A network repository function unit registers a session management function unit. The session management function unit initiates a session in response to a session request from a user equipment. The session management function unit accesses a subscriber profile stored by a data management unit, and the subscriber profile includes one or more content filtering settings. In response to the session being established, the session management function unit is configured to determine data packets for the user equipment to be filtered based on the one or more content filtering settings. Absent triggering an instruction to be sent via a Gx interface, an access and mobility management function (AMF) unit is configured to select the session management function unit in compliance with the one or more content filtering settings for filtering the data packets for the user equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Content filtering for packet data network gateway (PGW) and session management function (SMF) selection","description":"A method and system for content filtering.
