Problems solved by technology

[0013] The current mechanism often controls whether to enable the RTS / CTS mechanism or the CTS-To-Self mechanism through the packet size threshold setting. Therefore, if the space medium is very busy and the conflict is serious, the network quality cannot be improved in a timely and effective manner through the RTS / CTS mechanism and the CTS-To-Self mechanism.

Embodiment Construction

[0055] As mentioned in the background technology, the existing setting of the packet size threshold to control whether to enable the RTS / CTS mechanism or the CTS-To-Self mechanism is not flexible enough in actual use, and, in a high-density deployed WLAN network, due to space The environment and applications are constantly changing. Therefore, according to the existing control mechanism, it is impossible to timely and effectively judge whether to enable the RTS / CTS mechanism and the CTS-To-Self mechanism for packet transmission processing, which affects the quality of network transmission.

[0056] In order to solve the above problems, the present invention proposes a network address translation message sending method. In actual WLAN applications, the space media channel occupation and message retransmission are effectively considered, and the channel reservation mechanism is dynamically enabled and stopped. Reduce space medium conflicts and improve wireless network stability a...

Abstract

The invention discloses a method and a device for message transmission. By employing channel occupying parameters and message retransmission parameters as adjustment references, message transmission treatment is conducted by dynamically enabling a channel reservation mechanism to work and stop working; accordingly, when in severe spatial environment and busy time, the channel reservation mechanism of an RTS/CTS mechanism or a CTS-To-Self mechanism is reasonably used to transmit messages; the method decreases use conflicts of system resources and improves WLAN network application quality.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message sending method and device. Background technique [0002] Wireless local area network (Wireless Local Area Network, WLAN) provides a wireless connection service of local area network, which can provide high-speed wireless data access in a small range, and is currently a popular technology in the information technology (Information Technology, IT) industry. One of the technologies is also a popular wireless access method. [0003] An access point (Access Point, AP) is an important component device of a wireless local area network, and is a wireless transceiver device. Data received through a wired network (for example, the Internet) can be converted into wireless signals and sent to terminals or other network devices, and the received wireless signals can be converted into data and forwarded to the wired network. [0004] The request to send / clear to send...
