Patent ID: 8909265

Claim:
A method for processing validity time in trigger information, comprising: a machine type communication (MTC) server sending the trigger information including the validity time (VT) to a network edge entity; the network edge entity setting a validity period (VP) of the trigger information in a short message service (SMS) according to the VT in the received trigger information; and the network edge entity forwarding the trigger information to a user equipment through a network node in the VP; wherein, the step of the network edge entity setting a VP of the trigger information in a SMS according to the VT in the received trigger information is: the network edge entity storing a time of receiving the trigger information, and mapping a VT value in the received trigger information to a VP value of the trigger information in the SMS; the network edge entity is a service center (SC), or a MTC interworking function (MTC-IWF); wherein, the step of forwarding the trigger information to a user equipment through a network node in the VP is: after confirming that the trigger information is in the VP in the SMS, the network edge entity sending the trigger information in form of short message to a network node that the SMS passes, and the network node forwarding the trigger information to the user equipment; after confirming that the trigger information is not in the VP in the SMS, the network edge entity deleting the trigger information, and sending a sending failure indication of the trigger information to the MTC server.
