1. A method of determining a location of a User Equipment (UE), the method comprising:
- generating, by the UE, a database of location data for a plurality of locations by;
performing a location determination for each of the plurality of locations, the location determination being made from a plurality of navigation signals received by the UE at each of the plurality of locations;
determining an identity of a respective cell of a cellular communication system in which the UE is located at each of the plurality of locations; and
storing data indicating each of the plurality of locations and the respective cell identity for each of the plurality of locations;
receiving at least one navigation signal at a particular area;
determining an identity of a cell in which the UE is currently located at the particular area; and
determining the location of the UE at the particular area using the at least one navigation signal, the identity of the current cell, and at least a portion of the data stored in the database.

5. A method of determining a location of a User Equipment (UE), the method comprising:
-
receiving, by the UE, a plurality of navigation signals and information for a cell of a communication system in which the UE is located at a first location; calculating a range of locations for the UE from the received navigation signals; identifying a previously visited location from visited locations stored in the UE as an estimate of the first location, the previously visited location being located within a predetermined distance from the range of locations; and displaying the estimate of the first location to a user. - View Dependent Claims (6, 7, 8, 9)

10. A User Equipment (UE) comprising:
-
a satellite communication module for receiving a plurality of navigation signals; a cellular network module for receiving information for a cell of a cellular communication network in which the UE is located; a memory for storing data; and a controller that calculates a range of locations for the UE from the received navigation signals, identifies a previously visited location from visited locations stored in the UE as an estimate of the first location, and displays the estimate of the first location to a user, wherein the previously visited location is located at or within a predetermined distance from the range of locations.
