8.7 Mapping of Parameters for the Reset Procedure

29.3053GPPInterWorking Function (IWF) between MAP based and Diameter based interfacesRelease 17TS

8.7.1 Reset (v1 or v2) mapping to RSR

When the IWF needs to construct a RSR command as a result of receiving a MAP-Reset message with AC version 1 or version 2 (see sections 7.7.1 step 2, and 7.7.2 step 4), the the IWF shall populate AVPs of RSR as described below:

Auth-Session-State AVP shall be set to the value NO_STATE_MAINTAINED (1).

User-Id AVPs shall be populated with the values received within the HLR-Id parameters within hlr-list within ResetArg.

Supported-Features AVP shall be absent.

8.7.2 RSR mapping to ResetArg (v1 or v2)

When the IWF needs to construct MAP-Reset message as a result of receiving a RSR command (see section 7.7.2 step 2), the IWF shall open a MAP dialogue in version 1 or version 2 according to an implementation option; note that the IWF shall be prepared to fall back to v1 when v2 is chosen. Sub-parameters of ResetArg shall be populated as described below:

networkResource in ResetArg (only v1) shall be set to hlr.

hlr-Number in ResetArg shall be populated with a value locally assigned to the IWF and consistent with SS7 routing principles.

hlr-List in ResetArg shall be populated with values received within User-Id AVPs within RSR.
