Subscriber Access Network Profile Configuration via ID Referencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing subscriber access network profile configuration in TISPAN NGN architecture occupies a large amount of memory space and network bandwidth due to the inclusion of QoS profile information and initial gate settings, which are repetitive and not efficiently managed across functional entities.
Innovation Solution
The solution involves separating the QoS profile information and initial gate settings from the subscriber access network profile, storing them in dedicated tables (QoS Profile Information Table and Initial Gate Setting Table) within the CLF and RACS, and using IDs to reference these profiles, allowing multiple subscribers to share the same settings, thereby reducing data storage and transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoS profile information and initial gate settings are included in every subscriber access network profile, then complete subscriber configuration is achieved, but memory space and network bandwidth are excessively occupied
Solution Approach 1:
The subscriber access network profile is segmented into two parts: a compact profile identifier (stored in each subscriber profile) and detailed QoS/profile information (stored centrally in a profile database). This segmentation allows complete configuration data to be referenced without duplicating it across all subscriber profiles, thereby reducing memory space and network bandwidth requirements while maintaining configuration completeness.
Solution Approach 2:
Instead of copying complete QoS profile information and initial gate settings into every subscriber access network profile, the invention uses profile identifiers that reference the actual configuration data stored in a centralized profile database. This copying approach replaces redundant data duplication with efficient referencing, significantly reducing the quantity of data stored and transmitted.
2Reliability
If complete subscriber access network profiles are transmitted across network interfaces, then accurate subscriber configuration is ensured, but network bandwidth resources are consumed
Solution Approach 1:
The invention extracts the detailed QoS profile information and initial gate settings from individual subscriber access network profiles and places them in a centralized profile database. Only compact profile identifiers are transmitted across network interfaces between functional entities like NACF, CLF, and RACS. This extraction maintains configuration accuracy through centralized storage while dramatically reducing bandwidth consumption during profile transmission.
3Adaptability or versatility
If profile data is stored in multiple functional entities, then access flexibility is improved, but hardware costs increase due to redundant storage requirements
Solution Approach 1:
The invention merges the storage of detailed QoS profile information and initial gate settings into a single centralized profile database, while allowing multiple functional entities (NACF, CLF, RACS) to access this centralized storage. This merging eliminates redundant storage across multiple entities, reducing hardware costs and device complexity while maintaining access flexibility through the centralized database interface.

AI summary
A method and a device for configuring a subscriber access network profile are provided. The method includes the following steps. Firstly, a connectivity session location and repository function (CLF) receives a message carrying a profile information identity (ID). Then, the CLF finds profile information corresponding to the profile information ID according to the profile information ID in the message.
