Solution Overview

Problem

The VoLTE system lacks the architecture to integrate with internet services, limiting the ability to enhance user experience during calls or conferences with features like background music or language translation.

Innovation Solution

A framework is introduced to integrate call/conference services with external internet services by adding an internet application server as a session participant, allowing control of multimedia resources based on media models for uploading, downloading, or mixing media between the IMS and internet services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the VoLTE system maintains its existing closed architecture, then system stability and reliability are preserved, but the ability to integrate with external internet services is limited

Engineering Contradiction:
Improveintegration capability with internet servicesVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the system architecture by introducing a dedicated Internet Service Gateway (ISG) component that separates internet service integration functions from the core VoLTE system. This allows the VoLTE system to maintain its stable closed architecture while the ISG handles all internet service integration, enabling adaptability without compromising system stability or adding complexity to the core system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The Internet Service Gateway (ISG) acts as an intermediary between the VoLTE system and external internet services. It mediates all interactions by receiving service requests from the VoLTE system, translating them into appropriate internet service protocols, and returning results. This intermediary approach enables integration capability while keeping the core VoLTE system unchanged and simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If internet services are integrated into VoLTE calls, then user experience is enhanced with features like background music and translation, but the device complexity increases

Engineering Contradiction:
Improveuser experience qualityVSAvoidsystem architecture complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts internet service integration functionality from the core VoLTE system and places it in a separate Internet Service Gateway (ISG). This extraction allows enhanced user experience through internet services like background music and translation while preventing the core VoLTE system from becoming complex. The ISG handles all service integration logic, keeping the main system simple.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The Internet Service Gateway (ISG) is designed as a universal component that can handle multiple types of internet services (background music, language translation, information services) through a single integrated interface. This multi-functionality approach enhances user experience with diverse features while avoiding the need to add separate complex integration mechanisms for each service type in the core VoLTE system.

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

3Adaptability or versatility

If the VoLTE system integrates multiple internet services, then service functionality is enhanced, but the difficulty of system management and control increases

Engineering Contradiction:
Improveservice integration capabilityVSAvoidservice management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Internet Service Gateway (ISG) serves as a centralized intermediary that manages all internet service integrations. It receives uniform service requests from the VoLTE system, translates them into service-specific protocols, and manages the complexity of multiple service integrations in one location. This approach enhances service functionality while centralizing management control and preventing distributed complexity throughout the system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates an equipotential interface between the VoLTE system and various internet services through the ISG. The ISG presents a unified, standardized interface to the VoLTE system regardless of the underlying service complexity. This allows the VoLTE system to access multiple enhanced services without experiencing increased management difficulty, as all services are accessed through the same simplified interface.

Inventive Principle:
Principle #12Equipotentiality

AI summary

Methods and apparatuses are disclosed for enhancement to an internet protocol (IP) multimedia subsystem (IMS). According to an embodiment, an application server (AS) of the IMS receives from a terminal device a first request for initiating a call service and an internet service which are to be integrated with each other. The AS of the IMS sends a second request for initiating the internet service to a gateway server that acts as a gateway to an internet AS capable of providing the internet service. In response to a reply from the gateway server, the AS of the IMS handles the first request based on the reply.
