A system and method are disclosed for offloading control of services in a mobile device to a non-cellular wireless network, such as Wi-Fi. The described system and method allow the overall connection management to be performed by an application processor, while services are handled in a modem using Wi-Fi connectivity. The Wi-Fi subsystem can be fully driven by the modem for time critical operations allowing the application processor to be off (or in low-power mode) when it is not involved in the delivery of services. Battery power is saved by being able to substantially power down the application processor.
