    Abstract: A mobile terminal for communicating with a base station in a packet radio services network. The terminal has a processor for determining one of a plurality of channels for communication between the mobile terminal and the base station; for digitally coding speech to provide speech information; for assembling speech information into speech packets; and for generating channel allocation requests for a channel in which to send speech packets. A radio transmitter is provided for transmitting the requests and the packets to a base station in the network. A radio receiver receives identities of channels allocated by the base station for the mobile terminal to transmit on. The processor is responsive to each received channel allocation to determine that packets are sent on the allocated channel.In the GPRS since a channel is released when there is no packet to transmit, higher traffic levels can be obtained using the same number of radio channels.

    Abstract: A method is provided for controlling a wireless communications system. The method comprises communicating data to a first base station, and selecting a switchover time for ceasing communications with the first base station and beginning communications with a second base station. The switchover time is based on channel conditions associated with the communications to the first and second base stations, such as SIR.

    Abstract: In a 3GPP standards Release 6 UMTS system, in order to avoid searching at NodeB for a maximum E-DPCCH-associated metric at discrete possible valid index values, or over disjoint possible valid index regions, at the UE the three different sources of information, the fixed number bits that comprise the RSN, TFI and the H-bit components of the E-DPCCH bit field, are mapped so that the decimal equivalents of the possible E-DPCCH indices lie within a continuous range of values.

    Abstract: Un sistema de comunicación incluye una arquitectura plana, descentralizada en donde una pluralidad de nodos base cada uno incluye capacidades de controlador para que no se requiera un nodo base centralizado tal como un controlador de red de radio. Al menos uno de los nodos base actúa como un nodo de anclaje. El nodo de anclaje asocia un sello de tiempo con al menos un paquete y proporciona éste a la pluralidad de nodos base. En un ejemplo, se utiliza un acercamiento de difusión múltiple por un dispositivo de enrutador para distribuir el paquete y el sello de tiempo asociada con la pluralidad de nodos base. Cada nodo base controla un cronometraje de una transmisión de al menos un paquete en una interfaz inalámbrica en respuesta a el sello de tiempo asociada.
