Network Access Control Privilege Elevation for Collaboration Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks often conduct collaboration sessions at the privilege level corresponding to the lowest role of users participating, which can result in suboptimal video quality and communication efficiency due to inadequate network access management.
Innovation Solution
The system manages Network Access Control (NAC) privileges based on communication context awareness, assigning at least the privileges corresponding to the user with the highest role to users with lower roles during collaboration sessions, optimizing network access and improving communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network conducts collaboration sessions at the privilege level corresponding to the lowest role of users, then network security and access control are maintained, but video quality and communication efficiency deteriorate
Solution Approach 1:
The system dynamically adjusts NAC privileges during collaboration sessions based on real-time context awareness. Instead of static privilege assignment, the system monitors user roles, device types, and session requirements to temporarily elevate privileges for users with lower roles, enabling high-definition video and efficient communication while maintaining security through time-bound, context-specific access control
Solution Approach 2:
The system applies different privilege levels to different users within the same collaboration session based on their specific needs and roles. Rather than uniformly assigning the lowest common privilege level to all participants, the system grants elevated privileges locally to specific users who require them for optimal communication quality, while other users maintain their standard privilege levels
2Reliability
If the network assigns QoS privileges based on service level agreements, then network access control is maintained, but communication quality deteriorates when users need higher privileges temporarily
Solution Approach 1:
The system enables users to self-assign temporary QoS privileges to one another during collaboration sessions without requiring service provider intervention. Users with appropriate authorization can dynamically adjust each other's NAC privileges based on session requirements, allowing for flexible quality improvements while maintaining overall access control policies
Solution Approach 2:
The system pre-configures authorization rules and policies that define which users can grant elevated privileges to others under specific conditions. Before collaboration sessions begin, the system establishes the framework for temporary privilege escalation, enabling users to quickly adjust privileges during sessions without ad-hoc service provider involvement

AI summary
Methods and systems for managing NAC privileges based on communication context awareness are provided. In one aspect, a method includes detecting, by a network server, a collaboration session between at least first and second users and retrieving, by a network server from a directory server, a first role of the first user that corresponds with privileges including a first quality of service level. Further, the network server retrieves a second role of the second user that corresponds with privileges including a second quality of service level. Also, the method includes determining that the first quality of service level is greater than the second quality of service level and assigning the second user at least the privileges corresponding to the first role. The collaboration session is conducted between the first user and the second user based on the privileges assigned to the second user that correspond to the first role.
