1 Product Positioning and Features

About This Chapter

This section describes the positioning and features of the SG7000.

1.1 Product Positioning

This product can be used as the large-capacity signaling transfer point (STP) or the

independent signaling gateway. When acting as the STP, this product implements all functions

of the traditional narrowband STP, that is, processing and transferring the SS7 signaling

messages in the PSTN of traditional circuit domain. When acting as the independent signaling

gateway, this product is located at the edge access layer of the NGN. It uses the Signaling

Transport (SIGTRAN) and Signaling System No.7 (SS7) protocols. The SG7000 achieves the

interworking between the public switched telephone network (PSTN)/public land mobile

network (PLMN) and NGN through SS7, by cooperating with other components in this

network including the softswitch device and IP-based database devices, like IP-SCP, IP-HLR,

and IP-SMSC.

1.2 Product Features

As independent signaling gateway equipment, the high capacity, high processing capability,

and high reliability are the most special features of this product.

network including the softswitch device and IP-based database devices, like IP-SCP, IP-HLR,

and IP-SMSC.

Along with the opening-up of the telecom market and coexistence of multiple operators, the

competition among operators is more serious. The competition steers from the simple price to

providing high-quality and versatile services, exploring customer potential demands, and

Issue 01 (2011-04-22)

classifying customer groups. The investment focus diverts from equipment to value-added

services and network optimization.

Customers have more and more choices. In this case, how to provide better and timely

services to customers to raise customer satisfaction and obtain better economic and social

benefits is the most concerned problem to operators.

Under this background, from the viewpoint of cost saving, network reuse, and service

innovation, operators put forward more specific requirements on the integration of different

networks and service development:

Providing differentiated and competitive services

Providing various services to new customers and upgrading services for previous

customers

Fast introducing new services

Making the best use of the original network resources

Providing industrial and enterprise solutions concerning customer benefit

Reducing maintenance cost

Meanwhile, with the maturity and commercial use of the NGN and 3G network, the previous

signaling network cannot meet the requirement of new signaling services. Especially, the

previous network cannot support developing some subscriber-friendly and competitive

services.

To meet service development requirements, Huawei develops U-SYS SG7000 Signaling

Gateway to meet the continuous development of signaling network and services, meet the

continuous service requirement of customers, enhance comprehensive competitiveness of

networks, and realize continuable development.

Basic Signaling Transfer Point When used as the independent signaling transfer point (STP), the product provides

functions such as SS7 signaling transfer, GT translation, message screening, and

signaling charging for TDM network nodes.

With high processing capability, the product connects large-scale network nodes to

simplify network structure and implement centralized management.

The large capacity and smooth expansion capability set the base for upgrading the

product.

When used as the independent signaling gateway, the SG7000 implements bi-direction

signaling transfer of SS7 and SIGTRAN signaling between TDM and IP networks.

With high processing capability, the SG7000 connects large-scale network nodes to

simplify network structure.

The SG7000 provides the signaling gateway function in the IP domain of 2G networks

and 3G networks.

IP Signaling Transfer Point The product provides the signaling transfer function in the 3G networks.

the product provides the signaling transfer function in the NGN.

Signaling Service Processing Platform

The product can also transfer data between the switches and special service centers like

service control point in the intelligent network (IN) and network management center (NMC).

It meets the requirements on the transmission of signaling messages in the following aspects:

Supporting mobile number portability (MNP) service

Supporting flexible number routing (FNR) service

Supporting signaling firewall gateway (SFG) service

In early signaling networks, the switch and STP are integrated for the sake of cost. The STP in

this mode has low capability and handles a small amount of links. As a result, it is used to

transfer signaling messages in areas that have low signaling traffic. With the expansion of the

telecom network, the demand for signaling interaction increases. The signaling network is

separated from the service network, and the independent STP takes the place of the integrated

STP. In this way, the signaling network built with independent STPs becomes a mainstream

support network.

