A METHOD AND SYSTEM FOR IMPLEMENTING A MOBILE VIRTUAL PRIVATE NETWORK

摘要

A method for implementing a mobile virtual private network, includes that a first mobile user device sends routing information to a second provider edge device through a first provider edge device (s101); a second mobile user device obtains the routing information through the second provider edge device (s102); a mobile sub-network, which the second mobile user device belongs to, communicates data with the first mobile user device through a third provider edge device (s105), according to a new label of the second mobile user device which is queried (s103); or when a new label is not existed, the second mobile user device communicates data with the first mobile user device through the second provider edge device (s104). A mobile virtual private network system can be implemented. A solution to support the mobility of BGP/MPLS VPN, in which the MPLS bone network and the mobile sub-network are combined organically, solves the shortness problem of non-supporting the mobility of virtual private network in the prior art.
