Method and apparatus for controlling access to machine-type communication device having dual priority application

摘要

A method for controlling access to a machine-type communication (MTC) device having a dual priority application in a mobile communication network. More particularly, a signaling method executed in a terminal configured to perform non-access stratum (NAS) signaling including low access priority indication in a mobile communication network and configured such that the low access priority is negligible. The signaling method may include performing one of a procedure of mobility management and a session management including the low access priority, receiving a back-off timer due to one of mobility management congestion control and session management congestion control and operating the back-off timer, and performing one of the mobility management procedure and the session management procedure without including the low access priority.

1. A signaling method executed by a User Equipment (UE) configured to perform Non-Access Stratum (NAS) signaling including a low access priority indication and configured that a low access priority can be overridden, the signaling method comprising:
performing a session management procedure including the low access priority; receiving a timer value for a session management back-off timer due to a session management congestion control, and operating the session management back-off timer with the timer value; and performing the session management procedure without including the low access priority while the session management back-off timer is running; wherein the performing of the session management procedure including the low access priority includes configuring a radio resource control (RRC) connection establishment cause of an eNodeB as “delay tolerant”; and wherein the performing of the session management procedure without including the low access priority includes configuring the RRC connection establishment cause of the eNodeB as “mobile originated (MO) signaling” or “MO data”.
