  • Publication number: 20200329349
    Abstract: An apparatus performs transmission and reception of messages via which a plurality of services coordinate with each other in a message control system. The apparatus integrates a plurality of messages into a first message, based on relationships between message transmission and message reception caused by the plurality of services, and transmits the first message to another information processing device in the message control system. The apparatus receives a second message integrated by another information processing device, and decompose the received second message into messages including a third message. The apparatus further integrates the decomposed third message and a fourth message into a fifth message, and transfers the integrated fifth message to another information processing device.
