Terminal Group QoS Initiation via D2D and Network Triggers

Solution Overview

Problem

Conventional techniques face difficulties in initiating Network as a Service (NaaS) configurations for groups of terminals in Device-to-Device (D2D) communication scenarios, particularly in providing Quality of Service (QoS) guarantees across multiple terminals without manual intervention.

Innovation Solution

A terminal is equipped with a reception unit to obtain information for starting a service that performs priority control related to communications within a group, and a control unit to initiate the service via direct communication between terminals or through the network, enabling QoS provisioning across the group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional techniques are used for D2D communication, then basic communication functionality is achieved, but a terminal cannot initiate NaaS configuration for other terminals or terminal groups

Engineering Contradiction:

ImproveTerminal initiative to trigger NaaSVSAvoidNaaS configuration complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The terminal is enabled to autonomously initiate NaaS configuration requests for itself and for other terminals/groups through direct communication or network triggers, eliminating the need for manual configuration and allowing terminals to self-manage their service subscriptions

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The network acts as an intermediary that receives NaaS configuration requests from terminals and distributes appropriate configurations to target terminals or groups, enabling indirect configuration initiation while maintaining system-wide coordination

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If manual configuration of NaaS for each terminal is performed, then QoS can be provided individually, but the process becomes time-consuming and complex for group communications

Engineering Contradiction:

ImproveQoS provisionVSAvoidConfiguration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Multiple terminal configurations are merged into a single group-based NaaS configuration that can be initiated by one terminal and applied to multiple terminals simultaneously, reducing configuration time while maintaining individual QoS requirements through group membership

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If D2D communication is implemented without group-based NaaS, then simple peer-to-peer communication is achieved, but QoS cannot be provided across terminal groups

Engineering Contradiction:

ImproveQoS group provisioningVSAvoidService configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The NaaS configuration mechanism is designed to universally apply to multiple scenarios including individual terminal configuration, group-based configuration, and dynamic service initiation, allowing a single system to handle diverse QoS requirements across different communication patterns

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A terminal includes: a reception unit configured to obtain information for starting a service that performs priority control related to communications, the service being applied to a group to which one or more terminals belong; and a control unit configured to start the service for the terminals that belong to the group, by using the information and by a trigger via direct communication between terminals or via a network.
