Abstract: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.

Abstract: In a receiver having a plurality of demodulation elements, a method of assigning the plurality of demodulation element so a set of available signals. A first method emphasizes diversity of transmitting devices so that power control is optimal. A second method emphasizes the maximum signal strength available to produce aggregate maximum signal strength. Both methods control the number of reassignments so that excessive data is not lost during the reassignment process. The apparatus comprises the plurality of demodulation elements, at least one searcher element, and a controller.

Abstract: A method and apparatus for selecting a communication system in accordance with the geographic region in which the subscriber station is located is described. Upon successful acquisition, a system determination processor examines the received system identification information and compares it with system identification information stored in a universal system table to determine the geographical region of the identified communication system. The system determination processor then determines whether the acquired system is the most desirable system for use in the geographical region. If it is the most desirable system for use in the geographical region, the system determination processor selects the acquired system for providing service. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system using information from the universal system table.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information sig- nals between one another via at least one cell-site using code division multiple access spread spectrum communication sig- nals. The power control system controls transmission signal power for each cellular mobile telephone (16, 18) in the cellu- lar mobile telephone system wherein each cellular mobile telephone (16, 18) has an antenna, transmitter and receiver and each cell-site (12, 14) also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to in- creases and decreases in received signal power. A power con- trol feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit trans- mitted power is measured as received at the cell-site. A com- mand signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell-site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power corresponding to devia- tions in the cell-site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level. In a cell diversity situation, the mobile units transmitter power is adjusted to prevent un- necessary increases in mobile unit transmitter power level.

Abstract: UN SISTEMA DE CONTROL DE POTENCIA PARA UN SISTEMA TELEFONICO MOVIL CELULAR EN EL CUAL LOS USUARIOS DEL SISTEMA SE COMUNICAN SEÑALES DE INFORMACION ENTRE UNO Y OTRO A TRAVES DE AL MENOS UN LUGAR CELULAR QUE UTILIZA SEÑALES DE COMUNICACION DE ESPECTOR DE ESPARCIMIENTO DE ACCESO MULTIPLE DE DIVISION DE CODIGO. EL SISTEMA DE CONTROL DE POTENCIA CONTROLA LA POTENCIA DE LA SEÑAL DE TRANSMISION PARA CADA TELEFONO MOVIL CELULAR (16, 18) EN EL SISTEMA MOVIL CELULAR EN EL QUE CADA TELEFONO CELULAR MOVIL (16, 18) TIENE UNA ANTENA, UN TRANSMISOR Y UN RECEPTOR. LA POTENCIA DE SEÑAL TRANSMITIDO DE UN LUGAR CELULAR SE MIDE AL RECIBIRLA EN LA UNIDAD MOVIL. EL PODER DE TRANSMISION SE AJUSTA A LA UNIDAD MOVIL DE UNA MANERA OPUESTA RESPECTO DE LOS INCREMENTO Y DECRECIMIENTOS EN LA POTENCIA DE SEÑAL RECIBIDA. UN ESQUEMA DE RETROALIMENTACION DE CONTROL DE POTENCIA PUEDE TAMBIEN SER UTILIZADO. EN EL LUGAR CELULAR QUE COMUNICA CON LA UNIDAD MOVIL, SE MIDE LA POTENCIA TRANSMITIDA DE LA UNIDAD MOVIL AL SER RECIBIDAEN EL LUGAR CELULAR. UNA SEÑAL DE MANDO SE GENERA EN EL LUGAR CELULAR Y SE TRANSMITE A LA UNIDAD MOVIL PARA AJUSTAR LA POTENCIA DEL TRANSMISOR DE LA UNIDAD MOVIL QUE CORRESPONDE A LAS DESVIACIONES EN LA POTENCIA DE LA SEÑAL DEL LUGAR CELULAR EL ESQUEMA DE RETROALIMENTACION SE UTILIZA PARA AJUSTAR LA POTENCIA DEL TRANSMISOR DE LA UNIDAD MOVIL DE MANERA QUE LAS SEÑALES TRANSMITIDAS DE LA UNIDAD MOVIL LLEGUEN AL LUGAR CELULAR A UN NIVEL DE POTENCIA DESEADO. EN UNA SITUACION DE DIVERSIDAD CELULAR, LA POTENCIA DEL TRANSMISOR DE LA UNIDADES MOVILES SE AJUSTA PARA EVITAR INCREMENTOS INNECESARIOS EN EL NIVEL DE POTENCIA DEL TRANSMISOR DE LA UNIDAD MOVIL.
