Activate PDP Context Control

Last updated: November 11, 2010

This section is only applicable to the lab application.

You may configure the test set to ignore or reject an Activate PDP Context Request from the UE. You can choose what value is sent in the SM Cause information element of the Activate PDP Context Reject message using the Activate PDP Context Reject SM Cause setting. Use this function in parallel with Protocol Logging to verify that the UE behaves in a manner conforming to the standards for this situation and for each associated SM Cause value.

Activate PDP Context Reject SM Cause

WhenActivate PDP Context Reject State isOn , you may specify what value is sent in the SM Cause information element using theActivate PDP Context Reject SM Cause setting. From the front panel, you may choose from the valid causes specified in 3GPP TS 24.008 10.5.6.6.

If you selectCustom Value from the front panel, a value of 0 is sent to the UE.

The CALL:SERVice:GPRS:REJect:CAUSe command allows you to send any value between 0 and 255 to the UE, even those not mapped to a cause in the standard. If you send a value other than those listed in the above table via the GPIB command, the front panel setting displaysCUSTOM .
