Figure 9: Token authorization

The message signaling that takes place in the session initialization protocol is needed to complete the Remote Assistance session; that is, to change the state from the basic Remote Assistance connection state in which the expert does not have the view of the novice screen, to the state in which the expert has the view of the novice screen.

When the Remote Assistance connection has completed successfully, or if there was an error during connection, the novice is responsible for keeping track of this state change.
