HP HLR / EIR solution implements the function of register of the GSM network equipment, which allows to maintain a database and manage its status when registred in the network. In addition to the functionality defined by the standard, EIR also implements the function ADD (Automatic Device Detection), which allows real-time tracking of change phone number, and send appropriate notification to the platform DMS (Device Management System). EIR functionality is implemented within the product HP HLR, and is part of it.

The product implements the Equipment Identity Register function in GSM networks.

Hardware & Software

HLR solution can be deployed on a hardware platform HP NonStop Server NS-series or NB-series.

HP Integrity NonStop Server – a server that belongs to the category of High-End. It is based on the use of HP NonStop Kernel operating system, ServerNet architecture and fully redundant elements, which ensures the highest levels of availability and fault tolerance. Integrity NonStop Server is ideal for the operation of the most critical business applications.

Technical Description

Functionality:
  • Support of white, black and gray lists;
  • Block registration of stolen or “doubtful” phones;
  • Detection of real-time change of the phone (ADD);
  • Analyze IMEI for the first 14 digits;
  • Supports UESBI value according to 3GPP TS 25.413;
  • Allows you to bind to a single IMEI and IMSI to prohibit the use of other IMEI for that IMSI;
  • Provisioning interface uses the CORBA protocol and allows to put data in the database on individual IMEI or within a range of IMEI;
  • Ability to upload / download IMEI lists from EIR database;
  • Cloned devices detection (checking that the IMEI number IMSI);
Benefits
  • Increase ARPU by:
    • Increasing penetration of VAS-services;
    • New sources of income;
  • Reduce costs through:
    • More efficient loading of Call-centers;
    • More rapid launch of new VAS-services;
  • Improve the service by:
    • Maintaining a real-time register of mobile;
    • A simple interface to the VAS;
  • Scalable both horizontally and vertically.;
  • Implemented with a robust HP NonStop Server platform with Mated-pair configuration reliability 99.99999%, which almost eliminates unplanned downtimes;
  • OpenCall HLR is the world’s first HLR, based on the server-side components;
  • More than 200 million active subscribers served by the OpenCall HLR, established in CDMA, and in GSM / UMTS networks;
  • More than 35 operators around the world use OpenCall HLR;
  • Technical Implementation

    The solution is implemented with a robust HP NonStop Server platform.
    It supports following interfaces:

    • GSM MAP
    • HTTP — Hyper Text Transfer Protocol Version 1.1
    • XML
    • CORBA IIOP interface

    ADD (Automatic Device Detection) requires SGSN and switches to support modified checkIMEI messages, containing at least the IMSI and optionally – MSISDN. The solution can get IMSI and MSISDN from the dialogue part TCAP of checkIMEI message, and also from its component part. If MSISDN is not in checkIMEI message, then it is read from HLR database by IMSI.

    The figure below shows an example of query diagram of checkIMEI message processing with active function ADD (Automatic Device Detection). After the formation of triplet IMSI-MSISDN-IMEI, system informs DMS using HTTP / XML format to change the parameters of user equipment.
