Content provision method and apparatus using convergence network
Disclosed herein are a content provision method and apparatus using a convergence network. The content provision method may include creating a Quick UDP Internet Connections V1 (QUICV1) path with User Equipment (UE) through a Fifth-Generation (5G) core, when content satisfies a preset condition while the content is being provided to the UE through the QUICV1 path, determining to offload the content through the 5G core, creating an Internet Protocol Security (IPSEC) tunnel with an Advanced Television Systems Committee (ATSC) gateway (GW) through the 5G core, generating a QUIC multicast stream, providing QUIC multicast session information to multiple UE devices, and providing the content to multiple UE devices, for which a mode switches from a QUICV1 mode to a QUIC multicast mode, through the ATSC GW.
1. A content provision method using a convergence network, comprising:
creating a Quick UDP Internet Connections V1 (QUICV1) path with User Equipment (UE) through a Fifth-Generation (5G) core;
when content satisfies a preset condition while the content is being provided to the UE through the QUICV1 path, determining to offload the content through the 5G core;
creating an Internet Protocol Security (IPSEC) tunnel with an Advanced Television Systems Committee (ATSC) gateway (GW) through the 5G core;
generating a QUIC multicast stream;
providing QUIC multicast session information to multiple UE devices; and
providing the content to multiple UE devices, for which a mode switches from a QUICV1 mode to a QUIC multicast mode, through the ATSC GW.
2. The content provision method of claim 1 , wherein the preset condition is established based on popularity of the content.
3. The content provision method of claim 2 , wherein the preset condition is established based on a condition, in which the popularity of the content is equal to or greater than a reference value, and a geographic closeness condition.
4. The content provision method of claim 1 , wherein the IPSEC tunnel with the ATSC GW is created through an N3 Interworking Function (N3IWF) of the 5G core.
5. The content provision method of claim 1 , further comprising:
when the preset condition is not satisfied, reactivating the QUICV1 mode and deactivating the QUIC multicast mode.
6. The content provision method of claim 1 , further comprising:
when a response to failure in delivery of the content to the UE is received, requesting a QUIC packet range from the 5G core, and receiving the QUIC packet range from the 5G core.
7. The content provision method of claim 6 , further comprising:
when the QUIC packet range is received from the 5G core, activating the QUICV1 mode, and
providing the content to the UE through the QUICV1 path.
8. The content provision method of claim 1 , wherein the convergence network is configured using the 5G core and the ATSC GW.
9. The content provision method of claim 1 , wherein:
the ATSC GW comprises a 5G Application Function (AF) and an IPSEC client, and
the 5G AF performs a request to create, modify or discard a convergent service by attaching to the 5G core using a standardized 5G Application Programming Interface (API).
10. The content provision method of claim 9 , wherein the IPSEC client is used to attach the ATSC GW to the 5G core.
11. A content provision apparatus using a convergence network, comprising:
a memory configured to store a control program for content provision; and
a processor configured to execute the control program stored in the memory,
wherein the processor is configured to create a Quick UDP Internet Connections V1 (QUICV1) path with User Equipment (UE) through a Fifth-Generation (5G) core, when content satisfies a preset condition while the content is being provided to the UE through the QUICV1 path, determine to offload the content through the 5G core, create an Internet Protocol Security (IPSEC) tunnel with an Advanced Television Systems Committee (ATSC) gateway (GW) through the 5G core, generate a QUIC multicast stream, provide QUIC multicast session information to multiple UE devices, and provide the content to multiple UE devices, for which a mode switches from a QUICV1 mode to a QUIC multicast mode, through the ATSC GW.
12. The content provision apparatus of claim 11 , wherein the preset condition is established based on popularity of the content.
13. The content provision apparatus of claim 12 , wherein the preset condition is established based on a condition, in which the popularity of the content is equal to or greater than a reference value, and a geographic closeness condition.
14. The content provision apparatus of claim 11 , wherein the processor is configured to create the IPSEC tunnel with the ATSC GW through an N3 Interworking Function (N3IWF) of the 5G core.
15. The content provision apparatus of claim 11 , wherein the processor is configured to, when the preset condition is not satisfied, reactivate the QUICV1 mode and deactivate the QUIC multicast mode.
16. The content provision apparatus of claim 11 , wherein the processor is configured to, when a response to failure in delivery of the content to the UE is received, request a QUIC packet range from the 5G core, and receive the QUIC packet range from the 5G core.
17. The content provision apparatus of claim 16 , wherein the processor is configured to:
when the QUIC packet range is received from the 5G core, activate the QUICV1 mode, and
provide the content to the UE through the QUICV1 path.
18. The content provision apparatus of claim 11 , wherein the convergence network is configured using the 5G core and the ATSC GW.
19. The content provision apparatus of claim 11 , wherein:
the ATSC GW comprises a 5G Application Function (AF) and an IPSEC client, and
the 5G AF performs a request to create, modify or discard a convergent service by attaching to the 5G core using a standardized 5G Application Programming Interface (API).
20. The content provision apparatus of claim 19 , wherein the IPSEC client is used to attach the ATSC GW to the 5G core.
