Abstract
There is provided a method of performing user data communication between a UE and a network via data transmission on the Control Plane, CP, comprising the steps of: the UE determines if it is inside or outside a LADN service area; if it is inside the LADN service area, the UE is permitted to transmit user data over a Non Access Stratum for an LADN PDU session; and if it is outside the LADN service area, the UE is not permitted to transmit user data over a Non Access Stratum for an LADN PDU session; wherein the user data is cellular internet of things (CIoT) user data.
Claims15
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving, from an access and mobility management function (AMF), information on a local area data network (LADN);
- based on the information, identifying whether the terminal is in a LADN service area or out of the LADN service area;
- and
- in case that the terminal is in the LADN service area, transmitting, to the AMF, user data via a control plane for a protocol data unit (PDU) session for the LADN;
- wherein in case that the terminal is out of the LADN service area, the terminal is not allowed to transmit, to the AMF, the user data via the control plane for the PDU session for the LADN.
A method performed by an access and mobility management function (AMF) in a wireless communication system, the method comprising:
- transmitting, to a terminal, information on a local area data network (LADN);
- in case that the terminal is in a LADN service area, receiving, from the terminal, user data via a control plane for a protocol data unit (PDU) session for the LADN;
- wherein in case that the terminal is out of the LADN service area, the terminal is not allowed to transmit, to the AMF, the user data via the control plane for the PDU session for the LADN.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- receive, from an access and mobility management function (AMF), information on a local area data network (LADN),
- based on the information, identify whether the terminal is in a LADN service area or out of the LADN service area, and
- in case that the terminal is in the LADN service area, transmit, to the AMF, user data via a control plane for a protocol data unit (PDU) session for the LADN,
- wherein in case that the terminal is out of the LADN service area, the terminal is not allowed to transmit, to the AMF, the user data via the control plane for the PDU session for the LADN.
An access and mobility management function (AMF) in a wireless communication system, the AMF comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- transmit, to a terminal, information on a local area data network (LADN), and
- in case that the terminal is in a LADN service area, receive, from the terminal, user data via a control plane for a protocol data unit (PDU) session for the LADN,
- wherein in case that the terminal is out of the LADN service area, the terminal is not allowed to transmit, to the AMF, the user data via the control plane for the PDU session for the LADN.
