Abstract

The disclosed technology includes methods, systems, and computer readable media for optimizing network traffic management in a mobile network. One method includes determining, by a network optimization client of a mobile device, a packet call quality (PCQ) associated with transmission of packets between the mobile device and a mobile communications network. The PCQ includes a numerical indication of call quality. A congestion recognition (CR) module of the mobile device determines a measure of user congestion based on the PCQ that indicates a total delay experienced by a user of the mobile device during the transmission of packets.

Claims

1. A method comprising:

at a mobile device;

determining a packet call quality (PCQ) associated with transmission of packets between the mobile device and a mobile communications network, the PCQ including a numerical indication of call quality,

wherein the PCQ is based, in part, on a maximum, a minimum, or an average amount of time a user has waited to get packet access while the mobile device'"'"'s screen is in an active state;

determining a measure of congestion based on the PCQ that indicates a total delay experienced by a user of the mobile device during the transmission of packets; and

applying a blocking policy to block outgoing packets from being transmitted from the mobile device when the measure of congestion is above a threshold.

2. The method of claim 1, wherein the blocking policy includes at least one of:

delaying transmission of packets from the mobile device until a later time, and responding to client requests from a local cache instead of from a remote source.

3. The method of claim 1, wherein determining the PCQ and the measure of congestion are performed independent of other mobile devices and without communicating with a server-side network optimization component.

4. The method of claim 1, wherein determining the PCQ includes measuring the delay caused only by poor packet access provided by a network operator.

5. The method of claim 1, wherein determining the measure of congestion is based, in part, on a PCQ breakdown for individual connections and each delay cause.

6. The method of claim 1, wherein the PCQ is further based, in part, on a maximum, a minimum, or an average amount of time a background service has waited to get packet access while the mobile device'"'"'s screen is in an inactive state.

7. The method of claim 1, further comprising providing a daily graph showing hourly PCQ.

8. The method of claim 1, wherein the blocking policy is adjusted to prevent the mobile device from connecting to or attempting to connect to a network based on whether the mobile device is stationary or in motion.

9. The method of claim 1, wherein the blocking policy is optimized to reduce congestion of the mobile device based on one or more of the following factors:

the geographical location of cellular towers, the number or density of cellular towers, the congestion of cellular towers relative to a rate at which the mobile device is moving, and the cellular tower the mobile device is connected to.

10. A mobile device, comprising:

a memory;

a screen; and

a processor, wherein the processor is configured to;

determine a packet call quality (PCQ) associated with transmission of packets between the mobile device and a mobile communications network, the PCQ including a numerical indication of call quality,

wherein the PCQ is based, in part, on a maximum, a minimum, or an average amount of time a user has waited to get packet access while the mobile device'"'"'s screen is in an active state;

determine a measure of congestion based on the PCQ that indicates a total delay experienced by a user of the mobile device during the transmission of packets; and

apply a blocking policy to block outgoing packets from being transmitted from the mobile device when the measure of congestion is above a threshold.

11. The mobile device of claim 10, wherein the processor applies the blocking policy by delaying transmission of packets from the mobile device until a later time, and responding to client requests from a local cache instead of from a remote source.

12. The mobile device of claim 10, wherein the processor determines the PCQ and the measure of congestion independent of other mobile devices and without communicating with a server-side network optimization component.

13. The mobile device of claim 10, wherein the processor determines the PCQ by measuring the delay caused only by poor packet access provided by a network operator.

14. The mobile device of claim 10, wherein the processor determines the measure of congestion based, in part, on a PCQ breakdown for individual connections and each delay cause.

15. The mobile device of claim 10, wherein the processor determines the PCQ based, in part, on a maximum, a minimum, or an average amount of time a background service has waited to get packet access while the mobile device'"'"'s screen is in an inactive state.

16. The mobile device of claim 10, wherein the processor adjusts the blocking policy to prevent the mobile device from connecting to or attempting to connect to a network based on whether the mobile device is stationary or in motion.

17. The mobile device of claim 10, wherein the processor is further configured to optimize the blocking policy to reduce the congestion based on one or more of the following factors:

the geographical location of cellular towers, the number or density of cellular towers, the congestion of cellular towers relative to a rate at which the mobile device is moving, and the cellular tower the mobile device is connected to.

18. A non-transitory computer-readable storage medium storing instructions to be implemented by a mobile device having a processor, wherein the instructions, when executed by the processor, cause the mobile device to:

determine a packet call quality (PCQ) associated with transmission of packets between the mobile device and a mobile communications network, the PCQ including a numerical indication of call quality,

wherein the PCQ is based, in part, on a maximum, a minimum, or an average amount of time a user has waited to get packet access while the mobile device'"'"'s screen is in an active state;

determine a measure of congestion based on the PCQ that indicates a total delay experienced by a user of the mobile device during the transmission of packets; and

apply a blocking policy to block outgoing packets from being transmitted from the mobile device when the measure of congestion is above a threshold.

19. The non-transitory computer-readable storage medium of claim 18, wherein the blocking policy includes at least one of:

delaying transmission of packets from the mobile device until a later time, and responding to client requests from a local cache instead of from a remote source.

20. The non-transitory computer-readable storage medium of claim 18, wherein the instructions further cause the mobile device to determine the PCQ and the measure of congestion independent of other mobile devices and without communicating with a server-side network optimization component.
