Multi-SIM 5G NSA Dual Connectivity Control for Lower Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals face battery waste due to unnecessary connection attempts to 5G networks when they do not require 5G services, leading to increased power consumption and signaling overhead.
Innovation Solution
Implementing a method and apparatus that control dual connectivity based on the type of SIM used for the current communication service, allowing terminals with multiple SIMs to disable dual connectivity features when not needed, thereby preventing connection procedures to 5G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal maintains dual connectivity to both 4G and 5G networks, then service coverage and reliability are improved, but power consumption increases due to unnecessary connection procedures
Solution Approach 1:
The terminal dynamically adjusts its connectivity state based on service requirements. When 5G services are not needed, the terminal releases the 5G connection and maintains only 4G connectivity, thereby reducing power consumption while preserving service coverage when needed
Solution Approach 2:
The terminal changes its network connection parameters based on the type of SIM card inserted and service requirements. By detecting whether a first SIM or second SIM is active, the terminal adjusts its dual connectivity configuration accordingly, enabling or disabling 5G connections to optimize power consumption
2Productivity
If a terminal performs connection procedures to 5G network, then access to high-speed services is enabled, but signaling overhead increases
Solution Approach 1:
The terminal performs partial connection procedures by maintaining only the necessary 4G connection when 5G services are not required. This avoids the excessive signaling overhead associated with full dual connectivity while still providing adequate service through 4G alone
