SHORT MESSAGE SERVICE (SMS) COMMUNICATION IN WIRELESS NETWORKS IN THE PACKET SWITCHED DOMAIN

摘要

Technology for communicating a short message service (SMS) communication in a packet switched (PS) domain of an evolved packet system (EPS) network. One method comprises receiving, at a core network (CN) control node, a request message from a user equipment (UE) indicating that the UE supports PS based SMS and performs a circuit switched (CS) registration only to receive SMS service via a CS domain; and sending, from the CN control node, an accept message to the UE indicating that SMS over a non-access stratum (NAS) is supported by the CN control node.
