The application also provides an application scene, and the application scene applies the communication control method. Specifically, the creation flow of the private cluster is as shown in fig. 3, and the communication control method is applied in the application scenario as follows: the two pNAN devices D1 and D2 realize mutual discovery through the beacon frame or the cluster identifier carrying the private mode information, the pNAN devices refer to devices supporting the private mode, and when the devices D1 and D2 discover each other, namely when the server detects that the beacon frames of the devices D1 and D2 contain the preset private mode information, the master device appoints a message to the management terminal. The user brakes one of the devices through the management terminal as a master device, for example, designates D1 as the master device, the server receives a master device identifier fed back by the management terminal, acquires the key information, and the control device D1 creates the private cluster according to the key information. The device D2 may join the private cluster by inputting a key or by scanning a two-dimensional code generated by the device D1 according to the key information. Device D2 may also join the private cluster by receiving the group offer message pushed by D1, activating the group offer message. The device D1 sends a management frame encrypted by using the key K, the management frame can be decrypted only by the device D2 with the key K, in the created private cluster, the device D1 sends a discovery beacon and a synchronization beacon carrying private mode information, the synchronization information is encrypted, and the device D2 receives the beacon carrying the private mode information.
The application also provides an application scenario, and the application scenario applies the communication control method. Specifically, the procedure of joining the private cluster is shown in fig. 4, and the communication control method is applied in the application scenario as follows: and D1 receives the beacon frame which is sent by the pNAN device D3 and carries the private mode information and is added with the cluster identifier or D3 receives the beacon frame which is sent by D1 and carries the private mode information and is created with the cluster identifier, and the D3 is judged to enter the signal coverage range of the device D1. When the D3 enters a signal coverage range of the device D1 and the added cluster identifier is different from the created cluster identifier, the server receives a group entering message initiated by the D3, wherein the group entering message carries the key information to be verified; and when the key information to be verified is consistent with the key information of the D1, the control device D3 is added into the private cluster created by the D1. Or when detecting that the D3 enters the signal coverage of the device D1, the server controls the main device to push a group invitation message to the device D3, wherein the group invitation message is obtained by the device D1 according to the key information; when detecting that device D3 activates the group offer message, controlling device D3 to join the privacy cluster created by D1.
The communication control method can realize that one cluster A comprising a plurality of devices and another cluster B comprising a plurality of devices are independent from each other, namely, the information of each independent cluster cannot be accessed, the cluster is shown in fig. 5, and one device can belong to both the cluster A and the cluster B so as to ensure the communication safety between the cluster devices. The communication control method can be applied to a conference perception scene, and all devices in a conference room, such as televisions, projectors, mobile devices and the like, can perceive the existence of each other based on a neighbor perception network. When a user wishes to project a screen of a mobile phone through a television/projector or to transfer data between devices, only users who are in the same meeting room and join a particular cluster can access the screen or the transferred data, and thus there is no need to worry about privacy or security issues. The communication control method can also be applied to order perception scenes, taking a coffee shop as an example, by creating a private cluster in the coffee shop, a user can receive order prompting information on a mobile phone, and after a merchant receives an order, the user can be separated from the private cluster and switched to a NAN public mode. The communication control method can also be applied to an attendance perception scene, the user can complete attendance by scanning the two-dimensional code generated by the NAN main equipment through the user terminal, and in addition, the NAN main equipment can serve as a router with NAN function for equipment verification. The communication control method can also be applied to a learning group perception scene, for example, students who study in a library can establish an information sharing private cluster to realize information sharing such as notes.
