When, user terminal and network controller can also update tunnel context information respectively；So that network anchor point converges former network tunnel
Data and objective network tunnel data, and by the data after convergence respectively on former network tunnel and objective network tunnel point
Hair；With so that the user terminal converges the former data of network tunnel and the data in objective network tunnel, and by the number after convergence
Divide respectively on former network tunnel and objective network tunnel according to the application layer for being transmitted to user terminal, and by application layer data
Hair；Wherein, the former network tunnel is the data transmission tunnel that user terminal is communicated by former network with network anchor point.Namely
Say, if the success of objective network tunnel activation, user terminal and network anchor point can be in former tunnels and the tunnel newly activated（That is target
Network tunnel）Upper reception and transmission data；If otherwise objective network tunnel activation is unsuccessful, user terminal and network anchor point are still
Data are received and sent on former tunnel.
When need to remove user terminal with it is former it is internetwork eat dishes without rice or wine link connection when, the network controller is receiving use
After the former network tunnel that family terminal is sent deactivates request, feed back former network tunnel deactivation command to user terminal, so as to
Former network tunnel is deactivated completion signaling and sends the network controller to by objective network by family terminal；Network controller control
Make the network anchor point and perform former network tunnel dismantling operation.The deactivating operation that user terminal performs is to deactivate user terminal
The deactivating operation performed with the interface of former network, network anchor point（Also dismantling operation can be claimed）It is to deactivate（Remove）Network anchor point
With the interface of former network, the former network tunnel so far just completed between user terminal and network anchor point removes work, at this time user
