Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the rate set control flow schematic diagram that the present invention is based on Atheros chip.
Refer to Fig. 1, the rate set control method based on Atheros chip provided by the invention comprises the steps:
Step S1: provide 802.11b/g/a speed set configuration item in user interface, and described 802.11b/g/a speed set configuration item is divided into pressure rate set and the supporting rate collection that there is no common factor; User UI interface can show corresponding rate set options according to current wireless pattern, is mainly divided into tri-kinds of 802.11b/g/a.Be embodied in, 802.11b is used a rate set, and 802.11g, 802.11b/g, 802.11b/g/n, 802.11n only (2.4G) share a rate set; 802.11a, 802.11a/n, 802.11n only (5G) share a rate set.User, by choosing the rate set options of demonstration, carries out the selection of speed and controls.After user configures in UI interface, the rate term of the beacon message that WAP (wireless access point) is sent will show according to corresponding pressure rate set and supporting rate collection.
When user selects, force rate set must have selection, supporting rate integrates can be as sky.The selection of two rate set can not have common factor, otherwise the speed that the rear meeting arranging arranges before removing is selected.
Step S2: the speed set that radio management message and data message are supported is set respectively; The transmission rate of described radio management message is set to force the minimum speed limit value in speed set and supporting rate set; Described data message comprises unicast data message and multicast data message, and described unicast data message and multicast data message are preset with default rate value configuration item; Described pressure rate set is preset with default rate value configuration item.
Rate set control method based on Atheros chip provided by the invention, under centralized wireless networking mode, adopt a functions of wireless middle controller (AC) to connect a plurality of WAP (wireless access point) (TAP), in the user interface of functions of wireless middle controller, unification arranges 802.11b/g/a speed set configuration item and is handed down to each WAP (wireless access point).After each WAP (wireless access point) is restarted, described functions of wireless middle controller is automatically communicated by letter and is issued 802.11b/g/a speed set configuration item to described WAP (wireless access point) by CAPWAP, and comes into force.Under distributed wireless networking mode, a plurality of WAP (wireless access point) (FAP) are directly connected to the network of cable convertor, and 802.11b/g/a speed set configuration item is set respectively in the user interface of each WAP (wireless access point), restart rear preservation.
Fig. 2 is that the rate set that the present invention is based on Atheros chip is controlled detail flowchart.
Please continue referring to Fig. 2, user logs in UI interface, first determines wireless mode, then chooses corresponding pressure rate set and supporting rate collection according to options, clicks confirming button.Selective rule is to force rate set and supporting rate collection cannot have common factor, forces rate set to select, and supporting rate collection can not select.
WAP (wireless access point) upper strata receives after the rate set data of this user's selection, can write a structure, forms the Speedometer Drive that a user arranges.This structure is divided into three parts, a recording rate number, and an array of preserving rate set numerical value, also has the array of the attribute (force/support) that save value is corresponding.Array is preserved according to order from small to large according to speed size, maximum 15.
Communicate by letter by ioctl in WAP (wireless access point) upper strata, the Speedometer Drive that user is arranged is passed to wireless driving.
Wireless driving itself, preserves the default rate table that each wireless mode is supported.The Speedometer Drive that wireless driving meeting arranges user and the default rate table under current wireless pattern are got common factor, form new Speedometer Drive.If new Speedometer Drive is not empty, using new Speedometer Drive is final Speedometer Drive; Empty if, using the default rate table under current wireless pattern is final Speedometer Drive.But during UI interface is selected before, forcing rate set can not be sky, so this gets common factor, is can not be sky in theory.
During selected administrative message speed, use first of final Speedometer Drive obtained above.While generating beacon bag, final Speedometer Drive obtained above is added.Data message speed is selected certain value in final Speedometer Drive, by wireless terminal and WAP (wireless access point), is consulted, and gets the common factor of both supporting rates.
In sum, rate set control method based on Atheros chip provided by the invention, on user UI interface, realize the control of speed, only realizing conventional rate collection controls, 11n speed does not process, solved in the situation that speed can not join, in complex environment, because speed is low, affected the problem that performance and user experience.The rate set option that has current wireless pattern to support on user UI interface, is divided into and forces speed set supporting rate collection.User, by choosing, realizes the control to speed.Selective rule is to force rate set to select, and supporting rate collection can be sky, but the two can not have common factor.The minimum speed limit value of forcing in rate set and the set of supporting rate collection for administrative message, data message is for forcing any one rate value in rate set and the set of supporting rate collection.
Although the present invention discloses as above with preferred embodiment; so it is not in order to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little modification and perfect, so protection scope of the present invention is worked as with being as the criterion that claims were defined.
