Abstract: 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.

Abstract: Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

Abstract: The present invention relates to a method and apparatus for managing radio resources in a multi-carrier and heterogeneous network-integrated radio access environment. A method of managing radio resources in a BS supporting multiple carriers includes sending an RRC connection reconfiguration message, including measurement control information, to UE, receiving a measurement report, including a measurement result for an HetNet RAT cell, from the UE, determining to configure HetNet RAT bearer connection with the UE based on the measurement report, sending an RRC connection reconfiguration message, requesting to configure the HetNet RAT bearer connection, to the UE, and sending some of or the entire traffic for the UE, to the UE through the HetNet RAT bearer. If overload or interference occurs in a serving cell, some of or the entire traffic is transmitted through a cell based on HetNet RAT, if necessary. Accordingly, load balancing or interference coordination can be achieved.
