Method and system for authorizing the communication of a network node

1. A method for authorizing communication of a network node with another component of a communication network, the method comprising:

forming an NFC connection between the network node and a defined mobile communication terminal; and

authorizing the network node for the communication with the other component only when a geographic position of the network node is within four meters of the position of the defined mobile communication terminal; and

carrying out the communication to conduct a firmware update or an update of operating parameters of the network node;

wherein the network node and the defined mobile communication terminal are in a permanent NFC connection during the communication; and

the defined mobile communication terminal includes a correspondingly certified mobile communication terminal.

2. The method as claimed in claim 1 , further comprising sending authorization to the network node from the mobile communication terminal.

3. The method as claimed in claim 1 , further comprising receiving authorization at the network node directly from a cloud server.

4. The method as claimed in claim 1 , further comprising requesting an acknowledgement from the mobile communication terminal following receipt of authorization by the network node via the NFC connection.

5. The method as claimed in claim 1 , further comprising, following receipt of authorization, requesting an acknowledgment from the mobile communication terminal via the NFC connection to a certification server.

6. The method as claimed in claim 1 , further comprising receiving authorization at the mobile communication terminal via a certification server.

7. The method as claimed in claim 1 , further comprising allowing communication from the network node to the communication network only if the mobile communication terminal is located within a defined distance of the network node.

8. The method as claimed in claim 1 , further comprising permitting a write access to a memory of the network node only following a completed authorization.

9. A system for authorizing communication between network nodes, the system comprising:

a communication network; and

a first network node;

wherein the first network node forms an NFC connection with a defined mobile communication terminal and stays in a permanent NFC connection with the defined mobile communication terminal throughout the communication;

wherein the communication network only authorizes the first network node for communication with a second network node when a geographical position of the network node is within four meters of a position of the defined mobile communication terminal;

the first network node carrying out the communication to conduct a firmware update or an update of operating parameters of the first network node; and

the defined mobile communication terminal includes a correspondingly certified mobile communication terminal.

10. The system as claimed in claim 9 , wherein after receiving the authorization, the network node allows a write access to a memory of the network node.
