The Short Message Service (SMS) has have enjoyed great success in cellular networks. At the same time, specifications have been and are being developed for extending 3GPP services to non-cellular IP Connectivity Access Networks (IPCANs). In this same spirit, this specification describes the capabilities needed to support SMS for generic IP-CANs.
SMS over generic IP access can be used to support applications and services that use SMS when a generic IP access is used.
This TS specifies the new capabilities and enhancements needed to support SMS over a generic IP
Connectivity Access Network (IP-CAN) using IMS capabilities (TS 23.228
). These include (but are not limited) to:
Enhancements to the HSS;
Communication between the SMS-GMSC/SMS-IWMSC and the HSS;
Authentication of service usage and registration;
Transfer of UE Terminated SMS, UE Originated SMS, and Delivery reports;
Mechanisms to handle SMS when there is more than one IP connection active with the UE, etc.
Mechanisms to handle MT-SMS without MSISDN.
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_0. The features supported from the IM specification are limited to the
exchange of short or large immediate messages in pager mode.
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-V1_0. The features supported from the CPM specification are the exchange of short
or large immediate messages in pager mode, as well as session-based messaging.
The service requirements are described in TS 22.340
