Mobile Contact Selection for Landline Calling via Near-Field Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not allow a user to conveniently select a contact from a cell phone contact list and complete the call on a different communication device, such as a landline phone, despite potential advantages like better voice quality and volume.
Innovation Solution
A telephony system using a primary digital communication device, a mobile application, and a near-field wireless network to enable the selection of a contact from a contact list on the primary device, which then causes another accessible digital communication device to place the call, potentially through a landline exchange or VoIP, leveraging near-field wireless protocols like Bluetooth or Internet connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user places a call from a cell phone through a cellular network, then the call can be made from any location, but the voice quality and volume are generally worse compared to landline devices
Solution Approach 1:
The system enables a single contact list to serve multiple communication devices (cell phone, landline, tablet, computer) for call initiation. The contact list on the primary device can trigger calls on any connected device, making the system universal across different device types and communication networks.
Solution Approach 2:
The patent introduces a server as an intermediary that receives call initiation requests from the primary device, stores the call request with the recipient's number, and then enables the secondary device to complete the call. This mediator facilitates the transfer of call functionality between devices while maintaining contact list access on the original device.
2Reliability
If a user wants to use a landline device for better voice quality, then the call must be placed directly from the landline, but the user cannot conveniently select contacts from the cell phone contact list
Solution Approach 1:
The system merges the contact list functionality of the cell phone with the call placement capability of the landline device. By connecting these devices through the server intermediary, the user experiences a unified system where contact selection on one device seamlessly transitions to call execution on another device.
Solution Approach 2:
The server acts as a mediator that bridges the cell phone and landline device, allowing the user to select contacts on the cell phone while the landline device executes the call. This intermediary maintains the convenience of mobile contact management while enabling landline call quality.
3Adaptability or versatility
If a user connects multiple digital communication devices to enable flexible call completion, then the adaptability increases, but the device complexity and network configuration requirements increase
Solution Approach 1:
The system is designed to work with multiple types of communication devices (cell phones, landlines, tablets, computers) through a universal server interface. Each device type maintains its native functionality while being integrated into the unified call system through the server, reducing the need for device-specific configuration complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to initiate calls from a cell phone contact list on a preferred device, such as a landline, ensuring better voice quality and flexibility in call completion.
Implementation Method 1
a near-field wireless network coupling the primary digital communication device and the digital communication device other than the primary digital communication device
Data Source
AI summary
A telephony system has a primary digital communication device associated with a caller, the primary digital communication device executing a mobile application, a digital communication device accessible to the user other than the primary digital communication device, and a near-field wireless network coupling the primary digital communication device and the communication device other than the primary digital communication device. The caller, logged into the mobile application, selects a contact from a contact list in the primary digital communication device, and the mobile application, through the near-field wireless connection, causes the digital communication device other than the primary digital communication device to place the call.
