Abstract

A method, system, and computer program product for caching data in a cellular network is provided. Information from a cellular network regarding location, speed, direction of travel, and bandwidth for a user can be used to determine how much data should be cached for the user. More specifically, the time period for how long a user will be in a cell of a cellular network can be calculated using information received from the cellular network. The calculated time period can be used to calculate how much data will be used by a user for the calculated time period with only the amount of data needed for the time period being cached.

Claims

1-5. -5. (canceled)

6. A data caching system comprising:

an edge server with at least one processor and memory coupled to a domain name server (DNS) and disposed within a cell site of a cellular network;

a cache coupled to the edge server; and

,

a data caching module executing in memory of the edge server, the module comprising program code enabled to calculate a time period for how long a mobile device will be serviced by the cell site upon receiving travel data for the mobile device from the cellular network, to calculate how much data will be used by the mobile device for the calculated time period, and to cache the data within the cache to be used by the mobile device for the time period during which the mobile device remains serviced by the cell site.

7. The system of claim 6, wherein the data caching module further comprises program code enabled to notify an edge server in an adjacent cell site to begin caching data for the mobile device when it is determined that the mobile device is about to transition into the adjacent cell.

8. The system of claim 6, wherein the data caching module further comprises program code enabled to preserve cached data in the cache of the edge server in response to determining a second mobile device requires the cached data.

9. The system of claim 8, wherein the data caching module further comprises program code enabled to release cached data in response to determining a second mobile device does not require the cached data.

10. The system of claim 6, wherein the travel data is selected from the group consisting of field strength, location of the mobile device, speed of the mobile device, direction of travel of the mobile device, and bandwidth.

11. A computer program product for data caching in a cellular network, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code for calculating a time period for how long a mobile device will be serviced by a cell site of the cellular network upon receiving travel information for the mobile device from the cellular network;

computer readable program code for calculating how much data will be used by the mobile device for the calculated time period; and

,

computer readable program code for caching the data to be used by the mobile device for the time period in the cell site.

12. The computer program product of claim 11, wherein the computer readable program product further comprises:

computer readable program code for notifying an edge server in an adjacent cell site to begin caching data for the mobile device about to transition into the adjacent cell site.

13. The computer program product of claim 11, wherein the computer readable program product further comprises:

computer readable program code for preserving cached data on an edge server in response to determining a second mobile device requires the cached data.

14. The computer program product of claim 13, wherein the computer readable program product further comprises:

computer readable program code for releasing the preserved cached data in response to determining a second mobile device does not require the cached data.

15. The computer program product of claim 11, wherein the travel information is selected from the group consisting of field strength, location of the mobile device, speed of the mobile device, direction of travel of the mobile device, and bandwidth.
