Secure method for MTC device triggering
First Claim
1. A communication system comprising:
- a terminal used for MTC (Machine-Type Communications);
an SCS (Service Capability Server) configured to send a trigger message; and
an MTC-IWF (Machine-Type Communications Inter-Working Function) including one or more processors configured to check whether the SCS is authorized to send the trigger message,wherein if the check fails, the MTC-IWF blocks the trigger message, andwherein if the check passes, the terminal receives the trigger message.

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).

9. A terminal used for MTC (Machine-Type Communications), the terminal comprising:
-
a transceiver configured to receive a trigger message, if an MTC-IWF (Machine-Type Communications Inter-Working Function) checks whether an SCS (Service Capability Server) is authorized to send the trigger message and the check passes, wherein, if the check fails, the trigger message is blocked by the MTC-IWF. - View Dependent Claims (10, 11, 12)

13. A communication method in a communication system including a terminal, an SCS (Service Capability Server), and an MTC-IWF (Machine-Type Communications Inter-Working Function), the communication method comprising:
-
checking, by the MTC-IWF, whether the SCS is authorized to send a trigger message; if the check fails, blocking, by the MTC-IWF, the trigger message; and if the check passes, receiving, by the terminal, the trigger message. - View Dependent Claims (14, 15, 16)

17. A method for use in a terminal used for MTC (Machine-Type Communications), the method comprising:
-
receiving a trigger message, if an MTC-IWF (Machine-Type Communications Inter-Working Function) checks whether an SCS (Service Capability Server) is authorized to send the trigger message and the check passes, wherein, if the check fails, the trigger message is blocked by the MTC-IWF. - View Dependent Claims (18, 19, 20)
