Abstract

A cache server disposed in a motor vehicle receives and caches content from a content distribution network when a load of a cellular link to the content distribution network is low. The cache server determines that the motor vehicle is turned off, broadcasts a wireless signal as part of a wireless network when the motor vehicle is turned off, and provides a device access to the content cached in the cache server via the wireless network.

Claims

1. A system, comprising:

a memory that stores instructions; and

a processor of a first cache server that executes the instructions to perform operations, the operations comprising;

receiving content when a load of a link to a network is low;

activating an access point when a vehicle is determined to be turned off;

broadcasting, by utilizing the access point and when the vehicle is turned off, a wireless signal that is part of a localized coverage area wireless network;

receiving, from a device, a request to join the localized coverage area wireless network;

authenticating the first cache server with a second cache server if the first cache server and the second cache server are both determined to be associated with a same service provider;

detecting, if the first cache server and the second cache server are both associated with the same service provider, whether the second cache server has an updated version of the content; and

providing, if the second cache server has the updated version of the content, access to the updated version of the content via the localized coverage area wireless network after the device is authenticated.

2. The system of claim 1, wherein the operations further comprise receiving authentication information from the device.

3. The system of claim 2, wherein the operations further comprise receiving a list of authentication information, and wherein the operations further comprise authenticating the device based on information in the authentication information matching the list of authentication information.

4. The system of claim 1, wherein the operations further comprise authenticating the device by receiving, from an authentication server, a notification signal indicating a verification of authentication information associated with the device.

5. The system of claim 1, wherein the operations further comprise caching the content in the first cache server.

6. The system of claim 1, wherein the operations further comprise determining that the vehicle is turned off.

7. The system of claim 1, wherein the operations further comprise generating a table to identify that the updated version of the content is located at the second cache server.

8. The system of claim 1, wherein the operations further comprise providing an address of the second cache server to the device to enable the device to access the updated version of the content.

9. The system of claim 1, wherein the operations further comprise providing the content to the device if the second cache server does not have the updated version of the content.

10. A method, comprising:

receiving, at a first cache server by utilizing instructions from memory that are executed by a processor, content when a load of a link to a network is low;

activating an access point when a vehicle is determined to be turned off;

broadcasting, by utilizing the access point and when the vehicle is turned off, a wireless signal that is part of a localized coverage area wireless network;

receiving, from a device, a request to join the localized coverage area wireless network;

authenticating the first cache server with a second cache server if the first cache server and the second cache server are both determined to be associated with a same service provider;

detecting, if the first cache server and the second cache server are both associated with the same service provider, whether the second cache server has an updated version of the content; and

providing, if the second cache server has the updated version of the content, access to the updated version of the content via the localized coverage area wireless network after the device is authenticated.

11. The method of claim 10, further comprising receiving a list of authentication information, and further comprising authenticating the device based on authentication information of the device matching the list of authentication information.

12. The method of claim 10, further comprising authenticating the device by receiving, from an authentication server, a notification signal indicating a verification of authentication information associated with the device.

13. The method of claim 10, further comprising determining that the vehicle is turned off.

14. The method of claim 10, further comprising generating a table to identify that the updated version of the content is located at the second cache server.

15. The method of claim 10, further comprising providing an address of the second cache server to the device to enable the device to access the updated version of the content.

16. The method of claim 10, further comprising providing the content to the device if the second cache server does not have the updated version of the content.

17. The method of claim 10, further comprising enabling the device to download a first portion of the updated version of the content while the vehicle is turned off.

18. The method of claim 17, further comprising enabling the device to download, via a cellular connection, a remaining portion of the updated version of the content when the vehicle is driving.

19. A computer readable device comprising instructions, which, when loaded and executed by a processor, cause the processor to perform operations, the operations comprising:

receiving, at a first cache server, content when a load of a link to a network is low;

activating an access point when a vehicle is determined to be turned off;

broadcasting, by utilizing the access point and when the vehicle is turned off, a wireless signal that is part of a localized coverage area wireless network;

receiving, from a device, a request to join the localized coverage area wireless network;

authenticating the first cache server with a second cache server if the first cache server and the second cache server are both determined to be associated with a same service provider;

detecting, if the first cache server and the second cache server are both associated with the same service provider, whether the second cache server has an updated version of the content; and

providing, if the second cache server has the updated version of the content, access to the updated version of the content via the localized coverage area wireless network after the device is authenticated.

20. The computer-readable device of claim 19, wherein the operations further comprise providing an address of the second cache server to the device to enable the device to access the updated version of the content.
