Device and method for supporting TSC in wireless communication network
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. The present invention relates to a method for an application function (AF) entity for time sensitive communication (TSC) in a wireless communication system, the method comprising the steps of: obtaining first delay-related information on a time sensitive network (TSN); obtaining second delay-related information on a 5 th generation system (5GS); and transmitting, to a policy control function (PCF) entity, a quality of service (QoS)-related request based on the first delay-related information and the second delay-related information.
1. A method of an application function (AF) entity for a time sensitive communication (TSC) in a wireless communication system, the method comprising:
obtaining first delay information for a time sensitive network (TSN);
obtaining second delay information for a 5th generation system (5GS); and
transmitting, to a policy control function (PCF) entity, a request for a quality-of-service (QoS) based on the first delay information and the second delay information, wherein a first delay requirement associated with the first delay information is converted to second delay requirement associated with the second delay information based on a difference in a delay time.
2. The method of claim 1 , wherein the request includes a set of requirements for the difference in the delay time associated with the first delay information and the second delay information.
3. The method of claim 1 , further comprising updating a QoS policy based on the request.
4. A method of a policy control function (PCF) entity for a time sensitive communication (TSC) in a wireless communication system, the method comprising:
obtaining first delay information for a 5th generation system (5GS);
transmitting the first delay information to an application function (AF) entity;
obtaining, from the AF entity, a request for a quality-of-service (QOS) based on the first delay information and second delay information, wherein the second delay information is associated with a time sensitive network (TSN) and a first delay requirement associated with the first delay information is converted to second delay requirement associated with the second delay information based on a difference in a delay time; and
determining a QoS policy based on the request.
5. The method of claim 4 , wherein the request includes a set of requirements for the difference in the delay time associated with the first delay information and the second delay information.
6. The method of claim 4 , further comprising updating the determined QoS policy for a session management function (SMF) entity.
7. An application function (AF) entity for a time sensitive communication (TSC) in a wireless communication system, comprising:
a transceiver; and
at least one controller operably coupled to the transceiver, the at least one controller configured to:
obtain first delay information for a time sensitive network (TSN),
obtain second delay information for a 5th generation system (5GS), and
transmit, to a policy control function (PCF) entity, a request for a quality-of-service (QoS) based on the first delay information and the second delay information, wherein a first delay requirement associated with the first delay information is converted to second delay requirement associated with the second delay information based on a difference in a delay time.
8. The AF entity of claim 7 , wherein the request includes a set of requirements for the difference in the delay time associated with the first delay information and the second delay information.
9. The AF entity of claim 7 , wherein the at least one controller is further configured to update a QoS policy based on the request.
10. A policy control function (PCF) entity for a time sensitive communication (TSC) in a wireless communication system, comprising:
a transceiver; and
at least one controller operably coupled to the transceiver, the at least one controller configured to:
obtain first delay information for a 5th generation system (5GS),
transmit the first delay information to an application function (AF) entity,
obtain, from the AF entity, a request for a quality-of-service (QOS) based on the first delay information and second delay information, wherein the second delay information is associated with a time sensitive network (TSN) and a first delay requirement associated with the first delay information is converted to second delay requirement associated with the second delay information based on a difference in a delay time, and
determine a QoS policy based on the request.
11. The PCF entity of claim 10 , wherein the request includes a set of requirements for the difference in the delay time associated with the first delay information and the second delay information.
12. The PCF entity of claim 10 , wherein the at least one controller is further configured to update the determined QoS policy for a session management function (SMF) entity.
