Online PN Offset Planniong: An Example of Cellular Network Autoconfiguration
01 January 2006
The growth in the number and density of cell sites in wireless networks continues to increase the importance of operational expenditures by service providers, which in turn creates demand for solutions that will allow networks to autoconfigure. In this paper we use PN offset planning as an example of autoconfiguration. We explore various types of data that might be available for autoconfiguration, and propose several online algorithms. We study how these data influence the choice of algorithm and impact the quality of the PN offset plan obtained. We also explore how these algorithms and the PN offset plans generated might be modified if we relax the online requirement and allow base stations to change their PN offsets.
