Abstract
A contact tracking method and a related server are provided. In the method, the positioning information of multiple user equipments (UEs) is obtained. The UEs transmit wireless signals. The positioning information is determined based on the wireless signal. The wireless signal indicates a network provider identifier, a signal strength, or geolocation. The travel routes of the UEs are determined. Each travel route records the positioning information of one UE over time. The travel routes are analyzed to determine a contact situation between a first UE and a second UE of the UEs based on a contact criteria.
