Abstract: In a process for a wireless network device in a first Neighbor Awareness Network device cluster (NAN cluster) to join a second NAN cluster, the wireless network device first discovers the second NAN cluster by means of scanning for networking signals from the second NAN cluster. If it determines, based on the attribute information of the second NAN cluster, to join the second NAN cluster, the wireless network device sends an event message to other wireless network devices in the first NAN cluster. The event message also contains a cluster ID (CID) of the second NAN cluster. The wireless network device joins the second NAN cluster, wherein the step of joining comprises: performing service discovery in the second NAN cluster instead of performing service discovery in the first NAN cluster.

Abstract: An information query method, including sending, by a first device, a data-excluded information query request frame, where the data-excluded information query request frame includes first control information and a first hash value; receiving, by the first device, a data-excluded information query response frame sent by a second device. The data-excluded information query response frame includes second control information, a second hash value, and an address of the second device. The method also includes sending, by the first device, a data-contained information query request frame to the second device when the first device determines that a third hash value is consistent with the second hash value, so that the second device responds to the data-contained information query request frame when receiving the data-contained information query request frame. Correspondingly, the present disclosure further provides a related device.

Abstract: A method and an apparatus for handling an address conflict. The method for handling an address conflict includes: acquiring a media access control (MAC) address of an associated first node and a first auxiliary identifier; receiving a MAC frame that carries the first auxiliary identifier; and sending an auxiliary identifier conflict report message to the first node when it is determined that the MAC frame is sent by a second node. According to the method and the apparatus for handling an address conflict in the embodiments of the present invention, the following problem can be detected and resolved. An AP auxiliary identifier conflict is caused by a MAC header compression method where an auxiliary identifier is used to replace a MAC address.
