2 Main Features

2.1 Distributed Structure The distributed structure allows multiple functional entities that are identical in a system to work in load-sharing mode to accomplish a certain function. The most distinguished feature of the distributed structure is resource sharing in the system. When any functional entity fails, the load will be automatically switched over to other functional entities. Thus, the service provisioning of the entire system is not adversely affected.

Figure 2-1 illustrates the distributed structure.

Figure 2-1 Distributed structure of the HLR9820

FE: Front End OMU: Operation and Maintenance Unit NMS: network management system BE: Back End PGW: Provisioning Gateway



of 41

The distributed structure of the HLR9820 has the following advantages:

l High reliability When any functional entity fails, the load is automatically switched over to other functional entities. Thus, the service provisioning of the system is not adversely affected.

l Smooth expansion During system expansion, only the related functional entities need to be added. After detecting that the newly added functional entities are running stably, the system automatically distributes the load evenly. Thus, the service provisioning of the system is not adversely affected during the system expansion.

2.2 Separate Data Processing and Service Processing The HLR9820 consists of the HLR-BE and the HLR-FE. It supports separate deployment of the data part and the service part.

The separate deployment of the data part and the service part endues the HLR9820 with the following advantages:

l More flexible networking The BE and FE can be deployed in different places. Thus, carriers can determine the number and location of BEs and FEs based on the population distribution and geographical conditions.

l Enhanced system compatibility The BEs of the HLR9820 provide standard and open data access interfaces, through which the third-party equipment can access the HLR9820. Thus, carriers need not address the problem of interconnecting systems of different suppliers.

2.3 Large Capacity and High Integrity The HLR9820 provides large capacity and high integrity. The standard configuration of five cabinets can support up to 100 million active subscribers or 200 million static subscribers. It helps carriers to implement centralized management and to cut down the OPEX.

The OSTA 2.0 platform adopts the Intel Architecture (IA), which allows the high-performance and low-consumption processor, and the Carrier Grade Linux (CGL) technology. It is a highly competitive server provided by Huawei for telecommunications and IT markets.

In addition to complying with the ATCA standards, the OSTA 2.0 platform has the following advantages:

l The whole equipment and monitoring equipment comply with the carrier-class application design.

l The service plane, control plane, and management plane are physically separated. Thus, the lower-layer hardware planes are not adversely affected by other planes. When the hardware needs to be upgraded, the software can be used without any modification. Thus, the system reliability is greatly improved.

l The devices used in the OSTA 2.0 platform comply with the device selection specifications for carrier-class equipment and the ETSI/NEBS standards.

l The system is enhanced with the monitoring on equipment running, hardware components, and external interfaces, and added with the fault diagnosis mechanism and pre-alert for the subhealth status.

l The OSTA 2.0 platform meets the soundproofing requirements and heat dissipation requirements for carrier-class equipment.

l The OSTA 2.0 platform adopts automatic fault detection and fault isolation technologies. Thus, the fault detected can be isolated and will not adversely affect the running of other parts.

l The fault location design allows accurate identification of the faulty device.

2.5 Seamless Geographic Redundancy Solution The HLR9820 allows the FEs and BEs to be deployed in different places. Data synchronization between the BEs in different places is implemented through real-time data duplication and data consistency is ensured through periodical data consistency checks.

The seamless geographic redundancy solution has the following advantages:

l Service switchovers are highly automatic, thus improving the network security. l Mature IT and IP technologies are adopted, thus reducing infrastructure construction

costs. l The seamless geographic redundancy solution can simplify the network structure and

equipment O&M, thus reducing the overall costs.



of 41

In addition to the seamless geographic redundancy solution, the HLR9820 provides the following redundancy solutions: l N+1 mated redundancy solution: The N+1 mated redundancy solution allows the networking of N

(N ≤ 16) active HLRs and one redundancy HLR. All the HLRs are provided by Huawei. l N+1 compatibility redundancy solution: The N+1 compatibility redundancy solution allows the

networking of N (N ≤ 16) active HLRs and one redundancy HLR. The active HLRs can be provided by different vendors, and the redundancy HLR must be provided by Huawei.

2.6 Multi-Level Data Backup Mechanism The HLR9820 adopts the multi-level data backup mechanism. The multi-level data backup mechanism enables subscriber data to be stored in different physical data storage devices, ensuring the security of subscriber data.

The multi-level data backup comprises:

l Level-1 backup The subscriber data is stored in the memories of different boards. Multiple boards form a cluster. Each cluster consists of a master node and a slave node. The master node provides service, while the slave node works as backup. The data of the master node is synchronized to the slave node.

l Level-2 backup The subscriber data stored in the board memory is backed up to the local hard disk of the board. Two local hard disks work in RAID 1 mode.

l Level-3 backup The subscriber data stored in the board memory is backed up to the disk array. The disk array has nine hard disks working in RAID10. Hot spare disks are configured for the hard disks of the disk array.

2.8 Standard and Open Data Access Interface In traditional deployment of new services, carriers have to focus on:

l Service logics l Complicated subscriber data management, including:

− Data structure design − Data storage − Data backup − Data redundancy − Data security mechanism − Data operations

The diversity of equipment provided by different vendors and different data management mechanisms slow down the development of new services. Failing to promptly deploy new services hinders carriers from forestalling the competition predominance.

The HLR9820 provides a standard and open data access interface, through which the third-party applications can obtain the subscriber data. This feature greatly slashes the service deployment cost, simplifies the data complexity caused by the emergence of new services, and helps carriers to provide new services.

2.9 Comprehensive Data Statistics and Analysis The HLR9820 backs up the subscriber data to an independent server at the specified time. Through the independent server, users can query and learn the subscriber data in detail.

This offline data processing mode helps carriers to learn:



of 41

l Subscriber data of specific services l Overall subscriber information, including:

− Service subscription and development trend − Roaming ratio − Network service features

Based on the information, carriers can learn the network operation, understand subscribers' behavior better, and adjust market strategies in time. Thus, the HLR9820 can help carriers to provide tailored services and gain competition predominance.
