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 discovery information, to join the second NAN cluster, the wireless network device sends an event message to other wireless network devices in the first NAN cluster to inform them that it is leaving the first NAN cluster to join the second NAN cluster. The event message also contains a cluster ID (CID) of the second NAN cluster. The wireless network device then leaves the first NAN cluster and joins the second NAN cluster.

Abstract: A resource reservation method applied to a WiFi system includes: receiving, by a destination node, a resource reservation request sent by a source node, and sending a resource reservation response to the source node, where the resource reservation response includes a reservation time, and the resource reservation response is used to enable another node, which can monitor the resource reservation response, in the WiFi system to set a network allocation vector of the another node according to the reservation time; determining, by the destination node, whether data sent by the source node is received within a predetermined time; and if the data is not received, sending a resource release instruction, so that the another node initializes the network allocation vector of the another node, and re-contends for a resource, thereby solving a hidden node problem and also ensuring that a network resource is fully and properly used.

Abstract: Embodiments of the present invention disclose a method for updating a group temporal key, a related apparatus and system. A method includes: An access point AP sets an updating period of a group temporal key GTK; the access point updates the GTK whenever the updating period of the GTK arrives; the access point receives a GTK request that is sent by a mobile station STA in an association list within a preset delay time period after arrival of the updating period of the GTK, where the association list records all mobile stations communicating with the access point, and the preset delay time period is shorter than the updating period of the GTK; and when the preset delay time period after the arrival of the updating period of the GTK arrives, the access point sends the updated GTK to the mobile station in the association list according to the GTK request.
