  • Patent number: 10895625
    Abstract: A computer-implemented method and a server for device positioning. The computer-implemented method includes receiving a control message from a positioning server. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. At least one measurement of a signal from at least one of a reference device for the area and a target device is obtained, according to the control message, with the reference device being located at a predefined position with respect to the area. The at least one measurement is reported to the positioning server for determining a position of the target device with respect to the area.

  • Publication number: 20190178977
    Abstract: A computer-implemented method and a server for device positioning. The computer-implemented method includes sending a control message to a detector. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. A measurement of a signal from a device for the area and a target device is received from the detector. Position of the target device with respect to the area is determined based on a measurement and a radio map. The radio map indicates signal strength corresponding to positions in the area.

  • Patent number: 9859989
    Abstract: A method for processing interference in wireless communication at a base station, wherein at least some of a plurality of (Radio Frequency) RF channels in the base station operates at a current operating frequency point assigned to the base station includes detecting interference of one or more candidate frequency points by using at least one RF channel, wherein the one or more candidate frequency points are different from the current operating frequency point; reporting result of detecting interference of the one or more candidate frequency points to a resource manager; and in response to the resource manager assigning one of the one or more candidate frequency points to the base station, notifying a user to switch from the current operating frequency point to the assigned candidate frequency point.

  • Patent number: 9826339
    Abstract: In one embodiment, a system includes a first tracked device and a second tracked device. The first tracked device includes first known device data, describing one or more previous connections known to the first tracked device. The second tracked device includes second known device data, describing one or more previous connections known to the second tracked device. The first tracked device is configured to connect to the second tracked device, transfer to the second tracked device at least a portion of the first known device data, and receive from the second tracked device at least a portion of the second known device data. The first tracked device is further configured to modify the first known device data to incorporate the second known device data. The second known device data includes data related to a previous connection involving a third tracked device outside a signal range of the first tracked device.
