A data communication system is disclosed, comprising a network provided with a control server for managing network resources, and a delivery server for delivering multimedia content to one or more UE (user equipment) devices, wherein the control server is arranged to pass a network session ID, of a network session between the delivery server and the UE device, to the delivery server, and the delivery server is arranged to keep track of the network session independently of the control server, such that once the network session ID of the network session has been passed to the delivery server, the control server keeps no reference to the network session and takes no part therein.
