Wireless network analysis using per call measurement data

The advent of per call measurement data (PCMD) in Alcatel-Lucent network products has enabled an unprecedented view into code division multiple access (CDMA) network operation at the subscriber level. The timing information available in PCMD records allows for maximum-likelihood estimation of subscriber locations using experimental geo-location analysis software suite (GLASS) tools developed at Alcatel-Lucent. Spatial variations of traffic densities, lost call densities, and other phenomena can now be readily studied to better understand wireless network operation as experienced by subscribers. These types of tools can also incorporate financial and business details regarding subscribers to guide network operation and optimization activities more effectively. © 2007 Alcatel-Lucent.
