Non-GPS navigation
First Claim
1. A method comprising:
- automatically and repetitively inferring a current position of a cellular mobile unit utilizing a radio signal between said mobile unit and a cell site associated with a cellular network, said current position inferred by correlating the location of said mobile unit within said network for a given period of past time with geographic information corresponding to the location;
receiving destination information from the user of said mobile unit to determine a desired destination; and
providing guidance to the user from said current position to said desired destination.

Abstract
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.
