Solution Overview

Problem

Current ring back tone services do not allow for personalized multimedia experiences when the called party is in a non-idle state, such as busy, power-off, or using supplementary services, limiting user customization and enhancing the user experience.

Innovation Solution

A status prompt multimedia playing method and system that involves a telephony application server and a status prompt application server, which negotiate multimedia capabilities to play personalized status prompt multimedia to the calling party when the called party is in a non-idle state, using identifiers like call busy or power-off states to trigger customized multimedia playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional ring back tone service is provided only when called party is idle, then network simplicity is maintained, but service versatility and user customization capability are limited

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

Solution Approach 1:

The patent segments the ring back tone service into multiple independent modules: idle state service, non-idle state service, multimedia capability negotiation module, and status prompt delivery module. This allows the system to add versatile non-idle state services without overwhelming complexity, as each module handles specific functionality independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-negotiating multimedia capabilities between calling and called parties before the actual call connection. The system prepares status prompt multimedia resources in advance and establishes capability agreements, enabling seamless service delivery during non-idle states without real-time complexity.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If personalized status prompt multimedia is enabled for non-idle states, then user experience and service enrichment are improved, but multimedia capability negotiation complexity increases

Engineering Contradiction:
Improveuser experienceVSAvoidnegotiation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a multi-functional multimedia capability negotiation mechanism that handles multiple scenarios (idle, busy, power-off, supplementary services) through a unified SDP-based framework. This single negotiation system serves multiple purposes, improving user experience across different states without proportionally increasing complexity.

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

Solution Approach 2:

The patent introduces an intermediary status prompt application server that mediates between the calling party's terminal and the called party's preferences. This intermediary handles complex multimedia capability negotiation and status prompt selection, simplifying the interaction for end users while managing negotiation complexity centrally.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multimedia capability negotiation is implemented between status prompt application server and calling terminal, then personalized multimedia playback is achieved, but signaling overhead and processing time increase

Engineering Contradiction:
Improvemultimedia playback reliabilityVSAvoidnegotiation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs multimedia capability negotiation as a preliminary action during call setup, before the actual call is connected. By completing capability agreements and resource preparations in advance, the system ensures reliable personalized multimedia playback during non-idle states without adding significant time loss during the critical call moment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuity of useful action by keeping multimedia capability information cached and reusable across multiple call scenarios. Once capabilities are negotiated and agreed upon, this information continues to serve subsequent calls and status prompts without requiring repeated full negotiations, reducing overall processing time while maintaining reliability.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

Embodiments of this application disclose a status prompt multimedia playing method, including: receiving, by a status prompt application server, a first multimedia request that includes a non-idle identifier and that is sent by a TAS, sending a first multimedia response including a status prompt multimedia session description protocol SDP to the TAS, and receiving a first multimedia acknowledgement message that includes a calling-side multimedia SDP and that is sent by the TAS. In this way, the status prompt application server obtains the calling-side multimedia SDP, and implements negotiation and acknowledgement of multimedia capability sets between the status prompt application server and a calling terminal device; and the status prompt application server can play corresponding status prompt multimedia for the calling terminal device based on different non-idle identifiers. This implements playing of personalized status prompt multimedia in a non-idle state scenario.
