Abstract

With the proliferation of Machine-Type Communication (MTC), an excessive use of device trigger messages in a Long Term Evolution (LTE) network can have negative effects on user equipment (UE). These effect can include a shortening of UE battery life and/or excessive signalling caused by the frequent changing from an idle mode to an active mode. An MTC Interworking Function (MTC-IWF) can be configured to determine the status of a UE to which a device trigger message is intended. If the device trigger message is low priority and the UE is in an idle state, the MTC-IWF or Mobile Management Entity (MME)/Serving GPRS Support Node (SGSN)/Mobile Switching Center (MSC) can buffer the device trigger message.

Claims

1. A user equipment (UE) comprising:

transceiver circuitry configured to;

receive triggering information that includes an Application Port ID; and

processor circuitry in the UE to;

route a trigger message to a triggering function using the Application Port ID, wherein the trigger message further includes a standardized identifier, and wherein the circuitry is further arranged to distinguish messages carrying device triggering information based on the standardized identifier identify an Application Port ID based on a message, wherein a payload of the trigger message includes a priority value to indicate the priority of the trigger message and, when the priority of the trigger message is low, the UE is to receive the trigger message when the UE is in a connected state and not receive the trigger message when the UE is in an idle state.

2. The UE of claim 1, wherein the UE is configured to perform machine-type communications (MTC).

3. The UE of claim 1, further including:

two or more antennas.

4. The UE of claim 1, further including:

file storage memory.

5. A Machine Type Communication Interworking Function (MTC-IWF) comprising:

processing circuitry to

receive a device trigger request, from a Services Capability Server (SCS), that includes an Application Port ID, wherein a trigger payload corresponding to the device trigger request includes a priority value to indicate priority of the trigger request; and

forward a standardized identifier to the UE to allow the UE to distinguish machine-type messages carrying device triggering information, wherein the MTC-IWF is further arranged to,

when the priority of the device trigger request is low,

send the device trigger message when the UE is in a connected state; and

buffer the device trigger message when the UE is in an idle state.

6. A non-transitory computer-readable medium including instructions that, when executed on a machine, cause the machine to:

receive a message including a device trigger request that includes an Application Port wherein a trigger payload corresponding to the device trigger request includes a priority value to indicate priority of the trigger request; and

forward a standardized identifier to the UE to allow the UE to distinguish machine-type messages carrying device triggering information, wherein the instructions further cause the machine to, when the priority of the device trigger request is low,

send the device trigger message when the UE is in a connected state; and

buffer the device trigger message when the UE is in an idle state.

7. The non-transitory computer-readable medium of claim 6, wherein the machine includes a Machine Type Communications Interworking Function (MTC-IWF), and wherein the request is received from a Services Capability Server (SCS).

8. The non-transitory computer-readable medium of claim 6 wherein the machine is a mobile management entity (MME).
