T302 Timer Control During Cell Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a solution for controlling the T302 timer behavior during cell changes, such as handovers or RAN area updates, which affects Radio Resource Control (RRC) connection efficiency and network burden.
Innovation Solution
The method involves stopping or maintaining the T302 timer based on commands received from a network side device during cell changes, allowing the terminal to continue attempting RRC connections and reducing network processing burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the T302 timer is maintained during cell change, then the network processing burden is reduced, but the RRC connection efficiency deteriorates due to connection attempts being blocked
Solution Approach 1:
The patent applies dynamics by making the T302 timer behavior adaptive rather than static. The timer is dynamically stopped or maintained based on the cell change type (intra-NR vs. inter-RAT) and network commands, allowing the system to optimize between connection efficiency and network burden reduction in different scenarios.
Solution Approach 2:
The patent changes the timer state parameter based on different conditions. When cell change occurs, the T302 timer parameter is modified from 'maintained' to 'stopped' based on the specific scenario, enabling flexible control over connection attempt behavior and resolving the contradiction between efficiency and burden reduction.
2Productivity
If the T302 timer is stopped during cell change, then the RRC connection efficiency is improved, but the network processing burden increases due to additional connection attempts
Solution Approach 1:
The patent applies local quality by differentiating timer behavior based on the specific cell change scenario. Intra-NR cell changes may stop the timer to improve efficiency, while inter-RAT changes may maintain it to reduce burden. This localized approach allows optimal behavior for each specific case rather than a uniform approach.
Solution Approach 2:
The patent implements feedback mechanisms where the network side device provides commands to the terminal regarding timer behavior. The network receives feedback about cell change events and responds with appropriate timer control commands, enabling coordinated optimization of connection efficiency and network burden management.
3Productivity
If the terminal continuously attempts RRC connection during T302 timer running, then the connection efficiency is improved, but the network load increases
Solution Approach 1:
The patent applies preliminary anti-action by proactively stopping the T302 timer when certain cell change conditions are detected, before excessive connection attempts can occur. This preventive measure blocks potential harmful connection attempts in advance, reducing network load while maintaining necessary connection efficiency.
