Apparatus and method for processing call services in mobile terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals lack the ability to propose user actions in advance during ongoing calls, disrupting the conversation as users often need to perform additional tasks like checking schedules or messages, which can be inconvenient and distracting.
Innovation Solution
A call service processing apparatus and method that analyzes phone conversation information through speech recognition, considers counterpart information and mobile terminal state changes, and predicts follow-up actions to be executed during a call, such as displaying a keypad for alphanumeric input or activating specific applications, thereby allowing users to perform tasks without interrupting the conversation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile terminal provides limited functions during a call to maintain simplicity, then the device complexity is reduced, but the user cannot perform additional tasks like checking schedules or messages without disrupting the conversation
Solution Approach 1:
The system performs speech recognition and analysis during the call to predict what actions the user will need to perform afterward, and prepares these actions in advance. For example, if the user mentions checking a schedule during the call, the system proactively displays the calendar application ready for execution, allowing the user to complete tasks without interrupting the conversation flow
Solution Approach 2:
The mobile terminal automatically analyzes the conversation content and autonomously determines appropriate follow-up actions without requiring explicit user commands. The system self-manages the prediction and execution of tasks such as displaying messages, opening applications, or setting reminders based on contextual understanding of the call content
2Ease of operation
If the mobile terminal enables speech recognition and analysis during calls, then the user experience is improved through automated follow-up actions, but the energy consumption increases
Solution Approach 1:
The system applies speech recognition selectively rather than continuously - activating it only when specific patterns or keywords are detected that indicate potential follow-up actions are needed. This partial application of speech recognition reduces overall energy consumption while maintaining the ability to provide useful automated services during calls
3Adaptability or versatility
If the mobile terminal displays keypad for alphanumeric input during ARS call, then the call service functionality is enhanced, but the user interface complexity increases
Solution Approach 1:
The keypad interface is displayed selectively based on the call type - specifically activated during Automatic Route Selection (ARS) calls where alphanumeric input is required, while remaining hidden during regular voice calls. This localized application of the keypad function enhances ARS service capability without adding unnecessary interface complexity to other call types

AI summary
An apparatus and method for processing call services in a mobile terminal are provided. The method for processing call services in a mobile terminal includes entering into, when a call is generated, a call handling mode, recognizing and analyzing voice signals sent and received in the call to produce speech analysis information, detecting a state change of the mobile terminal using a sensing unit to produce user behavior information, and predicting, when a state change of the mobile terminal is detected, an application corresponding to the speech analysis information, and activating the application as a follow-up service.
