摘要： A base station system (BSS) encompasses a base station controller (BSC), ATM transcoder (AXC), and one or more Base Tranceiver Subsystems (BTS). The AXC provides for the coupling of external mobile subscriber subsystems (MS) and a public switched telephone network (PSTN). The BSC provides for communication with and control of the ATM transcoder hub subsystem. In one embodiment, the ATM transcoder subsystem provides a first set of signals to the BSC subsystem to signal the base station controller as to call flow management data. The BSC is responsive to the first set of signals from the ATM transcoder hub to generate a second set of signals coupled back to the ATM transcoder hub. This second set of signals provides for the control of transcoding and conversion necessary to communicate between a wireless air communications format data and a call management protocol format data utilized in communication to the public switch telephone network. In one embodiment, the communication between the PSTN and the AXC is in an ATM format and in an alternate embodiment a synchronous format is used. The BSC provides control and sequencing of all call control operations. Control is preferably near real-time. In one embodiment, call control operations comprise call setup, breakdown, and hand-off among the ATM transcoder hub (AXC), the Base Transceiver Subsystem (BTS), and the PSTN via a Mobile Switching Center (MSC).

摘要： An ATM hub transcoder system (AXC) is coupled to a base station controller (BSC), a mobile switching center (MSC), and a base transceiver subsystem (BTS). In one embodiment, the transcoder system is comprised of an ATM switch subsystem, a transcoder subsystem (XC), a base transceiver subsystem interface (BTSI), and a mobile switching center network interface subsystem (MSC-NI). The ATM switch provides coupling and communication of data in an internal ATM format between each of the XC, BTSI, MSC-NI, and BSC, responsive to control signals from the BSC. The MSC-NI provides for conversion of the format of the data between the internal ATM format and a synchronous format. In one embodiment, the synchronous format is used for communication between the MSC and the NI, responsive to the MSC and the BSC, and the BTSI provides for communicating mobile subsystem information between the BTS and the XC, responsive to the BTS and the BSC. In one embodiment, the interface between the ATM switch and the MSC-NI is PCM encoded in the internal ATM format data. The In an alternate embodiment, the interface between the ATM switch and the BTSI is of digitally encoded voice data in the internal ATM format. The MSC-NI couples the data originating from the MSC via the ATM switch to the transcoder subsystem (XC).

摘要： A network interface (NI) system provides for communicating encoded digital data between a connection-based network and a plurality of cellular communications networks. Each of the cellular communications networks is comprised of a plurality of cell sites that communicate with a plurality of mobile units via radio signals. The cell sites provide for converting data received in said radio signals (e.g., embedded data) into electronic digital data signals and converting the electronic data signals into radio signals. The connection-based network has a plurality of delivery points which function to translate from the electronic data into a form used by said connection-based network and from the form used by said connection-based network into the electronic data. The network interface system is comprised of a base transceiver subsystem (BTS), a base station controller (BSC), a Base Station Transceiver Subsystem Interface (BTSI), a transcoder (XC), an operations maintenance and control subsystem (OMC), and an ATM switch providing for communications of the electronic data as packetized ATM cells between the BTSI, NI, XC, and the BSC. The BTSI is coupled to each of the cell sites and to the ATM switch. The BTSI provides for packetizing the electronic data as ATM cells for transmission by the ATM switch, for transmitting and receiving the packetized ATM cells communications with said ATM switch, and for depacketizing the electronic data responsive to the received ATM cells from the ATM switch.
