Abstract: A system and method are provided for using Local Number Portability (LNP) and the public switched telephone network (PSTN) trunks as virtual loop-around trunks. Present invention LNP structures and processes redirect calls to avoid the creation of loop-around trunks from calls generated in the local exchange carrier (LEC) requiring services such as prepaid caller and calling party pays. A virtual trunk switch is created using a Switch Control Point (SCP). Telephone numbers requiring special services are ported and stored in a LNP database. Numbers requiring special services are flagged with a LRN that identifies a special service switch which is either an SSP or an SCP. The LRN initiates communication between the local exchange switch and the special service switch. Once engaged, the special service switch protocols create the trunk links. By monitoring these trunk links, the special service switch is able to monitor the in-band communications, and so provide the special services.

Abstract: A personal base station (PBS) having wireless video capability. The PBS authenticates a mobile device within range for cellular services, and authenticates the user for a level of service for cable television. The PBS operates in accordance with a dual-purpose subscriber identity system (SIS) includes a subscriber mobile identity component (SMIC) and a video security component (VSC) such that the cellular and television services can be authenticated. Mobile devices incorporating the disclosed innovations, as well as the PBS, can access video content from a cable television provider through any available broadband link, regardless of the mobile device's physical location.

Abstract: A subscriber identity module (SIM) that facilitates subscriber identity information and subscriber video information. The SIM operates in accordance with a dual-purpose subscriber identity system (SIS) that includes a subscriber mobile identity component (SMIC) and a video security component (VSC) such that the cellular and video services can be authenticated.

Abstract: Embodiments include a system and method for adapting a wireless device, such as a Bluetooth-enabled mobile handset or other Bluetooth-enabled device to a car radio and associated speaker system to effect a hands-free car kit or similar system. The adapter module is physically and electrically coupled to the car radio by making electrical contact with a connector on the car radio with a matching connector on one side of the adapter module. The mated connectors provide communications from the adapter module to the car radio. The adapter module includes circuitry for communicating with the Bluetooth-enabled mobile handset and the car radio in order to exchange communications signals between the Bluetooth-enabled mobile handset, and a microphone and the car radio.

Abstract: Disclosed embodiments include a system and method for adapting a wireless device, such as a Bluetooth-enabled mobile device or other Bluetooth-enabled device to a hands-free car kit or similar system. The adapter module is physically configured so that it can be inserted directly into the cradle in place of the phone. Once inserted into the cradle, the adapter module makes electrical contact with the connector in the cradle with a matching connector on one side of the adapter module. The mated connectors provide power to the adapter module and bi-directional communications between the adapter module and the hands-free car kit. The adapter module includes circuitry for communicating with the Bluetooth-enabled mobile device and the hands-free car kit in order to exchange communications signals between the Bluetooth-enabled mobile device and the hands-free car kit.

Abstract: A universal method of trellis encoding signals mapped according to any signal constellation format involves constructing an encoder output table and a state transition table. The encoder output table defines the output symbol of an encoder given the input symbol and the present state of the encoder, while the state transition table defines the next state of the encoder given the present state of the encoder and the input applied to the encoder. The output table and the next state table are constructed with the objective of providing maximal distances between the branches of the trellis diagram without any regards for the shift register implementation of the code. Cyclic trellis-coded modulation is an example of such codes without feed-forward or feed-back shift register implementations, and with equal or better performance than “optimal” shift register trellis codes with 16 states or less.

Abstract: Good transmission characteristics are achieved in the presence of fading with a transmitter that employs a trellis coder followed by a block coder. Correspondingly, the receiver comprises a Viterbi decoder followed by a block decoder. Advantageously, the block coder and decoder employ time-space diversity coding which, illustratively, employs two transmitter antennas and one receiver antenna.

Abstract: The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session.
