Abstract

Embodiments of a system and method to identify and differentiate background traffic are generally described herein. In some embodiments, a transceiver is arranged to wirelessly transmit and receive packets over a communications network and a processor, coupled to the transceiver, is arranged to provide an indication identifying packets associated with background traffic. The indication identifying packets associated with background traffic includes a bit in a header of a packet, wherein the bit is set in a first state to indicate the packet is associated with background traffic and the bit is set in a second state to indicate the packet is associated with active traffic, or an identification of a port number and a protocol type associated with background traffic. The processor is further arranged to provide an indication for differentiating background traffic.

First claim

What is claimed is:

1. A user equipment, comprising:
a radio including a transceiver arranged to:
wirelessly transmit and receive packets to and from an eNodeB; and
execute a plurality of operation states for the transceiver, including an idle state and an active state; and

a processor, coupled to the transceiver, the processor arranged to provide, for transmission to the eNodeB, an indication identifying packets associated with background traffic for the eNodeB to hold when the radio is executing the idle state for the transceiver, and for identification of packets associated with active traffic for the eNodeB to send to the user equipment with a wake-up signal for the transceiver to transition to the active state when the radio is executing the idle state for the transceiver.

2. The user equipment of claim 1 , wherein the indication identifying packets associated with background traffic comprises a bit in a header of a packet, wherein the bit is set in a first state to indicate the packet is associated with background traffic and the bit is set in a second state to indicate the packet is associated with active traffic.

3. The user equipment of claim 2 , wherein the indication identifying packets associated with background traffic is provided by one or more applications via one or more application programming interfaces (APIs).

4. The user equipment of claim 1 , wherein the indication identifying packets associated with background traffic comprises an identification of a port number and a protocol type associated with background traffic.

5. The user equipment of claim 4 , wherein the indication identifying packets associated with background traffic is provided by one or more applications via one or more application programming interfaces (APIs).

6. The user equipment of claim 1 , wherein the processor is arranged to perform intelligent prediction of background traffic, the processor categorizing arriving packets as background packets when the radio is executing the idle state for the transceiver.

7. The user equipment of claim 1 , wherein the radio is to execute the idle state when all applications are arranged to only send background traffic, the background traffic being maintained in an uplink buffer until the radio transitions the transceiver from the idle state to the active state.

8. The user equipment of claim 1 , wherein the indication identifying packets associated with background traffic comprises a start time indicating when background traffic starts and an end time indicating when background traffic ends.

9. The user equipment of claim 1 , wherein the indication identifying packets associated with background traffic comprises an information element provided by dedicated signaling, wherein the information element includes a de-prioritization bit, the de-prioritization bit being set in a first state to signal de-prioritization of background traffic when active traffic is detected and set in a second state to signal background traffic is not to be de-prioritized.

10. The user equipment of claim 9 , wherein the information element comprises a field for setting a maximum hold time for the packets associated with background traffic.

11. The user equipment of claim 9 , wherein the information element comprises a media access control (MAC) control element (CE).

12. The user equipment of claim 9 , wherein the information element comprises a radio resource control (RRC) message.

13. A method for managing background traffic, comprising:
processing, by a processor of a user equipment, packets received and transmitted by a radio of the user equipment to and from an eNodeB;
executing one of a plurality of operation states for the user equipment, including an idle state and an active state; and
providing, by the processor of the user equipment for transmission to the eNodeB, an indication to identify packets associated with background traffic for the eNodeB to hold when the user equipment is executing the idle state, and to identify packets associated with active traffic for the eNodeB to send to the user equipment with a wake-up signal to transition to the active state when the user equipment is executing the idle state.

14. The method of claim 13 , wherein the providing an indication to identify packets associated with background traffic comprises providing a bit in a header of a packet, wherein the bit is set in a first state to indicate the packet is associated with background traffic and the bit is set in a second state to indicate the packet is associated with active traffic.

15. The method of claim 14 , wherein the providing the indication to identify packets associated with background traffic comprises providing the indication to identify packets associated with background traffic by an application through an application programming interface (API).

16. The method of claim 13 , wherein the providing the indication identifying packets associated with background traffic comprises providing an identification of a port number and a protocol type associated with background traffic.

17. The method of claim 13 , wherein the providing the indication identifying packets associated with background traffic comprises performing intelligent prediction of background traffic by categorizing arriving packets as background packets when the user equipment is executing the idle state.

18. The method of claim 13 further comprising transitioning the user equipment from the active state to the idle state when all applications are arranged to only send background traffic, the background traffic being maintained in an uplink buffer until the user equipment transitions to an active state.

19. The method of claim 13 , wherein the providing the indication identifying packets associated with background traffic comprises providing a start time indicating when background traffic starts and an end time indicating when background traffic ends.

20. The method of claim 13 , further comprising:
providing to a node an information element through dedicated signaling, wherein the information element includes a de-prioritization bit, the de-prioritization bit being set in a first state to signal de-prioritization of background traffic when active traffic is detected and set in a second state to signal background traffic is not to be de-prioritized.

21. An enhanced base station (eNodeB), comprising:
a buffer for maintaining packets received from a user equipment (UE) prior to processing and for maintaining packets for transmission to the UE; and
a processor, coupled to the buffer, the processor arranged to receive an indication from the UE identifying packets associated with background traffic for applications executed via the UE, the processor to process packets according to the received indication, including, when the UE is executing an idle state:
holding the packets associated with background traffic from transmission to the UE; and
transmitting packets associated with active traffic to the UE and a wake-up signal for the UE to transition from the idle state to an active state.

22. The eNodeB of claim 21 , wherein the indication identifying packets associated with background traffic comprises instructions for setting a bit in a header of a packet, wherein the bit is set in a first state to indicate the packet is associated with background traffic and the bit is set in a second state to indicate the packet is associated with active traffic.

23. The eNodeB of claim 21 , wherein the ind
