> RoHC Profile Common Options Configuration Mode Commands
> The RoHC Profile Common Options Configuration Mode is used to set timers that, upon expiration, release header compression contexts.
> delay-release-hc-context-timer
> Sets a delay in releasing RoHC contexts allowing for context continuation during intra-gateway handoffs.
> Product
> HSGW, PDSN
> Privilege
> Administrator
> Syntax
> delay-release-hc-context-timer seconds
> no delay-release-hc-context-timer
> no
> Removes previously configured value for this command. No value disables the feature.
> seconds
> Specifies the number of seconds the system delays before releasing the header compression context. seconds must be an integer value from 0 to 65535.
> Usage
> 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.
> Example
> The following command sets the header compression release delay to 20 seconds:
> delay-release-hc-context-timer 20
> end
> Exits the current mode and returns to the Exec Mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Change the mode back to the Exec mode.
> exit
> Exits the current mode and returns to the previous mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Return to the previous mode.
> inactive-traffic-release-hc-context-timer
> Set an inactivity timer that is checked when inactivity is detected on an SO67 A10 bearer connection with negotiated RoHC parameters. If the inactivity continues to the end of the configured time, the header compression context is released.

> HSGW, PDSN
> Privilege
> Administrator
> Syntax
> inactive-traffic-release-hc-context-timer seconds
> no inactive-traffic-release-hc-context-timer
> no
> Removes previously configured value for this command. No value disables the feature.
> seconds
> Specifies the time, in seconds, the system waits for activity on the bearer channel before releasing the header compression context. seconds must be an integer value from 1 to 65535.
> Usage
> Use this command to set a timer that is started upon detecting inactivity on the bearer channel. Upon expiry, the header compression context is released. Enable this feature to allow for efficient memory utilization.
> Example
> The following command sets the bearer channel inactivity timer to 60 seconds:
> inactive-traffic-release-hc-context-timer 60
