Call Preview System Using Media Messages for Caller Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular telephone systems lack sufficient preview information for screening calls, relying solely on phone numbers which do not provide adequate identity information for unknown callers, necessitating frequent updates to contact directories.
Innovation Solution
A call preview system that sends text or media messages containing preview information about the caller, such as name, address, or media files, allowing callers to manage their own data and control what information is sent, enabling display of preview information even for unfamiliar callers not in personal contact directories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system relies solely on phone numbers for caller identification, then the device complexity is low, but the information completeness is insufficient
Solution Approach 1:
The system performs preliminary actions by sending preview messages containing caller information (name, address, media files) before the actual phone call occurs. This allows the receiving device to display comprehensive caller details in advance, eliminating the need for constant contact directory updates and providing complete caller identity information without increasing device complexity.
2Loss of information
If the system stores comprehensive contact information locally, then the information completeness is improved, but the ease of operation deteriorates due to frequent updates required
Solution Approach 1:
The system implements self-service by allowing callers to automatically manage and send their own preview information (name, address, media files) through the network. The receiving device automatically receives and displays this information without requiring manual contact directory updates by users, thus maintaining complete caller identity information while significantly improving ease of operation.
3Loss of information
If the system sends detailed preview messages for all callers, then the information completeness is improved, but the use of energy increases
Solution Approach 1:
The system applies local quality by allowing users to selectively enable or disable preview information transmission for different callers or time periods. Users can configure which types of information (text, media files) are sent based on specific callers, thereby providing complete information when needed while reducing energy consumption during periods or for callers where detailed information is not required.

AI summary
A caller may initiate a phone call to a device. A call preview system may send a preview message in conjunction with the phone call. The preview message may contain preview information that identifies the caller. The call preview system may use a text or media messaging service to send the preview message. Callers can manage their own preview information relieving each user from continuously updating contact information in personal contact directories. The call preview system may use different schemes for initiating phone calls. In one example, the call preview system may initiate or forward phone calls in conjunction with sending the preview message. In another example, the call preview system may delay calling a phone number or delay forwarding the phone call until a message is received acknowledging the preview message or accepting the phone call.
