    Abstract: In a wireless communication system, a method and apparatus of communicating between at least one base station and a core network is claimed. Signaling messages and voice streams are transported using packet-switched protocols (IP). A CIC field (Circuit Identity Code) is used to identify at least one VoIP streams. The CIC field may be interpreted as a UDP port number for the voice over IP stream. Also, a synchronization source or contributing source filed of a RTP header may be used as the CIC field (fig. 1).

    Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment of the invention comprises a method of performing position location in a wireless subscriber unit having a local oscillator, including the steps of receiving a position location request, acquiring a timing signal when a sufficient period of time has elapsed since the local oscillator has been corrected and correcting said local oscillator using a correction signal based on said timing signal, substantially freezing the correction signal, performing a position location procedure using the local oscillator with the correction signal applied, and ending said position location procedure.

    Abstract: A novel and improved method for performing paging is described. In one embodiment of the invention a searcher (206) is used to detect spread spectr um signals. Samples received RF signals are stored in a sample buffer. During standby mode, the samples are gathered during paging slots assigned to the mobile. A set of searches are performed on the samples, and if pilot signals are detected additional demodulation is performed to detect paging messages. The resulting set of demodulation data may be combined to increase detection . After a page message has been detected, additional demodulation resources ma y be activated to process more complete page messages, or other information channels. In one embodiment of the invention, the searcher (206) includes a demodulator to perform quick page detection without the use of finger elemen ts to reduce idle mode power consumption.

    Abstract: "geração e implementação de um protocolo e uma interface de comunicação para transferência de sinal com alta taxa de dados". uma interface de dados para transferência de dados digitais entre um host e um cliente através de uma via de comunicação, usando estruturas de pacotes ligadas para formar um protocolo de comunicações para comunicar um conjunto pré-selecionado de dados digitais de controle e apresentação. o protocolo de sinal é usado por controladores de link configurados para gerar, transmitir e receber pacotes formando o protocolo de comunicações e para formar dados digitais em um ou mais tipos de pacotes de dados, com pelo menos um residindo no dispositivo host e estando acoplado ao cliente através da via de comunicação. a interface propicia um mecanismo de transferência de dados de alta velocidade, bidirecional, de baixa potência e eficaz em termos de custo através de um link de dados de curto alcance do tipo "serial", que se presta à implementação com conectores miniatura e cabos flexíveis finos, os quais são especialmente úteis para conexão de elementos de display tais como micro-displays de uso pessoal (wearable) para computadores portáteis e dispositivos de comunicação sem fio.
