Conference Server Participant Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a method to dynamically manage participant access in ongoing conference sessions, particularly in terms of admitting new users as full or partial participants based on privacy and permission levels, which can lead to uncontrolled communication between participants.
Innovation Solution
A conference server determines participant access by referring to stored conference rules, allowing admission as a full or partial participant, and selectively enables or disables communication with specific participants based on privacy and permission levels, using protocols like SIP and RTP for managing conference legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conference server admits all new participants as full participants, then the ease of operation is improved, but the privacy and security are worsened
Solution Approach 1:
The patent applies local quality by differentiating participant access rights based on individual permission levels. Instead of uniform full access for all participants, the system grants different levels of access (full participant vs. partial participant) according to each user's authorized scope, thereby maintaining ease of joining while preventing privacy violations through differentiated local access control.
Solution Approach 2:
The system changes the parameter of access permission by introducing a permission level attribute that can take different values (e.g., full participant, partial participant). This parameter change enables the conference server to dynamically adjust the scope of communication based on user authorization, resolving the contradiction between easy access and privacy protection.
2Object-affected harmful factors
If the conference server implements strict permission-based access control, then the privacy and security are improved, but the device complexity is worsened
Solution Approach 1:
The patent implements self-service by having the conference server automatically determine access levels based on pre-stored permission level information associated with each participant. The server autonomously evaluates permission levels and configures access rights without requiring manual intervention or complex configuration processes, thereby strengthening privacy protection while avoiding excessive system complexity.
Solution Approach 2:
The system applies preliminary action by pre-storing permission level information for each participant before the conference begins. This pre-configured data enables the conference server to quickly and automatically determine access rights during the conference, eliminating the need for real-time complex access control decisions and reducing operational complexity while maintaining strong privacy security.
3Adaptability or versatility
If the conference server allows selective communication with specific participants, then the adaptability is improved, but the device complexity is worsened
Solution Approach 1:
The patent uses parameter changes by introducing a permission level parameter that defines the scope of communication for each participant. The conference server uses this parameter to automatically determine which participants can communicate with each other, enabling flexible and adaptable communication control without requiring complex manual configuration or management of individual communication rules.
Data Source
AI summary
A method and system are provided for admitting new participants to an ongoing conference session. In one example, a conference server hosting a conference session may receive a request for a UE to join the ongoing conference session. In response to receiving such a request, the conference server may determine whether to admit the UE to the ongoing conference session as a full participant or as a partial participant. When the conference server determines to admit the UE as a full participant, the conference server establishes a conference leg with the UE and permits the UE to communicate with each and every current participant of the ongoing conference session. However, when the conference server determines to admit the UE as a partial participant, the conference server may establish a conference leg with the UE and may permit the UE to communicate with just some of the ongoing conference's current participants.
