ANR Task Execution via Selective DRX Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Automatic Neighbor Relation (ANR) task execution in LTE networks has low efficiency and success rates due to the requirement for Long DRX ability, which affects user experience and Key Performance Indicators (KPI) when configuring DRX cycles for User Equipment (UE) exceed 1000 ms, impacting Quality of Service (QoS).
Innovation Solution
An ANR task execution method that selects and configures Discontinuous Reception (DRX) parameters specifically for user equipment based on the ANR function type, enabling intra-system or inter-system ANR operations, and manages these configurations through a user equipment selection module and DRX configuration module to optimize DRX parameter settings and timer management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DRX cycle is configured to be greater than 1000 ms to complete inter-system ANR measurement, then the ANR measurement can be completed, but the UE satisfaction of QoS is bad and the cell KPI index is influenced
Solution Approach 1:
The patent segments the ANR measurement process by identifying and selecting only those UEs that have both ANR measurement capability and Long DRX ability. This segmentation allows the system to apply extended DRX cycles specifically to this subset of UEs, rather than uniformly to all UEs, thus enabling ANR measurement completion while preserving QoS for other UEs.
Solution Approach 2:
The patent applies different DRX cycle configurations to different UEs based on their specific capabilities. UEs with Long DRX ability and ANR measurement capability are configured with extended DRX cycles (>1000ms), while other UEs maintain their standard DRX configurations. This local quality approach ensures that QoS is maintained for the majority of UEs while enabling ANR measurements for the specific subset that requires it.
2Reliability
If the DRX cycle is configured to be greater than 1000 ms for all UEs to enable inter-system ANR, then the ANR measurement can be completed, but the execution efficiency is low and the success rate is low
Solution Approach 1:
The patent segments the UE population into two groups: those with Long DRX ability and ANR measurement capability, and those without. By selecting only the first group for extended DRX configuration, the system avoids the inefficiency of applying extended cycles to all UEs, thereby maintaining higher execution efficiency while still enabling ANR measurements.
Solution Approach 2:
The patent leverages the inherent Long DRX ability of certain UEs to perform ANR measurements during their sleep state. These UEs self-configure with extended DRX cycles and autonomously perform the measurements, eliminating the need for system-wide configuration changes and improving overall execution efficiency.
3Reliability
If the DRX cycle is configured to be greater than 1000 ms for all UEs, then the inter-system ANR requirement can be met, but the entire user experience satisfaction of the cell is low
Solution Approach 1:
The patent applies extended DRX cycles only to specific UEs that have both ANR measurement capability and Long DRX ability, rather than to all UEs in the cell. This localized configuration ensures that the inter-system ANR requirement is met while minimizing the impact on overall user experience satisfaction, as the majority of UEs continue to operate with standard DRX configurations.

AI summary
An Automatic Neighbor Relation (ANR) task execution method, system and an ANR user equipment management method, apparatus are described, when an ANR function is enabled, a corresponding User Equipment (UE) is selected for the enabled ANR function, and then a Discontinuous Reception (DRX) configuration matching this ANR function is configured for the selected UE; that is, the disclosure specifically configures a matching DRX parameter for the UE selected by the ANR function, without searching a required UE from the UE configuring a Long DRX in an entire cell, thus improving efficiency and a success rate of executing an ANR task; simultaneously the disclosure only needs to perform specific configuration on the UE selected by the ANR function, without changing the configuration of all the UEs in the entire cell, thus greatly reducing an influence on a Key Performance Indicator (KPI) of the cell, and improving entire user experience satisfaction of the cell.
