Sets a delay in releasing Robust Header Compression (RoHC) contexts allowing for context continuation during intra-gateway handoffs.
Exec > Global Configuration > RoHC Profile Configuration > RoHC Profile Common Options Configuration
configure > rohc-profile profile-name profile_name > compression-options
Entering the above command sequence results in the following prompt:
delay-release-hc-context-timer seconds no delay-release-hc-context-timer
Removes previously configured value for this command. No value disables the feature.
Specifies the number of seconds the system delays before releasing the header compression context as an integer from 0 to 65535.
Use this command to set a delay in releasing a header compression context. THis command is necessary when employing RoHC and mobility. Typically, when an RP connection is released, the header compression context is also released immediately. However, in mobility situations, such as intra-PDSN handoffs, the header compression context should be preserved. Adding a delay to cover the handoff time allows the context to be maintained.
A header compression context contains the compression/decompression configuration and statistics for the session.
