Abstract
Methods and apparatuses enable maintaining wireless connectivity while the wireless client device is in a power save mode. The system includes a host operating system (OS) that handles wireless connections while the device is executing in normal operation, and an embedded agent that handles the wireless connections when the device switches to power saving operation and the host OS switches to a sleep or standby state. The system detects a change in the power save mode and triggers an exchange of session context information between the host OS and the embedded agent (from the host OS to the embedded agent when the system enters the power save mode, and from the embedded agent to the host OS when the system returns to normal operation from the power save mode). The system also triggers the switching of management consistent with the passing of session context information.
