The method includes: receiving, from a first node, a first message for deleting an event subscription for at least one user equipment, UE; determining whether the at least one UE is an individual UE or a group member UE; sending a second message to a second node, when the at least one UE is a group member UE, wherein the second message includes UE identification information of the at least one UE. ## Claims ### Claim 1 A method implemented at a network exposure node, the method comprising: receiving, from a first node, a first message for deleting an event subscription for at least one user equipment, UE; determining from the first message whether the at least one UE is an individual UE or a group member UE; and sending a second message to a second node, wherein if the at least one UE is determined to be a group member UE, the second message includes UE identification information of the at least one UE and an event related subscription is not deleted; and if the at least one UE is determined to be an individual UE, the method further comprises deleting the event related subscription. ### Claim 2 (depends on 1) The method according to claim 1, wherein the UE identification information comprises External Identifier, and/or Mobile Subscriber International Integrated Services Digital Network number, MSISDN of the UE. ### Claim 3 (depends on 1) The method according to claim 1, wherein the second message further includes an event subscription identifier which identifies a specific event subscription and a cancellation indication which indicates to cancel a configured event subscription for the at least one UE. ### Claim 4 (depends on 1) The method according to claim 1, the method further comprises: when the cancellation indication of all the UEs in a group have been received, delete the event subscription related resource. ### Claim 5 (depends on 1) The method according to claim 1, wherein the determining whether the at least one UE is an individual UE or a group member UE is based on the first message, wherein the first message includes an indicator which indicates whether the UE is a group member UE. ### Claim 6 (depends on 5) The method according to claim 5, wherein the indicator is External Group Identifier of the UE, and if the first message includes the External Group Identifier, the network exposure node determines the UE is a group member UE, or else the network exposure node determines the UE is an individual UE. ### Claim 7 (depends on 1) The method according to claim 1, wherein the network exposure node is Service Capability Exposure Function, SCEF, or Network Exposure Function, NEF. ### Claim 8 (depends on 1) The method according to claim 1, wherein the first node is Home Subscriber Server, HSS, or Home Location Register, HLR. ### Claim 9 (depends on 1) The method according to claim 1, wherein the second node is Service Capability Server, SCS or Application Server, AS, or a destination node whose Uniform Resource Locator, URL, is provided by the SCS/AS before. ### Claim 10 (depends on 1) The method according to claim 1, wherein the first message is Monitoring Indication message or Set Suggested Network Configuration Response message. ### Claim 11 (depends on 1) The method according to claim 1, wherein the second message is a Hyper-Text Transfer Protocol POST message or Cancel Monitoring Event Request message. ### Claim 12 A network exposure node, comprising: at least one processor; and at least one memory, the at least one memory containing instructions executable by the at least one processor, whereby the at least one processor is operative to: receive, from a first node, a first message for deleting an event subscription for at least one user equipment, UE; determine from the first message whether the at least one UE is an individual UE or a group member UE; and send a second message to a second node, wherein if the at least one UE is determined to be a group member UE, the second message includes UE identification information of the at least one UE and an event related subscription is not deleted; and if the at least one UE is determined to be an individual UE, the processor is further operative to delete the event related subscription. ### Claim 13 (depends on 12) The network exposure node according to claim 12, wherein the UE identification information comprises External Identifier, and/or Mobile Subscriber International Integrated Services Digital Network number, MSISDN of the UE. ### Claim 14 (depends on 12) The network exposure node according to claim 12, wherein the second message further includes an event subscription identifier which identifies a specific event subscription and a cancellation indication which indicates to cancel a configured event subscription for the at least one UE. ### Claim 15 (depends on 12) The network exposure node according to claim 12, wherein the at least one processor is further operative to, when the cancellation indication of all the UEs in a group have been received, delete the event subscription related resource. ### Claim 16 (depends on 12) The network exposure node according to claim 12, wherein to determine whether the at least one UE is an individual UE or a group member UE is based on the first message, wherein the first message includes an indicator which indicates whether the UE is a group member UE. ### Claim 17 (depends on 16) The network exposure node according to claim 16, wherein the indicator is an External Group Identifier of the UE, and if the first message includes the External Group Identifier, the at least one processor network exposure node determines the UE is a group member UE, or else the at least one processor determines the UE is an individual UE. ### Claim 18 A non-transitory computer readable storage medium comprising instructions which when executed by at least one processor, cause the at least one processor to: receive, from a first node, a first message for deleting an event subscription for at least one user equipment, UE; determine from the first message whether the at least one UE is an individual UE or a group member UE; and send a second message to a second node, wherein if the at least one UE is determined to be a group member UE, the second message includes UE identification information of the at least one UE and an event related subscription is not deleted; and if the at least one UE is determined to be an individual UE, the processor deletes the event related subscription.
