Embodiment 1

[0219] Such as Figure 4 As shown, it is a schematic diagram of steps of a method for joining a proximity-aware network device group in Embodiment 1 of the present invention, and the method includes the following steps:

[0220] Step 101: A wireless device in a first proximity-aware network device group discovers a second proximity-aware network device group.

[0221] The wireless device may join the first proximity-aware network device group after scanning and discovering the first proximity-aware network device group, and locally record the CID of the joined first proximity-aware network device group.

[0222] After the wireless device joins the first proximity-aware network device group, it can still monitor the beacon frame or service frame of the proximity-aware network on the working channel. The beacon frame can be Discovery Beacon or Sync Beacon, and the service frame can be Service Discovery Frame.

[0223] When the CID contained in the monitored beacon frame or ser...

example 1

[0236] Example 1: The wireless device can compare the CID of the second proximity-aware network device group with the CID of the first proximity-aware network device group, and determine whether to join the second proximity-aware network device group according to a preset decision rule .

[0237] The content of the decision rule determines the moving direction of the wireless device between the first proximity-aware network device group and the second proximity-aware network device group, and then determines the first proximity-aware network device group and the second proximity-aware network device group. The direction of merging between, the determination rules can be set according to actual needs.

[0238] The determination rule may be: when the CID of the second proximity-aware network device group is greater than the CID of the first proximity-aware network device group, it is necessary to join the second proximity-aware network device group. In this step 103, when the w...

example 2

[0241] Example 2: The wireless device can compare the size of the second proximity-aware network device group with the size of the first proximity-aware network device group, and convert the small-scale proximity-aware network device group to the large-scale proximity-aware network device group The merging rule is that when the wireless device determines that the size of the second proximity-aware network device group is greater than the size of the first proximity-aware network device group, it determines that it needs to join the second proximity-aware network device group.

Abstract

Disclosed are a method, device and system for joining a Neighbor Awareness Network (NAN) cluster. When a wireless device in a first NAN cluster scans and finds a second NAN cluster, if joining the second NAN cluster is necessary, then the wireless device leaves the first NAN cluster and joins the second NAN cluster; as the wireless device does not join a plurality of NAN clusters at the same time, the wireless device has low power consumption; in addition, as times goes on, when all the wireless devices in the first NAN cluster leave the first NAN cluster and join the second NAN cluster, the discovery window (DW) of the first NAN cluster on the working channel will not be occupied, thus increasing available resources on the working channel.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method, device and system for joining a Neighbor Awareness Network Cluster (Neighbor Awareness Network Cluster). Background technique [0002] Wi-Fi (Wireless Fidelity, wireless fidelity) technology, as a short-distance wireless communication technology, has been widely used due to its advantages such as free spectrum and high transmission rate. For example, in scenarios where APs (Access Points) are set up in airports, restaurants, and conference rooms, Wi-Fi devices access the network through APs; Direct communication between Wi-Fi devices realizes the sharing of data among Wi-Fi devices and the use of various services, that is, communication between Wi-Fi devices is realized. [0003] For scenarios where APs are not installed, the Wi-Fi Alliance (Wi-Fi Alliance) proposed the NAN (Neighbor Awareness Network) technology to realize synchronization and service discove...
