Abstract

A method and apparatus for enhancing the probability of a successful emergency call completion and emergency callback on a mobile station in a network, the method comprising the steps of: during an emergency call attempt, monitoring whether the mobile station has received a non-voice service request from the network and, if yes, ignoring the non-voice service request. Further, during a callback period, monitoring whether the mobile station has received a service request from the network and, if yes, ignoring the service request if the service request is a non-voice service request that is anything but a position location service request. Further, during a callback period, monitoring whether a user attempts to initiate a non-voice service request that is anything but a position location service request, and if yes ignoring the non-voice service request.
