Embodiment 1

[0047] Such as figure 1 As shown, the embodiment of the present invention provides a wireless network transmission control method, including:

[0048] S101. The wireless gateway regularly checks whether it has a sending and receiving identifier of the data message.

[0049]The wireless gateway regularly checks whether it has the sending and receiving identification of the data message, which is to check whether the transmission channel of the wireless gateway data message is idle. Indicates that the channel is idle and can be used to send data packets or signaling query packets in the future. For example: when the wireless gateway is receiving the data message sent by the wireless node A or the wireless gateway is sending the data message to the wireless node B, at this time the wireless gateway has a sending and receiving identifier, and the wireless gateway is in a busy state, and needs to wait for the wireless gateway to finish processing After the data message is sent or...

Embodiment 2

[0076] Such as figure 2 As shown, the embodiment of the present invention also provides a wireless network transmission control system, including: a wireless gateway 101 and a plurality of wireless nodes 102; the wireless nodes 102 form a star network through the wireless gateway 101.

[0077] Wireless gateway 101 regularly checks whether self has the sending and receiving identification of data message; The gateway 101 sends a signaling query message to all wireless nodes 102 in a broadcast manner.

[0078] After the wireless node 102 receives the signaling inquiry message, after the self-number of the wireless node 102 is sequentially offset by the preset duration, it sends the signaling response message to the wireless gateway 101 in order to report whether it has a data message to be sent; The wireless gateway 101 receives the signaling response messages of all online wireless nodes 102, selects the wireless nodes 102 that have data messages to be sent in turn, and sends...

Abstract

The invention provides a wireless network transmission control method, including: the wireless gateway checks whether there is a sending and receiving identifier of the data message; when there is no sending and receiving identifier, the wireless gateway checks whether there is a data message to be sent; when there is no data message to be sent , the wireless gateway sends a signaling query message to all wireless nodes by broadcasting; after the wireless node receives the signaling query message, it sends a signaling response message to the wireless gateway in order to report whether it has a data message to be sent ;The wireless gateway receives the signaling response message of all online wireless nodes, selects the wireless node with data message to be sent, sends the signaling confirmation message to the wireless node, and gives the data message sending authority; the wireless node starts to send data message, after the data message has been sent, the wireless node closes its permission to send the data message and sends a signaling end message to the wireless gateway. This method can effectively improve transmission efficiency and reduce file transmission delay.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a wireless network transmission control method and system. Background technique [0002] In a star wireless network environment, wireless nodes communicate through wireless gateways. The wireless gateway is used as the central node; since the wireless gateway and the wireless node have only one channel available in most cases, channel contention conflicts are prone to occur, resulting in high file transmission delay and low transmission efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a wireless network transmission control method to overcome the shortcomings of the prior art. [0004] Specifically, the present invention proposes the following specific embodiments: [0005] An embodiment of the present invention provides a wireless network transmission control method, including: [0006] The wireless gateway r...
