Solution Overview

Problem

Traditional telephony devices lack speed dialing capability in IP communication environments, making it difficult for users with traditional equipment to initiate calls over IP networks, especially when addresses include alphanumeric characters.

Innovation Solution

A terminal adaptor and calling party proxy system that recognizes speed dial codes from traditional telephony devices, translating these codes into corresponding IP addresses or URLs to facilitate calls over packet networks, enabling speed dialing functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional telephony devices are coupled to IP network via terminal adaptor, then traditional telephone sets can be used in IP network environment, but speed dialing functionality is lost

Engineering Contradiction:

Improvecompatibility of traditional telephone with IP networkVSAvoidspeed dialing capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a calling party proxy as an intermediary component between the terminal adaptor and the IP network. This proxy intercepts speed dial codes from the traditional telephone, translates them into corresponding IP addresses or URLs, and initiates sessions on behalf of the telephone. This mediator enables speed dialing functionality to work across the interface between traditional telephony and IP networks without requiring changes to the traditional telephone itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If alphanumeric addressing is used in IP networks, then flexible hierarchical addressing is achieved, but dialing complexity increases

Engineering Contradiction:

Improveaddressing flexibilityVSAvoiddialing operation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the dialing process into two distinct parts: the user input stage where simple numeric speed dial codes are entered, and the translation stage where the calling party proxy converts these codes into complex alphanumeric IP addresses or URLs. This segmentation allows the complexity of alphanumeric addressing to be handled by the system infrastructure rather than requiring the user to directly input or manage complex address formats.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary translation of speed dial codes into full IP addresses or URLs before actual call initiation. The calling party proxy pre-resolves the abbreviated speed dial code into the complete alphanumeric address format required by the IP network, so that when the call is initiated, the complex addressing work has already been completed in advance.

Inventive Principle:

Principle #10Preliminary action

AI summary

The present invention provides speed dial capability for traditional telephones, which are coupled to a terminal adaptor to facilitate calls over a packet network. In operation, the terminal adaptor will receive a speed dial code, such as 12#, from a traditional telephone and use the speed dial code to attempt to initiate a session over the packet network. A proxy will intercept the session request, recognize the speed dial code in the session request, and access an address associated with the speed dial code. The proxy will then use the address corresponding to the speed dial code to initiate a session between the terminal adaptor and another device to facilitate the call. The terminal adaptor will provide the necessary translation between the packet network and the traditional telephony interface to which the traditional telephone is coupled.
