Communication terminal of the present invention when 100 initialization device discovery messages frames or service discovery messages frame, prestored the initialization period T of a described device discovery messages frame or service discovery messages frame of communication terminal 100, described initialization period T is fixed.
When the time point of the initialization period T of described device discovery messages frame or service discovery messages frame arrives, according to CCA mechanism, before sending message frame, whether communication terminal 100 can detect current channel busy, generally be detection signal strength, if signal strength signal intensity surpasses certain threshold value, just determine channel busy, according to random back mechanism, communication terminal 100 will produce the random back time window and send message frame so.Described random back time window is actual to be a transmission cycle maximum of T 1.From described transmission cycle maximum of T 1, produce a current transmission cycle A more at random.
When the time point of the current transmission cycle of described device discovery messages frame or service discovery messages frame A arrives, before sending message, whether communication terminal 100 can detect channel busy, if not busy described device discovery messages frame or the service discovery messages frame of then sending; If busy then according to random back mechanism, communication terminal 100 will produce random back time window (sending cycle maximum of T 2) and send the discovery message frame, produces a current transmission cycle B again from described transmission cycle maximum of T 2 at random.
Be understood that easily subsequent communications terminal 100 can continue to judge whether the time point of current transmission cycle B arrives, if then whether communication terminal 100 meeting detection channels are busy; If not busy described device discovery messages frame or the service discovery messages frame of then sending; If busy is then according to random back mechanism, produces random back time window (sending cycle maximum of T 3) and send message frame.Produce a current transmission cycle C at random again in sending cycle maximum of T 3, so circulation is gone down, and is sent out away until described device discovery messages frame or service discovery messages frame.Certainly, also can limit the high reps of random back here, inferior as 3.
In the present embodiment, communication terminal 100 is divided into several grades according to the produce number of times of judging channel busy with transmission cycle of device discovery messages frame or service discovery messages frame, for example: judge that when communication terminal 100 number of times of channel busy is 3 times, the transmission cycle maximum of device discovery messages frame or service discovery messages frame is T1 so; Judge that when communication terminal 100 number of times of channel busy is 6 times, the transmission cycle maximum of device discovery messages frame or service discovery messages frame is T2 so, and it is inequality with transmission cycle maximum of T 2 to send cycle maximum of T 1, and in general the value of T2 is greater than the value of T1.
Generating the current transmission cycle from described transmission cycle maximum at random can adopt two kinds of preferred process methods:
A) communication terminal 100 can be from selecting a time value as the current transmission cycle at random between initialization period T and the present transmission period maximum, and the time of this current transmission period ratio initialization period T is long;
After communication terminal 100 was finished the transmission of described device discovery messages frame or service discovery messages frame, the device discovery messages frame of next round or the transmission cycle of service discovery messages frame were set to the initialization period T, and so far whole process is finished.
In sum, when the present invention arrived in the transmission cycle of message frame, judge whether current channel is busy, as if described channel busy, then adjust the transmission cycle of described message frame, if described channel is not busy, then send described message frame.Whereby, the present invention can realize dynamically sending cycle mechanism, and namely communication terminal can dynamically be adjusted the transmission cycle of message frame according to the busy extent of current channel, thereby improves the transmitting efficiency of message frame.Preferably, described message frame is device discovery messages frame or service discovery messages frame, the present invention is by the discovery mechanism of cycle dynamics, has improved the efficient of service discovery in the wlan network or device discovery, makes communication terminal to find mutually quickly.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
