Core Network Server Selection for Immersive Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networks fail to efficiently handle the stringent requirements of immersive services like augmented reality and ultra-high-definition 3D video due to inadequate bandwidth and delay management, leading to suboptimal user experiences.
Innovation Solution
The system optimizes mobile traffic flow by enabling the core network to inform application servers about changes in user equipment contact information and selecting the best user-plane path and server location based on factors such as location, load, and mobility, using network functions like UE Information Request and SCS/AS Relocation Request messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the core network independently selects the user-plane path to optimize bandwidth, then bandwidth efficiency is improved, but the application server cannot be optimally selected based on location and delay requirements
Solution Approach 1:
The patent merges the user-plane path selection function with the application server selection function into a unified joint optimization process. The core network and application server work together to simultaneously select both the optimal user-plane path and the optimal application server based on combined criteria including location, delay requirements, and bandwidth efficiency, rather than independently optimizing each function.
Solution Approach 2:
The patent implements a feedback mechanism where the core network provides information about the selected user-plane path and application server to the application server, which then uses this feedback to adjust its server selection decisions. This iterative feedback loop ensures that both path selection and server selection are optimized based on real-time network conditions and service requirements.
2Reliability
If the application server independently selects the server location, then service optimization is improved, but the user-plane path cannot be optimized based on real-time location changes
Solution Approach 1:
The patent implements preliminary action by having the core network proactively monitor user equipment location changes and pre-select optimal user-plane paths before the application server needs to respond. When location changes are detected, the core network has already prepared alternative paths, enabling rapid switchover without waiting for the application server to process location change notifications.
3Adaptability or versatility
If the end-to-end path is divided into independent user-plane and external path, then network flexibility is improved, but coordination between core network and application server becomes complex
Solution Approach 1:
The patent introduces a joint selection mechanism as an intermediary that coordinates between the core network and application server. This intermediary layer simplifies the coordination complexity by providing a standardized interface and decision-making framework that automatically aligns user-plane path selection with application server selection, reducing manual coordination requirements while maintaining network flexibility.

AI summary
The present application is at least directed a system for managing a server transition associated with user equipment. The system includes a non-transitory memory and a processor that is operably coupled to the non-transitory memory. The processor is configured to perform the instructions of receiving a relocation request from a first server to switch to another server. The processor is also configured to verify credentials of the first server. The processor also determines whether a first core networking terminating point associated with the first server is appropriate for the other server to communicate with the user equipment. Further, the processor sends a result of the determination to the user equipment.
