The invention relates to methods for providing a network element of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller via an interface to the network element. In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller to add control parameters to control messages transmitted from the controller to a network element via the interface.
