Today, two major trends in networking can be observed. First, now that mobile telephony is a fact, also Internet connec-tivity is moving towards mobile access. Second, real time applications, requiring QoS, are offered to Internet users. This paper will propose a mechanism for the Internet to accommodate both trends. MPLS will be used to set up mobile connections between communicating nodes. With DiffServ on MPLS, QoS can easily be guaranteed. Using hierarchy, the loss of quality upon hand-off can be reduced, data and signalling traffic can be cut and mobility can be made transparent to the end users.
