Abstract
A telecommunications system and method is disclosed for providing a battery status indicator associated with a calling mobile station (MS) during an emergency call setup. The battery status indicator is transmitted to the emergency center as a new parameter or as a modified existing parameter, such as cell ID. The emergency center can provide special handling for such calls, such as displaying the low battery indicator to the emergency operator. In addition, the cellular network serving the MS can handover the call to a cell with lower power demands in order to prolong the battery life.
