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 is located within the coverage area of the base station. In addition to transmitting a forward link broadcast signal, the base station monitors an access channel. A first remote unit in the base station coverage area receives and decodes the forward link broadcast signal. The first remote unit 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. If no requests are received at the base station, the forward link broadcast channel is slowly decreased to a minimum. Transmission of the forward link broadcast channel may be terminated completely.

Abstract: A method and apparatus to provide access to a dispatch system is disclosed. A communications manager (40) grants an exclusive system talker privilege to one remote unit (10) in the system at a time. After a remote unit (10) requests and is designated as the exclusive system talker, no other remote unit (20, 22) may transmit for a first pre-determined amount of time. After the first pre-determined time has elapsed, any other remote unit (20, 22) may request the exclusive system talker privilege and become the exclusive system talker. The exclusive system talker privilege is revoked by the communications manager (40) to any remote unit who retains the exclusive system talker privilege for more than a second pre-determined amount of time. The exclusive system talker privilege is also revoked upon the release of a push-to-talk button on a remote unit (10). Furthermore, a base station (44) in communication with a remote unit (10) designated as the exclusive system talker will generate a surrogate relinquishment request to the communications manager (40) if the exclusive system talker travels outside the coverage area of the system, loses power, or is destroyed.

Abstract: A system (10) and method for managing the deleting and reloading of software application components on a wireless device, such as a cellular telephone (12), personal digital assistant (18), pager (20), or other computer platform (22). The wireless device has one or more resident executable software applications wherein each application has one or more application components and application-associated data, such as software licenses and user-specific data. The wireless device selectively deletes one or more application components (86, 88) of the resident software applications without loss of the application-associated data to clear resources on the wireless device (92), and selectively prompts an application download server across a wireless network to transmit deleted application components needed to be re-installed on the wireless device (94) to execute the application.

Abstract: SE EXPONE UN PROCEDIMIENTO Y APARATO PARA PROPORCIONAR ACCESO A UN SISTEMA DE GESTION DE APARATOS MOVILES. UN GESTOR DE COMUNICACIONES (40) CONCEDE A UNA UNIDAD REMOTA (10) DEL SISTEMA EL PRIVILEGIO DE SER LA UNICA QUE EN UN MOMENTO DADO PUEDE HABLAR EN TODO EL SISTEMA. DESPUES DE QUE UNA UNIDAD REMOTA (10) PRESENTE SU SOLICITUD Y SEA DESIGNADA COMO LA UNICA QUE HABLA DEL SISTEMA, NINGUNA OTRA UNIDAD REMOTA (20, 22) PODRA TRANSMITIR DURANTE UN PRIMER PERIODO PREESTABLECIDO DE TIEMPO. UNA VEZ TRANSCURRIDO ESTE PRIMER PERIODO PREESTABLECIDO, CUALQUIER OTRA UNIDAD REMOTA (20, 22) PODRA SOLICITAR EL PRIVILEGIO DE SER EL UNICO QUE HABLA EN EL SISTEMA, Y CONVERTIRSE EN EL MISMO. EL PRIVILEGIO DE SER EL UNICO QUE HABLA DEL SISTEMA LO REVOCA EL GESTOR DE COMUNICACIONES (40) A CUALQUIER UNIDAD REMOTA QUE RETENGA ESTE PRIVILEGIO DURANTE UN TIEMPO SUPERIOR A UN SEGUNDO PERIODO DE TIEMPO PREESTABLECIDO. EL PRIVILEGIO EXCLUSIVO DE SER EL UNICO QUE HABLA DEL SISTEMA SE REVOCA IGUALMENTE CUANDO SE SUELTAEL BOTON DE PULSAR PARA HABLAR DE UNA UNIDAD REMOTA (10). ADEMAS, UNA ESTACION BASE (44), EN COMUNICACION CON UNA UNIDAD REMOTA (10), DESIGNADA COMO LA UNICA QUE PUEDE HABLAR DEL SISTEMA, GENERARA UNA PETICION DE ABANDONO DE SUSTITUCION AL GESTOR DE COMUNICACIONES (40) SI LA UNICA UNIDAD QUE HABLA DEL SISTEMA SE MUEVE SITUANDOSE FUERA DEL AREA DE COBERTURA DEL SISTEMA, SI PIERDE LA POTENCIA O QUEDA DESTRUIDA.

Abstract: EN UN SISTEMA DE EXPEDICION, LA POTENCIA DEL CANAL DE EMISION DE ENLACE DE IDA TRANSMITIDO DESDE UNA ESTACION BASE SE CONTROLA DE FORMA QUE EL NIVEL DE POTENCIA SEA EL MINIMO NECESARIO Y DE FORMA QUE LA TRANSMISION DEL CANAL DE EMISION DE ENLACE DE IDA SE TERMINE SI LA UNIDAD REMOTA (10) NO ESTA SITUADA DENTRO DEL AREA DE COBERTURA DE LA ESTACION BASE (32). ADEMAS DE TRANSMITIR UNA SEÑAL DE EMISION DE ENLACE DE IDA, LA ESTACION BASE CONTROLA UN CANAL DE ACCESO. UNA PRIMERA UNIDAD REMOTA (10) EN EL AREA DE COBERTURA DE LA ESTACION BASE RECIBE Y DECODIFICA LA SEÑAL DE EMISION DE ENLACE DE IDA. LA PRIMERA UNIDAD REMOTA (10) DETERMINA LA CALIDAD DE LA SEÑAL DE LA SEÑAL DE EMISION DE ENLACE DE IDA. SI LA CALIDAD DE LA SEÑAL ES INACEPTABLE, LA UNIDAD REMOTA TRANSMITE UN MENSAJE DE ACCESO DE PETICION DE POTENCIA. LA ESTACION BASE RESPONDE A LA PETICION INCREMENTANDO LA POTENCIA DE TRANSMISION DEL CANAL DE EMISION DE ENLACE DE IDA (70). SI NO SE RECIBEN PETICIONES EN LA ESTACION BASE, EL CANAL DE EMISION DE ENLACE DE IDA SE DISMINUYE LENTAMENTE HASTA UN MINIMO (54). LA TRANSMISION DEL CANAL DE EMISION DE ENLACE DE IDA PUEDE TERMINARSE COMPLETAMENTE (58).

Abstract: To reduce the power consumption of a remote unit in a dispatch system the remote unit enters a dormant state. A base station (32) transmits a forward link broadcast signal and monitors a common access channel. A first remote unit (10) continually receives and decodes the forward link broadcast signal and determines whether said forward link broadcast signal comprises active signals (106). 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 (148). In the dormant mode the remote unit sporadically receive s 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 (128, 130), it transmits a message on the common access channel. In response, every remote unit on the net which is in a dormant sta te exits the dormant state and continually monitors the forward link broadcast signal.
