A resource manager (600) determines occupation information concerning how much of the previously allocated capacity is occupied by previously authorized video streams is determined before authorizing transmitting a new requested video stream. By checking there is sufficient core network capacity, a risk of disrupting existing video streams or causing other problems by overloading the allocated capacity, is reduced or avoided. Thus less capacity in the core network is needed, and so costs of such capacity can be reduced and there is increased confidence that demand peaks will be handled more gracefully. By checking without obtaining occupation information from the core network, the system can be more independent of the core network, to reduce costs of a real time interface to the core network.
