1. A method of assessing a risk to a user in engaging in a communications session on a mobile communications device, the method comprising:

  • collecting, on a mobile communications device, a first set of sensor data, the first set of sensor data including data reflective of at least a geographic location of the mobile communications device and a degree of motion of the mobile communications device;

    implementing a state machine on the mobile communications device, wherein the state machine includes a first state that indicates to an in-transit highway context and a second state that indicates to an in-transit city context;

    determining a first context of the mobile communications device, the first context reflecting a degree of user risk associated with using the mobile communications device to engage in a communications session, wherein determining the first context comprises analyzing said first set of sensor data on the mobile communications device, wherein the first context corresponds to at least one of the first state or second state;

    recording said first context in a memory of the mobile communications device;

    collecting a second set of sensor data on the mobile communications device, said second set of sensor data including data reflective of at least a geographic location of the mobile communications device and a degree of motion of the mobile communications device;

    determining an updated context of the mobile communications device, the updated context reflecting a degree of user risk associated with using the mobile communications device to engage in a communications session, wherein determining the updated context comprises analyzing the second set of sensor data on the mobile communications device, wherein the updated context corresponds to at least one of the first state or the second state; and

    transmitting a context-change notification message from the mobile communications device to enable a remote call processing entity to monitor the context of the mobile communications device, wherein sending the context-change notification message occurs only if the updated context of the mobile communications device and the first context of the mobile communications device are different contexts, and wherein management by the remote call processing entity of incoming requests for communication to the mobile communications device, outgoing requests for communication from the mobile communications device, or ongoing communications including the mobile communication device is defined in terms of the context-change notification message;

    wherein the method is performed by the mobile communications device while no user communication session on the mobile communications device is pending or in progress, such that the remote call processing entity is capable of having a priori knowledge of the context of the mobile communications device when incoming call requests to the mobile communications device are received, and such that the remote call processing entity may process an incoming call request based on the received context-change notification message without further communicating with the mobile communications device to determine a current mobile communications device context.
