Abstract

Embodiments of the present application relate to the field of computer technologies, and provide a service migration method, apparatus, and system. The method is performed by a target mobile edge platform, including: receiving a service migration request sent by a source mobile edge platform; obtaining a service endpoint corresponding to a service identifier; and sending a service migration response to the source mobile edge platform. In this way, a problem of migrating a service from the source mobile edge platform to the target mobile edge platform is resolved, and it can be ensured that after the service is migrated from the source mobile edge platform to the target mobile edge platform, a local mobile edge platform that subscribes to the service on the source mobile edge platform can continue to correctly use the service migrated to the target mobile edge platform.

First claim

What is claimed is:

1. A service migration apparatus, wherein the apparatus comprises: a processor and a memory, wherein the memory stores program instructions, and the processor is configured to execute the program instructions stored in the memory to perform the following operations:
receiving a service migration request from a source mobile edge platform, wherein the service migration request is used to request to migrate a service provided by a service provider, the service migration request comprises a service identifier of the service, and the service identifier is used to identify the service in one or more services;
obtaining a service endpoint corresponding to the service identifier, wherein the service endpoint is an access address used when the service provider provides the service;
sending a service migration response to the source mobile edge platform;
sending a route update request to a routing table controller, wherein the route update request comprises the service endpoint and an IP address of a target mobile edge platform, and the route update request is used to request the routing table controller to update a path pointing to the service endpoint;
receiving a subscription request from a local mobile edge platform, wherein the subscription request is used to subscribe to the service on the target mobile edge platform; and
sending service information to the local mobile edge platform, wherein the service information comprises the service identifier and the service endpoint.

2. The apparatus according to claim 1 , wherein the operations further comprise: generating a target temporary service endpoint based on the service endpoint and an Internet Protocol (IP) address of a target mobile edge platform, wherein the target temporary service endpoint is an access address used when the service provider provides the service by using the target mobile edge platform.

3. The apparatus according to claim 1 , wherein the operations further comprise:
storing a correspondence between the service endpoint and a tunnel, wherein the tunnel is a tunnel between the local mobile edge platform and a target mobile edge platform, the local mobile edge platform is a mobile edge platform on which a service consumer using the service is located, and the tunnel is used to transmit data between the service consumer and the service provider.

4. The apparatus according to claim 2 , wherein the operations further comprise:
receiving a subscription request from the local mobile edge platform, wherein the subscription request is used to subscribe to the service on the target mobile edge platform; and
sending service information to the local mobile edge platform, wherein the service information comprises the service identifier and the target temporary service endpoint.

5. The apparatus according to claim 1 , wherein the operations further comprise: obtaining, from the service migration request, the service endpoint corresponding to the service identifier; or
receiving the service endpoint that is corresponding to the service identifier from the service provider.

6. The apparatus according to claim 5 , wherein the operations further comprise:
receiving a registration request from the service provider, wherein the registration request comprises the service endpoint corresponding to the service identifier; or
sending a re-registration indication to the service provider, and receiving the registration request from the service provider, wherein the registration request comprises the service endpoint corresponding to the service identifier.

7. A service migration apparatus, wherein the apparatus comprises:
a processor and a memory, wherein the memory stores program instructions, and the processor is configured to execute the program instructions stored in the memory to perform the following operations:
sending a service migration request to a target mobile edge platform, wherein the service migration request is used to request to migrate a service provided by a service provider, the service migration request comprises a service identifier of the service, and the service identifier is used to identify the service in one or more services;
receiving a service migration response from the target mobile edge platform; sending service migration information to a local mobile edge platform that subscribes to the service, wherein the service migration information comprises the service identifier and an Internet Protocol (IP) address of the target mobile edge platform, and the local mobile edge platform is a mobile edge platform on which a service consumer using the service is located; and
receiving a subscription cancellation request from the local mobile edge platform, wherein the subscription cancellation request is used to cancel the subscribed service on a source mobile edge platform.

8. The apparatus according to claim 7 , wherein the operations further comprise:
sending the service migration request to the target mobile edge platform when determining that the service needs to be migrated; or
receiving a service migration request from the service provider, wherein the service migration request is sent by the service provider when the service provider determines that the service needs to be migrated; and sending the service migration request to the target mobile edge platform.

9. The apparatus according to claim 7 , wherein the operations further comprise:
deleting a correspondence between a service endpoint and a tunnel, wherein the service endpoint is an access address used when the service provider provides the service, the tunnel is a tunnel between the local mobile edge platform and the source mobile edge platform, and the tunnel is used to transmit data between the service consumer and the service provider.

10. A service migration apparatus, wherein the apparatus comprises:
a processor and a memory, wherein the memory stores program instructions, and the processor is configured to execute the program instructions stored in the memory to perform the following operations:
receiving service migration information from a source mobile edge platform, wherein the service migration information is used to indicate that a service provided by a service provider has been migrated to a target mobile edge platform, the service migration information comprises a service identifier of the service and an Internet Protocol (IP) address of the target mobile edge platform, and the service identifier is used to identify the service in one or more services, wherein the service migration information further comprises a target temporary service endpoint of the service, and the target temporary service endpoint is an access address used when the service provider provides the service by using the target mobile edge platform; and
sending a subscription cancellation request to the source mobile edge platform based on the service migration information, wherein the subscription cancellation request is used to cancel the subscribed service on the source mobile edge platform;
sending a subscription request to the target mobile edge platform based on the IP address of the target mobile edge platform, wherein the subscription request is used to subscribe to the service on the target mobile edge platform; and
receiving service information from the target mobile edge platform, wherein the service information comprises the service identifier.

11. The apparatus according to claim 10 , wherein the operations further comprise:
sending a tunnel deletion request to a local service network function entity, wherein the tunnel deletion request is used to delete a tunnel between a local mobile edge platform and the source mobile edge platform;
