Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terminal access network switching method provided by the embodiment of the present invention is described first. FIG. 1 is a flowchart of a terminal access network handover according to an embodiment of the present invention. This embodiment describes a process flow of the terminal, where the terminal may be intelligent. Such as a terminal or a tablet, the terminal has both WiFi network access capability and cellular network access capability. As shown in FIG. 1, this embodiment includes:

101. The terminal determines whether the WiFi network is currently connected. If the WiFi network is connected, the process proceeds to step 102. If the WiFi network is not connected, the process proceeds to step 104.

The terminal may first determine whether the WiFi function is enabled. If the WiFi function is not enabled, it is determined that the terminal is not currently connected to the WiFi network.

If the terminal has turned on the WiFi function, it is further determined whether the terminal accesses any one of the access points (AP: Access Point). If the terminal does not access any of the access points, it can be determined that the terminal is not currently connected to the WiFi network.

If the terminal accesses any of the access points, it is determined that the terminal is currently connected to the WiFi network.

Among them, the wireless access point is a wireless network access point, commonly known as "hot spot." There are mainly routing switching access integrated devices and pure access point devices. The integrated device performs access and routing work. The pure access device is only responsible for wireless client access. The pure access device is usually used as a wireless network extension, and other APs. Or the primary AP is connected to expand the wireless coverage, and the integrated device is generally the core of the wireless network. A wireless AP is an access point that uses a wireless device (a mobile device such as a mobile device or a wireless device such as a notebook computer) to enter a wired network, and is mainly used in a broadband home, a building interior, a campus interior, a campus interior, and a warehouse, a factory, and the like that require wireless monitoring. Places, typical distances cover tens of meters to hundreds of meters, but also can be used for long-distance transmission, the farthest can reach about 30KM, the main technology is IEEE802.11 series. Most wireless APs also have an access point client mode (AP client) that can be wirelessly connected to other APs to extend the coverage of the network.

102. The terminal detects whether the WiFi network is connected to the Internet; if yes, proceeds to step 103; if not, proceeds to step 104.

Wherein, detecting whether the WiFi network is connected to the Internet can be performed in various ways, specifically, pinging a server located in the Internet, for example, ping www.baidu.com, at this time, if receiving a response from the server corresponding to www.baidu.com, It means that the current terminal can communicate with the server corresponding to www.baidu.com. Since the server corresponding to www.baidu.com is located on the Internet, it can be determined that the WiFi network is connected to the Internet. Of course, if there is no response, it can be proved that the WiFi network does not have an Internet connection.

It should be noted that, in some embodiments, in order to ensure the accuracy of determining whether the terminal is connected to the Internet, a plurality of servers located on the Internet may communicate with each other, that is, a server fault located in the Internet may be excluded to cause an error to be detected. Happening.

103. Access the Internet through the WiFi network.

If the WiFi network is connected to the Internet, the WiFi network is used as a path for Internet connection, thereby accessing the Internet through the WiFi network, that is, all Internet traffic is transmitted through the WiFi network.

104. Accessing the Internet through a cellular network.

If the WiFi network is not connected to the Internet, the Internet is accessed via the cellular network, ie all Internet traffic is transmitted over the cellular network.

In the embodiment of the present invention, the terminal can detect the connection between the WiFi network and the Internet, so that when the WiFi network connected to the terminal cannot be connected to the Internet, the terminal accesses the Internet through the cellular network, so that the terminal can always access the Internet and improve the user's use of the terminal. User experience of accessing the network.

FIG. 2 is a flowchart of a terminal access network handover according to another embodiment of the present invention. As shown in FIG. 2, the embodiment includes:

201. The terminal determines whether the WiFi network is currently connected. If the WiFi network is connected, the process proceeds to step 202. If the WiFi network is not connected, the process proceeds to step 205.

202. Send a detection request to a detection server located on the Internet through a WiFi network.

In one embodiment, the detection request can be a ping request. The detection server may be set by the terminal manufacturer itself or may be another server located in the Internet. For example, in one embodiment, a ping method is used, for example, ping www.baidu.com. At this time, if a response from the server corresponding to www.baidu.com is received, the current terminal can be associated with www.baidu. Com The corresponding server communicates. Since the server corresponding to www.baidu.com is located on the Internet, it can be determined that the WiFi network is connected to the Internet. Of course, if there is no response, it can be proved that the WiFi network does not have an Internet connection.

203. Determine whether the detection response of the detection server is received within the preset time.

If the detection response of the detection server is received within the preset time, the WiFi network can be connected to the Internet, and the process proceeds to step 204; if the detection response of the detection server is not received within the preset time, the WiFi network cannot be connected to the Internet. Going to step 205;

It should be noted that, in some embodiments, in order to ensure the accuracy of determining whether the terminal is connected to the Internet, a plurality of servers located on the Internet may communicate with each other, that is, a server fault located in the Internet may be excluded to cause an error to be detected. Happening. That is, steps 202 to 203 can be performed multiple times in a loop, and as long as the result of any one of the times is that the detection response of the detection server is received, it can be said that the WiFi network is connected to the Internet.

