5G Traffic Steering via QoS and SPID Data Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in dynamically managing data traffic based on quality of service (QoS) and subscriber profile identification (SPID), particularly in prioritizing public safety services during crises, leading to inefficient resource utilization and user experience.
Innovation Solution
Implementing a traffic steering algorithm that monitors conditions such as buffer thresholds and radio quality, allowing the Scheduler to dynamically switch between LTE and NR links to optimize data routing based on QoS or SPID, ensuring high-priority services receive preferred throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traffic is dynamically managed based on QoS and SPID to prioritize public safety services, then user experience and service reliability are improved, but network complexity and resource management overhead increase
Solution Approach 1:
The patent implements dynamic traffic steering that adapts network resource allocation in real-time based on QoS parameters and SPID values. The system continuously monitors network conditions and automatically adjusts data routing between LTE and 5G networks, enabling flexible response to changing service requirements without manual intervention
Solution Approach 2:
The system employs feedback mechanisms where the Scheduler receives QoS information and SPID data, processes this information through the traffic steering algorithm, and adjusts data routing decisions accordingly. This closed-loop control ensures that public safety services receive prioritized treatment while maintaining overall network efficiency
2Productivity
If the Scheduler dynamically switches between LTE and NR links to optimize data routing, then network resource utilization is improved, but processing complexity and decision-making overhead increase
Solution Approach 1:
The patent segments data traffic into different QoS classes and SPID categories, allowing the Scheduler to handle each segment according to its specific requirements. This segmentation enables public safety traffic to be separately identified and prioritized, while commercial traffic is managed according to standard procedures, reducing overall processing complexity through structured organization
Solution Approach 2:
The system utilizes QoS parameters and SPID values as changing variables to dynamically adjust data routing decisions. By monitoring these parameters and adjusting traffic steering based on their values, the Scheduler can optimize network resource utilization without requiring complex algorithms, as the parameter changes provide clear decision-making criteria
3Reliability
If high-priority services receive preferred throughput through traffic steering, then service quality is improved, but fairness to other users and overall network equity deteriorate
Solution Approach 1:
The patent applies local quality differentiation by providing enhanced service quality specifically to public safety users identified through SPID values and QoS parameters, while maintaining standard service quality for commercial users. This localized quality enhancement ensures that priority services receive necessary resources during crises without fundamentally altering the service model for other users
Solution Approach 2:
The system implements partial prioritization where public safety traffic receives preferred throughput only when needed, as determined by QoS indicators and SPID classification. This partial action approach allows the network to provide excessive resources to priority services during emergencies while maintaining normal resource allocation for other users during non-critical periods, thus preserving overall network equity
