Dynamic adjustment of keep-alive messages for efficient battery usage in a mobile network

摘要

Systems and methods for dynamic adjustment of keep-alive message intervals in a mobile network are disclosed. One embodiment of maintaining an IP connection between a mobile terminal and a network node over a network includes, detecting a rate with which the client-slide request are made from the mobile terminal, detecting a rate with which the client-slide request are made from the mobile terminal, sending, by the network node, keep-alive messages to the mobile terminal in an absence of network traffic through the IP connection between the mobile terminal and the network node, and/or further optimizing the time intervals between the keep-alive messages based on a cost to send the keep-alive messages in the network.

1. A method of maintaining communication between a mobile terminal and a network node over a network, the method comprising:
detecting a rate with which requests are made to or from the mobile terminal; dynamically adjusting time intervals between the keep-alive messages sent to or from the mobile terminal based on the rate with which the requests are made; sending, keep-alive messages to or from the mobile terminal in an absence of network traffic between the mobile terminal and the network node; monitoring the lengths of several periods of communication inactivity between the mobile terminal and the network node; determining a maximum interval between keep-alive messages based on the several monitored lengths of periods of inactivity such that the maximum interval meets a criterion of statistical confidence; and setting at least one interval between keep-alive messages to the maximum determined interval.
