Home Hub Protocol Translation for IMS Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy devices, such as home telephones, often lack support for Internet Protocol Multimedia Subsystem (IMS) services due to limited protocol support and device capabilities, preventing them from accessing advanced telecommunication services like VoIP and multimedia communications.
Innovation Solution
A data communication gateway, or 'home hub,' acts as a bridge between legacy devices and IMS networks, translating protocols like SIP, XML, and RTP into formats supported by these devices, enabling non-SIP enabled clients to access IMS services by registering and forwarding content to compatible devices within the home network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy devices use traditional wired telephone infrastructures, then they maintain simple device architecture and ease of operation, but they cannot access IMS services due to lack of SIP protocol support
Solution Approach 1:
The home hub acts as an intermediary device between legacy telephones and the IMS network. It performs protocol translation by converting SIP messages from the IMS network into formats compatible with legacy devices (such as HTTP or custom protocols), and vice versa. This allows legacy devices to access IMS services without requiring native SIP support, resolving the contradiction by adding adaptability through a mediating infrastructure rather than modifying the legacy devices themselves.
2Adaptability or versatility
If home hub performs protocol translation for non-SIP devices, then IMS service accessibility is improved, but network communication complexity increases
Solution Approach 1:
The home hub is designed as a universal platform that supports multiple communication protocols simultaneously (SIP, HTTP, and legacy telephone protocols). It provides multi-functional capabilities including protocol translation, message routing, service registration, and content forwarding. This universal design allows a single device to handle diverse communication requirements, improving adaptability while consolidating complexity into one multifunctional gateway rather than requiring separate systems for each protocol.
3Adaptability or versatility
If legacy devices lack SIP implementation support, then they maintain simple device capabilities and ease of manufacture, but they cannot participate in IP-based multimedia communication sessions
Solution Approach 1:
The home hub serves as a protocol mediation layer that enables legacy devices to participate in VoIP and multimedia sessions without requiring SIP implementation. It translates SIP session initiation, modification, and termination messages into commands that legacy devices can understand and execute, allowing them to join IP-based multimedia communication sessions while maintaining their simple manufacturing architecture.
4Ease of operation
If home hub registers and forwards content for non-SIP clients, then service accessibility for all devices is improved, but message routing complexity increases
Solution Approach 1:
The home hub combines multiple functions into a unified message routing system: service registration, message reception, protocol translation, and content forwarding are all integrated into single processing logic. It maintains a registration database mapping legacy device identifiers to their corresponding SIP addresses and capability profiles, then uses this consolidated information to route messages appropriately. This merging of functions provides a unified access interface for users while consolidating routing complexity into centralized management rather than distributed complexity.

AI summary
Systems and methods for home hub for IMS/Web services interaction are described. In one aspect, a data communication gateway operating as a home hub includes a processor that executes computer program instructions to provide IMS/Web services interaction to one or more client computing devices. The client computing device(s) are operatively coupled to the home hub. The client computing device(s) are not Session Initiation Protocol (SIP)-enabled devices. To provide SIP- or IMS-based services to such client computing devices, the home hub registers on behalf of the client computing device(s) to a SIP network. The home hub replies to SIP messages on behalf of the SIP network registered device(s) to process all SIP request(s) and provide the registered device(s) with corresponding SIP-based service(s).
