IMS Conference Media Modification for Private Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IP multimedia subsystem (IMS) conferences, conference presiders cannot make private calls with specific members without disrupting the rest of the conference, lacking the ability to prompt or receive support from certain members.
Innovation Solution
A method and service device that modifies conference media to establish a private call between a conference presider and a member, allowing for private communication without affecting other participants, by receiving and processing request messages to shield or unshield communication paths as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conference presider makes a private call with a certain conference member, then private communication between presider and member is enabled, but the conference for other members is interrupted or affected
Solution Approach 1:
The communication stream is segmented into multiple independent paths: the conference call continues on one path while the private call is established on a separate path. The service device creates parallel communication channels, allowing the presider to engage in private conversation with one member while maintaining the conference connection with all other members simultaneously.
Solution Approach 2:
The private call is nested within the ongoing conference call structure. The service device embeds the private communication channel inside the conference framework, where the presider can switch between conference and private modes without completely disconnecting from either, similar to nested dolls where one structure contains another.
2Adaptability or versatility
If a conference presider maintains continuous participation in the conference, then conference management capability is preserved, but the ability to have private conversations with members is lost
Solution Approach 1:
The communication mode is made dynamic and switchable. The service device enables the presider to dynamically transition between conference mode and private call mode at will, without being locked into a single static state. This dynamic capability allows flexible adaptation to different communication needs while maintaining both conference participation and private conversation abilities.

AI summary
The present application discloses a method for realizing a private call during a conference in an IP multimedia subsystem, which includes the following steps: a service device receives a first request message that is sent by a first communication device to request a private call with a second communication device; if the first communication device is a communication device at the conference presider side, the service device modifies conference media of the communication device having participated in the conference within the first and the second communication devices; and after modifying the conference media, the service device establishes a private call between the first and the second communication devices. The present application also correspondingly discloses a service device for realizing a private call during a conference in an IP multimedia subsystem. In the present application, after a request for a private call is received, the conference media of the conference presider and/or conference members is modified, thus enabling the conference presider or conference members to make a private call with the conference members or the conference presider freely or as needed.
