6.1.6 IMS-AGW Re-register p. 83

When the IMS-ALG requests an IMS-AGW to perform a registration (see clauses 6.1.3, 6.1.4 and 6.1.7), the IMS-AGW performs a re-registration to the IMS-ALG which is defined in the IMS-ALG address.

6.1.7 IMS-AGW Re-registration Ordered by IMS-ALG p. 83

If the IMS-ALG knows that communication is possible, but the IMS-AGW has not registered, the IMS-ALG can order re-registration of the IMS-AGW.

If the re-registration request is accepted the IMS-AGW uses the IMS-AGW Re-register procedure to register with the IMS-ALG.

The IMS-ALG may request the IMS-AGW to report the current values assigned to distinct objects in the IMS-AGW. This procedure may be used when a change has occurred in the IMS-ALG such that the IMS-ALG is unsure of the current Service State of Terminations.

6.1.8.2 Audit of Capability p. 84

The IMS-ALG may request the IMS-AGW to report the capabilities of distinct objects in the MGW.

6.1.9 IMS-AGW Capability Change p. 84

The IMS-AGW reports a change of capability of distinct objects in the MGW.

The IMS-ALG may use the Audit Value and/or Audit Capability procedures to obtain further information, about the objects whose capabilities have changed.

(⇒ copy of original 3GPP image)

If an IMS-ALG discovers that it wants to go out of service it may start an IMS-ALG Out of Service procedure. The IMS-ALG can indicate whether it requires the context to be cleared immediately (forced) or cleared as the bearer control protocol clears the bearer (Graceful).
