5G Signal Display Stability During Dual-Connectivity Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unstable display of 5G signal due to changes in network environment during terminal movement in NSA/SA dual-mode 5G networks, leading to user dissatisfaction and impact on product quality and brand reputation.
Innovation Solution
Implementing a method with multiple timers and data radio bearer checks to determine the 5G signal type, including starting a first timer upon secondary cell group bearer release, querying data radio bearers and 5G cell information to ensure stable signal display.

Engineering Contradiction Analysis
1Quantity of substance
If RRC connection of LTE is released in ENDC network, then 4G network resource is freed, but 5G signal display becomes unstable and switches to 4G
Solution Approach 1:
The patent applies preliminary action by maintaining the 5G signal display state temporarily after RRC connection release, before actually switching to 4G display. The timer mechanism pre-prepares for the state transition by keeping the 5G indication active during the transition period, preventing premature display changes that would cause instability.
Solution Approach 2:
The patent implements dynamics by introducing a timer-based dynamic state transition mechanism. The display state is not fixed but transitions dynamically based on timer expiration and RRC connection state, allowing the system to adapt between 5G and 4G display states smoothly according to actual network conditions rather than rigidly following RRC connection state.
2Reliability
If timer duration is extended to maintain 5G display, then signal stability improves, but response time to actual network state changes increases
Solution Approach 1:
The patent applies periodic action through the timer mechanism that periodically checks and updates the display state based on RRC connection status. The timer creates regular evaluation intervals where the system reassesses whether to maintain 5G display or switch to 4G display, balancing stability with timely response to network changes.
Solution Approach 2:
The patent implements feedback by continuously monitoring RRC connection state and using this information to control the display state through the timer mechanism. The system receives feedback about actual network connectivity status and adjusts the display accordingly, ensuring the display reflects true network conditions while maintaining stability during transitions.

AI summary
A method for realizing stable display of a 5G signal includes when a master node is switched and a secondary cell group bearer is released in a dual-connectivity network, starting a first timer and displaying the 5G signal; when it is determined that the first timer expires and it is detected that a radio resource control is in an idle state, starting a second timer and displaying the 5G signal; when it is determined that the second timer expires and it is detected that the radio resource control is in a connected state, querying a number of data radio bearers and displaying a signal type according to the number of data radio bearers; and when it is detected that the radio resource control is in the idle state, querying an information database of a 5G cell and displaying the signal type according to information of the 5G cell.
