Abstract

A cellular positioning system (1) and a mobile terminal (2), where a unique code, the predefined free time intervals (4) or the time period of other code slots (5) located between any transmitted or received pair of code (4, 5), the arrival time of each pair of codes, the timing advances defined either in mobile terminal or in three or more base stations (3, 10), and an area map transmitted by the base stations are used in order to compute and define the exact position, speed and direction of the mobile terminal (2) continuously or whenever required, either in the computing unit (6) or in the mobile terminal (2) itself, either when the mobile terminal is in active mode or in idle. In the present invention at least three base stations (3, 10) communicate with the mobile terminal (2) in order to define its position, speed and direction by measuring the distances between the base stations (3 or 10) and the mobile terminal (2) and computing the intersection points (A, B), of three or more distance measurements. The continuous location positioning method presented in this cellular positioning system also enables the network to compute the moving speed and direction of the mobile terminal by taking into computation the change (ΔD)) in the coordinates of its position and the time (t) passed during this change. Furthermore, three inventive applications: 1-Teleparking system (Fig. 2), 2-Teleradar system, 3-Theft detection system, are presented in the inventive cellular positioning system.

- said unique code may be comprised of the subscriber number or/and the equipment number of the mobile terminal or any other code allocated for the communications between the mobile terminal and the base stations, which is sent to or received from the base stations (3), (10), of the cellular positioning system (1) wherein the arrival time of said codes are recorded, and the position and/or moving speed and direction of said mobile terminal is defined in the computing unit (6) or in the mobile terminal itself, resulting in an intersection point A or B or C taking into computation said timing advances and/or pre-defined free time intervals, code's time period, the speed of radio signals, and the geographical position of said base stations;
- said unique code may be any signal which is transmitted in any time division or frequency division or code division multiple access methods, either by said mobile terminal (2) or the base stations (3), (10);
- said codes of a mobile terminal (2) may be requested, by three or more base stations (3), (10) of said cellular positioning system (1) or alternatively they may be transmitted by said base stations all the time or whenever said mobile terminal (2) requests it;
- three base stations (3), (10), from which each one is synchronised with said mobile terminal so that when the mobile terminal (2) sends its null timing advance to each base station, the base stations define their own timing advances and send them either to the computing unit (6) or to the mobile terminal (2); and that the defined timing advances may be used in both either the mobile terminal (2) or in the base stations (3), (10) to define the position of the mobile terminal (2); 15
- the information of the positioned location, defined by said computing unit (6) can be sent back to the mobile terminal (2) and be monitored for its user information;
- the base stations (3), (10) of the inventive cellular positioning system (1) send to the mobile terminal (2) whenever required an area map which is updated while mobile terminal (2) is moving from a cell area or crevice area to the other; and that the said area map can be monitored on the screen (9) of the mobile terminal (2) where the position of the mobile terminal (2) can be shown:
- the cells of said cellular positioning system can be comprised of the cells of a terrestrial or a mobile satellite communication system or they can be a combination of the cells of both terrestrial and mobile satellite communication systems;
- the base stations of said cellular positioning system can be comprised of one or more terrestrial base stations (10) and one mobile satellite base station (18) where the intersection point of two or more distance measurements (C) defines the position, moving speed or direction of said mobile terminals;
- the cells of said cellular positioning system may be comprised of pico-, micro or macro cells of any cellular communication system;
- said mobile terminal (2) is equipped with means in order to receive from the base stations (3), (10), (18) the computed location information together with an area map which can be monitored on the screen (9) of the mobile terminal (2);
- said mobile terminal can be any portable/mobile telephone capable of communicating with cellular communication systems;
- said mobile terminal (2) is equipped with means for defining its position by sending some bursts which includes a unique code allocated for the mobile terminal (2) with a null timing advance to the three or more base stations (3), (10), (18) of said cellular positioning system (1) and to receive a new value of timing advance computed by each base station, and that the values of three timing advances which indicate the distances between said base stations and the mobile terminal (2) are used to define the position of the mobile terminal resulting in intersection points A or B or C. 16
2. A cellular positioning system (1) as claimed in claim 1, characterised in that the moving speed of said mobile terminal (2) can be defined both in the mobile terminal and the base stations (3), (10), by measuring, continuously in any given time, the distances between said base stations and mobile terminal (2), taking into computation the change (ΔD ) in distances between the mobile terminal and base stations (3), (10), and the time (t) passed during this change.
3. A cellular positioning system (1) comprised of a mobile tele-parking system (17) as claimed in claim 1, characterised in that when a driver having a mobile telephone (12) has parked his/her vehicle in the parking space (16), he/she dials on his/her vehicle or hand-held mobile telephone a telephone number which is allocated for parking charges in a charging centre (11), and that after this, the location of said mobile telephone is positioned by said computing unit (6) of the cellular positioning system ( 1 ) which after the information about the position of said vehicle will be forwarded to the database (13); and that;
- in database (13), in accordance with each mobile subscriber number the subscriber and her/his vehicle's register number and other required information are recorded in advance;
- when the driver collects the vehicle from the parking space (16), she/he again telephones to the number allocated for parking charges whereupon the database (13) records that the parking period has been terminated;
- the parking charges are added to the telephone bills of the subscribers;
- the locations of the parking spaces (16) are in advance measured, calibrated and defined by said cellular positioning system (1) and are recorded in the database (13) so that for each parked vehicle parking place-related tariffs can be counted;

- the location of the parking inspector (14) is positioned by said cellular positioning system and then the information about all those parked vehicles (12) whose parking spaces are near to the location of the parking inspector (14). are sent to the 17
inspector's device (15) from which parking inspector can see all required information of nearby parked vehicles and/or their owners;
- the parking inspector's device (15) communicates with the database (13) in order to only receive the required information from the database (13) based on the position of the parking inspector (14) and parked vehicles (12), and that the required information may include at least the vehicle register number and/or its colour, model, and owner;
- the position of the parking inspector's mobile device (15) is located by said cellular positioning system (1) whenever parking inspector contacts the database (13) through his mobile device (15) and according to the positioned location of the parking inspector the information about the parked vehicles, which are close to the parking inspector, will be sent from the database (13) to the inspector's mobile device (15);
