Mobile Terminal Missed Call Display Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals only display the number of missed calls without providing information on who missed the call, how many times, or the type of event, leading to user confusion and a lack of convenience in checking event information received in absence.
Innovation Solution
A method and apparatus for a mobile terminal that displays a message for a missed call on the idle screen or call list screen, shows call history on incoming or outgoing call screens when a call is received or made, and changes the message when the call is connected, removing it from the idle screen and displaying it on the call list screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a message for missed calls is displayed on the idle screen showing only the number of events, then the user can check the count of received events, but various detailed information such as caller identity, call frequency, and event type cannot be provided
Solution Approach 1:
The display system is segmented into multiple screens with different functions: the idle screen displays only the count of missed calls to maintain simplicity, while the call list screen displays detailed information including caller identity, call frequency, and event type. This segmentation allows the system to provide comprehensive information without overwhelming the idle screen interface.
Solution Approach 2:
The patent transitions from a two-dimensional idle screen display to a multi-dimensional information presentation by utilizing the call list screen as an additional dimension. When the user navigates to the call list screen, detailed missed call information is displayed in a structured format with multiple dimensions of data (caller name, number of calls, timestamps), effectively adding informational depth without complicating the idle screen.
2Ease of operation
If a message for a missed call disappears only when the user checks phone history, then the message remains visible as a reminder, but the user may be confused as the message displays or disappears regardless of whether the user connects with the missed call number
Solution Approach 1:
The system implements feedback mechanisms that actively monitor user actions related to missed calls. When the user views the call list or initiates a call to the missed number, the system detects these actions and automatically updates the idle screen message accordingly - either removing it or updating its content. This feedback loop ensures the message state accurately reflects the user's interaction status, eliminating confusion about when the message should disappear.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the idle screen message to be dynamically responsive to specific user actions. Before the user even checks the phone history, the system has already set up the logic to automatically remove or update the message when certain conditions are met (viewing call list, making a call), so the message behavior is predetermined and consistent, reducing user confusion.
3Adaptability or versatility
If various applications and functions are added to the mobile terminal, then the terminal provides more capabilities, but the basic function of displaying and managing missed call information becomes less effective
Solution Approach 1:
The patent extracts the missed call management functionality from the complex ecosystem of multiple applications and isolates it into a dedicated, streamlined interface. The idle screen provides a simple, application-agnostic display of missed call counts, while the call list screen handles detailed information. This extraction ensures that missed call management remains intuitive and unaffected by the proliferation of other applications and functions in the terminal.

AI summary
A displaying method and apparatus in a mobile terminal are provided. The displaying method in a mobile terminal includes displaying a message for a missed call for a first number on an idle screen or a call list screen when the missed call is generated from the first number, displaying a call history for the first number on an incoming call screen or an outgoing call screen when a call is received from the first number or the call is transmitted to the first number, and changing the message for the missed call for the first number when a call is connected to the first number and displaying the changed message.
