Troubleshooting: GGSN Response Timeout during SM
|
lFault symptom: The trace result shows that the SGSN sends the Activate PDP Context Reject message carrying the 0x1E cause value "Activation rejected by GGSN.“ lFault location: In the user trace task, check whether the SGSN sends the Create PDP Context Request message to the GGSN. If the SGSN does not receive a response message returned by the GGSN within T3 x N3 seconds, it indicates that a GGSN processing error occurs. lTroubleshooting: p1. Check that the GGSN address in the message is correct. p2. Check the IP connections between the SGSN and the GGSN. |
