CENTRALIZED RADIO NETWORK CONTROLLER |
摘要 |
In a radio access network (300), novel system and methods reduce processing delay, and inprove integration with IP networks, by separating user data (325) from connection management and control data (329) at a node B (310) or at a base station. The user data are (325) routed to an IP(Internet Protocol) switch (309), whereas the connection management and control data (329) are routed to a centralized radio network controller (RNC) (303). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handling all the connection management and control data for a plurality of the nodes B's, thereby simplifying the switching of the user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP swicth is equipped to swicth user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data. |
