Background
In an application scenario of an internet of things smart lock, a one-time or time-efficient temporary password is often required to be sent to a user. And after the user sends a request instruction to the server, the server issues a random password to the user mobile phone and the intelligent terminal. When the user operates the intelligent terminal, the terminal verifies the random password.
In the prior art, a 433M high-frequency polling or BLE manner is often adopted to construct a communication network, so as to ensure that a random password is issued to an intelligent terminal when a user operates the terminal.
Intelligent terminals based on dry battery power supply require very low standby power consumption. However, the communication method of increasing the frequency of communication increases the standby power consumption. BLE technology is limited by distance and repeater cost concerns.
The intelligent lock based on the NB-IoT technology can ensure low power consumption standby without a repeater. But NB-IoT cannot acquire the server's temporary password in real time in PSM mode. When a user operates the terminal, the terminal is awakened and interacts data with the server, at the moment, the time delay can be as long as 10 seconds, and the password verification experience is seriously influenced. If the current network is unstable, authentication may even fail.
