Radio communication system, terminal equipment used therefor and service control station used therefor
First Claim
1. A radio communication system comprising:
- (a) a plurality of terminal equipment connected to one another by a radio system through a radio base station connected to a communication line; and
(b) a service control station existing on said communication line and controlling communication among said plurality of terminal equipment, said plurality of terminal equipment being capable of communicating data information with one another through said service control station, said service control station receiving data information and index information acting as an index of said data information from a transmitter terminal equipment, forwarding the index information to a receiver terminal equipment upon receipt of the data information and the index information, and transmitting the data information to the receiver terminal equipment upon request from the receiver terminal equipment.

Abstract
There is provided a radio communication system including (a) a plurality of terminal equipments connected to one another by a radio system through a radio base station connected to a communication line, and (b) a service control station existing on the communication line, and controlling communication among the terminal equipments, the terminal equipments being designed to be capable of communicating data information with one another through the service control station. For instance, the data information includes picture data, image data, and audio data. For instance, each of the terminal equipments is comprised of a simplified personal handyphone. In accordance with the radio communication system, a terminal equipment or a PHS terminal equipment stores only minimum index information in an internal storage circuit, and hence, it is no longer necessary to store data information. This is realized by a small-sized storage circuit.
