IPTV Telephony Service Gateway for Dual-Mode Handset Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing system or method to automatically deliver telephony network services from a dual mode handset to an external entity, such as an IPTV device, for display.
Innovation Solution
A system and method that detects a dual mode handset registered on a cellular network, extracts specific telephony network services data from incoming calls, and routes it to an external entity for display, using protocols like SIP messaging, without the need for a set-top box, and includes a network data store for data retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telephony network services are delivered to external entities like IPTV devices, then user experience is enhanced through seamless integration, but device complexity increases due to the need for multiple communication protocols and interfaces
Solution Approach 1:
The patent introduces a service gateway as an intermediary component that mediates between the dual-mode handset and external entities like IPTV devices. This gateway handles protocol conversion, data formatting, and service routing, thereby enabling telephony services to be delivered to external displays without requiring the handset itself to become more complex. The gateway acts as a buffer that manages the complexity externally while preserving the simplicity of the core handset device.
2Device complexity
If telephony services are displayed on external devices without a set-top box, then device requirements are reduced, but service delivery reliability may be compromised
Solution Approach 1:
The patent implements a universal service delivery architecture where the service gateway can handle multiple types of external entities (IPTV devices, smartphones, tablets) through a single interface. This multi-functional gateway maintains service delivery reliability by providing consistent service routing and protocol adaptation regardless of the target device, eliminating the need for device-specific set-top boxes while preserving reliable service delivery through standardized processes.
3Adaptability or versatility
If dual mode handsets are used to enable both cellular and IP network communications, then service versatility is improved, but device complexity increases
Solution Approach 1:
The patent segments the communication functionality into distinct modes (cellular and IP-based) that can be independently managed within the dual-mode handset. The service gateway further segments the service delivery path, routing different types of telephony services through appropriate protocols. This segmentation allows the handset to maintain versatility across network types while managing complexity through modular, protocol-specific handling rather than requiring a single complex unified interface.

AI summary
A system that automatically delivers telephony network services from a dual mode service technology platform to an external entity. The system includes a sensing component that detects the presence of a mobile handset registered on a cellular network, and registers the mobile handset with a wireless access network. Further, a provisioning component identifies calls to subscribers that are provisioned for the requested telephony network service. Once the calls are identified, the provisioning component extracts the requested data from the incoming calls and routes the data to an external entity for display.
