Abstract:
A method of monitoring a cellular call, comprising the steps of:(a) remotely accessing a switch at a first location, the switch switching one or more cellular sites in a cellular system; (b) remotely placing the switch in a call monitor mode; (c) recording call information related to a cellular call; (d) transmitting the call information to a second location; (e) storing, at the second location, the call information as data in a standard file format; and (f) displaying the data in a graphical format, wherein the step of displaying the data comprises presenting a first graph illustrating the reverse and forward signal strengths associated with a mobile device and a serving cell site involved in the cellular call, the first graph further illustrating reverse signal strengths of at least two cell sites neighboring the serving cell site, wherein the step of displaying the data further comprises presenting a second graph, simultaneously, and in temporal alignment, with the first graph, illustrating bit error rate (BER) being experienced by the cellular call, and wherein both the first and second graphs respectively illustrate at least one vertical line extending from a top to a bottom of the respective graph that is indicative of a call event that occurred with respect to the cellular call, the at least one vertical line illustrated on the first graph being horizontal registration with the vertical line on the second graph, whereby correlation between the first and second graphs, at least with respect to a call event, is facilitated.
