Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, the present invention comprises the steps of: an access and mobility management function (AMF) of a 5G core network determining whether a terminal has moved to an area in which packet transmission/reception is possible, or an area in which packet transmission/reception is impossible; transmitting a message including information on the determination result to a session management function (SMF); and transmitting a response message including information associated with a change in the state of a session to the terminal. In addition, the present invention relates to a method and a device for blocking or allowing the transmission/reception of a packet transmission session (PDU session) according to the position of a terminal in a 5G system. In a 5G system, a local area data network service by which a packet session is valid only in a specific area will be supported, and a method is required for allowing the transmission of a packet of a session only in an area that can be divided into a cell or a tracking area. Additionally, in a 5G system, an allowed area in which the transmission/reception of a packet of a session according to each position of a terminal is allowed, and a non-allowed area in which same is not allowed are present, and thus packet transmission may be allowed or not according to area. In order to provide such service, the present invention provides a procedure whereby the state of a session is defined in a packet transmission non-allowed area, and a change in the state of the session occurs when moving from a packet transmission-allowed area to the non-allowed area.
