Embodiment Construction

[0056] Before further describing the implementation details of the present invention, firstly, the operation mode of the enhanced coordination function will be described in detail. Please refer to Figure 1; taking the enhanced coordination function of a wireless network under IEEE 802.11e as an example, Figure 1 illustrates the situation where different traffic categories in the same station compete with each other for network media access rights under the IEEE 802.11e specification; Figure 1 The horizontal axis of 1 is time. As shown in Figure 1, before a station A sends its information to the (wireless) medium in the form of frames, its frames can be divided into four traffic categories TC1 to TC4 (respectively called in IEEE 802.11e) according to application requirements. VO, VI, BE, BK). As discussed above, in order to coordinate the media access rights of each traffic class, each traffic class competes for the media access right with the inverse of the corresponding rand...

Abstract

The invention discloses a method and relevant apparatus for implementing network media access control. In network system of wireless media IEEE802.11e, information frames transferred to media by a station are divided into multiple types of flux to make frames in pointed types possible to be transferred to media with high opportunity. Before transferring frames to media, the method reads the frames from storage of system by using media access control circuit in station through inner access. Based on priority of accessing network media of each type of flux set up in advance, inner access circuit reads each frame in sequence. Thus, the invention reduces complexity of media access control circuit, and area of layout.

Description

technical field [0001] The invention relates to a method and a related device for realizing network media access control, in particular to a network media access control method and a related device which can be realized with a simplified circuit. Background technique [0002] The network system can use network media to connect various network members (terminals), so that each network member can contact, communicate, and quickly exchange data, materials, files and audio-visual information. Therefore, the network system has become an indispensable part of the modern information society. missing link. In recent years, due to the maturity of radio technology, wireless networks that can use wireless media architecture to get rid of physical network lines are booming. For example, wireless networks based on the IEEE 802.11 protocol have become increasingly popular. How to deploy a network system at a lower cost has also become one of the focuses of modern information industry re...
