Beschreibung
Zusammenfassung:	A cellular mobile station (12) comprises a satellite positioning system signal reception interface (14) in the mobile station (12) for receiving satellite positioning system signals (16), a cellular communications network interface (24) in the mobile station (12) for communicating with a cellular communications network (28) and an information processor (22) coupled to the satellite positioning system signal reception interface (14) and the cellular communications network interface (24). The information processor (22) is arranged to evaluate the validity of a satellite positioning system based location fix by comparing it to at least one prior mobile station location fix.
