Abstract
A system and method is provided for a communications device to conditionally attempt an emergency call setup. The communications device maintains at least one condition for attempting emergency call setups. Upon receiving a message prompting an emergency call setup, the communications device attempts the emergency call setup only if any of the at least one condition is satisfied. The at least one least condition is defined such that the communications device does not erroneously attempt to establish an emergency call when there is no emergency. The at least one condition might for example include whether the message prompting the emergency call setup indicates a message source that is trusted by the user of the mobile device. A system and method is also provided for a communications network to block at least at least some of the messages from being delivered to their target communications device.
