    Abstract: In a dispatch system, power of the forward link broadcast channel transmitted from a base station is controlled such that the power level is the minimum necessary and such that transmission of the forward link broadcast channel is terminated if no remote unit (10) is Located within the coverage area of the base station (32). In addition to transmitting a forward link broadcast signal, the base station monitors an access channel. A first remote unit (10) in the base station coverage area receives and decodes the forward link broadcast signal. The first remote unit (10) determines a signal quality of said forward link broadcast signal. If the signal quality is unacceptable, the remote unit transmits a power request access message. The base station responds to the request by increasing the transmission power of forward link broadcast channel (70). If no requests are received at the base station, the forward link broadcast channel is slowly decreased to a minimum (54). Transmission of the forward link broadcast channel may be terminated completely (58).

    Abstract: A system and method for controlling software applications on one or more wireless devices where each wireless device is in selective communication with one or more application managing servers over a wireless network. Each wireless device has one or more selectively executable resident software applications and at least one software application requires a valid license for each execution, and upon the attempted execution of a software application, the wireless device determines if a license is present. If a license is not present, the wireless device selectively prompts, either automatically or at the direction of the user of the wireless device, an application managing server for transmission of a license, receives the transmitted license, and installs the license on the wireless device such that the software application is again licensed and executable.

    Abstract: PARA REDUCIR EL CONSUMO DE ENERGIA DE UNA UNIDAD REMOTA EN UN SISTEMA DE EXPEDICION LA UNIDAD REMOTA PENETRA EN UN ESTADO DURMIENTE. UNA ESTACION BASE (32) Y TRANSMITE UNA SEÑAL DE EMISION DE ENLACE DE TRANSMISION Y MONITORIZA UN CANAL DE ACCESO COMUN. UNA PRIMERA UNIDAD REMOTA (10) RECIBE Y DECODIFICA DE FORMA CONTINUA LA SEÑAL DE EMISION DE ENLACE DE TRANSMISION Y DETERMINA CUANDO LA SEÑAL DE EMISION DE ENLACE DE TRANSMISION COMPRENDE SEÑALES ACTIVAS (106). SI LA UNIDAD REMOTA DETERMINA QUE LA SEÑAL DE EMISION DE ENLACE DE TRANSMISION NO COMPRENDE SEÑALES ACTIVAS DURANTE ALGUN TIEMPO T 1 , LA PRIMERA UNIDAD REMOTA ENTRA EN UN MODO DURMIENTE (148). EN EL MODO DURMIENTE LA UNIDAD REMOTA RECIBE Y DECODIFICA ESPORADICAMENTE LA SEÑAL DE EMISION DE ENLACE DE TRANSMISION. SI ESTA UNIDAD REMOTA O CUALQUIER OTRA UNIDAD REMOTA EN LA MISMA RED PRESIONA UN BOTON DE INICIO DE CONVERSACION (128, 130), TRANSMITE UN MENSAJE EN EL CANAL DE ACCESO COMUN. EN RESPUESTA, CADA UNIDAD REMOTA EN LA RED QUE ESTAEN UN ESTADO DURMIENTE SALE DEL ESTADO DURMIENTE Y MONITORIZA CONTINUAMENTE LA SEÑAL DE EMISION DE ENLACE DE TRANSMISION.

    Abstract: To reduce the power consumption of a remote unit in a dispatch system the remote unit enters a dormant state. A base station transmits a forward link broadcast signal and monitors a common access channel. A first remote unit continually receives and decodes the forward link broadcast signal and determines whether said forward link broadcast signal comprises active signals. If the remote unit determines that the forward link broadcast signal comprises no active signals for some a duration T1, the first remote unit enters a dormant mode. In the dormant mode the remote unit sporadically receives and decodes said forward link broadcast signal. If this remote unit or any other remote unit on the same net presses a push to talk button, it transmits a message on the common access channel. In response, every remote unit on the net which is in a dormant state exits the dormant state and continually monitors the forward link broadcast signal.

    Abstract: Un sistema y método para actualizar de manera selectiva las versiones de conjuntos de datos almacenados en un dispositivo inalámbrico que de manera selectiva se comunica con un dispositivo inalámbrico y descarga conjuntos de datos, tales como aplicaciones de software e información, desde servidores de descarga situados en la red inalámbrica. El dispositivo inalámbrico tiene un archivo resumen de las versiones de los conjuntos de datos residentes que identifica la versión de cada uno de los conjuntos de datos residentes, y al intentar el dispositivo inalámbrico comunicarse con el servidor de descarga, el dispositivo inalámbrico compara la versión de cada uno de los conjuntos de datos residentes específicos listados en el archivo resumen de las versiones de los conjuntos de datos residentes, con la versión de los conjuntos de datos descargables residentes en el servidor de descarga, a efectos de así determinar si la versión del conjunto de datos residente en el dispositivo inalámbrico es diferente de la versión de un conjunto de datos residente en el servidor de descarga. Si el conjunto de datos residente en el servidor de descarga es mas reciente, el dispositivo inalámbrico puede descargarlo de manera de sobre-escribirlo sobre el conjunto de datos residente en el dispositivo inalámbrico.

    Abstract: A system and method for selectively updating the versions of stored datasets on a wireless device that selectively communicates to a wireless network and downloads datasets, such as software applications and information, from download servers on the wireless network. The wireless device has a resident dataset version summary file that identifies the version of each resident dataset, and upon the wireless device attempting to communicate with the download server, the wireless device compares the version of each specific resident dataset listed in the resident dataset version summary file with the version of downloadable datasets resident on the download server to thereby determine if the version of a wireless device resident dataset is different from the version of a download server resident dataset. If the download server resident dataset is more recent, the wireless device can download it to overwrite the wireless device resident dataset.

    Abstract: A system and method for independently downloading a main program and optional features into a set of storage locations of a wireless communication device uses a memory to store the main program and a set of selected optional features. An identification element associated with one in the set of selected optional features enables the main program to interact with the one in the set of selected optional features. A programmer programs the selected optional feature programs into the memory by locating a storage location in the memory. An indicator indicates when the set of selected optional features has been stored in the memory. The memory can further contain a linking element and a pointer to identify storage locations in the memory. The invention allows the set of selected optional features to be stored after the main program is stored in the memory.
