Video Call Failure Prompting via Local Terminal Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video telephone service systems lack a simplified method for prompting users about call failures, requiring complex processes involving mobile switching centers, additional network elements, and fixed audio/video media files.
Innovation Solution
A terminal and method that utilize a processing module, storing module, and setting module to set and store failure prompt information and corresponding prompting modes, allowing for voice, text, or video prompts to be sent to users upon call failures, with the ability to generate prompt messages automatically if no user action is taken within a specified time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional voice promptings are used to notify users of call failure in video calls, then the service can maintain simplicity, but the system cannot provide personalized failure reason notifications and user customization
Solution Approach 1:
The terminal performs self-service by locally storing failure prompt information and prompting modes, and automatically generating and sending personalized failure notification messages without requiring complex network element involvement. The terminal configures its own failure notification behavior through the setting module and processing module.
Solution Approach 2:
The system segments the failure notification function into distinct components: failure reason identification (processing module), prompt mode selection (setting module), and message generation (processing module). This segmentation allows each component to operate independently, reducing overall system complexity while enabling personalization.
2Reliability
If additional network elements and fixed audio/video media files are added to provide failure reasons, then failure notification capability is improved, but the process becomes complicated and less flexible
Solution Approach 1:
The invention extracts the failure notification function from the complex network-based system and relocates it to the terminal itself. The terminal directly stores failure prompt information and generates notifications locally, eliminating the need for additional network elements like the failing reason playing net element mentioned in the background.
Solution Approach 2:
The system replaces fixed audio/video media files with dynamic text-based failure prompt information that can be customized according to user needs. The processing module can generate different notification messages based on the failure reason and user settings, providing flexibility rather than fixed content.
3Loss of information
If the system checks failure reasons in the mobile switching center and transmits them to network elements, then failure reason identification is achieved, but the process requires multiple steps and additional devices
Solution Approach 1:
The invention merges the failure reason identification function with the terminal's local storage and processing capabilities. Instead of separating failure reason checking (MSC), transmission (network element), and playback (terminal) into distinct steps and devices, the terminal integrates all these functions locally, reducing system structure complexity while maintaining information completeness.
Data Source
AI summary
A terminal and a method for prompting service failure in the video telephone service are disclosed, and the terminal comprises a processing module, a storing module and a setting module which are connected orderly. Said terminal sets and stores the corresponding relationship between different failure prompt information and prompting modes according to the user's command, and when the terminal receives a video telephone call request and the called user performs the failure prompting operation, the terminal generates a call failure prompt message according to the preset failure prompt information and the prompting mode corresponding to said failure prompt information and sends it to the calling user. After the calling user terminal receives said call failure prompt message, it analyzes and acquires the failure prompt information and the corresponding prompting mode, and displays and/or plays the failure prompt information to the calling user according to the prompting mode.
