The device code of device 2.

In this embodiment, the device code of the second electronic device 2 to be connected may be input by the user, so that the acquiring module 500 directly receives the device code input by the user. In another embodiment, the device code corresponding to the second electronic device 2 can also be automatically read from the intermediate device 1 by the acquisition module 500.

In step S11, the reading module 501 reads the electronic device data of the second electronic device 2 to be connected from the intermediate device 1 according to the acquired device code.

The electronic device data includes a fixed IP of the NAT device 3 (ie, the second NAT device 3) corresponding to the second electronic device 2 and an nickname of the second electronic device 2.

In step S12, the active stream connection module 502 generates an online connection request for the first electronic device 2 and the second electronic device 2 according to the read electronic device data of the second electronic device 2, and stores the online request. To the intermediate device 1.

Step S13, when the second electronic device 2 receives the online request and reports the normal operation of the NAT device 3 (referred to as the second NAT device 3) connected thereto, the active stream connection module 502 transmits the second NAT device. 3 Performing a chirp conversion causes the first electronic device 2 to be connected to the second electronic device 2.

In this embodiment, the active stream connection module 502 first establishes communication with the second NAT device 3 according to the fixed IP address of the second NAT device 3 to notify the second NAT device 3 that the first electronic device 2 is required. The online nickname, and then the second NAT device 3 converts the IP address to the second electronic device 2 based on the nickname.

In step S14, the determining module 503 determines whether an error occurs in the connection between the first electronic device 2 and the second electronic device 2. When an error occurs in the first electronic device 2 and the second electronic device 2, step S15 is performed; when the first electronic device 2 is connected to the second electronic device 2 and no error occurs, step S16 is performed.

In this embodiment, when the second NAT device 3 corresponding to the second electronic device 2 cannot convert the UI to the UI corresponding to the second electronic device, or the electronic device of the second device 2 is not on the intermediate device 1 An online error occurs when the data is available.

In step S15, the reward module 504 reports the error generated by the first electronic device 2 and the second electronic device 2 to the intermediate device 1, and stores the notification of the switching mode of the first electronic device 2 to the second electronic device 2. To the intermediate device 1, then step S17 is performed.

In this embodiment, the notification of switching the online mode is the first electronic device 2 to the second electronic device, in order to notify the second electronic device 2 that it needs to switch from the passive waiting online mode to the active online mode.

In step S16, the reward module 504 successfully returns the first electronic device 2 and the second electronic device 2 to the intermediate device 1 and stores the information of the online success, and the process ends.

In step S17, the execution module 505 switches the active online mode of the first electronic device to the passive standby online mode.

In step S100, the notification module 506 notifies the server of the device code of the second electronic device 2 to which the first electronic device 2 is to be connected.

In step S101, the determining module 503 determines whether the information of the second electronic device 2 that cannot be connected by the server is received. When the information of the second electronic device cannot be connected to the server, the step S11 is performed; when the information of the second electronic device cannot be connected to the server, the step S15 is directly executed.

As shown in FIG. 4, it is a flow chart of a preferred embodiment of the passive waiting connection in the network connection control method of the present invention. In the preferred embodiment, the second electronic device 2 is in the passive standby mode as an example. The order of the steps in the flowchart may be changed according to different requirements, and some steps may be omitted.

In step S40, when the second electronic device 2 is in the passive standby online mode, the determining module 503 determines whether there is an online request of the electronic device 2 (referred to as the first electronic device 2) of another network segment. When there is an online request of the first electronic device 2, step S41 is performed; when there is no online request from the first electronic device 2, step S43 is performed.

In this embodiment, the query module 507 can query the intermediate device 1 at the first preset time interval (eg, 2S) to check whether there is an online request of the first electronic device 2. The determining module 503 determines, according to the queried information, whether there is an online request of the first electronic device 2.

In another embodiment, when the intermediate device 1 is a server, the online request of the first electronic device 2 can also be periodically sent by the server to the second electronic device 2.

In step S41, the detecting module 508 detects whether the NAT device 3 (referred to as the second NAT device 3) corresponding to the second electronic device 2 is operating normally. When the second NAT device 3 corresponding to the second electronic device 2 is in normal operation, step S42 is performed; when the second NAT device 3 corresponding to the second electronic device 2 is not operating normally, the flow ends.

In this embodiment, the detection module 508 periodically detects whether the NAT device 3 connected to each electronic device 2 is operating normally, and returns the detected condition to the intermediate device 1 by the reward module 504.

In step S42, the passive stream connection module 509 connects the first electronic device 2 and the second electronic device 2 through the second NAT device 3, and then the process ends.

In step S43, when there is no online request from the first electronic device 2, the determining module 503 determines whether the second electronic device is to be switched in the online mode. When the second electronic device needs to perform switching of the online mode, step S44 is performed; when the second electronic device does not need to perform switching of the online mode, the process ends.

In this embodiment, the query module 507 queries the intermediate device 1 at a second preset time interval (eg, 3S) to query whether there is a notification of the switching mode of the first electronic device to the second electronic device. The determining module 503 determines, according to the queried information, whether the second electronic device is to perform online mode switching.

In another embodiment, when the intermediate device 1 is a server, the notification of the switching online mode may also be sent by the server to the second electronic device.

In step S44, the execution module 505 switches the online mode of the second electronic device 2 to the active online mode to establish a connection with the first electronic device 2.
