Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
In WLAN standard, DTIM cycle (DTIM period) territory in the transmission indication information (Traffic Indication Message is called for short) TIM unit (TIM elment) is used to refer to the cycle of the beacon that carries TIM elements.Such as, per four beacons of beacon that carry TIM element occur once, and then DTIM period is set to 4.
Fig. 1 is the schematic flow diagram according to the data transmission method 100 of the embodiment of the invention.As shown in Figure 1, method 100 comprises:
110: obtain the set in DTIM cycle, the set in wherein said DTIM cycle comprises at least one DTIM periodic quantity;
120: send a notification message to STA, wherein said notification message comprises the set in described DTIM cycle;
130: receive the feedback message that described STA sends, wherein said feedback message carries the concrete DTIM periodic quantity that described STA selects from the set in described DTIM cycle.
In the step 110 of this method, AP determines cycle (DTIM period1-DTIM period n) of own support how many kinds of DTIM (DTIM1-DTIMn) and every kind of DTIM, the set in these DTIM general name DTIM cycles according to self ability (as the buffer memory ability etc.).According to the embodiment of the invention, AP can support at least a kind of DTIM cycle.Perhaps, the periodic quantity of each DTIM among a plurality of DTIM that also can pre-defined AP support.For example, a kind of DTIM cycle of AP support is 2 beacons, 4 beacons, 8 beacons.The number in the DTIM cycle that AP can support according to oneself is determined the TIM elment in the beacon, and is routine as shown in table 1:
Wherein Element ID represents the sign of TIM element, and Length represents the length of this TIM element, and DTIM Count k represents that k DTIM also has several beacon frames before arriving.If DTIM count k=0 represents current TIM element frame and comprises the part bitmap mapping (partial bitmap) of a DTIM count k.
Notification message in the step 120 can be AP when related with STA, and AP sends to the notification message of STA.AP tells STA the set in the DTIM cycle that described AP supports by this notification message, comprises at least one DTIM periodic quantity in the set in this DTIM cycle.
STA can suitably select concrete DTIM periodic quantity according to concrete application demand after the set that obtains the described DTIM cycle.For example, for delay sensitive type STA, can select less DTIM periodic quantity, the DTIM periodic quantity of 2 beacons for example, and for battery powered power sensitive type STA, can select long DTIM periodic quantity, for example the DTIM periodic quantity of 8 beacons.And STA notifies AP by feedback message with the concrete DTIM periodic quantity that described STA selects in 130 steps of said method.So, both take into account the different DTIM cycle requirement of delay sensitive type and power sensitive type STA, also simplified the management complexity of AP for multiple DTIM.By limiting the range of choice of DTIM periodic quantity, avoided different STA to select the too wide in range DTIM periodic quantity of distribution, for the application scenarios that comprises a large amount of STA, improved AP to whole Network Management efficient.

140:AP preserves the selected described concrete DTIM periodic quantity of described STA.
AP can be kept at the concrete DTIM periodic quantity that different STA select in the memory space, in order to according to DTIM cycle of each STA, by beacon it is waken up, has carried out transfer of data.
According to the embodiment of the invention, as shown in Figure 3, method 100 can further include step:
150: receive the update inquiry information that described STA sends, wherein said update inquiry information is carried the DTIM periodic quantity of the renewal that described STA selects from the set in described DTIM cycle.
For the STA that supports multiple business, this STA can select new DTIM periodic quantity according to the change of type of service, when for example being transformed into power sensitive type business from delay sensitive type business, can change the DTIM cycle of previous selection by update inquiry information, to adapt to the variation of type of service.
At this moment, method 100 may further include step:
160:AP preserves the DTIM periodic quantity of the selected described renewal of described STA.
Fig. 4 is the angle from STA, the implementation procedure of the data transmission method of the embodiment of the invention.As shown in Figure 4, method 400 comprises:
410:STA receives the notification message that access point AP sends, and wherein said notification message comprises the set in DTIM cycle, and the set in described DTIM cycle comprises at least one DTIM periodic quantity;
420: described STA sends feedback message to described AP, and wherein said feedback message carries the concrete DTIM periodic quantity that described STA selects from the set in described DTIM cycle.
As shown in Figure 5, when the type of service of STA changed, STA can select the DTIM periodic quantity upgraded again by update inquiry information:
430: send update inquiry information to described AP, wherein said update inquiry information is carried the DTIM periodic quantity of the renewal that described STA selects from the set in described DTIM cycle.
According to the method for the invention described above embodiment, both taken into account the different DTIM cycle requirement of delay sensitive type and power sensitive type STA, also simplified the management complexity of AP for multiple DTIM.By limiting the range of choice of DTIM periodic quantity, avoided different STA to select the too wide in range DTIM periodic quantity of distribution, for the application scenarios that comprises a large amount of STA, improved AP to whole Network Management efficient.
The embodiment of the invention has also proposed to realize the AP of the data transmission method of the embodiment of the invention.Fig. 6 is the schematic configuration diagram according to the AP of the embodiment of the invention.As shown in Figure 6, AP 600 comprises:

In this case, STA still can change the DTIM periodic quantity as required.According to the embodiment of the invention, method 900 can comprise step:
950:AP receives second request message that described STA sends, and wherein said second request message carries the second type of service indication information and DTIM cycle indication message;
960:AP determines that described DTIM cycle indication information represents to change the DTIM periodic quantity;
970:AP is according to the described second type of service indication information in described second request message, selects the two DTIM periodic quantity corresponding with the indicated type of service of the described second type of service indication information from the mapping table in described DTIM cycle;
980:AP sends second response message to described STA, and wherein said second response message carries described the 2nd DTIM periodic quantity.
In this case, by second request message, just can realize the change of DTIM periodic quantity.Equally, this has brought facility when for example TSPEC message realizes the function of described second request message to existing other message of AP reporting service type by expansion STA.
The method of the above embodiment of the invention is conceived to the scheme of AP side.Data transmission method according to the embodiment of the invention is considered from the STA side, and is specific as follows described.
