Feature Description

An Idle Timer is supported to identify and remove idle sessions that occur in the SAE-GW.

A session becomes idle in some cases where the session is removed from other network nodes, but due to a technical mishap the session could still remain on the SAE-GW leading to resources being held by these idle sessions.

The Idle Timer, once configured, removes those sessions that remain idle for longer than the configured time limit effectively utilizing the system capacity.


Important

This feature is currently restricted to Pure-P and Collapsed Call.


Limitations

The Idle Timer feature does not support recovery of Idle Timer in case of redundancy events.

Configuring Idle Timer for SAE-GW Sessions

The Idle Timer is configurable at APN level.

Use the following commands to configure the idle timer for SAE-GW sessions:

configure 
   context context_name 
      apn apn_name 
         timeout idle timeout_value 
         no timeout idle 
         default timeout idle 
         end 
  • no : Disables the idle timer configuration.

  • default : Configures the default value for subscriber’s time out settings. The default idle timeout value is 0.

  • idle timeout_value : Designates the maximum duration a session can remain idle, in seconds, before system automatically terminates the session. Must be followed by number of seconds between 0 and 4294967295. Zero indicates function is disabled.
