Edge Enabler Server Mobility Sharing for Selective UE Location Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems lack a method to determine User Equipment (UE) mobility characteristics in Edge Data Networks (EDN), leading to unnecessary and continuous tracking of stationary UEs, which consumes resources and causes traffic overhead.
Innovation Solution
A method and system for sharing UE mobility characteristics in 3GPP Edge Applications and HTTP services by using an Edge Enabler Server (EES) to receive mobility indications from Edge Enabler Clients (EECs), determining mobility support, and selectively subscribing to 3GPP core network entities for location information based on UE mobility, reducing unnecessary location tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous location tracking is performed for all UEs in Edge Data Network, then service continuity is ensured for mobile UEs, but resource consumption and traffic overhead increase due to stationary UEs
Solution Approach 1:
The patent applies local quality by differentiating tracking strategies based on UE mobility characteristics. The Edge Enabler Server determines whether a UE is stationary or mobile and applies appropriate tracking methods: for stationary UEs, no continuous tracking is performed; for mobile UEs, continuous location tracking is performed to ensure service continuity. This localized differentiation resolves the contradiction by avoiding unnecessary resource consumption on stationary UEs while maintaining service continuity for mobile UEs.
Solution Approach 2:
The patent changes the parameter of tracking behavior based on UE mobility state. By determining mobility characteristics (stationary vs. mobile) and adjusting tracking parameters accordingly, the system transitions from uniform continuous tracking to conditional tracking. This parameter change allows the system to maintain service continuity for mobile UEs while reducing resource consumption for stationary UEs.
2Reliability
If continuous location tracking is performed for all UEs, then mobile UEs maintain service continuity, but traffic overhead increases due to unnecessary tracking of stationary UEs
Solution Approach 1:
The patent applies local quality by differentiating tracking strategies based on UE mobility characteristics. The Edge Enabler Server determines whether a UE is stationary or mobile and applies appropriate tracking methods: for stationary UEs, no continuous tracking is performed; for mobile UEs, continuous location tracking is performed to ensure service continuity. This localized differentiation resolves the contradiction by avoiding unnecessary resource consumption on stationary UEs while maintaining service continuity for mobile UEs.
Solution Approach 2:
The patent extracts the unnecessary tracking function for stationary UEs from the overall location tracking system. By identifying and separating stationary UEs from mobile UEs, the system removes the harmful element (continuous tracking of stationary UEs) that causes traffic overhead, while preserving the useful function (continuous tracking of mobile UEs for service continuity).

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method to share UE mobility characteristics in an edge network (1000) by an EES (200). The method includes receiving an EEC registration request message comprising a mobility indication from an EEC device (1000). Further, the method includes determining whether the mobility indication indicates whether the EEC device supports mobility. Further, the method includes performing subscribing to a 3GPP core network entity for UE location information when the mobility indication indicates that the EEC device supports mobility, storing the location information in an EEC context, and sending an EEC registration response message to the EEC device. In another embodiment, the method includes performing one-time location fetch for the EEC when the mobility indication indicates that the EEC device does not support mobility, storing the location information in a memory of the EES, and sending an EEC registration response message to the EEC device.
