Method and apparatus for stabilizing communication in mobile communication system

Abstract

A mobile communication system is provided including a plurality of base stations placed in a communication service area and connected to a network, wherein a mobile station communicates with a second station through the plurality of base stations and the network. The mobile communication system determines a virtual base station group, that is, an aggregation of the plurality of base stations communicating with the mobile station, based on a condition of a radio transmission path between the mobile station and each base station, and combines information received by the plurality of base stations that belong to the virtual base station group at a base station included in the virtual base station group, wherein the network connects the plurality of base stations non-hierarchically, wherein the base station transmits combined information to the second station through the network. In such a system, the base stations belonging to the virtual base station group are not limited to specific base stations when the mobile station moves in the communication service area. Accordingly, communication between a moving mobile station and the base stations is stabilized. Additionally, a single base station belonging to the virtual base station group executes processes related to communication between the mobile station and the second station. Accordingly, execution of such processes is not concentrated in a single communication node, even if the number of base stations placed in the communication service area increases.
