Differentiated Network Slice Registration by UE Usage Reason
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks lack the ability to control and ensure proper utilization of network slices, as they cannot determine whether to allow or deny registration based on the actual need for network slice usage by user equipment.
Innovation Solution
Implementing a wireless communication device and network that allow the UE to transmit an indication of the reason for network slice registration, enabling the network to send identities of allowed slices, thereby controlling resource use and optimizing network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network allows unrestricted registration to network slices, then user equipment can access any network slice, but the network cannot control or ensure proper utilization of network slices
Solution Approach 1:
The patent implements a feedback mechanism where the UE indicates the reason for registration (actual usage vs. proactive) and the network responds by providing allowed NSSAIs based on this feedback. This enables the network to control slice registration based on actual usage patterns while maintaining user accessibility.
Solution Approach 2:
The patent changes the registration parameter from a simple binary allow/deny state to a differentiated state based on registration reason. The network distinguishes between actual usage scenarios and proactive registrations, adjusting the allowed NSSAIs accordingly. This parameter differentiation enables controlled access while ensuring proper utilization.
2Reliability
If the network implements control over network slice registration, then proper utilization can be ensured, but the complexity of the registration procedure increases
Solution Approach 1:
The patent implements self-service by having the UE autonomously determine and indicate the reason for registration based on its own usage patterns. The UE decides whether to register proactively or based on actual usage without requiring complex network-side analysis or manual configuration. This maintains control while reducing procedural complexity.
Solution Approach 2:
The patent segments the registration control into distinct scenarios: actual usage-based registration and proactive registration. Each scenario has specific handling rules, allowing the network to apply appropriate control measures selectively rather than implementing a monolithic complex system. The segmentation simplifies the overall control logic.
3Productivity
If the network restricts UE registration to necessary slices only, then network efficiency improves, but the ease of operation for user equipment decreases
Solution Approach 1:
The patent uses feedback to maintain ease of operation by having the UE automatically indicate its registration reason based on its operational state. The network responds with appropriate allowed NSSAIs, but the overall process remains automated and transparent to the user. This enables restricted registration while preserving operational simplicity.
Solution Approach 2:
The patent implements self-service where the UE autonomously determines its registration reason and communicates this to the network without user intervention. The UE monitors its own usage patterns and makes registration decisions automatically, maintaining ease of operation while enabling network efficiency through selective slice access.
