|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||NETWORK SLICE MANAGEMENT METHOD, APPARATUS AND SYSTEM|
A network slice management method, apparatus and system. The system comprises a virtual network function manager (VNFM), a network slice manager (NSLM), a second-level controller (GC), and at least one forwarder. The GC is in communication connection with each of the at least one forwarder. The VNFM is used for controlling, according to a first creation request message, the GC to create a first virtual controller used for managing a first network slice. The NSLM is used for controlling, according to a second creation request message, the first forwarder to create at least one first virtual forwarder, the first creation request message and the second creation request message carrying an identifier of the first network slice. The GC and the first forwarder are used for establishing a management channel between the first virtual controller and the at least one first virtual forwarder, and transmitting control information for the first network slice through the management channel. In this way, the practicability of the network slice technology can be improved.
