Edge Enabler Server Selection Across 5GC and EPC Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge computing systems fail to adapt to changes in wireless communication core network types, UE types, and radio access methods, leading to service disruptions and personal information infringement, without providing continuous services during UE movement between different networks.
Innovation Solution
A method and device for providing edge computing services based on UE type information, using a type allocation code instead of permanent equipment IDs, and recognizing UE movements between different radio access methods, enabling seamless service continuity across 5GC and EPC networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the edge computing system uses permanent equipment ID (PEI) to identify UEs, then the UE can be uniquely identified for service provision, but personal information infringement occurs due to user tracking
Solution Approach 1:
The patent extracts only the necessary identification capability from the PEI while removing the tracking functionality. It introduces a type allocation code that identifies UE type categories without containing unique user identifiers, thereby separating identification needs from personal information collection
Solution Approach 2:
The patent uses temporary, non-unique type allocation codes instead of permanent unique identifiers. These codes are assigned based on UE type and can be changed or reassigned without affecting the core service provision, making them disposable rather than permanent tracking identifiers
2Device complexity
If the edge computing system does not track UE movement between core networks, then system complexity is reduced, but service continuity cannot be ensured during network transitions
Solution Approach 1:
The patent performs preliminary registration of UE type information with the edge enabler server before actual service delivery. This advance registration ensures that when UE moves between core networks, the edge computing system already has the necessary type information to maintain service continuity without complex real-time tracking
Solution Approach 2:
The patent creates a universal type allocation code system that works across different core network types (5GC, EPC). This universal identifier enables the edge computing system to handle UEs regardless of which core network they are currently connected to, providing multi-network service continuity without complex network-specific tracking mechanisms
3Productivity
If the edge computing system provides specialized services based on UE type, then service quality is improved, but the system cannot obtain UE type information using existing methods
Solution Approach 1:
The patent implements preliminary collection and registration of UE type information during the initial connection phase. The UE provides its type information to the edge enabler server before service delivery begins, ensuring that specialized services can be configured and provided without losing critical UE type data
Solution Approach 2:
The patent introduces the edge enabler server as an intermediary that collects, stores, and manages UE type information. This intermediary component bridges the gap between UE identification needs and specialized service provision, maintaining UE type data without requiring direct access to sensitive UE identifiers
4Adaptability or versatility
If the mobile communication UE moves between different core networks, then network coverage and service availability are improved, but the changed core network may not support the previously available services
Solution Approach 1:
The patent implements a dynamic service adaptation mechanism where the edge enabler server continuously monitors core network type changes and adjusts service provision accordingly. When UE moves between 5GC and EPC networks, the system dynamically identifies the target network type and selects appropriate services that are compatible with the new network environment
Solution Approach 2:
The patent changes the service selection parameters based on core network type. Instead of using fixed service configurations, the system adjusts service parameters according to the detected core network type (5GC or EPC), ensuring that only services supported by the current network are provided, thereby maintaining reliability during network transitions

AI summary
According to one embodiment of the present disclosure, a method by which an edge enabler server (EES) of an edge computing system provides an edge computing service to user equipment (UE) comprises steps in which: the UE receives a registration message including available or currently connected core network (CN) type information or radio access technology (RAT) type information; a first network function (NF) device of a core network for providing the edge computing service to the UE is selected on the basis of the CN type information or the RAT type information; and a registration response message is transmitted to the UE, wherein, if the registration message includes the CN type information, one from among a first type for supporting a first CN, a second type for supporting a second CN, and a third type for supporting both the first CN and the second CN is indicated, and, if the registration message is the RAT type information, one from among a first type for supporting a first RAT, a second type for supporting a second RAT, and a third type for supporting both the first RAT and the second RAT can be indicated.
