Dynamic DRX Parameter Configuration for Power and Performance Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Long Term Evolution systems, Discontinuous Reception (DRX) parameters configured by the RRC layer face a challenge in balancing power-saving and performance requirements, as different terminals have varying demands, leading to suboptimal system performance due to fixed or inflexible DRX cycle configurations.
Innovation Solution
A method and device for dynamically configuring DRX parameters by adjusting the DRX cycle value with a configured step length, ensuring the terminal meets the Guaranteed Bit Rate (GBR) requirement, which involves calculating a new initial cycle value based on actual scheduling intervals and service types, allowing for real-time adaptation of power-saving and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a smaller DRX cycle is configured, then scheduling opportunities of terminal service in time domain are guaranteed, but power-saving ability is sacrificed
Solution Approach 1:
The patent applies dynamics by making the DRX cycle configurable and adjustable rather than fixed. The system allows dynamic modification of DRX cycle parameters through RRC layer signaling, enabling the network to adapt the cycle length based on service requirements and terminal state, thus resolving the contradiction between maintaining scheduling opportunities and achieving power-saving.
Solution Approach 2:
The patent employs parameter changes by allowing the DRX cycle duration to be modified through RRC reconfiguration. The network can adjust the drx-CycleLength parameter and other DRX-related parameters dynamically, transforming the static DRX configuration into a flexible one that can balance scheduling needs against power consumption based on current service conditions.
2Use of energy by moving object
If a larger DRX cycle is configured, then power-saving is improved, but time delay requirement of services is not met, decreasing system performance
Solution Approach 1:
The patent uses dynamics to allow the DRX cycle to be adjusted based on service characteristics and terminal activity. By making the cycle length adaptable rather than fixed, the system can extend the cycle for power-saving when services are delay-tolerant, and shorten it when time requirements are stringent, thus resolving the contradiction between power-saving and time delay requirements.
Solution Approach 2:
The patent applies parameter changes by enabling modification of DRX cycle parameters through RRC signaling. The network can change the drx-CycleLength and other parameters dynamically, allowing the system to optimize the balance between power consumption and service delay requirements based on actual network conditions and service priorities.
3Ease of manufacture
If fixed DRX parameters are configured by RRC layer, then configuration simplicity is maintained, but adaptability to different terminal service demands is reduced
Solution Approach 1:
The patent applies dynamics by transforming the static DRX parameter configuration into a dynamic one. Through RRC layer signaling, the system can reconfigure DRX parameters adaptively based on terminal service demands, terminal state, and network conditions, thus maintaining configuration simplicity while achieving high adaptability to different service requirements.
Solution Approach 2:
The patent employs universality by creating a unified RRC-based configuration mechanism that serves multiple functions: initial DRX parameter setup, adaptive adjustment based on service demands, and optimization for different terminal states. This multi-functional approach allows a single configuration system to handle diverse service requirements without sacrificing simplicity.

AI summary
The present invention provides a device and a method for dynamically configuring Discontinuous Reception parameters, and the method includes: when DRX parameters of a terminal need to be adjusted, the DRX parameters are adjusted until the terminal satisfies the requirement of the Guaranteed Bit Rate after the adjustment of DRX, and then the DRX parameters are no longer adjusted. Adopting the technical scheme of the present invention can make a base station adapt to the power-saving and performance requirement of the terminal in real time by a dynamic estimation of the DRX adjusted parameters of the terminal, in addition, it can also satisfy the requirement for the signaling load in different circumstances by configuring an adjusted cycle.
