[0070] In a specific embodiment, Figure 3 As shown, S10: the Internet gateway performs channel scanning to obtain a global communication link quality indicator in the 2.4 GHz frequency band.

[0071] S11: The IoT gateway performs channel scanning to obtain local communication link quality indicators within the IoT gateway protocol.

[0072] S20: The IoT gateway reports the local communication link quality indicators, capability values, and service quality parameters obtained when accessing the Internet gateway.

[0073] S21: After the Internet gateway is connected to the Internet of Things gateway, the Internet gateway allocates a frequency band usage range and a communication time slot to the Internet of Things gateway based on the obtained local communication link quality indicators, capability values, and service quality parameters required by the Internet of Things gateway.

[0074] S30: After processing this access request, the Internet gateway device enters the waiting state or continues to process the access or information upload of other IoT gateways.

[0075] S31: The IoT gateway caches the information uploaded by the connected IoT device in the cache area.

[0076] S40: When the agreed communication time is about to arrive, the Internet gateway switches to the protocol mode corresponding to the Internet of Things gateway.

[0077] S41: The IoT gateway reconnects to the Internet gateway and uploads the cached information.

[0078] S50: The Internet gateway reallocates the next communication time and time slot to the IoT gateway.

[0079] S51: The IoT gateway disconnects and enters a loop, and the Internet gateway switches to other protocol modes to perform other tasks.

[0080] Multiple frequency bands can be allocated simultaneously. The following scheme only describes the process for allocating a single frequency band. This method designs a multi-protocol interference avoidance method for home use. The Internet gateway is also a multi-mode IoT gateway, supporting the switching and use of multiple IoT protocols. The IoT gateway is a single-mode gateway, supporting only one IoT protocol. After powering on, the Internet gateway scans the 2.4 GHz frequency band to obtain global communication link quality indicators. Before connecting to the Internet gateway, the IoT gateway performs a channel scan within the protocol and obtains local communication link quality indicators after processing. Upon connecting to the Internet gateway, the IoT gateway reports the communication link quality indicators, capability values, and required quality of service parameters. Based on the global communication link quality indicators, local communication link quality indicators, and the capability values ​​and quality of service parameters reported by the IoT gateway, the Internet gateway assigns a frequency domain, a reconnection key, and agrees on the next communication time and duration. After completing the above process, the Internet gateway disconnects from the IoT gateway and switches to another protocol mode to perform other tasks. The IoT gateway receives information uploaded by connected IoT devices, processes it, and caches it. After the agreed time is reached, the Internet gateway switches to the corresponding IoT protocol mode and communicates with the agreed IoT gateway to receive the data cached by the IoT gateway.

[0081] In a specific embodiment, Figure 4 As shown, this embodiment includes a Zigbee smart home system, a mesh router network, and an Internet gateway.

[0082] After powering on, the internet gateway performs a scan to obtain information such as signal strength (RSSI), channel occupancy, interference source identification, and adjacent channel interference (ACI / CCI). During subsequent operation, it also collects information that requires communication, such as bit error rate, latency, and packet loss rate. This provides a table describing the global communication link quality.

[0083] After power-on, if the Internet gateway has no connected devices, it will switch the protocol mode. For example, in this embodiment, it will first switch to the Zigbee protocol mode, monitor the agreed default channel 11, and continuously monitor the Zigbee broadcast message for 500ms.

[0084] Upon detecting a message containing private fields from a ZigBee gateway, the authentication process begins. After authentication, the ZigBee gateway reports a table describing the local communication link quality, capability values, and required transmission rate. Capabilities primarily include supported channels, security, and data rates. The required transmission rate is calculated by the ZigBee gateway. The required transmission rate is typically determined by the amount of information to be uploaded and the bandwidth required for communication within the network.

[0085] After performing an algorithmic calculation, the internet gateway allocates a frequency band suitable for the ZigBee smart home system, such as the 2405MHz to 2415MHz band, from a global communication link quality description table. Based on the upload data volume (e.g., 5 KB) and minimum interval (e.g., 30 minutes) reported by the ZigBee gateway, the internet gateway assigns the gateway a 50ms time slot for information transmission after 200 seconds.

[0086] During this 200-second period, the internet gateway will switch to other protocol modes, such as the default WiFi protocol channel 3 in this example, to receive broadcast packets from the mesh router master. After confirming that the broadcast packet contains private fields, the authentication process begins. Following a similar process as described above, the internet gateway allocates the 2432MHz to 2462MHz frequency band to the mesh router for free use. Information transmission is permitted for up to 180 seconds after the 0.5-second interval. The mesh router, however, must buffer information during the communication interval.

[0087] After completing the above steps, subnets within the home can be divided by frequency domain to avoid mutual interference. This can effectively reduce power consumption for IoT devices, especially because the frequency bands within controllable scenarios are planned, which can reduce the communication link quality detection overhead, ensure communication quality, and reduce retransmissions. Furthermore, all wireless communication is used, making it easy to deploy and use in a home environment.
