Abstract

A mobile device is configured to process a Commercial Mobile Alert Message System (CMAS) alert message via various processing states. The various states allow the mobile device to implement user preferences, such as, for example, a preference to not be notified of a CMAS alert and to provide notification of an alert in a specified manner. Example states include an idle state, an analysis state, a storage state, a render state, a notification state, and a wait state.

Claims

1. A method for processing a Commercial Mobile Alert Message System (CMAS) message, the method comprising:

in an idle state, receiving a CMAS message;

from the idle state, entering an alert analysis state;

in the alert analysis state, determining if the received CMAS message is to be rendered;

if it is determined that the received CMAS is not to be rendered, returning to the idle state;

if it is determined that the received CMAS is to be rendered, entering a render state;

in the render state, rendering the received CMAS message;

from the render state, entering a notify state;

in the notify state, providing a notification of the received CMAS message;

from the notify state, entering a wait state;

in the wait state, if acknowledgment is not received, returning to the notify state; and

in the wait state, if acknowledgment is received, returning to the idle state.

2. The method in accordance with claim 1, further comprising:

in the alert analysis state, if it is determined that the received CMAS is to be rendered, storing the received CMAS message before entering the render state.

3. The method in accordance with claim 1, wherein:

a number of times a transition occurs between the wait state and the notify state is predetermined; and

when the predetermined number of times is reached, the idle state is reentered.

4. The method in accordance with claim 1, wherein the received CMAS message is at least one of visually rendered, mechanically rendered, or audibly rendered.

5. The method in accordance with claim 1, wherein the notification is provided at least one of visually, mechanically, or audibly.

6. A mobile device configured to process a Commercial Mobile Alert Message System (CMAS) message, the mobile device configured to:

in an idle state, receive a CMAS message;

from the idle state, enter an alert analysis state;

in the alert analysis state, determine if the received CMAS message is to be rendered;

if it is determined that the received CMAS is not to be rendered, return to the idle state;

if it is determined that the received CMAS is to be rendered, enter a render state;

in the render state, render the received CMAS message;

from the render state, enter a notify state;

in the notify state, provide a notification of the received CMAS message;

from the notify state, enter a wait state;

in the wait state, if acknowledgment is not received, return to the notify state; and

in the wait state, if acknowledgment is received, return to the idle state.

7. The mobile device in accordance with claim 6, further configured to:

in the alert analysis state, if it is determined that the received CMAS is to be rendered, store the received CMAS message before entering the render state.

8. The mobile device in accordance with claim 6, wherein:

a number of times a transition occurs between the wait for acknowledgement state and the notify state is predetermined; and

when the predetermined number of times is reached, the idle state is reentered.

9. The mobile device in accordance with claim 6, wherein the received CMAS message is at least one of visually rendered, mechanically rendered, or audibly rendered.

10. The mobile device in accordance with claim 6, wherein the notification if provided at least one of visually, mechanically, or audibly.
