[0032] See also Figure 1 , Figure 1 The figure is a flowchart of a network switching method based on an adaptive data model provided by an embodiment of the present invention. The network switching method based on an adaptive data model in the embodiment of the present invention can be applied to an Internet of Things terminal. For example, the network switching method based on an adaptive data model can be implemented by a software program configured on the Internet of Things terminal, without the need for staff to debug and replace the SIM card on site. It is not only more timely, but also saves time and effort, thereby ensuring the uninterrupted and normal operation of the Internet of Things terminal service. Figure 1 As shown, the method includes the following steps S100-S130.

[0033] S100: Start RSRP monitoring to obtain the RSRP value of the working environment of the IoT terminal.

[0034] S110: Determine whether to start ping monitoring according to the RSRP value.

[0035] In the embodiment of the present invention, the IoT terminal starts RSRP monitoring, obtains the RSRP value of the working environment of the IoT terminal, and determines whether to start ping monitoring according to the RSRP value, wherein RSRP (Reference Signal Received Power) represents a key parameter of the received signal strength. Specifically, Figure 2 As shown, step S100 specifically includes steps S111-S113: S111, determine whether the RSRP value is lower than the preset threshold value, if the RSRP value is not lower than the preset threshold value, execute step S112, otherwise execute step S113; S112, determine not to start the ping monitoring, and return to execute the step of obtaining the RSRP value of the working environment of the IoT terminal after the preset sleep time; S113, determine to start the ping monitoring. It should be noted that in this embodiment, the preset threshold value is set according to the actual application scenario and is not specifically limited here; the preset sleep time is 30 minutes; it is understandable that in other embodiments, the preset sleep time can also be set to other times, such as 35 minutes, according to actual conditions.

[0036] S120: If the ping monitoring is started, the network disconnection switching operation and the RSRP monitoring are performed according to the monitoring result of the ping monitoring.

[0037] In an embodiment of the present invention, if the ping monitoring is started, the network disconnection switching operation and the RSRP monitoring are performed according to the monitoring result of the ping monitoring. Specifically, the preset public domain network name is pinged once every preset connection time to obtain a ping result; if the ping results for the preset number of consecutive times are all ping connection failures, the network disconnection switching operation is performed, and the ping connection times are set to 0, and after the preset sleep time, the step of obtaining the RSRP value of the working environment of the Internet of Things terminal is returned to execute; if the ping connection times are not greater than the preset times, there is one ping result that the ping connection is successful, then the step of setting the ping connection times to 0 is executed; if the ping connection times are not greater than the preset times, then the step of determining whether to perform the network disconnection switching operation is based on the recorded start time of each ping connection and the end time of receiving the ping response. More specifically, the step of determining whether to perform the network disconnection switching operation based on the recorded start time of each ping connection and the end time of receiving the ping response includes: calculating multiple interval times based on the recorded start time of each ping connection and the end time of receiving the ping response; if at least a preset number of the interval times among the multiple interval times are greater than a preset interval time threshold, determining to perform the network disconnection switching operation. It should be noted that in this embodiment, if Figure 3 As shown, the preset connection time is 30s, the preset number of times is 5 times, the ping connection number is num, the multiple time intervals are time1, time2, time3, time4 and time5, the preset number is 2, and ping monitoring is performed. There are the following three situations: Situation 1: Ping the preset public network domain name every 30s. If the ping connection fails for 5 consecutive times, perform the network disconnection switching operation, set num to 0, and re-perform RSRP monitoring after sleeping for 30 minutes; Situation 2: When num<=5, if a ping connection is successful, set num to 0, and re-perform RSRP monitoring after sleeping for 30s; Situation 3: When num<=5, each time a ping is executed, the start time of the ping connection is recorded. When a ping response is received, the end time is recorded, and then the time interval is calculated to obtain time1, time2, time3, time4 and time5. If the time interval exceeds the preset interval time threshold for more than 2 times, perform the network disconnection switching operation, set num to 0, and re-perform RSRP monitoring after sleeping for 30s.

[0038] S130. If a network switching strategy issued by the Internet of Things platform based on the adaptive data model is received, a network switching operation is performed according to the network switching strategy, wherein the network switching strategy includes first-dimensional device information and second-dimensional network switching information, the first-dimensional device information includes a first-dimensional field defined in the adaptive data model and a configured field value corresponding to the first-dimensional field, and the second-dimensional network switching information includes a second-dimensional field defined in the adaptive data model and a configured field value corresponding to the second-dimensional field.

