The present invention relates to a method and system for switching network connections according to connection quality, and in particular, to provide a method for a portable device to automatically select a network connection according to a connection quality information of each endpoint. system.

When a computer device uses wireless communication to connect to the Internet, it will connect to the Internet through a wireless network base station. If accessing the Internet through a wireless network base station in a public area, such access points may be called hot spots, wireless networks. The base station generally performs the routing work, and the packets generated by the devices in the regional network are connected to other domains according to the destination route.

When the user operates the computer device to connect to the wireless local area network, the conventional method will scan the access point of the nearby hotspot, base station, etc. through the wireless network in the computer device, if it is once connected and recorded. The access point can be automatically connected, but once the access point is reachable, or the signal is weak enough to be disconnected, the wireless network may automatically search for the next range. In addition to the access point in the automatic connection record, the general user needs to restart the wireless network to thread, re-scan and establish the connection.

The general mobile device can simultaneously have the connection capability of mobile communication and wireless local area network (such as WiFi ^TM ), and the user can access the Internet through two different communication networks: mobile network or wireless local area network. When switching between two different communication networks, in addition to manual operation by the user, the conventional technology of automatic switching is wireless local area network priority, and the mobile device will automatically try to connect to the wireless area when the mobile device enters the set wireless local area network range. The base station of the network is authenticated and connected, and once the connection is successful, the network is switched to the wireless local area network.

However, there are still several problems in the prior art. For example, in a network environment that is not set under the wireless local area network, the user needs to manually select the base station to be connected, and through its authentication, can access other domains, resulting in operation. The cumbersome and inconvenient, and the prior art in the mobile communication and wireless local area network switching to give priority to the wireless local area network, when the wireless local area network is worse than the mobile communication network will lead to the use of users The experience is getting worse, and users need to manually turn off the wireless LAN to get the network back to the mobile communication network.

In the prior art, service providers (such as 3G, 4G, etc.) have provided a WiFi automatic authentication service because of the demand for consumer fees. Usually, the SIM (Subscriber Identity Module) authentication method is adopted. The user device automatically switches the wireless network base station when the background program is automatically running.

In view of the lack of an effective access point selection mechanism for the connection quality of the prior art, the present disclosure proposes an automatic connection selection method based on the collected quality data collected by the cloud, and related systems, which obtain a return through the network condition. And the connection judging method enables the terminal device adopting the method to automatically switch the network connection according to the network condition, including multiple wireless local area networks between the plurality of mobile communication network base stations according to the connection quality data.

Connection quality data of the access point. After the quality of the connection is sorted, the cloud servo system provides a connection list of the access point of the terminal device, so that the terminal device can obtain the access point with better service quality according to the connection list of the access point, so as to facilitate the connection network. .

In an implementation manner, when the software program of the terminal device determines that the quality of the network connection via the connected access point is lower than a threshold, an automatic switching instruction is executed to switch the access point of the original connection. For another access point; or re-execute the list of access point connections that require the cloud server to provide updates, and automatically establish a connection based on this list.

The access points listed in the above access point connection list are sorted according to the health of the connection quality data, and the connection quality data according to the health ranking includes the latest connection quantity, flow rate, and access of each access point. Point load and the occupation of the external connection bandwidth of each access point.

In an embodiment of the system, the automatic connection selection system according to the connection quality data collected by the cloud includes the cloud server system and the software program stored in the terminal device.

The cloud servo system mainly includes a database that records connection quality data of a plurality of access points, a receiving terminal device transmits an access point scan list, and establishes an access point connection list according to the connection quality data of the requested access point. The request processing unit, the query unit for querying the connection quality data of the access point, the access point detecting unit for periodically connecting each access point to obtain the latest connection quality data of each access point, and a sorting unit are Sorting according to the connection quality data of one or more access points in the database obtained by the access point scan list, and generating the foregoing health ranking.

FIG. 5 is a view showing an embodiment of a processing flow of the cloud servo system in the automatic connection selection method of the connection quality data collected by the cloud according to the present invention.

Beginning in step S501, the cloud server system receives an inquiry request from the terminal device, and the inquiry request includes the identification data (source source) of the terminal device, and further includes a scan list of the access points near the location of the terminal device.

Then, in step S503, the relevant access point information is obtained from the query request, including the identifier of each access point, so in the cloud server system, the database can be compared according to the access point obtained from the terminal device.

After sorting according to the connection quality data of the access points, an access point connection list is established, as in step S507, and the list is transmitted to each of the requesting terminal devices.

When the cloud servo system sorts the connection quality data of these access points, it will comprehensively consider the latest connection number (number of connected users), traffic (user bandwidth usage), and load of each access point of each access point. And the occupation of the external connection bandwidth of each access point (estimating the remaining available bandwidth). For other considerations, for example, the wireless terminal bandwidth estimation method of the access point can estimate the available bandwidth by using the current data amount, the packet loss ratio (PLR) and the error rate; the access point is connected to the backbone network. The wired terminal can also calculate the data volume and data loss rate currently used, and even add the connection fee of the terminal device user on the mobile communication network, the selection of the carrier, etc., and the user can adjust various items through the software program.

In particular, the plurality of access points recorded in the access point connection list may have a health ranking, and then, in step S609, the terminal device automatically stores the file through the software program. Take one of the access points to establish a connection; if you refer to the health ranking, you will automatically try to connect to the access points in the list.

Figure 7 is a diagram showing an embodiment of a software processing flow of a terminal device.

The software program is started by the terminal device (step S701), the software program first scans the access point (step S703), and connects the server (step S705), and simultaneously scans the access point. The generated access point scan list is transmitted to the cloud servo system (step S707). Details can be found in the above embodiments.

Then, after the operation of the cloud servo system, a list of access point connections sorted according to the connection quality data of the access point is generated, and transmitted to the terminal device, and the software program receives and obtains the list of access points (step S709), that is, According to the sequence, the lines are sequentially connected (step S711), and it is sequentially determined whether the connected access points are successfully connected. (Step S713), if not, proceed to the next access point connection (step S711); if the connection is successful, continue to determine whether the connection quality of the access point is lower than a software preset or User-defined threshold? (Step S715), if it is not below the threshold, indicating that the quality is still within the acceptable range, maintaining the original connection, and continuing to judge whether the connection quality is lower than the threshold.

When the software program attempts to use the connection access point in the order of the obtained connection list, the new access point scan list can be re-established, and the connection list suggested by the cloud servo system can be retrieved.

The threshold can be set according to the aforementioned connection quality data, or only for the signal strength, bandwidth and other parameters. The situation may be that the user carrying the terminal device has left the original connection access point to a certain distance, and it is judged that the connection quality has fallen below the threshold. At this time, an automatic switching instruction is executed, and the software program may continue to try other items in the list. The connection point of the access point is switched from the access point of the original connection to another access point; or, as shown in this embodiment, returning to step S703, re-scanning the access point, establishing a scan list, and obtaining a cloud server Steps such as the access point connection list provided by the system continue to try the next phase of the connection.

When the user carries the terminal device to roam between the base stations, in the above steps S713 and S715, the software program immediately grasps the connection status and can automatically switch the network connection, so the connection connection and the acquisition should be performed periodically. Take a list of points, etc., in which the periodic interval of connection detection is not limited to a specific time. The longer the interval, the lower the sensitivity of network switching. The shorter the interval, the higher the sensitivity, but it may still affect the terminal device. Operation.
