A network switching method and device

Abstract

The present invention provides a network switching method, comprising: A. respectively collecting third-generation mobile communication (3G) network signals and wireless local area network (WLAN) signals; Connection status information; B. Determine whether network switching is required according to the collection results, congestion level information, and the current connection status information of the terminal. If so, perform the switching operation, otherwise, do not perform the switching operation; C. After a predetermined period of time, repeat Execute step A. The invention also discloses a network switching device. The application of the method and device of the present invention can facilitate the use of the user and provide the optimal network to the user.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a network switching method and device. Background technique [0002] With the continuous deepening of the industry's informatization process and the third-generation mobile communication (3G, 3rd-Generation) network, such as Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) network and broadband code With the official use of WCDMA (Wideband Code Division Multiple Access) network, the speed of wireless Internet access has been greatly improved compared with the traditional 2G network, which has brought great convenience to users who use wireless networks. [0003] In order to further facilitate users, wireless local area networks (WLAN, Wireless Local Area Networks) have also been set up in places where the crowds are concentrated in some urban areas, so as to alleviate the drawbacks that the 3G network can...

Problems solved by technology

[0004] Compared with WLAN network, 3G network has its own advantages and disadvantages. For example, for 3G network, its coverage area is larger, and it is self-adaptive to 2G network, but the tariff is too high, and the network speed is slow, while WLAN network is The tariff is low and the network speed is fast, but the coverage area is too small, limited by transmission power and other aspects, it can only cover a limited area; in addition, the quality of the signal will also affect the network speed

It can be seen that in the existing switching methods, the user needs to complete the switching manually, and the user needs to determine whether switching is required based on his own feeling. The system cannot complete the switching by itself or guide the user to complete the switching according to the signal quality. The use of the network brings great inconvenience, and the user's feeling may be inaccurate, resulting in improper switching, that is, the network that is optimal in all aspects cannot be used
