Non-GPS based navigation may be implemented by a cellular network service
provider. The service provider may have data regarding a cellular
radiotelephone's location within its coverage area. Geographic data for
the cell phone's location may be obtained from a geographic database.
Accordingly, navigational assistance may be provided to the user of the
cellular radiotelephone through the interplay between the provider,
telephone and geographic database. Additionally, the telephone may have a
database storing telephone number-address pairs. Thus, when the user of
the telephone inputs a telephone number as destinational information, the
address corresponding to that phone number may be the destination
location to which the user is traveling.
