    • Provided herein are methods and systems for efficient communication between a server and a client in an assisted navigation system. In one or more embodiments, the server transmits a set of parameters for a satellite to the client, e.g., a GPS receiver, via a wireless or wired connection. The set of parameters includes a force parameter, initial condition parameters and time correction coefficients for the satellite. The receiver uses the received parameters in a numerical integration to compute the position of the satellite at a desired time. The set of parameters needed for the integration is small. To further reduce the amount of data transmitted, reference parameters may be subtracted from the original parameters before transmission from the server. The receiver is able to reconstruct the original parameters from the received parameters and the identically computed reference parameters. The parameters may be further compressed using data compression techniques.
    • 这里提供了用于在辅助导航系统中的服务器和客户端之间的有效通信的方法和系统。 在一个或多个实施例中,服务器经由无线或有线连接向卫星发送一组用于卫星的参数,例如GPS接收机。 该组参数包括一个力参数,初始条件参数和卫星的时间校正系数。 接收机使用数字积分中接收到的参数来计算卫星在所需时间的位置。 集成所需的一组参数很小。 为了进一步减少发送的数据量,可以在从服务器发送之前从原始参数中减去参考参数。 接收机能够从接收的参数和相同计算的参考参数重建原始参数。 可以使用数据压缩技术来进一步压缩参数。

    • A circuit switched (CS) paging message is received at a multi-mode communication device. The CS paging message is received when a packet switched (PS) service is active at the multi-mode communication device. A PS precedence feature is activated at the multi-mode communication device that prioritizes PS communications over CS communications. A CS bearer connection is established with a CS network in response to receiving the CS paging message, and an incoming call notification message that identifies a calling party is received from the CS network. Upon receipt of the incoming call notification message, the CS bearer connection with the CS network is released. A notification of a missed incoming call from the calling party is displayed (e.g., substantially in real-time) via a user interface.

    • The disclosure discloses a method and a system for measuring a web advertising effect based on a multiple-contact attribution model. The method comprises: collecting user access information and purchase transformation information of a website, and uploading the user access information and purchase transformation information to a server side; cleaning data for the user access information and the purchase transformation information on a server side; calculating contact contribution value data and importing the contribution value serving as fundamental metrics and contact information serving as dimensionalities into OLAP database, and aggregating data. The method and the system can help an advertiser to understand actual web advertising effect from a number of perspectives to accurately measure underestimated or overestimated channel value in conventional methods, thereby providing the most accurate data support for optimizing web advertising and improving rate of return on investment.
