Abstract

Delivery of delay-tolerant data according to a predicted mobility of a user device in a network-controlled client cache architecture. A network node receives information about a predicted mobility of a user device, and monitors a network status of radio access nodes of a communication network, based on the received information about predicted mobility. Based on the monitored network status, the network node determines when, and via which radio access node, to transfer the requested data. A user device can send information about a predicted mobility of the user devices, together with information about data being requested, and receive information about when to initiate a transfer of the requested data, based on the predicted mobility of the user device. A better utilization of radio resources can be obtained.
