6.1.8 Audit of MRFP p. 80

6.1.8.1 Audit of Value p. 80

The MRFC may request the MRFP to report the current values assigned to distinct objects in the MRFP.

6.1.8.2 Audit of Capability p. 81

The MRFC may request the MRFP to report the capabilities of distinct objects in the MRFP.

6.1.9 MRFP Capability Change p. 81

The MRFP reports a change of capability of distinct objects in the MRFP.

The MRFC can 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 MRFC discovers that it wants to go out of service it starts an MRFC Out of Service procedure. The MRFC can indicate whether it requires the context to be cleared immediately (forced) or cleared when all terminations are released.(Graceful)

6.1.11 MRFP Resource Congestion Handling - Activate p. 82

When the MRFC requires that an MRFP congestion notification mechanism be applied in the MRFP, the MRFC shall use the MRFP Resource Congestion Handling - Activate procedure towards the MRFP.

6.1.12 MRFP Resource Congestion Handling -Indication p. 82

When the MRFC receives a load reduction notification from the MRFP via the MRFP Resource Congestion Handling - Indication procedure, the MRFC tries to reduce the processing load that the MRFC creates on the MRFP. The MRFP shall decide the actual level of traffic reduction.

6.1.13 Hanging termination detection p. 82

Whenever requesting new IP bearer terminations, the MRFC shall request the MRFP to periodically report termination heartbeat indications to detect hanging context and termination in the MRFP that may result e.g. from a loss of communication between the MRFC and the MRFP.

When the MRFC receives a termination heartbeat notification from the MRFP via the Termination heartbeat - Indication procedure, the MRFC shall return a Termination heartbeat - Indication Ack (without an error) if the context id / termination identity combination exists in the MRFC. If it does not exist, the MRFC shall return an error and shall correct the mismatch, e.g. by requesting the MRFP to subtract the indicated termination and to clear any associated context.
