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.
