Abstract
A component of a cellular communication system is configured to prioritize data packets based on packet tags that have been associated with the data packets. The packet tags may comprise an application identifier and a customer identifier, as examples. A Packet Data Convergence Protocol (PDCP) layer of a radio protocol stack receives a data packet and associated packet tags and assigns the data packet to a preferred transmission queue or a non-preferred transmission queue, based on the packet tags associated with the data packet. In order to manage queue overflows, data packets of the non-preferred transmission queue may be discarded when they have been queued for more than a predetermined length of time. Data packets of the preferred transmission queue, however, are retained regardless of how long they have been queued.
