IMS HSS Self-Provisioning Subscriber Data Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for provisioning a Home Subscriber Server (HSS) with IMS subscriber data in cellular mobile telecommunication networks are costly and hinder the rapid introduction of new services, as they require explicit user input and manual administration, which can lead to errors and increased operational costs.
Innovation Solution
The HSS automatically provisions itself with IMS subscriber data during the user's first registration, reducing the need for explicit provisioning steps and minimizing the amount of information required, by leveraging pre-configured configuration data and authentication mechanisms within the access network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator's Customer-Care-Center creates the IMS subscription data in the HSS before the subscriber is able to register, then the HSS is provisioned with complete subscriber-related information, but the operation costs increase and the service introduction becomes slower
Solution Approach 1:
The HSS is pre-configured with templates and parameters for subscriber data creation. When a new subscriber registers, the HSS automatically generates the complete IMS subscription data using these pre-prepared templates, eliminating the need for manual provisioning while ensuring data completeness.
Solution Approach 2:
The HSS automatically provisions itself with subscriber data during the registration process. The system uses the subscriber's identity information from the registration request to automatically create and store the IMS subscription data without requiring external intervention from the Customer-Care-Center.
2Productivity
If the user triggers the provisioning by providing information via an operator's web site, then the service introduction becomes faster, but the information may be erroneous and requires careful cross-checking
Solution Approach 1:
The HSS acts as an intermediary that receives the subscriber's identity information from the registration request and automatically processes it through standardized algorithms to generate the IMS subscription data. This eliminates the need for manual cross-checking while ensuring data accuracy through systematic processing.
Solution Approach 2:
The HSS automatically validates and processes the subscriber information provided during registration. The system uses predefined rules and algorithms to ensure data accuracy without requiring manual verification, thus maintaining both speed and reliability.
3Reliability
If explicit provisioning steps are required for IMS service introduction, then the HSS is properly configured with subscriber data, but the administration costs increase and the process becomes more complex
Solution Approach 1:
The HSS automatically performs the provisioning function itself during the registration process. The system retrieves the subscriber's identity information, generates the IMS subscription data using pre-configured templates, and stores it in the database without requiring external provisioning operations, thus simplifying the overall process while ensuring correctness.
Solution Approach 2:
The HSS combines multiple functions into a single automated process: it acts as both the registration authority and the provisioning system. The same HSS that authenticates subscribers also automatically creates and manages their subscription data, eliminating the need for separate provisioning infrastructure and procedures.

AI summary
A method for self-provisioning of subscriber data allows efficient registration of a subscriber for an Internet-Protocol Multimedia Subsystem of a telecommunication network at the subscriber database of the Internet-Protocol Multimedia Subsystem. A subscription entry is created in the subscriber database of the Internet-Protocol Multimedia Subsystem of a telecommunication network, based on prior secure identification of the subscriber by the access network that grants access to the Internet-Protocol Multimedia Subsystem.
