Dynamic UE Policy Generation via Network Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UE policy configuration in roaming and Standalone Non-Public Networks is inflexible, as it is based on predefined protocols, failing to consider the actual conditions of roaming or visit networks, leading to poor policy flexibility.
Innovation Solution
A method and apparatus where a first network function sends UE policy assistance information to a second network function, enabling it to dynamically generate, configure, or update the UE policy based on current network and service conditions, incorporating information such as URSP, application details, and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE policy is generated based on predefined protocols, then the policy configuration is standardized and reliable, but the flexibility and adaptability to actual network conditions deteriorates
Solution Approach 1:
The patent implements dynamic policy generation by allowing the second network function to create UE policies based on real-time network conditions and service requirements rather than static predefined protocols. The policy can be dynamically adjusted according to actual roaming network status, visit network conditions, and current service demands, making the system adaptive while maintaining reliability through structured information exchange.
Solution Approach 2:
The patent changes the parameters of policy generation from fixed protocol-defined values to dynamic parameters including network condition indicators, service type information, and roaming status data. By modifying these parameters based on actual network state, the system achieves both reliability through standardized parameter structures and flexibility through adaptive parameter values.
2Productivity
If UE policy is generated based on predefined rules, then the processing is simple and fast, but the accuracy of policy matching actual network conditions deteriorates
Solution Approach 1:
The patent applies preliminary action by having the first network function collect and prepare network condition information, service requirements, and roaming status data before the actual policy generation occurs. This pre-processing of relevant parameters enables the second network function to generate accurate policies quickly without having to analyze raw network data in real-time, thus maintaining high productivity while improving accuracy.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first network function acts as a mediator that gathers actual network conditions and translates them into structured assistance information for the second network function. This intermediary layer ensures accurate representation of network state while maintaining efficient processing through standardized information formats.
3Device complexity
If the H-PCF generates policy without considering current network situation, then the processing is straightforward, but the adaptability to roaming and visit network conditions deteriorates
Solution Approach 1:
The patent segments the policy generation process into two distinct parts: the first network function that collects and analyzes network conditions, and the second network function that generates the actual policy. This segmentation allows each function to specialize - one in data collection and analysis, the other in policy creation - reducing overall complexity while improving adaptability through dedicated functionality.
Solution Approach 2:
The first network function serves as an intermediary that bridges the gap between actual network conditions and the policy generation process. It collects detailed network status information from roaming and visit networks, processes this information into standardized assistance data, and provides it to the second network function, enabling adaptive policy generation without significantly increasing the complexity of the core policy processing logic.
