Called Party Indication Information Delivery via Network Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ring back tone services can only provide preset indications and transmit information through the call media channel, limiting user customization and flexibility, especially for multi-path terminals that support non-call media channels.
Innovation Solution
A method and system that allow the called party to set and provide indication information to the calling party through the network side, enabling the called party to preset and send audio, video, or text information before answering the call, and the network side to obtain and send this information to the calling party, supporting different media formats and user-specific settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ring back tone service uses preset indications stored in operator's server, then service implementation is simplified, but user customization capability is limited
Solution Approach 1:
The called party presets indication information in advance (before the call occurs), and the network side obtains and sends this preset information to the calling party during the call setup phase. This allows user customization while maintaining simplified service implementation through pre-configured settings.
Solution Approach 2:
The network side acts as an intermediary that obtains preset indication information from the called party and delivers it to the calling party. This mediator enables customization capability while keeping the service implementation simplified by centralizing the information exchange process.
2Ease of manufacture
If indication information is transmitted through call media channel, then service implementation is straightforward, but flexibility for multi-path terminals is reduced
Solution Approach 1:
The solution enables indication information to be transmitted through multiple channels (call media channel and non-call media channel), making the service universally compatible with different terminal types including multi-path terminals that support SMS, GPRS, Wi-Fi, or broadband networks.
Solution Approach 2:
The system dynamically selects the appropriate transmission channel based on terminal capabilities. For terminals supporting non-call media channels, the indication information is sent through those channels, while traditional terminals receive information through the call media channel, providing adaptive flexibility.
3Extent of automation
If called party office triggers ring back tone service in PSTN/GSM networks, then service control is centralized, but user-specific customization is limited
Solution Approach 1:
The called party independently presets their own indication information without requiring manual configuration by the called party office. The user-specific customization is achieved through self-service presetting, while the called party office maintains centralized automated control by automatically obtaining and delivering the preset information when calls arrive.

AI summary
The present invention discloses a method for a called party to provide indication information for a calling party. The method includes the steps of: presetting the indication information to be provided to the calling party at the called party; before the called party answers the call in the connection procedure between the calling party and the called party, the network side obtaining the preset indication information from the called party and sending the indication information to the calling party. Accordingly, the present invention discloses a system for a called party to provide the indication information to a calling party. The present invention makes it possible that the called party flexibly selects the indication information to be provided to the calling party and the problem that only the indication information in the indication information database can be provided is avoided.
