Method and system for controlling access
First Claim
1. A system for access control having the following features:
- a) a mobile radio transmission/radio reception unit (BIU, BM3) has a first limited short-haul radio coverage area (BIU-BT), b) at least one electronic unit (MP, PC) contains a short-haul radio transmission/radio reception module (BM1, BM2) which has a second short-haul radio coverage area (BT1, BT2), c) the mobile radio transmission/radio reception unit (BIU, BM3) and the short-haul radio transmission/radio reception module (BM1, BM2) are in a form such that messages for identification are transmitted if there is at least some overlap between the first short-haul radio coverage area (BIU) and the second short-haul radio coverage area (BT1, BT2), d) the short-haul radio transmission/radio reception module (BM1, BM2) and the electronic unit (MP, PC) are connected to one another such, and are in a form such, that the transmitted identification messages are used for checking authorization to use the functions of the electronic unit (MP, PC), e) enabling means in a form such that use of the functions of the electronic unit (MP, PC) is enabled if there is authorization, and use of the functions is disabled if there is no longer any overlap.

Abstract
The invention relates to a method and a system for controlling access, comprising a mobile radio transmission/radio receiving device with a first limited short radio coverage range. The system also has at least one electronic device with a short-range radio transmission/radio receiving module which has a second limited short radio coverage range. The mobile radio transmission/radio receiving device and the short-range radio transmission/radio receiving module are configured in such a way that when the first short radio coverage range at least partially overlap, messages are transmitted for identification. The short-range radio transmission/radio receiving module and the electronic device are also interconnected and configured in such a way that the identification messages that are transmitted are used to check authorization to use the functions of the electronic device. The short-range radio transmission/radio receiving module and the electronic device also have release means which are configured in such a way that the functions of the electronic device are released for use in the case of authorization and the use of these functions is blocked when the overlap no longer exists.

9. A method for access control having the following features:
-
a) messages for identification are transmitted if there is at least some overlap between a first limited short-haul radio coverage area (BIU-BT) for a mobile radio transmission/radio reception unit (BIU, BM3) and a second limited short-haul radio coverage area (BT1, BT2) for a short-haul radio transmission/radio reception module (BM1, BM2) associated with an electronic unit (MP, PC), b) the transmitted identification messages are evaluated, c) use of the functions of the electronic unit (MP, PC) [lacuna] the short-haul radio transmission/radio reception module (BM1, BM2) is enabled if evaluation reveals that there is authorization to use the electronic unit (MP, PC), d) use of the function of the electronic unit (MP, PC) is disabled as soon as there is no longer any overlap. - View Dependent Claims (10, 11, 12, 13, 14)
