Abstract
A example method includes receiving, at a cell broadcast center (CBC) an alert request providing information for distribution to at least one user equipment, identifying a broadcast area based on the alert request, one or more cells within the broadcast area, determining a warning area list (WAL) for a message and transmitting the message with the WAL. The WAL may be a list of one or more Tracking Area Identity (TAIs) or a list of cell identifiers depending on various conditions.
