In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

FIG. 1 shows a flow chart of a network switching method provided in the first embodiment of the present invention, which is described in detail as follows:

Step S11, detecting whether there is a connectable wifi hotspot.

Specifically, when the user turns on the wifi connection function (such as WLAN) of the terminal device, the terminal device receives a wifi connection instruction, and the terminal device detects whether there is a connectable wifi hotspot within a preset range.

Specifically, when the terminal device is a mobile terminal, a schematic diagram of the mobile terminal is shown in FIG. 2 . In FIG.

Optionally, before the step S11, including:

The network status information of the currently connected network is acquired, and the network status information includes information about whether the currently connected network can be connected to the network, and information about the quality of the network. In this way, step S11 is executed when it is judged according to the network status information that the currently connected network cannot access the network, or the network quality deteriorates (for example, when it is less than a preset quality index).

Step S12, when there is no wifi hotspot that can be connected, it is judged whether there is an available data network.

Among them, the available data network refers to its corresponding transmission control protocol (Transmission Control Protocol, tcp), hypertext transfer protocol (HyperText Transfer Protocol, http), packet loss rate, received signal strength indication (Received Signal Strength Indication, rssi) One or more of them meet the preset network availability conditions.

Optionally, since local wifi hotspots do not generate roaming charges, therefore, in order to save costs, the network switching method further includes:

A1. When there is a wifi hotspot that can be connected, obtain the current geographic location information of the terminal device.

A2. According to the current geographic location information of the terminal device, judge whether the current location of the terminal device belongs to the operator's cellular network where the terminal device has registered. If so, connect to the wifi hotspot; if not, do not connect to the mobile network Describe wifi hotspots.

Since the existing wifi hotspots that can be connected may also be wifi hotspots in other places, that is, they belong to roaming wifi hotspots. Therefore, only when it is judged that the wifi hotspot belongs to the local wifi hotspot, the wifi hotspot is connected, otherwise, the wifi hotspot is not connected. Hotspots, so as to avoid roaming charges caused by using wif hotspots across regions.

Step S13, when there is an available data network, acquire the current geographic location information of the terminal device.

Specifically, the current geographic location information of the terminal device may be acquired through Global Navigation Satellite System (Global Navigation Satellite System, GNSS) or network positioning.

When the user selects manual switching, the attribute of the network switching of the terminal device is manual switching. When the user selects automatic When switching, the attribute of the network switching of the terminal equipment is automatic switching.

B2. When the attribute of network switching is manual switching, prompt the user to connect to the available data network, and connect to the available data network when a connection instruction is received. Specifically, a prompt box pops up to prompt the user whether to choose to connect to an available data network. For example, when the user clicks the "Confirm" button (or other buttons indicating confirmation information), the terminal device receives the connection instruction and executes the connection instruction. When the user clicks the "cancel" button (or other buttons indicating cancellation information), the terminal device receives a no-connection instruction.

B3. When the attribute of network switching is automatic switching, automatically connect to the available data network. Further, a prompt message indicating that the current network is a data network is displayed. Although the connection to the local data network does not generate roaming charges, certain charges are still generated, therefore, a prompt message is displayed to let the user know.

Optionally, when the current location of the terminal device is not the home of the operator's cellular network where the terminal device has registered, the available data network is not connected. When it is determined that the terminal device belongs to a foreign country, it does not connect to an available data network to avoid roaming charges. Further, if the user manually connects to the roaming data network, the network switching method further includes: detecting whether an instruction from the user to establish a connection with the available data network is received; When an instruction is made to establish a connection with the data network, the user is prompted that the available data network is a roaming data network.

Further, an option pops up so that the user can further confirm whether to connect to the available data network. When the user clicks the option "Confirm", the terminal device will establish a connection with the available data network. When the user clicks "Cancel" After selecting the option, the terminal device will not establish a connection with said available data network.

C2. Determine whether the position distance between the acquired current geographic location information of the terminal device and the last acquired geographic location information of the terminal device exceeds a preset distance threshold.

C3. When the distance between the acquired current geographic location information of the terminal device and the last acquired geographic location information of the terminal device exceeds a preset distance threshold, poll to detect whether there is a current location with the terminal device If there is a matching available wifi hotspot, switch from the available data network to the available wifi hotspot. Of course, if the distance between the acquired current geographic location information of the terminal device and the last acquired geographic location information of the terminal device does not exceed the preset distance threshold, then no polling is performed to detect whether there is any contact with the terminal device.

When the available wifi hotspots are wifi hotspots that do not require authentication information, the wifi hotspot is automatically connected. If there is a wifi hotspot of information, then connect to the wifi hotspot after obtaining the authentication information of the wifi hotspot.

In the first embodiment of the present invention, it is detected whether there is a Wi-Fi hotspot that can be connected, and when there is no Wi-Fi hotspot that can be connected, it is judged whether there is an available data network, and when there is an available data network, the current geographic location information of the terminal device is obtained, According to the current geographic location information of the terminal device, it is judged whether the current location of the terminal device is the home of the operator's cellular network where the terminal device has registered, and the current location of the terminal device is the registered location of the terminal device. When the carrier's cellular network belongs, connect to the available data network. Since the current location of the terminal device is the home of the operator's cellular network that the terminal device has registered with, it indicates that the available data network is a local data network, at this time, connecting to the available data network will not occur due to roaming In addition, because there is no Wi-Fi hotspot that can be connected to the data network, it can ensure that the terminal device can access the network in time, keep the network smooth, and improve the user's good online experience.
