Problems solved by technology

According to the existing rules, when a node in a cluster receives a Sync Beacon frame from AM, if the AnchorMaster Rank (AMR) in the Sync Beacon frame is smaller than the AMR recorded by most nodes in the cluster and their own MR, and The Medium Access Control (MAC) address information in the Sync Beacon frame is equal to the MAC address information of the AM recorded by the node itself, so most of the aforementioned nodes may change their roles to become AM in a short period of time, resulting in short-term A large number of Sync Beacons need to be sent internally, which consumes too much air interface resources

Abstract

The present invention provides a method, node and device for controlling the transmission of beacon frames. The method is used in a proximity-aware network, including: a first node receives a first synchronization beacon sent by a second node in the proximity-aware network frame, the first synchronization beacon frame carries the first anchor master information, the anchor master information in the first node includes the second AMR, wherein the second AMR includes the second MAC address information; when the first AMR is smaller than the second AMR, the first AMR The MAC address information is the same as the second MAC address information, and when the master node willingness value MR of the first node is greater than the first AMR, the first node updates the anchor master information in the first node according to the first anchor master information; When the preset node state of the first node is in a synchronous state, the first node sends a second synchronization beacon frame; or, when the default node state of the first node is in an asynchronous state, the first node does not send a synchronization beacon frame frames, thereby solving the problem of excessive consumption of air interface resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, node and device for controlling the sending of beacon frames. Background technique [0002] At present, social networking and localization have become the mainstream modes in the mobile Internet industry, especially with the popularization of mobile nodes equipped with Wireless-Fidelity (Wi-Fi) interfaces, Wi-Fi technology periodically sends information through central nodes. Beacon frame, so that external nodes can be associated with the central node. However, the network structure and data transmission in the 802.11 protocol are limited. For example, when there is no central node, it is difficult to perform discovery services. Currently, the Neighbor Awareness Networking (NAN) mechanism is generally used to solve this problem, making multiple A NAN composed of NAN nodes is a NAN cluster (Cluster). Nodes in the same NAN cluster have the same clu...
