Customized Alerting Tone Video Playback During VoLTE Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current VoLTE systems, customized alerting tones stop playing after the called user picks up the phone, limiting user experience and service development.
Innovation Solution
A call processing method and device that continues playing customized alerting tone videos to the calling terminal during an audio call by performing call media and customized alerting tone video resource negotiations after the called terminal goes off-hook, ensuring seamless integration with 4G and future network architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If customized alerting tone stops playing after called user picks up phone, then call processing is simple, but user experience is limited and service development is constrained
Solution Approach 1:
The patent applies dynamics by making the alerting tone playback state changeable based on call status. The system dynamically transitions from ringing phase playback to call phase playback, allowing the alerting tone to continue playing during the call according to user subscription preferences. This dynamic state adjustment resolves the contradiction by enabling enhanced user experience without requiring fundamentally complex processing architecture.
Solution Approach 2:
The patent changes the playback parameter from binary (stop/continue) to conditional (continue based on subscription and call status). By introducing parameters such as user subscription status, call phase detection, and playback configuration, the system achieves flexible control of alerting tone playback during calls, improving user experience while maintaining manageable processing complexity through parameter-based decision logic.
2Adaptability or versatility
If customized alerting tone continues playing during audio call, then user experience is enriched and network capabilities are improved, but additional resource negotiation and processing are required
Solution Approach 1:
The patent applies universality by making the customized alerting tone service multi-functional. The same alerting tone infrastructure serves both the traditional ringing phase function and the new call phase function. By designing the system to handle both phases through a unified service architecture, the patent achieves enhanced service versatility without proportionally increasing system complexity, as the additional functionality builds upon existing components.
Solution Approach 2:
The patent applies preliminary action by performing resource negotiation and configuration setup during the ringing phase before the call is answered. The customized alerting tone video stream is prepared and negotiated in advance, so when the call is answered, the system can quickly transition to playing the alerting tone during the call without requiring complex real-time negotiation. This preliminary preparation reduces the complexity burden during the critical call phase.
3Productivity
If customized alerting tone video stream is played during audio call, then network capabilities are utilized effectively, but media resource negotiation is required
Solution Approach 1:
The patent applies preliminary action by completing media resource negotiation and video stream preparation during the ringing phase before the call is answered. The customized alerting tone video stream is negotiated and configured in advance, allowing the system to simply execute playback during the call without complex real-time negotiation. This preliminary action effectively utilizes network capabilities while minimizing the complexity burden during the call phase.
Solution Approach 2:
The patent applies continuity of useful action by maintaining the customized alerting tone playback as a continuous service during both ringing and call phases. The video stream playback continues without interruption or re-negotiation once established, allowing the system to effectively utilize network capabilities for enhanced user experience while avoiding repeated complex media resource negotiation during the call.

AI summary
The present invention provides a call processing method and a device. The call processing method includes: receiving, by a customized alerting tone server, a call request sent by a calling terminal, and forwarding the call request to a called terminal; receiving a called terminal ringing message, and playing a customized alerting tone audio stream and a customized alerting tone video stream to the calling terminal; receiving a called terminal off-hook message, and performing call media resource negotiation and customized alerting tone video resource negotiation with the calling terminal; and stopping playing the customized alerting tone audio stream to the calling terminal, and playing the customized alerting tone video stream to the calling terminal. The customized alerting tone continuous playing solution of the present invention enriches user experience and improves network usage.
