Embodiment Construction

[0110] The communication system (100) is designed according to the construction method of the Universal Mobile Telecommunications System (UMTS) described in the 3rd Generation Partnership Project (3GPP: 3rdGeneration Partnership Project), and its main component is IMS (please refer to reference [ 8]).

[0111] The communication terminal (101) is connected to an IMS (111) via an ingress network (102).

[0112] The ingress network (102) can be a mobile wireless communication network designed according to the Universal Mobile Communication System (UMTS) standard, that is, a Universal Terrestrial Access network (Universal Terrestrial Access network). This network can pass through a data packet The transmission network domain (Packet-Switshed-Domain) finds the entrance of the communication terminal equipment to the IMS (111); the entrance network (102) can also be a kind of entrance network designed according to the Global System for Mobile Communications (GSM) standard, that is, a...

Abstract

The invention relates to a communication system, communication terminal device, conference control unit, communication system control method, communication terminal device control method and conference control unit control method. A communication system having a conference server and a conference control unit to which a call control protocol message is transmitted which specifies whether a communication terminal needs to be added to a conference, and / or a conference needs to be created, and / or a conference needs to be terminated, and / or information about at least one of the conferences provided by the conference server needs to be transmitted to a communication terminal.

Description

technical field [0001] The invention relates to a communication system, communication terminal equipment, a conference control unit, a communication system control method, a communication terminal equipment control method and a conference control unit control method. Background technique [0002] The 3rd Generation Partnership Project (3GPP: 3rd Generation Partnership Project) has developed a standard for the construction method of the so-called Internet Protocol Multimedia Core Network Subsystem (IMS: Internet-Protokoll-Multimedia-Core network-Subsystem). [0003] IMS (that is, the IMS standard developed by 3GPP according to the requirements of communication networks) can provide various communication services for mobile communication terminal equipment based on the Internet communication protocol (IP). [0004] These communication services include Voice-over-Internet-Protocol (VoIP: Voice-over-Internet-Protocol), video telephony, and video conferencing, such as teleconfere...
