Messages can be transmitted between a first radio station and a second radio station via a path that runs via one or more additional radio stations. The authorization data is sent such that, while a message is transmitted via the path using radio access technology, at any point in time a subset of adjacent radio stations on the path are authorized to communicate using radio access technology.

Abstract: In a building automation system, a method for automating a building includes a step of acquiring at least one data time history from a sensor or from a meter. The data time history is averaged and the averaged data time history is fitted into at least one occupancy pattern. The occupancy pattern covers a given time span. At least one set point is determined from the occupancy pattern and the at least one set point is fed into a system for heating, ventilation, and/or air-conditioning. In the novel system the at least one data time history is acquired from an element of standard infrastructure.

Abstract: In a method for transferring data packets in a communication network, first data packets having a low priority are transferred between a transmitter and a receiver and second data packets having a high priority compared to the first data packets are preferably transferred between them. In a second data packet to be transferred it is checked whether presently a first data packet is being transferred. If yes, the transfer of the first data packet is interrupted or stopped and the second data packet is then transferred. After the transfer of the second data packet, the transfer of the un-transferred first data packet is repeated or the rest of the incompletely transferred first data packet is transferred. Each first data packet is stored in an intermediate memory in parallel with a transmission and is only deleted from the intermediate memory after complete transfer of the first data packet to the receiver.

Abstract: A method for reconfiguring a communication network is provided. A first network uses a first network protocol and a second network uses a second network protocol, the two networks being connected by two data links. A first data link is initialized as activated and a second data link is initialized as deactivated. A failure of the first data link is detected by a first bridge of the second network, the first bridge being connected to the first data link. A first data packet is generated by the first bridge and is transmitted to a second bridge of the second network, the second bridge being connected to the second data link. The first data packet is received and processed by the second bridge. The first data packet contains information which initiates a partial implementation of the first network protocol on a port of the second bridge and an activation of the second data link.
