Abstract

Methods, systems, and devices are described for intercepting socket calls from applications installed on a mobile device while a first wireless interface is active. The first wireless interface is a cellular interface. Upon determining to release the intercepted socket calls to the socket layer, a second wireless interface is activated. The second wireless interface is a Wireless Local Area Network (WLAN) interface. The sockets calls are released to the socket layer and transmitted using the activated second wireless interface. Upon substantially completing the socket calls, the second wireless interface is deactivated. The intercepting of the socket calls and the activation of the second wireless interface occurs while the mobile device is in an idle mode.
