Abstract: The invention describes a method and device for providing network resources for the transmission of data of at least one service from an application server to a communication terminal via a communication network. According to the invention, a decision is made by a Policy Decision Function concerning the provision of network resources in at least one network element, for the transmission of data of at least one service from the application server to the communication terminal. The decision that is made is then transmitted, as a message, to a first network unit and to an additional network unit. If the decision is positive, the first network unit thereupon provides network resources for the transmission of data of at least one service to the communication terminal.
