Embodiment Construction

[0018] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. For this reason, the given embodiments may have different forms and should not be construed as limiting the descriptions set forth herein. Accordingly, the embodiments are described below, by referring to the figures, only for explaining aspects of the present description.

[0019] Figure 1A and Figure 1B is a diagram showing a cellular network environment. refer to Figure 1A and Figure 1B , the circle around each base station marked with ■ indicates the cell coverage of the base station, and the user terminals marked with △ are distributed within the cell coverage of each base station. The cell coverage refers to the service area where each base station can provide communication services. To this end, each base station may provide data transmission to user terminals within its cel...

Abstract

A method of determining whether to switch off a base station's own power in the base station within a cellular network may comprise: receiving terminal messages having real number values from terminals within cell coverage of the base station; calculating real number values of base-station messages individually regarding the terminals based on the received terminal messages; transmitting the base-station messages having the calculated real number values individually to the terminals; repeatedly performing the receiving, the calculating, and the transmitting until the calculated real number values of the base-station messages are converged to constant values; when the real number values of the base-station messages are converged, calculating a base-station message convergence value, which is one real number value regarding the terminals, based on the converged real number values of the terminal messages; and / or determining whether to switch off the base station's own power based on the base-station message convergence value.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2013-30576 filed in the Korean Intellectual Property Office on March 21, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a method of cutting off power of a base station within a cellular network by using message passing, and a base station and a cellular network system using the method. Background technique [0004] Currently, with the growth of mobile terminals such as laptop computers, personal digital assistants (PDAs), and smart phones, communication services are greatly increasing. In order to satisfy the increased communication traffic, the requested communication traffic is handled by installing base stations to overlap each other in areas where the communication traffic is concentrated. [0005] However, the amount of requested communication traff...
