Ring Back Tone Server Personalization via Intermediary Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks provide uniform and tedious ring back tones, failing to satisfy individual subscriber preferences and limiting service quality, as they cannot differentiate between subscribers based on ring back tones and do not allow customization.
Innovation Solution
A method and system that include a ring back tone device and a Service Control Point (SCP) or Signaling Processing System (SPS) to store and play subscriber-customized ring back tones, allowing registered subscribers to choose personalized ring back tones by connecting the call through a ring back tone device when the called terminal is idle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform traditional ring back tones are used in conventional communication networks, then network simplicity is maintained, but subscriber individualization requirements cannot be satisfied
Solution Approach 1:
The patent introduces a Ring Back Tone Server (RBTS) as an intermediary component between the switching network and subscribers. This server stores multiple ring back tone files and provides personalized ring back tones to calling subscribers based on the called subscriber's preferences, enabling customization without requiring complex modifications to the core switching network architecture.
Solution Approach 2:
The patent segments the ring back tone service function from the core switching network by creating a separate Ring Back Tone Server. This segmentation allows the customization logic and tone storage to be isolated in a dedicated component, maintaining the simplicity of the existing switching infrastructure while adding adaptability through the specialized server.
2Reliability
If subscriber-customized ring back tones are implemented, then service quality and user experience are enhanced, but additional network components and control systems are required
Solution Approach 1:
The Ring Back Tone Server is designed to handle multiple functions: storing various ring back tone files, determining which tone to play based on subscriber preferences, and interfacing with the switching network. This multi-functionality consolidates several operations into a single component, reducing overall system complexity despite adding customization capabilities.
Solution Approach 2:
The system enables subscribers to self-select and customize their preferred ring back tones through interaction with the Ring Back Tone Server. This self-service approach allows users to control their own service preferences without requiring manual network configuration, improving service quality while minimizing network operator workload.
3Adaptability or versatility
If traditional switching devices play all ring back tones, then device functionality is sufficient, but individual subscriber preferences cannot be accommodated
Solution Approach 1:
The Ring Back Tone Server acts as a mediator between the traditional switching devices and subscriber preferences. The switching devices continue to operate traditionally by routing calls, while the RBTS handles the complexity of selecting and playing personalized ring back tones based on subscriber profiles stored in its database.
Solution Approach 2:
The system creates virtual copies of ring back tone services by storing multiple tone files in the Ring Back Tone Server and selectively playing appropriate tones. Instead of requiring each switching device to store and manage multiple tones, the system uses a centralized copy library that serves all subscribers, enabling personalization without distributing complexity across multiple devices.

AI summary
Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
