Abstract

A method for managing and orchestrating virtual application functions jointly with virtual network functions is done through a single management and orchestration (MANO) framework within a network. The method includes creating, by a system for (virtual) application function and virtual network function management and orchestration, at least one service or service chain that considers or comprises at least one (virtual) network application and/or at least one virtual network function. A virtual application function (VAF) entity is provided as a container for network applications together with a VAF manager (VAFM) for the VAF.

First claim

The invention claimed is:

1. A method for jointly managing and orchestrating virtual application functions and virtual network functions through a single management and orchestration (MANO) framework within a network, the method comprising:
creating, by a MANO Orchestrator of the MANO framework, at least one virtual network application and a mobile edge computing (MEC) service platform, the MEC service platform including one or more virtual network functions (VNFs);
providing a virtual application function (VAF) as a container for the at least one virtual network application, the VAF being mapped and connected to the one or more VNFs of the MEC platform such that the VAF is configured to utilize services provided by the one or more VNFs of the MEC platform;
providing, in the MANO framework, a VAF manager (VAFM) configured to perform lifecycle management for the VAF and a VNF manager (VNFM) configured to perform lifecycle management for the one or more VNFs of the MEC platform;
providing a first set of interfaces, the first set of interfaces including an interface between the VAFM and the MANO Orchestrator, an interface between the VAF and the VAFM, and an interface between the VAFM and a virtualized infrastructure manager (VIM) of the MANO framework; and
providing a second set of interfaces, the second set of interfaces including an interface between the VNFM and the MANO Orchestrator, an interface between the at least one VNF and the VNFM, and an interface between the VNFM and the VIM of the MANO framework.

2. The method according to claim 1 , wherein the MANO framework includes a combination or joint of a management system architecture for virtual application functions with a network function virtualization (NFV) MANO architecture.

3. The method according to claim 1 , wherein the VAFM is configured to interact with the VNFM to jointly perform MANO operations for the VAF and the one or more VNFs of the service platform.

4. The method according to claim 2 , wherein the management system architecture for virtual application functions is combined or joint with the NFV MANO architecture under a single platform.

5. The method according to claim 2 , further comprising providing a service platform of the management system architecture for virtual application functions by a virtual function within the NFV MANO architecture.

6. The method according to claim 5 , wherein the service platform is handled as a single VNF, a VNF is provided for each service instance of the service platform, or a VNF is provided for a selected set of service instances of the service platform.

7. The method according to claim 2 , wherein a platform management system is mapped to or combined with at least one manager of the NFV MANO architecture.

8. The method according to claim 1 , wherein the VAF and the VAFM are provided as internal modules of a VNF and the VNFM, respectively.

9. The method according to claim 1 , wherein a virtual network function or virtual application function or MEC function triggers the system for virtual application function and virtual network function management and orchestration to improve or optimize a performance of an attached user or to provide changes or rearrangements in virtualized or virtual functions of a core network.

10. The method according to claim 1 , wherein the MANO orchestrator is an orchestrator for both virtual application functions and virtual network functions.

11. The method according to claim 1 , wherein the at least one virtual network application includes at least one MEC application.

12. The method according to claim 1 , further comprising performing, by the VAFM, MANO operations for the VAF and performing, by the VNFM, MANO operations for the one or more VNFs of the service platform.

13. The method according to claim 12 , wherein the MANO operations for the VAF are triggered by performance measurements of the VAF, and wherein the MANO operations for the one or more VNFs of the service platform are triggered by an assessment, by the VAFM, of the performance level provided by the one or more VNFs of the service platform.

14. The method according to claim 12 , wherein a runtime process of the VAF triggers the MANO operations for the one or more VNFs of the service platform.

15. The method according to claim 13 , wherein the performance measurements of the VAF indicate whether a user device experiences minimum service requirements for the VAF.

16. The method according to claim 12 , wherein the MANO operations for the VAF include a context transfer of the VAF from a source cell to a target cell, and wherein the MANO operations for the one or more VNFs of the service platform include a scaling out of a Radio Network Information Service (RNIS) in the target cell.

17. A network for jointly managing and orchestrating virtual application functions, virtual network functions, and network applications, the network comprising:
a MANO Orchestrator configured to create at least one virtual network application and a mobile edge computing (MEC) service platform, the MEC service platform including one or more virtual network functions (VNFs);
a virtual application function (VAF), the VAF being a container for the at least one virtual network application, the VAF being mapped and connected to the one or more VNFs of the MEC platform such that the VAF is configured to utilize services provided by the one or more VNFs of the MEC platform;
a VAF manager (VAFM) configured to perform lifecycle management for the VAF; and
a VNF manager (VFNM) configured to perform lifecycle management for the at least one VNF;
wherein a first set of interfaces is provided that includes an interface between the VAFM and the MANO Orchestrator, an interface between the VAF and the VAFM, and an interface between the VAFM and a virtualized infrastructure manager (VIM) of the MANO framework, and
wherein a second set of interfaces is provided that includes an interface between the VNFM and the MANO Orchestrator, an interface between the at least one virtual network function and the VNFM, and an interface between the VNFM and the VIM of the MANO framework.

18. An orchestrator entity configured to perform the method for jointly managing and orchestrating virtual application functions and virtual network functions according to claim 1 .
