dsTest® provides gsmSCF server emulation and client simulation capabilities with the Ge Interface application. Test SGSN GPRS dialogues and CAMEL interworking in UMTS networks with our GSM Service Control Function (gsmSCF) Emulator. Use the Ge Interface application to test the capacity and performance of an gsmSCF.
A rich set of operational measurements is collected at specified intervals and stored in a SQLite database on the dsTest server. Real-time measurements may be retrieved through our dsClient™ CLI interface or graphed via our dsClient GUI interface.
Implementation
The Ge application implements the following CAMEL features:
- Trigger Detection Point Requests (TDP-R)
- Event Detection Point Requests (EDP-R)
- Event Detection Point Notifications (EDP-N)
- Session Dialogue (GPRS session and related PDP contexts controlled within a single GPRS dialogue)
- PDP Context Dialogue (each PDP context is controlled with a separate GPRS dialogue)
Server Emulation
The gsmSCF Emulator supports both controlling and monitoring roles and instructs the SGSN when indicated, eliminating the need to dedicate a production server to lab activities.
Client Simulation
The Ge Interface application can be used to simulate an SGSN’s Ge interface to determine the impact of new gsmSCF features and standards before they are deployed in a network. The Ge Interface application allows users to validate gsmSCF performance and capacity in a realistic network environment, replicating the deployment configuration.
Execute timed chains of test events with a run-time command or during an automated test to trigger client-initiated procedures.
- Start and stop specified subscriber sessions, simulating real-world subscriber activity
- Shift the gsmSCF between control and monitor modes by initiating TDP-Rs, EDP-Rs, and EDP-Ns
- Use multiple service node emulators to simulate SGSN-SGSN mobility
Multiple SGSN nodes can be instantiated on a single server, each with scalable subscriber loads and transaction rates. In this mode, up to 1000 independent SGSN nodes may be simultaneously simulated. The nodes are fully independent and their subscriber configurations may also be independent, may overlap, or may be duplicated.
