COMMUNICATIONS METHOD IN A COMMUNICATIONS SYSTEM

摘要

The invention relates to a communications method that comprises the step of sending a query message (22) from a central entity (10) to at least one node (K1, K2, . . . , KN). For every queried node, the central entity determines a node-specific time window based on a node-specific response time (T1, T2, . . . , TN). The central entity filters out a response message (A1, A2, . . . , AN, B1, B2, . . . , BN), sent from the queried node, from the signals received during this time window. Based on the node-specific time window (Δ2), the central entity assigns the response message to the queried node. The invention also relates to a computing unit that is configured to operate as a central entity, to a communications system, as well as to a computer program and a computer-readable storage program with said computer program.

1. A communication method in a communication system having a central entity, a plurality of nodes and a shared communication medium, wherein the communication method comprises the following steps that are executed by the central entity:
sending a query message via the shared communication medium to one or more interrogated nodes in the communication system; and, for the interrogated nodes,
determining a node-specific time window on the basis of a node-specific response time;filtering a response message sent by the interrogated node out of signals received during the node-specific time window; andassociating the response message with the interrogated node on the basis of the node-specific time window in each case.
