SMS Interworking between IMS UE without MSISDN and traditional UE
(e.g., CS) with MSISDN
1
Introduction(1/2)� Existing SMS infrastructure that an operator has in
place e.g. SC, GMSC-SMS, IWMSC is able to bereused. This is achieved by mandating MSISDN aspart of the SMS delivery addressing, even for SMSdelivery toward IMS.
� MTC allows the UE to have PS only subscriptionwithout MSISDN. Such UE may also be IMS UE.Allowing Messages delivery to these UEs in IMSwithout MSISDN is an important requirement forthese devices.
2
Introduction(2/2)� There is a need to improve the SMS submit/delivery
mechanism within IMS to allow MSISDN-less delivery toward the IMS registered UEs.
� IMS UEs without MSISDN that need to be investigated:� SMS Interworking between IMS UE without MSISDN
and traditional UE (e.g., CS) with MSISDN.
