COMMUNICATION SYSTEM, PROVIDER NODE, COMMUNICATION NODE AND METHOD FOR PROVIDING A VIRTUAL NETWORK FUNCTION TO A CUSTOMER NODE
FIG2 schematically illustrates a communication system according to an embodiment
FIG2 schematically illustrates a communication system 100 according to an embodiment of the invention. In some advantageous modification and as illustrated in FIG2, the communication node 130 may comprise a retrieving module 132. The retrieving module 132 is adapted to retrieve a template of the selected virtual network function from a data repository system. Thereby, the template of the selected virtual network function can be provided by the data repository system and it is not required to permanently store the template locally in the communication node or to transfer the template by the deployment signal or to store it in the distributed database, which may make the deployment of the virtual network function more efficient and/or allow a high flexibility of virtual network functions to be provided.

['1. A provider node (110) comprising: a retrieving module (112) adapted to retrieve a notification signal, the notification signal being indicative of a selected one of a plurality of virtual network functions and at least one customer node to which the selected virtual network function is to be provided; a validation module (114) adapted to establish service level agreement data, the service level agreement data at least representing a configuration of the selected virtual network function and the at least one customer node, and to validate the service agreement level data, based on the notification signal; and a deployment module (116) adapted to selectively transmit a deployment signal to a communication node depending on the validating of the service level agreement data for providing the selected virtual network function to the at least one customer node, the deployment signal being indicative of the at least one customer node, the selected virtual network function and its configuration.', '7. A communication node (130) comprising: a receiving module (136) adapted to receive a deployment signal indicative of at least one customer node, a selected one of a plurality of virtual network functions, and a configuration of the selected virtual network function; and a management module (138) adapted to provide the selected virtual network function according to its configuration to the at least one customer node.', '8. The communication node (130) of claim 7, further comprising: a state reporting module (134) adapted to determine status report data, the status report data being indicative of whether the selected virtual network function and according to which configuration is provided to the at least one customer node, and to transmit the status report data to a distributed database (20).', '10. A communication system (100) comprising the provider node (110) of any one of claims 1 to 6 and the communication node (130) of any one of claims 7 to']
