Method and communication arrangement for establishing a communication link

摘要

A communication link can be established by way of a radio interface between a first mobile communication facility and a second mobile or permanently stationary communication facility. In at least one embodiment, an item of identification information is made available by one of the communication facilities as an optical signal for receipt at the cited sensor; the communication facility, to which the sensor receiving the optical signal belongs, accepts the identification information and transfers the accepted identification information as a request to set up a communication link via the radio interface with the communication facility, which makes or has made the optical signal available. The requested communication facility implements a comparison between the accepted identification information and its own identification information and permits the setup of the communication link as a function of the comparison result.

主权项

1. A method for establishing a communication link via a radio interface between a first communication facility and a second communication facility, wherein a distance between the first and second communication facilities lies in a range in which optical signals are receivable by a sensor associated with at least one of the first and second communication facility, the method comprising:
accepting, at the first communication facility, identification information from the second communication facility, the identification information being transmitted to the first communication facility via an optical signal; transferring the accepted identification information to the second communication facility via the radio interface, as a request to set up the communication link; and establishing the communication link if the second communication facility determines that the transferred identification information received from the first communication facility matches the identification information transmitted to the first communication facility by the second communication facility via the optical signal.
