Abstract

Determining that a first object associated with a first wireless link has a first caching priority; determining that a second object associated with a second wireless link has a second caching priority; and increasing the first caching priority relative to the second caching priority in response to one or more of: the first wireless link having a larger congestion than the second wireless link, the first wireless link having a weaker signal strength than the second wireless link, or the first object being associated with a higher status or priority than the second object.

Claims

1. A method comprising:

determining that a first object associated with a first wireless link has a first caching priority;

determining that a second object associated with a second wireless has a second caching priority; and

increasing the first caching priority relative to the second caching priority in response to one or more of;

the first wireless link having a larger congestion than the second wireless link,

the first wireless link having a weaker signal strength than the second wireless link, or the first object being associated with a higher status or priority than the second object.

2. The method of claim 1 further comprising:

determining a first cell identifier associated with the first wireless link based upon a previous download of the first object over the first wireless link; and

determining a second cell identifier associated with a second wireless link based upon a previous download of the second object over the second wireless link.

3. The method of claim 2 further comprising adjusting a first wireless loading attribute for a first cell associated with the first wireless link based upon current loading conditions at the first cell.

4. The method of claim 3 further comprising adjusting a second wireless loading attribute for a second cell associated with the second wireless link based upon current loading conditions at the second cell,

5. The method of claim 2 further comprising:

determining at least a first location identifier or a first user identifier associated with the first object based upon a previous download of the first object over the first wireless link; and

determining at least a second location identifier or a second user identifier associated with the second object based upon a previous download of the second object over the second wireless link.

6. The method of claim 5 further comprising adjusting a first customer equipment management priority attribute based upon at least one of the first location identifier or the first user identifier.

7. The method of claim 6 further comprising adjusting a second customer equipment management priority attribute based upon at least one of the second location identifier or the second user identifier.

8. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code being configured, with the at least one processor, to cause the apparatus to perform at least:

determining that a first object associated with a first wireless link has a first caching priority;

determining that a second object associated with a second wireless link has a second caching priority; and

increasing the first caching priority relative to the second caching priority in response to one or more of

the first wireless link having a larger congestion than the second wireless link,

the first wireless link having a weaker signal strength than the second wireless link, or

the first object being associated with a higher status or priority than the second object.

9. The apparatus of claim 8 wherein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform:

determining a first cell identifier associated with the first wireless link based upon a previous download of the first object over the first wireless link; and

determining a second cell identifier associated with a second wireless link based upon a previous download of the second object over the second wireless link

10. The apparatus of claim 9 wherein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform adjusting a first wireless loading attribute for a first cell associated with the first wireless link based upon current loading conditions at the first cell.

11. The apparatus of claim 10 wherein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform adjusting a second wireless loading attribute for a second cell associated with the second wireless link based upon current loading conditions at the second cell.

12. The apparatus of claim 9 wherein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform:

determining at least a first location identifier or a first user identifier associated with the first object based upon a previous download of the first object over the first wireless link; and

determining at least a second location identifier or a second user identifier associated with the second object based upon a previous download of the second object over the second wireless link.

13. The apparatus of claim 12 wherein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform adjusting a first customer equipment management priority attribute based upon at least one of the first location identifier or the first user identifier,

14. The apparatus of claim 13 w herein the computer program code is configured, with the at least one processor, to cause the apparatus to further perform adjusting a second customer equipment management priority attribute based upon at least one of the second location identifier or the second user identifier.

15. A computer program product including at least one computer-readable storage medium having computer-executable program code instructions stored therein. the computer-executable program code instructions including program code instructions for:

determining that a first object associated with a first wireless link has a first caching priority;

determining that a second object associated with a second wireless link has a second caching priority; and

increasing the first caching priority relative to the second caching priority in response to one or more of;

the first wireless link having a larger congestion than the second wireless link, the first wireless link having a weaker signal strength than the second wireless link, or the first object being associated with a higher status or priority than the second object.

16. The computer program product of claim 15 further comprising instructions for:

determining a first cell identifier associated with the first wireless link based upon a previous download of the first object over the first wireless link; and

determining a second cell identifier associated with a second wireless link based upon a previous download of the second object over the second wireless link.

17. The computer program product of claim 16 further comprising instructions for adjusting a first wireless loading attribute for a first cell associated with the first wireless link based upon current loading conditions at the first cell.

18. The computer program product of claim 17 further comprising instructions for adjusting a second wireless loading attribute for a second cell associated with the second wireless link based upon current loading conditions at the second cell.

19. The computer program product of claim 16 further comprising instructions for:

determining at least a first location identifier or a first user identifier associated with the first object based upon a previous download of the first object over the first wireless link; and

determining at least a second location identifier or a second user identifier associated with the second object based upon a previous download of the second object over the second wireless link.

20. The computer program product of claim 19 further comprising instructions for adjusting a first customer equipment management priority attribute based upon at least one of the first location identifier or the first user identifier.

21. The computer program product of claim 20 further comprising instructions for adjusting a second customer equipment management priority attribute based upon at least one of the second location identifier or the second user identifier.
