User-Driven Network Slice Handover for Session Requirement Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks lack visibility into user device session requirements, leading to misalignment between network slice capabilities and user device needs, which degrades user experience and wastes resources.
Innovation Solution
User devices monitor for slice handover requirements and select a new network slice based on session needs, initiating a handover request to align capabilities with application demands, including billing information for on-demand use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the core network assigns network slices based on initial session type and subscription, then network slice assignment is automated and efficient, but the network slice capabilities may not align with changing user device session requirements
Solution Approach 1:
The user device autonomously monitors its own session requirements and initiates slice handover requests when misalignment is detected, without requiring continuous network intervention. The device compares its current session needs against the capabilities of its assigned network slice and self-determines when handover is necessary.
Solution Approach 2:
The system implements a feedback loop where the user device continuously monitors session requirements and network slice capabilities, detects misalignment conditions, and triggers handover requests. The network acknowledges and executes these requests, creating a closed-loop system that adapts to changing requirements.
2Device complexity
If the network maintains fixed network slice assignments, then network resource management is simplified, but user experience degrades when session requirements change
Solution Approach 1:
The network slice assignment transitions from a static, fixed state to a dynamic state where the user device can initiate handovers based on real-time session requirements. The system allows flexible reassignment while maintaining simplified network-side management through user-triggered requests.
Solution Approach 2:
The user device proactively monitors session requirements and detects misalignment conditions before they significantly impact user experience. By initiating handover requests in advance, the system prevents service degradation rather than reacting to it.
3Device complexity
If the network lacks visibility into user device session requirements, then network monitoring is simpler, but network slice capability alignment with user needs cannot be ensured
Solution Approach 1:
Instead of the network monitoring and inferring user session requirements, the inversion shifts the monitoring responsibility to the user device itself. The device monitors its own session needs and uses this information to make informed handover decisions, eliminating the need for complex network-side monitoring while preserving critical information.
Data Source
AI summary
Various embodiments include a user device that comprises processing circuitry and radio circuitry. The processing circuitry detects a slice handover requirement. The processing circuitry selects a network slice based at least on session requirements in response to the slice handover requirement. The radio circuitry wirelessly transfers a slice handover request that identifies the network slice to a wireless communication network. The wireless communication network performs a slice handover from a serving network slice to the network slice indicated in the slice handover request.