204. Access the Internet through the WiFi network. End the process.

205. Accessing the Internet through a cellular network.

In another embodiment of the present invention, the user may pre-set whether to allow the terminal to automatically perform the switching of the access network, that is, an automatic switch can be set in the setting menu of the terminal system, and the user can set according to his own needs. Select whether to turn the automatic switch on. For example, if the user's Internet connection needs are relatively strong, and the user can also bear the cost of accessing the Internet through the cellular network, the user can choose to turn on the automatic switch; or, although the user's Internet connection needs are strong, but does not want to bear through the cellular network. The user can choose to turn off the automatic switch when the fee is generated by accessing the Internet; or if the user's Internet connection demand is weak, the user can choose to turn off the automatic switch. switch. It can be understood that in order to avoid the additional cost of using the cellular network to access the Internet for the user, the system should turn off the automatic switch by default.

In this case, before the terminal accesses the Internet through the cellular network, it should also judge whether the preset automatic switch is turned on;

If the automatic switch is off, it means that the user does not want to access the Internet through the cellular network if there is a WiFi network, even if the current WiFi network is not connected to the Internet.

In another embodiment of the present invention, after the user is preset to allow the terminal to automatically perform the handover of the access network, the user may further set how much data can be generated through the cellular network when the WiFi network is available, that is, The data volume setting menu can be set in the setting menu of the terminal system, and the user can set the upper limit value of the data amount according to his own needs or withstand capability, and the data amount can also set a single upper limit value, and a certain time period. , for example, the upper limit of the cumulative amount of data for one day, one week, or one month. For example, the user can set the amount of data generated in a single generation to not exceed 10M, the amount of data in one week cannot exceed 100M, the amount of data in one month cannot exceed 1G, and so on. Understandably, in order to reduce the amount of user operations, the system can also set a default value, which should be a value that most users can end, for example, it can be 10M.

In this case, the terminal may further determine the amount of data that requires Internet interaction before accessing the Internet through the cellular network; and then determine whether the amount of data is greater than a preset amount; if the amount of data is less than or equal to the pre- It is only necessary to access the Internet through a cellular network. If the amount of data is greater than the preset amount, the Internet is not accessed through the cellular network.

The confirmation of the amount of data exchanged by the Internet may be confirmed by the size of the file to be sent or received. For example, if a file needs to be sent, the size of the file is 9M, and the amount of data to be interacted may be determined to be less than the preset number 10, thereby The Internet can be accessed through a cellular network. On the other hand, if it is necessary to receive a file whose size is 11M, it can be determined that the amount of data requiring Internet interaction is greater than the preset number 10, so that the Internet is not accessed through the cellular network.

In some embodiments, in order to improve the usage of the user, the selection information may be displayed on the display of the terminal before the Internet is accessed through the cellular network, so that the user can select whether to access the Internet through the cellular network;

The Internet is accessed through the cellular network if the user's confirmation message is received. If the user's confirmation information is not received, or the user's rejection information is received, the Internet is not accessed through the cellular network.

The content of the selection information displayed on the display screen of the terminal may include: an Internet connection status of the current WiFi network, a situation of the amount of data required for Internet interaction, and the like, and the user is determined according to the content whether to allow access to the Internet through the cellular network.

For example, in one embodiment, a ping method is used, for example, ping www.baidu.com. At this time, if a response from the server corresponding to www.baidu.com is received, the current terminal can be associated with www.baidu. The server corresponding to com communicates, because the server corresponding to www.baidu.com is located on the Internet, It is then meaningless to determine that the WiFi network is connected to the Internet. Of course, if there is no response, it can be proved that the WiFi network does not have an Internet connection. If the detection response of the detection server is received within the preset time, the WiFi network can be connected to the Internet; if the detection response of the detection server is not received within the preset time, the WiFi network cannot be connected to the Internet.

It should be noted that, in some embodiments, in order to ensure the accuracy of determining whether the terminal is connected to the Internet, a plurality of servers located on the Internet may communicate with each other, that is, a server fault located in the Internet may be excluded to cause an error to be detected. Happening. The detection by the detecting unit 302 can be performed multiple times, and as long as the result of any one of the times is that the detection response of the detecting server is received, it can be said that the WiFi network is connected to the Internet.

In another embodiment of the present invention, the user may pre-set whether to allow the terminal to automatically perform the switching of the access network, that is, an automatic switch can be set in the setting menu of the terminal system, and the user can set according to his own needs. Select whether to turn the automatic switch on. For example, if the user's Internet connection needs are relatively strong, and the user can also bear the cost of accessing the Internet through the cellular network, the user can choose to turn on the automatic switch; or, although the user's Internet connection needs are strong, but does not want to bear through the cellular network. The user may choose to turn off the automatic switch when the fee is generated by accessing the Internet; or the user's Internet connection demand is weak, the user may choose to turn off the automatic switch. It can be understood that in order to avoid the additional cost of using the cellular network to access the Internet for the user, the system should turn off the automatic switch by default.

In this case, the determining unit 302 is further configured to: determine whether the preset automatic switch is turned on; and the connecting unit is specifically configured to: after the determining unit determines that the automatic switch is turned on, The cellular network accesses the Internet.
