APPARATUS AND METHOD TO EFFICIENTLY SEND DEVICE TRIGGER MESSAGES
First Claim
1. A Machine Type Communication Interworking Function (MTC-IWF) in a Long Term Evolution (LTE) network comprising:
- a processor arranged to;
receive a request to send a device trigger message via the LTE network;
validate the request to send a device trigger message;
request status information of a user equipment (UE) to which the device trigger message is to be sent;
receive the status information of the UE; and
send the device trigger message based on the status information;
whereinthe status information comprises information on a connection status of the UE.

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.

5. A method for sending a device trigger message to a destination user equipment (UE) in an LTE network comprising:
-
receiving a request to send a device trigger message; determining a priority of the device trigger message; transmitting the device trigger message if the priority of the device trigger message is high; if the priority of the device trigger message is low, checking if the destination UE for the device trigger message is in a connected state; sending the device trigger message when the destination UE is in a connected state; otherwise buffering the device trigger message until the destination UE is in a connected state. - View Dependent Claims (6, 7)
