The Home Location Register (HLR) Emulator allows you to validate network performance and capacity in a realistic network environment with a mix of subscriber profiles, replicating a deployed configuration. As an HLR simulator, it provides mobile subscriber data repository, authentication information, and routing information services for SGSN, GGSN, GMSC, and VLR testing in UMTS networks.
Network Interface Support
The following 3G HLR interfaces are supported:
When an HLR Emulator is configured with multiple interfaces, it also supports the interaction between those interfaces.
- Multiple Gr interfaces enable support for SGSN-SGSN mobility;
- Concurrent Gr and C interfaces enable the emulator to automatically notify an SMS-GMSC when a subscriber becomes available for MT short message delivery.
Execute timed chains of test events with a run-time command or during an automated test to trigger HLR initiated procedures.
- Cancel Location;
- Ready for Short Message;
- Reset.
Emulator Configurations
One HLR Emulator can support any mixture of the interfaces shown in the diagram above, up to a maximum of 1000 client connections. Multiple HLR Emulators can be instantiated on a single server. In this mode each emulator can support multiple interfaces, up to an aggregate of 1000 client connections across all emulators. The HLR nodes are fully independent and their subscriber configurations may also be independent, overlap, or be duplicated.
