Service Allocation Determination Device Optimizing Network Slice Resource Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When allocating slices in a network system, existing technologies lead to resource degradation due to fixed resource allocation, resulting in a wasteful use of resources and decreased statistical multiplexing effect.
Innovation Solution
A service allocation determination device and method that assesses service requests against existing slice attributes to decide whether to allocate services to existing or new slices, optimizing resource use by comparing costs and considering isolation requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new slice is created for each service request, then service requirements are guaranteed to be met, but resource wastage increases and statistical multiplexing effect decreases
Solution Approach 1:
The patent merges multiple services into existing slices when resource requirements are satisfied, rather than creating separate slices for each service. The service allocation determination device evaluates whether a new service can be accommodated in an existing slice by comparing service requirements with slice attributes, and combines them if compatible, thereby reducing the total number of slices and improving resource utilization.
Solution Approach 2:
The patent introduces dynamic service allocation where services can be moved between slices based on changing conditions. The service migration determination device evaluates whether migrating a service from one slice to another would improve overall resource utilization, and executes migrations dynamically, transforming the static slice allocation into a dynamic system that adapts to changing service requirements and resource availability.
2Reliability
If fixed resources are allocated to each slice, then service requirements are ensured, but overall resource utilization degrades due to division loss
Solution Approach 1:
The patent applies partial allocation of resources to slices based on actual service requirements rather than allocating full fixed resources. The service allocation determination device calculates the minimum resources needed for each service and allocates only that amount within existing slices, avoiding the division loss that occurs when fixed resources are allocated to each slice regardless of actual needs.
Solution Approach 2:
The patent makes slices universal by allowing them to host multiple different services simultaneously. Instead of dedicating slices to single services, the system evaluates whether existing slices can accommodate additional services with different requirements, enabling slices to perform multiple functions and serve multiple purposes, thereby improving overall resource utilization.
3Reliability
If slices are isolated from each other, then service isolation requirements are met, but resource sharing and multiplexing are reduced
Solution Approach 1:
The patent segments services into different slices based on their isolation requirements. Services that require strict isolation are placed in dedicated slices, while services with lower isolation requirements are placed in shared slices where resource multiplexing is beneficial. This segmented approach maintains necessary isolation while enabling resource sharing where appropriate.
Solution Approach 2:
The patent applies different allocation strategies to different slices based on local requirements. Some slices maintain strict isolation with dedicated resources for services requiring high reliability, while other slices enable resource sharing and dynamic allocation for services with more flexible requirements. This local differentiation allows the system to satisfy isolation requirements where needed while maximizing resource sharing where possible.

AI summary
A service allocation determination device and service allocation determination method that can allocate a service to a slice without wasteful use of resources. In a BSS/OSS, a service request receiving unit receives service requirements and information indicating functions for implementing a service. An allocation determination unit, using the service requirements and slice information, determines whether to allocate the service to an existing slice or to a new slice. An allocation request unit makes a request to allocate the service to the slice determined by the allocation determination unit. In this case, because the BSS/OSS 10 determines whether to allocate the service to an existing slice or to a new slice based on the service requirements and the attribute of the existing slice, the service can be allocated to a slice without wasteful use of resources.
