MDAS-Assisted Paging for Out-of-Coverage UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, when User Equipment (UE) goes out-of-coverage (OOC), repetitive paging attempts by the network result in wastage of resources due to failed paging initiation by the Access and Mobility Management Function (AMF), which continues until UE re-enters coverage.
Innovation Solution
Implement Management Data Analytics Service (MDAS) assisted paging by generating a Paging Analytics Report (PAR) that includes information on UE's out-of-coverage duration and location, allowing the AMF to intelligently decide when and where to initiate paging, optimizing network resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repetitive paging attempts are made by the AMF when UE is out of coverage, then the network continues to attempt paging until UE re-enters coverage, but this results in wastage of network resources
Solution Approach 1:
The network performs preliminary actions by requesting and obtaining UE mobility information and coverage status from the data analytics function before initiating paging attempts. This advance knowledge allows the AMF to determine whether the UE is in coverage or out of coverage before paging, preventing wasteful repetitive paging attempts and optimizing network resource usage while maintaining reliable paging delivery
Solution Approach 2:
The data analytics function provides feedback to the AMF regarding UE coverage status and mobility information. This feedback mechanism enables the AMF to make informed decisions about whether to initiate paging attempts, allowing the system to adapt paging behavior based on real-time UE status information and avoid unnecessary resource consumption
2Productivity
If the AMF initiates paging without checking UE coverage status, then paging can be attempted immediately, but paging attempts fail when UE is out of coverage
Solution Approach 1:
The system performs preliminary checks by requesting UE mobility information and coverage status from the data analytics function before the AMF initiates paging. This preliminary action ensures that paging attempts are only made when UE is in coverage, maintaining high paging initiation speed while eliminating failed attempts due to out-of-coverage conditions
Solution Approach 2:
The data analytics function acts as an intermediary between the AMF and UE coverage status information. It collects, processes, and provides relevant mobility and coverage information to the AMF, enabling the AMF to make rapid informed decisions about paging initiation without directly querying UE status, thus maintaining fast paging initiation while ensuring high success rates
