Proximity-based session handovers are performed between devices of the software platform utilizing short range signals. The short range signals include a frequency signature. The frequency signature is associated with a vehicle. A handover a session in progress from a mobile device to the vehicle is performed based on the detection of a short range signal. ## Claims ### Claim 1 A method comprising: detecting a short range signal at a mobile device, wherein the short range signal includes a frequency signature of an infotainment device integrated with a vehicle comprising an in-vehicle internet source;
