ABSTRACT:
Disclosed here is a method for sending/receiving a message through a session control server disposed in each of hierarchical layers of a network system having a hierarchical structure. To achieve the above object, each of the session control servers is provided with operation mode confirming means for confirming a set operation mode and fixed destination solution means for setting an address so as to relay each received message to a specific address in accordance with the set operation mode. The session control server is also provided with location solution means for registering/managing a public address to be opened to external by a user and a user address given in the sub-domain to which the user belongs actually. Because a parent domain address can be used as an address to be opened to external for operating the session control server, the problems to occur due to a change of the user belonging sub-domain can be hidden from external and the parent domain can manage message traffics collectively.
