Below in conjunction with accompanying drawing, the embodiment of distributed channel connection control method of the present invention is illustrated.
Fig. 1 is the schematic flow sheet of the embodiment mono-of distributed channel connection control method of the present invention.As shown in Figure 1, method of the present invention can comprise:
Step S110, the data priority of the data that transmitting according to terminal, searches the transmission queue corresponding with described data priority.
Step S111, according to the user class of described terminal, in the described transmission queue finding out, searches the transmission queue corresponding with described user class;
Step S112, sends in the transmission queue corresponding with described user class finding described in the data that described terminal is being transmitted deposit in.
In specific implementation, before step S110, method of the present invention also can comprise:
Create multiple transmission queues, and set up the type of each transmission queue and the corresponding relation of data priority, and set up transmission queue under all types of and the corresponding relation of user class; The quantity of the transmission queue of each type is at two or more, and multiple transmission queues of same type send the data of same type, the corresponding one or more user classs of each transmission queue in multiple transmission queues of same type.
In specific implementation, the method for the embodiment of the present invention is applicable to various wireless network environments (such as, WLAN (wireless local area network) WLAN).And different from the dividing mode of transmission queue at different net environment data priorities, such as, with reference to figure 7, for EDCA mechanism, the transmission queue of described establishment comprises high priority voice (VO_H) queue, low priority voice (VO_L) queue, high priority video (VI_H) queue, low priority video (VI_L) queue, high priority (BE_H) queue of doing one's best, low priority (BE_L) queue of doing one's best, high priority background data (BK_H) queue, low priority background data (BK_L) queue, the priority of their transmission data from high to low.
Wherein, the type of (VO_H) queue of high priority voice and low priority voice (VO_L) queue is voice (VO);
The type of high priority video (VI_H) queue and low priority video (VI_L) queue is video (VL);
High priority the do one's best type of (BE_L) queue of (BE_H) queue and low priority of doing one's best is do one's best (BE);
The type of (BK_H) queue of high priority background data and low priority background data (BK_L) queue is background data.

Therefore in feasible execution modes more of the present invention, the data priority of the data that transmitting according to terminal, searches the transmission queue corresponding with described data priority; According to the user class of described terminal, in the described transmission queue finding out, search the transmission queue corresponding with described user class; And send in the transmission queue that finds described in depositing in of the data that described terminal is being transmitted.As can be seen here, through after the method flow of the embodiment of the present invention, the data of the terminal of local different user rank transmit by different transmission queues.Make the terminal equipment with high user class can preferentially enjoy channel resource, strengthened the user's of high user class experience.
Fig. 2 is the schematic flow sheet of the embodiment bis-of distributed channel connection control method of the present invention.As shown in Figure 2, method of the present invention can comprise:
Step S210, receives the request of the user class of adjusting described terminal.
Step S211, adjusts the user class of described terminal according to described request.
Step S212, according to the user class after described adjustment, adjusts the distributed channel access parameter of described terminal.
Step S213, will notify described terminal to the adjustment result of user class and distributed channel access parameter, so that described terminal obtains the distributed channel access parameter mating with described user class.
Step S214, the data priority of the data that transmitting according to terminal, searches the transmission queue corresponding with described data priority.
Step S215, according to the user class of described terminal, in the described transmission queue finding out, searches the transmission queue corresponding with described user class;
Step S216, sends in the transmission queue corresponding with described user class finding described in the data that described terminal is being transmitted deposit in.
In specific implementation, before step S210, method of the present invention also can comprise:
Create multiple transmission queues, and set up the type of each transmission queue and the corresponding relation of data priority, and set up transmission queue under all types of and the corresponding relation of user class; The quantity of the transmission queue of each type is at two or more, and multiple transmission queues of same type send the data of same type, the corresponding one or more user classs of each transmission queue in multiple transmission queues of same type.
