COMMUNICATION SYSTEM USING MULTIPLE TYPES OF COMMUNICATION MODES, COMMUNICATION TERMINAL, COMPUTER PROGRAM, AND COMMUNICATION METHOD
First Claim
1. A communication system comprising:
- multiple communication terminals that are used by multiple users; and
a management unit that holds management information expressing which type of communication mode corresponding to which communication address information is used by which user and by which communication terminal, and connection information including communication address information of one communication terminal that has communicated and communication address information of the other communication terminal that has communicated,wherein the management unit holds connection information corresponding to an instance of communication even if that instance of communication has ended;
each communication terminal communicates with other communication terminals in one or more types of communication modes, and includes a communication support unit;
in the case where a first-type communication mode of a first communication terminal that includes the communication support unit is used by a first user, the communication support unit accesses the management unit to specify communication address information corresponding to the first-type communication mode in a second communication terminal used by a second user, and the first communication terminal communicates with the second communication terminal in the first-type communication mode using the specified communication address information;
the first user is a user that used a second-type communication mode prior to using the first-type communication mode of the first communication terminal;
the second user is a user that communicated with the first user using the second-type communication mode prior to using the first-type communication mode of the first communication terminal; and
the specified communication address information is communication address information specified based on an instance of communication address information within the connection information that has another instance of communication address information corresponding to the second-type communication mode used by the first user, and based on the management information.

Abstract
A communication system includes multiple communication terminals that are used by multiple users; and a management unit that holds management information expressing which type of communication mode corresponding to which communication address information is used by which user and by which communication terminal, and connection information including communication address information of one communication terminal that has communicated and communication address information of the other communication terminal that has communicated. The management unit holds connection information corresponding to an instance of communication even if that instance of communication has ended. Each communication terminal can communicate with other communication terminals in one or more types of communication modes, and includes a communication support unit. In the case where a first-type communication mode of a first communication terminal that includes the communication support unit is used by a first user, the communication support unit accesses the management unit to specify communication address information corresponding to the first-type communication mode in a second communication terminal used by a second user, and the first communication terminal communicates with the second communication terminal in the first-type communication mode using the specified communication address information. The first user is a user that used a second-type communication mode prior to using the first-type communication mode of the first communication terminal. The second user is a user that communicated with the first user using the second-type communication mode prior to using the first-type communication mode of the first communication terminal. The specified communication address information is communication address information specified based on an instance of communication address information within the connection information that has another instance of communication address information corresponding to the second-type communication mode used by the first user, and based on the management information.

5. A communication terminal capable of communicating with other communication terminals in one or more types of communication modes, the communication terminal comprising:
-
a communication support unit that, in the case where a first-type communication mode of that communication terminal is used by a first user, accesses a management unit to specify communication address information corresponding to the first-type communication mode of a second communication terminal used by a second user, wherein the communication terminal communicates with the second communication terminal in the first-type communication mode using the specified communication address information; the first user is a user that used a second-type communication mode prior to using the first-type communication mode of the first communication terminal; the second user is a user that communicated with the first user using the second-type communication mode prior to using the first-type communication mode of the first communication terminal; and the management unit is a unit that holds management information expressing which type of communication mode corresponding to which communication address information is used by which user and by which communication terminal, and connection information including communication address information of one communication terminal that has communicated and communication address information of the other communication terminal. - View Dependent Claims (6)

7. A communication method in which a first communication terminal used by a first user or another communication terminal:
-
communicating with a second communication terminal used by a second user or another communication terminal in a second-type communication mode; and transmitting connection information including communication address information in the second-type communication mode of the first communication terminal or other communication terminal and communication address information in the second-type communication mode of the second communication terminal or other communication terminal to a management unit that holds management information expressing which type of communication mode corresponding to which communication address information is used by which user and by which communication terminal, the management unit managing the connection information; the first communication terminal accessing the management unit to specify communication address information corresponding to a first-type communication mode of the second communication terminal used by the second user in the case where the first-type communication mode of the first communication terminal is used by the first user; specifying communication address information based on an instance of communication address information within the connection information that has another instance of communication address information corresponding to the second-type communication mode used by the first user, and based on the management information; and communicating with the second communication terminal in the first-type communication mode using the specified communication address information.
