Communication switching method, device, and Internet of Things communication module

Abstract

Embodiments of the present invention provide a communication switching method, device, and IoT communication module. The method includes: connecting to the network through a physical SIM card connected to the communication module of the Internet of Things; monitoring the network status of the physical SIM card in real time according to the monitoring strategy; judging whether the network status of the physical SIM card satisfies the trigger condition for switching networks; if the physical SIM If the network status of the card satisfies the triggering conditions for switching networks, the network is connected through the pre-installed soft SIM card in the IoT communication module. By presetting the soft SIM card in the IoT communication module, enabling the soft SIM to provide a backup network when needed, ensuring the connection with the cellular mobile communication network for timely and effective communication, improving the reliability of communication, and without operating Maintenance personnel are required to perform on-site maintenance, reducing maintenance costs.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a communication switching method, device and Internet of Things communication module. Background technique [0002] With the rapid development of Internet of Things technology, it has played an important role in many fields such as smart home, remote smart meter reading, wireless mobile sales terminals and location tracking. A large number of IoT devices do not have human-computer interaction interfaces, and do not have wireless networking capabilities such as WIFI and Bluetooth. They need to rely on cellular mobile communication networks provided by operators to realize information interaction. At present, the mainstream IoT communication modules on the market only support one physical Subscriber Identification Module (SIM) card, and IoT devices rely on the cellular mobile communication network provided by the single operator to which the physical SIM card...

AI Technical Summary

Problems solved by technology

[0003] Due to the complex application scenarios of IoT devices, IoT devices that rely on a single operator to which the physical SIM card belongs to communicate, often due to various reasons, such as the area where the IoT device is deployed is not covered by the network of the operator to which the physical SIM card belongs, the physical SIM Card failure, operator network failure, etc., resulting in IoT devices not being able to connect to the cellular mobile communication network

As a result, it is impossible to communicate in a timely manner, which reduces the reliability of IoT device communication, and requires operation and maintenance personnel to go to the deployment area of ​​IoT devices for on-site maintenance, resulting in high maintenance costs.
