METHOD AND APPARATUS FOR DETERMINING PDU SESSION IDENTITY IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for determining, by a session management function (SMF) node, a packet data network (PDU) session identity during handover of user equipment (UE) in a wireless communication system, the method comprising:
- receiving a request message for requesting an establishment of a PDU session for the UE from an access and mobility management function (AMF) node,wherein a handover for the UE from a first wireless communication system to a second wireless communication system has been determined;
determining a PDU session identity for the PDU session established for the UE when the request message is received; and
sending a response message including the determined PDU session identity to the AMF node in response to the request message.

Abstract
Disclosed are a method and apparatus for determining a PDU session identity in a wireless communication system. A method for determining, by a session management function (SMF) node, a packet data network (PDU) session identity during handover of user equipment (UE) in a wireless communication system, may include receiving a request message for requesting the establishment of a PDU session for the UE from an access and mobility management function (AMF) node, wherein a handover for the UE from a first wireless communication system to a second wireless communication system has been determined, determining a PDU session identity for the PDU session established for the UE when the request message is received, and sending a response message including the determined PDU session identity to the AMF node in response to the request message.

12. A session management function (SMF) node for determining a packet data network (PDU) session identity during handover of user equipment (UE) in a wireless communication system, the SMF node comprising:
-
a communication module configured to send or receive a signal; and a processor configured to control the communication module, wherein the processor is configured to; receive a request message for requesting an establishment of a PDU session for the UE from an access and mobility management function (AMF) node, wherein a handover for the UE from a first wireless communication system to a second wireless communication system has been determined, determine a PDU session identity for the PDU session established for the UE when the request message is received, and send a response message including the determined PDU session identity to the AMF node in response to the request message.
