Abstract: The invention provides for path optimization for routing of a communication session in a network having a plurality of core networks coupled to a plurality of access networks. Both a core network and an access network perform the path optimization by determining a plurality of possible paths to a plurality of target access points to form a target matrix, determining a corresponding route preference factor for each possible path of the target matrix, and selecting, from the target matrix, a possible path having an optimal route preference factor. An overall or complete path, for routing of the communication session, is then determined either by combining the selected possible paths, or by selecting one possible path as a complete path.

Abstract: A method and apparatus for routing packet data in a communications system. The method includes receiving a first path packet at first node, the first path packet having a content, creating two packets having the content, sending the two packets via different paths to a second node, and creating an estimated packet including an estimate of the content in response to the two packets received at the second node. In addition, a method for providing soft handoff in a cellular communication system is provided, the method including receiving a first path packet at a first node, the first path packet having a content within the first node, creating two packets having the content, sending the two packets to a transmitter, transmitting the two packets via two different radio channels to a second node, and creating an estimated packet including an estimate of the content in response to the two packets received at the second node.

Abstract: 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.

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.

Abstract: 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.
