Descriptions

The HLR entity is integrated in the MSS. The HLR database is for storage and management of subscriber information. The HLR stores permanent subscriber data including a subscriber's service profile, location information and activity status. When a mobile user buys a subscription from the service provider, the user is registered in the HLR.

The basic functions of the HLR includes:

•Storage of the subscriber database

•Provisioning of data for the VLR

•Subscriber data query and modification via EMS GUI

•Periodic database update queries for VLR update

The information stored in the HLR includes the following:

•Subscription information

•Location information enabling the charging and routing of calls towards the MSC where the Mobile Station (MS) is registered, for example the MS Roaming Number, the VLR Number, the MSC Number and the Local MS Identity.

•Telecommunication and bearer services subscription information

•Service restrictions - roaming limitations

•Parameters attached to supplementary services
