Why is the communication big data trip query not recorded?

Travel information can't be found in the travel card of communication big data, mostly because the phone is used in different places, or the location of the base station at the junction of the two places is problematic according to the mobile phone card. This may happen if the user lives near the city boundary or travels long distances by car or train.

If you find that you can't find travel information in the travel card of communication big data, check whether the distance from 20 o'clock is more than 4 hours at the first time. If it exceeds, call immediately, preferably for more than 3 minutes. If not, try again the next day. 1 day, it is best to have 5 calls, with an interval of 1 hour or 1.5 hours. Before 20: 00 on the same day, the interval between the first call and the last call exceeded 4 hours.

Travel card calculation was completed in the background of the operator, and the result was delayed by one day. For example, the travel data calculated on March 5th is before March 4th 14 days. In addition, because the service uses base station data, in order to ensure continuous communication and achieve no blind area coverage, the base station signals at the junction of administrative divisions may cross-cover, resulting in deviation of the results, so it can be adjusted according to other certificates.
