Packet classification and prioritization using a UDP checksum in a mobile wireless device

A wireless apparatus including

• an application processor configured for
• generating a higher layer packet,
• setting a value of a header field in the higher layer packet, wherein the higher layer packet is a user datagram protocol packet, and the header field is a checksum field in a header of the user datagram protocol packet, and
• transferring the higher layer packet to a transceiver;
• and
• the transceiver configured for
• receiving the higher layer packet from the application processor,
• reading the value of the header field in the higher layer packet,
• clearing the value of the header field in the higher layer packet,
• creating at least one lower layer protocol data unit from the higher layer packet, and
• mapping the lower layer protocol data unit to a wireless access channel having a link layer transmission property based on the header field value read by the transceiver, wherein the wireless access channel is one of a plurality of wireless channels, each associated with a different quality of service (QoS) configuration, and
• wherein the application processor and the transceiver are physically integrated within the wires apparatus.

A non-transitory computer readable medium storing instructions, which when executed by a processor, cause the processor to perform a method for packet classification in a mobile device having an application processor and a transceiver integrated therein, the method comprising:

• forming by the application processor a packet containing a segment specifying a quality of service property for the packet, the segment comprising a header field of a higher layer packet, wherein the packet is a user datagram protocol packet, and the field is a checksum field in a header of the user datagram protocol packet;
• reading by the transceiver a value of the segment;
• clearing by the transceiver the value of the segment;
• creating by the transceiver at least one protocol data unit from the packet;
• establishing by the transceiver a wireless access channel having one or more transmission properties based on the value of the segment;
• and
• mapping by the transceiver the at least one protocol data unit to the established wireless access channel.
