Dial Pad Information Transmission During Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in transmitting information, such as account numbers or letters, during phone calls on mobile terminals, as existing technologies do not provide a convenient method for doing so.
Innovation Solution
An information transmission method and apparatus that executes an application program to display an application interface alongside the dial pad during a call, allowing information to be transmitted through the dial pad based on the content of the application interface, using a floating button or notification bar input, and enabling overlapping display of the dial pad and application interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input information during a call, then information can be transmitted to the other party, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent stores information (account numbers, letters, etc.) in advance within application programs before the call occurs. During the call, users can directly transmit this pre-stored information through the dial pad without manual input, thus resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The patent creates a copy of the stored information and transmits it through the dial pad during the call. Instead of requiring users to re-input information manually, the system copies the pre-stored data and sends it automatically, improving convenience and reducing time consumption.
2Ease of operation
If the dial pad and application interface are displayed separately, then each can be fully visible, but the user cannot easily access both during a call
Solution Approach 1:
The patent transitions from a single-screen sequential display to a multi-screen simultaneous display. The dial pad is displayed on one screen while the application interface is displayed on another screen, allowing users to access both interfaces concurrently during the call without compromising display area or operational accessibility.
3Adaptability or versatility
If only the dial pad is displayed during a call, then the call function is maintained, but information transmission from application programs is not convenient
Solution Approach 1:
The patent makes the dial pad multi-functional by enabling it to serve both its traditional calling function and an additional information transmission function. Through this universal design, the dial pad can transmit information from various application programs during the call without requiring separate interfaces or increasing system complexity.

AI summary
An information transmission method, which is a method in which an information transmission apparatus transmits information through a dial pad during a call in a terminal, includes: executing an application program storing all or part of the information and displaying an application interface including the all or part of the information; executing the dial pad in a state where the application interface is displayed, and simultaneously displaying the dial pad and the application interface; and transmitting the information to another party through the dial pad, based on content of the application interface.
