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 for reducing signaling overload on a mobile network, comprising:

a mobile client residing on a mobile device,

wherein the mobile client uses time elapsed to establish connection with a mobile base station in the mobile network to recognize congestion at the mobile base station, and in response to recognizing congestion at the mobile base station, selectively blocks traffic from the mobile device from traversing the mobile network to reduce signaling overload on the mobile network.

2. The system of claim 1, wherein the mobile client logs the time 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 selectively blocks 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 1, wherein the selective blocking is in effect until the 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 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. A machine readable storage medium having stored thereon instructions which when executed by a machine, causes the machine to:

detect increase in setup times for connection requests in a mobile network from a baseline;

detect congestion at one or more base stations in the mobile network based at least in part on the detected increase in setup times, wherein, the congestion is detected by the mobile client before a rejection to a connection request is received from one of the base stations.

15. The medium of claim 14, wherein the machine applies a blocking policy to selectively block traffic from a mobile device from reaching the mobile network in response to detecting and confirming that the mobile network is congested.
