detailed description

The invention will be described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 , a method for configuring a network port of a network device according to an embodiment of the present invention includes:

S11, detecting a usage status of the network port of the network device, where the network port type of the network port includes a WAN port or a LAN port;

S12. If the network port of the network device is in an idle state, change the network port type of the network port to perform network connection by changing the type of the network port.

The network port configuration method of the network device provided by the embodiment of the present invention can detect the network port usage state of the network device. When the network device works normally but the network port usage state is idle state, the network port can be changed. The network port type is used to connect to the network through the network port after the type is changed. In this way, by changing (converting) the type of the network port, the network port that is originally redundant and in the idle state can perform network connection and provide corresponding service in another manner, thereby effectively improving the network port utilization of the network device. .

It should be noted that the network port type can be a WAN port type, that is, a network port type used for connecting to an external Internet, such as ADSL (Asymmetric Digital Subscriber Line), DDN (Digital Data Network). Network, Ethernet, and other access lines; the network port type can also be a LAN port type, that is, a network port type used to connect to a local network device, and is mainly connected to a switch, hub, or PC in the home. The change mentioned in this embodiment The network port type is essentially software configuration so that the same network port can be switched between the above two types.

This network port configuration method is applicable to all devices with network ports (such as routers), but it is especially suitable for network devices with one and only one network port, such as smart set-top boxes or U-fi with network ports. In general, many network devices can provide both wired and wireless Internet access. For example, for a smart set-top box, the network port type is WAN port, which can be connected to the Internet through a network port, or can be connected to the Internet through a wireless connection. Features. For a U-fi with a network port, the network port type is a LAN port. It can be connected to the terminal through the network port to provide Internet access for the terminal, or wirelessly connect with the terminal to provide wifi service for the terminal.

The following describes the network port configuration method provided by the present invention in detail by using an intelligent set top box and U-fi as an example.

Specifically, for the smart set top box, when the network port type is the WAN port, the detecting the use status of the network port of the network device in the step S11 may specifically include:

Detecting whether the network port of the network device is connected to the Internet;

When the network port of the network device is not connected to the Internet, determining that the usage status of the network port of the network device is an idle state;

Correspondingly, changing the network port type of the network port in step S12 may specifically include:

Change the network port type from WAN port to LAN port.

In this embodiment, detecting whether the network port of the network device is connected to the Internet may be implemented by querying the port status of the system and attempting to send an access request to the Internet.

For example, when there are other devices connected to the network port, an eth0 logical port will appear. When the network port is not connected to other devices, the eth0 logical port does not exist in the system. Therefore, you can first determine whether the eth0 port exists. Whether the network port is connected to other devices. If it is determined that the network port is connected to other devices, it can further determine whether the connected other device is an Internet server or an Internet terminal by sending an access request to the Internet. If you access the internet please If the response is obtained, it is determined that the network port is connected to the Internet server, otherwise it is determined that the network port is connected to the ordinary Internet terminal.

Specifically, the type conversion between the WAN port and the LAN port, whether it is a Linux-based device or a Windows-based device, can be implemented by software configuration. For example, for Android systems, the shell script that switches from the WAN port to the LAN port can look like this:

/system/bin/iptables_droid-t nat–F;//Clear the Internet rules stored in the nat table;

Echo 0> / proc / sys / net / ipv4 / ip_forward ; / / disable the forwarding function;

Echo 1> / proc / sys / net / ipv4 / ip_forward ; / / will open the forwarding function.

In the above code, the current nat table in the network port is first cleared, so as to clear various Internet access rules stored in the nat table when the WAN port is used, and then the forwarding function is restarted by prohibiting the forwarding function from being restarted, so that The network port has a data forwarding function to forward data to the Internet terminal connected thereto, thereby implementing the function of the LAN port.

For other language systems, although the system is different, it can achieve the corresponding switch.

In an embodiment, after the network port type of the network port is changed, the network port configuration method provided by the embodiment of the present invention may further include the following steps:

Connect the network port after the type change to the terminal;

The network device is wirelessly connected to the Internet such that the terminal is connected to the Internet through the network device.

That is to say, the network port of the smart set-top box is originally a WAN type. After the network port is found to be in an idle state, the type of the network port is modified to improve the network port usage. The port becomes a LAN port. In this way, the network port can be connected to the terminal. When the smart set-top box is connected to the Internet through a wireless method such as 3G or wifi, the network port is not left idle, but serves as a LAN type network port, which can be used for various The terminal provides Internet access.

