Abstract

The invention discloses a method for assessing quality of service of an A-GNSS server and a system thereof. The assessment is performed mainly beginning from the service availability, reliability andintegrity of the A-GNSS server, the support capacity of multiple auxiliary positioning technologies and the protocol support capacity. The method for assessing the reliability of auxiliary positioningdata of the A-GNSS server comprises the following steps: sending an auxiliary positioning request of a known positioning auxiliary result to an A-GNSS server through a positioning terminal virtual machine; judging whether a positioning auxiliary result fed back by the A-GNSS server is consistent with concerned data in the known positioning auxiliary result; and judging that the auxiliary positioning data provided by the A-GNSS server is reliable if the positioning auxiliary result fed back by the A-GNSS server is consistent with concerned data in the known positioning auxiliary result; or judging that the auxiliary positioning data provided by the A-GNSS server is unreliable if the positioning auxiliary result fed back by the A-GNSS server is inconsistent with concerned data in the knownpositioning auxiliary result. Through the method disclosed by the invention, the problem that the quality of service of the A-GNSS server cannot be intuitively judged at present is solved.

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...
