Abstract

Claims (60)

1 . An apparatus of a source edge data network, the apparatus comprising:

a communication interface configured to receive signaling that indicates an edge application service relocation for transferring a user equipment (UE) session for a UE to a target edge data network; and

a processor operably coupled to the communication interface, the processor configured to:

identify an edge application service in the source edge data network processing media content corresponding to the UE session;

generate a list of requirements for running the edge application service;

transmit a request for the edge application service relocation to the target edge data network, the request including the list of requirements;

receive a response to the request, wherein the response indicates instantiation of the edge application service in the target edge data network is in progress or complete; and

enable the edge application service relocation for the user equipment from the edge application service at the source edge data network to an edge application service at the target edge data network.

2 . The apparatus of claim 1 , wherein:

when instantiation of the edge application service in the target edge data network is in progress, a temporary media buffer is available for the UE session, and

the processor is further configured to enable service continuity of the UE session using the temporary media buffer until instantiation of the edge application service in the target edge data network is completed.

3 . The apparatus of claim 2 , wherein the processor is further configured to instruct the UE to duplicate media content of the UE session to the apparatus and the temporary media buffer.

4 . The apparatus of claim 1 , wherein the processor is further configured to:

receive a response to the request indicating that key performance indicators cannot be guaranteed by the target edge data network, and

provide an alternative list of requirements to the target edge data network.

5 . The apparatus of claim 4 , wherein the alternative list of requirements has a reduced application performance compared to the list of requirements.

6 . The apparatus of claim 4 , wherein the alternative list of requirements indicates partial media processing at the target edge data network and remaining media processing at the source edge data network.

7 . The apparatus of claim 1 , wherein the processor is further configured to:

receive a response to the request that indicates instantiation of multiple edge application services in the target edge data network for the edge application service relocation for the edge application service at the source edge data network, and

enable the edge application service relocation for the UE session from the edge application service at the source edge data network to the multiple edge application services at the target edge data network.

8 . The apparatus of claim 1 , wherein:

the processor is further configured to access an application service directory that includes mapping information for splitting or fusing the edge application service to facilitate the edge application service relocation; and

the mapping information includes:

(i) a forward mapping from multiple processing descriptors in the source edge data network to a single processing descriptor in the target edge data network, or

(ii) a reverse mapping from a single processing descriptor in the source edge data network to multiple processing descriptors in the target edge data network.

9 . A method for an edge application service relocation from a source edge data network to a target edge data network, the method comprising:

receiving signaling that indicates an edge application service relocation for transferring a user equipment (UE) session to the target edge data network;

identifying an edge application service in the source edge data network processing media content corresponding to the UE session;

generating a list of requirements for running the edge application service;

transmitting a request for the edge application service relocation to the target edge data network, the request including the list of requirements;

receiving a response to the request, wherein the response indicates instantiation of the edge application service in the target edge data network is in progress or complete; and

enabling the edge application service relocation for the UE session from the edge application service at the source edge data network to an edge application service at the target edge data network.

10 . The method of claim 9 , wherein when instantiation of the edge application service in the target edge data network is in progress, a temporary media buffer is available for the UE session, and

the method further comprising enabling service continuity of the UE session using the temporary media buffer until instantiation of the edge application service in the target edge data network is completed.

11 . The method of claim 10 , further comprising:

instructing the UE to duplicate media content of the UE session to the source edge data network and the temporary media buffer.

12 . The method of claim 9 , further comprising:

receiving a response to the request indicating that key performance indicators cannot be guaranteed by the target edge data network, and

providing an alternative list of requirements to the target edge data network.

13 . The method of claim 12 , wherein the alternative list of requirements has a reduced application performance compared to the list of requirements.

14 . The method of claim 12 , wherein the alternative list of requirements indicates partial media processing at the target edge data network and remaining media processing at the source edge data network.

15 . The method of claim 9 , further comprising:

receiving a response to the request that indicates instantiation of multiple edge application services in the target edge data network for the edge application service relocation for the edge application service at the source edge data network, and

enabling the edge application service relocation for the UE session from the edge application service at the source edge data network to the multiple edge application services at the target edge data network.

16 . The method of claim 9 , further comprising:

accessing an application service directory that includes mapping information for splitting or fusing the edge application service to facilitate the edge application service relocation,

wherein the mapping information includes:

(i) a forward mapping from multiple processing descriptors in the source edge data network to a single processing descriptor in the target edge data network, or

(ii) a reverse mapping from a single processing descriptor in the source edge data network to multiple processing descriptors in the target edge data network.

17 . An apparatus of a target edge data network, the apparatus comprising:

a communication interface configured to receive, from a source edge data network, a request for an edge application service relocation for a user equipment (UE) session receiving media content from an edge application service at the source edge data network, the request including a list of requirements to the target edge data network; and

a processor operably coupled to the communication interface, the processor configured to:

generate an edge application service based on the list of requirements;

transmit a response to the request, wherein the response indicates instantiation of the edge application service in the target edge data network is in progress or complete; and

enable the edge application service relocation for the UE session from the edge application service at the source edge data network to the generated edge application service based on the list of requirements.

18 . The apparatus of claim 17 , wherein the processor is further configured to:

transmit a response to the request indicating that key performance indicators cannot be guaranteed by the target edge data network, and

receive an alternative list of requirements to the target edge data network.

19 . The apparatus of claim 18 , wherein the alternative list of requirements has a reduced application performance compared to the list of requirements.

20 . The apparatus of claim 18 , wherein the alternative list of requirements indicates partial media processing at the target edge data network and remaining media processing at the source edge data network.
