Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A method comprising: receiving at a cell site a wireless signal from a mobile wireless system; determining at least one of signal strength and signal error of the wireless signal; communicating the at least one of signal strength and signal error to the mobile wireless system; the mobile wireless system correlating the at least one of signal strength and signal error with location information collected by the mobile wireless system; communicating the at least one of signal strength and signal error through a data switch before communicating the at least one of signal strength and signal error to the mobile wireless system, wherein the data switch is part of a cellular digital packet data (CDPD) network; and communicating the at least one of signal strength and signal error through a voice switch before communicating the at least one of signal strength and signal error to the mobile wireless system.
Claim 2
Independent Claim
149 words
A method comprising: receiving at a cell site a wireless signal from a mobile wireless system; determining at least one of signal strength and signal error of the wireless signal; communicating the at least one of signal strength and signal error to the mobile wireless system; the mobile wireless system correlating the at least one of signal strength and signal error with location information collected by the mobile wireless system; communicating the at least one of signal strength and signal error through a data switch before communicating the at least one of signal strength and signal error to the mobile wireless system, wherein the data switch is part of a cellular digital packet data (CDPD) network; and communicating the at least one of signal strength and signal error through a voice switch before communicating the at least one of signal strength and signal error to the mobile wireless system.
Claim 3
Independent Claim
98 words
A method comprising: receiving at a cell site a wireless signal comprising location data from a mobile wireless system, the location data received via a voice channel; determining at least one of a signal strength and signal error for the wireless signal; communicating the at least one of a signal strength and signal error to a processing device via a voice switch; communicating the location data to the processing device via a data switch; and the processing device causing the at least one of a signal strength and signal error to be visually correlated with the location data.
Claim 4
Independent Claim
98 words
A method comprising: receiving at a cell site a wireless signal comprising location data from a mobile wireless system, the location data received via a voice channel; determining at least one of a signal strength and signal error for the wireless signal; communicating the at least one of a signal strength and signal error to a processing device via a voice switch; communicating the location data to the processing device via a data switch; and the processing device causing the at least one of a signal strength and signal error to be visually correlated with the location data.
Claim 5
Dependent Claim
52 words
The method of claim 2 , further comprising: communicating the at least one of a signal strength and signal error to the processing device in a first base station; communicating the location data to a second base station; and the second base station communicating the location data to the first base station.
Claim 6
Dependent Claim
22 words
The method of claim 3 , further comprising: the second base station communicating with the first base station via a CDPD modem.
Claim 7
Dependent Claim
13 words
The method of claim 2 wherein the location data is received via CDPD.
