Abstract

Methods, radioterminals, and broadcast message generation consoles provide location-based broadcast messaging for users. A method of operating a radioterminal can include receiving at the radioterminal over a wireless air interface a broadcast message that includes region information that defines a geographic region of applicability. A determination is made at the radioterminal whether the radioterminal is located in the region of applicability. A functional mode of the radioterminal is activated in response to the radioterminal being in the region of applicability. The functional mode may include activating a user interface of the radioterminal.

Claims

1. A broadcast message generation console comprising:

a communications interface communicatively coupled to a base station radio-transmitter; and

a controller that is configured to generate a broadcast message that comprises payload information and region information that defines a geographic region of applicability for the payload information, and to communicate the broadcast message through the communications interface for broadcast by the base station radio-transmitter to a geographic region that includes the geographic region of applicability.

2. The broadcast message generation console of claim 1, wherein the controller is further configured to generate within the broadcast message a group address that defines a group of radioterminals for which the broadcast message is applicable.

3. The broadcast message generation console of claim 1, wherein the controller is further configured to encode the region information within a header portion of the broadcast message.

4. The broadcast message generation console of claim 1, wherein the controller is further configured to generate a continuous broadcast message data stream that comprises the broadcast message, to encode the region information that can vary over time within multiple locations in the broadcast message data stream, to encode the payload information at defined locations in the broadcast message data stream between the locations of the encoded region information, and to communicate the broadcast message data stream through the communications interface for broadcast by the base station radio-transmitter.

5. The broadcast message generation console of claim 1, wherein the controller is further configured to communicate the broadcast message through the communications interface to a satellite base station transceiver for broadcast by a satellite to the geographic region that includes the geographic region of applicability.

6. The broadcast message generation console of claim 1, wherein the controller is further configured to communicate the broadcast message through the communications interface to a terrestrial cellular base station transceiver for broadcast to the geographic region that includes the geographic region of applicability.

7. The broadcast message generation console of claim 1, wherein the controller is further configured to communicate the broadcast message through the communications interface to a terrestrial digital television base station transmitter for broadcast to the geographic region that includes the geographic region of applicability.

8. A method of generating a broadcast message, the method comprising:

generating a broadcast message that comprises payload information and region information that defines a geographic region of applicability for the payload information; and

communicating the broadcast message to a base station radio-transmitter for broadcast to a geographic region that includes the geographic region of applicability.

9. The method of claim 8, wherein the generated broadcast message further comprises a group address that defines a group of radioterminals for which the broadcast message is applicable.

10. The method of claim 8, wherein generating a broadcast message comprises encoding the region information within a header portion of the broadcast message.

11. The method of claim 8, wherein generating a broadcast message comprises:

generating a continuous broadcast message data stream that comprises the broadcast message;

encoding the region information that can vary over time within multiple locations in the broadcast message data stream;

encoding the payload information at defined locations in the broadcast message data stream between the locations of the encoded region information; and

communicating the broadcast message data stream to the base station radio-transmitter for broadcast to the geographic region that includes the geographic region of applicability.

12. The method of claim 8, wherein communicating the broadcast message to a base station radio-transmitter comprises communicating the broadcast message to a satellite base station transceiver for broadcast by a satellite to the geographic region that includes the geographic region of applicability.

13. The method of claim 8, wherein communicating the broadcast message to a base station radio-transmitter comprises communicating the broadcast message to a terrestrial base station transceiver for broadcast to the geographic region that includes the geographic region of applicability.

14. The method of claim 8, wherein communicating the broadcast message to a base station radio-transmitter comprises communicating the broadcast message to a terrestrial digital television base station transmitter for broadcast to the geographic region that includes the geographic region of applicability.
