Description

Technical Field

[0001] The present invention relates to the technical field of network switching, and in particular to a method and device for quickly acquiring and restoring an IP network. Background Art

[0002] Smart home devices such as televisions access the Internet or operator interactive networks through the network. Usually, the operator's private network application is installed on the television to connect to the network.

[0003] Operators have a class of USB external devices to switch networks under program control. USB external devices include network cables and USB network cards. By entering or exiting private network applications to control the on and off of the network cables, the same effect as plugging and unplugging the network cables can be achieved. Network switching is based on USB. The external USB device is a bridge-type device, which does not have complex functions and is low-cost.

[0004] First, the timing of starting the private network application is relatively late. Second, the network is acquired after the application is started. Third, it takes a long time to connect to the network and obtain data to display to the user, resulting in a poor user experience. When the private network application retreats to the background, the renewal of the network IP is not completed by the main body, and the IP address will be disconnected. If the private network application is opened again, the IP network needs to be acquired again, which leads to a very poor user experience. In summary, the network switching of home smart devices such as TVs has the following problems:

[0005] Generally, you should choose a simple bridge USB device, but it also has the disadvantage of simple functions;

[0006] A private network application is needed to complete the work of acquiring and driving the network;

[0007] Private network applications on TV sets generally cannot stay in the background;

[0008] The private network application needs to obtain an IP address again every time it enters;

[0009] The acquisition of IP addresses by private network applications is limited by the network and protocol itself, resulting in a slow speed;

[0010] There will be a significant delay when private network applications access intranet services;

[0011] When using private network applications, users need to wait for a while before they can use them normally when entering for the first time, exiting, and re-entering, which results in a poor experience. Summary of the invention
