Abstract
A method and cell broadcast center (CBC) system are described for issuing an emergency alert message containing at least one hyperlink corresponding to content stored on a web server. The operations performed by the CBC include receiving an emergency alert message. The emergency alert message includes a hyperlink to web content. The CBC processes the emergency alert message by: issuing a request to a web server for a content corresponding to the hyperlink, and issuing an emergency broadcast request to carrier networks. The emergency broadcast request includes both: the emergency alert message, and the content corresponding to the hyperlink. The issuing the emergency broadcast request, causes delivery of the content corresponding to the hyperlink to a browser cache on a user equipment without user selection of the hyperlink on the user equipment.
