9. A method for operating a policy control entity of a cellular network, wherein a data packet flow is transmitted from an application entity through a cellular network to a user equipment, the method comprising:
receiving a policy request from a user plane entity handling the data packet flow in the cellular network, the policy request comprising a flow identifier allowing an identification of the data packet flow in the cellular network, and policy information indicating a policy to be applied to the data packet flow in the cellular network for a transmission of the data packet flow through the cellular network;
determining that the policy as received in the policy request is allowed; and
transmitting an answer to the policy request to the user plane entity indicating that the policy is allowed; and
wherein before the policy request is received, a query message is received from a subscriber database including an indication to activate an exposure operating mode in which a content provider operating the application entity informs the cellular network about the policy to be applied to the data packet flow in the cellular network.
