Abstract
In a telecommunication system a service area is divided into a plurality of cells. Radio base stations are disposed corresponding to individual cells of the plurality of cells. Each radio base station stores regional information such as disaster information, advertisement information, and shopping information. When a communication is made between a radio base station and a portable telephone terminal, regional information such as disaster information, advertisement information, and shopping information is transmitted from the base station to the portable telephone terminal.
