Description: A METHOD RELATING TO A VEHICLE PARKING CASH-PAYMENT SYSTEM The present invention relates to a method that pertains to a vehicle parking cash-payment system in which a mobile telephone can be used to commence and to terminate parking of a vehicle and in which a telephone user sends at least one code to a receiving computer via a mobile telephone system when commencing and terminating a parking period. Swedish Patent Specification No. 9800888-1 teaches a system for parking vehicles with the aid of a mobile telephone. According to this patent specification, data carried on a cash card or some like card in the possession of the telephone user and accepted by the parking system as a means of payment, and at least one user specific reference, are stored and tied together in a database belonging to the parking company concerned. Preferably, the user specific reference will include part of the number of the telephone used in connection with parking of the vehicle. The telephone number is caused to be detected by the parking system computer when the telephone is connected to a telephone number belonging to the parking system. According to one embodiment, the user specific reference includes a vehicle specific reference in the form of a plastic card or corresponding data carrier, wherein the reference is comprised of a machine readable code on the card. A vehicle specific reference may, of course, alternatively consist in the vehicle registration number. According to this embodiment, the cash card tied to the telephone number in the database is validated for billing purposes, by detecting the telephone number in question when connecting the telephone to the parking system. The vehicle parking system may be such as to require a car park attendant either to read-off the vehicle registration number or, alternatively, said machine readable code, when checking whether or not commencement of a parking period has been announced. In accordance with said patent, the car park attendants are equipped with a portable communications unit which is in wireless connection with a computer belonging to the company that owns the car park concerned and containing information relating to vehicles that have commenced a parking period but have not yet terminated parking. The communications unit may, for instance, be designed in accordance with the control unit described in Swedish Patent Specification 9700054-1. In this case, the car park attendant enters the identity of the parking zone concerned into the control unit, which then fetches from the computer a so-called parked car list that lists the vehicles properly parked in the parking zone in question, i.e. a list of the registration numbers of vehicles that have announced commencement of a parking period. The control unit then compares the read registration numbers with the parked car list and gives an indication when commenced parking has not been announced. Commencement and termination of a parking period can thus be announced very smoothly and effectively by a telephone. However, a problem arises in the case of people that do not have access to a cash card that can be used for vehicle parking billing purposes. These people cannot utilise the above- described system. The present invention solves this problem. The present invention thus relates to a method of cash payment in vehicle parking systems in which a mobile telephone is used to commence and to terminate parking of a vehicle and in which the telephone user sends at least one code to a receiving computer belonging to the parking system via the mobile telephone when commencing and terminating a parking period, wherein the method is characterised by using a start packet that includes a user specific code and a one-time code, such as a PIN code, a telephone number to said computer, and notice of the amount of money available for parking purposes; in that when connecting to the parking system the mobile telephone is caused to be connected to said computer via said telephone number, whereafter the user specific code and the one-time code are caused to be sent to said computer via the mobile telephone; in that said computer is caused to detect and store the number of the mobile telephone; in that said computer is caused to compare the user specific code and the one-time code; in that when agreement is found between the user specific code and the one-time code, the user specific code is stored together with the number of the mobile telephone and a given sum of money for use in paying parking fees; and in that commencement and termination of a parking period are respectively initiated by causing the mobile telephone to be connected to a predetermined telephone number belonging to said computer. The invention will now be described in more detail partly with reference to exemplifying embodiments thereof shown on the accompanying drawing, in which - Figure 1 is a schematic illustration of a telephone system and a vehicle parking system; and - Figure 2 illustrates a carrier provided with a user specific code. The present invention relates to a method of cash payment in vehicle parking systems in which a mobile telephone is used to commence and to terminate a parking period. When commencing and terminating parking of a vehicle, a user sends at least one code to a receiving computer 2 belonging to the parking system, via the mobile telephone 1. The code may consist of or include the number of the calling telephone. A telephone system of a known type is illustrated in Figure 1 and includes a base station 3 and an exchange or switching centre 4 belonging to the network operator concerned. The computer 2 is connected to the exchange 4 via a fixed telephone network in a known fashion. The computer 2 is connected to a database 5 in which information required for commencing and terminating parking respectively by means of a mobile telephone is stored. According to the invention, there is used a start packet which includes a user specific code, a one-time code, such as a PIN code, a telephone number to the computer 2, and notice of a sum of money for covering parking fees. Such a start packet is purchased by the user from a retail establishment that