Automated IMS Permission Provisioning via HSS Sh Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the IP multimedia subsystem (IMS) environment, there is a lack of automated and efficient mechanism for provisioning permissions between application servers and user data, leading to manual processes for managing interactions and permissions, which are inefficient and prone to errors.
Innovation Solution
An automated system that includes a Home Subscriber Server (HSS) logic, permissions database, and user database, utilizing the Sh protocol to manage permissions through automated discovery, learning, and provisioning of permissions records, allowing controlled interactions between application servers and user data based on predefined permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used for managing interactions and permissions between application servers and user data, then system complexity is reduced, but productivity and efficiency deteriorate due to manual intervention being time-consuming and error-prone
Solution Approach 1:
The system enables automatic self-provisioning of permissions through the Sh interface. When an application server communicates with the HSS, the system automatically discovers the server, learns its requirements, and provisions appropriate permissions without manual intervention. This self-service mechanism resolves the contradiction by automating permission management while maintaining system structure through standardized protocols.
Solution Approach 2:
The system performs preliminary actions by establishing a permissions database structure in advance and pre-defining the Sh interface protocols. This preliminary setup enables automatic permission provisioning to occur seamlessly when application servers connect, improving productivity without requiring complex real-time decision-making mechanisms.
2Productivity
If automated mechanisms are implemented for provisioning permissions, then productivity and efficiency improve, but device complexity increases due to additional system components and protocols
Solution Approach 1:
The HSS is designed with multi-functionality, serving both as a home subscriber server and as an automatic permission provisioning system. The Sh interface provides universal communication capabilities between the HSS and application servers, enabling automated permission management without requiring separate dedicated systems. This universality reduces overall system complexity while maintaining high automation levels.
Solution Approach 2:
The Sh interface acts as an intermediary protocol layer between the HSS and application servers. This standardized interface simplifies the automation mechanism by providing a uniform communication channel, reducing the complexity that would otherwise arise from multiple proprietary interfaces and integration points.
3Reliability
If manual permission management is used, then system security may be maintained through human oversight, but reliability deteriorates due to human errors in manual processes
Solution Approach 1:
The automatic permission provisioning system eliminates human intervention in the permission assignment process, thereby removing human errors while maintaining security. The system autonomously discovers application servers, determines their requirements, and provisions appropriate permissions through the Sh interface, ensuring both high reliability and ease of operation.
Solution Approach 2:
The system implements feedback mechanisms where the HSS monitors application server communications through the Sh interface and automatically adjusts permissions based on observed behavior and requirements. This continuous feedback loop ensures accurate permission provisioning while simplifying operation, as the system self-corrects without manual oversight.

AI summary
Systems, methodologies, media, and other embodiments associated with provisioning an Internet Protocol (IP) core network services multimedia subsystem (IMS) are described. One exemplary system embodiment includes a Home Subscriber Server (HSS) logic operably connectable to components including, a user database, an application server (AS), and a permissions database. The HSS logic may be a component of an IMS that facilitates communications between application servers and users. Thus, the HSS logic may be configured to receive an AS-to-user-database-interface-message (AUDIM) and to selectively update the permissions database based, at least in part, on the AUDIM. The user database may store user data concerning IMS users and the permissions database may store information for controlling AUDIM initiated interactions between an AS and the user database.
