Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The core idea of ​​the present invention is to determine the coverage rate and / or success rate of the offline positioning data by using the online positioning log and the offline positioning database at the server side, so as to measure the quality of the offline positioning data. Furthermore, the method for determining the offline positioning data can be adaptively adjusted according to the quality of the offline positioning data.

[0049]The online positioning log involved in the embodiment of the present invention refers to the behavior record of positioning using the online positioning method. The online positioning mode mainly includes base station positioning and wifi positioning. Therefore, the online positioning log may include: the...

Abstract

The present invention provides a method and device for determining the quality of offline positioning data, wherein the method includes: using the online positioning log and offline positioning data of the server to determine the coverage and / or success rate of the offline positioning data; wherein the determination of the coverage includes: : Count the total number of records X in the set time period in the online positioning log, and count the number of records Y of the LAC identification information in the set time period in the online positioning log in the offline positioning database, determined by the ratio of Y to X The coverage rate of offline positioning data; the determination of the success rate includes: counting the total number of records X in the set time period in the online positioning log, and counting the number of consistent positioning results in the online positioning log with the offline positioning data within the set time period Z, using the ratio of Z to X to determine the success rate of offline positioning data. The present invention measures the quality of offline positioning through the coverage rate and / or success rate of offline positioning data, so as to play a guiding role in the optimization of offline positioning data.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of computer applications, in particular to a method and device for determining the quality of offline positioning data. [0003] 【Background technique】 [0004] With the continuous popularization and development of mobile devices, more and more users use mobile devices for communication, information acquisition, entertainment and even work. When a user enjoys a service of a mobile device, a demand for positioning of the mobile device is often involved. Currently, the commonly used methods for positioning a mobile device are mainly GPS (Global Positioning System, Global Positioning System) positioning and base station positioning. Among them, GPS positioning requires that the mobile terminal has a GPS module, and the position of the mobile device is often unable to be positioned when it is blocked. Base station positioning means that the mobile device sends the base station ID (identification) to th...
