A system configured to deliver a first data traffic that shall be treated with priority from a first Internet content provider to a mobile user equipment via an access network of a mobile communications network, the system comprising: - a gateway connected to a controller and adapted to receive the first data traffic from the controller and to transmit the first data traffic to the mobile user equipment, wherein the gateway is adapted to receive a second data traffic from a server of a second Internet content provider and to transmit the second data traffic to the mobile user equipment, wherein the first and second data traffic are transmitted to the mobile user equipment through the gateway, - a content delivery entity, the content delivery entity comprising: - an interface to a server of the first Internet content provider, the interface being configured to detect the first data traffic that shall be treated with priority, - an acceleration unit comprising a content data network edge server and a content data network cache server, the acceleration unit being configured to accelerate the delivery of the first data traffic from the first Internet content provider to the content delivery entity, - the controller configured to control a specified fraction of a data traffic capacity of the gateway for the first data traffic and configured to forward the first data traffic to the gateway and to request a policy controller of the mobile communications network to increase a priority of a default bearer used to carry the first data traffic in the access network of the mobile communications network or set up a dedicated bearer used to carry the first data traffic in the access network, wherein the second data is routed from the second Internet content provider (330, 390) through the access network and the first traffic is delivered faster than the second traffic, wherein the controller is configured in such a way that it forwards the first data traffic from the first Internet content provider through the controller to the gateway. -
