Delivering wireless emergency alerts containing hyperlinks to mobile wireless devices via mobile wireless broadcast channels
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.
1. A method for issuing, by a cell broadcast center, an emergency alert message containing at least one hyperlink corresponding to content stored on a web server, the method comprising:
receiving an emergency alert message at the cell broadcast center issued by an emergency alert system, wherein the emergency alert message includes a hyperlink to web content; and
processing 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 including both:
the emergency alert message, and
the content corresponding to the hyperlink,
wherein the issuing the emergency broadcast request, causes a delivery of the content corresponding to the hyperlink to a browser cache on a user equipment, and
wherein the delivery of the content occurs without user selection of the hyperlink on the user equipment.
2. The method of claim 1 further comprising, after the issuing a request, waiting for at least one of the following events, before performing the issuing an emergency broadcast request, taken from the group consisting of:
expiration of a wait period; and
receiving the content corresponding to the hyperlink.
3. The method of claim 1 wherein the emergency alert comprises multiple hyperlinks, and wherein the issuing a request to a web server comprises issuing multiple requests for web pages, each one of the multiple requests for web pages corresponding to one of the multiple hyperlinks.
4. The method of claim 3 wherein each of the multiple hyperlinks has an associated priority, and wherein the issuing multiple requests for web pages is carried out according to the associated priority of each hyperlink.
5. The method of claim 1 wherein the issuing an emergency broadcast request to carrier networks comprises sending the emergency alert message in the form of a hyper text markup language (HTML) document.
6. The method of claim 5 wherein the issuing an emergency broadcast request to carrier networks comprises sending the content corresponding to the hyperlink in a hyper text markup language (HTML) document suitable for processing by a browser technology on a receiving user equipment.
7. The method of claim 1 wherein the cell broadcast center operates as an intermediate processing and routing node interposed between a Federal Alert Gateway and a supported group of mobile wireless carrier networks.
8. A non-transitory computer readable medium including computer executable instructions for performing a method on a cell broadcast center, for issuing an emergency alert message containing at least one hyperlink corresponding to content stored on a web server, wherein the method comprises:
receiving an emergency alert message at the cell broadcast center issued by an emergency alert system, wherein the emergency alert message includes a hyperlink to web content; and
processing 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 including both:
the emergency alert message, and
the content corresponding to the hyperlink,
wherein the issuing the emergency broadcast request, causes a delivery of the content corresponding to the hyperlink to a browser cache on a user equipment, and
wherein the delivery of the content occurs without user selection of the hyperlink on the user equipment.
9. The non-transitory computer readable medium of claim 8 further comprising, after the issuing a request, waiting for at least one of the following events, before performing the issuing an emergency broadcast request, taken from the group consisting of:
expiration of a wait period; and
receiving the content corresponding to the hyperlink.
10. The non-transitory computer readable medium of claim 8 wherein the emergency alert comprises multiple hyperlinks, and wherein the issuing a request to a web server comprises issuing multiple requests for web pages, each one of the multiple requests for web pages corresponding to one of the multiple hyperlinks.
11. The non-transitory computer readable medium of claim 10 wherein each of the multiple hyperlinks has an associated priority, and wherein the issuing multiple requests for web pages is carried out according to the associated priority of each hyperlink.
12. The non-transitory computer readable medium of claim 8 wherein the issuing an emergency broadcast request to carrier networks comprises sending the emergency alert message in the form of a hyper text markup language (HTML) document.
13. The non-transitory computer readable medium of claim 12 wherein the issuing an emergency broadcast request to carrier networks comprises sending the content corresponding to the hyperlink in a hyper text markup language (HTML) document suitable for processing by a browser technology on a receiving user equipment.
14. A cell broadcast center system for issuing an emergency alert message containing at least one hyperlink corresponding to content stored on a web server, the system comprising:
a processor; and
a non-transitory computer readable medium comprising computer-executable instructions that are executed by the processor to facilitate carrying out a method on the cell broadcast center comprising:
receiving an emergency alert message at the cell broadcast center issued by an emergency alert system, wherein the emergency alert message includes a hyperlink to web content; and
processing 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 including both:
the emergency alert message, and
the content corresponding to the hyperlink,
wherein the issuing the emergency broadcast request, causes a delivery of the content corresponding to the hyperlink to a browser cache on a user equipment, and
wherein the delivery of the content occurs without user selection of the hyperlink on the user equipment.
15. The system of claim 14 wherein the method further comprises, after the issuing a request, waiting for at least one of the following events, before performing the issuing an emergency broadcast request, taken from the group consisting of:
expiration of a wait period; and
receiving the content corresponding to the hyperlink.
16. The system of claim 14 wherein the emergency alert comprises multiple hyperlinks, and wherein the issuing a request to a web server comprises issuing multiple requests for web pages, each one of the multiple requests for web pages corresponding to one of the multiple hyperlinks.
17. The system of claim 16 wherein each of the multiple hyperlinks has an associated priority, and wherein the issuing multiple requests for web pages is carried out according to the associated priority of each hyperlink.
18. The system of claim 1 wherein the issuing an emergency broadcast request to carrier networks comprises sending the emergency alert message in the form of a hyper text markup language (HTML) document.
19. The system of claim 18 wherein the issuing an emergency broadcast request to carrier networks comprises sending the content corresponding to the hyperlink in a hyper text markup language (HTML) document suitable for processing by a browser technology on a receiving user equipment.
20. The system of claim 14 wherein the cell broadcast center operates as an intermediate processing and routing node interposed between a Federal Alert Gateway and a supported group of mobile wireless carrier networks.
