Abstract
Provided are a group control method for providing a machine type communication (MTC) service, and a mobile communication system using the method. The group control method includes categorizing one or more MTC devices into one or more MTC groups, 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.
Claims10
A mobile communication system performing group control for a machine type communication (MTC) service, comprising:
- a mobility management entity (MME) configured to categorize one or more MTC devices into one or more MTC groups, and assign MTC group identifiers to respective MTC groups;
- and
- a base station configured to set MTC radio network temporary identifiers (MTC RNTIs) according to the MTC group identifiers, and use the MTC_RNTIs for addressing the MTC devices belonging to the respective MTC groups.
A base station communicating with a network and one or more machine type communication (MTC) devices, wherein MTC group identifiers are received from the network,
- MTC radio network temporary identifiers (RNTIs) are set according to the MTC group identifiers, and
- the MTC_RNTIs are used for addressing the MTC devices belonging to MTC groups,
- wherein an attach accept message including the MTC group identifiers is received from the network, the MTC_RNTIs are allocated to respective MTC group identifiers, and
- mapping information between the MTC group identifiers and the MTC_RNTIs is transmitted to the MTC devices.
