Abstract
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).
