Abstract

Claims (73)

1. A method for providing continuity for a service by a user equipment (UE) in a wireless communication network system, the method comprising:

connecting, by an application client (AC) in the UE, to a first edge application server (EAS);

receiving, by the AC in the UE from the first EAS, data packets related to the service;

identifying a second EAS that provides the service at a location of the UE, wherein the second EAS is different from the first EAS;

transmitting, by an edge enabler client (EEC) in the UE to a first edge enabler server (EES) associated with the first EAS, information regarding a connection with a second EES associated with the second EAS;

initiating, by the AC in the UE, a transfer of application context of the service from the first EAS to the second EAS; and

connecting the service from the second EAS and disconnecting the service from the first EAS,

wherein the first EES and the first EAS are included in a first edge data network (EDN), and

wherein the second EES and the second EAS are included in a second EDN.

2. The method of claim 1 , further comprising:

transmitting, to an edge configuration server (ECS), information that the UE locates in a service area in response to service availability information;

receiving, from the ECS, operational rules of the service area in response to the information that the UE locates in the service area; and

executing the received operational rules.

3. A method for providing continuity for a service by a first edge application server (EAS) in a wireless communication network system, the method comprising:

connecting with an application client (AC) in a user equipment (UE);

transmitting, to the UE, data packets related to the service;

receiving, from the UE, information related to the connection of the UE with a second EAS, wherein a transfer of application context of the service from the first EAS to the second EAS is initiated by the AC in the UE;

transmitting, to the UE, information including a notification that indicates the transfer of the application context of the service to the second EAS is completed;

transmitting, to the UE, end data packets related to the service in response to receiving a notification about establishment of the connection of the UE with the second EAS; and

disconnecting a connection of the UE,

wherein the first EAS and a first edge enabler server (EES) associated with the first EAS are included in a first edge data network (EDN), and

wherein the second EAS and a second EES associated with the second EAS are included in a second EDN.

4. The method of claim 3 , further comprising:

receiving, from the UE, a request for capturing the application context of the service and transferring the captured application context of the service to the second EAS;

in response to receiving the request, capturing the application context of the service and transmitting, to the second EAS, the captured application context of the service to the second EAS; and

in response to transmitting the captured application context of the service to the second EAS, receiving, from the second EAS, a response indicating an acknowledgement of the captured application context of the service.

5. A method for providing continuity for a service by a second edge application server (EAS) in a wireless communication network system, the method comprising:

receiving, from a user equipment (UE), a connection request;

transmitting, to the UE, a connection response indicating that the connection request is accepted;

after a connection of the UE with a first EAS is switched to a connection of the UE with the second EAS, transmitting, to the first EAS, information related to the connection of the UE with the second EAS; and

transmitting, to the UE, data packets related to the service after transmitting the information related to the connection of the UE with the second EAS,

wherein a transfer of application context of the service from the first EAS to the second EAS is initiated by an application client in the UE,

wherein the first EAS and a first edge enabler server (EES) associated with the first EAS are included in a first edge data network (EDN), and

wherein the second EAS and a second EES associated with the second EAS are included in a second EDN.

6. The method of claim 5 , further comprising:

receiving, from the first EAS, the application context of the service; and

transmitting, to the first EAS, a response indicating an acknowledgement of the application context of the service.

7. A user equipment (UE) for providing a continuity for a service in a wireless communication network system, the UE comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to control to:

connect, by an application client (AC) in the UE, to a first edge application server (EAS),

receive, by the AC in the UE from the first EAS, data packets related to the service,

identify a second EAS that provides the service at a location of the UE, wherein the second EAS is different from the first EAS,

transmit, by an edge enabler client (EEC) in the UE to a first edge enabler server (EES) associated with the first EAS, information regarding a connection with a second EES associated with the second EAS,

initiate, by the AC in the UE, a transfer of application context of the service from the first EAS to the second EAS, and

connect the service from the second EAS and disconnect the service from the first EAS,

wherein the first EES and the first EAS are included in a first edge data network EDN), and

wherein the second EES and the second EAS are included in a second EDN.

8. The UE of claim 7 , wherein the at least one processor is configured to control to:

transmit, to an edge configuration server (ECS), information that the UE locates in a service area in response to service availability information,

receive, from the ECS, operational rules of the service area in response to the information that the UE locates in the service area, and

execute the received operational rules.

9. A first edge application server (EAS) for providing a continuity for a service in a wireless communication network system, the first EAS comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to control to:

connect with an application client (AC) in a user equipment (UE),

transmit, to the UE, data packets related to the service,

receive, from the UE, information related to the connection of the UE with a second EAS, wherein a transfer of application context of the service from the first EAS to the second EAS is initiated by the AC in the UE,

transmit, to the UE, information including a notification that indicates the transfer of the application context of the service to the second EAS is completed,

transmit, to the UE, end data packets related to the service in response to receiving a notification about establishment of the connection of the UE with the second EAS, and

disconnect a connection of the UE,

wherein the first EAS and a first edge enabler server (EES) associated with the first EAS are included in a first edge data network (EDN), and

wherein the second EAS and a second EES associated with the second EAS are included in a second EDN.

10. A second edge application server (EAS) for providing a continuity for a service in a wireless communication network system, the second EAS comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to control to:

receive, from a user equipment (UE), a connection request,

transmit, to the UE, a connection response indicating that the connection request is accepted,

after a connection of the UE with a first EAS is switched to a connection of the UE with the second EAS, transmit, to the first EAS, information related to the connection of the UE with the second EAS, and

transmit, to the UE, data packets related to the service after transmitting the information related to the connection of the UE with the second EAS,

wherein a transfer of application context of the service from the first EAS to the second EAS is initiated by an application client in the UE,

wherein the first EAS and a first edge enabler server (EES) associated with the first EAS are included in a first edge data network (EDN), and

wherein the second EAS and a second EES associated with the second EAS are included in a second EDN.
