Claim Text:
1. A method for controlling effective time of a terminal trigger message, comprising: receiving, by a mobility management unit, a terminal trigger message from a Machine Type Communication (MTC) application server; wherein the terminal trigger message comprises an effective time value of the terminal trigger message; in a scenario of congestion control, determining, by the mobility management unit, that a time value of a back-off timer is longer than the effective time value of the terminal trigger message, and reconfiguring the effective time value for the terminal trigger message; wherein when the mobility management unit rejects an Non-Access Stratum (NAS) request message initiated by a terminal which is under the congestion control, the back-off timer is carried in a rejection message such that the terminal cannot initiate any request until the back-off timer expires; wherein the reconfiguring, by the mobility management unit, the effective time value for the terminal trigger message comprises: reconfiguring the effective time value for the terminal trigger message such that the reconfigured effective time value of the trigger message is not less than the time value of the back-off timer.
