Method and apparatus for service using tethering in wireless communication system
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment of the disclosure, a policy control function (PCF) entity in a wireless communication system comprises a transceiver and at least one processor. The at least one processor is configured to update a service-related policy based on a service transmission delay time (delay budget adjustment) per service flow, wherein the service transmission delay time per service flow is transmitted to a tethered device, schedule a quality-of-service (QoS) based on the service-related policy, and transmit, to a session management function (SMF) entity, a first message including the per-service flow service transmission delay time per service flow, the updated service-related policy, and a QoS requirement based on the scheduled QoS.
1 . A session management function (SMF) entity in a wireless communication system, the SMF entity comprising:
a transceiver; and
at least one processor, wherein the at least one processor is configured to:
receive, from a user equipment (UE) via an access and mobility management function (AMF) entity, a request for a packet data unit PDU) session including delay information indicating a delay between the UE and a non-3GPP (non-3rd generation partnership project) device, wherein the UE and the non-3GPP device communicate with each other; and
transmit, to a radio access network (RAN) via the AMF entity, information on a quality of service (QoS) flow and information on a delay budget adjustment associated with the QoS flow, wherein the delay budget adjustment is related to the delay information received from the UE.
2 . The SMF entity of claim 1 , wherein the delay budget adjustment is related to a group identifier (ID) per service flow of a group including at least one non-3GPP device.
3 . The SMF entity of claim 1 , wherein the at least one processor is configured to include the information on the delay budget adjustment in time sensitive communication assistance information (TSCAI) and transmit, to the RAN, the TSCAI.
4 . The SMF entity of claim 1 , wherein the delay budget adjustment is related to at least one of information for distinguishing at least one service flow transmitted to the non-3GPP device and connection information for the non-3GPP device.
5 . A method performed by a session management function (SMF) in a wireless communication system, the method comprising:
receiving, from user equipment (UE) via an access and mobility management function (AMF), a request for a packet data unit (PDU) session including delay information indicating a delay between the UE and a non-3GPP (non-3rd generation partnership project) device, wherein the UE and the non-3GPP device communicate with each other; and
transmitting, to a radio access network (RAN) via the AMF entity, information on a quality of service (QoS) flow and information on a delay budget adjustment associated with the QoS flow, wherein the delay budget adjustment is related to the delay information received from the UE.
6 . The method of claim 5 , wherein the delay budget adjustment is related to a group identifier (ID) per service flow of a group including at least one non-3GPP device.
7 . The method of claim 5 , further comprising including the information on the delay budget adjustment in time sensitive communication assistance information (TSCAI) and transmitting, to the RAN, the TSCAI.
8 . The method of claim 5 , wherein the delay budget adjustment is related to at least one of information for distinguishing at least one service flow transmitted to the non-3GPP device and connection information for the non-3GPP device.
9 . The method of claim 5 , wherein the delay information is related to a data network name (DNN) and a single network slice selection assistance information (S-NSSAI) of the PDU session.
10 . The SMF entity of claim 1 , wherein the delay information is related to a data network name (DNN) and a single network slice selection assistance information (S-NSSAI) of the PDU session.
