Abstract: Systems and methods are provided enabling context information, such as a current speed of travel, to be transmitted between a context source, such as a vehicle, and a mobile device. Illustratively, the mobile device may be configured to utilize context information to enforce context-based restrictions on the mobile device, such as to restrict non-emergency functionality of the device when travelling above a threshold speed. Specifically, embodiments of the present application enable context information to be encoded within service data, and transmitted to the mobile device without requiring an established connection (e.g., a “pairing”) between the mobile device and the context source. For example, specific context information may be encoded into a service identifier, and transmitted within a service record to the mobile device. The mobile device may then decode the context information from the service identifier to determine a context, e.g., for use in context-based policy enforcement.
