Abstract:
A method for allowing a mobile station to communicate in a wireless communication system, the wireless communication system comprising a plurality of private base transceiver stations, the private base transceiver stations having radio transceivers that communicate data and signaling information with the mobile station, the private base transceiver stations also having a processing layer for mobility management and a call control processing layer contained within them, the private base transceiver stations interconnected by a packet data network, the method comprising the steps of:receiving a call control message at the private base transceiver stations and passing the call control message to the processing layer for mobility management resident within the private base transceiver stations, without forwarding the call control message to a base station controller, the call control message including a control function identifier and a mobile station identifier; forwarding the call control message internally within the private base transceiver stations to a packet interface layer in the private base transceiver stations, the packet interface layer providing communication between the private base transceiver stations and other nodes connected to the packet data network; at the packet interface layer, formatting an external control message intended for transmission over the packet data network, the formatted external control message indicating an alias identifier corresponding to the mobile station identifier; and forwarding the formatted external control message across the packet data network.
