Shareable Network Slice Instance Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing technologies in virtual telecommunications networks face limitations in dynamically adjusting resources to accommodate additional similar services without terminating existing network slice instances (NSIs), leading to inefficiencies in resource utilization and service expansion.
Innovation Solution
A method that allows for the addition of new services to an existing shareable NSI without terminating it, by modifying the NSI to include new services and adjusting resource allocations, enabling multiplexing gains and efficient resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new NSI is created for each additional VN service, then service capability is ensured, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges multiple similar VN services into a single shareable NSI. When a new service request arrives, the system checks if an existing NSI can accommodate it, and if so, adds the service to the existing NSI rather than creating a new instance. This combining approach maintains service capability while improving resource utilization by eliminating redundant NSIs.
Solution Approach 2:
The patent makes NSIs multi-functional by enabling them to serve multiple VN services simultaneously. A single NSI is designed to be universal and can be shared across different services that have similar resource requirements, thereby reducing the total number of NSIs needed and improving overall resource efficiency.
2Loss of energy
If network resources are virtualized and shared, then resource utilization improves, but service isolation and reliability may deteriorate
Solution Approach 1:
The patent segments services into categories based on their resource requirements and characteristics. Services with similar profiles are grouped together and can share the same NSI, while maintaining logical isolation through service-specific configurations and resource allocation policies within the shared NSI.
Solution Approach 2:
The patent applies local quality by allowing different services within a shared NSI to have service-specific resource allocations, priority levels, and configuration parameters. Each service maintains its own service level agreement (SLA) and quality of service (QoS) parameters, ensuring that while resources are shared, each service receives appropriate isolation and reliability guarantees tailored to its specific needs.

AI summary
A method for providing a service in a telecommunications network comprising a plurality of resources and at least one slice of resources. The method comprises actions of receiving, creating and modifying. A request is received from a customer to serve a group of user devices by a first service. A new NSI is created to provide the first service, if it is determined that there is no existing NSI, shareable between a plurality of services, that can provide the first service. An existing NSI, shareable between a plurality of services, is modified to serve the group of user devices by that first service in addition to at least one second service that is already provided by the existing NSI, if it is determined that the existing NSI can provide the first service.
