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. It calculates a first score based on multiple pieces of attribute information of the first NAN cluster, and a second score based on multiple pieces of attribute information of the second NAN cluster, compares the first score and the second score, and determines to join the second NAN cluster when the second score is greater than the first score. Then it sends an event message to other wireless network devices in the first NAN cluster to inform them to join the second NAN cluster, stops participating in the first NAN Cluster by not contending for serving as a synchronization device in the first NAN Cluster, and joins the second NAN cluster.

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.
