PCF Registration via IMEI TAC Database Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks inefficiently register User Equipment (UE) with the Policy Control Function (PCF) and fail to effectively inhibit PCF registration for devices lacking the capability to enforce rules provided by the PCF.
Innovation Solution
The proposed solution involves selectively registering UE with the PCF based on the International Mobile Equipment Identity Type Allocation Code (IMEI TAC) by comparing the IMEI TAC of the UE to a database, thereby determining when PCF registration is available and transferring an equipment identity check response to the control plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AMF performs PCF registration for all devices registering on the network, then all user devices are registered with the PCF, but excessive signaling is generated towards the PCF which degrades its performance
Solution Approach 1:
The AMF performs preliminary capability determination by checking the device type indication before initiating PCF registration. This preliminary action filters out devices that do not support PCF registration, preventing unnecessary signaling while ensuring complete registration for capable devices.
Solution Approach 2:
The system applies different registration behavior based on device capabilities. Capable devices receive full PCF registration treatment while non-capable devices are excluded, creating localized quality differentiation in the registration process to optimize PCF performance.
2Adaptability or versatility
If the AMF performs PCF registration for all devices, then network coverage is maximized, but unnecessary registrations result in excessive signaling which degrades PCF performance
Solution Approach 1:
The AMF performs preliminary capability assessment by examining device type indications before initiating PCF registration procedures. This preliminary action identifies devices that do not support PCF registration and excludes them from the registration process, reducing signaling overhead while maintaining coverage for capable devices.
Solution Approach 2:
The system extracts and removes non-capable devices from the PCF registration process. By identifying and separating devices that lack PCF registration capability, the system eliminates unnecessary signaling while preserving full network coverage for devices that can benefit from PCF services.

AI summary
Various embodiments comprise a wireless communication network to qualify user devices for network policy association. In some examples, the wireless communication network comprises a network data system. The network data system receives an equipment identity check request transferred by a control plane that comprises an International Mobile Equipment Identifier (IMEI) for a User Equipment (UE). The network data system reads the IMEI to determine a Type Allocation Code (TAC) for the UE. The network data system compares the TAC for the UE to an IMEI TAC database indicating when Policy Control Function (PCF) registration is available for the UE and determines when the PCF registration is when is available for the UE. The network data system transfers an equipment identity check response that indicates when the PCF registration is available for the UE to the control plane.
