Embodiment Construction

[0019] see figure 1 , figure 1 A schematic flowchart of the first embodiment of the switching method between the IPV4 network and the IPV6 network of the present invention.

[0020] The switching method between the IPV4 network described in the present embodiment and the IPV6 network comprises the following steps:

[0021] Step 101, detecting whether the network switching condition from the first network to the second network is met, wherein, when the first network is one of the IPV4 network and the IPV6 network, the second network is the other of the IPV4 network and the IPV6 network , the first network is used to connect to the first network card on the mobile node that supports the network protocol of the first network.

[0022] Step 102, if it is satisfied, connect the second network card in the idle state on the mobile node to the second network, where the second network card supports the network protocol of the second network.

[0023] Step 103, switch the mobile node...

Abstract

The invention discloses a method and system for switching between the IPV4 network and the IPV6 network. The method includes the steps of detecting whether the condition for switching from the first network to the second network is met or not, wherein the first network and the second network are different networks in the IPV4 network and the IPV6 network; if yes, enabling a second network card which is in the idle state on a mobile node to have access to the second network; switching the mobile node from a first network card to the second network card so that the mobile node can conduct communication through the second network. By means of the method and the system, without interrupting communication with a communication terminal does not need to be interrupted or conducting protocol conversion, heterogeneous network switching can be achieved, communication time delay can be reduced, and communication efficiency and communication quality can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a switching method and system between an IPV4 network and an IPV6 network. Background technique [0002] With the development of network technology and the expansion of network scale, IPV4 (the fourth version of Internet Protocol) can no longer meet the requirements of network development. The application of IPV6 (the sixth edition of the Internet Protocol Internet Protocol), which can provide a huge address space and has many new features that IPV4 does not have, is becoming more and more widespread. [0003] The wide application of IPV6 makes it inevitable for mobile nodes to switch between the IPV4 network and the IPV6 network. The current switching method is: when the mobile node accesses the network in the IPV4 network, the DNS server of the IPV4 network assigns the mobile node an IPV4 address, and establishes a home agent in the network to record the domain n...
