The method includes performing a mutual authentication procedure with a terminal, generating an event checking identifier (ECID) associated with an embedded universal integrated circuit card (eUICC) identifier (EID), and transmitting, to the terminal, a message including the ECID, wherein the ECID is stored in the terminal and associated with an address of the SM-DS server. ## Claims ### Claim 1 A method performed by a subscription manager discovery service (SM-DS) server in a wireless communication system, the method comprising: performing a mutual authentication procedure with a terminal, wherein the performing of the mutual authentication procedure comprises receiving, from the terminal, device information including information indicating that the terminal supports an event checking; generating an event checking identifier (ECID) associated with an embedded universal integrated circuit card (eUICC) identifier (EID) in case that the SM-DS server supports the event checking, based on the performing of the mutual authentication procedure, wherein the ECID is an identifier (ID) for determining a presence of event records registered for an eUICC; and transmitting, to the terminal, a message including the ECID, wherein the ECID is stored in the terminal and associated with an address of the SM-DS server. ### Claim 2 (depends on 1) The method of claim 1, further comprising: receiving, from the terminal, a request message for an-the event-check checking, the request message including the ECID corresponding to the SM-DS server; and verifying whether the ECID is valid. ### Claim 3 (depends on 2) The method of claim 2, further comprising: checking whether there is an event associated with the ECID; and transmitting, to the terminal, information on whether there is the event associated with the ECID. ### Claim 4 (depends on 2) The method of claim 2, further comprising: transmitting, to the terminal, an error message indicating that the ECID is not valid, in case that the verification fails. ### Claim 5 (depends on 2) The method of claim 2, further comprising: transmitting, to the terminal, an error message in case that the SM-DS server does not support the event checking. ### Claim 6 A method performed by a terminal in a wireless communication system, the method comprising: performing a mutual authentication procedure with a subscription manager discovery service (SM-DS) server, wherein the performing of the mutual authentication procedure comprises transmitting, to the SM-DS server, device information including information indicating that the terminal supports an event checking; receiving, from the SM-DS server, a message including an event checking identifier (ECID) associated with an embedded universal integrated circuit card (eUICC) identifier (EID), wherein the ECID is an identifier (ID) for determining a presence of event records registered for an eUICC; and storing the ECID associated with an address of the SM-DS server. ### Claim 7 (depends on 6) The method of claim 6, further comprising: transmitting, to the SM-DS server, a request message for the event checking, the request message including the ECID corresponding to the SM-DS server, wherein whether the ECID is valid is verified based on the request message. ### Claim 8 (depends on 7) The method of claim 7, further comprising: receiving, from the SM-DS server, information on whether there is an event associated with the ECID. ### Claim 9 (depends on 7) The method of claim 7, further comprising: receiving, from the SM-DS server, an error message indicating that the ECID is not valid, in case that the verification fails. ### Claim 10 (depends on 7) The method of claim 7, further comprising: receiving, from the SM-DS server, an error message in case that the SM-DS server does not support the event checking. ### Claim 11 A subscription manager discovery service (SM- DS) server in a wireless communication system, the SM-DS server comprising: a transceiver; and at least one processor coupled with the transceiver and configured to: perform a mutual authentication procedure with a terminal, wherein, for performing the mutual authentication procedure, the at least one processor is configured to receive, from the terminal, device information including information indicating that the terminal supports an event checking, generate an event checking identifier (ECID) associated with an embedded universal integrated circuit card (eUICC) identifier (EID) in case that the SM-DS server supports the event checking. based on the performing of the mutual authentication procedure, wherein the ECID is an identifier (ID) for determining a presence of event records registered for an eUICC, and transmit, to the terminal, a message including the ECID, wherein the ECID is stored in the terminal and associated with an address of the SM-DS server. ### Claim 12 (depends on 11) The SM-DS server of claim 11, wherein the at least one processor is further configured to: receive, from the terminal, a request message for the event checking, the request message including the ECID corresponding to the SM-DS server, and verify whether the ECID is valid. ### Claim 13 (depends on 12) The SM-DS server of claim 12, wherein the at least one processor is further configured to: transmit, to the terminal, an error message indicating that the ECID is not valid, in case that the verification fails; and transmit, to the terminal, information on whether there is an event associated with the ECID, in case that the ECID is valid. ### Claim 14 A terminal in a wireless communication system, 14. the terminal comprising: a transceiver; and at least one processor coupled with the transceiver and configured to: perform a mutual authentication procedure with a subscription manager discovery service (SM-DS) server, wherein, for performing the mutual authentication procedure with the SM-DS server, the at least one processor is configured to transmit, to the SM-DS server, device information including information indicating that the terminal supports an event checking, receive, from the SM-DS server, a message including an event checking identifier (ECID) associated with an embedded universal integrated circuit card (eUICC) identifier (EID), wherein the ECID is an identifier (ID) for determining a presence of event records registered for an eUICC, and store the ECID associated with an address of the SM-DS server. ### Claim 15 (depends on 14) The terminal of claim 14, wherein the at least one processor is further configured to transmit, to the SM-DS server, a request message for the check checking, the request message including the ECID corresponding to the SM-DS server, and wherein whether the ECID is valid is verified based on the request message.
