Abstract
The disclosure relates to a communication technique and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The disclosure relates to a wireless communication system, and more particularly, to a method and an apparatus for providing a local area data network service based on a non-subscription model in a cellular wireless communication system (5G system).
Claims12
A method by an access and mobility management function (AMF) entity in a wireless communication system, the method comprising:
- receiving, from a terminal, a first message for requesting a protocol data unit (PDU) session establishment including a first local area data network (LADN) data network name (DNN);
- determining whether the first LADN DNN is configured at the AMF entity as a LADN DNN;
- determining whether the terminal is present in a LADN service area, in case that the first LADN DNN is configured at the AMF entity as the LADN DNN;
- and
- transmitting, to a session management function (SMF) entity, a second message indicating whether the terminal is present in the LADN service area.
A method by a session management function (SMF) entity in a wireless communication system, the method comprising:
- receiving, from an access and mobility management function (AMF) entity, a first message including information indicating whether a terminal is present in a local area data network (LADN) service area;
- determining to subscribe to a terminal mobility event report service based on the first message;
- transmitting, to the AMF entity, a second message including an LADN data network name (DNN);
- and
- receiving, from the AMF entity, a third message for a mobility event report of a terminal associated with the LADN DNN,
- wherein the first message is received, in case that a fourth message for requesting a protocol data unit (PDU) session establishment including a first LADN DNN is transmitted from the terminal to the AMF entity and the first LADN DNN is configured at the AMF entity as the LADN DNN.
An access and mobility management function (AMF) entity in a wireless communication system, the AMF entity comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive, from a terminal via the transceiver, a first message for requesting a protocol data unit (PDU) session establishment including a first local area data network (LADN) data network name (DNN),
- determine whether the first LADN DNN is configured at the AMF entity as a LADN DNN,
- determine whether the terminal is present in a LADN service area, in case that the first LADN DNN is configured at the AMF entity as the LADN DNN;
- and
- transmit, to a session management function (SMF) entity via the transceiver, a second message indicating whether the terminal is present in the LADN service area.
A session management function (SMF) entity in a wireless communication system, the SMF entity comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive, from an access and mobility management function (AMF) entity via the transceiver, a first message including information indicating whether a terminal is present in a local area data network (LADN) service area,
- determine to subscribe to a terminal mobility event report service based on the first message,
- transmit, to the AMF entity via the transceiver, a second message including an LADN data network name (DNN), and
- receive, from the AMF entity, a third message for a mobility event report of a terminal associated with the LADN DNN,
- wherein the first message is received, in case that a fourth message for requesting a protocol data unit (PDU) session establishment including a first LADN DNN is transmitted from the terminal to the AMF entity and the first LADN DNN is configured at the AMF entity as the LADN DNN.
