Abstract
Techniques in a mobile communication device configured to operate using a wireless communication network are described. The mobile device operates to establish an emergency call with a public safety answering point entity, and subsequently monitors to receive an incoming call message which indicates whether the incoming call message is for emergency call back. If data indications in the data fields indicate that the incoming call message is for emergency call back, then the mobile device causes the emergency call back to be answered automatically.
