Communication Slice Allocation Using Priority Policies Without Statistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for allocating communication resources to logical networks fail to reserve new slices when statistical information is unavailable, leading to insufficient resource availability.
Innovation Solution
A resource allocation device that includes a slice request acquisition unit, a request value selection unit, and a resource allocation unit, which selects request values based on priority levels and allocates resources accordingly, even in the absence of statistical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If statistical information is required to calculate reducible bandwidth, then resource allocation accuracy is improved, but system adaptability deteriorates when statistical information is unavailable
Solution Approach 1:
The system performs preliminary actions by pre-defining request value selection policies and request value ranges before actual resource allocation occurs. The request value selection unit holds policy tables that specify how to select request values based on priority levels, enabling the system to operate without statistical information from historical data.
Solution Approach 2:
The request value selection unit autonomously selects request values based on predefined policies and priority levels without requiring external statistical information. The system serves itself by using internal policy tables to make allocation decisions, eliminating dependency on external statistical data for operation.
2Productivity
If request values are selected based on priority levels, then resource allocation efficiency is improved, but measurement precision deteriorates due to lack of statistical data
Solution Approach 1:
The system changes the parameter basis for resource allocation from statistical data-driven to priority-level-driven. Instead of using historical statistical information to determine allocation, the system uses predefined priority levels and request value ranges to select appropriate request values, achieving efficiency through policy-based decision making.
Solution Approach 2:
The request value selection unit acts as an intermediary between the slice request acquisition unit and the resource allocation unit. It mediates the allocation process by selecting request values based on priority levels and policy tables, translating high-level priorities into specific allocation parameters without requiring statistical information.

AI summary
A resource allocation device includes a slice request acquisition unit that receives a slice request including information indicating a request value range and a priority level for each of plural attributes of a slice; a request value selection unit that holds a request value selection policy table showing how to select a request value for each of the plural attributes from the request value range on the basis of the priority level and selects the request value for each of the plural attributes of the slice on the basis of request value selection policy indicated by the request value selection policy table; and a resource allocation unit that allocates a resource to the slice on the basis of the request value.
