Solution Overview

Problem

Existing communication systems for data exchange between terminal devices and application servers in operator trust domains face inefficiencies, particularly in routing data within the operator trust domain, which can lead to increased latency and resource utilization.

Innovation Solution

The proposed solution involves a network exposure node, such as an SCEF or NEF, that receives configuration information from an application server within the operator trust domain. This node then forwards data between the terminal device and the application server based on the received configuration, optimizing data routing within the operator trust domain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If data is routed through traditional network paths between terminal device and application server, then data delivery is achieved, but latency increases and resource utilization deteriorates

Engineering Contradiction:
Improvedata delivery latencyVSAvoidresource utilization
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The network exposure node pre-configures data delivery paths and parameters before actual data transmission occurs. Configuration information including routing rules, QoS parameters, and delivery policies is established in advance, enabling the node to immediately forward data along optimized paths without real-time routing decisions, thus reducing latency and improving resource utilization efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The network exposure node acts as an intermediary entity between the terminal device and application server. It receives configuration information from the application server, manages data delivery based on predefined rules, and forwards data without requiring complex real-time interactions between the terminal device and server, thereby simplifying the communication path and reducing delivery time

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If configuration information is received from application server for data delivery, then data routing efficiency is improved, but network node complexity increases

Engineering Contradiction:
Improvedata routing efficiencyVSAvoidnetwork node complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The network exposure node separates configuration management functions from data forwarding functions. Configuration information (routing rules, QoS parameters, delivery policies) is received and stored separately from actual data traffic. This segmentation allows the node to efficiently forward data based on pre-configured rules without complex real-time decision-making, improving routing efficiency while keeping the node's operational complexity manageable

Inventive Principle:
Principle #1Segmentation

AI summary

Methods and apparatuses are disclosed for data communication between terminal device and application server. According to an embodiment, a network exposure node receives, from a first application server in operator trust domain, configuration information that can be used for data delivery for a terminal device. The network exposure node receives data from one of the terminal device and the first application server and forwards the data to the other of the terminal device and the first application server based on the configuration information.
