnetwork, as shown in the figure below.

Common subnet allows the operator to:

Simplify the IP management (only one subnet to manage)

Save IP ports on the routers (L3 ports on routers are more expensive than L2 ports).

The MFS IMT, BTS NEM, BSC NEM,TC NEM dialogue with corresponding NE in the

O&M communication plan. NEM remotely connected to an NE are usually located in an

O&M site. To have a NEM connected from a telecom site, the O&M addresses must be

routable up to this site.

MSC and SGSN are not BSS NE but core network NEs with interfaces with the BSS.

General Rules for IP Addressing

Overview

The operator must be able to group the IP addresses according to his own organization.

The operator must be able to use more than one 9130 BSC / MFS Evolution on a singlesubnet. This requirement aims at reducing the number of subnets handled by the external

routers, which allows using lower cost routers. This requirement is especially interesting

when several 9130 BSC Evolution are co-localized or when the 9130 BSC Evolution is

co-localized with the 9130 MFS Evolution.

The operator must be able to separate the O&M IP addresses from the Telecom IP

addresses in two different subnets.

The first and the last IP addresses in a subnet are reserved, respectively to identify the

subnet addresses and the broadcast address. They must be removed from the list of IP

addresses that can be assigned to the hosts. For instance, let assume that Subnet_IP_Addr= 150.100.12.128 and Subnet_Mask = 255.255.255.128. Then, the hosts can be only

assigned in the range 150.100.12.129 to 150.100.12.254.

External router is part of the customer network and it is up to the customer to configure it

with IP addresses.

IP Addressing RulesOverview

IP addresses for a 9130 BSC Evolution can be chosen freely, limited only by the

following rules:

9130 BSC Evolution external addresses must not belong to the following networks:

172.16/16, 172.17/16, 172.18/16

192.168..65, 192.168..66 where means Shelf Geographical

Address and can have the value 3 or 4.

OMC-Rs or other equipment with which the 9130 BSC Evolution interacts must notbelong to the following networks:

172.16/16, 172.17/16, 172.18/16

192.168..65, 192.168..66 where means Shelf Geographical

Customer is free to use these network, provided these networks or machines on this

network do not interact with 9130 BSC Evolution

In the case of an O&M link on ML-PPP (O&M link over Ater), 9130 BSC Evolution

external addresses must not belong to the network 1.1.1.0/29.

O&M and Telecom with one shared subnet

Overview

For both O&M transport and Telecom transport, there is used one external subnet, as

shown in the following figure:

There are dedicated IP addresses for the Telecom transport.

For the definition of the subnet A, the necessary telecom parameters are set in the 9130

BSC Evolution as shwon below:
