摘要： A method of improving the reliability of peer-to-peer network downloads includes the steps of initiating a search from a client on a peer-to-peer network (152). Next, a list of servers is downloaded that satisfies the search (154). At least one of the server is selected from the list of servers (156). Next, one of a plurality of downloading systems is selected based on a predetermined criteria (158). A file is downloaded using one of the plurality of downloading systems.

摘要： A mobile station (68) is provided with intelligent roaming capabilities. The mobile station, which may be implemented as a mobile, cellular, or PCS telephone unit, includes a System Access List (SAL) that is stored in a memory (67) of the mobile station (68). The SAL may be programmed into the mobile station through a physical interface (such as a computer interface) or by using an over-the-air programming function. When the mobile station (68) is initialized, the mobile station first scans the bands of its home system (54). A secondary band may also be provided for scanning, if the mobile station is unable to locate a control channel on its home band. If the mobile station is not located within its home system, the SAL is searched to determine whether the current system is a preferred system (58). The SAL may include information on the blocks of channels to scan in the preferred bands.

摘要： A desired signal (C(t)) and at least one interfering signal (I(t)) are joint demodulated with a Viterbi equalizer (20) having an adaptive total number of states. The total number of states is based on channel impulse response (CIR) coefficients associated with the desired signal (C(t)) and the at least one interfering signal (I(t)).

摘要： An Asynchronous Transfer Mode (ATM)-based distributed network switching system includes an ATM switching network (26) that dynamically sets up individual switched virtual connections. The system also includes multiple access interworking function (A-IWF) devices each operating as a gateway that enables customer premises devices to directly interface into the distributed ATM switching fabric. The system further includes a centralized control and signaling interworking function (CS-IWF) device that performs call control functions and adminstrative functions and is adapted to interface narrowband and broadband signaling for call processing and control within the ATM switching network (26). The CS-IWF device (30) may be a server farm.

摘要： Method and apparatus for a distributed switching system supporting a plurality of services. A service request is initiated by an initiating customer. The service request is then executed using, for example, a user-to-network interface setup. A terminating setup is then performed to either accept or reject the requested service. Multiple service requests are correlated with respective services to enable at least one appropriate policy and logic. Data related to the requested service is obtained using at least one of a push procedure, a pull procedure, a query procedure, and a procedure in which requests are associated with the issuance of certificates.
