Abstract: The invention relates to a roaming method for an electrical charging system with at least two subsystems. In the method, a charging data set is received through a communication module of a gateway device from a charging station assigned to the gateway device. The charging data set is forwarded by a peer-to-peer module assigned to the gateway device to a peer-to-peer application of a peer-to-peer network, and a roaming action is controlled by a roaming controlling means of the peer-to-peer application executed by at least a part of the nodes of the peer-to-peer network based on the received charging data set.

Abstract: A raw material and/or recycling system, including at least one tagging unit configured to provide at least one recyclable material element with at least one identifier. The system also includes at least one first peer-to-peer module assigned to the tagging unit and at least one peer-to-peer network having at least one peer-to-peer application. The first peer-to-peer module is configured to provide the provided identifier and at least one status parameter data set related to the recyclable material element to the peer-to-peer application. The peer-to-peer application includes at least one registering means executable upon provision of the provided identifier by at least a part of the nodes of the peer-to-peer network. The registering means is configured to register at least the recyclable material element by storing at least the provided identifier and the provided status parameter data set in at least one registry storage.
