COMMUNICATION DEVICE, COMMUNICATION SYSTEM, AND HANDOVER METHOD

摘要

Provided is a communication device capable of reducing the network resource and the processing load of a network host. A handover destination performs unicast of packet data reporting an address of the handover destination to an upper-node device and the upper-node device reports release of connection with a communication terminal device to the handover origin. In this device, a handover control unit (104) judges whether a handover of the communication device to the local station is enabled according to the radio resource state of the local station. A message creation unit (105) creates a message containing an address of layer 2 of the local station as the handover destination, an address of layer 3 of the communication terminal device, and a unicast address for unicast to IPAG. An IPAG interface unit (106) performs unicast of the created message to the IPAG.
