NETWORK FUNCTIONS VIRTUALIZATION
First Claim
1. A virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate instantiation of a virtualized network function (VNF) instance, the VNFM comprising one or more processors configured to:
- receive, at the VNFM, a request to instantiate a new VNF instance from a network manager (NM) via a network function virtualization (NFV) orchestrator (NFVO), the request including VNF instantiation information;
send a request to a virtualized infrastructure manager (VIM) for allocating virtual resources for the new VNF instance based on the VNF instantiation information;
receive, at the VNFM, an acknowledgement from the VIM after successful allocation of the virtualized resources for the new VNF instance; and
instantiate, at the VNFM, the new VNF instance and send an acknowledgement of the new VNF instance to the NFVO, wherein the new VNF instance is operable to ease congestion at an overloaded non-virtualized network element in the mixed wireless network.

Abstract
Technology for a virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate instantiation of a virtualized network function (VNF) instance is disclosed. The VNFM can receive a request to instantiate a new VNF instance from a network manager (NM) via a network function virtualization (NFV) orchestrator (NFVO), the request including VNF instantiation information. The VNFM can send a request to a virtualized infrastructure manager (VIM) for allocating virtual resources for the new VNF instance based on the VNF instantiation information. The VNFM can receive an acknowledgement from the VIM after successful allocation of the virtualized resources for the new VNF instance. The VNFM can instantiate the new VNF instance and send an acknowledgement of the new VNF instance to the NFVO, wherein the new VNF instance is operable to ease congestion at an overloaded non-virtualized network element in the mixed wireless network.

9. A virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate termination of a virtualized network function (VNF) instance, the VNFM comprising one or more processors configured to:
-
receive, at the VNFM, a request to terminate an existing VNF instance from a network manager (NM) via a network function virtualization (NFV) orchestrator (NFVO); initiate termination of the existing VNF instance; and send an acknowledgment to the NFVO after successfully terminating the existing VNF instance, wherein the NFVO is configured to request a virtualized infrastructure manager (VIM) to delete virtualized resources used by one or more virtualization deployment units (VDUs) of the existing VNF instance. - View Dependent Claims (10, 11, 12, 13, 14)

15. A virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate expansion of virtualized resources for a virtualized network function (VNF) instance, the VNFM comprising one or more processors configured to:
-
determine, at the VNFM, to expand virtualized resources for an existing VNF instance when the existing VNF instance is overloaded; send a request to a virtualized infrastructure manager (VIM) for expanding the virtualized resources for the existing VNF; and receive, at the VNFM, an acknowledgement from the VIM after additional virtualized resources are successfully allocated for the existing VNF instance. - View Dependent Claims (16, 17, 18, 19)

20. A virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate contraction of virtualized resources for a virtualized network function (VNF) instance, the VNFM comprising one or more processors configured to:
-
determine, at the VNFM, to contract virtualized resources for an existing VNF instance when the virtualized resources are excessive for the existing VNF instance; send a request to a virtualized infrastructure manager (VIM) for contracting the virtualized resources for the existing VNF; and receive, at the VNFM, an acknowledgement from the VIM after the virtualized resources are successfully contracted for the existing VNF instance. - View Dependent Claims (21, 22, 23, 24, 25, 26)
