Telecommunication system, radio base station thereof, and portable telecommunication terminal thereof

摘要

A service area is divided into a plurality of cells. Radio base stations are disposed corresponding to individual 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.
