Second network；
The second internet protocol address of second network interface card and the movable joint are sent to the name server of second network
The domain name of point, and establish reflecting between the domain name of the mobile node and second internet protocol address in domain name server
Penetrate；
To the first network that first network interface card is sent for connecting the Interworking gateway of the first network and second network
Second internet protocol address of protocol address and second network interface card, in the Interworking gateway with establishing the first network agreement
Mapping between location and second internet protocol address.
6. a kind of IPV4 networks using described in claim 1-5 any one claims and the internetwork switching methods of IPV6
IPV4 networks and the internetwork switching systems of IPV6, it is characterised in that including：
Detection module, for detecting whether meet the network switching condition from first network to the second network, wherein, described first
When network is one in IPV4 networks and IPV6 networks, second network is IPV4 networks and another in IPV6 networks, institute
The first network interface card that first network is stated for the procotol with supporting the first network on mobile node is connected；
Communication module, for when meeting the network switching condition, the second of idle state being on the mobile node
Network interface card accesses second network, wherein, second network interface card supports the procotol of second network；
Handover module, for the mobile node to be switched into second network interface card from first network interface card, make the movable joint
Point is communicated by second network.
7. IPV4 networks according to claim 6 and the internetwork switching systems of IPV6, it is characterised in that the detection mould
Block is additionally operable to receive the signal intensity of second network, and the signal intensity and signal threshold value, strong in the signal
Degree judges network switching condition of the satisfaction from first network to the second network when being higher than the signal threshold value, wherein, the signal
Intensity is the signal intensity of the access point of second network of second network interface card detection.
8. IPV4 networks according to claim 6 and the internetwork switching systems of IPV6, it is characterised in that the communication mould
Block is additionally operable to：
Access request is sent to the access point of second network by second network interface card, by described in second network interface card access
Second network；
The second internet protocol address of second network interface card and the movable joint are sent to the name server of second network
The domain name of point, and establish reflecting between the domain name of the mobile node and second internet protocol address in domain name server
Penetrate；
To the first network that first network interface card is sent for connecting the Interworking gateway of the first network and second network
Second internet protocol address of protocol address and second network interface card, in the Interworking gateway with establishing the first network agreement
Mapping between location and second internet protocol address.
