Solution Overview

Problem

Current 5G network slicing technologies face challenges in efficiently allocating network resources based on diverse application demands and user roles, leading to inconsistent network experiences, particularly in online meetings where bandwidth, prioritization, and resource management are critical.

Innovation Solution

The implementation of application-specific network slices, where application providers generate generic service templates that include role-based network requirements, allowing mobile network operators to dynamically recommend and allocate suitable network slices for each user based on their role and meeting characteristics, ensuring optimized resource allocation and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If generic network slicing is used without application-specific customization, then network infrastructure complexity is reduced, but network service quality and user experience deteriorate due to inconsistent resource allocation

Engineering Contradiction:

Improvenetwork infrastructure complexityVSAvoidnetwork service quality

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent segments network slicing into two levels: generic network slices for basic infrastructure and application-specific network slices for customized service delivery. This segmentation allows the system to maintain simple generic slices while creating specialized slices for specific applications like online meetings, thereby resolving the contradiction between infrastructure simplicity and service quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic network slice selection based on application type and user role. The system dynamically determines whether to use generic or application-specific slices based on real-time requirements, enabling flexible resource allocation that maintains service quality without permanently increasing infrastructure complexity.

Inventive Principle:

Principle #15Dynamics

2Reliability

If application-specific network slices are implemented, then network service quality is improved, but device complexity increases due to additional slice management requirements

Engineering Contradiction:

Improvenetwork service qualityVSAvoidslice management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism (the network system itself) that automatically manages application-specific slice selection. Rather than requiring end devices to complexly manage multiple slices, the system acts as an intermediary that transparently handles slice determination and allocation based on application and role information, improving service quality without burdening devices with management complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If network resources are allocated without role-based differentiation, then resource management simplicity is maintained, but user experience deteriorates due to inconsistent service delivery

Engineering Contradiction:

Improveresource management simplicityVSAvoidservice consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by differentiating network resource allocation based on specific user roles within applications. Instead of uniform resource management, the system tailors network slice characteristics (bandwidth, latency, priority) to specific roles such as presenters, attendees, or organizers in online meetings, ensuring service consistency for each role while maintaining overall system simplicity through automated role-based determination.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If dynamic network slice selection based on application and role is implemented, then service customization is improved, but information processing requirements increase

Engineering Contradiction:

Improveservice customizationVSAvoidinformation processing energy

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by pre-defining role-based network requirements and application-specific slice templates. Instead of performing complex real-time analysis, the system uses pre-configured information about typical network needs for different roles and applications, significantly reducing information processing energy while maintaining high service customization capability.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed are systems, apparatuses, methods, and computer-readable media for participating in a meeting through an application provider using application-specific network slices. A method includes transmitting a request to a mobile network operator (MNO) for setup of a data connection with a device for a meeting provided by an application provider; receiving allowed network slices for the data connection that are generated by the MNO for the meeting; identifying a network slice from the allowed network slices for the meeting based on one or more characteristics specific to the meeting; and establishing the data connection with the mobile network operator based on the network slice.
