Assisted Dialing System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile users face difficulties in dialing numbers correctly when roaming across different countries due to varying international dialing standards and network technologies, leading to inconvenience as they need to manually adjust IDD codes and country codes, which can be confusing and error-prone.
Innovation Solution
A method is implemented in mobile devices to automatically identify the user's location and modify dialing numbers accordingly by adding or replacing IDD codes and country codes based on the device's current country and network technology, ensuring correct international and domestic dialing without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual dialing with user awareness of IDD codes is required, then dialing accuracy can be maintained, but user convenience and ease of operation deteriorate significantly
Solution Approach 1:
The mobile device automatically performs dialing code selection and number formatting without requiring user knowledge or manual intervention. The system self-adjusts IDD codes, country codes, and number formats based on detected location and network type, making the dialing process as simple as entering the destination number alone.
Solution Approach 2:
The system dynamically changes dialing parameters (IDD code, country code, number format) based on detected location and network technology. When the device detects a change in country or network type, it automatically adjusts the dialing parameters to match the appropriate standards for that region and technology.
2Ease of operation
If automatic dialing assistance is implemented, then ease of operation improves, but device complexity increases due to location detection and number modification logic
Solution Approach 1:
The system uses the mobile device's existing location detection capabilities (GPS, network-based location) as an intermediary to automatically determine the appropriate dialing standards. This intermediary approach allows the system to bridge the gap between user input and network requirements without complex manual intervention.
Solution Approach 2:
The dialing assistance system leverages existing multi-functional capabilities of modern mobile devices (location detection, network identification, automatic number formatting) to provide comprehensive dialing support across multiple countries and network technologies through a single integrated feature.
3Adaptability or versatility
If users must manually adjust IDD codes when roaming, then adaptability to different networks can be achieved, but time consumption and productivity deteriorate
Solution Approach 1:
The system performs preliminary detection of location and network type automatically upon device activation or when entering a number, and pre-configures the appropriate dialing parameters before the user needs to place a call. This eliminates the need for users to manually adjust settings when roaming.
Solution Approach 2:
The system continuously monitors location and network type changes, and automatically adjusts dialing parameters in real-time based on this feedback. When the device detects a change in country or network technology, it immediately updates the dialing configuration to maintain compatibility without user intervention.

AI summary
The instant application describes a method for enabling an assisted dialing On a mobile device. The method includes steps of receiving, at a mobile device, a number; automatically identifying a reference country and one or more parameters associated with the reference country; and automatically determining whether the received number should be modified based on the one or more parameters associated with the reference country. The method also includes steps of automatically modifying the received number upon determining that the received number should be modified; and transmitting the modified number to a wireless network servicing the mobile device_
