"Communication Big Data Travel Card" analyzes "mobile phone signaling data", which needs to be obtained through the location of the base station where the user's mobile phone is located. The collection, transmission and processing of signaling data are automatic, with strict security and privacy protection mechanisms, and the query results are available in real time, which is convenient and fast. Therefore, if the user goes out without a mobile phone, the mobile phone can only collect information located at home, and there will be no change.
In addition, in order to ensure communication continuity, realize coverage without blind areas and provide better communication service quality, the signals of the base stations in the two places at the junction of administrative divisions may cross-cover, resulting in deviation of the results.
Therefore, if the management department encounters the situation that the user's query results are inconsistent with the actual itinerary during the itinerary inspection, it can comprehensively judge the inspection results by combining the air tickets, air tickets or other supporting materials provided by the users.
