Abstract

A method, computer program product, and computer system directed to an online and distributed optimization framework for wireless analytics. A radio network controller determines a ranking for each of a plurality of received objects using a plurality of similarity graphs. The radio network controller extracts a common structure by collaborative filtering data associated with a plurality of user devices and the plurality of received objects. The common structure is analyzed to infer usage patterns within a time slot. The radio network controller stores a subset of the ranked objects of the plurality of received objects in response to the analysis.

Claims

1. A computer-implemented method comprising:

determining, by a radio network controller, a ranking for each of a plurality of received objects using a plurality of similarity graphs for a plurality of base stations, wherein the plurality of received objects include data files received from at least one of the plurality of base stations, the ranking calculated by

2. The computer-implemented method of claim 1 wherein the plurality of similarity graphs include an object-object similarity graph, a base station-base station similarity graph, and a user-user similarity graph.

3. The computer-implemented method of claim 1 wherein the ranking for each of the plurality of received objects is based upon, at least in part, a demand at each of the plurality of base stations, a weighting factor for premium and non-premium demands, and a bandwidth associated with each object of the plurality of received objects.

4. The computer-implemented method of claim 1 wherein storing a subset of the ranked objects of the plurality of received objects further comprises cooperatively storing the subset of ranked objects across the plurality of base stations.

5. The computer-implemented method of claim 1 further comprising identifying which of the plurality of user devices and the plurality of received objects appear together in the plurality of similarity graphs.

6. The computer-implemented method of claim 1 further comprising generating an online update of the ranking for each of the plurality of received objects and the plurality of users.

7. The computer-implemented method of claim 1 wherein the collaborative filtering is based upon, at least in part, co-clustering.
