Mobile Terminal Communication Switching Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in managing communication system switches during data communication, leading to unintended high costs due to automatic switching between different communication systems without user notification, resulting in unrecognized system changes.
Innovation Solution
A mobile terminal with modules for state management, user notification, and communication prohibition, which ensures that data communication is prohibited in one system until the user is notified and acknowledges the switch, preventing unintended high-cost data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic switching between communication systems is implemented, then communication continuity is maintained, but user awareness of system changes is lost leading to unintended high costs
Solution Approach 1:
The patent implements a notification mechanism that provides feedback to the user when automatic switching between communication systems occurs. The notification module sends alerts to inform users of the system switch, thereby maintaining communication continuity while ensuring user awareness and preventing unintended high-cost data communication.
Solution Approach 2:
The patent performs preliminary notification to the user before or at the moment of switching communication systems. By notifying the user in advance or concurrently with the switch, the system maintains reliability through automatic switching while preventing information loss about system changes through proactive user notification.
2Loss of energy
If preferential use of low-cost wireless LAN is set, then communication cost is reduced, but communication may be interrupted when moving out of range
Solution Approach 1:
The patent performs preliminary detection of communication range status and proactively switches from wireless LAN to mobile communication system before complete disconnection occurs. This preliminary switching action maintains communication continuity while managing costs by only switching when necessary, avoiding interruptions when moving out of wireless LAN range.
Solution Approach 2:
The patent implements continuous monitoring of communication range status with feedback mechanisms that detect when the mobile terminal moves out of wireless LAN range. This feedback triggers automatic switching to mobile communication system, ensuring communication continuity while maintaining cost efficiency by using the preferred low-cost system whenever available.
3Reliability
If automatic switching from wireless LAN to mobile communication is performed, then communication continuity is maintained, but unintended high-cost data communication occurs without user notification
Solution Approach 1:
The patent implements a dual-function feedback mechanism: it automatically switches communication systems to maintain continuity while simultaneously notifying the user of the switch. This feedback loop ensures communication reliability is maintained through automatic switching while user awareness is preserved through notifications, preventing unintended high-cost data communication.
Solution Approach 2:
The notification module acts as an intermediary between the automatic switching mechanism and the user. It mediates the information flow about system changes, ensuring that while automatic switching maintains communication continuity, the user is informed of cost implications through notifications, thereby preventing unintended high-cost communication.

AI summary
A mobile terminal includes a first communication module, a second communication module, a state management module configured to make an out-of-range notification when a communication state of the first communication module moves out of a communication range, a notification module configured to send a user notification as a notification indicating that the first communication module is disconnected to a user when the out-of-range notification is received, a determination module configured to determine whether or not a given process for the user notification is completed, a setting module configured to perform setting indicating that the process for the user notification is completed to the state management module when the determination module determines that the process is completed, and a communication prohibition module for prohibiting the data communication by the second communication module until the setting indicating that the process is completed is performed after the communication state of the first communication module moves out of the communication range.
