    摘要： A PUCI system is designed to process an incoming call originated by the user equipment toward the counterpart user equipment via an EMS node having a PUCI-light functionality, which includes an IBCF/I-CSCF, a S-CSCF, and a database storing the PUCI-light information. Through a query to the database indicating a suspicious session in relation to the incoming call, the IMS node immediately blocks the suspicious session or simply marks the suspicious session for the further processing at a subsequent node. The reason for rejection is included in a SIP BYE/ERROR message of an original session setup message, which is interpreted by a previous IMS node so as to obtain the relevant information from a SIP header. The relevant information is stored in either a global operator policy database or a local database, thus enabling a PUCI-negating IMS node to reject an unsolicited call related to the blocked session.

    摘要： To improve detection accuracy of SPIT, first, an identification information gathering apparatus receives various identification information from an IP phone terminal which has transmitted an INVITE message. A PUCI server generates bind identification information by binding or associating various identification information received from an identification information gathering apparatus via an SIP server and registers the bind identification information to a gray list stored in a list storing portion. A SPIT determination portion evaluates the bind identification information in reference to the gray list and determines whether or not the session start request from the IP phone terminal is allowed.

    摘要： A communication system shares terminal identification information (TII) used for identifying a terminal that sends a spam phone call, with another communication system belonging to another network provider, and includes: a storage section that stores the TII of a terminal that sends a spam phone call; a transmission section that transmits the TII stored in the storage section to the other communication system; a reception section that receives the TII used for identifying the terminal that sends the spam phone call; a registration section that registers the TII received by the reception section in the storage section; and a spam phone call determination section that determines whether there is a match between terminal information indicating information of an outgoing call terminal that sends a connection request, and the TII stored in the storage section, thereby determining whether the outgoing call terminal sends a spam phone call.
