Solution Overview

Problem

Current wireless communication systems have limited application scope for user plane data, restricting its use in advanced applications like big data analysis and network status monitoring, as they primarily transmit data to external application servers rather than allowing it to be forwarded to core network control plane elements.

Innovation Solution

A method where a mobile network element transmits a first identifier to terminal devices or network devices, enabling them to transfer data packets to corresponding network elements, such as SMF, NEF, or NWDAF entities, thereby expanding the application scope of user plane data for purposes like big data analysis and network status monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If user plane data is transmitted only to external application servers through network protocol addresses, then the transmission path is simple and direct, but the application scope of user plane data is limited

Engineering Contradiction:
Improveapplication scope of user plane dataVSAvoiddata transmission path complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The user plane data transmission path is designed to support multiple functions: traditional external application server access and new core network control plane element access. The system can route data to different destinations based on the destination address type (external server address or core network element address), enabling the same user plane to serve multiple purposes without requiring separate dedicated paths for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The UPF (User Plane Function) acts as an intermediary that receives data from the terminal device and intelligently routes it based on the destination address. When the address indicates a core network control plane element, the UPF forwards data through the control plane; when it indicates an external application server, the UPF forwards data through the user plane. This intermediary routing mechanism enables multi-functionality without requiring the terminal device to understand the complex routing logic

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If user plane data is forwarded to core network control plane elements, then advanced applications like big data analysis and network status monitoring are enabled, but the data transmission architecture becomes more complex

Engineering Contradiction:
Improvedata application scenariosVSAvoidnetwork element interaction complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different parts of the network architecture are assigned different qualities and functions: the user plane handles traditional data transmission to external servers, while the control plane handles data routing to core network elements for analytics. The UPF is positioned at the boundary between these planes and performs intelligent routing based on destination address analysis. This local quality differentiation allows each component to specialize in its function while the system as a whole achieves versatility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The data transmission path is segmented into distinct planes: user plane for external server access and control plane for core network element access. The UPF acts as the segmentation point that directs data packets to the appropriate plane based on the destination address. This segmentation allows independent optimization and management of each plane while enabling the system to support diverse applications through coordinated operation of both planes

Inventive Principle:
Principle #1Segmentation
