  • Patent number: 5887256
    Abstract: A method for facilitating cellular communication for and among a plurality of native cellular handsets in a hybrid cellular communication network that has a cellular exchange subsystem and a private mobile-services switching center. In this embodiment, the cellular exchange subsystem is coupled to a public cellular , and the native cellular handsets represent handsets that subscribe to the hybrid cellular communication network. The hybrid cellular communication network further facilitates cellular communication between a nonnative cellular handset and the public cellular network, with the nonnative cellular handset being a cellular handset that does not subscribe to the hybrid cellular communication network. In this embodiment, the method includes the steps of receiving access request data, using a cellular exchange subsystem, and ascertaining whether the access request data originates from one of the plurality of native cellular handsets or from the nonnative cellular handset.

  • Patent number: 5842138
    Abstract: A configuration-independent software architecture for implementing a cellular communication network that facilitates communication among a plurality of cellular handsets. The architecture includes a first software functional block for implementing a first set of functions and a second software functional block for implementing a second set of functions. The architecture further includes a configuration-independent linkage block, which has an interface that appears consistent to both the first software functional block and the second software functional block irrespective of a relative position between the second software functional block, the first software functional block, and the configuration-independent linkage block in the cellular communication network. The configuration-independent linkage block facilitates communication between the first software functional block and the second software functional block via the interface utilizing configuration-independent linkage block.

  • Patent number: 5818824
    Abstract: A private multiplexing cellular network for facilitating cellular communication for private mobile stations (MS's), public MS's, and hybrid MS's. The private multiplexing cellular network includes a multiplexing circuit coupled to its radio subsystem. The multiplexing circuit is in turn coupled to two A-interfaces: a private A-interface for coupling the private radio subsystem with the private Mobile Switching Center (MSC), and a public A-interface for coupling the private radio subsystem with the public MSC. Intelligence is also provided with the multiplexing circuit to decide, based on a number of parameters, whether the public MSC or the private MSC should handle a given service request.

  • Patent number: 5781582
    Abstract: A base station communicates with a plurality of mobile stations over a cellular network. In one embodiment, the base station includes a receiver having a receiver synthesizer input, where the receiver is configured to receive inbound information from the mobile station on a first predetermined frequency. The receiver further has two programmable frequency sources that are configured to alternately supply a receiver synthesizer input signal to the receiver. The base station also includes a transmitter having a transmitter synthesizer input, where the transmitter is configured to transmit outbound information to the mobile station on a second predetermined frequency. The transmitter further has two programmable frequency sources that are configured to alternately supply a transmitter synthesizer input signal to the transmitter.

  • Patent number: 5761195
    Abstract: An apparatus for cross-connecting an end-to-end connection between an origination mobile station and a destination mobile station in a network of cross-connect nodes, which includes a call control circuit. The call control circuit includes a first circuit portion for receiving call control information from the origination mobile station and the destination mobile station and a second circuit portion for determining, responsive to receiving the call control information from the origination mobile station and the destination mobile station, an optimum end-to-end connection for cross-connecting the end-to-end connection through the network of cross-connect nodes. The optimum end-to-end connection represents a computed shortest communication route between the origination mobile station and the destination mobile station that satisfies resource requirements for cross-connecting the end-to-end connection.

  • Patent number: 5734979
    Abstract: A base station communicates with a plurality of mobile stations over a cellular network. In one embodiment, the base station includes a transceiver configured to receive inbound information from the mobile station and transmit outbound information to the mobile station. The transceiver equalizes and decodes the inbound information and encodes the outbound information. The transceiver is coupled to a data bus for communicating the inbound and outbound information with the other elements in the base station. The transceiver is also coupled to a control bus. An trunk module is coupled to the data bus and to a mobile services center. The trunk module communicates inbound and outbound information with the mobile services center. The trunk module is also coupled to the control bus. Finally, a central processor is coupled to the control bus to control the transceiver and the trunk module. A preferred protocol is Global Systems for Mobile Communication (GSM).

  • Patent number: 5734699
    Abstract: A cellular private branch exchange for facilitating cellular communication for a first plurality of mobile station units, which includes a first base station subsystem for communicating with a first and a second mobile station unit of the first plurality of mobile station units on respectively a first and a second cellular bearer data channel. The cellular private branch exchange further includes a cellular private branch exchange unit coupled to the first base station subsystem. In turn, the cellular private branch exchange unit includes a private mobile-services switching center for providing mobility management for the first plurality of mobile station units, the private mobile-services switching center representing a first cross-connect node capable of cross-connecting the first bearer data channel with the second bearer data channel for calls between the first and the second mobile station units.
