Access network for transmiting data packets between a network and a terminal via a radio communication system, and method for operating the same

摘要

The invention relates to an access network for transmitting data packets between a network (NW) and a terminal (UE) via a radio communication system, and to a method for operating the same. The access network (AN) comprises a number of nodes (UPS) that are each linked with at least one radio station of the radio communication network and that are adapted to convert data stemming from the network (NW) to a format that is compatible with the transmission in the radio communication system. A permanent first address is defined for the terminal (UE). Data packets that are directed to the first address are forwarded to the address of a processor (VMH) allocated to the terminal (UE), said processor emulating the terminal (UE) in the access network and tracing its movement. The processor behaves towards the network (NW) as a mobile terminal that is compatible with a mobility protocol (Mobile IP, Cellular IP, IPv6).
