HSS Mobility Timer Configuration for UE Connectivity Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for configuring and updating monitoring events for user equipment (UE) in 5G communication systems, particularly in scenarios involving loss of connectivity, which affects service quality and subscriber information management.
Innovation Solution
A method and apparatus where a Home Subscriber Server (HSS) receives monitoring event information from a Service Capability Exposure Function (SCEF), sets a mobility-related timer based on a maximum detection time, and transmits this information to a mobility management entity, enabling effective UE monitoring and subscriber information updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the HSS sets the mobility-related timer based on maximum detection time from external server requests, then the service quality and monitoring accuracy are improved, but the system complexity and configuration management burden increase
Solution Approach 1:
The HSS acts as an intermediary between the external server and the MME, translating the maximum detection time parameter into appropriate mobility-related timer values. This mediator role allows the system to maintain monitoring accuracy without increasing complexity at the MME or external server sides, as the HSS handles the parameter conversion and coordination centrally
Solution Approach 2:
The system transforms the maximum detection time parameter received from external servers into standardized mobility-related timer configurations. By changing and adapting parameters at the HSS level, the system achieves precise monitoring control while maintaining compatibility with existing network elements and avoiding complexity proliferation across the network
2Adaptability or versatility
If the HSS receives and processes monitoring event information from SCEF for each UE, then the service management capability is improved, but the processing time and signaling overhead increase
Solution Approach 1:
The HSS pre-configures mobility-related timer values and monitoring parameters based on maximum detection time requirements before actual UE monitoring events occur. This preliminary configuration approach allows the system to handle multiple UE monitoring requests efficiently without processing delays, as the timer settings are prepared in advance and can be quickly applied when needed
Solution Approach 2:
The HSS implements a universal monitoring configuration mechanism that handles multiple types of UE monitoring events through a single standardized process. By making the HSS multi-functional in handling different monitoring scenarios (loss of connectivity, mobility events, etc.), the system improves service management capability while avoiding the need for separate processing paths that would increase overall processing time

AI summary
A method and an apparatus for configuring a function of monitoring events concerning user equipment (UE) are provided. The method of a home subscriber server (HSS) includes receiving a first request message including monitoring event information from a service capability exposure function (SCEF), setting, if the monitoring event information is set to loss of connectivity, a mobility-related timer of a terminal to a value based on a value of a maximum detection time included in the first request message, and transmitting a second request message including the monitoring event information and the set mobility-related timer of the terminal to a mobility management entity.
