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).

Claims

1. A SCS (Service Capability Server) for a mobile communication system, the SCS comprising:

a transmitter configured to send, to a MTC-IWF (MTC-Inter Work Function), a trigger message which includes a trigger type showing plural different device trigger systems; and

a controller configured to trigger a UE (User Equipment) based on the trigger type after receiving an authorization by the MTC-IWF.

2. The SCS server of claim 1, wherein the MTC-IWF blocks the trigger message from an unauthorized server.

3. A method of a SCS (Service Capability Server) for a mobile communication system, the method comprising:

sending, to a MTC-IWF (MTC-Inter Working Function), a trigger message which includes a trigger type showing plural different device trigger systems; and

triggering a UE (User Equipment) based on the trigger type after receiving an authorization by the MTC-IWF.

4. A MTC-IWF (MTC-Inter Work Function) for a mobile communication system, the MTC-IWF comprising:

a receiver configured to receive, from a SCS (Service Capability Server), a trigger message which includes a trigger type showing plural different device trigger systems; and

a controller configured to authorize the SCS to trigger a UE (User Equipment) based on the trigger.

5. The MTC-IWF network node of claim 4, wherein the MTC-IWF blocks the trigger message from an unauthorized server.

6. A method of a MTC-IWF (MTC-Inter Work Function) for a mobile communication system, the method comprising:

receiving, from a SCS (Service Capability Server), a trigger message which includes a trigger type showing plural different device trigger systems; and

authorizing the SCS to trigger a UE (User Equipment) based on the trigger type.

7. A UE (User Equipment) for a mobile communication system), the UE comprising:

a receiver configured to receive a trigger from an authorized SCS (Service Capability Server) that sends a trigger message which includes a trigger type showing plural different device trigger systems to a MTC-IWF (MTC-Inter Work Function); and

a controller configured to verify the received trigger and take specific actions in response to the reception of the trigger.

8. The UE of claim 7, wherein the MTC-IWF blocks the trigger message from an unauthorized server.

9. A method of a UE (User Equipment) for a mobile communication system), the method comprising:

receiving a trigger from an authorized SCS (Service Capability Server) that sends a trigger message which includes a trigger type showing plural different device trigger systems to a MTC-IWF (MTC-Inter Work Function); and

acting in response to the reception of the trigger.
