Abstract

A mobile communication system transfers a packet to a mobile communication terminal forming an adhoc network, through a core network, based on address information of the mobile communication terminal. The address information of the mobile communication terminal includes common information which is changed when a connection point between the adhoc network and the core network is changed, and individual information which is maintained unchanged even when the connection point between the adhoc network and the core network is changed. The packet is configured to be transferred based on the individual information in a communication within the adhoc network.

Claims

1. A mobile communication system which transfers a packet to a mobile communication terminal forming an adhoc network, through a core network, based on address information of the mobile communication terminal, wherein

the address information of the mobile communication terminal includes common information which is changed when a connection point between the adhoc network and the core network is changed, and individual information which is maintained unchanged even when the connection point between the adhoc network and the core network is changed;

and

the packet is configured to be transferred based on the individual information in a communication within the adhoc network.

2. A mobile communication terminal which is capable of forming an adhoc network, comprising:

an address information management unit configued to manage address information including common information which is changed when a connection point between the adhoc network and a core network is changed, and individual information which is maintained unchanged even when the connection point between the adhoc network and the core network is changed;

a core network communication unit configured to transfer a packet, based on the address information, in a communication through the core network; and

an adhoc network communication unit configured to transfer a packet, based on the individual information, in a communication within the adhoc network.
