To achieve these goals, for the relay of WLAN (wireless local area network), WLAN (wireless local area network) relay of the present invention comprises following part: according to the storage part of the interim memory communicating data that net transmits of control signal; Monitoring in real time is connected the power supply status of several terminals on the communications zone, and the data that the power supply status terminal less than critical value is received are stored in storage part temporarily, and to it control part of controlling.
In addition, for the trunking method of the relay of WLAN (wireless local area network), WLAN (wireless local area network) trunking method of the present invention comprises following step; (a) several terminals of carrying out wireless telecommunications receive the step of each power state information; (b) step of the data that receive according to the interim memory communicating net of the power supply status of receiving terminal.(c) data of above-mentioned interim storage greater than set big or small the time, send the step of receiving terminal to.
Effect of the present invention:
As mentioned above, in the relay and method thereof of WLAN (wireless local area network) of the present invention,, and store the reception data according to the residual amount of the battery of communication device and transmit then because relay is provided with a certain size buffer, therefore can improve the effect of communication device conserver power source
In addition, the relay of aforesaid WLAN (wireless local area network) of the present invention and method thereof have following effect: the AP of the relay of wireless local area network (WLAN) system is provided with a certain size buffer, residual amount handle according to the communicating terminal power supply receives storage in buffer, send communicating terminal then to, therefore can carry out the elasticity management the terminal power supply.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.

Embodiment
Below just the relay of WLAN (wireless local area network) of the present invention and the execution mode of method thereof are illustrated in more detail with reference to accompanying drawing.
Just, the detailed description of omitting in the process of the present invention for the known part of prior art is described.
Fig. 2 is the AP structure calcspar of embodiments of the invention.
If with reference to Fig. 2, the AP (Access Point) 200 of performance WLAN (wireless local area network) relay effect comprises following components: be used for communication network and data and transmit the data transmission acceptance division 210 that receives; Transmit the storage part 220 of acceptance division 210 received data according to the above-mentioned data of the interim storage of the residual amount of the battery of wanting receiving terminal; And can carry out the wireless telecommunications portion 230 that carries out wireless telecommunications between the terminal of wireless telecommunications; The residual amount information of battery of the above-mentioned terminal of verification is stored in storage part to the data that receive according to the residual amount of the battery of terminal then temporarily in real time, and to it control part of controlling 240.
The data that 210 pairs of communication networks of data transmission acceptance division send terminal to receive, and the data that terminal is transmitted convey to communication network.
When the terminal that will receive the data that communication network transmitted is provided with battery less than critical value, just store in the storage part 220, till reaching certain size for conserver power source temporarily.
Carry out wireless telecommunications between wireless telecommunications portion 230 and the terminal, control part 240 receives the residual amount information of each battery that several terminals transmitted of carrying out WLAN communication by AP200, data transmit acceptance division 210 at the end cell that will receive the data that communication network receives during less than critical value, temporarily storage till storage part 220 is when becoming a certain size, and it is controlled.Several terminal periodic ground on the above-mentioned communications zone that is connected relay receive power state information.
In addition, when ephemeral data is stored, the cycle of power conservation pattern can elongated message be transmitted informs to relevant terminal, if a certain size storage is in storage part 220, the disposable whole transmission of the data of relevant terminal storage, because last data are transmitted, therefore just the message that requires to reenter the power conservation pattern is sent to relevant terminal then.
To the action of the AP of the above-mentioned embodiment of the invention be described in detail below.
Fig. 3 is the precedence diagram of the AP method of operating of the embodiment of the invention.
Step 301, if with reference to Fig. 3, as shown in Figure 2 AP200 in real time the terminal from the communication district receive battery information.
Step 302 confirms whether communication network will be received to the data that terminal transmits.
Step 303, the data that communication network will transmit to terminal if present, AP confirms to receive the end cell information of relevant data, judges whether to possess the residual amount of battery less than having set in advance critical value then.
Step 304, if receive the residual amount of the end cell of above-mentioned data less than critical value, AP200 in storage part 220, if received data have been stored as greater than a certain size, sends the message that will transmit storage to will receive above-mentioned data terminal.At this moment, AP200 still sends elongated message of power conservation (Power Saving) cycle to terminal.
Terminal makes the power conservation cycle elongated according to the message of above-mentioned AP200, therefore can obtain bigger power savings.
Step 305 judges whether it is greater than setting big or small storage in storage part 220.
Step 306, if greater than a certain size storage at storage part 220, AP200 informs greater than the data of setting size to terminal and is stored.
Step 307, terminal receives the signal that is called awakening mode then.
Step 308, terminal receives and is called after the signal of awakening mode, and the wireless telecommunications portion 230 of AP200 is the disposable terminal that sends to of the data of storage part 220, after transmission is all over, owing to transmitted final data, therefore also will transmit and inform the end that reenter the power conservation pattern.
Step 309, in addition, in step 303 if the end cell that receives data greater than critical value, data directly send relevant terminal to.
As mentioned above, when AP200 transmits data owing to be: the residual amount with battery is a standard, data to the terminal transmission that has the residual amount of a small amount of battery, till becoming a certain size, can be stored in other storage part 22 0 always, carry out disposable transmission then, therefore can reduce the consumption of end cell.
The WLAN (wireless local area network) relay of the embodiment of the invention and method thereof are distinguished and are applicable to that the data of the wireless communication terminal battery status that receives data transmit the priority picks, it is characterized in that improving the elasticity management of power supply.Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
