Abstract: A cell search method and a communications apparatus are provided. The method includes the following: before searching for a cell, a terminal device may determine, with reference to historical access information of another terminal device, whether there is a cell at the location, and adjust, based on a determining result, a value of a search parameter used to search for a cell. For example, if there is a cell, the terminal device may adjust the search parameter to accelerate a search. If there is no cell, the terminal device may perform no search, or adjust the search parameter to reduce an unnecessary cell search performed by the terminal device, so that power consumption of the terminal device can be reduced.

Abstract: Embodiments of the present invention relate to the communications field, and provide a method for sending a sync beacon message by a NAN device, and a device, so as to resolve a problem of a sync beacon message conflict that occurs when the NAN device merges to a new cluster in a master role. The method is: when a first device in a first cluster receives first cluster information of a second cluster, if the first device determines to merge to the second cluster, sending a sync beacon message in the second cluster according to a role and a state of the first device in the first cluster. According to the embodiments of the present invention, after merging to a cluster, a NAN device determines whether to send a sync beacon frame.
