Solution Overview

Problem

In the transition from 4G to 5G networks, the limited radio frequency power of terminals poses a risk of reduced network coverage and security when both LTE and NR transmission powers are high, particularly in non-standalone (NSA) networking modes.

Innovation Solution

A network connection method where a terminal receives a connection indication from a base station, initiates a service monitoring function, and determines a target network mode based on current service type parameters, transmitting this mode to the base station for connection, allowing for optimal network selection between LTE and NR to meet power requirements and enhance security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the terminal connects to both LTE and NR networks simultaneously in NSA mode, then the data rate and network capability are improved, but the radio frequency power consumption increases and network coverage security deteriorates

Engineering Contradiction:
Improvedata rateVSAvoidradio frequency power
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic network mode selection that adjusts the connection strategy between LTE and NR based on real-time service requirements. The terminal determines whether to use time-sharing or simultaneous connection mode depending on the service type, making the system adaptable rather than static. This resolves the contradiction by allowing high data rates when needed while conserving power when services don't require it.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of network connection by introducing service-type-dependent connection modes. For different service types (e.g., enhanced mobile broadband vs. ultra-reliable low-latency communication), the system adjusts connection parameters such as whether to maintain simultaneous LTE-NR connections or use time-sharing, thereby optimizing the balance between data rate and power consumption.

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If the terminal uses high transmission power for both LTE and NR, then the network coverage is improved, but the terminal security and reliability deteriorate due to power limitations

Engineering Contradiction:
Improvenetwork coverageVSAvoidterminal security
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The system dynamically adjusts connection strategies based on service requirements rather than maintaining fixed high-power connections. By selecting time-sharing mode for certain services and simultaneous mode for others, the terminal avoids sustained high power consumption that would compromise reliability, while still achieving adequate coverage when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The terminal autonomously determines its own connection strategy by evaluating service type requirements and selecting appropriate connection modes without requiring external control. This self-service capability allows the terminal to manage its power resources responsibly, maintaining security and reliability while providing sufficient network coverage.

Inventive Principle:
Principle #25Self-service

3Speed

If the terminal selects network mode based on fixed rules, then the connection speed is improved, but the adaptability to different service types deteriorates

Engineering Contradiction:
Improveconnection speedVSAvoidservice type adaptability
Core Design Contradiction:
SpeedVSAdaptability or versatility

Solution Approach 1:

The patent makes the network mode selection dynamic by baseing it on service type classification. Instead of fixed rules, the system adapts its connection strategy (time-sharing vs. simultaneous mode) according to the specific service requirements, achieving both fast connection establishment and high adaptability to different service types.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes connection parameters based on service type identification. By categorizing services and assigning appropriate connection modes, the patent achieves rapid adaptation to different service requirements while maintaining fast connection speeds through predetermined mode selections for each service category.

Inventive Principle:
Principle #35Parameter changes
