Problems solved by technology

[0004] The current e-mail service has a social problem that e-mails (messages) called spam are unilaterally sent by the sender to the recipient, although the recipient does not intend to receive the mail
This problem may be caused by the dramatic reduction in communication costs that comes with the spread of the Internet, or by the possibility of sending large volumes of e-mail from network access terminals such as readily available personal computers

Embodiment Construction

[0039] figure 1 is a block diagram showing the structure of an IMS network as an embodiment of the present invention.

[0040] the above figure 1 It is a schematic diagram of an IMS network using PUCI. Before describing the structure shown that solves the target problem examined by PUCI, the concept of operation of PUCI will be briefly explained below.

[0041] The leftmost O-UE indicates the calling terminal (ie, the originating UE), and the rightmost T-UE indicates the called terminal (ie, the terminating UE).

[0042] When the O-UE makes a call, a SIP INVITE message is sent for the SIP-URI (Session Initiation Protocol-Universal Resource Identifier) ​​of the T-UE. The message is relayed in routing by the IMS of the mobile communication network on the calling side called O-PLMN (Public Land Mobile Network) and received by the mobile communication network on the called side called T-PLMN.

[0043] In the IMS network system, communication is performed using the SIP protocol...

Abstract

Provided is a communication system which provides a multimedia service which can request a communication network to release registration of a transmission terminal which has been registered as an unauthorized terminal in the network. Typically, when the transmission terminal is connected to a transmission side network and registered as an unauthorized terminal in the arrival side communication network, the transmission side network requests the arrival side communication network to release the registration. It is also possible to report to the transmission terminal, that the arrival of the communication in the communication system is limited.

Description

technical field [0001] The present invention relates to a communication system and a communication control method on which multimedia services including voice services on an IP network are based. [0002] Priority is claimed from Japanese Patent Application No. 2008-259419 filed on October 6, 2008 and Japanese Patent Application No. 2008-329149 filed on December 25, 2008, the contents of which are incorporated herein by reference. Background technique [0003] According to the recent trend of using IP (Internet Protocol), attempts have been made to use a system using IP for a voice communication system generally using a telephone network. A mobile communication standardization organization called "3GPP" (Third Generation Partnership Project) has carried out standardization of IMS (Internet Multimedia Subsystem) as a basis for multimedia services including voice services over IP networks. In recent years, static or fixed IP systems known as "NGN" (Next Generation Networks) h...
