[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 a local communication link quality indicator 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 according to the obtained local communication link quality indicators, capability values ​​and service quality parameters required by the Internet of Things gateway.

[0074] S30: After processing the 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 Internet of Things 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] It can be compatible with and allocate multiple frequency bands at the same time. The following scheme only describes the process when allocating one frequency band. This method designs a method for avoiding interference of multiple protocols used in the home. The Internet gateway is also a multi-mode IoT gateway that can support the switching and use of multiple IoT protocols. The IoT gateway is a single-mode gateway that only supports one IoT protocol. After the Internet gateway is powered on, it scans the 2.4GHz frequency band to obtain the global communication link quality index. The IoT gateway performs a channel scan within the protocol before accessing the Internet gateway, and obtains the local communication link quality index after processing. The IoT gateway reports the communication link quality index, capability value and required service quality parameters when accessing the Internet gateway. The Internet gateway allocates the frequency domain, reconnection key and agrees on the next communication time and communication duration to the IoT gateway based on the global communication link quality index, the local communication link quality index and the capability value and service quality parameters reported by the IoT gateway. After completing the above process, the Internet gateway disconnects from the IoT gateway and switches to other protocol modes to perform other tasks. The IoT gateway receives the information uploaded by the connected IoT device for processing and cache. After the agreed time is reached, the Internet gateway switches to the corresponding Internet of Things protocol mode and communicates with the agreed Internet of Things gateway to receive the data cached by the Internet of Things 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 the Internet gateway is powered on, it will perform a scan operation to obtain information such as signal strength (RSSI), channel occupancy, interference source identification, and adjacent channel interference (ACI / CCI). In the subsequent continuous operation process, it will continue to collect information such as bit error rate, delay, and packet loss rate that require communication to obtain. Then, a table describing the global communication link quality is obtained.

[0083] After power-on, if the Internet gateway has no connected device, the protocol mode will be switched. For example, in this embodiment, the protocol mode is switched to the Zigbee protocol mode, the agreed default channel 11 is monitored, and the Zigbee broadcast message is continuously monitored for 500ms.

[0084] When a message containing private fields is detected from a ZigBee gateway, the authentication process begins. After authentication, the local communication link quality description table, capability value, and required transmission rate reported by the ZigBee gateway are received. The capability value mainly includes supported channels, security, and data rate. The required transmission rate is calculated by the ZigBee gateway. The required transmission rate is usually determined by the amount of information to be uploaded and the bandwidth required for internal communication in the network.

[0085] After algorithm calculation, the Internet gateway allocates a frequency band that can meet the needs of the ZigBee smart home system from the global communication link quality description table to the ZigBee gateway, such as the frequency band from 2405MHz to 2415MHz for the system to use. The Internet gateway allocates a 50ms time slot after 200s to the gateway for information transmission based on the upload data volume required by the ZigBee gateway, such as 5kb, and the minimum interval time, such as 30 minutes.

[0086] Then within these 200 seconds, the Internet gateway will continue to switch to other protocol modes, such as the default channel 3 of the WiFi protocol in this embodiment to receive broadcast packets from the mesh router master device. After confirming that the broadcast packet contains private fields, the authentication process is entered. After the authentication is passed, the Internet gateway allocates the frequency band of 2432MHz to 2462MHz to the mesh router for free use according to the similar process as above. It is agreed that information transmission can be carried out within 180 seconds after 0.5s. The mesh router device must cache information during the communication interval.

[0087] After the above steps, the subnets within the home can be divided according to the frequency domain to avoid mutual interference, which can effectively reduce power consumption for IoT devices, because the frequency bands within the controllable scene are planned, which can reduce the communication link quality detection overhead and ensure the communication quality and reduce the number of retransmissions. Moreover, wireless communication is used, which is convenient for layout and use in the home environment.
