System and method for processing trigger messages of a terminal

摘要

A method and system for processing trigger message of a terminal, wherein, the method includes: after receiving trigger message which is transmitted from a machine type communication server to the terminal, a control network element in a core network storing the trigger message of the terminal, and removing the trigger message of the terminal before a validity timer for the trigger message of the terminal expires. The control network element in the present scheme removes the stored trigger message in time before the validity timer for the trigger message of the terminal expires, thus saving the storage resources of the network.

1. A method for processing a trigger message of a terminal, comprising:
a control network element in a core network storing the trigger message of the terminal after receiving the trigger message which is transmitted by a machine type communication server to the terminal, and removing the trigger message of the terminal before a validity timer for the trigger message of the terminal expires; wherein, the step of the control network element removing the trigger message of the terminal before a validity timer for the trigger message of the terminal expires comprises: when determining that a mobile reachable timer expires, the control network element starting an implicit detach timer, and when determining that the implicit detach timer expires and the validity timer for the trigger message of the terminal does not expire, the control network element removing the trigger message of the terminal, so that the implicit detach timer is combined with the mobile reachable timer and the validity timer together to trigger the operation of removing the trigger message of the terminal.
