8.8.1 NOR mapping to UpdateGprsLocation-Arg

8.8.2 UpdateGprsLocation-Arg mapping to NOR

When the IWF needs to construct a NOR command as a result of receiving a MAP-UpdateGprsLocation message with a pdn-gw-update parameter within eps-info or with an isr-Information parameter within eps-info not indicating updateLocation or with a skipSubscriberDataUpdate parameter within add-info or with ue-srvcc-Capability parameter but without usedRAT-Type parameter (see section 7.8.2 step 4), the the IWF shall populate AVPs of NOR as described below:

Service-Selection AVP shall be present if apn was received within pdn-gw-update parameter within eps-info within UpdateGprsLocationArg.

NOR-Flags AVP: Flags shall be set as follows:

– Single-Registration-Indication shall be set to 1 if a cancelSGSN indication was received within the ISR-Information within the eps-info within the UpdateGprsLocationArg; otherwise it shall be set to 0.

– S6a/S6d-Indicator shall be set to 1 if a servingNodeTypeIndicator was received within the UpdateGprsLocationArg; otherwise it shall be set to 0.

– Homogeneous Support of IMS Voice Over PS Sessions shall be set to 1 if an updateofHomogeneousSupportOfIMSVoiceOverPSSessions was received within the UpdateGprsLocationArg; otherwise it shall be set to 0.

– Removal of MME Registration for SMS shall be set to 1 if a removalofMMERegistrationforSMS was received within the UpdateGprsLocationArg; otherwise it shall be set to 0.

Context-Identifier AVP shall be present if contextId was received within pdn-gw-update parameter within eps-info within UpdateGprsLocationArg.

UE-SRVCC-Capability AVP shall be present if a ue-srvcc-Capability parameter was present in UpdateGprsLocationArg. If present the AVP shall be populated with the received ue-srvcc-Capability parameter.
