Solution Overview

Problem

In future 5G communication networks, the high signaling overhead and access delay are significant issues due to a large number of user equipment (UEs) accessing the network with a small amount of data, leading to inefficiencies in connection management and data transmission.

Innovation Solution

Implementing light connection control methods in user equipment (UEs) by acquiring and utilizing data information such as power-saving mode, data buffer, light connection, type, service, capability, and paging valid time to optimize connection management, reduce signaling overhead, and minimize access delay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional connection management is used for all UEs, then connection reliability is maintained, but signaling overhead increases and access delay increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent segments UE management into two distinct categories: light connection UEs (for small data transmissions) and traditional connected UEs (for regular data transmissions). By dividing the UE population based on data transmission characteristics, the system applies different connection management strategies to each segment, reducing overall signaling overhead while maintaining connection reliability for both types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by implementing connection management policies tailored to specific UE characteristics. Light connection UEs receive simplified connection handling with reduced signaling procedures, while traditional UEs maintain full connection management. This localized approach optimizes resource usage for each UE type based on its specific needs.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If traditional connection management is used for all UEs, then connection stability is maintained, but access delay increases

Engineering Contradiction:

Improveconnection stabilityVSAvoidaccess delay

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-configuring light connection parameters and policies for UEs identified as suitable for light connection mode. This advance preparation allows these UEs to bypass certain connection setup procedures, reducing access delay while maintaining connection stability through pre-established parameters.

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If light connection control is implemented, then signaling overhead is reduced, but device complexity increases

Engineering Contradiction:

Improvesignaling overheadVSAvoidconnection control complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent implements dynamic connection control by allowing UEs to transition between light connection mode and traditional connected mode based on real-time data transmission needs. The system dynamically adjusts connection management strategies, UE characteristics, and data transmission parameters, providing flexibility while managing complexity through adaptive rather than static control mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies self-service by enabling UEs to self-identify their suitability for light connection mode based on their data transmission characteristics. The UE autonomously determines whether it qualifies for light connection handling, reducing the burden on the network side and simplifying overall system complexity while still achieving signaling overhead reduction.

Inventive Principle:

Principle #25Self-service
