Abstract

The embodiment of the invention provides a network switching method. The network switching method comprises the steps that after a first network is connected, at least two first signal values of the first network are acquired, the average value of the at least two first signal values is calculated, and the average value of first signals is obtained; when the average value of the first signals meets a preset second network connecting condition, the control instruction for connecting a second network is sent; at least two second signal values of the first network are acquired, the average value of the at least two second signal values is calculated, and the average value of second signals is obtained; when the average value of the second signals meets a preset first network disconnecting condition, the control instruction for disconnecting the first network is sent. A method of averaging by multiple metering is used for conducting signal stability assessment on the network, switching misjudgment and ping-pong effect of repeated switching caused by the mobility of a terminal and the instability of network wireless signals are avoided, and the probability of service interruption is effectively lowered. The invention further provides a network switching device and a mobile terminal.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network switching method, a network switching device and a mobile terminal. Background technique [0002] With the increasing demand for data services and the popularization of WIFI (Wireless Fidelity, Wireless Fidelity) networks, operators are currently providing wide area access network services such as 2G / 3G / LTE / 4G, and are also starting to The large-scale deployment of WIFI networks aims to guide users to conduct data services through WIFI networks, thereby alleviating the pressure on the wide area access network. [0003] WAN access network (also called remote network) and WIFI network have their own advantages and disadvantages. WAN access network has better geographical coverage characteristics, good mobility, but high tariff; WIFI network has small coverage and poor mobility. But its Internet speed is high. The user equipment can not only access the Inte...
