Abstract

The invention provides an operator network switching method and device. The operator network switching method comprises the steps that: an intelligent card receives a network switching request from an IOT ((Internal of Things) device, wherein the network switching request carries an available network information list comprising network information of at least one currently available network; and the intelligent card determines an available network based on the available network information list, and activates the user signing information of an operator corresponding to the available network so as to enable the IOT device to access the available network based on the user signing information, wherein user signing information corresponding to at least two operators are stored in the intelligent card. According to the operator network switching method and device provided by the invention, automatic switching of an IOT terminal among different operator networks can be realized, and continuity of IOT service is ensured.

Description

technical field

[0001] The present invention relates to communication technology, in particular to a method and device for operator network switching. Background technique

[0002] With the popularization of Internet of Things technology, more and more traditional commodities such as automobiles, smart meters, consumer electronics equipment and monitoring equipment are embedded with sensors and communication modules to become Internet of Things terminals. These IoT terminals usually use the operator's mobile network to communicate with the IoT management platform to complete specific tasks.

[0003] The working environment of IoT terminals is often unattended, high temperature, high humidity, frequent vibration and shaking, etc., which is more complex and harsh than the working environment of traditional mobile terminals. Moreover, the Internet of Things terminal cannot connect to the mobile network of the current operator due to base station failure or working environment ...
