IMS Roaming Agreement Automation via Edge Proxy Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IMS roaming agreements are manually set up and managed, which is impractical for the increasing number of IMS domains, especially temporary ones, and lacks automated mechanisms for managing user registrations when a roaming agreement expires or is terminated, leading to inefficiencies in service quality and scalability.
Innovation Solution
A method for automatically managing user registrations in an IMS network by determining status changes in roaming agreements and sending roaming status update information to initiate registration updates, using edge proxies, user databases, and user registrars to handle deregistrations and updates efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual management of roaming agreements is used, then current infrastructure is simple, but scalability and adaptability to temporary IMS domains deteriorates
Solution Approach 1:
The patent implements self-service by enabling IMS networks to automatically establish, manage, and terminate roaming agreements without manual intervention. The system uses automated negotiation protocols where networks independently determine roaming parameters, exchange capability information, and manage their own registration states, thereby resolving the contradiction between adaptability and management complexity.
Solution Approach 2:
The patent introduces dynamic characteristics to roaming agreement management by enabling real-time establishment and termination of agreements based on current network conditions. The system allows temporary IMS domains to be quickly integrated and exited, with automatic detection of agreement status changes and corresponding user registration updates, making the infrastructure adaptable to transient network needs.
2Productivity
If automated roaming agreement establishment is implemented, then scalability improves, but system complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional automated management system that handles multiple tasks through standardized protocols. The same framework manages agreement establishment, parameter negotiation, user registration updates, and termination procedures, thereby improving productivity across all operations without proportionally increasing complexity through reuse of common mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms where networks continuously exchange status information about roaming agreements and user registrations. This enables automated detection of agreement changes and triggers appropriate responses such as user deregistration, maintaining high productivity through real-time updates while managing complexity through structured feedback loops.
3Speed
If manual roaming agreement management is used, then implementation is simple, but response time to traffic peaks and service updates deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring networks with capability information and roaming parameters before actual roaming occurs. This enables rapid response to traffic peaks since agreements can be automatically established without manual setup, while the ease of operation is maintained through standardized automated procedures that simplify updates and modifications.
Solution Approach 2:
The patent introduces dynamic capabilities allowing networks to automatically adjust roaming agreements in response to changing conditions such as traffic peaks. The system enables real-time updates to agreement parameters and user registrations, providing fast response speed while maintaining ease of operation through automated decision-making and execution.
4Reliability
If automated user registration management is implemented, then service quality and scalability improve, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling networks to automatically manage user registrations based on roaming agreement status changes. The system autonomously detects agreement changes, identifies affected users, and performs registration updates without manual intervention, thereby improving reliability through consistent automated execution while managing complexity through standardized self-service procedures.
Solution Approach 2:
The patent implements feedback mechanisms that continuously monitor roaming agreement status and trigger automated user registration updates accordingly. This feedback-driven approach ensures reliable synchronization between agreement status and user registrations, improving reliability while managing complexity through structured cause-effect relationships.

AI summary
Techniques for managing a registration of a roaming user terminal (116) in its IMS home network (102) based on a roaming agreement between the visited IMS network (104) and the home IMS network (102) are described. According to one embodiment of the invention, a method for managing user registrations in the first IMS network (102) is provided. The method may be performed in an I-CSCF (106) of the first IMS network and comprises the steps of determining a status change in an automatically established roaming agreement with the second IMS network; and sending, based on the determination result, roaming status update information (204) to an HSS (110) associated with the first IMS network for initiating a registration update of the user.
