SUBSCRIBER ATTRIBUTE BASED USER PLANE FUNCTION (UPF) SELECTION IN WIRELESS COMMUNICATION NETWORKS

Abstract

Various embodiments include a system that comprises Session Management Function (SMF). The SMF transfers a policy create request to a Policy Control Function (PCF) in response to receiving a Protocol Data Unit (PDU) session create request for a user device from an Access and Mobility Management Function (AMF). The SMF receives a policy create response for the policy create request from the PCF. The SMF parses the policy create response to determine an application Identifier (ID) for the user device. The SMF maps the application ID to a User Plane Function (UPF) ID. The SMF selects a UPF to serve the user device based on the mapping. The SMF transfers a session request to the UPF to establish a PDU session for the user device.
