1. A communications network comprising:

  • multiple base stations, each capable of communicating wirelessly with one or more wireless terminals; and

    a network core communicatively coupled to the base stations, the network core comprising;

    a data cache to which base stations can write data received from terminals, the data cache being accessible from outside the network core in such a way that users external to the network core can write data to the data cache at times that are not scheduled by the network core; and

    a network controller capable of controlling the operation of the base stations, the network controller being configured to schedule a propagation to the terminals of data stored in the data cache by allocating base station transmission bandwidth for the transmission of the data to one or more of the terminals, the network controller being further configured to allocate the transmission bandwidth in dependence on a loading associated with the base station to which the one or more terminals are attached relative to a loading associated with others of the multiple base stations.
