    Abstract: Un controlador de red de radio, RNC (Radio Network Controller, en inglés), dispositivo (124) que comprende: una memoria (314) adaptada para almacenar una pluralidad de instrucciones; y una unidad de procesamiento (312) adaptada para ejecutar instrucciones en la memoria, estando la unidad de procesamiento (312) dispuesta por ello para: recibir información relativa a la asignación de un identificador temporal de red de radio de canales dedicados mejorados, E-RNTI (Enhanced Dedicated Channel Radio Network Temporary Identifier, en inglés) (460) a un equipo de usuario (110) en un canal de acceso de transmisión de celdas, estado de Cell_FACH, estando el dispositivo RNC caracterizado porque la unidad de procesamiento está también dispuesta para: recibir información relativa a un cambio de estado (520) del equipo de usuario (110), determinar que el E-RNTI (460) puede ser liberado basándose en el cambio de estado (520), donde el cambio de estado implica que el E-10 RNTI ya no es utilizado por el equipo de usuario (110), y proporcionar, a una estación de base (122), una solicitud (530) para liberar el E-RNTI (460) en respuesta al cambio de estado (520) y de manera que el E-RNTI (460) pueda ser utilizado por otro equipo de usuario (110).

    Abstract: A mobile telecommunications network having an integrated wireless office system is disclosed. A wireless office system is integrated into both a private telephony network (PTN) and a public land mobile network (PLMN) which includes a public cellular system. The wireless office system provides mobile service to corporate mobile terminals (CMTs) that are part of a corporate group of terminals of the PTN. The CMTs of the wireless office system appear to the PTN as normal fixed extension terminals and PTN internal features such as call back, caller identification and operator assistance may be used at the CMTs.

    Abstract: In a radio network, the implementation of IP signaling may be used to provide end-to-end Quality of Service. This may be accomplished by mapping corresponding parameters between the IP protocol and the radio network protocol in order to achieve the desired delay and bandwidth requirements. Various events in the state machines of the protocols may also be used to trigger interworking functions.

    Abstract: The present invention provides flexible radio access and resource allocation in a Universal Mobile Telephone System (UMTS). A UMTS Terrestrial access network (UTRAN) in response to a radio access bearer service request, flexibly and efficiently allocates resources necessary to support a communication with a mobile radio. The UTRAN includes plural base stations for communicating with mobile radios over a radio/air interface using radio channel resources allocated by a radio network controller connected to the base stations. External network service nodes interfacing with external networks communicate with the UTRAN over a radio access network interface. The UTRAN provides a radio access bearer service to the external network service nodes, and radio access bearers are dynamically assigned to radio channel resources by the UTRAN. When establishing each bearer, the UTRAN flexibly maps or allocates the radio access bearer to physical transport resources through the UTRAN and radio channel resources over the radio/air interface. In an example embodiment, the transport between nodes and the UTRAN includes an ATM connection, and a radio channel over the air interface includes one or more CDMA spreading codes. The mapping is based on one or more parameters including for example one or more quality of service parameters and/or current traffic conditions. In addition, if the one or more parameters changes during the life of the connection, the connection may be switched to a more appropriate channel type.
