Method, apparatus and computer program for providing a data object from a content server to a client device over a radio access network (RAN)

A node for transferring a plurality of data objects associated with an HTTP request to a client device in a communications network, the node comprising:

• a processor;
• and
• a memory comprising a computer program which when executed by the processor causes the node to:
• receive, from a content server, the plurality of data objects associated with the HTTP request;
• identify one or more properties of the plurality of data objects associated with the HTTP request to be delivered to the client;
• obtain content transfer optimization information based on one or more properties of a radio access network (RAN) and a Content Server, client device instructions, and the one or more properties of the plurality of data objects;
• when the content transfer optimization information indicates that optimization is required for one or more of the plurality of data objects, assign a priority to each of the plurality of data objects;
• when the properties of the RAN indicate congestion not exceeding a predetermined threshold, transfer the plurality of data objects in order of priority;
• and
• when the properties of the RAN indicate congestion exceeding a predetermined threshold, modify one or more of the plurality of data objects by re-encoding the one or more of the plurality of data objects or replacing the one or more of the plurality of data objects with a different data object type, and transfer the modified plurality of data objects in order of priority.
