- the anonymous level Y specified by the communication terminal 110-1 as the originating terminal is not regulated by the anonymous level regulation condition applied between the communication terminal 110-1 and the communication terminal 110-3 as the transfer destination. Therefore, if there is no other failure, a communication session is established between the communication terminal 110-1 and the communication terminal 110-3 (FIG. 6 (23)). Thereafter, the communication session between the communication terminal 110-1 and the communication terminal 110-2 and the communication session between the communication terminal 110-2 and the communication terminal 110-3 are discarded, and the communication terminal 110-1 and the communication terminal Only the communication session with 110-3 remains.
- the communication transfer request transmitted from the transfer source communication terminal 110-2 is directly transmitted to the communication terminal 110-1 of the originating terminal through the communication establishment unit 131 of the anonymous communication establishment device 130.
- the communication terminal 110-1 transmits a communication connection request to the transfer destination communication terminal 110-3 using the same anonymous level X as that of the communication terminal 110-2.
- the communication terminal 110-3 sets an anonymous level restriction condition that does not allow connection at the anonymous level X, the transfer fails.
