Alternate methods, devices and systems are presented for providing service
providers and/or end users of mobile stations to monitor and/or report
regions with high error rates and/or dead zones. A protocol is provided
such as to yield the error occurrence, error rate and/or the address of
the end user. In some embodiments it also contains location information
and time of day information. This information may be collected from the
G.P.S., and/or all or a portion of users when there is a significant
transmission difficulty and/or an abundance of errors. The collected data
forms a database which is analyzed to generate coverage maps. This may
include the dynamic aspects of the mobile network. In another aspect of
this invention, each mobile station periodically compares its current
location with the data base. The results of this comparison enables the
mobile unit to anticipate connection problems. In still another aspect of
the invention, the comparison is performed by the service provider which
notifies the end user.
