Communication management system, communication management method, and computer program product

摘要

A communication management system includes a storage unit, a receiving unit, and a first transmitting unit. The storage unit stores therein: an address of a first terminal that establishes a first session with a relaying apparatus; an address of a conversion system that establishes a second session with the relaying apparatus, the conversion system mutually converting a first communication scheme and a second communication scheme; information for identifying the second terminal that establishes a third session with the conversion system; and a host name of another communication management system managing an address of the second terminal. When the receiving unit receives, from the first terminal, a request to start communication between the first terminal and the second terminal, the first transmitting unit transmits, to the relaying apparatus, the address of the first terminal, the address of the conversion system, the terminal identifying information, and the host name.

主权项

1. A communication management system that manages communication terminals, the communication management system comprising:
a first memory configured to store therein:
address information indicating an address of a first communication terminal that establishes a first communication session with a relaying apparatus relaying communication data;address information indicating an address of a conversion system that establishes a second communication session with the relaying apparatus, the conversion system mutually converting a first communication scheme of communication data transmitted from the first communication terminal and a second communication scheme of communication data transmitted from a second communication terminal, the second communication scheme being used by the second communication terminal and being different from the first communication scheme used by the first communication terminal;terminal identifying information identifying the second communication terminal that establishes a third communication session with the conversion system; andhost name information indicating a host name of another communication management system managing address information indicating an address of the second communication terminal; a first receiver configured to receive, from the first communication terminal, start request information to start communication between the first communication terminal and the second communication terminal; and a first transmitter unit configured to transmit, to the relaying apparatus on the basis of the received start request information, the address information about the first communication terminal, the address information about the conversion system, the terminal identifying information, and the host name information that are stored in the first memory, wherein the another communication management system includes
a second memory configured to store the terminal indentifying information and the address information indicating the address of the second communication terminal indicated by the terminal indentifying information in association with each other;a second receiver configured to receive, from the conversion system, the terminal identifying information about the second communication terminal and the address information about the conversion system; anda second transmitter configured to transmit, to the second communication terminal, the received address information about the conversion system on the basis of the address information about the second communication terminal stored by the second memory in association with the received terminal identifying information, and the second transmitter is configured to transmit the address information about the second communication terminal to the conversion system on the basis of the received address information about the conversion system, the address information about the second communication terminal being stored by the second memory in association with the received terminal identifying information.
