Patent ID: 7616958

Claim:
A method of setting cell information to set cell information in a radio access network provided with a radio network controller accommodating at least one radio base station, said radio network controller being physically divided into a control-plane processing device and at least one user-plane processing device, wherein said control-plane processing device performs the control plane process, and said user-plane processing device performs the user plane process under control of said control-plane processing device, comprising: a first step of holding in advance at least one item of cell information in said control-plane processing device, said cell information being the information to be held in common with said user-plane processing device that is under control of said control-plane processing device, a second step of requesting said cell information from said user-plane processing device to said control-plane processing device, and a third step of notifying said cell information to be held in common in both of said control-plane processing device and said user-plane processing device from said control-plane processing device to said user-plane processing device that has requested said cell information.
