Embodiment Construction

[0046] figure 1 It is a structure diagram of a wireless local area network in a preferred embodiment of the present invention, wherein the wireless local area network 100 includes a plurality of basic service areas 106,107. A basic service area 106 includes a wireless access point 102 and a limited number of mobile stations 101 (mobile stations, stations for short, devices with wireless communication functions, such as mobile phones 103, PDAs 105, notebook computers 104, etc.). Each mobile station can be in active mode or power saving mode. A mobile station in a power saving mode is called a power saving mobile station. Power Saving The mobile station can save power consumption by entering a doze state. Each mobile station can only associate with one wireless access point or reassociate with another wireless access point, and become a member of the basic service area. Once the association or re-association is successful, the wireless access point will give the mobile stati...

Abstract

A method for controlling media access includes priority processing program of utilizing message frame interchange mode to ensure that mobile station with high priority can add in polling name list before mobile station with low priority, collision analyzing program of utilizing tree shaped dividing calculation to let mobile station passed priority processing add in polling name list within limited time and polling program of making radio access point execute scheduling calculation to let mobile station in polling name list to transmit data in sequence according to line polling message frame command of vector string.

Description

technical field [0001] The invention relates to a medium access control (MAC for short) method, which is suitable for wireless area networks and can provide service quality assurance and power saving effects. Specifically, the method of the present invention simultaneously supports functions such as multiple priorities, fast control right reservation, dynamic bandwidth allocation, admission control, and power management. Background technique [0002] With the popularity of portable computers and the advancement of wireless modulation (modulation) technology, more and more multimedia applications expect WLAN (wireless local area network) communication protocols to support QoS. The basic service area (basicservice set) of a WLAN usually includes a wireless access point (accesspoint, generally translated as a wireless access point or a wireless bridge) and a limited number of mobile stations (station for short, It is a device with wireless communication function, such as: mobi...
