Target Node Signaling for Flexible 5G Context Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing context relocation decisions for terminal devices during handover procedures, particularly in 5G networks, due to lack of flexibility and control over context relocation preferences and requirements.
Innovation Solution
An apparatus comprising a processor and memory that enables a target node to signal context relocation preferences or requirements to an anchor node, allowing for flexible decision-making based on load, radio conditions, and data availability, using existing or new Xn-AP messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the target node has full control over context relocation decisions, then the flexibility and efficiency of handover processes is improved, but the device complexity and control overhead increases
Solution Approach 1:
The patent implements dynamic context relocation control where the target node can adaptively signal its preferences and requirements based on real-time network conditions, terminal device states, and load situations. This allows the system to optimize handover decisions dynamically while maintaining manageable complexity through standardized signaling procedures.
Solution Approach 2:
The patent introduces configurable parameters and indicators that allow the target node to express different levels of context relocation preference (e.g., preferred, not preferred, mandatory). By changing these parameters based on network conditions, the system achieves flexibility without requiring complete redesign of the control architecture.
2Adaptability or versatility
If context relocation is performed frequently to optimize network performance, then the adaptability to changing conditions is improved, but the loss of time and signaling overhead increases
Solution Approach 1:
The patent enables the target node to signal its context relocation preferences in advance, before actual handover execution is required. This preliminary signaling allows the anchor node to prepare context relocation decisions proactively, reducing the time required during actual handover events while maintaining adaptability to changing conditions.
Solution Approach 2:
The patent implements a feedback mechanism where the target node provides information about its context relocation preferences and requirements back to the anchor node. This feedback loop enables optimized handover decisions without requiring frequent complete re-negotiations, thereby reducing signaling overhead while maintaining adaptability.
