Positioning system and method
First Claim
1. A positioning system which uses GPS positioning and a mobile communications network (PLMN), characterized by the following system phases:
- i. a position inquiry is transmitted as a data transmission via a mobile communications network (PLMN) from a first inquiring mobile communications station (MS1), which is equipped with a GPS receiver, to a second mobile communications station (MS2), which is also equipped with a GPS receiver and about which position data is desired, ii. when an affirmative reply is given to the position inquiry at the second mobile communications station (MS2), the formation and transmission of the position data is initiated, iii. the position data is transmitted as a data transmission in a reply message from the second mobile station (MS2) via the mobile communications network (PLMN) to the first mobile station (MS1), iv. the position of the second mobile station (MS2) is shown on the display of the first mobile station (MS1).

Abstract
A positioning system which uses the Global Positioning System and a mobile communications network (PLMN), and a computer program for running the positioning system that uses the Global Positioning System and a mobile communications network (PLMN). It is a characteristic of the invention that a position data inquiry can be transmitted from a first mobile station (MS1), which is, for example, a combination of a GSM mobile communications station and a GPS receiver and which can determine positioning data using GPS via a mobile communications network (PLMN), advantageously using an SMS data transmission connection, to a second mobile station (MS2). When this inquiry is affirmatively answered in the second mobile station (MS2), the formation of and transmission of the position data to the first mobile station (MS1) via the mobile communications network (PLMN) is initiated. Lastly, the position of the second mobile station (MS2) is shown on the display of the first mobile station (MS1).
