Abstract

A method for requesting and providing on-demand priority to internet protocol (IP) flows is disclosed. A request to invoke transmission priority is received. Whether to mark a priority invocation packet for an IP flow with a priority Differentiated Services Code Point (DSCP) marking is determined The priority invocation packet is marked based on the determination and sent. A priority invocation packet for an IP flow that has a priority DSCP marking is received from a wireless device. The priority invocation packet is sent to its destination. Transmission priority is provided to IP flows received from the wireless device or sent to the wireless device for a period of time or until an indication of failed authorization is received.

3. The method of claim 1, wherein the determining comprises determining to mark priority invocation packets for all internet protocol (IP) flows.

4. The method of claim 1, wherein the determining comprises determining to mark priority invocation packets for only internet browser-generated internet protocol (IP) flows.

5. The method of claim 4, wherein the determining further comprises determining to mark priority invocation packets for only internet protocol (IP) flows directed to certain universal resource locator(s) (URL(s)).

6. The method of claim 1, further comprising sending more packets for the internet protocol (IP) flow that are not marked with a priority Differentiated Services Code Point (DSCP) marking.

7. An apparatus for requesting on-demand priority for internet protocol (IP) flows, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to;

receive a request to invoke transmission priority;

determine whether to mark a priority invocation packet for an IP flow with a priority Differentiated Services Code Point (DSCP) marking;

mark the priority invocation packet based on the determination; and

send the outgoing packet.

11. The apparatus of claim 10, wherein the instructions executable to determine comprise instructions executable to determine to mark priority invocation packets for only internet protocol (IP) flows directed to certain universal resource locator(s) (URL(s)).

12. The apparatus of claim 7, further comprising instructions executable to send more packets for the internet protocol (IP) flow that are not marked with a priority Differentiated Services Code Point (DSCP) marking.

13. An apparatus for requesting on-demand priority for internet protocol (IP) flows, comprising:

means for receiving a request to invoke transmission priority;

means for determining whether to mark a priority invocation packet for an IP flow with a priority Differentiated Services Code Point (DSCP) marking;

means for marking the priority invocation packet based on the determination; and

means for sending the outgoing packet.

14. The apparatus of claim 13, wherein the means for determining comprises means for determining to mark priority invocation packets for all internet protocol (IP) flows.

15. The apparatus of claim 13, wherein the means for determining comprises means for determining to mark priority invocation packets for only internet browser-generated internet protocol (IP) flows.

16. The apparatus of claim 15, wherein the means for determining further comprises means for determining to mark priority invocation packets for only internet protocol (IP) flows directed to certain universal resource locator(s) (URL(s)).

17. A computer-program product for requesting on-demand priority for internet protocol (IP) flows, the computer-program product comprising a computer-readable medium having instructions thereon, the instructions comprising:

code for receiving a request to invoke transmission priority;

code for determining whether to mark a priority invocation packet for an IP flow with a priority Differentiated Services Code Point (DSCP) marking;

code for marking the priority invocation packet based on the determination; and

code for sending the outgoing packet.

18. The computer-program product of claim 17, wherein the code for determining comprises code for determining to mark priority invocation packets for all internet protocol (IP) flows.

19. The computer-program product of claim 17, wherein the code for determining comprises code for determining to mark priority invocation packets for only internet browser-generated internet protocol (IP) flows.

20. The computer-program product of claim 17, wherein the code for determining further comprises code for determining to mark priority invocation packets for only internet protocol (IP) flows directed to certain universal resource locator(s) (URL(s)).

21. A method for providing on-demand priority to internet protocol (IP) flows, comprising:

receiving from a wireless device a priority invocation packet for an IP flow that has a priority Differentiated Services Code Point (DSCP) marking;

sending the priority invocation packet to its destination; and

providing transmission priority to subsequent packets in all IP flows received from the wireless device or sent to the wireless device for a period of time or until an indication of failed authorization is received.

22. The method of claim 21, wherein the providing priority comprises arranging the packets in relation to other packets so that the packets have a lower probability of being blocked than the other packets.

23. The method of claim 21, further comprising contacting an authorization server to determine if the internet protocol (IP) flow is authorized based on subscription data about the wireless device.
