The Gateway Location Application (GLA)

The Gateway Location Application (GLA) is a DSR Application that provides a Diameter interface to subscriber data stored in the DSR's Policy Session Binding Repository (SBR). Subscriber data concerning binding and session information is populated in the SBR-B (Policy SBR - Binding) by the Policy Diameter Routing Agent (Policy DRA). GLA provides methods for a Diameter node to query binding information stored in the SBR-B. The query can be by either IMSI or MSISDN.

GLA processes Diameter Requests and generates Diameter Answers. It does not route Diameter Requests to other Diameter nodes. A Diameter Peer Node can be a Gateway Query Client (GQC). GLA allows DSR to be a Gateway Query Server (GQS).

GLA provides the following capabilities:

• Ability to configure GLA exceptions
• Ability to configure GLA system options
• Ability to configure GLA alarm thresholds
