Abstract

A mobile device that incorporates the subject disclosure may perform, for example, obtaining performance characteristics for network segments of a network where the network segments are selected from a group of network segments of the network based on a trajectory of the mobile device. The mobile device can monitor power state transitions of the mobile device, and can predict a future power state of the mobile device based on the monitoring of the power state transitions. The mobile device can determine a target time for sending a request for transmission of a data packet over the network where the target time is determined based on the performance characteristics for the network segments and based on the future power state of the mobile device. The mobile device can schedule a time for sending the request for transmission according to the target time. Other embodiments are disclosed.
