Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Terminal devices that do not support Rich Communication Suite (RCS) messages are unable to present content in its original rich media form, limiting user experience.

Innovation Solution

An RCS message sending server converts RCS messages into web page address information, allowing terminal devices to retrieve content from an RCS message content server using authentication information, ensuring secure access and presentation in rich media form without additional login authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If RCS message content is sent to terminal devices that do not support RCS, then the content can be delivered, but the terminal device cannot present the content in its original rich media form

Engineering Contradiction:

Improverich media content deliveryVSAvoidterminal device compatibility

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a content delivery server as an intermediary between the RCS message application server and non-RCS terminal devices. The server receives RCS messages, extracts rich media content, and delivers it to terminal devices through web page address information. This intermediary enables content delivery to incompatible devices without losing the rich media information.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the RCS message into different components: the message structure is separated from the rich media content. The content is extracted and stored separately on the content delivery server, allowing terminal devices to access only the necessary content through web pages, rather than requiring full RCS message support.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If RCS message content is made accessible to all terminal devices, then user experience is improved, but security risks increase due to potential content leakage

Engineering Contradiction:

Improvecontent accessibilityVSAvoidcontent security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements local quality control by providing different levels of access to different terminal devices. Authentication information is generated specifically for each terminal device based on its capabilities and authorization level. This allows broad accessibility while maintaining security through device-specific access controls.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system implements feedback mechanisms where terminal devices send authentication requests to the content delivery server, which verifies authorization and provides appropriate access. This feedback loop ensures that only authorized devices can access content, maintaining security while enabling widespread accessibility.

Inventive Principle:

Principle #23Feedback

3Reliability

If terminal devices access RCS message content through traditional login authentication, then security is maintained, but operation complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoiduser operation steps

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication actions by generating authentication information in advance when the RCS message is received. This authentication information is embedded in the web page address information, so terminal devices can access content without performing additional login steps during content retrieval. The security check is done beforehand, simplifying the user experience.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If RCS message technology is widely deployed, then rich media communication capability is improved, but device complexity increases due to support requirements

Engineering Contradiction:

ImproveRCS message supportVSAvoidterminal device requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The content delivery server provides universal access to RCS message content for all terminal devices regardless of their native RCS support. By using web page address information and standard web protocols, the system makes RCS content accessible to simple terminal devices without requiring them to implement complex RCS message handling capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method includes that a rich communication suite (RCS) message sending server receives a first message sent by an RCS message application server, where the first message includes an RCS message and user identification information of a terminal device; and when determining that the terminal device does not support an RCS-type message, the RCS message sending server sends web page address information to the terminal device, where the web page address information is used for obtaining content of the RCS message from an RCS message content server.
