Cellular Network Slicing for Location- and Time-Aware QoS
Solution Overview
Problem
Existing cellular network capacity allocation methods do not accurately account for varying network loads by location and time, leading to suboptimal service provision for clients with specific quality of service (QoS) requirements.
Innovation Solution
A cellular network management system (CLAMS) collects performance data to create a network model, analyzes service requests, and configures network resources to offer customized access conditions packages that match QoS parameters and client needs, considering location, time, and resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard set of terms is provided to clients defining conditions of access, then network access can be granted simply, but the allocation does not optimize for varying network loads by location and time
Solution Approach 1:
The patent segments the cellular network into multiple network slices, each dedicated to specific services or clients with particular QoS requirements. This segmentation allows the network to allocate resources more efficiently by creating specialized access conditions for different slices rather than using a single standard access policy for all clients.
Solution Approach 2:
The system dynamically adjusts access conditions based on real-time network load, location, and time. The network management system continuously monitors network state and modifies access conditions packages accordingly, transitioning from static standard terms to dynamic, context-aware access policies that optimize resource utilization while maintaining ease of operation.
2Ease of manufacture
If network access is granted based on standard terms without considering location and time, then provisioning is straightforward, but QoS requirements cannot be accurately met
Solution Approach 1:
The patent implements local quality by creating access conditions that are specific to particular locations, time periods, and network slices. Each network slice receives customized access conditions tailored to its specific QoS requirements, rather than applying uniform standard terms across the entire network. This ensures reliable QoS satisfaction while maintaining relatively simple implementation through automated policy generation.
3Productivity
If the network creates customized access conditions for each client based on real-time analysis, then QoS optimization is improved, but system complexity increases
Solution Approach 1:
The network management system automatically generates access conditions packages by analyzing network state and client requirements without manual intervention. The system serves itself by autonomously creating, updating, and managing customized access conditions for multiple network slices, reducing the operational complexity despite the sophistication of the customization logic.
Solution Approach 2:
The patent implements a universal network management system that handles multiple functions: monitoring network state, analyzing client requirements, generating access conditions, and managing multiple network slices simultaneously. This multi-functional approach consolidates complexity into a single system rather than requiring separate mechanisms for each function.
4Extent of automation
If the network uses fixed access terms, then management is simple, but adaptability to different client needs and network conditions is reduced
Solution Approach 1:
The system transitions from static access terms to dynamic access conditions that automatically adapt to changing network conditions, client requirements, and service demands. The network management system continuously updates access conditions packages based on real-time analysis, maintaining high automation while achieving versatile adaptation to different scenarios.

AI summary
Various arrangements for managing cellular network slicing are detailed. A cellular network management system may obtain performance data from cellular network components of a cellular network over time. The cellular network management system may analyze the performance data from the plurality of cellular network components to create a cellular network model indicative of performance of discrete portions of the cellular network over time. A service request may be received from an external entity that defines quality of service (QoS) parameters. A cellular network access conditions package may be created that defines conditions under which the external entity is eligible to utilize the cellular network. Cellular network components may then be configured to permit access to the cellular network by user equipment (UE) of the external entity and data services may be provided to the UE.
