Method and apparatus for use of alert type to choose cell-site-selection process for selecting cell sites to broadcast alert

Disclosed herein is a mechanism for dynamically varying the process of selecting cell sites to broadcast an alert message. The mechanism involves using the type or other characteristic of the alert message as a basis to choose a particular cell-site selection process or level of precision for defining cell site coverage. For example, given one type of alert message, a particular cell-site selection process and/or level of precision may be used to determine the cell sites in the target area, and given another type of alert message, a different cell-site selection process and/or level of precision may be used to determine the cell sites in the target area.
