Call data collected from the switch at a Mobile Telephone Switching Office is combined with location information of a mobile unit to generate information reports concerning the electromagnetic coverage of a geographic region. The collection of call data from the switch permits consideration of uplink information in the analysis of system performance. The uplink information reflects performance of specific equipment that is in use by the wireless customer. This uplink information may be combined with downlink and location information to remove from the performance evaluation transient effects associated with, for example, local terrain and other physical impairments.

DETAILED DESCRIPTION The present invention is briefly described as a method and system of monitoring the performance of a wireless telecommunications system.
In preferred embodiments there is disclosed a method and system of evaluating the coverage of a geographic area serviced by a mobile communications system.
In one aspect, the method includes obtaining uplink performance parameters related to at least one mobile unit from the mobile switching center, obtaining location information related to the location of the mobile unit, and analyzing the performance of the telecommunications system based on the uplink and downlink performance parameters and the location information to obtain analysis results.
In one aspect, the system includes monitoring performance of a wireless telecommunications system, the system including: a mobile unit forming a wireless connection to a radio base station; the radio base station connected to a switch; a base system analyzer coupled to said switch and which performs analysis of call data collected at the switch; a mobile PC transmitting location over a packet network to the base system analyzer; and wherein the system analyzer evaluates the performance of the telecommunications system based on uplink performance parameters and the location of the mobile unit.
In one aspect, the system includes monitoring performance of a wireless telecommunications system, the system including: a mobile unit forming a wireless connection to a switch; a means for collecting and transmitting uplink performance parameters of the wireless connection at the switch to a system analyzer; a means for sending the location of the mobile unit to the system analyzer; and wherein the system analyzer evaluates the performance of the telecommunications system based on the uplink performance parameters and the location of the mobile unit.
