Network Slice Configuration for TCP Communication Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for managing communication quality in network slices using TCP/IP cannot effectively handle situations where different qualities of communication (such as bandwidth, delay, and reliability) are required for each instance of communication, leading to inadequate control.
Innovation Solution
A communication apparatus and method that determine the configuration of network slices based on the state of communication and required quality, requesting adjustments from a network orchestrator to allocate appropriate resources for each protocol used, ensuring that data transmission occurs over the correct network slice according to the specified quality requirements.

Engineering Contradiction Analysis
1Productivity
If network slice management uses statistical information of TCP/IP communication, then bandwidth control is achieved, but appropriate quality control for each communication instance cannot be performed
Solution Approach 1:
The patent segments the network slice management by creating separate QoS control mechanisms for each communication instance. The QoS control unit divides the overall network management into instance-specific control units, allowing independent quality parameters (bandwidth, delay, reliability) to be set and managed for each TCP/IP communication instance rather than using unified statistical information.
Solution Approach 2:
The patent implements dynamic QoS control where quality parameters can be changed in real-time for each communication instance. The QoS control unit dynamically adjusts bandwidth, delay, and reliability settings based on individual instance requirements, enabling adaptive quality control that responds to changing communication needs rather than relying on static statistical averages.
2Ease of operation
If unified TCP/IP communication management is used, then simple control is maintained, but different quality requirements for different communication instances cannot be handled
Solution Approach 1:
The patent introduces a QoS control unit as an intermediary layer between the network slice management and individual communication instances. This intermediary maintains simple overall control while implementing instance-specific quality management by acting as a mediator that translates general network resources into instance-specific quality guarantees without requiring complex direct control of each instance.
Solution Approach 2:
The QoS control unit is designed with multi-functionality, handling multiple quality parameters (bandwidth, delay, reliability) for multiple communication instances simultaneously. This universal control mechanism maintains operational simplicity while providing comprehensive quality control across different instances through a single integrated unit rather than separate controls for each instance.
3Device complexity
If network slices are allocated based on general communication statistics, then resource allocation is simplified, but appropriate resource allocation for each protocol instance cannot be achieved
Solution Approach 1:
The patent applies local quality by allocating network slice resources according to the specific requirements of each protocol instance rather than using uniform allocation based on general statistics. The QoS control unit determines appropriate quality parameters (bandwidth, delay, reliability) for each individual TCP/IP communication instance, ensuring that resource allocation matches the local needs of each protocol instance.

AI summary
A communication apparatus that performs communication that uses Transmission Control Protocol (TCP) via one or more network slices determines a respective configuration of the one or more network slices based on a respective state of the communication that uses TCP in the one or more network slices and a respective required quality in the one or more network slices, and makes a request to an apparatus that manages the one or more network slices so as to perform the determined configuration.
