20110141972 | TNL CONNECTION SETUP METHOD AND APPARATUS FOR BASE STATION USING DOWNLINK RECEIVER - 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. | 06-16-2011 |
