5G Icon Display Control After NR Secondary Cell Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network icons on electronic terminals frequently fluctuate between 4G and 5G, misleading users about network stability due to the release of NR secondary cells, even when the terminal remains within NR coverage, affecting user experience and brand reputation.
Innovation Solution
An icon display method that controls the electronic terminal to display a 5G icon after establishing dual connections with LTE and NR networks, and detects the ability to access an NR secondary cell after a preset time, continuing the 5G display if access is maintained, using various detection methods to ensure accurate network state reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal displays network icons based on real-time connection status, then the icon updates reflect current network state, but the icon fluctuates frequently between 4G and 5G when NR secondary cells are temporarily released, misleading users about network stability
Solution Approach 1:
The system performs preliminary detection of NR network coverage capability before determining icon display. When the terminal is in RRC idle state, it proactively checks whether it can access NR secondary cells in the current area. This preliminary action allows the system to maintain 5G icon display based on coverage capability rather than temporary connection state, preventing unnecessary icon fluctuations while preserving accurate network state reflection.
2Use of energy by moving object
If the terminal releases RRC connection of LTE network when no data transmission occurs, then power consumption is reduced, but the NR secondary cell is also released causing the 5G icon to disappear even though the terminal remains in NR coverage
Solution Approach 1:
The system implements a feedback mechanism where, after releasing the RRC connection in idle state, the terminal detects whether it can still access NR secondary cells in the current area. This feedback information about NR coverage capability is used to determine whether to display the 5G icon, ensuring that the icon accurately reflects network coverage availability rather than temporary connection state, thus preventing loss of network coverage information.
3Reliability
If the terminal maintains dual connections with LTE and NR networks continuously, then network coverage information is preserved, but power consumption increases and rapid coverage is compromised
Solution Approach 1:
Instead of maintaining continuous dual connections, the system performs preliminary detection of NR coverage capability when needed (such as when transitioning to idle state or when icon display needs to be determined). This on-demand detection approach preserves network coverage information reliability while avoiding the continuous power consumption of maintaining active dual connections, thus resolving the contradiction between reliability and energy usage.

AI summary
An icon display method for an electronic device is provided. The method includes: controlling the electronic terminal to display a 5G icon, after the electronic terminal establishes dual connections with an LTE network and an NR network; detecting whether the electronic terminal can currently access an NR secondary cell after a first preset time period is delayed, when an NR secondary cell accessed by the electronic terminal is released; and controlling the electronic terminal to continue to display the 5G icon if yes. A computer-readable storage medium and an electronic terminal are also provided.
