Abstract

Embodiments are directed to determining whether one or more physical user interactions are present, at a wireless communication device, that indicate a near-future potential communication session resource request. Before the determination, a communication interface of the device is in a dormant state characterized by the device not being permitted to engage in a communication session with a wireless communication network. The device transitions the communication interface, after the determination, from the dormant state to an active state. In the active state, the device performs one or more actions to reduce a delay associated with a transmission of the potential communication session resource request in the event that the potential communication session resource request is actually transmitted by the device. For example, in the active state, the device can power-up or wake-up a radio bearer or modem to reduce a delay before transmission of the potential communication session resource request.
