5G NSA Capability Control via SIM-Based Dual Connectivity Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminals face battery waste due to continuous connection attempts to 5G networks when they do not require 5G services, leading to increased power consumption and unnecessary signaling overhead.
Innovation Solution
Implementing a method to disable dual connectivity in terminals when they do not need to receive 5G services by determining the type of SIM used for current communication services and transmitting this information to the base station, thereby preventing connection procedures with the 5G network and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal maintains dual connectivity with both 4G and 5G networks, then service coverage and reliability are improved, but power consumption increases due to continuous connection attempts to 5G network
Solution Approach 1:
The terminal dynamically adjusts its network connectivity state based on service requirements. When 5G services are not needed, the terminal transitions from dual connectivity to 4G-only mode, thereby reducing power consumption while maintaining service reliability when needed
Solution Approach 2:
The terminal changes the connectivity parameter (dual connectivity enabled/disabled) based on whether 5G services are required. This parameter change allows the terminal to optimize between service coverage and power consumption by selecting the appropriate connectivity mode
2Productivity
If a terminal performs connection procedures with 5G network, then access to high-speed services is enabled, but signaling overhead increases unnecessarily when 5G services are not required
Solution Approach 1:
The terminal extracts or removes the unnecessary 5G connection procedure when 5G services are not required. By taking out the redundant signaling steps, the terminal reduces signaling overhead while maintaining the capability to access high-speed services when needed
