DETECTION AND REPORTING OF KEEPALIVE MESSAGES FOR OPTIMIZATION OF KEEPALIVE TRAFFIC IN A MOBILE NETWORK
First Claim
1. A method of identifying keepalives from a Transport Control Protocol (TCP) stream, comprising:
- examining patterns of data sent from and received by a mobile application on a mobile device, wherein the patterns have variable intervals and sizes;
performing statistical analyses on the patterns of data sent from and received by the mobile application to detect a pattern that is regular and to detect regular byte sizes; and
identifying the keepalives from the TCP stream occurring over the same TCP session based on information relating to the pattern that is detected as regular and the regular byte sizes.

Abstract
Detection of network transactions or keepalives for maintaining long lived connections are disclosed. A keepalive detector can detect keepalive traffic based on keepalive parameters determined from an analysis of socket level network communication log data that record data transfer events including data sent from mobile applications or clients on a mobile device and data received by the mobile applications or clients on the mobile device, timing characteristics, protocol types, etc. Various statistical analyses can be performed on the network communication data to detect keepalives, taking into account variability in intervals of the data transfer events and sizes of data sent and received on each event. The keepalive detector can also detect keepalives from stream data on a mobile device by analyzing socket level communication messages including timing characteristics and amount of data transferred to detect keepalives and report keepalives using a data structure.

8. A mobile device, comprising:
-
a memory; a processor disposed in communication with the memory and configured to execute a plurality of instructions stored in the memory to; examine data transfer events, each data transfer event characterized by data sent from and received by a mobile application on a mobile device, wherein the data transfer events occur at variable intervals and have variable sizes; perform statistical analyses on the data transfer events to detect a data transfer event that is regular and to detect regular byte sizes; and identify network transactions from a Transport Control Protocol (TCP) stream occurring over the same TCP session based on information relating to the data transfer event that is detected as regular and the regular byte sizes. - View Dependent Claims (9, 10, 11)

18. A method of detecting keepalives from stream data on a mobile device, comprising:
-
detecting a message including stream data for a socket; based on information in the message, determining whether to create or update a connection object, the connection object associated with a data structure including an identifier for the connection object and time the socket was created; evaluating the connection object to determine whether a keepalive is detected, the data structure further including a flag for indicating whether the keepalive was detected. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
