Abstract: 1. Billing method for billing a call by a subscriber identified with an identification card (10) in a telecommunications network (2) to this subscriber, comprising: determination of the duration of the call, the duration of the call being measured by a time-measuring device (100) integrated into the identification card (10), determination of the amount to be billed based upon the determined call duration and at least one tariff table stored in the identification card (10), wherein a time controller (5) checks the time set in the identification card (10), and, if the time is not set correctly, transmits a time record to this identification card, and the amounts to be billed depend upon the time of day determined by said time-measuring device (100). 2. Billing method according to claim 1, wherein the tariff tables are stored in a tariff server (6), and can be remotely loaded into the identification card (10) and/or changed through said telecommunications network (2). 3. Billing method according to claim 2, wherein the tariff tables can be communicated from said tariff server (6) by means of special SMS short messages. 4. Billing method according to claim 3, wherein the tariff tables can be communicated from said tariff server (6) by means of USSD data. 5. Billing method according to any of claims 2 to 4, wherein after an identification card (10) has been logged into a telecommunications network (2) the tariff server (6) checks the version of the tariff table stored in this identification card (10), and, if necessary, loads the most recent version onto this identification card. 6. Billing method according to any of claims 1 to 5, wherein, after each logging in of an identification card (10), the time controller (5) checks the time set, and, if the time is not set correctly, transmits a time record to this identification card. 7. Billing method according to any of claims 1 to 6, wherein the transmitted time records are electronically signed. 8. Billing method according to any of claims 1 to 7, wherein stored in the identification card (10) of the subscriber are only the tariffs for areas of the telecommunications network in which he has already called and optionally tariffs for some pre-defined areas of the telecommunications network. 9. Billing method according to any of claims 2 to 8, wherein the transmission of tariff tables (10) between said tariff server (6) and the identification card (10) is encrypted. 10. Billing method according to any of claims 2 to 8, wherein the transmission of tariff tables (10) between said tariff server (6) and the identification card (10) is signed. 11. Billing method according to any of the preceding claims, wherein the amounts to be billed depend upon the location of the calling subscriber. 12. Billing method according to any of the preceding claims, wherein the amounts to be billed depend upon the location of the subscriber being called. 13. Billing method according to any of the preceding claims 1, wherein the amounts to be billed depend upon possible discounts. 14. Billing method according to any of the preceding claims, wherein said time-measuring device (100) comprises an oscillator integrated into the identification card (10). 15. Billing method according to claim 14, wherein said oscillator is a quartz oscillator. 16. Billing method according to any of the preceding claims, wherein the determined amounts are debited directly against a prepaid account in the identification card (10). 17. Billing method according to any of the preceding claims, wherein parameters upon which the billed amounts depend, are packed in billing records and are delivered to a billing server in said telecommunications network (2). 18. Billing method according to claim 17, wherein the billing records are electronically signed. 19. Billing method according to claim 18, wherein the billing records transmitted to the billing server are sorted and are transmitted to a corresponding financial services provider. 20. Billing method according to claims 17 to 19, wherein call detail records (CDRs) are generated in the telecommunications network (2), parallel to the billing records, as a check. 21. Billing method according to any of the preceding claims, wherein the use of resources not responsible for the traffic/communication processing are also billed in the identification card (10) on the basis of the stored tariff tables and said time-measuring device. 22. Identification card (10) for subscribers in a telecommunications network, which can be inserted in a terminal (1) in a removable way, containing: data processing means, which make possible the storage of data containing at least identification data of the subscriber in the telecommunications network (2), at least one tariff table, the amounts to be billed being determined on the basis of the determined call duration and this tariff table, an integrated time measuring device (100), with which the duration of the calls is determined, wherein the identification card (10) comprises means to receive time records, comprising time indications, transmitted to the identification card (10) by a time controller (5), and to set the time measuring device (100) with the transmitted time, and registers and programs for control of the time-measuring device (100) are stored in an area (12) of the identification card (10) not accessible to the subscriber. 23. Identification card (10) according to claim 22, wherein at least one tariff table is stored in the EEPROM of the identification card (10), and can be remotely loaded from a tariff server (6) in the telecommunications network (2) and/or changed. 24. Identification card (10) according to claim 23, wherein it can recognize and load tariff tables in special SMS short messages. 25. Identification card (10) according to claim 23, wherein it can recognize and load tariff tables in USSD data. 26. Identification card according to any of claims 22 to 25, wherein stored are only the tariffs for areas of the telecommunications network in which the subscriber has already called and optionally tariffs for some predefined areas of the telecommunications network. 27. Identification card according to any of claims 22 to 26, wherein it further contains TTP-decryption means in order to decrypt received tariff tables. 28. Identification card according to any of claims 22 to 25, wherein said time-measuring device (100) comprises an oscillator integrated into the identification card (10). 29. Identification card (10) according to claim 28, wherein said oscillator is a quartz oscillator. 30. Identification card according to any of claims 22 to 29, wherein it contains a prepaid account, against which the billed amounts are debited directly. 31. Identification card according to any of claims 22 to 30, wherein it contains means to pack the amounts to be billed in billing records and to send them to a billing collector (4) in said telecommunications network (2). 32.
