Abstract: In a digital communication system for communicating digital information, the digital communication system having a forward link and a reverse link, a system and method for communicating a data packet. The system comprises a communicating transceiver, from among a number of digital transceivers, for sending the data packet on a random access channel over the reverse link and for receiving the digital information from the forward link. The system also comprises a base station for receiving the data packet on the random access channel from the reverse link and for sending the digital information over the forward link. The digital transceivers share the random access channel. The digital transceivers have a bandwidth demand. The system may also include a dedicated channel for communicating the data packet between the communicating transceiver and the base station and a processor for switching from the random access channel to the dedicated channel when the bandwidth demand exceeds a first threshold, and for switching from the dedicated channel to the random access channel when the bandwidth demand drops below a second threshold. The system is well suited for use in CDMA applications.

Abstract: A system and method for reducing the interference experienced by sensitive electronic devices, such as hearing aids, operative in the vicinity of CDMA user communication devices (10). A transmitter (56) of the communications device (10) is configured to transmit signal power substantially continuously at a full rate power level irrespective of the variable data rate at which the transmitter (56) would otherwise be operative. In a first embodiment, a variable rate vocoder (16) within the transmitter is directed to perform fullrate vocoding, irrespective of an instantaneous level of user speech. In a second embodiment, a microprocessor (18) builds full-rate frames using repeated versions of code symbols generated by the vocoder (16). In a third embodiment, the microprocessor (18) builds full rate frames by generating signaling bits of a predetermined pattern to pad otherwise non-full frames.

Abstract: A method and apparatus for providing soft hand-off in a mobile communication system. In current systems, members of an active set of base stations (4, 4A, 4B, 4C) are determined by comparing measured pilot energy with fixed thresholds. The value of providing a redundant communication link to a mobile station (2) primarily depends on the energy of other signals being provided to the mobile station (2). In the present invention, the signal strength of each signal transmitted by other base stations (4, 4A, 4B, 4C) in communication with a mobile station (2) is considered when determining whether to add a base station to the set of base stations (4, 4A, 4B, 4C) in communication with the remote station. A base station is added only if the signal received from that base station provides sufficient added value to justify the impact on system capacity.

Abstract: The mobile telephone system employs a fleet of satellites (214) and a set of gateway ground stations (210) arranged around the globe for handling communications to and from mobile communication units such as mobile telephones. Signals are transmitted between a subscriber (212) unit and the nearest gateway (210) via one or more of the satellites (214). The gateway is connected to a set of individuel service providers (216) such as local telephone systems. The individual service providers may be constrained for various reasons such as contractual or other legal constraints to handle communications only from subscriber units (212) located in certain geographical areas such as within only certain countries or portions of countries. For a mobile communication from a particular subscriber unit (212), the gateway selects (210) a service provider (216) capable of handling the communication. In one implementation, the selection is based upon the location of the subscriber unit and upon any references specified by the subscriber unit. In other implementations, the selection is based on other parameters such as the altitude, speed or velocity of the subscriber unit or the time of day or date upon which the communication is initiated.

Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronizing crypto-syncs at the mobile station and base station is also presented.

Abstract: A method and apparatus for providing soft handoff in a mobile communication system. In current systems is that the members of active set are determined in accordance with comparisons of measured pilot energy with fixed thresholds. However, the value of providing a redundant communication link to a mobile station depends strongly on the energy of other signals being provided to the mobile station. In the present invention, the signal strengths of other base stations in communication with a mobile station are considered when determining whether adding a base to that set of base stations in communication with the remote station is of sufficient value to justify the impact on system capacity.

Abstract: SE EXPONE UN PROCEDIMIENTO Y APARATO PARA PROPORCIONAR UNA TRANSFERENCIA POR SOFTWARE EN UN SISTEMA DE COMUNICACIONES MOVILES. EN LOS SISTEMAS ACTUALES, LOS MIEMBROS DE UN CONJUNTO ACTIVO DE ESTACIONES BASE (4, 4A,4B,4C) ESTAN DETERMINADOS MEDIANTE LA COMPARACION DE LA ENERGIA PILOTO MEDIDA CON LOS UMBRALES FIJADOS. EL VALOR DE PROPORCIONAR UN ENLACE DE COMUNICACION REDUNDANTE A UNA ESTACION MOVIL (2) DEPENDE PRINCIPALMENTE DE LA ENERGIA DE LAS OTRAS SEÑALES QUE SE PROPORCIONAN A LA ESTACION MOVIL (2). EN LA PRESENTE INVENCION, LA INTENSIDAD DE LA SEÑAL DE CADA SEÑAL TRANSMITIDA POR LAS DEMAS ESTACIONES BASE (4, 4A,4B, 4C) EN COMUNICACION CON UNA ESTACION MOVIL (2), SE CONSIDERA AL DETERMINAR SI AÑADIR O NO UNA ESTACION BASE AL CONJUNTO DE LAS ESTACIONES BASE (4,4A,4B,4C) EN COMUNICACION CON LA ESTACION REMOTA. SE AÑADE UNA ESTACION BASE SOLO SI LA SEÑAL RECIBIDA DE DICHA ESTACION BASE PROPORCIONA UN VALOR AÑADIDO SUFICIENTE PARA JUSTIFICAR EL IMPACTO EN LA CAPACIDAD DEL SISTEMA.
