Abstract
Upon receiving a triggering message from a MTC server (20), a network (10) verifies if the MTC server (20) is authorized to trigger a target MTC device (30) and also if the MTC device (30) is authorized to respond the triggering message, by comparing an MTC device ID and MTC server ID (and optionally information on subscription) which are include in the triggering message with authorized ones. Upon succeeding in the verification, the network (10) checks a trigger type included in the triggering message to verify if the triggering message is authorized to be sent to the MTC device (30). Upon succeeding in the check, the network (10) forwards the triggering message to the MTC device (30). The network (10) also validates a response from the MTC device (30), by checking whether the MTC device (30) is allowed to communicate with the addressed. MTC server (20).
