In another embodiment of the present application, according to the wifi direct connection message, establishing a direct connection link with the opposite wifi device supporting wifi direct connection may be implemented through the following steps S '1021 to S' 1023.
Step S'1021: a first group is established.
As a group management terminal, namely a group owner, wiFi direct connection initiating equipment can automatically scan WiFi equipment in the signal range when being started, if original WiFi equipment in a certain group is scanned, connection is automatically initiated to the scanned original WiFi equipment, and a first group is formed. If the user does not scan, prompting whether the user uses other groups stored currently, and if so, taking the other groups stored currently as the first group.
Step S'1022: and allowing at least one WiFi direct-connected device to join the first group according to the WiFi direct-connected message.
Step S'1023: information about the first group and device information of all wifi devices supporting wifi direct connection in the first group are stored.

In order to reduce manual input device information of a user or manually select a device end, complex operation of establishing connection between wifi direct-connection initiating equipment and a target wifi device end is avoided, complicated device information input by the user is avoided, and the method further comprises the following steps: detecting whether a wifi direct connection initiating device locally stores device information of a history wifi device supporting wifi direct connection or not, and directly connecting the history wifi device with the wifi direct connection initiating device to record information; if the Wifi direct connection initiating device locally stores the device information of the history Wifi device supporting the Wifi direct connection and the direct connection record information of the history Wifi device and the Wifi direct connection initiating device, starting a Wifi device direct connection scanning function of the Wifi direct connection initiating device so as to scan the Wifi device supporting the Wifi direct connection in a preset range; according to the equipment information of the historical wifi equipment, a direct-connection link between the wifi direct-connection initiating equipment and the wifi equipment existing in the wifi direct-connection initiating equipment is established. In the above embodiment, after the target device which is directly connected with the wifi direct connection initiation device is detected, the target device is stored as the historical wifi device which supports the wifi direct connection.
In order to reduce the energy consumption, in the embodiment of the present application, the method further includes: determining a current wifi history device which establishes a direct link with a wifi direct-connection initiating device currently; acquiring and analyzing interaction information of the wifi direct-connection initiating device and each current historical wifi device within a preset time period in the past, and determining interaction heat of the wifi direct-connection initiating device and each current historical wifi device; and closing a direct link of the current historical wifi equipment with the wifi direct-connection initiating equipment, the interaction heat of which is smaller than a first threshold value, and/or closing a direct link of the current historical wifi equipment with the wifi direct-connection initiating equipment, the interaction heat of which is smaller than a second threshold value, wherein the second threshold value is larger than the first threshold value. In the above embodiment, the interaction information mainly includes the frequency, duration, transmission data amount, and the like of the data interaction between the wifi direct-connection initiation device and different current historical wifi devices, and the frequency, duration, transmission data amount, and the like of the data interaction are positively related to the interaction heat, that is, the greater the data interaction frequency between the wifi direct-connection initiation device and one current historical wifi device is, the higher the interaction heat between the wifi direct-connection initiation device and the current historical wifi device is; similarly, the larger the duration of data interaction between the wifi direct-connection initiating device and the current historical wifi device is, the higher the interaction heat is, the larger the transmission data volume is, and the higher the interaction heat is. The frequency, duration and weight of the positive correlation of the transmission data quantity and the interaction heat of the data interaction can be set automatically according to the reference scene or user requirements of the wifi direct-connection initiation device and the current historical wifi device. When wifi directly links to launch equipment and each current history wifi equipment's interactive heat is less than first threshold value, indicate that wifi directly links to launch equipment and the wifi of current history wifi equipment are mutual very little, wifi directly links between wifi directly links to launch equipment and the current history wifi equipment availability ratio is very low, it will consume wifi directly to launch equipment and the excessive electric quantity of current history wifi equipment to last opening, consequently, close the wifi directly links of the current history wifi equipment that interactive heat is less than first threshold value and wifi directly links to launch equipment, save the electric quantity of wifi directly links to launch equipment and current history wifi equipment. When the interaction heat of the wifi direct-connection initiating device and each current historical wifi device is smaller than the second threshold and larger than or equal to the first threshold, the interaction frequency of the wifi direct-connection initiating device and each current historical wifi device is moderate, the use ratio of the wifi direct-connection link between the wifi direct-connection initiating device and each current historical wifi device is low, more electric quantity of the wifi direct-connection initiating device and each current historical wifi device is consumed when the wifi direct-connection initiating device is continuously started, therefore, the dormancy interaction heat is smaller than the wifi direct-connection link between the wifi direct-connection initiating device and each current historical wifi device, the second threshold is larger than or equal to the first threshold, and the dormant wifi direct-connection link is awakened by the interaction requirement.
Step S103: through the direct link with the opposite terminal wifi equipment that supports wifi and directly link, to the opposite terminal wifi equipment that supports wifi and directly link send the instruction to make the opposite terminal wifi equipment that supports wifi and directly link carry out the instruction.
In the embodiment of the application, the instruction sent to the opposite-end wifi device supporting wifi direct connection includes instruction to play music and/or alert tones, connect to a home network and other specified network and other actions of the opposite-end wifi device supporting wifi direct connection, and these instructions may be packaged in a vendor specific attribute (Vendor Specific Attribute, VSA) package conforming to the wifi direct connection protocol. And after the opposite-end wifi equipment supporting wifi direct connection receives the VSA packet, analyzing an instruction in the VSA packet according to a wifi direct connection protocol and executing the instruction.
According to the communication method of the wifi equipment illustrated in the attached drawing 1, after the wifi direct connection message is interacted with the opposite-end wifi equipment, if the opposite-end wifi equipment supports wifi direct connection, a direct connection link of the opposite-end wifi equipment which supports wifi direct connection is established according to the wifi direct connection message, and then an instruction is sent to the opposite-end wifi equipment which supports wifi direct connection through the direct connection link, so that the opposite-end wifi equipment which supports wifi direct connection executes the instruction, therefore, the technical scheme of the application enables direct communication among a plurality of the equipment which supports wifi direct connection, dependence on routing equipment or AP is avoided, and the communication method is particularly suitable for a scene without a network.
