Step 312：Infrastructure equipment is known as interface z9, Ran Houcha from the interface of oneself to response message, by the interface
See convergence table, select all title thresholdings to be equal to the convergence list item of the title thresholding of the response message, for the remittance of each selection
Poly- list item, infrastructure equipment perform operations described below：If the data block ID set of the convergence list item disappears with the response received
The data block ID intersection of sets collection S2 of breath is not sky, then infrastructure equipment builds a response message, which disappears
It is 1 to cease form, and title thresholding is the title thresholding of the convergence list item, and data block ID collection is combined into the data block ID collection of the convergence list item
The data block ID intersection of sets collection S2 for the response message for closing and receiving, type of message 3, loads to be each in intersection S2
The data block set that data block ID is defined, then sends the response message of structure, infrastructure from the interface domain of the convergence list item
Equipment deletes intersection S2 from the data block ID set of the convergence list item at the same time, if the data block ID collection of the convergence list item is combined into
Sky, then delete the convergence list item, performs step 311；
Step 313：From interface z8 receive response message mobile node U1 check required list and delete title thresholding be equal to should
Title thresholding and data block the ID set of response message are equal to the request list item that the data block ID of the response message gathers, if moved
It is equal to the request list item of the title thresholding of the response message in the required list of dynamic node U1 there is no title thresholding, then performs step
314, otherwise perform step 311；
Step 314：All data blocks received are built into data C2 by mobile node U1；
Step 315：Terminate；
In step 310, if the mobile node that the request message is received from interface z6 is capable of providing data C2, and the movable joint
Interface z6's point fails before sending the response message, which then selects an interface x3 for being in effective working status,
A response message is built, the response message is sent from interface x3, step 311-315 is performed and completes to obtain data procedures.
4. a kind of new generation network implementation method based on multipath according to claim 3, it is characterised in that in movement
Node U1 has N number of interface, interface f supported protocols pfAnd with the supported protocol p of infrastructure equipment I2fInterface link be connected, 1
Under conditions of≤f≤N, if mobile node U1 detects that interface f1 fails, 1≤f1≤N, then perform following handoff procedures：
Step 401：Start；
Step 402：Mobile node U1 checks required list, all request list items for selecting interface thresholding to be equal to interface f1, for every
A request list item, mobile node U1 perform operations described below：Mobile node U1 selects eligible 3 interface f2, by the required list
The interface thresholding of item is updated to interface f2, builds a handover request, the message format of the handover request is 0, and entitled sky, disappears
It is 4 to cease type, loads as the request list item, then sends the request message from interface f2；
Condition 3：In the total interface of mobile node U1, the request list item number of the set of interfaces thresholding comprising interface f2 is most
It is small；
Step 403：Infrastructure equipment I2 checks convergence table after interface f3 receives handover request, select title thresholding and
Data block ID set thresholdings are equal to the title thresholding and data block ID set of the request list item in the handover request load received
Convergence list item, the interface thresholding of the convergence list item is then updated to interface f3；
Step 404：Terminate.
