CSCuh25810 - SGW Session Idle Timer
Feature Changes
S-GW Session Idle Timer
A session idle timer has been implemented on the S-GW to remove stale session in those cases where the session is
removed on the other nodes but due to some issue remains on the S-GW. Once configured, the session idle timer will
tear down those sessions that remain idle for longer than the configured time limit. The implementation of the session
idle timer allows the S-GW to more effectively utilize system capacity.
removed on the other nodes but due to some issue remains on the S-GW. Once configured, the session idle timer will
tear down those sessions that remain idle for longer than the configured time limit. The implementation of the session
idle timer allows the S-GW to more effectively utilize system capacity.
This feature is supported only for Pure S calls on the SAE-GW.
Important:
The session idle timer feature will not work if the Fast Data Path feature is enabled.