When the signaling traffic is light, the SG can be integrated into the trunk media gateway

(TMG) and media gateway controller (MGC). When the services increase, the signaling

traffic increases and requires independent SGs. After the independent SGs come into being,



Product Description



Issue 01 (2011-04-22)

2.4 Operating Principles

This section describes the working principles of the system from the viewpoints of the module

function and signaling processing procedure.

2.4.1 Module Functions

This section describes the detailed work related to each module during the entire signaling

processing.

2.4.2 Signaling Processing Procedures

This section describes the signaling processing flow in the narrowband network.

2.4.1 Module Functions

This section describes the detailed work related to each module during the entire signaling

processing.

During the signaling processing, the modules implement the following functions:

The signaling processing unit, LAN drive and IP dispatch unit, and inter-frame

interconnection unit communicate with each other through the shared resource bus, and

report their status to the equipment management unit.

The clock unit provides TDM synchronization clock for multi-frame communication.

The monitoring unit, E1/T1 interface unit and clock unit communicate with each other

through the serial port cable and report the running status to the equipment management

unit.





2-11

The equipment management unit is used for the communication between the foreground

and the background, loading control, statistics and reporting of equipment running status.

The monitoring unit is used for gathering environment information inside the frame and

information on any abnormal functioning of the boards, and reporting them to the

equipment management unit.

2.4.2 Signaling Processing Procedures

This section describes the signaling processing flow in the narrowband network.

The signaling messages from traditional narrowband PSTN/PLMN are processed based on the

following flow:

1. The E1/T1 interface receives signaling messages from PSTN/PLMN, and directs them to

the SG7000 narrowband E1/T1 interface unit.

2. The intra-frame timeslot switching is performed through the TDM switching bus and

then sent to the signaling processing unit.

3. The signaling processing unit identifies the destination point code (DPC) in the message

and determines whether to transfer the signaling messages to the PSTN/PLMN or the IP

network.

4. If a message is to be transmitted the PSTN/PLMN, the narrowband E1/T1 interface unit

forwards it. This is equal to the STP function.

5. If a message is to be transmitted to the IP network, the signaling processing unit

assembles or disassembles the packet; the LAN drive and IP dispatch unit dispatch it.

The message is then transferred to the IP network through the IP interface unit.

The process is reversed when a signaling message comes to the narrowband network from the

IP network.

5.2 Network Management

The SG7000 BAM provides the SNMP/MML interface to connect with the NMC (like

Huawei iManager N2000 and iManager M2000). Therefore, the BAM can be managed by the

NMC. The iManager N2000 or iManager M2000 provides users with the following basic

management functions: topology management, configuration management, performance

management, fault management, and security management. You can also start the SG7000

client through the N2000 or M2000 to perform the remote management and maintenance.

5.2.1 Topology Management

Topology management is used to form and manage the topology structure of the whole

network. By loading the topology data of the network equipment, the system can form a

network topological view the same as the actual network structure. Through the topological

view, the user can view the running of the network, in real time. When the network is running,

the topological view can be consistent with the actual network topology through timed

processing of the reported Trap.

5.2.2 Configuration Management

The configuration management provides the management function from the NE layer to the

network layer, and provides complete management function to the managed equipment, thus

implementing the configuration, query, and operation functions on the equipment.

5.2.3 Fault Management

The fault management system comprises the following: fault management Daemon, real-time

alarm display, history alarm display and trap regulation definition tool.

5.2.4 Performance Management





5-7

The user can obtain the current performance data of the network and set performance

thresholds. If the performance exceeds the threshold, the network informs the NMS through

alarms. The user can also collect the performance data of a certain period and save it in the

database for further analysis. Three modes are provided to display the collected data: broken

line chart, histogram, and pie chart.

5.2.5 Security Management

Security management ensures security of the NMS, including: User management, Operation

log management and User login/logout management.

