About the Session Loading With Mobility Test
With the Session Loading With Mobility test, you can test the SUT's ability to process a mix of activities for a long period of time, as it would in a commercial network. You can define a real-world activity model for the test so that the SUT is handling multiple events, such as session connects, handoffs, and disconnects, at the same time. You can further refine the activity model by adding data traffic and applying distribution models to the control and data traffic rates. The mobility test is similar to the Session Loading Test in that session loading runs — a number of sessions are connected, maintained, and disconnected — are repeated through the life of the test.
The Session Loading With Mobility test begins by establishing sessions at the session connect rate. When the handoff time expires, the session is handed off for a number of times, using the handoff time as a delay timer between handoffs. The session is then maintained for a hold time, disconnected and left idle for a session pending time, and then re-established. You define the rates at which the sessions are connected, the hold and pending times, the number of handoffs performed, and the handoff time.
The test continues in this manner through the duration of the test session or until the test is stopped manually or with Automation Control. At that time, all sessions are disconnected at your defined disconnect rate.
CDMA2000 Testing
The Session Loading With Mobility test is available in the following test cases:
-
The CDMA FA Nodal test case tests a PDSN-FA's stability while processing handoffs between emulated PCFs.
-
The CDMA HA Nodal test case tests an HA's stability while processing handoffs between emulated PDSN-FAs.
-
The CDMA End-to-End Mobile IP test case tests an HA and two PDSN-FAs while performing handoffs between the PDSN-FAs.
-
The CDMA Simple IP and CDMA Simple IP VPN test cases test a PDSN's stability while processing handoffs between emulated PCFs.
GPRS Testing
The Session Loading With Mobility test can be used in the GGSN Nodal test case to test a GGSN's stability while processing handoffs between emulated SGSNs.
IP Data Testing
The Session Loading With Mobility test can be used in the PDG Micro-Mobility test case to test a PDG's stability while MNs move between wireless access nodes and receive new local IP addresses.
Mobile IP Testing
The Session Loading With Mobility test can be used in the IPv4 HA Nodal test case to test an HA's stability while processing handoffs between FAs or between co-located addresses. In the CDMA/WiFi Convergence test case, it can test the stability of a PDIF while it maintains IPSec connections with the MNs while they move between co-located care-of addresses or while it processes handoffs between WiFi and CDMA2000 networks.
UMTS Testing
The Session Loading With Mobility test can be used in the UMTS test case to test an SGSN's stability while processing handoffs between emulated RNCs.
WiMax Testing
The Session Loading With Mobility test can be used in the WiMax Nodal test case to test a WAC's stability while processing handoffs between emulated Base Stations.
Compatible Test Options
-
The Data Traffic option can be used to send bearer traffic using the data protocol, volume, and rate that you define through the established sessions, adding to the real-world activity model.
-
The SUT Query option can be used to monitor the SUT CPU usage or dynamically adjust the connect and disconnect rates to based on the CPU usage.
