Abstract

Systems and methods for recognizing congestion in a mobile network to make intelligent decisions regarding connecting to an operator network is disclosed. A mobile device having a local proxy equipped with congestion recognition capabilities can use time elapsed to establish connection with a mobile base station in the mobile network to recognize congestion at the mobile base station. Further, in response to recognizing congestion at the mobile base station, the local proxy can selectively block traffic from the mobile device from traversing the mobile network to reduce signaling overload on the mobile network.

Claims

1. A system comprising a mobile client implemented on a mobile device for reducing signaling overload on a mobile network, the mobile client comprising:

one or more processors;

one or more memories including program instructions, when executed are configured for;

detecting an increase in setup times for connection requests in a mobile network from a baseline based on a first timestamp and a second timestamp;

recognizing congestion at a mobile base station in the mobile network based at least in part on the increase in setup times, wherein, the congestion is recognized by the mobile client before a rejection to a connection request is received from the mobile base station; and

applying a blocking policy to selectively block traffic from the mobile device from reaching the mobile network in response to recognizing and confirming that the mobile network is congested, wherein confirming that the mobile network is congested comprises;

determining a signal strength range from at least one of a cell identifier and a location area code;

comparing a received signal strength to the signal strength range; and

determining the increase in setup times is not due to a low signal strength, wherein the mobile client uses the first timestamp and the second timestamp to determine a time elapsed to establish a connection with the mobile base station in the mobile network.

2. The system of claim 1, wherein the mobile client logs the setup times elapsed to periodically inform a service provider associated with the mobile network regarding the congestion at the mobile base station.

3. The system of claim 1, wherein the congestion is recognized by the mobile client residing on the mobile device, independent of other mobile clients residing on other mobile devices on the mobile network.

4. The system of claim 1, wherein the congestion is recognized by the mobile client without incurring signaling load on the mobile network.

5. The system of claim 1, wherein the congestion is recognized by the mobile client before a rejection to a connection request is received from the mobile base station.

6. The system of claim 1, wherein the mobile client is further configured to provide selective blocking of the traffic from the mobile device based on time criticality of transactions.

7. The system of claim 6, wherein a time critical transaction includes a transaction resulting from a user-initiated request.

8. The system of claim 6, wherein the selective blocking of the traffic is in effect until an end of a predefined time period or when a time critical transaction is received.

9. The system of claim 1, wherein the mobile client recognizes congestion at the mobile base station without requiring mobile network infrastructure support.

10. The system of claim 1, wherein the mobile client recognizes congestion at the mobile base station without relying on a specific mobile device chipset or baseband.

11. The system of claim 1, wherein the mobile client queries a modem on the mobile device for signal strength and base station information to validate congestion at the mobile base station.

12. The system of claim 1, wherein the mobile client uses application behavior to categorize application traffic and selectively blocks certain types of application traffic from traversing the mobile network to reduce signaling overload on the mobile network.

13. The system of claim 1, wherein the mobile base station is a Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) mobile network, a Node B in a 3G mobile network or an Evolved Node B in Long-Term Evolution (LTE) network.

14. The system of claim 1, wherein the first timestamp is a connection request timestamp generated by the mobile device, and the second timestamp is a connection established timestamp generated by the mobile base station.

15. A non-transitory machine readable storage medium having stored thereon instructions which when executed by a machine, causes the machine to:

detect an increase in setup times for connection requests in a mobile network from a baseline based on a first timestamp and a second timestamp;

recognize congestion at a mobile base station in the mobile network based at least in part on the increase in setup times, wherein, the congestion is recognized by a mobile client before a rejection to a connection request is received from the mobile base station; and

apply a blocking policy to selectively block traffic from a mobile device from reaching the mobile network in response to recognizing and confirming that the mobile network is congested, wherein confirming that the mobile network is congested comprises;

determining a signal strength range from at least one of a cell identifier and a location area code;

comparing a received signal strength to the signal strength range; and

determining the increase in setup times is not due to a low signal strength.

16. The non-transitory machine readable storage medium of claim 15, wherein the first timestamp is a connection request timestamp generated by the mobile device, and the second timestamp is a connection established timestamp generated by the mobile base station.
