The response message may include the following fields: the total length of the message, the type of the message, the length of the instruction, the content of the instruction, and the checksum (the checksum field is an optional field). Thereby, the user equipment can know more accurately whether to allow access to the network.

In an embodiment, the network connection information may include a network connection password. In addition, the network connection information may further include a Service Set Identifier (SSID). In this embodiment, when the gateway device establishes a WPS connection with the user equipment, the gateway device may notify the user equipment of the service set identifier SSID.

In one embodiment, the network connection information may include a network connection password, and in addition, the network connection information may further include an SSID.

The inventive concept will be described in detail below with reference to embodiments of the invention.

In the related art, the smart terminal device (corresponding to the user equipment) accesses the smart home gateway (corresponding to the gateway device) for the first time, and is generally implemented by the following method.

Press and hold the button on the smart terminal device to enter the ready to access network mode and start capturing packets. The user operates through the APP on the mobile phone to prepare to add the smart terminal device, and controls the smart home gateway to broadcast or multicast the WiFi connection information including the SSID and/or the WiFi password. The smart terminal device grabs the data packet containing the WiFi password and extracts the WiFi connection information. The smart terminal device uses the extracted WiFi connection information to connect with the smart home gateway. If the connection is successful, the smart terminal device accesses the network.

There are two main problems in the above solution. First, the WiFi password may be obtained by a third-party device through broadcast or multicast, resulting in password leakage. Second, when the smart terminal device performs packet capture, it is uncertain because of the router (ie, intelligence). The WiFi working channel of the home gateway may fail to capture the packet and fail to obtain the WiFi password, resulting in a high probability of failure to access the network.

At step 706, the smart home terminal device sends a network access request message. The network access request message may include a protocol identifier, a total length, a message type, an instruction length, an instruction content, and a checksum field, as shown in Table 1. The checksum field is used for program verification message integrity and is a non-essential field (ie, an optional field).

Table 1

At step 708, the smart home gateway device receives the network access request message and determines whether the smart home terminal device is allowed to access the network. If the smart home terminal device is allowed to access the network, a response message allowing access to the network is returned. The response message allowed to access the network may include a protocol indication, a total length, a message type, an instruction length, an instruction content, and a checksum field, as shown in Table 2. Similarly, the checksum field is used for program verification message integrity and is a non-essential field.

If the smart home terminal device is not allowed to access the network, a response message rejecting the access to the network is returned. The response message rejecting the access network may include a protocol identifier, a total length, a message type, an instruction length, an instruction content, and a checksum field, as shown in Table 3. Similarly, the checksum field is used for program verification message integrity and is a non-essential field.

As shown in FIG. 10, the flowchart of this embodiment may include steps 1002 through 1012.

Steps 1002 through 1006 are substantially the same as steps 902 through 906 described above.

At step 1008, if the user does not allow the smart home terminal device to access the network, the mobile phone APP sends a rejection of the smart home terminal device access network response message to the smart home gateway device.

At step 1010, the smart home gateway device returns to the smart home terminal device that the network response message is not allowed to be accessed.

At step 1012, the smart home terminal device disconnects the WPS connection from the smart home gateway device.
