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 system for an MTC (Machine-Type-Communication), comprising:

an MTC device;

a network that includes an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center), and an MTC-IWF (MTC-Inter Working Function); and

an SCS (Service Capability Server);

wherein the SCS sends a trigger message including information, which indicates whether the trigger message is delivered to the MTC device even when detached, to the network; and

the MTC device is triggered by the network based on the information.

2. A method of a system for an MTC (Machine-Type-Communication) including an MTC device, an SCS (Service Capability Server) and a network that includes an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center), and an MTC-IWF (MTC-Inter Working Function), comprising:

sending, by the SCS, a trigger message including information, which indicates whether the trigger message is delivered to the MTC device even when detached, to the network; and

triggering, by the network, the MTC device based on the information.

3. A network in a system for an MTC (Machine-Type-Communication), comprising:

an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center); and

an MTC-IWF (MTC-Inter Working Function);

wherein the network receives a trigger message including information, which indicates whether the trigger message is delivered to an MTC device even when detached, from an SCS (Service Capability Server); and

the network triggers the MTC device based on the information.

4. A method of a network in a system for an MTC (Machine-Type-Communication) including an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center), and an MTC-IWF (MTC-Inter Working Function), comprising;

receiving a trigger message including information, which indicates whether the trigger message is delivered to an MTC device even when detached, from an SCS (Service Capability Server); and

triggering the MTC device based on the information.

5. An MTC (Machine-Type-Communication) device in a system for the MTC including an SCS (Service Capability Server) and a network that includes an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center), and an MTC-IWF (MTC-Inter Working Function), comprising:

a controller configured to adapt a power saving for reducing power consumption of the MTC device; and

a receiver to being triggered by the network,

wherein the SCS sends a trigger message including information, which indicates whether the trigger message is delivered to the MTC device even when detached, to the network, and

the MTC device is triggered by the network based on the information.

6. A method of an MTC (Machine-Type-Communication) device in a system for the MTC including an SCS (Service Capability Server) and a network that includes an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node) or an MSC (Mobile Switching Center), and an MTC-IWF (MTC-Inter Working Function), comprising:

adapting a power saving for reducing power consumption of the MTC device; and

being triggered by the network,

wherein the SCS sends a trigger message including information, which indicates whether the trigger message is delivered to the MTC device even when detached, to the network, and

the MTC device is triggered by the network based on the information.
