Abstract: Disclosed are a D2D direct communication method and apparatus in a cloud base station system. The present invention includes receiving a measurement result, including information about D2D proximity or interference from other devices, from each of a first device and a second device, determining whether or not to admit D2D direct communication between the first device and the second device based on the measurement results, sending radio resource information to a second base station and receiving radio resource information of the second base station if it is determined that the D2D direct communication is admitted, negotiating radio resources, allocated for the D2D direct communication, with the second base station using the internal primitive, and allocating radio resources to the first device based on the negotiation.

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 of assigning a physical layer cell identity (PCI) to a femtocell base station. The method includes obtaining location information from a femtocell base station and storing the location information, a first step of determining whether a PCI does not collide and is not confused with PCIs of base stations present in an area having a radius of a first multiple of a the femtocell radius and a second step of determining whether a PCI does not collide and is not confused with PCIs of base stations present in an area having a radius of a second multiple of the femtocell radius when a PCI does not collide and is not confused with PCIs of base stations is not found in an area having a radius of a first multiple of the femtocell radius.
