Abstract:
1. A mobile communication system which includes a mobile unit, a radio base station, and a radio controller, wherein the radio controller comprises: first and second user plane processing means for performing processing to control transfer of user data in relation to the mobile unit; and control plane processing means for processing to control transfer of signaling having a control signal, the control plane processing means being physically separated from the first and second user plane processing means, and when detecting a congestion state of processing, the first user plane processing means transfers a first part of the processing to the second user plane processing means while maintaining a second part of the processing at the first user plane processing means, wherein said first user plane processing means comprises: wherein said APL unit comprises: a control unit for controlling said lower protocol management part, said congestion detection part, and said congestion state control part; and a bus that communicatively connects said lower protocol management part, said congestion detection part, and said congestion state control part.
