Unified Conference Service Setup via SIP Signaling Path Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conference service implementation in packet-switched networks is inefficient due to complex steps required for conference creation and participant addition, which disrupts ongoing services and fails to maintain prior service experiences.
Innovation Solution
A method and system that combine conference creation and participant invitation into a single operation, utilizing a conference operation message carrying initiator and participant information to add users to a conference, and reusing the signaling path of established conversations to simplify the conference creation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing conference service implementation procedure is used, then the conference can be created and participants can be added, but the process becomes complex and inefficient with multiple separate steps required
Solution Approach 1:
The patent merges the conference creation function and participant invitation function into a single integrated operation. When a user initiates a conference call, the system automatically creates the conference and invites participants in one unified process, eliminating the need for separate conference creation and participant addition steps. This is achieved by modifying the SIP protocol to include conference creation parameters in the initial INVITE message, allowing the conference bridge to be established and participants to be added simultaneously.
2Adaptability or versatility
If the existing conference service implementation procedure is used, then the conference can be created, but ongoing services are disrupted and prior service experiences are lost
Solution Approach 1:
The patent applies preliminary action by establishing the conference bridge and signaling path before the actual conference call is initiated. The system pre-configures the conference resources and maintains the signaling path of the original call, ensuring that when participants are added to the conference, the original service context is preserved. This allows ongoing services to continue uninterrupted while the conference is being set up and participants are being added.

AI summary
An apparatus and a system for implementing the conference service is disclosed. The method includes: a conference initiator sends a conference operation message that carries conference information which includes conference initiator information and information of at least one conference participant, or includes information of more than one conference participant; adds more than one user terminal denoted by the conference information to the conference. With the present invention, only one operation is needed to set up a conference. The implementation of conference service is greatly simplified.
