AI Technical Summary

Technical Problem

In wireless cellular communications, incomplete or insufficient filter information is often sent in preliminary Authorization Authentication Requests (AARs) to Session Management Functions (SMF), leading to potential disruptions in policy control and session management procedures.

Method used

A Policy Control Function (PCF) is used to distinguish between preliminary and final AARs by examining filter information parameters such as IP address, port numbers, and status. The PCF suppresses sending update-notify messages to the SMF until complete filter information is received in the final AAR.

Benefits of technology

This approach ensures that the SMF receives accurate and complete filter information, preventing disruptions in policy control and session management, and enabling efficient resource allocation and improved user experience.

Abstract

The method(500) handles a request in a network to addresses an issue of sending incomplete or insufficient filter information in an authorization authentication request (AAR). The method comprises receiving(502), by a policy control function (PCF), an AAR request that includes the filter information from a network node of the network. The method comprises determining(504), by the PCF, whether the AAR request meets a predefined set of criteria. If the AAR request meets the predefined set of criteria, the method allows the PCF to communicate(506) an update-notify message towards a session management function (SMF). If the AAR request does not meet the predefined set of criteria, the method allows the PCF to suppress communicating(508) an update-notify message towards the SMF.
