RADIO ACCESS NETWORK CONTROL METHOD AND RADIO ACCESS NETWORK

摘要

In radio access network (RAN) 1 of the present invention, the configuration of radio network controller (RNC) 4 is physically separated into control plane controllers (CPE) 41a-41b for controlling signalling and user plane controllers (UPE) 42a-42c for controlling user data. User plane controllers 42a-42c report their own status information (traffic information/used channel bandwidth information/alarm information) to control plane controllers to which they belong, and control plane controllers 41a-41b manage the status information of the user plane controllers for each of user plane controllers subordinate thereto.

1. A method of controlling a radio network controller of a radio access network, wherein the radio network controller comprises a plurality of control plane controllers and a plurality of user plane controllers, the method comprising:
implementing the plurality of user control plane controllers separate from said plurality of control plane controllers; logically subordinating each user plane controller to only one control plane controller; effecting transfer of status information between a user plane controller and a control plane controller other than the control plane controller to which the user plane controller is logically subordinate notwithstanding that the user plane controller is logically subordinate to another of said control plane controllers.
