Abstract

The invention discloses a communication method and device, relates to the technical field of communication, and is used for solving the problem that part of terminals cannot communicate when moving out of the coverage of a current operator. The method comprises the following steps: firstly, acquiring first signal intensity; then, obtaining a second signal strength; and finally, under the conditionthat the first signal intensity is lower than a first threshold value and the second signal intensity is higher than a second threshold value, enabling the terminal to download the formal code numberof the Yth operator through the preset code number of the Yth operator, wherein the first signal strength is the signal strength between the terminal and the network equipment of the current operator, the second signal strength is the signal strength between the terminal and the network equipment of the Yth operator, and Y is a positive integer.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and device. Background technique [0002] Due to the limitation of factors such as cost and volume, most IoT terminals only support cellular communication technology, and do not support other communication technologies such as Bluetooth or wireless fidelity (WIFI). That is to say, most IoT terminals can only communicate through cellular networks. [0003] In the prior art, when the terminal moves out of the coverage of the current operator, the terminal can no longer communicate through the cellular network of the current operator. At this time, terminals equipped with other communication technologies can communicate through other communication technologies, but most IoT terminals cannot communicate because they only support cellular communication technologies, resulting in the disconnection of IoT services.
