Abstract

PURPOSE:To make the communication of the entire storage exchange network smooth, by rejecting the reception of the message addressed to the terminals contained in the station itself and receiving only the message addressed to the terminals contained in other stations, if the rate of use of a storage device of a relay exchange station is a prescribed value or more. CONSTITUTION:When a storage exchange station A is a relay exchange station, a storage exchanger 1c makes transmission request REQ-A relating to a message MES- A to a storage exchanger 1a. The storage exchanger 1c analyzes the address and when it recognizes that the address is for a terminal 3a contained in the station itself, the rate of use is checked for a storage device 2a, and if the rate of use is a prescribed value (80-90%) or more, a transmission-disabled-signal NCK is returned to a storage exchanger 1c. When the exchanger 1c makes a transmission request REQ-B of a message MES-B, the exchanger 1a identifies the address which is for the terminals contained in other stations, and returns a transmission enable signal ACK 1.
