GROUP CONTROL METHOD FOR MACHINE TYPE COMMUNICATION AND MOBILE COMMUNICATION SYSTEM USING THE METHOD
First Claim
1. A group control method for providing a machine type communication (MTC) service in a mobile communication network including a mobility management entity (MME), a base station, and one or more MTC devices, the method comprising:
- categorizing one or more MTC devices into one or more MTC groups, and assigning MTC group identifiers to respective MTC groups;
setting MTC radio network temporary identifiers (MTC_RNTIs) according to the MTC group identifiers; and
using the MTC_RNTIs for addressing the MTC devices belonging to the respective MTC groups.
