Abstract
A method and apparatus for packet classification and prioritization using a user datagram protocol (UDP) header in a mobile wireless device. The mobile wireless device includes an application processor and a transceiver. The application processor sets a value of a field embedded in a higher layer packet and transfers the higher layer packet to the transceiver. The transceiver receives the higher layer packet from the application processor and reads the set value of the embedded field. The transceiver clears the value in the embedded field and creates at least one lower layer protocol data unit from the higher layer packet. The transceiver maps the lower layer protocol data unit to a wireless access channel having a transmission property based on the read value of the embedded field. In representative embodiments, the embedded field is an optional checksum in a UDP header.
