Abstract

The invention discloses a method and a system for evaluating the service quality of an A-GNSS server, mainly from the aspects of service availability, reliability, integrity of the A-GNSS server, support capability and protocol support capability of various assisted positioning technologies to evaluate. When evaluating the A-GNSS server-assisted positioning data reliability method, the method includes the following steps: sending an assisted positioning request with known positioning assistance results to the A-GNSS server through the positioning terminal virtual machine; judging that the positioning assistance results fed back by the A-GNSS server match Whether the data of interest in the known positioning assistance results are consistent; if they are consistent, it is determined that the assisted positioning data provided by the A-GNSS server is reliable; otherwise, the assisted positioning data provided by the A-GNSS server is determined to be unreliable. The present invention solves the problem that the service quality of the A-GNSS server cannot be judged intuitively at present.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to A-GNSS assisted global positioning system technology. Background technique [0002] Currently, terminals that support SUPL protocol-assisted positioning have no intuitive way to judge whether the selected A-GNSS server is available, reliable, supports the most complete positioning technology and the latest version of the protocol and its extensions. An unavailable / unreliable A-GNSS server will prolong the terminal positioning speed and reduce the terminal positioning reliability. An A-GNSS server that does not fully support the latest protocol version and extensions will invalidate the new functions and extensions supported by the terminal. After the user experience deteriorates, end users will passively change the A-GNSS server. [0003] At present, the A-GNSS server that provides services is used as a background service, and there is no detailed version description, se...
