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. A method for caching data in a cellular network comprising:

calculating a time period for how long a mobile device will be serviced by an edge server in a cell site of a cellular network upon receiving travel information for the mobile device from the cellular network;

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

,

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

2. The method of claim 1, further comprising:

notifying a server in an adjacent cell site to begin caching data for the mobile device about to transition into the adjacent cell site.

3. The method of claim 1, further comprising:

preserving cached data on a server in response to determining a second mobile device requires the cached data.

4. The method of claim 3, further comprising:

releasing the preserved cached data in response to determining a second mobile device does not require the cached data.

5. The method of claim 1, wherein 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.

6. The method of claim 1, further comprising:

identifying cached data as one of likely and unlikely to be used based upon the received travel information for the mobile device from the cellular network.
