Method for managing a virtual radio access network and method for calibrating a software component

1. A method for managing a virtual radio access network which serves a radio cell, comprising:

selecting, based on a radio access technology of the radio cell, a construction scheme for the virtual radio access network in a repository;

querying, from the repository, at least one software component associated to the construction scheme, wherein the software component represents a virtualized network function of the virtual radio access network; and

setting up, using the software component, the virtualized network function on a runtime platform according to the construction scheme, wherein the setting up comprises allocating a number of processor cores of the runtime platform to the software component which represents the virtualized network function based on a total number of processor cores of the runtime platform and/or information on a default allocation setting stored in the repository together with the software component;

setting up a clone of the software component representing the virtualized network function on the runtime platform if a first load condition is satisfied; and

8. The method of claim 7 , wherein the construction scheme for the virtual radio access network is further selected based on a number of users to be served by the radio cell and/or a configuration of the runtime platform and/or a constraint of the radio cell's radio access technology.

9. The method of claim 7 , further comprising:

monitoring a load of the number of processor cores allocated to the software component; and

changing the number of the processor cores allocated to the software component if a first load condition is satisfied.

10. The method of claim 7 , wherein the virtualized network function represents at least part of a communication protocol used in the radio cell's radio access technology.

11. A non-transitory computer-readable medium storing program instructions that, when executed by a computer or a processor, cause at least one computing platform to perform the method of claim 7 .

12. A method for managing a virtual radio access network which serves a radio cell, comprising:

selecting, based on a radio access technology of the radio cell, a construction scheme for the virtual radio access network in a repository;

querying, from the repository, at least one software component associated to the construction scheme, wherein the software component represents a virtualized network function of the virtual radio access network;

setting up, using the software component, the virtualized network function on a runtime platform according to the construction scheme, wherein the setting up comprises allocating a number of processor cores of the runtime platform to the software component which represents the virtualized network function based on a total number of processor cores of the runtime platform and/or information on a default allocation setting stored in the repository together with the software component;
