ANONYMOUS COMMUNICATION METHOD

摘要

An anonymous communication establishment apparatus establishes a communication session between a first communication terminal and a second communication terminal if an anonymous level of the transmission originating end terminal designated in a communication connection request received from the first communication terminal is a permissible one for the communication from the first communication terminal to the second communication terminal. Thereafter, when having received, from the second communication terminal, a communication forwarding request in which the first communication terminal is designated as the transmission originating end terminal and further a third communication terminal is designated as a forwarding destination communication terminal, the anonymous communication establishment apparatus determines whether or not an anonymous level of the first communication terminal designated as the transmission originating end terminal in the communication forwarding request is a permissible one for the communication from the first communication terminal to the third communication terminal. If not, the anonymous communication establishment apparatus decides an anonymous level of the first communication terminal that is permissible for the communication from the first communication terminal to the third communication terminal, and uses the decided anonymous level to perform a forwarding control of communication session.
