Solution Overview

Problem

In congested networks or when UE policies have a large amount of data, existing methods struggle to efficiently configure policies for terminal devices, leading to increased signaling overheads.

Innovation Solution

A network device determines a target policy based on current time and position information of the terminal device, sending only the necessary policy instead of all policies, and updates the policy as time or position changes, using pre-stored correspondences between time/position and policy rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all UE policies are delivered to terminal devices, then policy completeness is improved, but signaling overhead increases

Engineering Contradiction:

Improvepolicy completenessVSAvoidsignaling overhead

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary target policy from the complete set of UE policies based on terminal device conditions (time, position, network status) and delivers only that specific policy to the terminal device, rather than transmitting all policies. This extraction approach maintains policy effectiveness while reducing signaling overhead.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by customizing policy delivery according to specific terminal device conditions such as current time, position information, and network congestion status. Different terminal devices receive different target policies tailored to their local context, ensuring policy relevance while minimizing unnecessary data transmission.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If UE policy data amount is large, then policy coverage is improved, but transmission efficiency deteriorates

Engineering Contradiction:

Improvepolicy coverageVSAvoidtransmission efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the complete UE policy set into multiple individual policies, each associated with specific conditions (time ranges, position areas, network states). The network device then selectively delivers only the relevant segment (target policy) matching the terminal device's current conditions, improving transmission efficiency while maintaining comprehensive policy coverage across different scenarios.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by delivering only the minimum necessary policy information (target policy) required for the terminal device to operate under current conditions, rather than transmitting the complete policy set. This partial delivery approach achieves sufficient policy coverage for current needs while significantly improving transmission efficiency.

Inventive Principle:

Principle #16Partial or excessive action
