Method of Realizing Mobile Communication Packet Data Network in the Non-ATM Backbone Network

摘要

A packet data network for providing a radio packet data service in a mobile radio communication system. The packet data network includes a plurality of radio network controllers (RNCs) for controlling a radio channel allocation to a mobile station and for controlling, matching the network, a path of a packet data service or a circuit data service; a plurality of packet data gateway nodes (PDGNs) for performing management of a mobility of the mobile station and a routing function of packet data for information management; a mobile switching center (MSC) for registering and managing terminal node identifiers of the RNCs and the PDGNs connected to the mobile switching center, and for managing and giving to the PDGNs network identification addresses which a user can directly call; and a packet router for providing a packet data transmission path by routing a packet data between the RNC and PDGN, if a mobile station requests the packet data service. If the mobile station requests the packet data service, a packet router is provided a packet transmission path in association with the RNCs, PDGNs, and MSC or another MSC.
