Network Device Service Authorization for NCIS Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in authorizing terminal devices for network-controlled interactive services (NCIS) required for applications like augmented reality (AR) and virtual reality (VR) games, which demand high service quality and specific network configurations.
Innovation Solution
A service authorization method is introduced where the network device sends specific information to the terminal device, indicating allowed services, radio access technologies, quality of service parameters, and interface usage permissions, enabling the terminal device to support NCIS by authorizing the necessary connections and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device sends detailed authorization information to the terminal device, then the service quality and reliability for NCIS are improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The authorization information is segmented into multiple distinct parameters including allowed services, radio access technologies, quality of service parameters, and interface usage permissions. This segmentation allows the terminal device to process and implement each authorization aspect independently, reducing overall complexity while maintaining comprehensive service quality control.
Solution Approach 2:
The network device performs preliminary authorization by sending all necessary service configuration information to the terminal device before the NCIS session begins. This preliminary action ensures that the terminal device has all required parameters pre-configured, eliminating the need for complex real-time authorization decisions during service operation.
2Adaptability or versatility
If the network device authorizes multiple radio access technologies and interfaces, then the adaptability and versatility of the service are improved, but the difficulty of detecting and measuring service parameters increases
Solution Approach 1:
The patent applies local quality by providing specific authorization parameters for different radio access technologies and interfaces individually. Each technology and interface receives tailored authorization information appropriate to its specific requirements, enabling precise control and measurement for each communication path rather than using a blanket authorization approach.
Solution Approach 2:
The authorization mechanism is designed with universality by creating a standardized framework that can accommodate multiple radio access technologies and interface types through a common parameter structure. This universal approach allows the same authorization mechanism to manage diverse technologies without requiring separate detection and measurement procedures for each.
3Productivity
If the network device provides comprehensive service information including QoS parameters and interface permissions, then the productivity and service quality are improved, but the loss of information and processing overhead increase
Solution Approach 1:
The patent extracts only the essential service parameters needed for NCIS operation from the complete service information available at the network device. By selecting and transmitting only the critical parameters (allowed services, RATs, QoS, interface permissions) rather than all possible service information, the solution reduces information processing overhead while maintaining sufficient productivity for service setup.
