Provided is a method for managing a local area data network (LADN) session, as well as a session management function (SMF) node that is capable of performing this method. The method involves determining whether to release or deactivate the LADN session of a terminal based on information received by the SMF from an access and mobility management function (AMF) node. The information includes location information relating to the terminal and information as to whether the terminal is de-registered from a 3GPP access network. If the terminal is instead connected via a non-3GPP access network, the method helps avoid terminal location inaccuracies typically associated with non-3GPP access networks.
