Solution Overview

Problem

M2M devices face challenges in correctly transmitting data to the underlying network due to the inability of the DH module to determine the content of the data, leading to incorrect use of communication paths, where data meant for the control plane is transmitted through the user plane.

Innovation Solution

The proposed solution involves creating a specialized underlying network information resource within the CSE to store data for calling an underlying network service, allowing the CSE to update and transmit this data using the control plane, ensuring that M2M devices can accurately transmit data to the underlying network by distinguishing between user plane and control plane data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the DH module transmits data without determining content, then the transmission process is simple, but data for calling underlying network service is incorrectly transmitted through user plane instead of control plane

Engineering Contradiction:
Improvetransmission process complexityVSAvoiddata transmission accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces a dedicated underlying network service information resource as an intermediary between the DH module and the transmission path selection mechanism. This resource stores data for calling underlying network services, allowing the CSE to identify such data and route it through the control plane via NSE module, while ordinary data continues through the user plane via DH module, thus resolving the contradiction between transmission simplicity and accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a specialized resource for storing underlying network service data is created, then data transmission accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvedata transmission accuracyVSAvoidsystem structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the underlying network service information resource within the existing CSE architecture, allowing the CSE to serve multiple functions: managing ordinary data transmission through DH module and managing underlying network service data transmission through NSE module. This multi-functionality approach minimizes additional system complexity while achieving accurate data transmission routing.

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

Solution Approach 2:

The patent changes the state parameter of data by storing it in a specialized resource with distinct identification characteristics. This parameter change enables the CSE to differentiate between ordinary data and underlying network service data, allowing accurate routing decisions without requiring complex structural modifications to the overall system.

Inventive Principle:
Principle #35Parameter changes

3Speed

If all data is transmitted through user plane, then transmission speed is fast, but service calling functionality is lost

Engineering Contradiction:
Improvedata transmission speedVSAvoidservice calling capability
Core Design Contradiction:
SpeedVSAdaptability or versatility

Solution Approach 1:

The patent segments the data transmission path into two distinct routes: user plane for ordinary data transmission (maintaining high speed) and control plane for underlying network service data transmission (enabling service calling functionality). The specialized resource enables this segmentation by identifying which data requires control plane transmission, thus preserving both speed and functionality.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present invention provide a data transmission processing method and apparatus, where the method includes: receiving, by a common services entity CSE, a first request message that is sent by an application function AF module and used to instruct the CSE to update a first underlying network information resource, where the first request message includes data for calling an underlying network service, and the first underlying network information resource is a resource specially used to store the data for calling an underlying network service; updating, by the CSE, original data in the first underlying network information resource to the data for calling an underlying network service; and sending, by the CSE, the data for calling an underlying network service in the first underlying network information resource to an underlying network by using a control plane.
