Network Slice Segmentation for Service Startup Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication techniques using network slices face inefficiencies due to the time required to provision network slices before starting communication services.
Innovation Solution
A communication apparatus that requests allocation of a first network slice for processing required for communication services and a second network slice for the services, with the result of processing in the first slice being supplied for communication in the second slice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slices are provisioned before starting communication services, then service quality and resource assurance are improved, but service startup time increases
Solution Approach 1:
The patent segments the network slice provisioning process into two independent parts: (1) a first network slice for performing predetermined processing (e.g., time synchronization), and (2) a second network slice for actual communication services. This segmentation allows the processing slice to be established independently and in parallel with the service slice, eliminating sequential dependencies and reducing overall startup time while maintaining service quality.
Solution Approach 2:
The patent applies preliminary action by establishing the first network slice and performing required processing (such as time synchronization) before the service actually starts. This preprocessing in the first slice prepares necessary conditions (synchronized time, established connections) so that when the second slice is activated for communication, all prerequisites are already met, enabling immediate service startup without delays.
2Reliability
If network slices are provisioned before starting communication services, then resource assurance for each service is improved, but communication efficiency decreases
Solution Approach 1:
By dividing network slice provisioning into separate processing and service slices, the patent enables resource assurance for both functions simultaneously. The first slice secures resources for preprocessing tasks, while the second slice secures resources for communication services. This parallel resource allocation eliminates the trade-off between resource assurance and efficiency, as both can be guaranteed without sequential delays.
Solution Approach 2:
The patent maintains continuous useful action by ensuring that while the first slice performs predetermined processing, the second slice is simultaneously prepared for communication services. This continuous parallel execution of both processing and service preparation eliminates idle time and maintains high productivity throughout the service establishment process, while resource assurance is maintained for both slices.

AI summary
A communication apparatus requests, to a network, allocation of a first network slice for executing predetermined processing required when executing a communication service executed by the communication apparatus and allocation of a second network slice for the communication service, supplies a result of the predetermined processing executed in the first network slice for communication in the second network slice, and performs communication by using the result of the predetermined processing in the second network slice.
