Huawei Technologies Co. It describes the estimated capacity, functional modules, configuration and expansion rules, and specifications of the HLR. The protocols and interfaces used are the same as that used by traditional HLRs. It implements the functions such as adding, deleting, updating, and querying data at the requests of the HLR-FE.
Figure shows the logical structure of the HLR At least one cabinet with one subrack must be configured. Smooth capacity expansion can be achieved by adding processing blades or expansion subracks. Table describes the technical specifications of the N68E cabinet. The N68E cabinets are classified into integrated cabinets and extended cabinets. The configuration rules of integrated cabinets and extended cabinets are as follows: An integrated cabinet can be configured with two OSTA 2.
An extended cabinet can be configured with three OSTA 2. Generally, one or two integrated cabinets are configured, whereas the number of extended cabinets to be configured depends on the system capacity. Figure Integrated cabinet and extended cabinet 3. The other slots at the front are used to host universal process blades UPBs. The rear slots are used to host the interface boards of the UPBs.
It receives and processes signaling messages. Data routing DRU : It provides the function of data routing for the system to locate the subscriber data. Data storage DSU : It provides data services for upper-layer applications. It also provides interfaces for interconnection with the provisioning system and the disk array. Each site is configured with one pair of OMU boards. The disk array adopts RAID and hot spare disks to ensure security of subscriber data. Each site is configured with one disk array.
The number of disk arrays configured for a site is permanent; therefore, the disk array does not require expansion. It provides 24 GE interfaces and 4 SEP interfaces, which are responsible for data and signaling access as well as cascading between subracks. Each site is configured with two LAN switches by default for accessing data and signaling.
If more than four subracks are deployed, one pair of LAN switches needs to be added for subrack cascading. One pair of LAN switches is added at a time. Third-party software The third-party software consists of: Operating system of boards: The boards in each subrack are configured with one Linux operating system.
Service application software used on the disk arrays and OMU boards. The processing capability of a board varies according to service models or traffic models. For details on service models and traffic models of Huawei, see Appendix.
Based on the actual number of subscribers supported and processing capability, you can determine the number of service processing units, data service units, and subscriber data management units to be configured. Table describes the list of the minimum configuration of the HLR LAN switch 2 - Disk array 1 One disk array is configured. Figure shows the minimum configuration of the HLR Table describes the list of the typical configuration of the HLR Figure shows the typical configuration of the HLR Table describes the list of the maximum configuration of the HLR Figure and Figure show the maximum configuration of the HLR It is supported by SingleSDB 3.
It is quoted when the HLR needs to be upgraded from the version serving only 2G subscribers to the version serving both 2G and 3G subscribers. It is quoted based on the number of subscribers stored in HLR V This item is quoted only for redundancy HLRs. If this function is required, it is quoted based on the number of static subscribers stored in the HLR.
It helps to improve the reliability of the IP networking. If no more than two service models are configured, this service is quoted based on the number of 3G GPRS dynamic subscribers. Reserve one ETIA2 for each site if narrowband networking is adopted. The spare parts are quoted separately. You only need to add the boards as required for implementing a hitless evolution.

The HLR provides the following functions: Subscriber Data Management The HLR stores and manages the following data related to its home subscribers: identification data, basic service subscription data, supplementary service subscription data, feature service subscription data, roaming restriction data, Intelligent Network IN service subscription data and template configuration data. In order to prevent unauthorized subscribers from accessing the network, and to ensure communication security for mobile subscribers, the HLR also stores authentication data. Mobility management involves location registration, location cancellation, and dynamic data query. Have a requirement? Get Best Price.
