Method for processing data in a packet-switched wireless communication network, having a plurality of network nodes (N1, N2,..., N6, FW) between which data packets are transmitted, with which method: - the information contained in one or more data packets received in one or more network nodes (N1, N2,..., N6, FW) is at least partially extracted from said packets; - one or more physical transmission parameters of the received data packet(s) are ascertained, wherein the physical transmission parameter(s) specifies/specify or is/are dependent on one or more characteristics of the physical transmission of the received data packet(s); - the received data packet(s) is/are filtered on the basis of a set of rules that take at least a part of the extracted information and at least a part of the physical transmission parameter(s) into account and processed further as a function of the filtering process, wherein the data packets received in one or more network nodes (N1, N2,..., N6, FW) include configuration-data packets transmitted within the scope of a predefined configuration process, wherein one or more network nodes (N1, N2,..., N6, FW) is/are configured through the predefined configuration process, wherein a measure of confidence therein is ascertained on the basis of one or more ascertained physical transmission parameters of the received configuration-data packet(s), which measure indicates the confidence that the received configuration-data packet(s) belong(s) to the predefined configuration process, wherein the configuration process is cancelled or interrupted if the measure of confidence represents a degree of confidence that is less than or less than or equal to a predefined minimum confidence, wherein a predefined configuration process is initiated by one or more first configuration-data packets transmitted having a first signal strength by one or more network nodes (N1, N2,..., N6, FW), wherein network nodes (N1, N2,..., N6, FW) that receive said first configuration-data packets do not launch any further configuration processes, wherein the predefined configuration process is performed using one or more second configuration-data packets transmitted having a second signal strength less than the first signal strength by one or more network nodes (N1, N2,..., N6, FW). - the information contained in one or more data packets received in one or more network nodes (N1, N2,..., N6, FW) is at least partially extracted from said packets; - one or more physical transmission parameters of the received data packet(s) are ascertained, wherein the physical transmission parameter(s) specifies/specify or is/are dependent on one or more characteristics of the physical transmission of the received data packet(s); - the received data packet(s) is/are filtered on the basis of a set of rules that take at least a part of the extracted information and at least a part of the physical transmission parameter(s) into account and processed further as a function of the filtering process, wherein the data packets received in one or more network nodes (N1, N2,..., N6, FW) include configuration-data packets transmitted within the scope of a predefined configuration process, wherein one or more network nodes (N1, N2,..., N6, FW) is/are configured through the predefined configuration process, wherein a measure of confidence therein is ascertained on the basis of one or more ascertained physical transmission parameters of the received configuration-data packet(s), which measure indicates the confidence that the received configuration-data packet(s) belong(s) to the predefined configuration process, wherein the configuration process is cancelled or interrupted if the measure of confidence represents a degree of confidence that is less than or less than or equal to a predefined minimum confidence, wherein a predefined configuration process is initiated by one or more first configuration-data packets transmitted having a first signal strength by one or more network nodes (N1, N2,..., N6, FW), wherein network nodes (N1, N2,..., N6, FW) that receive said first configuration-data packets do not launch any further configuration processes, wherein the predefined configuration process is performed using one or more second configuration-data packets transmitted having a second signal strength less than the first signal strength by one or more network nodes (N1, N2,..., N6, FW).
