Network Indicator Selection for LTE and 5G Dual Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for electronic devices to effectively display the type of network and network services provided, particularly in 5G networks, where dual connectivity with 4G and 5G RANs is used, and users need to be notified of the network type and service type, such as eMBB, URLLC, or mMTC, for enhanced user experience.
Innovation Solution
An electronic device equipped with a touch screen, a communication module comprising LTE and NR communication circuits, and a processor that receives a system information block (SIB) and a restrict DCNR bit from an LTE base station, identifying operator information to display an LTE or 5G indicator based on the received information, indicating the availability of dual connectivity with the 5G network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic device displays multiple network indicators (LTE and 5G) to provide comprehensive network information, then the information completeness is improved, but the display complexity increases
Solution Approach 1:
The patent applies local quality by displaying different network indicators (LTE vs. 5G) in different display regions or contexts based on the specific network configuration and operator policies. The display adapts its content quality locally rather than uniformly across all scenarios.
Solution Approach 2:
The network indicator display is made dynamic by allowing the electronic device to switch between displaying LTE indicator, 5G indicator, or no indicator based on real-time network connection status, dual connectivity state, and operator policy restrictions. This dynamic adaptation resolves the contradiction by adjusting information display to actual network conditions.
2Productivity
If the electronic device always displays the 5G indicator to promote 5G network usage, then the network promotion effectiveness is improved, but the information accuracy deteriorates when 5G is not actually connected
Solution Approach 1:
The patent changes the display parameter (network indicator type) based on the actual network connection parameters. When dual connectivity with 5G is established, the 5G indicator is displayed; when only LTE is connected, the LTE indicator or no indicator is displayed. This parameter-based adaptation ensures both promotion effectiveness and accuracy.
Solution Approach 2:
The display system incorporates feedback from the network connection status and operator policy restrictions. The electronic device receives feedback about actual network connectivity and adjusts the indicator display accordingly, preventing inaccurate 5G promotion when 5G connection is not available.
3Adaptability or versatility
If the electronic device follows operator policies to restrict 5G indicator display, then the operator control is improved, but the user awareness of 5G capability deteriorates
Solution Approach 1:
The electronic device performs preliminary actions by checking operator policy restrictions before displaying the 5G indicator. When operator policies restrict 5G display, the device proactively adheres to these restrictions while still maintaining the capability to display 5G information when policies allow, thus balancing operator control with user awareness.
