DRX Active Period Starting Point Configuration for Resource Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the overlapping of active periods for multiple user equipment (UEs) in Discontinuous Reception (DRX) mode leads to uneven utilization of radio resources, resulting in reduced system capacity and potential degradation of Quality of Service (QoS), especially for delay-sensitive services like Voice over IP (VoIP).
Innovation Solution
The active period starting points for UEs are randomly set based on predetermined parameters, ensuring that these periods are distributed evenly in time, thereby avoiding resource inefficiencies and prioritizing high-priority services, which are calculated and configured by both the base station and the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If active period starting points for multiple UEs are set using fixed predetermined parameters, then the UE operation is simple and deterministic, but the active periods overlap frequently leading to uneven resource utilization and reduced system capacity
Solution Approach 1:
The patent applies dynamics by making the active period starting point configurable and adjustable based on system conditions. The base station can dynamically set different starting points for different UEs rather than using fixed predetermined values, allowing the system to adapt to varying traffic patterns and UE requirements, thereby improving resource utilization and system capacity
Solution Approach 2:
The patent changes the parameter of active period starting point from fixed to variable. By allowing the base station to configure different starting point values for different UEs based on their service requirements and system load, the system achieves better resource distribution and avoids the overlap problems caused by fixed parameter settings
2Productivity
If active periods for multiple UEs are concentrated in the same time slots, then the UE can efficiently receive data during active periods, but the radio resources are unevenly utilized and system capacity is reduced
Solution Approach 1:
The patent applies local quality by assigning different active period starting points to different UEs based on their individual characteristics and service requirements. This localized customization ensures that each UE receives appropriate resource allocation, improving both resource utilization efficiency and QoS for delay-sensitive services like VoIP
Solution Approach 2:
The base station performs preliminary action by calculating and configuring the active period starting points for UEs in advance, considering their service requirements and system conditions. This proactive configuration prevents resource conflicts and ensures QoS for delay-sensitive services before the actual data transmission occurs

AI summary
The present invention has disclosed a method for setting an active period starting point for a User Equipment (UE) in a Discontinuous Reception (DRX) mode, comprising steps of: a base station calculating and storing a position of the active period starting point for the UE based on predetermined parameters, so as to transmit data to the UE in a corresponding active period; the UE receiving Radio Resource Control (RRC) configuration information from the base station, and detecting whether the DRX mode is configured in it or not; the UE calculating its active period starting point based on predetermined DRX parameters in the received RRC configuration information; and the UE starting DRX based on the calculated active period starting point. The present invention has also disclosed an apparatus for setting an active period starting point for a UE in a DRX mode.
