摘要： Multicast data in a wireless network is encoded with FEC codes where K information symbols are encoded into N transmission symbols, N > K, where K-N represents redundancy, such that reception and decoding of any K+A transmission symbols is sufficient to recover the K information symbols, where A is small relative to K. The level of redundancy may be selected to provide adequate performance to a mobile terminal at the edge of a cell, or to the mobile terminal reporting the lowest quality link. Upon handoff, a mobile terminal may be directed to an ongoing multicast in the new cell of the same information, or alternatively the new cell may transmit only the multicast packets the mobile terminal has not received. Different time segments of the information may be separately encoded, or the same information encoded with different level of redundancy, and the encoded data transmitted on different wireless channels.

摘要： A telecommunications system and method is disclosed for determining the address of both the home and serving Mobile Positioning Centers (MPCs). Each Mobile Switching Center/Visitor Location Register (MSC/VLR) and Home Location Register (HLR) within a Public Land Mobile Network (PLMN) will be provided with the MPC address that is valid for its PLMN. When a Mobile Station (MS) roams into a new (serving) PLMN, a Location Update is performed by the serving MSC/VLR to the Home Location Register (HLR). The MPC address for the serving MSC/VLR will be included in every location update operation to the HLR, which can then store this serving MPC address in the subscriber's HLR record. Furthermore, the home MPC address, valid for the PLMN of the HLR, is included in every subscriber data transfer operation from the HLR to the serving MSC/VLR, which can then store this home MPC address, in the subscriber's VLR record.

摘要： A method for responding to a pointer received on an analog control channel pointing to a control channel belonging to a forbidden service provider includes avoiding a power-up scan and resuming camping on the analog control channel. A wireless communications mobile unit is camped on an analog control channel may receive a channel pointer to a digital control channel. If the digital control channel has acceptable received signal strength, the service provider information for that control channel is checked. If the control channel belongs to a non-forbidden service provider, the mobile unit camps on the digital control channel. If the control channel belongs to a forbidden service provider, the mobile unit returns to camping on the analog control channel without performing an intervening power-up scan. By avoiding power-up scans when the pointed-to channel belongs to a forbidden service provider, less power is consumed and users receive more consistent communications service.

摘要： The present invention provides a method, apparatus and system for providing multimedia messages to incompatible terminals. The apparatus includes a notification module (216), a media converter (220) and a retrieval module (218). The notification module (216) notifies the incompatible terminal (210) that the multimedia message (222) is available. The media converter (220) transcodes one or more parts of the multimedia message (222). The retrieval module (218) is communicably coupled to the media converter (220) and retrieves the multimedia message (222) in response to a delivery request (232, 234) from the incompatible terminal (210), renders the multimedia message (222), using the media converter (220) as necessary, into a message that is compatible with the incompatible terminal (210) and sends the message to the incompatible terminal (210). This method can be implemented using a computer program embodied on a computer readable medium wherein each function is executed using a code segment.

摘要： An Automatic Frequency Control (AFC) circuit for a mobile terminal employs a fractional-N Phase Locked Loop (PLL) to directly reduce errors in the synthesized frequency, such as due to component tolerances, temperature drift, and the like. The frequency error is detected by the average speed of rotation of the I,Q constellation. A corresponding offset is added to the tuning frequency selection word prior to encoding, such as in a ΔΣ modulator, to generate an effective non-integer PLL frequency division factor over a specified duration. The ΔΣ modulator may include dithering the different integer values by a pseudo-random number to minimize noise in the output frequency spectrum introduced by the fractional-N division. Component and parameter selection allow a high degree of resolution in frequency control of the fractional-N PLL. By directly controlling for the frequency error, a DAC and XTAL oscillator tuning circuit may be eliminated from the AFC circuit.

摘要： The present invention provides a method and apparatus for scheduling message processing. The present invention provides a scheduling mechanism, or scheduler (602), that receives messages (608) and stores the messages (610 or 614) in a first queue (604) or a second queue (606) based, in part, on various criteria associated with the messages. The criteria include message attributes, such as message priority, virtual private network ('VPN') classification and destination software function. The first queue (604) can be a first-in-first-out queue, and the to second queue (606) can be a multi-dimensional queue. The scheduler (602) then schedules the queued messages (612 or 616) for processing based, in part, on various operating criteria (618), such as historical operating data, current operating data and anti-starvation criteria. In addition, the scheduler (602) can be programmed to function in a variety of operating modes.

摘要： Received signal quality (bit error rate) estimates for a communication channel are provided by a receiver apparatus which is connected to the communication channel and which includes a convolutional decoder providing an estimate of a transmitted data frame and an associated final decision metric. The bit error rate estimate is generated by a bit error rate estimation circuit which includes a memory containing values for mapping the final decision metric to a corresponding bit error rate estimate. The bit error rate estimate may be provided to a control node of the communication channel which may use the provided estimate to take a corrective action such as determining whether a handover to a different communication channel should be initiated based upon the bit error rate. The communication channel may be an allocated channel of a cellular radio communication network servicing a mobile terminal receiver apparatus with the control nodes being the base stations of the cellular network. The convolutional decoder may be a Viterbi decoder.

摘要： A method for decoding encoded digital data. A decoder generates a replicated decoding trellis and performs some number Dmax of decoding operations using the replicated trellis. Each decoding pass is offset by some amount δ, and the results of each pass are stored and compared with prior results to generate a final output information sequence.

摘要： An apparatus and method for improving the rescan capability of a telecommunications system searching for an Acceptable Service Provider (ASP) after a failure by a given mobile terminal to link with the ASP. After a mobile terminal's communication link with an ASP has been severed or during startup, i.e., whenever the ASP is temporarily unavailable, a mobile terminal, now camped upon an Unacceptable Service Provider, performs one or more partial rescans to re-establish contact with the ASP before performing a full power-up rescan.

摘要： A mobile communication system comprises a plurality of cells, with each cell including a network of microstations distributed more or less uniformly throughout the cell. A central controller connected to the network of microstations selects a group of microstations in the vicinity of the mobile terminal to transmit information to the mobile terminal. The selected microstations in the active set for a given mobile terminal is continuously updated as the mobile terminal moves through the network of microstations to form a virtual cell that follows the mobile terminal through the network. Transmission conflicts between two mobile terminals is avoided by inhibiting transmissions from an active microstation to at least one of the co-channel mobile terminals when a transmission conflict is detected.
