    Abstract: A method and apparatus for operating a wireless telecommunication system utilizing code division multiple access (CDMA) over-the-air with a Global System for Mobile communications (GSM) A-interface based network is described. A CDMA radio frequency (RF) signal interface provides a bi-directional interface to a subscriber unit, and a Global System for Mobile (GSM) communications A-interface SS7 transport provides a bi-directional interface with GSM mobile services switching center (MSC). Additionally, a transparent message transport is provided over which signaling messages defined in the GSM A-interface protocol are exchanged between the GSM MSC and a subscriber unit. Other signaling message generating by the GSM MSC and subscriber unit are processed and various actions are taken in response, including the configuration and control of signal processing resources. This configuration and control includes the allocation of vocoding and devocoding resources in accordance with the requested type of service, and the invocation of CDMA based encryption capabilities. Other actions include the allocation of CDMA traffic channel processing resources and selection resources at the start of a signaling exchange between the subscriber unit and the BSS or MSC. These resources process both voice and data calls, and signaling messages, such as registrations, from the subscriber unit. The CDMA traffic channel resources are used to perform the IS-95 style CDMA signal processing functions including modulation and demodulation.

    Abstract: EL SISTEMA INALAMBRICO COMPRENDE UNO O MAS TELEFONOS PUBLICOS (12) DESDE LOS QUE LOS USUARIOS PUEDEN INICIAR LLAMADAS DE TELEFONO DE PAGO PREVIO. UN CENTRO DE CONMUTACION MOVIL (16) CONECTA LAS LLAMADAS TELEFONICAS INICIADAS EN LOS TELEFONOS DE PAGO INALAMBRICOS CON UNOS SISTEMAS TELEFONICOS EXTERNOS (18) TAL COMO LA RED TELEFONICA DE CONMUTACION PUBLICA (PSTN). PARA COMPUTAR LAS TASAS INCURRIDAS DURANTE LA LLAMADA TELEFONICA EN UN SISTEMA EXTERNO, EL SISTEMA EXTERNO TRANSMITE UNOS IMPULSOS DE TARIFICACION PERIODICOS (52, 54) AL CENTRO DE CONMUTACION MOVIL. CADA IMPULSO REPRESENTA UNA CANTIDAD PREDETERMINADA DE DINERO ASOCIADA A LA LLAMADA TELEFONICA. LA VELOCIDAD DE TRANSMISION DE LOS IMPULSOS PERIODICOS AL CENTRO DE CONMUTACION MOVIL DEPENDE DE LA TASA DE FACTURACION VIGENTE Y PUEDE VERSE ALTERADA POR LA HORA DEL DIA, POR EJEMPLO. EN LUGAR DE TRANSMITIR TODOS LOS IMPULSOS DE TARIFICACION AL TELEFONO PUBLICO INALAMBRICO, QUE CONSUMIRIA UNA PORCION DEL ANCHO DE BANDA DISPONIBLE PARA LAS LLAMADAS CON EL TELEFONO INALAMBRICO, EL CENTRO DE CONMUTACION MOVIL (16) CALCULA UNA TASA DE FACTURACION FIJA A PARTIR DE LOS IMPULSOS DE TARIFICACION Y A CONTINUACION UNICAMENTE TRANSMITE LA TASA DE FACTURACION FIJA AL TELEFONO PUBLICO INALAMBRICO.

    Abstract: A wireless telephone system includes one or more payphones 12 from which users may make calls. A mobile switching centre 16 connects the calls to an external system such as a PSTN. To meter charges incurred during the telephone call within the external system, the external system transmits metering pulses to the mobile switching centre. Each pulse is representative of a predetermined amount of money associated with the telephone call. The rate at which the periodic pulses are transmitted to the mobile switching centre depends on the current billing rate, and may be affected by, for example, the time of day. Rather than forwarding all of the metering pulses to the wireless payphone, therefore consuming bandwidth, the switching centre calculates a steady state billing rate from the pulses then transmits only the steady state billing rate to the wireless payphone. If the rate changes, then the changed billing rate is transmitted to the phone.
