Dynamic Network Slice Allocation for Service Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slice allocation methods fail to dynamically adjust services and slices in response to changing service requirements and resource status, leading to inefficient resource utilization and potential service mismatches.
Innovation Solution
A method that involves a first apparatus storing correspondence information associating services with slices and determining suitable slices based on service requirements, allowing for reallocation of services to slices that meet changing requirements, and notifying users of connection destination changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If services are uniquely allocated to slices in advance, then service allocation is simple and stable, but the system cannot adapt to dynamically changed service requirements or resource status
Solution Approach 1:
The patent implements dynamic slice allocation by enabling services to be reallocated to different slices based on changing service requirements and resource status. The system transitions from static pre-allocation to dynamic reallocation, where the network manager continuously monitors and adjusts slice assignments to match current service needs and available resources.
Solution Approach 2:
The patent employs feedback mechanisms where the network manager receives information about service requirements and resource status, processes this information, and makes reallocation decisions. The system continuously monitors the state of services and slices, and adjusts allocations based on this feedback to maintain optimal matching between service needs and slice capabilities.
2Productivity
If services are dynamically reallocated to slices, then resource utilization is optimized and service requirements are better met, but the allocation management becomes more complex
Solution Approach 1:
The patent creates a universal network manager that handles multiple functions including monitoring service requirements, assessing resource status, determining allocation decisions, and managing slice assignments. This multi-functional approach consolidates complex allocation management into a single system that can adapt to various service types and resource conditions using the same framework.
3Reliability
If fixed slice allocation is used, then system stability is maintained, but resource optimization and adaptability to changing conditions are reduced
Solution Approach 1:
The patent enables the slice allocation system to self-adjust by automatically monitoring service requirements and resource status, and making reallocation decisions without external intervention. The network manager autonomously determines when reallocation is needed and executes the reallocation, allowing the system to maintain reliability while adapting to changing conditions through self-service mechanisms.

AI summary
In a service mapping apparatus (10), an allocation service table, which associates a service to which a slice is allocated in advance, the slice, and an address representing an apparatus executing the service with each other, is stored. In addition, a request accepting unit (11) of the service mapping apparatus (10) receives an SLA-SL that is a requirement of a function. A determination unit (15) determines a slice including an SLA-SL corresponding to the received service requirement (SLA-SL) of the service (satisfying the service requirement). In a case in which a service that is the allocation target is associated with a slice in advance, an allocation unit (16) changes allocation of the service to the determined slice.
