Abstract

Communication system in which a sending, a receiving and a location registration can be performed even when congestion occurs in S-CSCF. The communication system based on an IP multimedia subsystem architecture includes a plurality of call session control apparatuses. The plurality of call session control apparatuses have the function for judging whether congestion occurs or not and the function for transmitting a congestion notification message that indicates the occurrence of the congestion to an adjacent apparatus when it is judged that the congestion occurs.
