Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high traffic areas, existing radio communication systems face challenges in synchronizing radio configuration parameters between user equipment and small cells, leading to potential communication failures due to the use of outdated parameters after reconfiguration or modification.
Innovation Solution
A method for synchronizing radio configuration parameters between user equipment and dual-connected nodes in a radio communication system, involving the transmission of updated parameters from the secondary node to the user equipment, with the option to apply these parameters after a random-access procedure, allowing for continuous data communication on unmodified bearers during parameter synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio configuration parameters are updated in dual connectivity systems, then communication reliability is improved, but synchronization complexity increases
Solution Approach 1:
The patent introduces a synchronization indicator as an intermediary mechanism between the secondary node and user equipment. This indicator explicitly signals whether parameter synchronization is required, simplifying the coordination process. The indicator acts as a mediator that carries synchronization state information without requiring complex negotiation protocols between nodes and equipment.
Solution Approach 2:
The patent implements preliminary synchronization checks before parameter updates are applied. The synchronization indicator is prepared and transmitted in advance to indicate whether synchronization is needed, allowing the system to proactively manage parameter consistency rather than reacting to synchronization issues after they occur.
2Stability of the object's composition
If parameter synchronization is performed frequently, then parameter consistency is improved, but signaling overhead increases
Solution Approach 1:
The patent changes the state representation of synchronization status using a compact indicator parameter. Instead of transmitting full parameter sets or complex synchronization commands, the system uses a simplified indicator that changes state to reflect synchronization requirements, reducing the amount of signaling data transmitted while maintaining consistency information.
Solution Approach 2:
The patent extracts only the essential synchronization state information from the full parameter set and transmits it via the synchronization indicator. This extraction approach separates the critical synchronization status from the complete parameter configuration, allowing efficient signaling that conveys only the necessary information for maintaining parameter consistency.
3Productivity
If updated parameters are applied immediately, then communication efficiency is improved, but risk of using outdated parameters increases
Solution Approach 1:
The patent implements a feedback mechanism where the synchronization indicator provides real-time information about parameter synchronization status. This feedback allows the system to make informed decisions about when to apply updated parameters, ensuring that parameter updates occur only when synchronization is confirmed, thus maintaining both efficiency and reliability.
Solution Approach 2:
The system performs preliminary verification of synchronization status through the indicator before applying updated parameters. This preliminary check ensures that parameters are only applied when they are valid and synchronized, preventing the use of outdated parameters while maintaining communication efficiency by avoiding unnecessary delays.

AI summary
A method, in a radio communication system, for synchronising radio configuration parameters between user equipment in dual connectivity using a first set of parameters with a primary node and a secondary node of the system, comprising: transmitting a set of radio configuration parameters from the secondary node to the UE; transmitting a synchronisation request from the user equipment to the secondary node for the set of updated parameters; and applying the set of updated parameters, if any.
