Method and device for triggering machine-type communication MTC in wireless communication system

摘要

The present invention relates to a method for enabling a MTC (machine type communication) IWF (interworking function) to perform a trigger request in a wireless communication system. The method includes transferring, to a first serving node, the trigger request and information related to retrying the trigger request which includes information on whether to retry if the transferring of the trigger request fails, wherein if the information on whether to retry indicates retrying, the retrying of the trigger request is assigned to the first serving node.

1. A method of performing a MTC (machine type communication) trigger request, which is performed by a MTC-IWF (interworking function) in a wireless communication system, comprising:
transmitting the trigger request and first information about a retry of the trigger request to a first serving node, wherein the first information comprises information on whether to perform the retry when a delivery of the trigger request by the first serving node fails, and wherein, if the first information indicates to perform the retry, the first information configures the first serving node to retry the delivery of the trigger request based on the first information when the delivery of the trigger request fails, wherein, if the first information indicates not to perform the retry, the first information configures the first serving node to transmit a delivery report message indicating a failure of delivering the trigger request by the first node to the MTC-IWF without retrying the delivery of the trigger request, and wherein the first information further comprises at least one of a number of the retry and validity time of the retry for the first serving node.
