Abstract:
PROBLEM TO BE SOLVED: To enhance the quality of service and improve the network efficiency in order to provide services at high data rates.SOLUTION: An access terminal is configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal is further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC provides an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for testing the performance of protocols and messages against terminals and access points in CDMA systems.SOLUTION: The performance test comprises a Forward Test Application Protocol (FTAP) for testing forward channels and a reverse test application for testing reverse channels. Techniques are also provided to (1) test different types of channels (e.g., traffic channels as well as auxiliary channels), (2) test bursty data transmissions, (3) support "persistence" testing (i.e., continued testing over connection and disconnection), (4) force the settings of certain auxiliary channels (e.g., so that the error rate of the channels may be determined), and (5) collect, log, and report various statistics that may be used to derive performance metrics such as throughput and packet error rate.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for efficient use of communication resources in a data communication system under an overload condition.SOLUTION: In a communication system (1400) for communication of data, a method and apparatus are configured to detect a request for opening a connection for a user (1407) for communication of data, select an open connection, release the selected open connection, and allocate, to the user (1407), communication resources corresponding to resources released based on releasing the selected open connection. In accordance with an embodiment, the selected open connection is in an idle open state.
Abstract:
"método e equipamento para testar canais de tráfego e canais auxiliares em um sistema de comunicação de dados sem fio". trata-se de técnicas para testar o desempenho de terminais e pontos de acesso em sistemas de dados cdma (como o cdma2000, por exemplo). uma estrutura de protocolos e mensagens é apresentada para suportar a verificação sistemática do desempenho de terminais e para assegurar compatibilidade de interface. a estrutura compreende um protocolo de aplicação de testes de emissão (ftap) para testar canais de emissão e um protocolo de aplicação de testes reversos (rtap) para testar canais reversos. são também apresentadas técnicas para (1) testar tipos diferentes de canal (como, por exemplo, canais de tráfego assim como canais auxiliares, (2) testar transmissões de dados em rajadas, (3) suportar verificação de "persistência" (isto é, verificação contínua através de conexão e desconexão), (4) forçar os ajustes de determinados canais auxiliares (como, por exemplo, de modo que a taxa de erro dos canais possa ser determinada), e (5) reunir, registrar e relatar diversas estatísticas que podem ser utilizadas para obter critérios de desempenho tais como rendimento e taxa de erro de pacote.
