1. A contact tracking method, comprising:
obtaining positioning information of a plurality of user equipments (UEs), wherein the plurality of UEs transmit wireless signals, the positioning information is determined based on the wireless signals, and the wireless signals indicate one of a network provider identifier, a signal strength, and geolocation;
recording travel routes of the UEs, wherein each of the travel routes records the positioning information of one of the UEs over time; and
analyzing the travel routes of the UEs to determine a contact situation between a plurality of first UEs and a second UE of the UEs based on a contact criteria, comprising:
providing the travel routes of the first UEs, to generate contact lists of the first UEs;
providing a risk value for one of the UEs, wherein the risk value is related to a duplication of the travel routes, and
in response to the second UE appearing on more contact lists of the first UEs with a higher duplication, the second UE has a higher risk value.
