SHORT MESSAGE SERVICE IN PROSE

摘要

Methods and systems are disclosed for delivering SMS messages while reducing the signaling overhead within a cellular CN. For example, an SMS originating WTRU may send an indication to a RAN entity, and the indication may indicate that an SMS recipient WTRU is in the same relative geographical area as the originating WTRU. The originating WTRU may send the SMS message to the RAN entity. The SMS message may indicate that the recipient WTRU is an intended destination of the SMS message. Methods and systems are disclosed for an SMS anchor node to deliver an SMS message. For example, the SMS anchor node may receive an indication that a WTRU is in the same general geographical area as a originating WTRU. The SMS anchor node may deliver the SMS message to the recipient WTRU without utilizing a SMS Service Center SC to route the SMS message.
