Publication number: 20140162603Abstract: A method of managing a service mode of a femto cell base-station and access allowance for a terminal is disclosed. The method of managing access allowance includes receiving a first access allowance change request for a terminal, and transmitting a second access allowance change request for the terminal to a mobility management entity (MME) in response to the first access allowance change request. With the method of the example embodiments of the present invention, the service mode of the femto base-station and the access allowed terminal can be changed in real time according to a situation of the user. Accordingly, quality of service can be improved and efficient management of the femto base-station can be achieved through interference control between the macro base-station and the femto base-station.Type: ApplicationFiled: August 19, 2013Publication date: June 12, 2014Applicant: Electronics and Telecommunications Research InstituteInventors: Eun Seon CHO, Chan Yong LEE, Hyeon Ju OH, Byung Han RYU, Nam Hoon PARK
