Network Control Device Slice Allocation Accuracy

Solution Overview

Problem

Existing network control devices cannot accurately determine whether a new slice can meet the performance requirements of a communication service due to the inability to accurately assess the actual usage of communication resources, leading to inefficient allocation of resources.

Innovation Solution

A network control device that obtains and holds resource information including the maximum usage rate of communication resources for previously generated slices, allowing it to determine if a new slice can be generated based on this information and allocate resources accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If communication resources are allocated based on assumed usage rates, then resource allocation can be performed quickly, but the accuracy of determining whether service performance requirements are met deteriorates

Engineering Contradiction:

Improveaccuracy of determining service performanceVSAvoidcomplexity of resource monitoring

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The network control device performs preliminary actions by obtaining and storing resource usage information from network devices before making allocation decisions. This includes collecting actual usage data from previously allocated slices and preparing it in advance, so that when a new slice allocation request comes, the device can accurately determine service performance requirements without complex real-time calculations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring actual communication resource usage in allocated slices and using this information to improve future allocation decisions. The network control device obtains resource usage information from network devices and uses this feedback to accurately determine whether service performance requirements are met, rather than relying on assumptions.

Inventive Principle:

Principle #23Feedback

2Productivity

If communication resources are allocated without accurate usage information, then allocation speed is maintained, but resource allocation efficiency deteriorates due to over or under allocation

AI summary

A network control device for generating a slice by dividing a network and allocating communication resources to the slice, the slice being a virtual network, the network control device including: a processor; and a memory to store a program which, when executed by the processor, performs processes of: obtaining and holding resource information from a network device included in the network, the resource information including information on a maximum usage rate of communication resources allocated to a previously generated slice in at least one predetermined period; and determining, upon receiving a request for generating a new slice, whether or not the requested slice can be generated on the basis of the resource information held, wherein the resource information includes information on a maximum usage rate of communication resources, which are allocated to the previously generated slice, depending on a request delay concerning the slice in the predetermined period.
