  • Patent number: 10101434
    Abstract: Embodiments provide a positioning method, a control device, and a mobile communications system. A control device receives a first positioning measurement parameter used for positioning a user equipment (UE). The first positioning measurement parameter is received through one communications system interface or multiple communications system interfaces among N communications system interfaces supported by the control device. The control device positions the UE according to the received first positioning measurement parameter.
