More Information
Summary:A modem identifies an idle condition associated with a data network to be accessed and determines an opportunity to enter a first one of a set of low power device states based on the idle condition, where the set of low power device states further includes a second low power device state, and a host device consumes less power in the first low power device state than in the second low power device state. A notification is sent to an application processor of the host device that the modem is to enter a sleep state, where the notification identifies the first low power device state, and a low power link state is entered corresponding to the first low power device state based on a signal from the application processor. The low power link state applies to a link coupling a communications processor of the modem to the application processor.
