Abstract
Abstract A localized wireless gateway system provides wireless telephone communication, and for at least interexchange communication, provides voice telephone access to a public packet data network, such as the Internet. The wireless gateway system includes base station transceivers and a packet service gateway coupling the transceivers to the public packet data network. The packet service gateway compresses and decompresses voice frequency communication signals, and it sends and receives the compressed signals in packet form via the network. The packet service gateway also provides for signaling through the network to establish two-way voice communication sessions. In the preferred implementation, the localized wireless gateway system includes at least one radio port control unit coupled to the base station transceivers for controlling calls through the transceivers. The localized wireless gateway system also includes a telephone switch, such as a digital PBX, selectively providing telephone communication channels between the radio port control unit(s) and the packet service gateway. An access manager controls registration and validation of roaming wireless telephones to utilize the wireless gateway system. The access manager also transmits location information for registered wireless telephones to a home location register database via the network. The communications of the access manager to the home location register database permit telephone authentication as well as maintenance of accurate location information in the home location register identifying the current gateway through which a caller can reach the roaming user's wireless telephone.
