User equipment, server, and methods therefor
An edge enabler client (EEC) ( 2 ) of a User Equipment (UE) ( 1 ) receives from an edge configuration server (ECS) ( 7 ) a service provisioning notification containing edge data network (EDN) configuration information for accessing an EDN ( 4 ), and responds to the ECS ( 7 ) with a response message in response to receiving the service provisioning notification. For example, this can allow the ECS to know whether or not a service provisioning notification has been successfully received by the EEC of the UE in a Subscribe/Notify model based service provisioning procedure.
1 . A User Equipment (UE) comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive, from an edge configuration server, a first service provisioning notification, wherein the first service provisioning notification includes edge data network (EDN) configuration information, and wherein the EDN configuration information includes a list of at least one Edge Enabler Server (EES); and
send, to the edge configuration server, a response message that is configured to cause the edge configuration server to send a second service provisioning notification.
2 . The UE according to claim 1 , wherein the response message indicates information related to failure.
3 . The UE according to claim 2 , wherein
the response message includes information regarding a cause of the failure to receive the EDN configuration information.
4 . The UE according to claim 2 , wherein the response message includes information regarding a cause of the failure to configure or store the EDN configuration information.
5 . A method performed by a User Equipment (UE), the method comprising:
receiving, from an edge configuration server, a first service provisioning notification, wherein the first service provisioning notification includes edge data network (EDN) configuration information, and wherein the EDN configuration information includes a list of at least one Edge Enabler Server (EES); and
sending, to the edge configuration server, a response message that is configured to cause the edge configuration server to send a second in service provisioning notification.
6 . The method according to claim 5 , wherein the EDN configuration information includes at least one of information indicating one or more topological areas associated with the edge configuration server, information indicating a Data Network (DN), or information indicating an Access Point Name (APN).
7 . The method according to claim 5 , wherein the first service provisioning notification is received in a case where an event occurs at the edge configuration server that satisfies trigger conditions for updating service provisioning of the UE.
8 . The method according to claim 5 , wherein the second service provisioning notification includes the EDN configuration information.
9 . An edge configuration server comprising:
a memory; and
at least one processor coupled to the memory and configured to:
send, to a User Equipment (UE), a first service provisioning notification, wherein the first service provisioning notification includes edge data network (EDN) configuration information, and wherein the EDN configuration information includes a list of at least one Edge Enabler Server (EES);
receive a response message sent by the UE; and
based on receiving the response message, send a second service provisioning notification.
10 . The edge configuration server according to claim 9 , wherein the response message indicates information related to failure.
11 . The edge configuration server according to claim 10 , wherein
the response message includes information regarding a cause of the failure by the UE to receive the EDN configuration information.
12 . The edge configuration server according to claim 10 , wherein the response message includes information regarding a cause of the failure by the UE to configure or store the EDN configuration information.
13 . The edge configuration server according to claim 9 , wherein the at least one processor is configured to send a notification to the UE prompting the UE to send a service provisioning unsubscribe request when a number of retransmissions of the service provisioning notification reaches a predetermined value.
14 . The edge configuration server according to claim 9 , wherein the at least one processor is configured to send a notification to the UE prompting the UE to send a service provisioning unsubscribe request if the response message is not received, if the response message indicates a failure to receive, if the response message indicates a failure to configure, or if the response message indicates a failure to store.
