Description
Technical field
The present invention relates to electronic technology field, relate in particular to a kind of electronic equipment and control the method for described state of electronic equipment.
Background technology
Along with people are more and more with the demand of sharing to linking up, in the prior art, all be provided with wireless communication module in a lot of electronic equipments, as: the WLAN chip, the user can realize and being connected of network by wireless communication module, and then one side can obtain data by network, as: photo, music, multimedia file etc.; On the other hand can be by network with the transfer of data on the electronic equipment or be shared with other equipment, as: with the music in the electronic equipment, the good friend of oneself is given in photo or daily record etc. by Internet Transmission.
Today, a lot of electronic equipments all are that mobile device all utilizes battery to power, so, how effectively reducing power consumption, it is very important that the service time of battery of electronic equipment is prolonged as far as possible for the user.
So, for the electronic equipment that comprises wireless communication module, particularly mobile electronic device, how when realizing radio communication function, reduce power consumption, be that industry is in the problem of research always.
In the prior art, mobile device is that power saving can periodically be revived and dormancy, the data of coming in order to guarantee not lose other equipment between rest period, (Access Point: access point) mobile device for dormancy provides the buffer memory service to the AP by lasting Power supply is arranged usually.
For mobile device, two kinds of power ratings are arranged usually, i.e. Awake (wake states) and Sleep (resting state).For electrical energy saving, reduce power consumption, mobile device generally can remain on the Sleep state as far as possible, only is transformed into when being necessary the Awake state.When the Sleep state, mobile device can't receive data, and the data that therefore are sent to mobile device can at AP place buffer memory, namely temporarily be stored in the memory cell among the AP.AP can comprise a data dial gauge TIM in the Beacon of periodic broadcast frame (TIM:Traffic Indication Map: the data dial gauge), TIM indicates current all data at the mobile device of AP place buffer memory.
In order to obtain from AP the data of mobile device, the mobile device that is in the Sleep state must periodically wake up, carries out the Awake state, then receives the Beacon frame from AP, is buffered to have determined whether one's own data.If TIM indication mobile device has data buffer storage, just mobile device is sent out a PS-Poll frame to AP.AP will send the packet that belongs to this mobile device to mobile device after receiving the PS-Poll frame.
From foregoing description as can be known, by above-mentioned mechanism, can save energy, reduce power consumption, but also to pay the cost of network transmission performance simultaneously, the most serious is prolongs the response time of application program, that is: at mobile device during at the Sleep state, owing to can not receive Beacon frame from AP, and only just can receive Beacon frame from AP at the Awake state, so, for mobile device, can not obtain to belong in time the data of this mobile device from AP.
In order to solve the problems of the prior art, following solution has been proposed again in the prior art, that is: mobile device sends a trigger frame to obtain the packet that is buffered in AP to access point, in concrete the application, trigger frame can be that the triggering of mobile device configuration enables the affiliated QoS data of AC (trigger-enabled Access Category), also can be QoS Null frame.
In this scheme, mobile device can use any upstream data bag to be sent as trigger frame, therefore, this scheme is fit to the two-way communication application scenarios of flow symmetry, for example VoIP very much, because under the application scenarios of flow symmetry, upstream data is always arranged, so, can not take Internet resources with upstream data as trigger frame, and in time, can guarantee preferably that mobile device can obtain to belong to the data of this mobile device in real time from AP.
The inventor finds that there is one of following problem at least in above-mentioned prior art in realizing process of the present invention;
One, when the application scenarios of mobile device when downlink traffic is large for uplink traffic is little, this moment, uplink traffic will be not enough, and then cause mobile device to lack can be used as the upstream data bag of trigger frame, so exist can not be in time from the technical problem of the data of this mobile device of AP acquisition.
Two, even for solving because lacking the upstream data bag that can be used as trigger frame, can produce QoS Null frame by mobile device and send as trigger frame.But there is not good method to determine a rational QoS Null frame transmission rate in the prior art, so, when transmission rate is excessive, then can cause the power consumption of mobile device excessive; When transmission rate is too small, then can cause mobile device can not in time obtain to belong to the data of this mobile device from AP.