5.2.1 Topology Management

Topology management is used to form and manage the topology structure of the whole

network. By loading the topology data of the network equipment, the system can form a

network topological view the same as the actual network structure. Through the topological

view, the user can view the running of the network, in real time. When the network is running,

the topological view can be consistent with the actual network topology through timed

processing of the reported Trap.

The topological view adopts the hierarchical structure. At the top of the view are the telecom

view, IP sub-network view and physical view. Different views and sub-networks are divided

under the views to manage the network equipment. All the views and sub-networks can

together be called a sub-map.

Topology management actions include:

Adding equipment or subnets

Querying the status of nodes, links or subnets

To refresh the view, use the automatic or manual polling on the status or data of any

equipment.

Topology management also realizes the following functions:

Changing background image

Setting network object attributes

Saving modification on topological view

Querying network object

Display network object information

Setting display effect of topological view

5.2.2 Configuration Management

The configuration management provides the management function from the NE layer to the

network layer, and provides complete management function to the managed equipment, thus

implementing the configuration, query, and operation functions on the equipment.

The iManager N2000 and iManager M2000 provides the configuration management functions

at the following levels:

Network element (NE) level

Network level

It can:

Provide device management functions

5 OAM Functions


Product Description



Issue 01 (2011-04-22)

Configure devices

Query devices

Operate devices

Provide configuration entrances for devices

Support two modes of configuration management on the NE device

One mode is to double-click the topology node on the topological view to start the device

panel, on which you can perform configuration of the device. The other mode is to configure

the network device through the device explorer provided by the NM platform.

5.2.3 Fault Management

The fault management system comprises the following: fault management Daemon, real-time

alarm display, history alarm display and trap regulation definition tool.

The fault management functions are as follows:

Real-time monitoring of equipment alarm information and operation information

Querying equipment history alarm information and operation information

Defining the received SNMP Trap

Querying and configuring equipment alarm tables

The fault management system collects and processes equipment alarms in one of the

following formats:

SNMP Trap format

MML format

Alarms of the SNMP Trap format are generated by the SNMP equipment. Most broadband

data communication equipment supports this format. Alarms of the MML format are

generated by narrowband telecom equipment, such as HONET access network equipment and

C&C08 switch. The Trap and alarm can be displayed on the same screen or on different

screens.

5.2.4 Performance Management

The user can obtain the current performance data of the network and set performance

thresholds. If the performance exceeds the threshold, the network informs the NMS through

alarms. The user can also collect the performance data of a certain period and save it in the

database for further analysis. Three modes are provided to display the collected data: broken

line chart, histogram, and pie chart.

The collected data can be displayed in one of the following modes:

Fold-line Graph mode: to display the values of each object expression within a certain

time range

Histogram mode: to display the values of object expression at a collection time point

Pie Graph mode: to display the percentage values of the object expressions at a data

collection point

The user can set the interval for polling the performance data as well as the display percentage

and colors of the collected data.





5-9

5.2.5 Security Management

Security management ensures security of the NMS, including: User management, Operation

log management and User login/logout management.

With this function, the authorities for operating the NMS can be controlled. After the NMS

client is started, only authenticated users can log in to the system and carry out certain

operations. All sensitive operations will be recorded. The administrator can check the log to

obtain required information of the system.

Asynchronous Transfer

Mode (ATM )

A network technology based on transferring data in cells or

packets of a fixed size. The small and constant cell size

allows the ATM equipment to transmit video, audio, and

computer data over the same network, and assures that no

single type of data monopolizes the line. ATM creates a

fixed channel, or route, between two points whenever data

transmission begins. This differs from TCP/IP, in which

messages are divided into packets and each packet can take

a different route from source to destination. Thus, it is easier

to track and bill data usage across an ATM network. ATM,

however, is less adaptable to surges in network traffic.

asynchronous

transmission

A transmission method in which all nodes can send and

receive data at any time except the destination node, which

must receive data as soon as the data arrives.

ATM See Asynchronous Transfer Mode.
