Caller ID Delivery to IPTV via Media Gateway Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems lack a means to provide caller identification services from telephony networks to Internet Protocol Television (IPTV) devices, especially for subscribers using both cellular and IP-based services.
Innovation Solution
A method and system that receive a communication request from a caller device, map the called party number to an Internet Protocol-enabled device address, and send the caller party number to the corresponding IPTV device address, enabling caller identification services across voice networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If caller identification services are implemented for traditional telephony networks, then caller identification information can be provided to telephony devices, but there is no means to provide caller identification information to IPTV devices
Solution Approach 1:
The patent introduces a media gateway as an intermediary component that bridges the telephony network and IP network. The media gateway receives caller identification information from the telephony network via SS7 signaling, translates it into IP-compatible formats, and forwards it to IPTV devices. This intermediary resolves the incompatibility between traditional telephony protocols and modern IP-based networks, enabling caller ID delivery to IPTV devices without losing the information.
Solution Approach 2:
The patent creates a universal caller identification system that can serve multiple types of devices simultaneously. By implementing a dual-network architecture that handles both traditional telephony (PSTN/ cellular) and IP-based networks (IPTV), the system provides caller identification services universally across different device types and network protocols, eliminating the limitation where IPTV devices could not receive caller ID information.
2Reliability
If separate networks are used for telephony and IPTV services, then each network can operate independently, but caller identification information cannot be delivered from telephony network to IPTV devices
Solution Approach 1:
The patent merges the telephony network and IP network through a media gateway that operates at the intersection of both networks. This gateway combines the signaling capabilities of SS7 (telephony) with IP protocol support, creating a unified communication path that allows caller identification information to flow from telephony devices through the gateway to IPTV devices while maintaining the operational independence of each network infrastructure.
3Reliability
If traditional telephony protocols are used, then established caller identification services work for telephony devices, but the system cannot deliver caller identification to Internet Protocol-enabled devices
Solution Approach 1:
The patent changes the protocol parameters at the media gateway by translating SS7 signaling messages (used in traditional telephony) into IP-compatible signaling formats. This parameter transformation allows the same caller identification information to be reliably transmitted across different protocol domains, maintaining service reliability for telephony devices while enabling compatibility with IP-based IPTV devices through format conversion.

AI summary
A method, system, and computer program product for providing caller identification services to an Internet Protocol-enabled device are provided. The method includes receiving a communication request from a caller device over a voice network, the communication request including a caller party number, mapping a called party number to an Internet Protocol-enabled device address of a called party, and sending the caller party number to the Internet Protocol-enabled device address corresponding to the called party number.
