Solution Overview

Problem

Existing personalized Ring Back Tone services are unidirectional, failing to allow called users to determine the identity of the calling party from the ring tone, which frustrates user experience.

Innovation Solution

A method and system that enables interactive Ring Back Tone services by obtaining subscription information during a call, issuing identifiers to switching devices, and connecting sessions between terminals and an interactive Ring Back Tone service platform to play customized tones to both calling and called users, allowing called users to hear a Ring Back Tone set by the callee.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a unidirectional Ring Back Tone service is implemented where the calling party hears a personalized ring tone customized by the callee, then the callee can provide a personalized ring tone experience, but the called party cannot determine the identity of the calling party from the ring tone

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidcalling party identity information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies inversion by enabling the called party to hear a Ring Back Tone customized by themselves (reversing the traditional direction), allowing them to identify the calling party through their own customized tone rather than the caller hearing the callee's tone

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a service platform as an intermediary that manages dual subscription identifiers (first and second subscription identifiers) and coordinates the interaction between calling and called parties, enabling the called party to hear their own customized Ring Back Tone while the caller hears the traditional tone

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a dual subscription identifier system is implemented to enable interactive Ring Back Tone, then both calling and called parties can hear personalized tones, but the system complexity increases with multiple switching devices and subscription identifiers

Engineering Contradiction:
Improveinteractive personalizationVSAvoidswitching device coordination
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the Ring Back Tone service into two independent subscription identifiers: a first subscription identifier for the calling party and a second subscription identifier for the called party. This segmentation allows each identifier to be managed independently by different switching devices, reducing the coordination complexity while enabling interactive personalization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The service platform acts as an intermediary that manages the dual subscription identifier system, coordinating between the first switching device (which obtains the second subscription identifier) and the second switching device (which issues the first subscription identifier), thereby simplifying the overall system architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method and system for realizing interactive ring back tone are provided, the method includes getting the contract information of interactive ring back tone services signed by the user during the process of continuous calling (S101); the first contract mark that identifies the user who signs the interactive ring back tone services is sent to a called terminal, the said first contract mark is used for indicating that the called terminal is waiting for playing the interactive ring back tone, when the called terminal is free (S102); the interactive ring back tone is played for the called user depending on the interactive ring back tone services signed by the user (S103).
