Terminal Network Connection Mode Selection in NSA Networks
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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.

AI summary
Disclosed are a network connection method, a terminal, a base station, and a computer storage medium, the network connection method including receiving, by the terminal, a connection indication from a base station when in a non-standalone (NSA) networking. The connection indication includes a target connection mode. The method further includes initiating, by the terminal, a preset service monitoring function when the target connection mode is a preset time-sharing connection mode; acquiring, by the terminal, a current service type; and determining, by the terminal, a target network mode according to the current service type. The target network mode is one of multiple network modes in the NSA networking. The method further includes in response to the connection indication, transmitting, by the terminal, the target network mode to the base station for connection with the target network mode.
