Communication system

Abstract

A communication system adopts communication means having a small effective communication range for communication between mobile terminals and a server functioning as a cell station, so that each server is responsible for a small range only. In this manner, the communication system produces information about how servers are distributed on the network based on the geographic location of each server, thereby pre-delivering the information about such geographic locations and estimating how much and when data is to be delivered based on the positional relationship between servers and mobile terminals for load sharing.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a communication system which operates under a multi-access environment where a plurality of mobile terminals simultaneously communicate with a single cell station. In particular, the present invention relates to a communication system which can overcome the problem of a cell station becoming overloaded as the number of such mobile terminals increases. [0003] More specifically, the present invention relates to a communication system which can overcome the problem of it becoming more difficult to efficiently layout cell stations in the service area and to successfully carry out routing as cells become smaller. More particularly, the present invention relates to a communication system which allows the network of installed cell stations to be dynamically reconfigured according to their respective locations.

Benefits of technology

The present invention provides a communication system that can handle a large number of mobile terminals simultaneously communicating with a single cell station without becoming overloaded. The system uses connection servers as cell stations, each responsible for a small range of mobile terminals, and produces information about neighboring connection servers based on their geographic location. The system also allows for dynamic reconfiguration of the network of installed cell stations based on their respective locations. The communication system uses small effective communication ranges for communication between mobile terminals and a cell station, and pre-delivers information about how connection servers are distributed on the network for load sharing. The system also allows for the installation of new movable connection servers and monitors the processing capability of each connection server for load sharing. Overall, the communication system provides superior performance and flexibility for communication in a multi-access environment.

Problems solved by technology

Thus, as the number of terminals increases, the same cell station has more terminals connected thereto; that is, the cell station is easily overloaded.

The heavy load described above poses a problem in that the data transfer rate becomes low.

In order to overcome this problem, smaller cells are usually used; however, smaller cells make it difficult to efficiently layout the cell stations in the service space and successfully carry out routing as the number of cell stations increases.
