Abstract: The present invention relates to an energy saving method and a centralized control device for receiving load information and SRS (Sounding Reference Signal) information of a cell from a base station, identifying whether an energy saving trigger condition is satisfied by using the received load information, identifying whether an energy saving condition is satisfied by using the received SRS information if the energy saving trigger condition is satisfied, and transmitting a transmission power management request message to the base station if the energy saving condition is satisfied. Further, the present invention provides a base station and a transmission power management method for the base station which manages a transmission power of a cell corresponding to a transmission power management request message received from the centralized control device.

Abstract: A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).

Abstract: A mobile communication system and method for managing the base station identifiers is provided. The method includes transmitting macro base station information from a terminal to a first pico base station; transmitting a Neighbor Relation Table (NRT) including the macro base station information from the first pico base station to a Self Organizing Network (SON) server; determining, at the SON server, whether a second pico base station using same Physical Cell Identifier (PCI) as the first pico base station exists by comparing a previously stored NRT with the received NRT; and reallocating, at the SON server, upon determining that the second pico base station uses the same PCI as the first pico base station, new PCIs to the first and second pico base stations.
