METHOD AND SYSTEM FOR POLICY CONTROL FUNCTION SELECTION SERVICE

Abstract

A method, an end device, and a non-transitory computer-readable storage medium are described in relation to a policy control function (PCF) selection service. The PCF selection service may include storing context information, which includes data indicating identifiers associated with a selected PCF or SM-PCF, with a unified data storage device. The context information may be used by session management functions (SMFs) of the same or different SMF set. The PCF selection service may include storing subscription data of an end device indicating that the same PCF set or the same session management (SM)-PCF set are to be selected for all packet data unit sessions of the end device. The PCF selection service may enable an access and mobility management function to provide the context information to an SMF or the SMF may obtain the context information locally or from the unified data storage device.
