Abstract

An audio communication bandwidth management system comprises a communication connection server and two or more network apparatuses connected to each other via two or more connections on a network. When there is a change in a usage state of one of the connections connected to other network apparatuses, the network apparatus recalculates bandwidth data for network areas based on the changed usage state and transmits the recalculated bandwidth data to a communication connection server. The communication connection server references corresponding bandwidth data stored in a database upon receiving an audio communication line request, and then determines whether or not normal communication is enabled by comparing the bandwidth data with a required bandwidth calculated based on the audio communication line request. Then, the server determines whether or not a line should be permitted based on the determination results, transmits judgment results to a terminal, and then updates the database in accordance with the bandwidth data received from the network apparatus. According to the system, bandwidth data for audio communication is transmitted to a communication connection server by a network apparatus for performing communication between network areas. With this arrangement, even when there is a change in a usage state of any one of the connections, the number of audio communication calls between terminals is managed appropriately.
