IMS Gateway Terminal Identification for Multi-User Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IMS-based IPTV systems cannot identify individual terminals attached to an IMS Gateway, preventing communication between multiple terminals.
Innovation Solution
A method and system that allocates unique global IDs to user terminals, allowing them to communicate and establish service sessions through an IMS network by transmitting service request and response messages, with an IMS Gateway managing and forwarding these IDs to a service provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple terminals are served by a single IMS Gateway in conventional IMS-based IPTV systems, then the system can support multiple user terminals, but the IMS network cannot identify individual terminals attached to the Gateway
Solution Approach 1:
The patent segments the identification function by introducing a separate terminal identification module that works in conjunction with the IMS Gateway. This module assigns and manages unique terminal identifiers (such as private IP addresses or terminal-specific IDs) for each terminal attached to the gateway, allowing individual terminal identification while maintaining multi-terminal support. The identification information is then mapped to the shared IMS public user identity, enabling both aggregation and individual recognition.
2Ease of operation
If conventional IMS-based IPTV systems use shared IMS public user identity for multiple terminals, then the system simplifies authentication, but the terminals cannot communicate with each other based on the IPTV system
Solution Approach 1:
The patent introduces terminal identification information (such as private IP addresses, terminal IDs, or device identifiers) as an intermediary layer between the shared IMS public user identity and the actual terminal devices. This intermediary enables the system to maintain the simplicity of shared authentication while simultaneously providing unique identification for each terminal, thereby enabling terminal-to-terminal communication within the IPTV system. The intermediary mapping table stores the correspondence between public identities and private terminal identifiers.
3Adaptability or versatility
If the system allocates unique global IDs to each terminal and registers them with the service provider, then terminal communication and file sharing services are enabled, but the system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-allocating terminal identification information (such as private IP addresses or terminal-specific IDs) when terminals attach to the IMS Gateway, before any communication services are initiated. The terminal identification module pre-establishes the mapping between these unique identifiers and the shared IMS public user identity in a mapping table. This preliminary setup enables subsequent communication services (file sharing, messaging, etc.) to function without requiring complex real-time identification logic during service execution.

AI summary
A service provision method in an Internet Protocol Multimedia Subsystem (IMS) network is provided. A service request message is transmitted from a first user terminal to a second user terminal for requesting a service. The service request message includes global identifiers (IDs) allocated to the first user terminal and the second user terminal. A service response message is transmitted from the second user terminal to the first user terminal. A service session is established between the first user terminal and the second user terminal, when the service response message is received by the first user terminal.
