Unified Data Repository for Policy Control Association Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of managing policy control associations in wireless communication networks, particularly in next-generation networks like 5G, is exacerbated by the need for efficient exchange of access management, user equipment, and session management policy data, which current systems struggle to handle effectively, leading to increased network complexity and signaling overhead.
Innovation Solution
The implementation of a unified data repository function and Nudr interface allows for the retrieval of policy control-related subscription information and application-specific data for access management, user equipment, and session management policy data in fewer signaling exchanges, enabling efficient establishment of policy control associations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate AM PCF, SM PCF, and UE PCF are deployed independently, then access management, session management, and UE policy control can be handled independently, but the complexity of exchanging policy data between these separate functions increases
Solution Approach 1:
The patent introduces a unified data repository function as an intermediary component that centralizes the storage and management of policy data. This mediator enables the separate AM PCF, SM PCF, and UE PCF functions to independently access required policy data through standardized interfaces, eliminating the need for complex direct data exchange between these separate policy control functions while maintaining their operational independence
2Ease of operation
If traditional separate data retrieval methods are used for AM, UE, and SM policy data, then each policy type can be managed separately, but the number of signaling exchanges required increases
Solution Approach 1:
The patent merges the retrieval operations for AM policy data, UE policy data, and SM policy data into a single unified data repository function. This consolidation allows multiple policy data types to be accessed through a centralized location, reducing the number of separate signaling exchanges required while maintaining the ability to manage each policy type independently through standardized access interfaces

AI summary
Methods, devices, and computer-readable mediums may provide receiving, at a request to establish an access and mobility (AM) policy control association in relation to an establishment of a data session requested by a user associated with a user equipment (UE) device; generating a query to a network device via a network interface, for AM policy control data and for at least one of UE policy control data or session management (SM) policy control data; receiving the AM policy control data and the at least one of the UE policy control data or the SM policy control data from the network device, creating the AM policy control association based on the received AM policy control data; and storing the at least one of the UE policy control data or the SM policy control data.
