[0106] Step 502: NSMF converts the user service demand information into end-to-end network slicing demand information, and determines whether there is an existing network slicing instance that meets the network slicing demand. If there is no existing network slicing instance that meets the network slicing demand, a template that meets the network slicing demand is matched to generate an end-to-end network slicing instance identifier.

[0107] Step 503: Decompose the end-to-end network slicing requirements into requirements for each network slice subnet of the non-shared network, and send them to each NSSMF, carrying the end-to-end network slice instance identifier.

[0108] Step 504: Decompose the end-to-end network slicing requirements into network slicing requirements for the shared network and send them to the SNSMF, carrying the end-to-end network slicing instance identifier.

[0109] Step 505: SNSMF generates network slice maintenance management information of the shared network and the network slice instance identifier of the shared network, and binds the identifier with the end-to-end network slice instance identifier.

[0110] Step 506: Decompose the network slice demand for the shared network into the network slice subnet demand for the shared network, and send it to each SNSSMF, carrying the end-to-end network slice instance identifier and the network slice instance identifier of the shared network.

[0111] Step 507: Each NSSMF generates maintenance management information of the network slice subnet of the non-shared network and the network slice subnet instance identifier of the non-shared network, and binds the identifier with the end-to-end network slice instance identifier.

[0112] Step 508: NSSMF passes the network slice subnet requirements for the non-shared network to the MANO functional entity, and completes the orchestration of the virtualized network slice subnet resource part by calling the network service orchestration function of NFVO.

[0113] Step 509: MANO allocates virtualized resources, generates a network slice subnet resource instance of a non-shared network, and configures the resource instance.

[0119] Step 515: MANO notifies SNSSMF of the resource instance generation result of the network slice subnet of the shared virtualized network.

[0120] Step 516: Each sub-domain SNSSMF notifies SNSMF of the result of generating the network slice subnet instance of the shared network, carrying the network slice subnet instance identifier of the shared network.

[0121] Step 517: SNSMF notifies NSMF of the result of generating the network slice instance of the shared network, which carries the network slice instance identifier of the shared network and the network slice subnet instance identifier of the shared network.

[0122] Step 518: NSMF binds the end-to-end network slice instance identifier with the network slice subnet instance identifier of the non-shared network, the network slice instance identifier of the shared network, and the network slice subnet instance identifier of the shared network.

[0123] Step 519: NSMF performs end-to-end network slicing configuration, including slice service-related configuration, network connectivity and other configurations.

[0124] Step 520: NSMF notifies CSMF of the end-to-end network slice creation result, carrying the end-to-end network slice instance identifier.

[0125] By adopting the technical solution of the embodiment of the present invention, the end-to-end network slicing demand is split into the network slicing subnet demand for the non-shared network and the network slicing demand for the shared network through a non-shared network and a co-built shared network, and the network slicing demand for the shared network is transmitted to the SNSMF of the shared network, thereby realizing network slicing management and end-to-end network slicing management of the co-built shared network.
