Abstract
A cellular asynchronous transfer mode packet network and a method for transferring packet data in the same is disclosed. A virtual circuit is established between a serving radio network controller and a target radio network controller, or between the serving radio network controller and a target packet data node. Also, individual packet paths are established between the serving radio network controller and the target radio network controller or between the serving radio network controller and the target packet data node through a mobile packet router. Individual data blocks of the packet data or packet sessions are multiplexed/demultiplexed over the virtual circuit on the basis of a service specific convergence sub-layer protocol. The multiplexed/demultiplexed data blocks are routed according to authenticated destination identifiers. Therefore, one virtual circuit is established between a packet network access node and a radio network controller and packet data or packet sessions from a plurality of mobile terminals are multiplexed/demultiplexed and transferred on the established virtual circuit.
