Classification: CPC H  G | IPC H

Claim 15:
16. A communications system, comprising an operations support system/business support system (OSS/BSS), a network functions virtualization orchestrator (NFVO), a virtualized infrastructure manager (VIM), and a virtualized network function manager (VNFM);
wherein the OSS/BSS is configured to:
send virtualized network function description information (VNFD) to the NFVO;

wherein the NFVO is configured to:
receive the VNFD from the OSS/BSS, wherein the VNFD is for instantiating a virtualized network function (VNF), the VNFD comprises first indication information and resource requirement information of a first internal network, and the first indication information indicates that the resource requirement information of the first internal network is externally visible;
send an external network instantiation request to the VIM; and
send a VNF instantiation request to the VNFM;

wherein the VIM is configured to:
receive the external network instantiation request; and
instantiate, using the external network instantiation request and based on the resource requirement information of the first internal network, an external network connected to the VNF; and

wherein the VNFM is configured to:
receive the VNF instantiation request; and
instantiate, using the VNF instantiation request and based on the VNFD, the VNF.
