METHOD FOR PROCESSING OF PACKET SERVICE AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To guarantee a sufficiently high achievement rate for packet data transmission by sending back a packet data address for recipient device discrimination in response to an inquiry for transmission to/from a moving body communication device through a radio interface of an access communication network. SOLUTION: An access repeating device GMSC allows access for connections with a packet base type core communication network IPCNW or a switching device ROU which arrives from one of line switching networks and is started by a terminal device T. At this time, the mapping of a subscriber calling number E164 to a packet data address IPAD or its reverse mapping are carried out similarly to a control node EN. This access repeating device GMSC supports the H.323 protocol for packet data signaling and the packet transport protocol of a connection path.
