<P>PROBLEM TO BE SOLVED: To provide a communication terminal, a communication system, a communication method and a communication program that can reliably disconnect sessions between communication terminals establishing P2P communication. <P>SOLUTION: When receiving a first request signal from a management terminal managing session establishment states out of the other communication terminals with established sessions, the communication terminal transmits second request signals requesting session disconnection to the communication terminals other than the management terminal (S53). When receiving first response signals from the other communication terminals to which the second request signals have been transmitted (S55: YES), the communication terminal disconnects the sessions with the other terminal apparatuses that have transmitted the first response signals (S59). When disconnecting the sessions with all the communication terminals other than the management terminal, the communication terminal transmits a second response signal to the management terminal (S61) and disconnects the session with the management terminal (S63). <P>COPYRIGHT: (C)2012,JPO&INPIT |
