## Abstract

A device includes a first network connection for connecting to a wireless local area network, a processor communicatively coupled to the first network connection, and a display communicatively coupled to the processor. The device includes memory storing instructions that cause the processor to effectuate operations. The operations include receiving, via the first network connection, a WEA message comprising an alert and an indication of a geographic area associated with the alert and causing the display to render an alert indication based at least on the WEA message.

## Claims

### Claim 1

A device comprising:
a first network connection for connecting to a wireless local area network (WLAN);
a second network connection for connecting to a cellular network;
a processor communicatively coupled to the first network connection;
a display communicatively coupled to the processor; and
memory storing instructions that cause the processor to effectuate operations, the operations comprising:
receiving, via the first network connection, a first wireless emergency alert (WEA) message comprising first alert and a first indication of a first geographic area associated with the first alert;
receiving, via the second network connection, a second WEA message comprising a second alert and a second indication of a second geographic area associated with the second alert, wherein the second geographic area overlaps the first geographic area;
comparing that comprises:
comparing the first geographic area and the second geographic area; and
comparing a temporal relationship between the first WEA message and the second WEA message;
based on the comparing, determining that the first alert and the second alert relate to a common event; and
based on the first alert and the second alert relating to the common event, causing the display to render an alert indication based on the first WEA message and the second WEA message.

### Claim 2 (depends on 1)

The device of claim 1, the operations further comprising determining that a location of the device is within the first geographic area, wherein causing the display to render the alert indication is responsive to the location being within the first geographic area.

### Claim 3 (depends on 2)

The device of claim 2, the operations further comprising:
receiving, via the first network connection, a third WEA message comprising a third alert and an indication of a third geographic area, the third geographic area associated with the third alert;
determining that the location of the device is outside of the third geographic area; and
based on the location being outside the third geographic area, not displaying an indication of the third alert.

### Claim 4 (depends on 2)

The device of claim 2, the operations further comprising:
receiving a third WEA message comprising a third alert;
comparing the first alert and the third alert; and
based on the comparing, determining that the third WEA message relates to the common event,
wherein the alert indication is further based on the third WEA message.

### Claim 5 (depends on 2)

The device of claim 2, the operations further comprising:
receiving a third WEA message;
comparing the first WEA message and the third WEA message;
based on the comparing, determining that an event associated with the first WEA message differs from an event associated with the third WEA message; and
causing the display to render an alert indication of the third WEA message.

### Claim 6

A method comprising:
receiving, at a device, via a wireless local area network (WLAN), a first wireless emergency alert (WEA) message comprising a first alert and a first indication of a first geographic area associated with the first alert;
determining that a location of the device is within the geographic area;
receiving, via a cellular network, a second WEA message comprising a second alert and a second indication of a second geographic area associated with the second alert, wherein the second geographic area overlaps the first geographic area;
comparing that comprises:
comparing the first geographic area and the second geographic area; and
comparing a temporal relationship between the first WEA message and the second WEA message;
based on the comparing, determining that the first WEA message and the second WEA message relate to a common event; and
based on the first alert and the second alert relating to the common event, causing the device to display an alert indication based on the first WEA message and the second WEA message.

### Claim 7 (depends on 6)

The method of claim 6, further comprising:
receiving, via the first network connection, a third WEA message comprising a third alert and an indication of a third geographic area, the third geographic area associated with the third alert;
determining that the location of the device is outside of the third geographic area; and
based on the location being outside the third geographic area, not displaying an indication of the third alert.

### Claim 8 (depends on 6)

The method of claim 6, further comprising:
receiving a third WEA message comprising a third alert;
comparing the first alert and the third alert; and
based on the comparing, determining that the third WEA message relates to the common event,
wherein the alert indication is further based on the third WEA message.

### Claim 9 (depends on 6)

The method of claim 6, further comprising:
receiving a third WEA message comprising a third alert;
comparing the first alert and the third alert;
based on the comparing, determining that the first alert and the third alert are the same; and
based on the content of the third WEA message being the same as the content of the first WEA message, not displaying an alert indication of the third WEA message.

### Claim 10

A non-transitory computer-readable storage medium storing instructions that cause a processor executing the instructions to effectuate operations, the operations comprising:
receiving, at a device, via a wireless local area network (WLAN), a first wireless emergency alert (WEA) message comprising a first alert and a first indication of a geographic area associated with the first alert;
receiving a second WEA message comprising a second alert and a second indication of a second geographic area associated with the second alert, wherein the second geographic area overlaps the first geographic area;
comparing that comprises:
comparing the first geographic area and the second geographic area; and
comparing a temporal relationship between the first WEA message and the second WEA message;
based on the comparing, determining that the first alert and the second alert relate to a common event; and
based on the first alert and the second alert relating to the common event, causing the device to display an alert indication based on the first WEA message and the second WEA message.

### Claim 11 (depends on 10)

The non-transitory computer-readable storage medium of claim 10, the operations further comprising determining that a location of the device is within the first geographic area,
wherein causing the device to display the alert indication is responsive to the location being within the first geographic area.

### Claim 12 (depends on 11)

The non-transitory computer-readable storage medium of claim 11, the operations further comprising receiving, via the first network connection, a third WEA message comprising a third alert and an indication of a third geographic area, the third geographic area associated with the third alert;
determining that the location of the device is outside of the third geographic area; and
based on the location being outside the third geographic area, not displaying an indication of the third alert.

### Claim 13 (depends on 10)

The non-transitory computer-readable storage medium of claim 10, wherein receiving the second WEA message comprises receiving the second WEA message via a cellular network.

### Claim 14 (depends on 10)

The non-transitory computer-readable storage medium of claim 10, the operations further comprising:
receiving a third WEA message comprising a third alert;
comparing the first alert and the third alert; and
based on the comparing, determining that the third WEA message relates to the common event,
wherein the alert indication is further based on the third WEA message.
