Systems and method for communicating priority information for use in scheduling the transmission of data

摘要

In one aspect, the invention provides apparatuses and methods for communicating, from one network node to another network node, application data together with priority information so that the receiving network node may use the priority information in scheduling the transmission of the application data to the intended receiver of the application data.

1. A method, performed by a first network node, for communicating to a second network node priority information that can be used by the second network node to schedule the transmission of downlink application data to a user equipment (UE), comprising:
(a) receiving, at the first network node via a network, a first packet transmitted from a device connected to the network, the first packet containing downlink application data (AD1) intended for the UE; (b) determining the priority of said downlink application data intended for the UE; (c) creating a second packet comprising a header and payload, the payload of the second packet comprising at least some of the downlink application data; and (d) transmitting, from the first network node, the second packet towards the second network node, wherein the step of creating the second packet comprises including in the header of the second packet priority information identifying the priority determined in step (b), and the step of transmitting the second packet comprises transmitting the second packet towards the second network node with at least some of the downlink application data and the priority information.
