US 2010/0062772 A1 · METHOD, WIRELESS COMMUNICATION SYSTEM, AND GROUP MOBILITY CONTROLLER FOR PROCESSING GROUP MOBILITY

Abstract

A method, a wireless communication system, and a group mobility controller (GMC) for processing group mobility are provided by the exemplary embodiments of the present invention. In the method, a fixed GMC paging group identifier (PG-ID) is assigned to the GMC when the GMC starts up a group mobility function; and a target network obtains group information of the GMC, and updates a PG-ID list of the target network with the group information of the GMC during a message interaction process when the GMC hands over from a serving network to the target network, and then utilizes the updated PG-ID list during a subsequent interaction process with a group node. The system includes a GMC, a serving network, and a target network. The signaling storm raised when numbers of terminals in an idle mode perform location update at the same time during the group mobility can be avoided according to the above technical solutions, thereby realizing the economy of air interface resources and signaling overheads.

Dependent claims

A method for processing group mobility, wherein a fixed group mobility controller (GMC) paging group identifier (GMC PG-ID) is assigned to a GMC when the GMC starts up a group mobility function, the method further comprising:

obtaining, by a target network, group information of the GMC;
and
updating, by the target network, a PG-ID list of the target network using the group information of the GMC during a message interaction between a serving network and the target network while the GMC handing over from the serving network to the target network.

A wireless telecommunication system, comprising:

a group mobility controller (GMC), a serving network and a target network;
wherein
the GMC comprises a group mobility function module, which is adapted to start up a group mobility function and obtain a fixed GMC paging group identifier (GMC PG-ID);
the target network comprises a group information obtaining module and a first storage module;
wherein
the group information obtaining module is adapted to obtain group information of the GMC during a message interaction between the serving network and the target network while the GMC handing over from the serving network to the target network, and notify the first storage module to update a PG-ID list stored in the first storage module using the group information of the GMC.
