Abstract
Abstract Before routing an emergency call setup request signal received from a mobile subscriber toward a particular emergency service terminal, subscriber specified data associated with that particular subscriber are retrieved. By analyzing such retrieved data, the serving mobile switching center is better able to ascertain the individual need of the mobile subscriber and accordingly routes the emergency call towards the appropriate emergency service operator capable of providing effective assistance to the mobile subscriber in need.
