RRC Message Reordering Circuit for Wireless UE Priority Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional mobile communication systems, wireless user equipment (UE) frequently transmits measurement reports to adjust radio resources, but the network's delayed response often results in unsuitable resource configurations due to UE movement, leading to connection losses or call drops.
Innovation Solution
A control circuit in the wireless UE dynamically rearranges the transmission order of RRC messages based on priority, ensuring that higher-priority messages are transmitted first, and replaces older messages with newer ones to maintain alignment with the current signal environment, thereby optimizing radio resource configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless UE frequently transmits measurement reports to adjust radio resources, then the radio resource configuration can be updated more often, but the network's delayed response causes the configuration to become unsuitable due to UE movement, leading to connection losses or call drops
Solution Approach 1:
The patent implements dynamic message replacement in the message queue, where newer measurement reports can replace older pending reports based on priority and timing criteria. This dynamic adjustment allows the system to adapt to changing network conditions and UE movement, ensuring that the most current measurement data is used for resource configuration decisions, thereby maintaining connection stability while enabling frequent updates.
2Loss of time
If the network side takes time to handle measurement reports, then processing can be thorough, but the UE may move to other places during this handling time, resulting in outdated configuration
Solution Approach 1:
The patent applies preliminary action by preparing and queuing measurement reports with priority markings before network processing completes. The message queue system pre-organizes reports so that when processing is complete, the most relevant and current reports are ready for immediate configuration updates, reducing the effective time lag between measurement and configuration adjustment.
Solution Approach 2:
The system implements feedback mechanisms where the network side continuously monitors UE movement and message queue status, adjusting processing priorities based on current conditions. This feedback loop ensures that processing thoroughness is maintained while adapting to real-time changes in UE position and network state, preventing outdated configurations.
3Quantity of substance
If multiple measurement reports are queued for transmission, then comprehensive data can be sent, but the transmission order may not reflect the current urgency or relevance of each report
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different measurement reports based on their specific characteristics, such as urgency, relevance to current UE position, and importance for network decisions. This differentiated priority marking within the message queue allows each report to be processed according to its specific needs rather than a uniform first-come-first-served approach, optimizing the transmission order for current network conditions.

AI summary
A control circuit of a wireless user equipment includes: a message generating circuit for generating a first and a second RRC (radio resource control) messages, and configuring corresponding first and second priorities; a message reordering circuit for comparing the first and second priorities. If the first priority is higher than the second priority, the message reordering circuit assigns the second RRC message in a message queue to have a transmission order after the first RRC message. Afterward, when the message generating circuit generates a third RRC message, the message generating circuit configures a third priority for the third RRC message. The message reordering circuit compares the first through the third priorities to rearrange transmission orders of RRC messages, and if the third priority is equal to the second priority, the message reordering circuit replaces the second RRC message in the message queue with the third RRC message.
