Method and device for supporting edge application server in wireless communication system supporting edge computing
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate, and relates to a method and device for efficiently supporting an EAS in a wireless communication system supporting edge computing. A method performed by an EES is provided, which includes receiving, from an EAS not configured in the EES, a registration request message including network slice information related to the EAS, selecting a UE to which EAS information about the EAS is to be provided and a method for providing the EAS information, and providing the EAS information to the UE based on the selected method.
1 . A method performed by an edge enabler server (EES) providing supporting functions for an edge application server (EAS) and an edge enabler client (EEC) of a user equipment (UE) in a wireless communication system supporting edge computing, the method comprising:
receiving, from at least one of the EAS or the EEC, a registration request message including at least one of network slice information related to the EAS, EAS type information, or application client (AC) type information related to supporting a network slice or a data network name (DNN) of the EAS;
performing a configuration of the EAS with EAS information associated with the network slice information;
identifying the UE to which EAS information about the EAS is to be provided; and
providing the EAS information to the UE.
2 . The method of claim 1 , wherein selecting a UE comprises selecting the UE to which the EAS information is to be provided based on at least one of filter information received from the UE, an edge computing service provider (ECSP) policy, area information set in the EES, or a subscriber list.
3 . The method of claim 1 , further comprising identifying a method for providing the EAS information to the UE,
wherein the method for providing the EAS information comprises providing the EAS to the UE directly by the EES, using one of an EAS discovery response or an EAS discovery notification.
4 . The method of claim 1 , wherein providing the EAS information to the UE comprises transmitting a request message according to a UE route selection policy (URSP) guidance to a network exposure function (NEF) of a core network in case that the EES receives information related to a URSP guidance request from the EAS.
5 . An edge enabler server (EES) providing supporting functions for an edge application server (EAS) and an edge enabler client (EEC) of a user equipment (UE) in a wireless communication system supporting edge computing, the EES comprising:
a transceiver; and
a processor configured to:
receive, via the transceiver, from at least one of the EAS or the EEC, a registration request message including at least one of network slice information related to the EAS, EAS type information, or application client (AC) type information related to supporting a network slice or a data network name (DNN) of the EAS,
perform a configuration of the EAS with EAS information associated with the network slice information;
identify the UE to which EAS information about the EAS is to be provided, and
provide the EAS information to the UE.
6 . The EES of claim 5 , wherein the processor is further configured to select the UE to which the EAS information is to be provided based on at least one of filter information received from the UE, an edge computing service provider (ECSP) policy, area information set in the EES, or a subscriber list.
7 . The EES of claim 5 , wherein the processor is further configured to identify a method for providing the EAS information to the UE, and
wherein the method for providing the EAS information comprises providing the EAS information to the UE directly by the EES, using one of an EAS discovery response or an EAS discovery notification.
8 . The EES of claim 5 , wherein the processor is further configured to transmit a request message according to a UE route selection policy (URSP) guidance to a network exposure function (NEF) of a core network through the transceiver in case that the EES receives information related to a URSP guidance request from the EAS.
9 . A method performed by a user equipment (UE) in a wireless communication system supporting edge computing, the method comprising:
transmitting, to an edge enabler server (EES), a request message including filter information related to an edge application server (EAS) to which a specific network slice not previously configured in the EES is applied, the filter information including at least one of EAS type information or application client (AC) type information related to support the specific network slice, the EES providing supporting functions for the EAS and an edge enabler client (EEC) of the UE; and
receiving a response message including at least one of network slice information related to the EAS or a data network name (DNN) from the EES based on the filter information.
10 . A user equipment (UE) in a wireless communication system supporting edge computing, the UE comprising:
a transceiver; and
a processor configured to:
transmit, via the transceiver, to an edge enabler server (EES), a request message including filter information related to an edge application server (EAS) to which a specific network slice not previously configured in the EES is applied, the filter information including at least one of EAS type information or application client (AC) type information related to support the specific network slice, the EES providing supporting functions for the EAS and an edge enabler client (EEC) of the UE, and
receive, via the transceiver, a response message including at least one of network slice information related to the EAS or a data network name (DNN) from the EES based on the filter information.
