DRX Timer Coordination in Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, conflicts between different Discontinuous Reception (DRX) configurations can cause terminals to enter dormancy or wake up prematurely, leading to data loss due to overlapping or conflicting timer settings.
Innovation Solution
A method and apparatus for controlling timers in terminals, where the operation of a first DRX configuration is determined based on the running state of a second DRX configuration, ensuring that timers are started or restarted according to existing timing parameters to avoid conflicts and maintain data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple DRX configurations are used independently, then each configuration can operate autonomously, but timer conflicts occur causing premature dormancy or wake-up
Solution Approach 1:
The patent merges multiple DRX timer operations into a unified timer management mechanism. When multiple DRX configurations are active, their timer operations are coordinated through a common control logic that checks timer running states across configurations, preventing conflicting operations while maintaining the independence of each DRX configuration's functional requirements.
2Speed
If timer operations are performed without checking running state, then response speed is fast, but data loss occurs due to conflicting timer operations
Solution Approach 1:
The patent implements preliminary checking of timer running states before executing timer operations. The control logic first determines whether a timer is currently running in any DRX configuration, and only proceeds with timer start/restart operations when safe to do so. This preliminary check prevents conflicting operations that would cause data loss, while maintaining efficient response through optimized check conditions.
3Reliability
If timer conflicts are resolved by sequential checking, then data integrity is maintained, but processing complexity increases
Solution Approach 1:
The patent creates a universal timer control mechanism that serves multiple DRX configurations simultaneously. A single control logic module handles timer operations for all configurations by checking a unified timer state, eliminating the need for separate checking logic for each configuration. This multi-functional approach maintains data integrity while reducing overall system complexity.

AI summary
A method for controlling a timer, performed by a terminal, includes: in response to determining that a timer of a first discontinuous reception (DRX) configuration among a plurality of DRX configurations in the terminal is to be started, determining an operation on the timer of the first DRX configuration according to a running state of a timer of a second DRX configuration among the plurality of DRX configurations.
