Abstract

Support of end-to-end edge application service continuity is described herein. In one aspect, a service resident on a first wireless transmit/receive unit (WTRU) can receive, from a first application resident on the first WTRU, information for an association between the first application and a second application resident on a second WTRU. The service can send the association information to a service in the network such that the first and second applications are assigned to a first application server providing the type of service required for first and second application interactions. The service can detect the first WTRU's location is no longer in the service area of the first application server, and can send a request to the service in the network such that the first application and second applications are assigned to a second application server providing the type of service required for interactions between the first and second applications.

First claim

We claim:

1 . A method performed by a service resident on a first wireless transmit/receive unit (WTRU), the method comprising:
receiving, from a first application resident on the first WTRU, information for an association between the first application and a second application resident on a second WTRU, wherein the association information comprises identifiers of the first application and the second application and a type of application service required by the first application and the second application to interact with each other; sending the association information to a service in a network such that the first and the second applications are assigned by the service in the network to a first application server providing the type of service required by the first application and the second application to interact with each other; detecting the first WTRU's location is no longer in a service area of the first application server; and sending a request to the service in the network such that the first application and the second application are assigned by the service in the network to a second application server providing the type of service required by the first application and the second application to interact with each other.

2 . The method of claim 1 , wherein the association information further comprises association service key performance indicators (KPIs) that further comprise one or more of: an aggregated connection bandwidth to the application service required by the first and second applications, or an aggregated rate of requests to the application service required by the first and second applications.

3 . The method of claim 1 , wherein the association information further comprises a service area for which the association between the first application and the second application is applicable.

4 . The method of claim 1 , wherein the association information further comprises a schedule for which the association between the first application and the second application is valid or active.

5 . The method of claim 1 , wherein the association information further comprises an association control element to control whether the association between the first application and the second application is enabled or disabled.

6 . The method of claim 1 , wherein the association information further comprises identifiers of the first WTRU and second WTRU.

7 . The method of claim 1 , wherein the first application server and the second application server each comprise an edge application server.

8 . A method performed by a service resident in a network, the method comprising:
receiving, from a service resident on a first WTRU, information for an association between a first application of the first WTRU and a second application resident on a second WTRU, wherein the association information comprises identifiers of the first application and the second application and a type of application service required by the first application and the second application to interact with each other; assigning, based on the association information, the first application and the second application to a first application server providing the type of service required by the first application and the second application to interact with each other; detecting the first WTRU's location is no longer in a service area of the first application server; and assigning, based on the association information, the first application and the second application to a second application server providing the type of service required by the first application and the second application to interact with each other.

9 . The method of claim 8 , wherein the association information further comprises association service key performance indicators (KPIs) comprising one or more of an aggregated connection bandwidth to the service required by the first application and the second application, or an aggregated rate of requests to the service required by the first application and the second application.

10 . The method of claim 9 , wherein the association information further comprises a service area for which the association between the first application and the second application is applicable.

11 . The method of claim 10 , wherein the association information further comprises a schedule for which the association between the first application and the second application is valid or active.

12 . The method of claim 11 , wherein the association information further comprises an association control element to control whether the association between the first application and the second application is enabled or disabled.

13 . The method of claim 12 , wherein the association information further comprises identifiers of the first WTRU and second WTRU.

14 . The method of claim 8 , wherein the first application server and the second application server each comprise an edge application server.

15 . An apparatus, the apparatus being a first wireless transmit/receive unit (WTRU) comprising a processor, and memory storing instructions, that when executed by the processor cause the apparatus to:
receive, from a first application resident on the first WTRU, information for an association between the first application and a second application resident on a second WTRU, wherein the association information comprises identifiers of the first and second applications and a type of application service required by the first application and the second application to interact with each other; send the association information to a service in a network such that the first application and the second application are assigned by a service in the network to a first application server providing the type of service required by the first application and the second application to interact with each other; detect the first WTRU's location is no longer in a service area of the first application server; and send a request to the service in the network such that the first application and the second application are assigned by the service in the network to a second application server providing the type of service required by the first application and the second application to interact with each other.

16 . The apparatus of claim 15 , wherein the association information further comprises association service key performance indicators (KPIs) that further comprise one or more of: an aggregated connection bandwidth to the application service required by the first and second applications, or an aggregated rate of requests to the application service required by the first and second applications.

17 . The apparatus of claim 15 , wherein the association information further comprises a service area for which the association between the first application and the second application is applicable.

18 . The apparatus of claim 15 , wherein the association information further comprises a schedule for which the association between the first application and the second application is valid or active.

19 . The apparatus of claim 15 , wherein the association information further comprises an association control element to control whether the association between the first application and the second application is enabled or disabled.

20 . The apparatus of claim 15 , wherein the association information further comprises identifiers of the first WTRU and second WTRU.
