The invention provides a network switching method and a device. The method can include: when a terminal communicates abnormally under a first network, searching a base station of a second network; when a terminal communicates abnormally under the first network, searching a base station of the second network. Wherein the first network is a second generation mobile phone communication specification2G network, and the second network is a narrowband Internet of Things NB-Io network; Alternatively, the first network is an NB- An IoT network, the second network being a 2G network; Sending a first connection request to the base station, wherein the first connection request includes a terminal identification to cause the base station to store the terminal identification; Performing authenticationprocessing with the base station to perform network communication with the base station. The scheme is used for solving the problem that the network of the terminal may be abnormal when the network environment of the terminal is changed, and the terminal cannot communicate.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a network switching method and device. Background technique [0002] With the development of communication technology, we provide 2-Generation wireless telephone technology (2G for short) communication network technology and narrowband Internet of Things (NB-IOT for short) communication network technology. Among them, NB-IOT communication network technology is an emerging Internet of Things technology because of its wide coverage, multiple connections, fast speed, low cost, low power consumption and excellent architecture. [0003] In the prior art, a dual-mode module is set in the terminal. The 2G number card can be connected to the dual-mode module of the terminal, so that the terminal can communicate under the 2G network; or, the card of the Internet of Things number can be connected to the dual-mode module of the terminal, so that the terminal can communicate ...
