The present invention further relates to a communication system comprising a secure communication network based on user groups, a public communication network, a protected communication service, and an access server for managing access rights to the communication service, whereby the communication system is adapted to execute the above method.
摘要:
Monitoring data transmissions in a telecommunication network between a service user computer belonging to a service user and a service computer. A service request message from the service user computer prompts an intermediate node in the telecommunication network, which intermediate node is arranged between the service user computer and the service computer providing the requested service, to transmit an intermediate-node service request message to the service computer. The intermediate node then receives a service message from the service computer, which service message includes user data for the requested service and a service use parameter associated with the service, and the intermediate node reads the service use parameter from the service message and transmits it to a central parameter storage system in the telecommunication network. The parameter storage system stores the service use parameter on a user related basis, and the intermediate node transmits the user data to the service user computer.

An approach warning system includes at least one marking module and a warning module. The at least one marking module comprises a marking module transmission unit configured to emit electromagnetic signals, and a motion detector configured to detect a motion. The at least one marking module is configured to emit presence signals as the electromagnetic signals when a motion is detected. The warning module comprises a reception unit configured to receive the electromagnetic signals emitted by the at least one marking module, and an output device configured to emit an approach warning. The warning module is configured to emit the approach warning via the output device dependent on a reception of the presence signals emitted by the at least one marking module.
摘要:
The present invention relates to a method for detecting and warning against wrong-way drivers, the method comprising the following steps: a) establishing a radio field over a roadway section to be monitored and at least substantially transversely to a predetermined correct driving direction of the roadway section, the radio field having at least two radio field sections that are spaced apart when viewed in the driving direction and have associated reception field strengths; b) detecting attenuations of the reception field strengths of the radio field sections that occur due to radio shadowing during driving through the roadway section; c) determining the sequence of the radio field sections in which an attenuation of the respectively associated reception field strengths has been detected; d) comparing the determined attenuation sequence with the correct driving direction; and e) initiating at least one warning signal if the attenuation sequence runs opposite to the correct driving direction.
