Solution Overview

Problem

Existing messaging services from Mobile Network Operators (MNOs) and Internet companies operate independently, limiting cross-service communication, especially for features like message attachments, delivery receipts, and read receipts, with users often restricted to their own ecosystems.

Innovation Solution

A system enabling inter-partner messaging through user identification, routing target resolution, and IMS core routing, using NAPTR and SRV records to facilitate communication between MNOs and internet-based messaging services, allowing for standardized communication protocols like SIP and HTTP for message delivery and file transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If messaging services operate independently within their own ecosystems, then service reliability is maintained, but communication versatility between different platforms is lost

Engineering Contradiction:
Improvecommunication versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an inter-partner messaging service as an intermediary layer between mobile network operators and internet-based messaging services. This mediator translates messages between different protocols and formats, enabling cross-platform communication without requiring changes to the underlying independent messaging systems. The intermediary handles protocol conversion, routing decisions, and format translation, thus maintaining service independence while achieving communication versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The inter-partner messaging service is designed with universal functionality to handle multiple messaging protocols and formats simultaneously. It can process SMS, MMS, instant messaging, and other message types through a unified interface, allowing a single system to perform multiple communication functions across different platforms without requiring separate specialized systems for each message type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If messaging services use proprietary formats, then service reliability is improved, but interoperability between services deteriorates

Engineering Contradiction:
Improveservice reliabilityVSAvoidinteroperability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs parameter changes by transforming message parameters between different formats. The inter-partner messaging service modifies message parameters such as protocol type, encoding format, routing information, and header structure to adapt messages from one service format to another. This allows the system to maintain the reliability of proprietary formats while achieving interoperability through dynamic parameter transformation.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If cross-platform messaging is enabled, then communication versatility is improved, but message format compatibility problems arise

Engineering Contradiction:
Improvecommunication versatilityVSAvoidmessage format compatibility
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The format translation capability acts as a mediator between different message formats. It receives messages in various proprietary formats, validates and standardizes them according to the inter-partner messaging service specifications, and then translates them into the appropriate format for the target platform. This ensures format compatibility while maintaining the ability to communicate across diverse platforms.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If independent messaging ecosystems are maintained, then service stability is improved, but user communication capability across platforms is limited

Engineering Contradiction:
Improveservice stabilityVSAvoiduser communication capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The inter-partner messaging service enables self-service communication across platforms by automatically handling protocol conversion, routing, and format translation without requiring user intervention. Users can communicate across different messaging ecosystems using their familiar interfaces and protocols, while the system autonomously manages the complexity of cross-platform compatibility, thus maintaining service stability while improving ease of operation.

Inventive Principle:
Principle #25Self-service
