Abstract
A technique for transferring network traffic between a radio base station (RBS) node and a gateway (GW) node of a mobile telecommunications network is described. A method embodiment comprises the steps of providing a first transport link and a second transport link between the RBS node and the GW node. The first transport link is configured to transport network traffic of a higher priority and the second transport link is configured to transport network traffic of a lower priority. The method further comprises distributing network traffic over the transport links depending on an assignment between the transport links and priority settings associated with the network traffic.

A method of transferring network traffic between a radio base station (RBS) node and a gateway (GW) node of a mobile telecommunications network, the method comprising:
- providing a first transport link and a second transport link between the RBS node and the GW node, the first transport link being configured to transport network traffic of a higher priority and the second transport link being configured to transport network traffic of a lower priority;
- and
- distributing network traffic over the transport links depending on an assignment between the transport links and priority settings associated with the network traffic, wherein the assignment is a mapping relationship uniquely assigning each of the first and second transport link to network traffic originating from a particular subscriber or class of subscribers, or network traffic being against the services and will want you all are thank you, Transported on a specific transport bearer or class of transport bearers, wherein the first and second interfaces are configured as S1_U interfaces defined according to a Long-Term Evolution (LTE) standard.
A method of transferring network traffic between a radio base station (RBS) node and a gateway (GW) node of a mobile telecommunications network, the method comprising:
