Extended data:
"Communication Big Data Travel Card" analyzes the signaling data of the mobile phone, which is obtained through the base station where the user's mobile phone is located. The collection, transmission and processing of signaling data are highly automated, with extremely strict security and privacy protection mechanisms and high authenticity and accuracy.
The "Communication Big Data Travel Card" service uses base station data. In order to ensure continuous communication and achieve no blind area coverage, the signals of base stations in the two places at the junction of administrative divisions may cross-cover, resulting in deviation of results. In addition, staying in a city for less than 4 hours will not be recorded.
The "travel card" analyzes the signaling data and bill data of the mobile phone, so the premise of having travel data is that the user generates these signaling and bill data in the process of using the mobile phone. In this case, you can try to make a few more calls, or turn off the Wi-Fi connection and use 4G traffic, and you can find the data the next day without any problems.
