    • Systems and methods are provided for location determination in wireless communication networks. A client device with a location provider installed is configured to provide location data to a data engine server and to obtain location service from a positioning engine server or the location provider itself. The location provider based on one or more components implements the reference data delivery function and the client location determination function. The data engine server is configured to process the location data received from one or more client devices and maintain a location database. The data engine server based on one or more components implements the reference data retrieval function, station position calculation function, reference data management function, and assistance data delivery function, as it interacts with the client device. The positioning engine server is configured to process the location request data received from one or more client devices and calculate the locations of the client devices. The positioning engine server based on one or more components implements the positioning data retrieval function and device position calculation function, as it interacts with the client device. The location database stores the previously obtained location data.

    • Systems and methods for event reporting are provided. In a method for event reporting in a system that includes an event source and a plurality of event consumers, notifications from the event source are received at an event reporter. The notifications are received at a first rate. The event reporter receives a plurality of desired sampling rates from the plurality of event consumers, where each of the desired the sampling rates indicates a rate at which an event consumer desires reporting of notifications from the event reporter. The notifications are filtered based on the first rate and the plurality of desired sampling rates. The filtering selects one or more of the notifications to be reported to one or more event consumers of the plurality of event consumers. The selected one or more of the notifications are reported.
    • 提供了事件报告的系统和方法。 在包括事件源和多个事件消费者的系统中的事件报告的方法中,来自事件源的通知在事件记录器处被接收。 以第一个速率接收通知。 事件记者从多个事件消费者接收多个期望的采样率,其中期望的采样率中的每一个指示事件消费者期望从事件记录者报告通知的速率。 基于第一速率和多个期望的采样速率对通知进行滤波。 过滤选择要向多个事件消费者的一个或多个事件消费者报告的一个或多个通知。 所选的一个或多个通知被报告。
