Classification: CPC H  G | IPC H

Claim 4:
5. A communications system comprising:
a network functions virtualization orchestrator (NFVO) comprising:
a first transceiver; and
a first processor coupled to the first transceiver and configured to send, using the first transceiver, a virtualized network function (VNF) instantiation request message requesting to instantiate a VNF to start a VNF instance for an application for a network service (NS), wherein the application is not combined with another application into the NS and is not split into functional components or services;

a VNF manager (VNFM) coupled to the NFVO and comprising:
a second transceiver; and
a second processor coupled to the second transceiver and configured to:
receive, by the second transceiver, the VNF instantiation request message;
obtain, based on a quality of service (QoS) attribute of the VNF and a preset mapping relationship between the QoS attribute and a virtual resource location area, the virtual resource location area as a target virtual resource location area for deploying the VNF instance; and
send, using the second transceiver, a virtual resource allocation request message requesting to allocate a virtual resource for deploying the VNF instance, wherein the virtual resource allocation request message carries first information about the target virtual resource location area; and

a virtualized infrastructure manager (VIM) coupled to the VNFM and comprising:
a third transceiver; and
a third processor coupled to the third transceiver and configured to:
receive, using the third transceiver, the virtual resource allocation request message; and
send, using the third transceiver to the VNFM, a virtual resource allocation response message indicating second information about a target virtual resource for deploying the VNF instance, wherein the target virtual resource is located in the target virtual resource location area,

wherein the second transceiver is further configured to receive the virtual resource allocation response message, and
wherein the second processor is further configured to instantiate, based on the second information, the VNF on the target virtual resource.
