| Popis: | A wireless call in a cellular network requires the cooperation of a wireless enabled device such as a cell phone and a dynamic set of base stations, antennas, and other network elements, with control of the call changing in response to changes in signal strength and the location of the mobile. The signaling between the network and mobile needed to manage the call generates a huge amount of signal strength data, some of which is seen only by the mobile placing the call and some of which is seen only by the network. This article describes some of the complexities of the signal strength data and provides a statistical model of the signals from the network to the wireless device that takes the time-dependent, spatial, and multivariate nature of the call into account. An approach to estimating the model parameters online as network data are collected, which would be useful for network monitoring, is also described and applied to a set of call data obtained from an active commercial CDMA (code division multiple... |
