Network switching method and network switching system

Abstract

The invention provides a network switching method and a network switching system. The method includes the steps that an internet of things device builds an emergency call channel with an emergency call center through a second network when a state of a first network covering the internet of things device is detected to be unavailable; the emergency call center sends an identity label of the internet of things device to an internet of things management platform; the internet of things management platform selects a target network for the internet of things device according to the identity label of the internet of things device, and activates the target network; the emergency call center sends a network switching indicating message to the internet of things device through the emergency call channel; and the internet of things device switches a network to the target network according to the network switching indicating message. According to the network switching method and the network switching system, the internet of things device communicates with the internet of things management platform through the emergency call center when a current operator network breaks down, the current operator network is switched into other available networks through the internet of things device, therefore service borne by the internet of things device can be developed continuously, and service processing capacity of the internet of things device is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a network switching method and system. Background technique [0002] With the popularization of IoT technology, sensors and communication modules are embedded in more and more traditional commodities, such as automobiles, smart meters, consumer electronics and monitoring equipment, etc. These commodities embedded with sensors and communication modules are called the Internet of Things equipment. Generally, IoT devices collect information from the physical world through sensors, and send the information collected by sensors to the IoT management platform through communication modules. The Internet of Things management platform mainly provides general basic services such as information processing and computing for Internet of Things devices, and provides resource call interfaces for Internet of Things devices, so as to realize various applications of Internet of Things in many fields. ...

AI Technical Summary

Problems solved by technology

[0004] In practical applications, if the IoT device undertakes important services, such as security monitoring, it needs to be connected to the operator's network in real time. During this period of time before the connection returns to normal, the business will not be able to carry out normal business, which seriously affects the business processing capability of IoT devices.
