Abstract

The invention provides a network switching method including a terminal connecting wireless local area network. After a terminal is connected to the wireless local area network, the terminal judges whether the wireless local area network can visit Internet or not. If the local area network cannot visit the Internet, the terminal disconnects with the wireless local area network and uses a mobile network. According to the invention, the terminal can judge whether the wireless local area network can visit Internet or not. If the local area network cannot visit the Internet, the terminal can use the mobile terminal, so that communication can be guaranteed and service interruption is avoided. Therefore, user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a network switching method and a terminal. Background technique [0002] At present, many smart terminals support access to mobile networks and wireless local area networks. Smart terminals can be mobile devices such as mobile phones or tablet computers. Mobile networks can be 2G networks, 3G networks or Long Term Evolution (LTE) networks. The local area network may include a WiFi network, from which the user may select a network for use, or the smart terminal may automatically select a network for use according to surrounding network conditions. For example, the 3G mode and the WiFi mode of the smart terminal are turned on at the same time. When the user carries the smart terminal and enters a hotspot area that has been accessed from outside the wireless LAN coverage area, the smart terminal will automatically switch to the WiFi network. However, when the...
