METHOD AND SERVICE DEVICE FOR PRIVATE CALL OF CONFERENCE IN IP MULTIMEDIA SUBSYSTEM

摘要

A method for a private call of a conference in an IP multimedia subsystem is disclosed. A service device receives a first request message which is transmitted by a first communication device and used for a private call with a second communication device; if the first communication device is a communication device at the presider side of the conference,the service device modifies the conference media of the communication devices which have attended the conference within the first communication device and the second communication device; after the modification of the conference media is completed, the service device establishes the private call between the first communication device and the second communication device. A service device for a private call of a conference in an IP multimedia subsystem is also disclosed correspondingly. In this invention, after the request for a private call is received, the conference media of the conference presider and/or the conference members is modified, which enables the conference presider/the conference members to make a private call conveniently according to their wishes and the actual situation with the conference members/the conference presider.
