Abstract
The present invention relates to a service system for interconnection between different kinds of communication terminals and to a communication node device and a communication terminal used in the same. The object of the invention is to offer versatility and to need no operation for media conversion by an originating party. An information factor indicating a communication terminal attribute is inserted in a message to establish a call between a communication terminal and a communication node device. In the communication node device, when a communication refusal from a destination communication terminal due to a communication terminal attribute disagreement is recognized in response to a destination message sent from the originating communication terminal to the destination communication terminal, a medium receivable by the destination communication terminal is selected and the destination message from the originating communication terminal is corrected. The corrected message is forwarded to the destination communication terminal. Then when communication is established, the media converting means notifies the destination communication terminal of the destination call from the originating communication terminal, while it notifies the originating communication terminal of a communication establishment through the media conversion.
