VoIP Service Coupling via IMS and FMC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers with both landline and mobile network contracts from the same provider face difficulties in seamlessly integrating and using VoIP services across these networks, lacking a simplified and unified solution for voice communication.
Innovation Solution
A method and system that enable VoIP service coupling between mobile and fixed networks by using a mobile phone device to set up an Internet connection via a WLAN of the landline connection, registering with the IMS using a SIM card, and verifying the IP address assignment to ensure seamless communication across both networks, leveraging existing contracts through FMC components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VoIP services are implemented separately for mobile and fixed networks, then each network can operate independently, but integration and seamless communication between networks becomes complex and difficult
Solution Approach 1:
The patent merges mobile and fixed network VoIP services into a unified system where a single IMS core handles both network types. The FMC component couples the mobile network connection with the fixed network connection, allowing seamless integration where calls can be routed between networks without requiring separate independent systems.
Solution Approach 2:
The IMS core is designed as a universal platform that provides VoIP services to both mobile and fixed networks through a single infrastructure. The system can handle calls from mobile phones, landlines, and the integration between these networks, making the system multi-functional and adaptable to different communication scenarios.
2Adaptability or versatility
If IP addresses are dynamically assigned in mobile networks, then users can move freely between locations, but permanent assignment of telephone numbers to IP addresses becomes impossible
Solution Approach 1:
The FMC component acts as an intermediary between the mobile network and fixed network, maintaining the dynamic IP address assignment of mobile networks while enabling reliable telephone number mapping. It couples the mobile connection with the fixed network connection, allowing the system to resolve the contradiction between dynamic mobility and stable number mapping.
3Reliability
If additional authentication is required for VoWiFi, then security is improved, but user convenience and ease of connection is reduced
Solution Approach 1:
The system performs authentication preliminarily through the FMC component when coupling mobile and fixed networks. By establishing the coupling relationship in advance, the system can reuse existing authentication mechanisms without requiring additional user interaction during the actual VoWiFi connection process, thus maintaining security while preserving convenience.

AI summary
The present invention relates to a method for coupling VoIP services from a user's mobile phone connection in a mobile network and a user's fixed-line connection, wherein the mobile phone connection and the user's fixed-line connection are provided by one and the same provider, wherein the user establishes an internet connection with an assigned mobile terminal device (20) via a WLAN of an integrated access unit (11) of his fixed-line connection and authenticates and registers himself as a VoWiFi user (U2) with an IMS of the mobile network (25) using an assigned SIM card via the internet connection, wherein the mobile network (25) receives an IP address assigned to the integrated access unit (11) of the fixed-line connection.The invention checks this system with regard to its assignment to a fixed-line connection and, after verifying the assignment of the IP address to the user's fixed-line connection, registers the user as a fixed-line user (U1) belonging to the VoWiFi user (U2). Furthermore, the present invention relates to a corresponding system.
