Overview of the HLR9820

The HLR9820 is shared by the Circuit Switched (CS) domain and the

Packet Switched (PS) domain on the GSM or UMTS network. It

provides the functions of the HLR. Logically, the HLR9820 consists of

the BE and the FE, which implement independent data storage and

service processing. The functions of the BE and the FE are as follows:

BE

The BE stores the subscriber data. It adds, deletes, updates, and

queries data at the request of the FE.

FE

The FE processes signaling messages and service logics and obtains

data from the BE.

Overview of the HLR9820 (Cont.)

Based on whether an independent operations and

maintenance unit (OMU) is configured for the FE and BE,

the product applications for the HLR9820 are as follows:

� Integrated deployment: The FE and BE are configured

with only one OMU.

� Separated deployment: The FE and BE are configured

with independent OMUs.

Advanced Hardware Platform The GU HLR9820 adopts the OSTA 2.0 hardware platform that is compatible with the

Advanced Telecom Computing Architecture (ATCA).

The OSTA 2.0 platform has the following advantages:

�The equipment and monitoring system comply with the carrier-class application design.

�The service plane, control plane, and management plane are physically separated. Therefore,

the lower-layer hardware planes are not adversely affected by other planes. If the hardware

needs to be upgraded, the software can still be used without any modification. Therefore, the

system reliability is greatly improved.

�The components used in the OSTA 2.0 platform comply with the component selection

specifications for carrier-class equipment and the ETSI/NEBS standards.

�The system is enhanced with the function of monitoring the system operation, hardware

components, and external interfaces. In addition, it adopts the fault diagnosis mechanism and

provides pre-alert when a component is in a border line state between normal operation and

fault.

�The OSTA 2.0 platform meets the sound-proof and heat dissipation requirements for

telecommunications equipment.

�The OSTA 2.0 platform adopts fault detection and fault isolation technologies. Therefore, the

detected faults are isolated and will not adversely affect the running of other parts of the

system.

�The OSTA 2.0 platform adopts optimized fault location design, which allows accurate

identification of a faulty component.

� IPMB, Base, and Fabric buses are configured in OSTA 2.0 subracks.

� The intelligent platform management bus (IPMB) is the monitoring and

device management bus of the OSTA 2.0 subrack. It connects all the

devices in the OSTA 2.0 subrack. The IPMB allows the SMM to manage all

the hardware in the subrack.

� The BASE bus is the management and control bus of the OSTA 2.0

subrack. It provides a channel for software loading, alarm reporting, and

maintenance message delivery. All boards are connected to the SWU

through the Base plane. The SWU exchanges maintenance messages

among all the boards.

� The FABRIC bus provides a data channel for the system service plane. It

transmits the service information of the system. All the UPBs are

connected to the SWU through the FABRIC bus. They exchange service

messages through the SWU.



The boards can be classified into the following types based on their position:

� Front board

The front boards, located in the front of a subrack, can be classified into the following types:

� Universal Process Blade (UPB): processes data and services by using the service applications

running on the board.

� Switching Unit (SWU): implements layer-2 network switching and optical switching.

� System Management Unit (SMU): manages the components in a subrack.

� Back board

The back boards, installed back-to-back with the front boards, provide interfaces for the front

boards. The back boards can be classified into the following types:

� Universal Service Interface Unit (USI): interface board of the UPB

� Switching Interface Unit (SWI): interface board of the SWU

� Subrack Data Module (SDM): interface board of the SMM

� Backplane

The backplane is located between the front boards and the back boards. It transmits signals

between boards.

Functional Structure

Logically, HLR9820 consists of the front end (FE) and back end (BE). The FE processes protocols

and services. The BE stores, queries, and manages subscriber data.

In terms of functions, the UIM consists of five functional subsystems, the signaling processing

subsystem, the subscriber data management subsystem, the data service subsystem, the data

storage subsystem, and the O&M subsystem.

18


Signaling Processing Subsystem

The signaling processing subsystem provides the following functions:

� The signaling processing subsystem receives and processes signaling

messages. It consists of the Broadband Signaling Gateway (BSG) and

Call Control Unit (CCU).

� The BSG processes signaling messages at the MTP2 layer and MTP3

layer and forwards the processed messages to the CCU.

� The CCU completes protocol processing at the SCCP, TCAP, and MAP

layers, as well as service processing. It obtains subscriber data from

the data service subsystem and modifies the subscriber data.

The signaling processing subsystem is deployed on GUFEU boards,

which are physically implemented by UPBA0 boards.


Subscriber Data Management

SubsystemThe subscriber data management subsystem provides the following

functions:

� Supports centralized service provisioning for different FEs.

� Provides open Human-Machine Language (MML) and Simple Object

Access Protocol (SOAP) interfaces.

� Supports connection from Web clients.

� Implements authentication and authority verification on the users of

the provisioning system and Web clients.

� Manages subscription data.

The subscriber data management subsystem is deployed on USPGW

boards, which are physically implemented by UPBA2/UPBA6 boards.

19


Data Service Subsystem

� The DRU provides the data routing function.

� The subscriber data is stored in multiple DSU clusters. Based on the

subscriber identity, the DRU identifies the DSU cluster in which the

required subscriber data is stored, and then selects a DSU node based

on the load balancing strategy to provide data services.

� The DSU serves as the in-memory database of the USCDB. It performs

the functions of adding, deleting, updating, and providing data upon

request, processing data requests, and returning the processing result.

The data service subsystem is deployed on USDRU/USDSU boards,

which are physically implemented by UPBA2/UPBA6 boards.


Subscriber Storage Subsystem

� The data storage subsystem consists of DMU boards and the

disk array.

� The physical database is independent of service processing. It

provides only permanent storage of global data, subscriber

data, and route data.

The physical database is deployed on the DMU board, which

connects to the disk array through fabric cables. It uses the

Oracle database management software.

The DMU board is physically deployed in UPBA2/UPBA6 boards.

20


O&M Subsystem

� The functions of the O&M subsystem are implemented by OMU

boards. Typically, a pair of OMU boards is configured in slots 0 and 2

in the basic subrack.

� The two OMU boards work in active/standby mode.

� Active and standby OMU boards periodically send heartbeat messages

to each other to notify their peer nodes of their current state.

� If the FE and BE are deployed in integrated mode, the FE and BE are

managed by the same O&M subsystem. If the FE and BE are deployed

in separate mode, the FE and BE are managed by different O&M

subsystems. OMU boards are physically deployed on UPBA2/UPBA6

boards.
