The GGSN Nodal Test Case


The GGSN Nodal test case provided with the GPRS application allows you to test a GGSN in a standalone (nodal) configuration. The test system emulates the mobile nodes (MN) from the aspect of creating unique identifiers for each mobile subscriber and associated primary PDP and secondary contexts, and emulates functional SGSN nodes that service the PDP contexts. The SGSN nodes generate traffic towards the GGSN, and listen for and respond to messages from the GGSN.

With this test case, you define:

Test Terminology

An MN session is the result of a mobile subscriber successfully registering a PDP context with a GGSN. The phrases MN session and PDP context are used interchangeably in this documentation, as are mobile subscriber and mobile node (MN). Each primary or secondary PDP context associated with one mobile subscriber is recognized as one MN session. The terms used for the various states that a session transitions through are defined as follows:

Test Options

When your test activity measures processing capability rather than rates, you can expand the scope of the test:
