Global Roaming Application Server All-IP Network Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional communication networks face challenges in providing seamless global roaming across disparate networks, especially for users with multiple identities or devices operating in all-IP networks using different protocols, making it difficult to establish communication sessions independently of the user's current network.
Innovation Solution
An application server operates to receive IP-based messages, generates modified messages based on routing values, and establishes signaling links between users across all-IP and non-IP networks by determining user locations and routing values, enabling communication across different network protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication networks are used for global roaming, then users can maintain connectivity across different networks, but the complexity of managing multiple identities and protocols increases significantly
Solution Approach 1:
The patent introduces a home network as an intermediary layer that mediates between the user's multiple identities and the various visited networks. The home network maintains user profiles and routing information, acting as a central coordinator that simplifies the complexity of managing multiple network identities while ensuring reliable connectivity across different networks.
Solution Approach 2:
The home network is designed with multi-functional capabilities, serving as a universal platform that handles user authentication, profile management, message routing, and protocol translation. This universal approach consolidates multiple functions into a single system, reducing overall network management complexity while maintaining reliable global roaming.
2Adaptability or versatility
If users operate devices in all-IP networks with multiple identities, then service flexibility and user accessibility improve, but the difficulty of establishing communication sessions across disparate networks increases
Solution Approach 1:
The system performs preliminary actions by pre-registering user identities and contact information in the home network before actual communication occurs. User profiles containing multiple identities and routing information are established in advance, enabling the home network to quickly resolve and establish communication sessions across disparate networks without real-time complexity.
Solution Approach 2:
The home network implements feedback mechanisms where routing information and user location data are continuously updated and maintained. When a user moves between networks, the home network receives feedback about the user's current network location and adjusts routing accordingly, simplifying session establishment across different network types.
3Ease of operation
If seamless global roaming is implemented across all-IP and non-IP networks, then user accessibility is enhanced, but the need for protocol conversion and routing management increases system complexity
Solution Approach 1:
The home network serves as a protocol conversion intermediary between all-IP and non-IP networks. It translates messages and signaling protocols between different network types, shielding users from protocol complexity while enabling seamless communication. The home network handles protocol conversion centrally, reducing the complexity burden on individual devices and networks.

AI summary
A Global Roaming Application Server is adapted to act as an intermediary between all Internet Protocol (IP)-based network(s) and non-IP-based network(s), such as a circuit-switched landline network, an ANSI-41 network, wireless LAN network, a Global System for Mobile Communications network or Universal Mobile Telecommunications System network. In a first or forward direction, the Application Server enables a user in a non-IP network to be located in accordance with user profiles at the request of another user who has chosen to send a message via an all-IP based network. After the user in the non-IP network is so located, the Application Server enables a signaling link to be created between the two users. The Application Server may also be used to enable a signaling link when a message is sent in a second, or reverse direction.
