      summary: Global System for Mobile Communications Set the desired QoS behaviour for a user home device
      description: 'Set the desired QoS behaviour for the traffic corresponding to the user home device matching the input criteria. **QoS behaviour is determined by the service class provided by the API Client. Setting `standard` service class restores default traffic treatment for the target home device.**


        - The operation is executed for the user whose `sub` is in the access token used to call this endpoint, and for the home network also deducted from the information included in the access token.

        - The target user device is identified by the internal IP address of that device in the home network.

        - In case there is no device matching the input criteria, the operation returns a 404 error.
