If while occurring in system that a large amount of STA needs to be associated with AP simultaneously, because each STA association process needs repeatedly channel competition, it is congested that serious collision problem can cause system to occur, and needs long time just can complete the association process of all STA.Especially in the time that situation occurs below, AP may run into a large amount of STA needs simultaneously associated scenes:
1) transmission line power breakdown causes intelligent grid equipment, transducer or intelligent gauge equipment etc. to restart in a large number;
2) AP power supply is reset, and to cause all devices and AP to lose associated.
Meanwhile, because the STA of a large amount of transducers or intelligent electric meter class is operated in lower speed, for example 100kbps, the information interaction frame length of association process is longer, and in the time there is concealed nodes in system, the probability of collision can further increase.If occur in BSS that a large amount of STA need association simultaneously, hundreds of to the thousands of STA time association process need to spend dozens of minutes even the longer time just can complete to a few hours.For the higher emergency services type of delay requirement, cannot meet business demand long correlation time in this case.
Similarly, in system work process, the existence of a large amount of STA also can make the increase of collision probability, thereby causes access delay to increase.And repeatedly re-transmission and long time delay that collision causes all can increase the probability that packet is dropped.These problems can have a strong impact on service quality and the reliability of emergency services type.
Certainly,, except emergency services type, there is similar problem for other particular type of service simultaneously.Therefore, be badly in need of a kind of scheme, to improve service quality or the reliability of emergency services type or other particular type of service.
