Abstract:
PROBLEM TO BE SOLVED: To save power by utilizing a non-CDMA communication path and to send emergency communication onto a CDMA communication path. SOLUTION: A portable communication device 100 also includes a controller 112 coupled to first transceiver circuitry 104 and second transceiver circuitry 116 for providing a deregistration message to the second transceiver circuitry 116 for transmission therefrom in response to determining that the portable communication device 100 is within signal coverage of the first communication path, activating the first transceiver circuitry 104 to send and receive signals on the first communication path, deactivating the second transceiver circuitry 116, and thereafter activating the second transceiver circuitry 116 at times separated by a predetermined time interval to monitor one or more housekeeping channels of the second communication path.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for determining the time of conducting handoff, from a wireless LAN to another network. SOLUTION: In a wireless communication device which communicates in a wireless local area network, error information in a communication link between the radio communication device, and another device of the wireless local area network is determined in the second layer architecture of the radio communication device (214). Successively, it is determined based on the error information in the communication link, whether handoff from the wireless local area network is to be performed (230). COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
This coordinated floor and packet scheduling for Push-to-X over Cellular (PoC) services delays a packet data slot assignment until after a PoC floor has been granted ( 272 ) by a PoC server ( 251 ). By reducing the time period between slot assignment and floor grant, this method reduces the wasting of packet data network resources while the communication device ( 211 ) is waiting for a PoC floor grant. Setting up a Push-to-X over Cellular (PoC) call session includes an originating communication device ( 211 ) transmitting a PoC floor request message ( 270 ) to a PoC server ( 251 ), the PoC server ( 251 ) sending a PoC floor grant message ( 272 ) with treatment type "floor grant" to a packet control function, ( 232 ), the packet control function ( 232 ) assigning packet data slots to the originating communication device and setting up an active packet data session ( 280 ), and communicating a PoC floor grant and packet data slot assignment message ( 285 ) to the originating communication device ( 211 ).
Abstract:
Este establecimiento de sesion de datos de paquete concurrente para servicios de Pulsar para hablar sobre Celular (PoC) disminuye el tiempo de establecimiento de conexion para una llamada de PoC al utilizar procesos que se basan en conmutacion de circuitos para localizar y buscar un dispositivo de comunicacion llamado, y para iniciar establecimientos de sesion de datos de trafico y de paquete para el dispositivo de comunicacion llamado. Un metodo para establecer una sesion de datos de paquete entre un dispositivo (211) de comunicacion de origen y un dispositivo (215) de comunicacion llamado incluye las etapas de: solicitar un establecimiento de sesion activa de datos de paquete del dispositivo llamado para el dispositivo de comunicacion llamado (mensaje 271, 272, 273, 274, 275), e iniciar un establecimiento de sesion activa de datos de paquete del dispositivo de origen para el dispositivo de comunicacion de origen (mensaje 271, 222, 224). La primera etapa puede utilizar mensajes basados en conmutacion de circuitos y procesos para localizar el dispositivo de comunicacion llamado y establecer un canal de trafico para el dispositivo de comunicacion llamado. Despues de que se establece una sesion (263) activa de datos de paquete para el dispositivo (211) de comunicacion de origen, la sesion (263) activa de datos de paquete del dispositivo de origen pueden utilizarse para solicitar un canal de voz de PoC (mensaje 290). Debido a que ya se ha solicitado un establecimiento de sesion activa de datos de paquete del dispositivo llamado, el dispositivo (215) de comunicacion llamado puede responder a la solicitud de canal de voz de PoC rapidamente (mensaje 293).
Abstract:
La presente invención provee un método para asignar a través de una pluralidad de estaciones base fuente de una infraestructura de soporte de comunicación inalámbrica celular un identificador de solicitud de recursos temporal a un dispositivo de comunicación inalámbrica para tener acceso a una estación base objetivo; el método incluye identificar una lista de identificadores de solicitud de recursos temporales asociados con la estación base objetivo para uso por uno o más dispositivos de comunicación inalámbrica, en donde la lista incluye un subconjunto de uno o más identificadores de solicitud de recursos temporales de tiempo parcial cuya asignación respectiva a un agrupamiento correspondiente de una o más estaciones base fuente, en un tiempo particular, es rotada entre más de uno de la pluralidad de agrupamientos correspondientes de una o más estaciones base fuente; la presente invención además permite la asignación de un identificador de solicitud de recursos temporal a un dispositivo de comunicación inalámbrica para tener acceso a una estación base objetivo, donde un identificador correspondiente de los identificadores de solicitud de recursos temporales es asignado a un dispositivo de comunicación inalámbrica particular, donde el identificador de solicitud de recursos temporal incluye una limitación de uso correspondiente a intervalos de tiempo de comunicación particulares durante los cuales el identificador de solicitud de recursos temporal puede ser utilizado con la estación base objetivo.
Abstract:
The present invention provides for a method for allocating by a plurality of source base stations of a cellular wireless communication support infrastructure a temporary resource request identifier to a wireless communication device for accessing a target base station. The method includes identifying a list of temporary resource request identifiers associated with the target base station for use by one or more wireless communication devices, wherein the list includes a subset of one or more part time temporary resource request identifiers whose respective assignment to a corresponding grouping of one or more source base stations at a particular time is rotated between more than one of the plurality of corresponding groupings of one or more source base stations. The present invention further provides for allocating a temporary resource request identifier to a wireless communication device for accessing a target base station, where a corresponding one of the temporary resource request identifiers is allocated to a particular wireless communication devices, where the temporary resource request identifier includes a limitation of usage corresponding to particular communication time intervals during which the temporary resource request identifier can be used with the target base station.
Abstract:
A first access network [500] has a servicing element [525] for servicing a mobile station 105]. A negotiation element [530] negotiates with a second access network [115] for a right for the second access network [115] to provide wireless service to the mobile station [105]. The negotiation comprises sending an offer of a benefit from the second access network [115] to the first access network [500]. A processor [505] accepts the offer of the benefit from the second access network [115] and transmits a first token [515] to the second access network [115].
