Solution Overview

Problem

In communication terminal devices, relaying communication data between end devices and a group communication server can lead to unnecessary resource consumption, as data is sent twice through intermediate devices, wasting communication resources.

Innovation Solution

Implementing a communication terminal device with a controller that determines whether to relay messages and modifies them accordingly, using protocols like SIP and RTP/RTCP, to ensure data is sent only once and efficiently between devices, bypassing the need for direct connections with base stations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an end device relays communication data from a group communication server to another end device, then communication coverage is extended to devices not directly connected to base stations, but communication resources are consumed unnecessarily as data is sent twice to the relaying end device

Engineering Contradiction:
Improvecommunication coverageVSAvoidcommunication resource consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts the relaying function from the end device itself and implements it in a separate relay device. The controller in the end device determines that another end device should relay communication data, and this relaying is performed by a dedicated relay device rather than the end device itself, thereby eliminating the waste of sending data twice to the relaying end device while maintaining extended communication coverage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a relay device as an intermediary between the group communication server and end devices. This intermediary relay device receives communication data from the server and forwards it to target end devices, preventing the need for data to be sent to relaying end devices and eliminating redundant communication resource consumption while maintaining network coverage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If an end device relays communication data from another end device to a group communication server, then group communication is enabled without direct base station connection, but communication resources are consumed unnecessarily as relayed data is sent back to the relaying end device

Engineering Contradiction:
Improvecommunication connectivityVSAvoidcommunication resource consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts the relay functionality from end devices and assigns it to a dedicated relay device. When communication data needs to be relayed to the group communication server, the relay device performs this function centrally, preventing multiple end devices from unnecessarily receiving and retransmitting data, thus reducing communication resource consumption while maintaining connectivity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The relay device serves as an intermediary that consolidates the relaying function. Instead of multiple end devices acting as relays and consuming resources by receiving and retransmitting data, a single relay device mediates all relayed communication data between end devices and the group communication server, eliminating redundant data transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If all end devices must be connected to the central group communication server, then centralized control is maintained, but end devices without direct base station connection cannot communicate with the group

Engineering Contradiction:
Improvecentralized controlVSAvoidcommunication accessibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces relay devices as intermediaries that enable end devices without direct base station connections to communicate with the central group communication server. The relay devices receive data from the server and forward it to remote end devices, and vice versa, thereby maintaining centralized control through the server while extending accessibility to devices that would otherwise be isolated.

Inventive Principle:
Principle #24Intermediary (Mediator)
