METHOD OF GROUP BASED MTC MESSAGING THROUGH CELL BROADCAST AND APPARATUSES USING THE SAME
First Claim
1. A method of transmitting a group trigger message to a group of Machine Type Communication (MTC) devices based on a Cell Broadcast Service (CBS) messaging system, adapted for a user equipment and the method comprises:
- receiving a paging message comprising an indicator;
receiving a broadcast message in response to receiving the paging message;
determining a resource from the broadcast message in which the group trigger message is located based on the indicator; and
obtaining the group trigger message from the resource of the broadcast message, wherein in response to receiving the indicator, the UE determines from the broadcast message the resource which is not a system information block (SIB) reserved for a warning message.

Abstract
The present disclosure proposes a method and apparatuses of implementing MTC group trigger messages through a Cell Broadcasting Service (CBS). The method includes a MTC (Machine Type Communication) server transmitting to a MTC Inter-working Function (MTC-IWF) a trigger payload. The trigger payload would be delivered by the MTC-IWF to a group of MTC devices through Cell Broadcasting Center (CBC) and network nodes. The trigger payload may include a group trigger message indicator which distinguishes the group trigger message from a normal warning message. In response to receiving the content of the trigger payload, the network would page a group of MTC devices. From the group trigger message indicator embedded in the paging message, each MTC device would be able to receive a group trigger message through new system information block of the broadcast information.

7. A method of transmitting a group trigger message to a group of Machine Type Communication (MTC) devices based on a Cell Broadcast Service (CBS) messaging system, adapted for a MTC inter-working function (MTC-IWF), and the method comprises:
-
receiving over a first interface a first message comprising a group identification (ID); generating from the first message a second message; and transmitting over a second interface to a Cell Broadcast Center (CBC) the second message comprising an information element which distinguishes the second message from a warning message, wherein the second interface is different from the first interface. - View Dependent Claims (8, 9, 10, 11)

12. A method of transmitting a group trigger message to a group of Machine Type Communication (MTC) devices based on a Cell Broadcast Service (CBS) messaging system, adapted for a base station and the method comprises:
-
receiving over a first interface a first message comprising an information element (IE) which indicates that the first message is intended for a group of MTC devices; transmitting a paging message comprising a group trigger message indicator which indicates a resource in a system information block (SIB) for the first message; and transmitting to the group of MTC devices over a cell broadcast channel a broadcast message comprising the first message which is embedded in the SIB of the broadcast message; wherein the SIB is different from another SIB reserved for a warning message. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
