According to some embodiments of the invention, step S400 includes, but is not limited to, the following steps:
when the first quantity is smaller than a first preset value and the service type identifier is a terminal position mobile service, determining that the communication strategy type is a first communication strategy;
and when the first quantity is smaller than a first preset value and the service type identifier is the issued control terminal service, determining the communication strategy type as a second communication strategy.
Specifically, there may be two types of service type identifiers, one is a terminal location mobile service, and the other is a control terminal service.

Specifically, referring to fig. 3, fig. 3 provides a cellular internet of things communication method based on a shared bicycle cellular internet of things communication framework, after a user unlocks, communication data are generated in application layer software of a shared bicycle internet of things terminal and are transmitted to SDK software called by the internet of things terminal, and the communication data may include the unlocking time. In the SDK software, based on a first communication strategy, when no response is given after communication data are sent to the Internet of things platform through the cell A, the communication data are cached, and then the communication data are retransmitted to the Internet of things platform after the cell A starts to periodically poll and inquire from the current moment until the cell to which the Internet of things terminal belongs is changed into the other cell B. Or when no response is generated after the communication data are sent to the platform of the internet of things through the cell A, the communication data are cached, and then the communication data are retransmitted to the application server after the first preset time. And the Internet of things platform forwards the communication data to the shared bicycle application server. And the shared bicycle application server sends the reply message of the unlocking moment received by the shared bicycle application server to the shared bicycle Internet of things terminal through the Internet of things platform.
It should be noted that different polling query periods may be set for different terminal location mobile services, for example, for a shared vehicle, the polling query period may be one query every five minutes, and for a shared vehicle, the polling query period may be one query every two minutes.
According to some specific embodiments of the present invention, when the communication policy type is the second communication policy, the step of sending the communication data between the terminal of the internet of things and the application server according to the communication policy type in step S500 includes, but is not limited to, the following steps:

Specifically, referring to fig. 4, fig. 4 provides a cellular internet of things communication method based on a shared air conditioner cellular internet of things communication framework, where a shared air conditioner application server sends communication data to an internet of things platform, where the communication data may include a control instruction for turning on an air conditioner. In the Internet of things platform, based on a second communication strategy, when no response is given after communication data are sent to the Internet of things terminal through the cell, the communication data are cached, then a second quantity of the communication data from the cell within the last 10 seconds is periodically detected, and when the second quantity is smaller than 50 or second preset time passes, the communication data are retransmitted to the shared air-conditioning Internet of things terminal. And the shared air conditioner Internet of things terminal starts the air conditioner after receiving the instruction of starting the air conditioner, and returns a message that the air conditioner is started to the shared air conditioner application server through the SDK software and the Internet of things platform.
According to some specific embodiments of the present invention, when the communication policy type is the third communication policy, the step of sending the communication data between the terminal of the internet of things and the application server according to the communication policy type in step S500 includes, but is not limited to, the following steps:
acquiring an upper limit value of communication frequency;
when the frequency of the communication data sent by the Internet of things terminal exceeds the upper limit value of the communication frequency, discarding the communication data;
acquiring a time interval of sending communication data by the terminal of the Internet of things;
and when the time interval is a preset time interval, transmitting the communication data after delaying the random number of seconds.
Specifically, referring to fig. 5, fig. 5 provides a cellular internet of things communication method based on a water meter warehouse cellular internet of things communication framework, and a water meter internet of things terminal sends communication data to an internet of things platform. In the Internet of things platform, a cell to which the Internet of things terminal belongs is determined according to communication data, and when the first number of the Internet of things terminals belonging to the same application server side in the cell is larger than 3000, a third communication strategy is started. Based on the third communication strategy, the communication frequency can be reduced according to the communication frequency upper limit value, and the traffic dispersion can be carried out in a mode of delaying the data transmission, so that the network congestion situation can be reduced. Specifically, the developer or the user may set a communication frequency upper limit value and a preset time interval in advance in the SDK software, for example, the communication frequency upper limit value may be set to transmit communication data 3 times every 12 hours, and the preset time interval may be 24 hours. And after determining that the third communication strategy is started, the Internet of things platform sends the message of starting the third communication strategy to the Internet of things terminal. And based on a third communication strategy, when communication data are sent, if the communication data are sent by the Internet of things terminal software application layer for more than 3 times every 12 hours, the communication data are discarded, and if the communication data are sent by the Internet of things terminal software application layer for no more than 3 times every 12 hours, the communication data are sent, so that the communication frequency of the Internet of things terminal is actively reduced. In addition, the SDK software can detect the time interval of the communication data sent by the terminal of the Internet of things, and if the time interval of the sending of the communication data of this time and the sending of the communication data of the last time is 24 hours, random seconds are delayed for sending the communication data of this time. By delaying the random number of seconds and then transmitting the communication data, the flow in the cell can be dispersed, and the network congestion can be reduced.
It should be noted that, in the platform of the internet of things, if it is determined that the first number of terminals of the internet of things belonging to the same application server in the cell changes to be less than 3000, the SDK software is notified to cancel the third communication policy.
