5 Mechanisms to handle SMS when there is more than one IP connection active with the UE, etc.
6 Mechanisms to handle MT-SMS without MSISDN to IMS UE, and SMS between IMS UEs that support MSISDN-less SMS operation.
The document also specifies the capabilities and enhancements needed to support the service level interworking for the Short Message service as defined in the TS 23.040  and in this specification and the Instant Messaging service as defined in OMA-TS-SIMPLE_IM-V1_
NOTE: The page-mode immediate message as defined in TS 24.247 is considered as a subset of OMA-TS-SIMPLE- IM-V1_0 .
The document also specifies the capabilities and enhancements needed to support service level interworking for the Short Message service, as defined in the TS 23.040  and in this specification and the OMA CPM service as defined in OMA-TS-CPM_Conv_Fnct
The service requirements are described in TS 22.340 .
