On-Demand Super Slice Instantiation for 5G Network Resource Orchestration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G and next-generation wireless communication networks, network slices often face challenges in accommodating additional resources required for specific services, such as high-capacity or performance demands, which exceed the capabilities of standard network slices, leading to inefficiencies and potential service disruptions.
Innovation Solution
The introduction of on-demand super slices, which can be dynamically instantiated and orchestrated to provide additional resources, allowing for the allocation of extra capacity and specialized services when needed, leveraging existing underutilized resources and managed by a gateway device to ensure efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slices are implemented to handle dedicated services, then service specialization and quality of service are improved, but network flexibility and adaptability to dynamic resource demands deteriorate
Solution Approach 1:
The patent implements dynamic network slicing where slice configurations can be modified, expanded, or contracted based on real-time service demands. The network management system allows for dynamic resource allocation and slice reconfiguration without requiring complete slice redesign, enabling both service specialization and adaptive response to changing conditions.
Solution Approach 2:
The patent segments the network into multiple virtual slices that can be independently managed and configured. Each slice can be customized for specific service requirements while the overall network maintains flexibility through the modular slice architecture, allowing individual slices to be adjusted without affecting others.
2Productivity
If additional resources are allocated to meet high-capacity service demands, then service performance is improved, but network resource efficiency and cost-effectiveness deteriorate
Solution Approach 1:
The patent employs dynamic resource allocation within network slices, where resources are allocated based on real-time service demands rather than static provisioning. This allows the network to optimize resource utilization by allocating additional capacity only when and where needed, improving service performance without permanently committing excess resources that would reduce overall network efficiency.
Solution Approach 2:
The patent changes network parameters dynamically to match service demands. Network slice characteristics such as bandwidth, processing capacity, and resource allocation parameters can be adjusted on-demand, allowing the system to provide high performance when needed while maintaining resource efficiency during normal operation through parameter optimization.
3Ease of operation
If standard network slices are used for all services, then network simplicity and ease of management are maintained, but service-specific performance and specialized capabilities deteriorate
Solution Approach 1:
The patent implements a universal network slice framework that can accommodate multiple service types through a common architecture. The standardized slice management system provides ease of operation while the flexible configuration capabilities allow each slice to be customized for specific service requirements, achieving both simplicity and service-specific performance through multi-functional design.
4Adaptability or versatility
If network slices are dynamically reconfigured to meet changing demands, then network adaptability is improved, but system complexity and orchestration difficulty increase
Solution Approach 1:
The patent introduces a network slice management system that acts as an intermediary between service demands and network resources. This intermediary handles the complexity of dynamic reconfiguration automatically, providing adaptability through automated slice management while shielding the overall system from excessive complexity through centralized orchestration and standardized interfaces.

AI summary
The provision of additional network resources (e.g., in the form of a dedicated super slice), can be requested on demand a per needed basis when higher capacity or performance is requested to facilitate the delivery of a service, when the delivery of the service cannot be met by a network slice associated with the service. A request for using a super slice can be sent to a management gateway device (mGW). The mGW can send the request for authorization to access the additional resources to a management device that manages the additional resources. Authorization can be granted for the additional resources to be used to facilitate or enable tasks that allow for continued delivery of that service.
