Method and Apparatus to Deliver Public Warning Messages

Abstract

A method and apparatus for a wireless transmit receive unit (WTRU) to receive an emergency situation notification. The method and apparatus include the WTRU receiving a paging message with an emergency situation notification, and the WTRU receiving scheduling information in a system information block.

What is claimed: 
     
         1 . A device comprising a processor configured to:
 receive a paging message, the paging message comprising an emergency notification indication;   receive a first system information block (SIB) based on receiving the emergency notification indication in the paging message, wherein the first SIB comprises scheduling information for at least a second SIB; and   receive at least the second SIB, wherein the second SIB comprises emergency warning information.   
     
     
         2 . The device according to  claim 1 , wherein first SIB comprises long term evolution (LTE) SIB type-1. 
     
     
         3 . The device according to  claim 1 , wherein the emergency warning information comprises a code that indicates an emergency type. 
     
     
         4 . A device comprising a processor configured to:
 send a paging message, the paging message comprising an emergency notification indication;   send a first system information block (SIB), wherein the first SIB comprises scheduling information for at least a second SIB; and   send at least the second SIB, wherein the second SIB comprises emergency warning information.   
     
     
         5 . The device according to  claim 4 , wherein first SIB comprises long term evolution (LTE) SIB type-1. 
     
     
         6 . The device according to  claim 4 , wherein the emergency warning information comprises a code that indicates an emergency type. 
     
     
         7 . A method implemented by a device, the method comprising:
 the device receiving a paging message, the paging message comprising an emergency notification indication;   the device receiving a first system information block (SIB) based on receiving the emergency notification indication in the paging message, wherein the first SIB comprises scheduling information for at least a second SIB; and   the device receiving at least the second SIB, wherein the second SIB comprises emergency warning information.   
     
     
         8 . The method according to  claim 7 , wherein first SIB comprises long term evolution (LTE) SIB type-1. 
     
     
         9 . The method according to  claim 7 , wherein the emergency warning information comprises a code that indicates an emergency type. 
     
     
         10 . The method according to  claim 7 , wherein the paging message is received by the device while the device is in radio resource control (RRC) IDLE mode. 
     
     
         11 . The method according to  claim 7 , wherein the paging message is received by the device while the device is in radio resource control (RRC) CONNECTED mode. 
     
     
         12 . The method according to  claim 7 , further comprising the device outputting a text message on a display based on the emergency warning information. 
     
     
         13 . The method according to  claim 7 , further comprising the device outputting a sound from a speaker based on the emergency warning information.
