Description

A kind of instruction method for message transmission to be received and device Technical field
The present invention relates to the communications field, more particularly to a kind of instruction method for message transmission to be received and device.
Background technology
In a wireless local area network, for power saving, website typically operates in battery saving mode, when site works are in battery saving mode, and its working condition replaces conversion according to certain rule between revival (Awake) state and sleep (Doze) state.When in Doze states, the electric quantity consumption of website can drop to very low, but can not receive the message of access point transmission.
In order that the data of arrival can be sent to website as early as possible by access point in time, current Wireless Fidelity (WiFi, WIreless-FIdelity) data transfer indicates figure (TIM, Traffic Indication Map) downlink data transmission mechanism defined in 802.11 standards.According to TIM mechanism, working in the website of battery saving mode needs periodically to revive, and to receive the TIM fields in the broadcast message of access point broadcast, the broadcast message that access point passes through periodic broadcast, the data latency for indicating whether caching to website is sent to website.Specifically, TIM fields are made up of some binary digits, the sequence number of each binary digit and the association identification (AID of website, Association identifier) correspondence, when a certain position is set to 1, representing corresponding AID website has the data of caching in access point, when website finds to have the data of caching in access point by broadcasting the message, just after the broadcast message is received, in idle channel power-save poll (PS-Poll is sent in the way of free competition to access point, Power Save poll) instruction message to be received, it is then in wake states, the data issued etc. access point to be received, the sleep state of power saving is entered back into after data until having received.
In the prior art, multiple indicating bits in TIM can be set to " 1 " by access point, the data for having caching are indicated to multiple websites simultaneously, at this moment multiple websites will send PS-Poll message to access point in the way of free competition channel simultaneously, wherein, the substantially flow of channel free competition mechanism is：Whether website first intercepts channel idle, if idle time of channel exceedes certain time (such as AIFS, arbitration interframe space, arbitrate frame period), website then starts an avoidance mechanism, randomly choose a back-off value between the minimum back off time and maximum back off time of setting (in units of Time slot), start a countdown timer clock simultaneously (in units of Time slot), when the back-off value of website selection is had reached between when the channel is idle, then countdown timer clock is kept to 0, trigger website and send PS-Poll message to access point.
It is can be seen that by above-mentioned channel free competition process when two websites have randomly choosed identical back-off value by chance, the PS-Poll message collisions that the two websites will be caused to send simultaneously, website will re-start channel competition in this case.Because the channel competition of multiple websites is carried out on entirely access point working channel, it is clear that the conflict of PS-Poll message necessarily causes the waste of whole channel resource.
