Solution Overview

Problem

Users are reluctant to discontinue landline telephone services due to the desire to maintain existing phone numbers and home phones as primary communication methods, despite the proliferation of wireless voice and internet services, especially in areas where landline services are unavailable.

Innovation Solution

A mobile convergence terminal that connects to a plain old telephone service (POTS) phone, enabling conversion between POTS calls and wireless VoIP calls, and controlling mobile phones via NFC to provide a seamless communication experience, allowing users to initiate either wireless calls based on input from the POTS phone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users discontinue landline telephone services to use wireless services, then wireless service availability is improved, but users lose the ability to maintain existing phone numbers and home phones as primary communication methods

Engineering Contradiction:

Improvewireless service availabilityVSAvoidmaintenance of existing phone numbers and home phones

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines landline telephone service and wireless service into a single integrated system. The mobile convergence terminal merges POTS interface functionality with cellular modem capabilities, allowing users to maintain their home phone as the primary communication device while gaining wireless service through the same device. This merging resolves the contradiction by enabling both landline number portability and wireless service availability simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mobile convergence terminal is designed as a universal device that performs multiple functions: it provides POTS telephone service, cellular wireless service, and internet connectivity through a single device. The terminal can function as both a traditional landline phone and a mobile phone, allowing users to maintain their existing phone numbers while accessing wireless services, thus resolving the contradiction between service availability and ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If users maintain landline telephone services, then existing phone numbers and home phones are preserved, but wireless service availability is reduced

Engineering Contradiction:

Improvemaintenance of existing phone numbers and home phonesVSAvoidwireless service availability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent integrates landline and wireless services into a single convergence terminal that provides both POTS and cellular capabilities. This merging allows users to maintain their existing phone numbers and home phones while simultaneously gaining wireless service availability, resolving the contradiction by making both services available through one unified system.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If a mobile convergence terminal provides multiple call types (POTS, VoIP, mobile calls), then communication versatility is improved, but device complexity increases

Engineering Contradiction:

Improvecommunication versatilityVSAvoidterminal structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple communication functions (POTS telephone service, VoIP capabilities, and cellular wireless service) into a single integrated terminal. By combining these functions at the hardware and software levels, the device achieves high communication versatility while managing complexity through unified architecture rather than separate systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mobile convergence terminal is designed as a universal communication device that handles multiple call types (POTS, VoIP, and mobile calls) through a single platform. This multi-functionality approach allows the terminal to provide diverse communication capabilities while avoiding the complexity of multiple separate devices by using shared processing and communication interfaces.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mobile convergence terminal is disclosed. In one aspect, the terminal includes a subscriber line interface configured to communicate with a plain old telephone service (POTS) phone and generate a first POTS call based on an input to the POTS phone. The terminal also includes a processor configured to selectively initiate a first type of wireless call or a second type of wireless call based at least in part on the input to the POTS phone and the first POTS call, wherein the first and second types of wireless call are different from each other.
