3.1.7 Other Local Events
If the RTSP connection receives a teardown message as it does in standard Miracast, or if the connection to the Source is lost, or if the TCP port 7250 connection is lost, the Sink MUST close its session.
If any global configuration from section 3.1.1 is changed, then the new configuration MUST apply to all future connections and the initialization step MUST be repeated. Any existing connections SHOULD be terminated but an implementation MAY leave the sessions connected.