The network port configuration method provided by the present invention can enable the network port to access the Internet through Wi-Fi and 3G. In the case of its use. For example, there is a PC in the home and a Box product connected to the Internet through a 3G mobile network, and this PC does not support wireless Internet access. Then, if the PC is required to access the Internet, the network port configuration method provided by the present invention can be used to change the network port type of the box, and then the PC is connected to the network port, so that the PC can share the 3G mobile network of the Box.

On the contrary, if the user needs to use the smart set-top box and is not connected to the Internet through wireless means such as 3G or wifi, the network port on the smart set-top box can be set to the WAN port type, and the smart set-top box can be connected to the Internet through the network port. .

Optionally, switching from the LAN port to the WAN port shell script can be as follows:

Echo 0>/proc/sys/net/ipv4/ip_forward. //Disable the forwarding function.

In the above code, the current nat table in the network port is first cleared, so as to clear various forwarding rules stored in the nat table when the LAN port is previously used, and then the forwarding function is disabled, thereby implementing the function of the WAN port.

In the embodiment of the present invention, the network port device of the box can be effectively utilized, and the state of the network port can be changed, so that the box product can provide network services for other devices through the network port. This is especially useful for devices that do not have a wireless network card.

The configuration and application process of the Box network port are described in detail below through specific embodiments. Box refers to the smart TV box or smart set-top box, which can be connected to the TV through HDMI (High Definition Multimedia Interface), turn ordinary TV into smart TV, and install applications, Internet, games and so on. As shown in FIG. 2, the Box may include three modules: a communication module (wifi or 3G), a network port control module, and a network port module.

Communication module

The module can provide Wi-Fi and 3G connection. There are two main functions: a. When the network port type is WAN port, it provides Internet service for Box products, and Box products connect to the Internet through this module. The connection diagram is shown in Figure 3. b. When the network port type is a LAN port and is connected to other devices, the module can also provide network services for other devices through the network port at this time. The connection diagram is shown in Figure 4.

Network port control module

This module mainly controls the state of the network port. In the software system, the network port WAN port and the LAN port are switched. The user can set the type of network port according to the usage in the module of the Box product: the WAN port type can provide Internet access for the Box product through the network port. The LAN port type can be networked through the communication module of the Box product, and the network port is used to enable other devices to share the network service of the Box product.

Network port module

This module is mainly based on different network port types set by the network port control module. Different network port types correspond to different functions: a. WAN port type, providing Internet service for Box products, and Box products are connected to the Internet through the module to connect to the Internet. b. LAN port type. When using wifi or 3G Internet access, the Box can use this network port to connect to other devices to share Internet access services for other devices.

Since the WAN port is a function of the usual Box products, the workflow is basically the same for each Box product. Therefore, the following mainly uses the network port type as the LAN port, and the system introduces the workflow and implementation method of the method for the Android system. However, the method is not limited to the Android system and the implementation method.

As shown in FIG. 5, in this embodiment, the method for configuring a network port of a box may include the following steps:

Step S201, open wifi to connect to the wifi network, or open the 3G connection mobile network, so that the box connects to the Internet through wifi or 3G.

This step can be achieved by: 1) entering the system's own setup program to open wifi and connect to the wifi network or open the mobile data network. 2) Manually implement wifi opening and connecting using the relevant api method in WifiManager.java in the framework. Use Phone.java, ConnectivityManager.java in the framework to manually open the mobile data network. The specific implementation of these two methods can refer to the Setting source and Phone program in the Android source code to achieve the source code.

Step S202, specifying an uplink channel;

Optionally, you can manually select wifi or 3G as the uplink channel to provide network services to the network port. You can also use the software system to automatically determine how the user is currently connected to the Internet and then automatically specify the upstream channel.

This step implements the following shell script:

/system/bin/iptables_droid-t nat-F

/system/bin/iptables_droid-t nat-A POSTROUTING-o ppp0-j MASQUERADE;

The oblique black body part is the system port name corresponding to the uplink channel, and only the corresponding system port name is required to replace the oblique black body part for selecting different uplink channels. For example, if the current wifi is selected as the uplink channel, and the corresponding port of the wifi in the system is named wlan0, then only the oblique black body part is replaced by wlan0. which is:

/system/bin/iptables_droid-t nat-A POSTROUTING-o wlan0-j MASQUERADE;

Optionally, when the uplink channel is specified by the automatic setting method, the current networking state may be obtained by using the following code to set the corresponding port:

ConnectivityManager conn=(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_S ERVICE);

Conn.getActiveNetworkinfo().getTypeName();

Through the program, the current network name can be obtained, thereby judging whether the current network is a wifi or a mobile network, and then correspondingly specifying.

