Abstract

A central host performs an automated method of updating multiple remote devices. In one embodiment, the host recognizes a predetermined download time and, in advance of the download time, transmits a calendar update to multiple remote devices. The calendar update includes the download time, and the remote devices may utilize the download time to set calendar reminders for entering an active state. Within a short time after reaching the download time, the host pushes download data to the remote devices by broadcasting the download data. In one aspect, the host may receive message acknowledgements from remote devices in response to a first calendar update, and the host may automatically transmit additional calendar updates to any remote devices that did not receive the first calendar update. Additional embodiments involve related methods and the terminal devices that receive the updates.

Claims

1. An automated method of downloading data from a central host to multiple remote wireless devices, the method comprising:

transmitting a first message from the host to each of the multiple remote wireless devices, the first message identifying a predetermined download time for a data download to the remote wireless devices such that the remote wireless devices can prepare to receive the data download;

automatically determining which of the multiple remote wireless devices did not receive the first message;

transmitting at least one second message from the host to each remote wireless device that did not receive the first message, the second message identifying the predetermined download time for the data download; and

substantially simultaneously broadcasting download data from the host to the multiple remote wireless devices such that the multiple remote wireless devices receive the download data from the host substantially simultaneously and store the download data,

wherein the first and second messages are usable by the multiple remote wireless devices to set calendar reminders in the multiple remote wireless devices for powering on or entering an active state allowing the download data to be received.

2. The method of claim 1, wherein the predetermined download time comprises an activation time for powering on the remote wireless devices.

3. The method of claim 1, further comprising:

receiving message receipt acknowledgements at the host from the remote wireless devices that receive the first message; and

automatically determining which of the multiple remote wireless devices did not receive the first message based at least on the received message receipt acknowledgements.

4. The method of claim 1, further comprising:

receiving distribution acknowledgements at the host from one or more of the multiple remote wireless devices indicating that the download data was received at the remote wireless devices; and

based at least on the received distribution acknowledgements, automatically updating distribution records to indicate which of the multiple remote wireless devices received the download data.

5. The method of claim 1, wherein the download data is broadcast to the remote wireless devices at or within a relatively short time after the predetermined download time.

6. The method of claim 1, wherein the download data comprises new software for the multiple remote devices.

7. The method of claim 1, wherein the download data comprises configuration settings for the multiple remote devices.

8. A computer program product comprising computer executable instructions, stored on a computer readable storage medium, for updating multiple remote devices from a central host, the instructions comprising instruction for:

transmitting a first message from the host to each of the multiple remote wireless devices, the first message identifying a predetermined download time for a data download to the remote wireless devices such that the remote wireless devices can prepare to receive the data download;

automatically determining which of the multiple remote wireless devices did not receive the first message;

transmitting at least one second message from the host to each remote wireless device that did not receive the first message, the second message identifying the predetermined download time for the data download; and

substantially simultaneously broadcasting download data from the host to the multiple remote wireless devices such that the multiple remote wireless devices receive the download data from the host substantially simultaneously and store the download data,

wherein the first and second messages are usable by the multiple remote wireless devices to set calendar reminders in the multiple remote wireless devices for entering an active state allowing the download data to be received.

9. The computer instructions of claim 8, further operable to perform operations comprising:

receiving message receipt acknowledgements at the host from the remote wireless devices that receive the first message; and

automatically determining which of the multiple remote wireless devices did not receive the first message based at least on the received message receipt acknowledgements.

10. The computer instructions of claim 8, further operable to perform operations comprising:

receiving distribution acknowledgements at the host from one or more of the multiple remote wireless devices indicating that the download data was received at the remote wireless devices; and

based at least on the received distribution acknowledgements, automatically updating distribution records to indicate which of the multiple remote wireless devices received the download data.

11. The computer instructions of claim 8, wherein the download data comprises new software for the multiple remote devices.

12. The computer instructions of claim 8, wherein the download data comprises configuration settings for the multiple remote devices.

13. A computer readable medium encoded with computer-executable instructions, wherein the computer instructions, wherein the computer-executable instructions, comprise instruction for:

transmitting a first message from the host to each of the multiple remote wireless devices, the first message identifying a predetermined download time for a data download to the remote wireless devices such that the remote wireless devices can prepare to receive the data download;

automatically determining which of the multiple remote wireless devices did not receive the first message;

transmitting at least one second message from the host to each remote wireless device that did not receive the first message, the second message identifying the predetermined download time for the data download; and

substantially simultaneously broadcasting download data from the host to the multiple remote wireless devices such that the multiple remote wireless devices receive the download data from the host substantially simultaneously and store the download data,

wherein the first and second messages are usable by the multiple remote wireless devices to set calendar reminders in the multiple remote wireless devices for entering an active state allowing the download data to be received.

14. The computer instructions of claim 13, further operable to perform operations comprising:

receiving message receipt acknowledgements at the host from the remote wireless devices that receive the first message; and

automatically determining which of the multiple remote wireless devices did not receive the first message based at least on the received message receipt acknowledgements.

15. The computer instructions of claim 13, further operable to perform operations comprising:

receiving distribution acknowledgements at the host from one or more of the multiple remote wireless devices indicating that the download data was received at the remote wireless devices; and

based at least on the received distribution acknowledgements, automatically updating distribution records to indicate which of the multiple remote wireless devices received the download data.

16. The computer instructions of claim 13, wherein the download data comprises new software for the multiple remote devices.

17. The computer instructions of claim 13, wherein the download data comprises configuration settings for the multiple remote devices.