In specific implementation, the method for the embodiment of the present invention is applicable to various wireless network environments (such as, WLAN (wireless local area network) WLAN).And different from the dividing mode of transmission queue at different net environment data priorities, such as, with reference to figure 7, for EDCA mechanism, the transmission queue of described establishment comprises high priority voice (VO_H) queue, low priority voice (VO_L) queue, high priority video (VI_H) queue, low priority video (VI_L) queue, high priority (BE_H) queue of doing one's best, low priority (BE_L) queue of doing one's best, high priority background data (BK_H) queue, low priority background data (BK_L) queue, the priority of their transmission data from high to low.
Wherein, the type of (VO_H) queue of high priority voice and low priority voice (VO_L) queue is voice (VO);
The type of high priority video (VI_H) queue and low priority video (VI_L) queue is video (VL);
High priority the do one's best type of (BE_L) queue of (BE_H) queue and low priority of doing one's best is do one's best (BE);

Wherein, the speech data of the corresponding one or more user classs of high priority voice (VO_H) queue, the speech data of the corresponding one or more user classs of low priority voice (VO_L) queue; The video data of the corresponding one or more user classs of high priority video (VI_H) queue, the video data of the corresponding multiple user classs of low priority video (VI_L) queue; The do one's best best-effort traffic of the corresponding one or more user classs of (BE_H) queue of high priority, the do one's best best-effort traffic of the corresponding one or more user classs of (BE_L) queue of low priority; The background data of the corresponding one or more user classs of high priority background data (BK_H) queue, the background data of the corresponding one or more user classs of low priority background data (BK_L) queue.Thus, under EDCA mechanism, can there be altogether 8 queues to carry out the transmission of control terminal data.
In specific implementation, in system initialization, each terminal has been assigned with corresponding user class, therefore, but carry out in the process of data transmission in terminal, may adjust for some reason the possibility of the user class of terminal, such as, user may ask to promote or reduce the user class of terminal for the needs of data temporarily, during as network congestion, certain user is willing to pay and obtains higher rate, therefore, user can be by clicking the acceleration button of application program, the request of the user class during thereby transmission raising is described, now, what receive at step S210 is the request that request improves user class, or when set meal has exceeded soon, certain user thinks the interim rate of deceleration, also can click the retard button of application program, request reduces user class to save flow system flow.Therefore, can receive the request of request attenuating user class at step S210.For another example,, in some feasible execution modes, network side also can ask to change user class temporarily, as: Internet resources are limited, in the time that high-priority users is many, need to reduce other users' speed, network side meeting in this time active request reduces the user class of some terminal.Therefore, can receive the request of the user class of the request attenuating terminal of network side transmission at step S210.
In specific implementation, method of the present invention can be completed by access point (Access Point, AP), and now the step S210-S213 of the embodiment of the present invention can complete by the detection process of AP.It is specific as follows:
AP receives and adjusts after the request of user class, and AP changes quality (QoS) version number in next beacon frame (Beacon) message, not the changing of other territory.
All terminals are being received after Beacon, find that QoS version number changes, and can initiate probe requests thereby (Probe request) message to AP according to agreement regulation.
AP is receiving after Probe request, only send probe response (Probe response) and need to adjust the terminal of user class to this, and in Probe response, revise EDCA parameter and user class, make described terminal obtain the distributed channel access parameter mating with described user class, the Probe request message AP of other-end is not responded.
Thus, the terminal of the distributed channel access parameter of the described user class coupling of follow-up acquisition can transmit upstream data by the distributed channel access parameter after adjusting.
In some feasible execution modes, when in the time that step S215 finds described priority query, the method for the embodiment of the present invention also can comprise (not shown):
Described transmission queue current whether still can the store data corresponding with described user class of judgement, if the judgment is Yes, send in the transmission queue corresponding with described user class finding described in the data that described terminal is being transmitted deposit in; If the judgment is No, described in the data that described terminal transmitted deposit in, find out in other transmission queues in the transmission queue corresponding with described data priority and send.
