Abstract

A method for handling failure of a voice over 4G call connection within a wireless call connection includes the steps of detecting an indication of a failure of a voice over 4G link. An event trigger associated with the failure of the voice over 4G link is provided to a mapping database and the database maps the event trigger to at least one predetermined action responsive to indications within the mapping database. At least one predetermined action associated with the event trigger is then performed.