As for how to call from java to shell script, you can refer to the related methods in init.rc in the Android system.

In step S203, it is determined whether the uplink network is successfully designated in S202. If the designated uplink network is not opened or connected, S205 is performed; if successful, S204 is performed.

Step S204: Set the network port type, and switch the network port type WAN to the LAN, so that the network port can provide network services to other connected devices, and continue to execute S206.

Switching from the WAN port to the LAN port shell script is as follows:

/system/bin/iptables_droid-t nat-F

Echo 0>/proc/sys/net/ipv4/ip_forward

Echo 1>/proc/sys/net/ipv4/ip_forward

Switching from the LAN port to the WAN port shell script is as follows:

/system/bin/iptables_droid-t nat-F

Echo 0>/proc/sys/net/ipv4/ip_forward;

Step S205, prompting to specify the reason for the failure, and executing S112.

Step S206: Connecting other terminals, using a network cable to connect the Box network port with the network ports of other terminals, and establishing a physical connection between the two devices to provide basic support for the network port sharing network service.

Step S207: It is determined whether the connection between the network port of the Box and other network devices in S206 is successful. If it fails, S208 is performed; if successful, S209 is performed.

The implementation of this step is as follows:

Through the network port, for example, eht0 obtains the status of the port through the bottom layer, and determines whether the physical connection has been made. In the android human-computer interaction interface UI can interact with the underlying network port and the driver through jni to know the port connection status.

Step S208, prompting the connection failure reason, and executing S112.

Step S209, dynamically assigning an Internet Protocol IP address to other terminals to provide basic support for the network service. Other terminals can use this IP address as their own IP.

The implementation of this step is as follows:

Dynamic Map Assignment IP uses DHCP (Dynamic Host Configuration Protocol) to dynamically configure the client's information. Box as DHCP The server, when the DHCP server receives the information of the IP address requested by the client, searches the database for a valid IP address to be provided to the client. If yes, this IP tag is broadcast to broadcast a DHCP Offer message. The message mainly includes: the MAC address of the client, the legal IP address provided, the subnet mask, the lease term, and the server IP address. The specific DHCP server implementation can refer to the implementation in other systems.

Step S210: Determine whether the third party device allocates the dynamic IP is successful, if yes, execute S111; if successful, the other device starts to share the network through the box, and execute S212.

In step S211, the IP allocation failure reason is prompted. If the IP address fails to be assigned in S210, the user is prompted to fail to give a failure reason, and S212 is performed.

Step S212, ending.

After the uplink channel is implemented and the IP is allocated to other devices, other devices (such as ordinary PCs) can access the Internet through the network sharing box.

It should be noted that the network port configuration method provided by the embodiment of the present invention is mainly described by using the Android system as an example, but the method is not limited thereto.

Specifically, for the U-fi, the built-in network port is generally a LAN type. Then, in step S11, detecting whether the network port of the network device is in an idle state may specifically include:

The network port of the network device is connected to the terminal. Optionally, in this step, whether the eth0 port exists in the system can be used to determine whether the network port is connected to other devices. If the eth0 port is available, the network port is connected to other devices. If eth0 does not exist, the network port is not connected to other devices. On the premise that the eth0 port is connected to other devices, the network port type may be attempted to be designated as a WAN port and an access request is sent to the Internet to determine whether the network port is connected to the Internet or a common Internet terminal. If the request to access the Internet is responded, it is determined that the network port is connected to the Internet, otherwise it is determined that the network port is connected to the ordinary Internet terminal.

When the network port of the network device is not connected to the terminal, determining that the usage status of the network port of the network device is an idle state;

Correspondingly, changing the network port type of the network port in step S12 may specifically include: changing the network port type from a LAN port to a WAN port.

In an embodiment, after the changing the network port type of the network port, the method further includes:

Connect the network port after the change type to the Internet;

The network device is wirelessly connected to the terminal such that the terminal is connected to the Internet through the network device.

In this embodiment, by changing the network port of the U-fi to the WAN port type, the U-fi can use the network port to connect to the Internet, and then serve as a wireless hotspot to provide wifi services to other terminals.
