Describe in detail with reference to the accompanying drawings according to each embodiment of the present invention.Here it is to be noted that it in the accompanying drawings, identical Reference numeral is given there is identical or similar structures and function part substantially, and the repeated description of will omit about them.
As shown in Figure 1, the schematic diagram of the direct-connected process of establishing of WiFi in prior art is shown.According to the direct-connected agreement of existing WiFi, be altogether provided with 11 communication channels direct-connected for WiFi, wherein first communication channel ch1, the 6th communication channel ch6 and the 11 communication channel ch11 are completely not overlapping each other; Wherein the first to the five communication channel ch1-ch5 may exist each other and partly overlaps, the second to the six communication channel ch2-ch6 may exist each other and partly overlaps, six to the ten communication channel ch6-ch10 may exist each other and partly overlaps, and the seven to the ten one communication channel ch7-ch11 may exist each other and partly overlaps.
When P2P equipment 1 opens the direct-connected function of WiFi, first it scan all communication channels, start to intercept the probe requests thereby whether having other P2P equipment to send after the scanning completing all communication channels, time of intercept interval can be natural number for N number of 100TU(N, 1TU is approximately 1ms), when not listening to the probe requests thereby that other P2P equipment sends, P2P equipment 1 enters interval search time, in search time interval, P2P equipment 1 is successively at completely nonoverlapping three communication channel (first communication channel ch1 each other, second communication channel ch6 and the 11 communication channel ch11) on send probe request message, and if there is the probe response from other P2P equipment, then P2P equipment 1 receives probe response message in respective communication channel.
As shown in Figure 1, after P2P equipment 1 opens the direct-connected function of WiFi, P2P equipment 2 also opens the direct-connected function of WiFi, and the time of intercept interval of P2P equipment 1 can be set to 100TU, and the time of intercept interval of P2P equipment 2 can be set to such as 3 100TU.In the case, after P2P equipment 1 and P2P equipment 2 all open the direct-connected function of WiFi, before P2P equipment 1 and P2P equipment 2 find the other side each other, long period may be needed, such as, the time of intercept interval of channel scan time t1, P2P equipment 1 of P2P equipment 2 can be comprised, time that P2P equipment 1 is searched on first communication channel ch1, P2P equipment 1 sends probe request message and receive the time (can be approximately equal to the time that P2P equipment 1 is searched at the 6th communication channel ch6) of probe response message from P2P equipment 2 on the 6th communication channel ch6.
