FRAME STRUCTURE DESIGN FOR NEW CARRIER TYPE (NCT)

摘要

Technology for communicating a short message service (SMS) communication in a packet switched (PS) domain of a serving general packet radio service (GPRS) support node SGSN in a Universal Terrestrial Radio Access Network (UTRAN). One method comprises receiving, at the SGSN, 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 SGSN.