sells such start packets. This establishment may be a bookstore, a newsagent, a shop, or a special sales booth. When a person has purchased a start packet and wishes to connect with the parking system, he calls the telephone number of the parking system computer 2 given in the start packet on his mobile telephone. This number to the computer telephone is a number particularly intended for use when connecting to the system. When connection with the computer 2 has been established, the computer may ask the user, through the medium of a voice message, to state the user specific code and the onetime code. This is done by entering the codes on the telephone keypad. The codes are then sent to the computer. The computer is therewith caused to detect and store the number of the mobile telephone. The computer is then caused to compare the user specific code and the one-time code. In the production of the various parts of the start packet, all user specific codes have been paired together with an associated one-time code, this information being found stored in the database 5. When agreement is found between the user specific code and the one-time code, the computer 2 is caused to store the user specific code together with the number of the mobile telephone and said sum of money for which parking may take place. With regard to the sum of money, the start packet may cost SEK 500 to buy, of which SEK 450 is available for parking purposes. According to a first embodiment, the user specific code is a machine readable code and is provided in the start packet on a carrier 6, said carrier 6 being intended to be placed in the vehicle in a way which will enable the machine readable code 7 to be read from outside the vehicle when carrying out a parking control. Commencement and termination of a parking period are respectively initiated by causing the mobile telephone to be connected to a predetermined telephone number belonging to said computer. This number may be a number that applies to a given parking zone. When parking his vehicle, the user shall place the carrier with the machine-readable user specific code positioned so that a car park attendant is able to read the code. To this end, the carrier is intended to be placed in the vehicle in a manner that will allow the machine-readable code to be read from outside the vehicle when carrying out a parking check. For instance, when the carrier 6 has the form of an adhesive strip, the strip may be stuck to the inner surface of the vehicle windscreen with the code facing outwards. The code 7 may be a bar code that can be read mechanically by the car park attendant and compared with a parked card list stored in the computer 2. The code may also be given explicitly, as shown in Figure 2. According to a second, alternative, embodiment, the vehicle registration number is sent to said computer via the mobile telephone, when connecting to the parking system. In this case, the computer stores the vehicle registration number coupled to the user specific code. The registration number may be sent by means of a so called SMS message, or in some other way. For instance, the registration number may be transmitted with the use of codes where 0=00, 1=01, 2=02 .. 9=09 and where A=10, B=l 1, C=12, .. etc. When carrying out a parking control, the registration numbers of parked vehicles are compared with a so-called parked car list, by reading-off the registration numbers of parked vehicles with the aid of a suitable known control unit, and comparing the registration numbers coupled to a user specific code in the computer. When commencing a parking period, the computer 2 is caused to detect the number of a calling mobile telephone and to indicate in the computer the associated user specific code as belonging to a vehicle for which a parking fee has been paid. When terminating a parking period, the computer is caused to detect the number of a calling mobile telephone and therewith indicate in the computer the associated user specific code as belonging to a vehicle for which a parking fee has not yet been paid. When parking of a vehicle has been terminated, the computer is caused to subtract the relevant parking fee from the sum of money available for parking purposes, from an account tied to the telephone number or to the user specific code. Preferably, a telephone voice message informing the user of how much money is available for parking purposes or the length of parking time covered by available funds in the parking zone concerned will be generated by the computer at the commencement of a parking period. According to a preferred embodiment, there can be obtained a refill packet that includes at least one one-time code, such as a PIN code, and a given sum of money. This refill packet can be purchased in the same way as the start packet. When the refill packet is to be used, the mobile telephone is connected to the computer and the one-time code is sent to the computer via the mobile telephone. In this case, the mobile telephone number concerned is the number that has already been connected to the system on the basis of the start packet. The computer is then caused to detect the number of the mobile telephone and to store said number and the sum of money available together with the user specific code that belongs to the telephone number of the mobile telephone concerned. If no funds are available in the account, the telephone user can be informed to this extent through the medium of a telephone voice message when connecting the mobile telephone to the computer 2. The present invention thus solves the problem mentioned in the introduction. Although the invention has been described above with reference to several exemplifying embodiments thereof, it will be obvious that the system can be varied with respect to the number of codes required to obtain access to the system, among other things. The code carrier can also be designed for the code to be read magnetically or in some other machine- readable manner. The present invention shall not therefore be considered restricted to the above described exemplifying embodiments thereof, as variations and modifications can be made within the scope of the following Claims.