[0039] In the embodiment of the present invention, if the IoT terminal receives a network switching strategy issued by the IoT platform based on an adaptive data model, the IoT terminal performs a network switching operation according to the network switching strategy. Figure 4 As shown, step S130 may specifically include steps S131-S133: S131, parsing the network switching strategy to obtain the first dimension device information and the second dimension network switching information; S132, performing a legitimacy check based on the first dimension device information to obtain a check result; S133, if the check result is that the check passes, performing a network switching operation based on the second dimension network switching information. It should be noted that, in this embodiment, the adaptive data model defines a first dimension field and a field value corresponding to the first dimension field, and a second dimension field and a field value corresponding to the second dimension field, wherein the first dimension field includes a device communication protocol version number, a device name, a device model, and a device IMEI, and the verification result is obtained by performing a legitimacy check based on the first dimension device information, including: parsing the first dimension device information to obtain the first dimension field; if the field value of the device communication protocol version number is consistent with the preset device communication protocol version number, the field value of the device name is consistent with the preset device name, the field value of the device model is consistent with the preset device model, and the field value of the device IMEI is consistent with the preset device IMEI, then the verification result is set to the verification pass. Understandably, if at least one of the field value of the device communication protocol version number is inconsistent with the preset device communication protocol version number, the field value of the device name is consistent with the preset device name, the field value of the device model is consistent with the preset device model, and the field value of the device IMEI is inconsistent with the preset device IMEI, then the verification result is set to the verification fail, and the network switching strategy is discarded. It is understandable that the pre-set device communication protocol version number, the pre-set device name, the pre-set device model and the pre-set device IMEI are pre-configured device basic information. Figure 5As shown, the first dimension field includes msg_version, vendor_name, model_name, and imei_data, wherein msg_version is the device communication protocol version number, vendor_name is the device name, model_name is the device model, and imei_data is the device IMEI.

[0040] Furthermore, the second dimension field includes an immediate switching policy field, a priority policy field, a weak signal switching policy field, and a last network priority policy field, and the network switching operation is performed according to the second dimension network switching information, including: parsing the second dimension network switching information to obtain the second dimension field; determining the target switching policy according to the field value of the immediate switching policy field, the field value of the priority policy field, the field value of the weak signal switching policy field, and the field value of the last network priority policy field; if the target switching policy is a real-time network switching policy, the network switching operation is performed according to the field value of the immediate switching policy field and the field value of the weak signal switching policy field; if the target switching policy is a three-network priority network switching policy, the network switching operation is performed according to the field value of the priority policy field; if the target switching policy is the last network priority network switching policy, the network switching operation is performed according to the field value of the last network priority policy field. It should be noted that in this embodiment, if Figure 5 As shown, the second dimension includes sim_switch_to, policy_operator_first, policy_signal_weak, and policy_last_operator_first, wherein sim_switch_to is the immediate switching policy field, i.e., immediately switching to the corresponding operator policy, policy_operator_first is the priority policy field, i.e., the operator priority policy, policy_signal_weak is the weak signal switching policy field, i.e., the weak signal switching operator policy, and policy_last_operator_first is the last network priority policy field, i.e., the last network operator priority policy. Understandably, the operator priority policies include "UNKNOWN", "CHINA UNICOM", "CHINA MOBILE", and "CHINA TELECOM", "CHINA UNICOM" is China Unicom, "CHINA MOBILE" is China Mobile, and "CHINA TELECOM" is China Telecom. It should also be noted that in this embodiment, if Figure 6As shown, the IoT terminal is configured with an application and a communication module. The IoT platform sends the network switching strategy to the application. The application parses the network switching strategy to obtain the first dimension device information and the second dimension device information. After that, the first dimension device information is parsed to obtain the first dimension field. The legitimacy of the field value of the first dimension field is checked. The second dimension field is obtained by parsing the second dimension network switching information. That is, according to the value of sim_switch_to or policy_operator_first or policy_last_operator_first or policy_signal_weak, different network switching execution strategies are enabled to determine the target switching strategy. Specifically, if the target switching strategy is the real-time network switching strategy, the application sends a real-time network switching instruction to the communication module according to the field value of sim_switch_to, and after receiving the response message sent back by the communication module, saves the network with weaker signal in the field value of policy_signal_weak; if the target switching strategy is the three-network priority network switching strategy, the application sets the three-network priority network operator according to the field value of policy_operator_first, and sends a restart module instruction to the communication module. After receiving the response message sent back by the communication module, the three-network priority network operator is obtained, and the application sends a network switching instruction according to the obtained network operator; if the target switching strategy is the last network priority network switching strategy, the application saves the current successful network operator according to the field value of policy_last_operator_first, sets the last network status, sends a restart module instruction to the communication module, obtains the last network status after receiving the response message sent back by the communication module, obtains the operator used for the last network, and sends a network switching instruction according to the obtained network operator.

[0041] like Figure 7 As shown, in this embodiment, the user customizes an adaptive data model in the Internet of Things platform. Based on the adaptive data model, the Internet of Things platform sends a network switching strategy to the Internet of Things terminal. After receiving the network switching strategy, the Internet of Things terminal sends a response message back to the Internet of Things platform and sets the network switching strategy flag. The Internet of Things terminal device restarts, reads the network switching strategy flag, and executes the network switching operation; and the Internet of Things terminal is pre-set with a device that powers on to start the network disconnection switching operation, which is achieved by periodically monitoring the network status of the Internet of Things terminal and executing the network disconnection switching operation when the network is unavailable.

[0042] In summary, based on the network switching strategy issued by the customized adaptive data model of the IoT platform and the network monitoring and disconnection switching operations preset by the IoT terminal, when the IoT terminal network is unavailable, the normal switching of the IoT terminal cellular network can be completed by restarting the device. It has strong timeliness and saves labor costs. It greatly ensures the uninterrupted and normal operation of the IoT terminal equipment business without changing the original business processing.
