sending, by the third management unit, the network slice management request to the first management unit, wherein the network slice management request carries the instance information or the indication information of the transport network manager.

6. The method according to claim 1 , wherein

the first management unit comprises network management (NM) or domain management (DM).

7. A network management unit comprising:

at least one processor; and

non-transitory computer-readable storage medium coupled to the at least one processor storing programming instructions for execution by the at least one processor, the programming instructions to instruct the at least one processor to:

receive a network slice management request, wherein the network slice management request carries instance information or indication information of a transport network manager, and the indication information is used to determine the instance information of the transport network manager; and

send a transmission management request to a corresponding transport network manager based on the instance information of the transport network manager, wherein the transmission management request is used to deploy a transmission network, wherein the indication information of the transport network manager comprises: tenant information, a network slice type, a service type, location information, and a bandwidth, wherein the indication information of the transport network manager further includes indication information of a network slice template, wherein the indication information of the network slice template is used to obtain the network slice template, and, the network slice template includes the instance information of the transport network manager and the indication information of the network slice template includes network slice requirement information including network slice type, latency, coverage, and quantity of users.

8. The network management unit according to claim 7 , wherein, when the network slice management request carries the indication information of the transport network manager, before the network management unit sends the transmission management request to the corresponding transport network manager based on the instance information of the transport network manager, the at least one processor is configured to:

determine the instance information of the transport network manager based on the indication information of the transport network manager.

9. The network management unit according to claim 7 , wherein the at least one processor is configured to: receive instance information of at least one transport network manager.

10. The network management unit according to claim 7 , wherein the indication information of the transport network manager comprises indication information of a network slice template, wherein the indication information of the network slice template is used to obtain the network slice template; and

the network slice template comprises the instance information of the transport network manager.

11. The network management unit according to claim 7 , wherein the instance information of the transport network manager comprises one or more of: an identifier of the transport network manager, provider information of the transport network manager, a network address of the transport network manager, a service address of the transport network manager, and access security information of the transport network manager.

12. A system for network slice management comprising:

a first management unit, wherein the first management unit comprises network management (NM) or domain management (DM);

a third management unit configured to determine instance information of a transport network manager or indication information and to send a management request to the first management unit, wherein the management request carries the instance information of the transport network manager or indication information, and

wherein, the first management unit is configured to receive the management request, wherein the indication information is for determining the instance information of the transport network manager, and to send a transmission management request to a corresponding transport network manager based on the instance information of the transport network manager, wherein the transmission management request is for deploying a transmission network, wherein the indication information of the transport network manager comprises: tenant information, a network slice type, a service type, location information, and a bandwidth, wherein the indication information of the transport network manager further includes indication information of a network slice template, wherein the indication information of the network slice template is used to obtain the network slice template, and, the network slice template includes the instance information of the transport network manager and the indication information of the network slice template includes network slice requirement information including network slice type, latency, coverage, and quantity of users.
