Network connection method, device and terminal

Abstract

The invention discloses a network connection method and device and a terminal. The method comprises the following steps: detecting registration information of a current user identification module, andobtaining at least one network type of an operator corresponding to the registration information and connection priority of the network type; and carrying out network registration according to the connection priority. The method is characterized by determining the priority of the network type first before network connection, and when carrying out registration according to the priority of the network type, setting the network type having a registration error to be suspended when an error occurs in the registration, thereby preventing continuing to carry out network search based on the networktype having the registration error when the error occurs in the registration; and besides, when registration and connection are carried out based on other network types having higher priority, networkconnection time is saved, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a network connection method, device and terminal. Background technique [0002] With the continuous increase of people's communication needs, mobile communication technology has achieved unprecedented development, and more and more electronic devices have entered people's lives, such as mobile phones, tablet computers, notebook computers, etc., especially now the development of mobile communication, There are more and more network standards for mobile communication networks, and mobile terminals can support multiple network standards. Greatly meet people's needs for communication. [0003] Mobile terminals in the existing standard full network mode search the network before accessing the operator's network. After the network search is completed, the network is registered according to the terminal network mode. The order of network search is generally from 4G to...

[0003] Mobile terminals in the existing standard full network mode search the network before accessing the operator's network. After the network search is completed, the network is registered according to the terminal network mode. The order of network search is generally from 4G to 3G to 2G for full-band search network, and when the signal 4G signal is weak, the 4G network and the 3G / 2G network switch back and forth. Sometimes when the network registration error or registration timeout occurs, it will search the network again and register again, resulting in slow search and registration speed of the mobile terminal. , affecting user experience
