Abstract
The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) system, such as long-term evolution (LTE). The disclosure provides a method for operating a terminal in a wireless communication system, the method including: performing communication with an access and mobility management function (AMF) in a first network; and transmitting a radio resource control (RRC) message including information on the AMF in a second network.
Claims9
A method for operating a network node in a wireless communication system, the method comprising:
- receiving, from a user equipment (UE) supporting a first radio access technology (RAT) and a second RAT, a UE-initiated deregistration request message;
- determining whether a usage reporting for the second RAT is required for a protocol data unit (PDU) session established for the UE;
- in case that the usage reporting for the second RAT is required for the PDU session, transmitting, to the UE, a deregistration accept message, and transmitting, to a radio access node (RAN) associated with the UE, a N2 UE context release request message for a signaling connection release of the RAN;
- waiting for completion of the signaling connection release of the RAN, to receive the usage reporting for the second RAT from the RAN;
- and
- transmitting, to a session management function (SMF), a PDU session release request message to release the PDU session.
A network node in a wireless communication system, the network node comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive, from a user equipment (UE) supporting a first radio access technology (RAT) and a second RAT, a UE-initiated deregistration request message;
- determine whether a usage reporting for the second RAT is required for a protocol data unit (PDU) session established for the UES;
- in case that the usage reporting for the second RAT is required for the PDU session, transmit, to the UE, a deregistration accept message, and transmit, to a radio access node (RAN) associated with the UE, a N2 UE context release request message for a signaling connection release of the RAN;
- wait for completion of the signaling connection release of the RAN, to receive the usage reporting for the second RAT from the RAN;
- and
- transmit, to a session management function (SMF), a PDU session release request message to release the PDU session.
