A method for controlling data transmission within a telecommunications network involves providing interconnections to both a core network and to at least one user device via a base station. A configurable network is defined interconnecting the at least one core network and the base station. A first network slice is selected responsive to use of the configurable network by a first application. A second network slice is selected responsive to use of the configurable network by a second application. Data transmission are provided between the core network and the base station over the configurable network based on the selected first or second network slice.
