A method for monitoring an airspace includes a first control and detection system and a second control and detection system. The first control and detection system has a first flying device and a first control and detection unit, and the second control and detection system has a second flying device and a second control and detection unit. An airspace monitoring system is different from the first control and detection unit and also from the second control and detection unit. First data relating to the first flying device is transmitted from the first control and detection unit to the airspace monitoring system, and data based on the first data is transmitted from the airspace monitoring system to the second control and detection unit. In this manner, the method allows a system-independent airspace monitoring process.

An access method for accessing a protected communication service via a public communication network by using a secure communication network, whereby the secure communication network is based on user groups, including defining an access group having access to the communication service based on the user groups of the secure communication network, generating a group key for all members of the access group, providing the group key to a member of the access group via the secure communication network, and accessing the communication service via the public communication network using the group key, is provided. A communication system including 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 implements the above method is further provided.

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.
