Abstract

Methods and apparatus for anonymous identification of the profiles of subscribers in a communication system, wherein subscribers define and store subscriber-specific profiles via a respective input unit in a respective communication terminal and/or in a respective module respectively coupled to a respective communication terminal. Each respective module communication terminal is used to collect the profiles of other subscribers of the communication system on the basis of a wireless, locally defined network technology which are compared to the profiles defined and stored in the respective communication terminal whereupon they are discarded according to a subscriber-specific correlation threshold or communicated to the respective subscriber. A communication link is set up by an intermediate coupled provider of the communication system between subscribers when the respective subscriber activation occurs. A module is also disclosed that can be integrated in a mobile communication terminal or on a mobile communication terminal via an interface. The module includes a memory unit for storing profiles, a collector unit functioning on the basis of a wireless, locally defined network technology for collecting (scanning) profiles of subscribers, a correlation unit for comparing profiles, and a signaling/synchronizing unit.

Claims

1-12. -12. (canceled)

13. A method for anonymous identification of profiles of subscribers in a communications system comprising:

defining subscriber-specific profiles via an input unit of a communication appliance and storing the subscriber-specific profiles in at least one of the communication appliance and a module that is coupled to the communication appliance;

collecting profiles of other subscribers in the communications system through the module coupled to the communication appliance using wireless, locally restricted network technology;

comparing the collected profiles with the profile defined and stored in one of the communication appliance and module, wherein the profile is one of rejected or signaled to another subscriber based on comparison with a subscriber specific correlation threshold; and

establishing a communication connection between subscribers via an intermediate provider in the communications system whenever subscriber end activation takes place.

14. The method as claimed in claim 13, wherein the wireless, locally limited network technology is one of a local area network (LAN) and a personal area network (PAN) utilizing Bluetooth technology.

15. The method as claimed in claim 13, wherein a respective mobile communication appliance, which operates in accordance with a standard, is used as the respective communication appliance, with the standard being selected from a group consisting of GSM, GPRS, EDGE and UMTS.

16. The method as claimed in claim 13, wherein each module of a subscriber is allocated an ID number.

17. The method as claimed in claim 13, wherein the input unit comprises a computer.

18. The method as claimed in claim 13, wherein each subscriber in the communications system is assigned a respective neutral telephone number in order to set up a communication connection between subscribers.

19. The method as claimed in claim 18, wherein the neutral telephone numbers are assigned temporarily.

20. An apparatus comprising:

a module configured to one of integrate in a mobile communication appliance or couple via an interface to the mobile communication appliance, the module comprising;

a memory unit for storage of profiles;

a collecting unit that operates using wireless, locally limited network technology, and is configured to collect profiles of subscribers in a communications system;

a correlation unit configured to compare the collected profiles with one another; and

a signaling/synchronization unit.

21. The apparatus as claimed in claim 20, wherein the collecting unit is configured to operate on the basis of at least one of local area network (LAN) and personal area network (PAN) technologies.

22. The apparatus as claimed in claim 20, wherein the memory unit comprises a RAM.

23. The apparatus as claimed in claim 20, wherein the correlation unit comprises a microcomputer.

24. The apparatus as claimed in claim 20, wherein the signaling/synchronization unit comprises a software assisted circuit.
