US 8,275,350 B2 · Systems and methods for mapping commercial mobile alert service message attributes to a cell broadcast interface

Abstract

Cell broadcast protocols are used to distribute emergency alerts to mobile devices. Emergency alerts may be received from an emergency provider or governmental agency. Parameters of an emergency alert may be derived and mapped to parameters of a cell broadcast message, which may then be transmitted to mobile devices. In one embodiment, attributes of an emergency alert are mapped to a first parameter of a cell broadcast message, and the contents of the emergency alert are mapped to the first parameter of the cell broadcast message. If the contents of the emergency alert exceed the available space in the first parameter, the remaining contents of the emergency alert are mapped to a second parameter of the cell broadcast message.

Dependent claims

A system comprising:

a memory comprising computer instructions;
a receiver configured to receive a commercial mobile alert message;
a processor coupled to the memory and the receiver, wherein when executing the computer instructions, the processor is configured to:
determine attributes of the commercial mobile alert message;
determine contents of the commercial mobile alert message;
map the attributes of the commercial mobile alert message to a first 27 octets of a CBS-Message-Information-Page1 parameter of a 3GPP Write/Replace message of Request/Indication primitive type;
and
map at least a portion of the contents of the commercial mobile alert message to the CBS-Message-Information-Page1 parameter of the 3GPP Write/Replace message;
and
a transmitter configured to transmit the 3GPP Write/Replace message.

7 more elements

A method comprising:

receiving a commercial mobile alert message from an alert gateway at a cell broadcast center;
determining attributes of the commercial mobile alert message at the cell broadcast center;
determining contents of the commercial mobile alert message at the cell broadcast center;
generating a 3GPP Write/Replace message of a Request/Indication primitive type by mapping the attributes of the commercial mobile alert message to a first 27 octets of a CBS-Message-Information-Page1 parameter and mapping at least a first portion of the contents of the commercial mobile alert message to the CBS-Message-Information-Page1 parameter;
and
transmitting the 3GPP Write/Replace message.
