Abstract:
A method and apparatus for small packet transmission in response to machine type communication (MTC) device trigger indication are provided. For uplink (UL) transmission of small packet from MTC device in idle state, a tracking area update (TAU) complete non-access stratum (NAS) message is used to protect integrity and confidentiality of UL small packet transmission without attach/service request procedure during idle state. For downlink (DL) transmission of small packet from MTC device in idle state, a TAU accept NAS message is used to protect integrity & confidentiality of DL small packet reception without attach/service request procedure during idle state.
