Terminal Device 5G Icon Display via RRC Connection Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G network icon display on terminal devices, existing solutions face challenges in reducing power consumption and improving the display camping ratio of 5G network icons, leading to poor user experience due to frequent network icon switching and potential network instability misconceptions.
Innovation Solution
A network icon display method that involves a terminal device using dual connectivity technology to switch from a 4G connected mode to an idle mode, actively requesting the network side to release the RRC connection when preset conditions are met, such as no user traffic or specific power-saving modes, to display the 5G network icon and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device maintains RRC connection in 4G connected mode after switching from dual connectivity, then network service responsiveness is improved, but power consumption increases and 5G network icon display ratio decreases
Solution Approach 1:
The terminal device dynamically switches between 4G connected mode and 4G idle mode based on service requirements. When service is needed, it maintains RRC connection in connected mode; when service is not needed, it releases RRC connection to enter idle mode, achieving adaptive power saving while ensuring service responsiveness when required
Solution Approach 2:
The terminal device changes the RRC connection state parameter between connected and idle modes. By setting specific conditions (service availability, time thresholds) for mode switching, it optimizes the balance between power consumption and network service responsiveness, thereby improving overall system efficiency
2Reliability
If the terminal device maintains RRC connection in 4G connected mode, then network service availability is improved, but the display camping ratio of 5G network icon deteriorates
Solution Approach 1:
The terminal device dynamically adjusts its RRC connection state based on service requirements. By entering idle mode when service is not needed, it enables continuous 5G network icon display, improving the display camping ratio while maintaining service availability when actually required
Solution Approach 2:
The terminal device autonomously determines when to switch between connected and idle modes based on its own service status. It self-manages the RRC connection state without continuous network control, enabling it to optimize 5G icon display while ensuring service availability when needed
3Use of energy by moving object
If the terminal device actively requests RRC connection release, then power consumption is reduced and 5G network icon display is improved, but network connection stability may be affected
Solution Approach 1:
The terminal device performs preliminary assessment of service requirements before requesting RRC connection release. By checking service availability and setting time thresholds in advance, it ensures that connection release requests are only made when appropriate, preventing premature disconnection and maintaining network stability
Solution Approach 2:
The terminal device implements feedback mechanisms by monitoring service status and time thresholds before requesting connection release. This feedback control ensures that RRC connection is only released when service is truly not needed, preventing unstable connection behavior while achieving power saving goals

AI summary
This application provides a network icon display method and device, and relate to the field of electronic technologies. The method comprises: A terminal device is connected to a long term evolution LTE cell and a new radio NR cell by using a dual connectivity technology, and the LTE cell supports a non-standalone NSA networking mode. The terminal device displays a 5G network icon. After disconnecting from the NR cell, the terminal device enters a 4G connected mode. If the terminal device meets a preset condition, the terminal device sends first request information to a network side device, where the first request information is used to request to release the connection between the terminal device and the LTE cell. In response to releasing the connection between the terminal device and the LTE cell, the terminal device enters a 4G idle mode, and displays the 5G network icon.
