摘要： Un sistema de radio celular que comprende estaciones de base de radio (A, B, C) cada una tiene un numero asignado de canales de radio. Cada estacion de base de radio se conecta al resto de la red (BSC, MSC) por una red ramificada (5, 7a, 7b, etc.). En el punto H de la ramificacion se proporciona un conmutador intermediario para conectar canales en la porcion (5) troncal a canales en las ramas (7a, 7b, etc). La capacidad del enlace (5) troncal es menor que la capacidad total de las estaciones de base (y sus enlaces de ramificacion asociados) (7a, 7b, 7c). En los momentos cuando una o más estaciones de base (A, B, C) tienen capacidad excelente se inactiva la capacidad de manera que no se exceda la capacidad del enlace (5) troncal. Se puede hacer variar la capacidad de cada estacion de base (A, B, C) de acuerdo con una demanda predicha o real, con la condicion de que la capacidad total (no inactivada) de las estaciones de base (A, B, C) no excede a la de la línea (5) troncal.

摘要： Las unidades de radio movil (11, 21) que comunican con sus estaciones de base respectivas a una velocidad de bitio bajo que la velocidad de conmutacion convencional de una red fija. Cuando la comunicacion se hace entre un usuario movil (11) y un suscriptor convencional para el sistema de 64 kbit/s PSTN o entre un suscriptor convencional y un receptor (21). Tales llamadas son identificadas por los dispositivos reconocedores de movil a movil (17 y 27) que identifican las corrientes de bitio características y manejan las llamadas de manera apropiada. El primer dispositivo reconocedor de movil a movil (17) está ubicado en el lado fijo de la interfase de aire (14) y, para una llamada normal dirige la llamada hacia el transcodificador de ley-A (15). El dispositivo reconocedor de movil a movil (27) identifica las llamadas que llegan desde el conmutador 64 kbit/s (10), y para la llamada normal dirige la llamada hacia el transcodificador de alta velocidad digital a ley-A (26) como se describio antes con referencia a la Figura 2. Si una llamada es establecida entre dos usuarios moviles (11, 21) el dispositivo reconocedor de movil a movil (17) identifica tal llamada, por ejemplo, mediante conocimiento de numero en la fase de establecimiento de llamada y desvía la llamada recibida sobre la interfase de aire (14) hacia un justificador de bitio (18). El justificador de bitio (18) crea cuadros de kilobitio (64) desde los cuadros de kilobtiio (16) proporcionando tres bitios nulos para cada bitio recibido sobre la interfase de aire. Los bitios nulos pueden ser numeros aleatorios, aunque preferiblemente incluyen un patron reconocible que puede ser detectado por un segundo dispositivo reconocedor de movil a movil (27). Mediante la "justificacion de bitio" de esta manera una señal 64 kbit/s puede ser generada desde una señal 16 kbit/s con mínimo procesamiento de señal y sin la necesidad de transcodificar a la ley-A y de regreso. El dispositivo reconocedor de movil a movil (27), puede ser controlado, ya sea mediante reconocimiento de la identidad del numero llamado o mediante reconocimiento del patron característico de bitios nulos en una señal justificada por bitio generada por el justificador de bitio (18) y direcciona la señal hacia el separador de bitio (28) en lugar de hacia el transcodificador de alta velocidad digital a ley-A (26). El separador de bitio remueve los bitios nulos y transmite solamente las señales que conforman la señal original 16 kbit/s. Estas son transmitidas sobre la interfase de aire (24) al decodificador de baja velocidad de bitio (23) a ley-A y por tanto hacia el convertidor A a D (22) y el alta voz (21).

Date Feb. 6, 1997Mobile radio units communicate at a lower bit-rate than the conventional switching rate of a fixed network. Such calls are identified by mobile-to-mobile recognizers which identify characteristic bit streams and handle calls appropriately. An incoming mobile-to-mobile recognizer normally routes the call to a digital to A-law transcoder. An outgoing mobile-to-mobile recognizer normally routes calls to a high bit-rate digital to A-law transcoder. If a call is established between two mobile users the first-mobile-to-mobile recognizer diverts the signal received to a bit stuffer which provides three null bits for every bit received over the air interface. The null bits may be random numbers, but preferably include a recognizable pattern which can be detected by the second mobile-to-mobile recognizer. By such "bit sutffing" a 64 kbit/s signal can be generated from a 16 kbit/s signal with minimal signal processing and without the need to transcode to A-law and back.

Date Feb. 6, 1997A mobile telephone system has a base transceiver station (BTS) that provides radio communication with a mobile handset (MS) and also communicates with a control station (BSC) through a communication link in the form of a leased line which provides a first communication path with a predetermined bandwidth for signals communicated between the BTS and the BSC. A communication network in the form of an ISDN is used to provide a selectively connectable second communication path between the BTS and the BSC so as to augment the bandwidth available for the signals during periods of peak demand. In order to accommodate different call connection times in the system through the leased line and the ISDN, the BSC/BTS are arranged to produce all connection signals that initiate billing at the same time irrespective of the path used to make the call connection.

摘要： Mobile radio units (11, 21) communicate with their respective base stations at a lower bit-rate than the conventional switching rate of a fixed network. Wh en communication is made between a mobile user (11) and a conventional subscrib er to the 64 kbit/s PSTN system, or between such a conventional subscriber and a receiver (21). Such calls are identified by mobile to mobile recognisers (17 and 27) which identify characteristic bit streams and handle calls appropriately. The first mobile to mobile recogniser (17) is located at the fixed side of the air interface (14) and, for a normal call routes the call to the digital to A-law transcoder (15). The mobile to mobile recogniser (27) identifiers calls coming from the 64 kbit/s switch (10), and for a normal ca ll routes the call to the high bit-rate digital to A-law transcoder (26) as described above with reference to Figure 2. If a call is established between two mobile users (11, 21) the mobile to mobile recogniser (17) identifies su ch a call, for example by number recognition in the call set up phase and diver ts the signal received over the air interface (14) to a bit stuffer (18). The b it stuffer (18) creates (64) kilobit frames from (16) kilobit frames by providi ng three null bits for every bit received over the air interface. The null bits may be random numbers, but preferably include a recognisable pattern which c an be detected by a second mobile to mobile recogniser (27). By "bit stuffing" in this way a 64 kbit/s signal can be generated from a 16 kbit/s signal with minimal signal processing and without the need to transcode to A-law and bac k. The mobile to mobile recogniser (27), may be controlled, either by recogniti on of the identity of the calling number, or by recognition of the characterist ic pattern of null bits in a bit-stuffed signal generated by bit stuffer (18), and routes the signal to bit stripper (28) instead of to the high bit digita l- to-A-law transcoder (26). The bit stripper removes the null bits and transmi ts only the signals making up the original 16 kbit/s signal. These are then transmitted over the air interface (24) to the low-bit-rate to A-law decoder (23), and thus to the A to D converter (22) and the listener (21).
