Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and inefficiency in managing predefined Policy and Charging Control (PCC) rules in 5G networks, particularly in supporting configurable 5QIs, are not adequately addressed by current network management systems.
Innovation Solution
The implementation of predefined PCC rule management and support for configurable 5QIs through the definition of new information object classes (IOCs) and dataTypes in the Network Resource Model (NRM), enabling the Policy and Charging Rules Function (PCF) to manage and monitor these rules effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current network management systems are used to manage predefined PCC rules, then basic rule management is possible, but the system cannot adequately support configurable 5QIs and becomes increasingly complex and inefficient
Solution Approach 1:
The patent segments the PCC rule management system into distinct functional components: a rule repository storing template PCC rules with configurable 5QIs, a rule selection function that retrieves and configures appropriate rules, and a rule enforcement function that applies selected rules. This segmentation allows the system to support configurable 5QIs while managing complexity through modular architecture.
Solution Approach 2:
The patent implements preliminary action by pre-configuring template PCC rules in the rule repository with various 5QI parameter configurations before runtime. These templates include predefined structures for different service types (e.g., eMBB, URLLC, mMTC) with configurable parameters, allowing the system to quickly instantiate appropriate rules without complex real-time configuration decisions.
2Reliability
If more PCC rules and configurable 5QIs are managed, then QoS control capability is improved, but management efficiency deteriorates
Solution Approach 1:
The patent applies universality by creating a rule template system where a single template PCC rule can serve multiple service types and scenarios through parameter configuration. The template structure includes universal elements (packet filters, QoS parameters, enforcement rules) that can be instantiated for different 5QI configurations, allowing one template to fulfill multiple specialized functions and improving management efficiency.
Solution Approach 2:
The patent implements copying by allowing the system to replicate and instantiate template PCC rules multiple times with different configuration parameters. Instead of managing separate detailed rules for each service scenario, the system creates copies of templates with customized 5QI parameters, significantly reducing the management overhead while maintaining comprehensive QoS control capability across diverse service types.

AI summary
A method and system for managing predefined PCC rules and 5QIs in a 5G network are described. The predefined PCC rules and 5QIs are assigned to a PCF and/or SMF and managed by a MOI of an IOC modelling the PCC rule and 5QIs. Attributes of the MOIs are specific to the PCC rule and 5QIs being managed.
