Network slice management method, device, and system

A network slice management apparatus, comprising a processor, a memory, and a transceiver, wherein

• the processor is configured to obtain capability description information of a network slice, wherein the capability description information of the network slice comprises at least one of a feature of the network slice and a deployment capability of the network slice;
• the transceiver is configured to send a notification message to a service management unit, wherein the notification message carries the capability description information of the network slice;
• the transceiver is further configured to receive a network slice management request message sent by the service management unit, wherein the network slice management request message carries deployment information of the network slice, and the deployment information of the network slice corresponds to the deployment capability of the network slice;
• the processor is further configured to manage the network slice based on the deployment information of the network slice;
• and
• the processor is configured to obtain a network slice template, and obtain the capability description information of the network slice from the network slice template, wherein the network slice template comprises the capability description information of the network slice.

A system for managing a network slice, comprising a network management unit and a service management unit;

• wherein
• the network management unit comprises a first processor and a first computer storage medium, the first computer storage medium is configured to store computer software instructions such that the network management unit is configured to obtain capability description information of the network slice, wherein the capability description information of the network slice comprises at least one of a feature of the network slice and a deployment capability of the network slice, and to send a notification message to a service management unit, wherein the notification message carries the capability description information of the network slice;
• the service management unit comprises a second processor and a second computer storage medium, the second computer storage medium is configured to store computer software instructions such that the service management unit is configured to receive the notification message, wherein the capability description information of the network slice is used to describe a capability of the network slice, and to manage the network slice based on the capability description information of the network slice;
• the service management unit is configured to send a network slice management request message to the network management unit, wherein the network slice management request message carries deployment information of the network slice, and the deployment information of the network slice corresponds to the deployment capability of the network slice;
• and
• the network management unit is configured to manage the network slice based on the deployment information of the network slice;
• wherein the network management unit is configured to obtain capability description information of the network slice by:
• obtaining, by the network management unit, a network slice template, wherein the network slice template comprises the capability description information of the network slice;
• and
• obtaining, by the network management unit, the capability description information of the network slice from the network slice template.
