ABSTRACT:
In a radio access network, novel systems and methods reduce processing delay, and improve integration with IP networks, by separating user data from connection management and control data at a Node B or at a base station. The user data are routed to an IP (Internet Protocol) switch, whereas the connection management and control data are routed to a centralized radio network controller (RNC). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handing all connection management and control data for a plurality of Node B's, thereby simplifying the switching of user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP switch is equipped to switch user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data.
