Method and device for device trigger/small data exchange/collection in wireless communication system

摘要

According to one embodiment of the present invention, a method for exchanging/collecting a device trigger by a short message service-service center (SMS-SC) in a wireless communication system comprises the steps of: receiving a first message including an old trigger reference number from a machine type communications-interworking function (MTC-IWF); and deleting a trigger message corresponding to the old trigger reference number, wherein when the first message further includes a new trigger reference number, the SMS-SC detects the trigger message and stores a new trigger message corresponding to the new trigger reference number.
