Abstract: The present invention relates to a method of selecting, by an eNB, a PCC for UE in a multiple component carrier system. The method includes obtaining mobility state information about the UE and coverage information and load information about carriers managed by the eNB; determining whether or not a mobility state value of the UE is greater than a specific threshold based on the obtained mobility state information; and selecting the PCC based on the load information if, as a result of the determination, the mobility state value is greater than the specific threshold. In accordance with the present invention, a BS adaptively selects a PCC by taking the load state of a carrier (or cell), UE mobility velocity, and the coverage of each carrier (or cell) into consideration.

Abstract: A Transport Network Layer (TNL) connection setup method for a base station includes monitoring Physical Cell Identity (PCI) values of neighboring cells. When it is monitored that the PCI values are changed, IP addresses of neighboring base stations corresponding to the changed PCI values are acquired. Thereafter, it is determined whether it is necessary to perform a new TNL connection setup with respect to other neighboring base stations, based on the changed PCI values and the acquired IP addresses. When it is determined that it is necessary to perform the new TNL connection setup, the TNL connection setup is performed with the acquired IP addresses.
