Claim:
1. A communication management system configured to manage a plurality of communication terminals communicating in a same communication session, the system comprising: a receiver to receive, from a first communication terminal, a group creation request for creating, while maintaining the same communication session, a first group with a second communication terminal, the group creation request including first terminal identification information identifying the first communication terminal and second terminal identification information identifying the second communication terminal, the first communication terminal and the second communication terminal each being one of the plurality of communication terminals communicating in the same communication session; circuitry to generate first group identification information identifying the first group and store group information in a memory, the group information associating the first group identification information with the first terminal identification information and the second terminal identification information; and a transmitter to transmit the group information to each of respective ones of the plurality of communication terminals communicating in the same communication session, wherein the receiver further receives, from the first communication terminal, a group change request for changing a group to which the first communication terminal belongs from the first group to a second group, the circuitry updates the group information in the memory so as to change the first group identification information associated with the first terminal identification information to second group identification information identifying the second group, and the transmitter transmits the updated group information, including the second group identification information and identifiers of all communication terminals in the second group, to each of respective ones of the plurality of communication terminals communicating in the same communication session.
