FIELD: radio engineering, communication.
SUBSTANCE: method and device for selecting the tethering wizard, are disclosed at embodiments of the present invention, which can maintain the time synchronization between the devices in the cluster NAN. The method includes: receiving the frame NAN Beacon by the device, wherein the frame NAN Beacon carries the first information AM and the first information TSF, the first information AM includes: the first AMR, the first HC and the first AMBTT; if the frame NAN Beacon is used to select the AM, when the first AMR is less than the second AMR, and the device MR is larger than the first AMR, switching the device role for the AM by the device, wherein the second information AM, recorded in the device, includes: the second AMR, the second HC and the second AMBTT; and if the frame NAN Beacon is used to select the AM, when the first AMR is less than the second AMR, and the device MR is less than the first AMR, updating by the device according to the frame NAN Beacon of the second information AM and the second information TSF, which are recorded in the device.
EFFECT: possibility of realizing the time synchronization between the devices.
