Multiple Language Emergency Alert System Method

Abstract

An Emergency Alert System (EAS) alert message is distributed in multiple languages. The multiple language EAS alert message can be provided via a single channel and/or multiple channels. The multiple language EAS alert message can be provided with a language vector indicating the languages provided and the location of respective language specific EAS alert messages. A mobile device receiving the multiple language EAS alert message, selects a preferred language specific EAS alert message and renders the EAS alert message in the preferred language.

What is claimed: 
     
         1 . A method comprising:
 receiving, from a primary emergency alert channel, a first transmission comprising a language vector;   determining, based on the language vector, a location of a preferred message of a plurality of messages, wherein the preferred message comprises an alert in a particular language that corresponds to a preferred language; and   receiving the preferred message from the location.   
     
     
         2 . The method of  claim 1 , wherein the location is associated with a broadcast channel. 
     
     
         3 . The method of  claim 2 , wherein the preferred message is interleaved in the broadcast channel with at least one other of the plurality of messages. 
     
     
         4 . The method of  claim 1 , wherein the language vector further comprises an indication of a message type. 
     
     
         5 . The method of  claim 1 , further comprising rendering the preferred message. 
     
     
         6 . The method of  claim 1 , wherein the first transmission comprises an Emergency Alert System alert message. 
     
     
         7 . The method of  claim 1 , further comprising establishing the preferred language. 
     
     
         8 . The method of  claim 1 , wherein the preferred language comprises a first preferred language and a second preferred language and the method further comprises:
 determining, based on the language vector, that none of the plurality of messages is in a first preferred language; and   selecting the preferred message based on the particular language corresponding to the second preferred language.   
     
     
         9 . The method of  claim 1 , the first transmission further comprising the alert in a default language. 
     
     
         10 . A method comprising:
 receiving a first transmission comprising a language vector;   receiving, subsequent to receipt of the first transmission, based on a preferred language, a second transmission that is separate from the first transmission, the second transmission comprising a multiple-language message, the multiple language message including a plurality of specific-language messages;   determining, based on the language vector and the preferred language, a location of a preferred message of the plurality of specific-language messages, wherein the preferred message is in a particular language that corresponds to the preferred language; and   retrieving the preferred message from the location.   
     
     
         11 . The method of  claim 10 , the first transmission further comprising the alert in a default language. 
     
     
         12 . The method of  claim 10 , wherein receiving the multiple-language message comprises receiving the multiple-language message via broadcast over a single channel, wherein the plurality of specific-language messages are interleaved in the single channel. 
     
     
         13 . The method of  claim 10 , wherein receiving the multiple-language message comprises receiving the multiple-language message via broadcast over a plurality of channels, wherein each message of the plurality of specific-language messages is broadcast via a respective one of the plurality of channels. 
     
     
         14 . The method of  claim 10 , wherein
 the language vector comprises a plurality of language indicators and a plurality of location indicators,   each language indicator of the plurality of language indicators denotes a respective particular language of a corresponding one of the specific-language messages, and   each location indicator is associated with a respective one of the plurality of language indicators and denotes a location of the corresponding one of the plurality of specific-language messages.   
     
     
         15 . The method of  claim 10 , further comprising rendering the preferred message. 
     
     
         16 . The method of  claim 10 , wherein the first transmission comprises an Emergency Alert System alert message. 
     
     
         17 . A nontransitory computer-readable storage medium comprising instructions that cause a processor executing the instructions to effectuate operations, the operations comprising:
 receiving, from a primary emergency alert channel, a first transmission comprising a language vector;   determining, based on the language vector, a location of a preferred message of a plurality of messages, wherein the preferred message comprises an alert in a particular language that corresponds to a preferred language; and   receiving the preferred message from the location.   
     
     
         18 . The nontransitory computer-readable storage medium of  claim 17 , wherein the language vector further comprises an indication of message type. 
     
     
         19 . The nontransitory computer-readable storage medium of  claim 17 , wherein the location is a broadcast channel and a location of the preferred message within the broadcast channel. 
     
     
         20 . The nontransitory computer-readable storage medium of  claim 19 , wherein the preferred message is interleaved in the broadcast channel with at least one other of the plurality of messages.
