Abstract

The invention includes a method for determining an expenditure associated with a network. A method includes obtaining network information associated with a portion of a network, categorizing each of a respective plurality of cells as one of an aggregated cell and a non-aggregated cell, determining an aggregating node configuration for at least one aggregating node associated with at least one base station associated with an aggregated cell, determining a deaggregating node configuration for at least one deaggregating node associated with at least one of the at least one aggregating node, and determining the expenditure according to at least one of the aggregating node configuration and the deaggregating node configuration. The categorization of cells is performed using the network information.

Claims

1. A method for determining an expenditure for a portion of a network, comprising:

partitioning the portion of the network into at least one geographical region according to at least one partitioning parameter associated with each of a plurality of base stations located within the geographical region;

defining at least one cluster within each of the at least one region, the at least one cluster defined in a manner tending to maximize a base station density of each of the at least one cluster;

determining an aggregating node configuration associated with an aggregating node, the aggregating node configuration determined using the base station density of one of the at least one cluster associated with the aggregating node;

determining a deaggregating node configuration associated with a deaggregating node, the deaggregating node configuration determined using the aggregating node configuration; and

determining the expenditure using the base station density associated with each of the at least one cluster.

2. The method of claim 1, wherein the at least one partitioning parameter comprises at least one of a traffic demand, a subscriber density, and a base station configuration.

3. The method of claim 1, wherein each of the at least one cluster comprises a cluster radius determined according to a tariff structure.

4. The method of claim 1, wherein the expenditure comprises one of a capital expenditure and an operational expenditure.

5. The method of claim 1, wherein the expenditure comprises one of a capital expenditure and an operational expenditure.

6. The method of claim 5, wherein the determining the capital expenditure further comprises:

applying at least one pricing model to the aggregating node configuration and the deaggregating node configuration.

7. The method of claim 5, wherein the determining the operational expenditure further comprises:

determining at least one equipment-based operational expenditure associated with;

at least one aggregating access link between at least one base station associated with the at least one cluster and the aggregating node; and

at least one aggregating backhaul link between the aggregating node and the deaggregating node;

determining at least one link-based operational expenditure associated with the at least one aggregating access link and the at least one aggregating backhaul link; and

determining the operational expenditure using the at least one equipment-based operational expenditure and the at least one link-based operational expenditure.

8. The method of claim 1, wherein said determining a configuration of the aggregating node comprises using information indicative of a traffic load to be supported by the aggregating node;

and

determining the expenditure for the aggregating node using the configuration of the aggregating node.

9. The method of claim 8, wherein the information indicative of traffic to be supported by the aggregating node comprises at least one of a number of base stations to be supported by the aggregating node and an average cell area of the base stations to be supported by the aggregating node.

10. The method of claim 1, wherein determining the configuration of the aggregating node comprises:

determining a number of base stations associated with a geographical region covered by a portion of the network;

determining an aggregation fraction indicative of a number of the base stations associated with the geographical region that are to be supported by the aggregating node; and

determining a configuration of the aggregating node using the aggregation fraction and the information indicative of the traffic load to be supported by the aggregating node.

11. The method of claim 10, where determining the number of base stations associated with the geographical region covered by the portion of the network comprises:

determining a total number of base stations of the network;

determining an area of a geographical region covered by the network;

determining an area of the geographical region covered by the portion of the network; and

determining the number of base stations associated with the portion of the network using the total number of base stations of the network, the area of the geographical region covered by the network, and the area of the geographical region covered by the portion of the network.

12. The method of claim 10, wherein the aggregating fraction is determined using the number of base stations associated with the geographical region covered by the portion of the network and a tariff structure.

13. The method of claim 10, wherein the tariff structure is a function of geographical distance.

14. The method of claim 1, wherein the information indicative of traffic load on the base stations to be supported by the aggregating node comprises, for each base station to be supported by the aggregating node, link types of links supported by the base station and utilization of the links supported by the base station.
