Architecture of mobile communication systems network and method for transmitting packet data using the same

Abstract

Architecture of a mobile communication system network and method for transmitting a packet data using the same, which can minimize required signal links and interlocking lines, the architecture including a plurality of radio network controllers each connected to a plurality of base stations in a cell or a sector to which the network controller pertains for separating a packet data service path from a circuit data service path when a particular mobile station is matched to this core network, at least one mobile switching center connected to the plurality of radio network controllers in a region of the mobile switching center by an ATM switching system for routing an originating call from the mobile station or a terminating call to the mobile station, a VLR/HLR(Visitor location register/home location register) connected to the mobile switching center for managing mobility of the mobile stations, and at least one PDGN(Packet data gateway node) for routing a packet data provided from either the mobile switching center or an external network according to a terminating call side identification number.
