First Claim
1. A method of enhancing the probability of a successful emergency call completion on a mobile station in a network, comprising:
- during an emergency call attempt by a mobile station, determining whether the mobile station is engaged in one or more data communication sessions with the network;
if the mobile station is engaged in one or more data communication sessions;
terminating the one or more data communication sessions;
attempting to acquire a network of the one or more data communication sessions for the emergency voice call;
if the attempting to acquire the network of the one or more data communication sessions failed, attempting to acquire a different network for the emergency call;

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.
