Abstract

Traveling on highways may take some time (not because of the traffic jam but because of the distance between the cities) and during these long hours the driver and/or the passengers have limited choices to pass the time. To entertain the crew, one option would be to be able to get ‘on-demand’ access to audio books where the user would make an initial selection and where the audio content would be dynamically loaded as long as the journey goes on.

Automatic Provisioning of Audio Books on Highways

The invention proposes an 'on-demand' infrastructure to provision mobile devices. The example of the provisioning of audio books while a car is traveling on a highway is used to illustrate the different concepts and technologies used by the invention. The device to be provisioned, in our case an audio book reader, has a unique identifier and can communicate with the outside world not only to identify itself but to also receive digital content. The identification of the device can be done using Radio Frequency Identification (RFID) technology and transmission can be supported by Bluetooth* protocols. By crossing the space of the first roadside beacon on its way, the device identifies itself and downloads the index of the digital content available.

The user then scans the content and makes his selection. The selected information is sent and processed. A central provisioning system, which has the knowledge of the roadside beacons starts transferring the digital content to the different roadside beacons on the path of the vehicle. The digital content to download is distributed to successive roadside beacons. This step is necessary because of the limited size of the digital content to be downloaded between the roadside beacon and the mobile device. For example, based on the assumption that we have a roadside beacon every 10 miles and the average speed is 60 mph, the first roadside beacon will be provisioned with ~10 minutes of digital content, the next one will be provisioned with the next 10 minutes of

digital content and so on. By using the RFID as a unique identifier, the central system processes the average speed of the vehicle and can take the appropriate decisions related to the size of the content to provision on each roadside beacon on the path of the vehicle.

The invention includes several components:

A portable device, the audio book reader, that has a unique identifier. This

portable device, besides its audio functionality has a short range communication system (could be based on Bluetooth technology) to exchange information with the roadside beacons. It also include a display and a user interface allow...
