| 摘要 |
The invention is related to a digital, wired or wireless, communication system constituting a network of multiple nodes. The network comprises a central node. The central node controls all the communication in the network. In such a system, information related to the system itself or to the nodes in the system can be distributed by the central node among the peripheral nodes in the network or kept in a database in the central node, which database is accessible on request from the peripheral nodes in the network. The information can be conveyed to the central node from the peripheral nodes, either commanded by the central node itself or on request from a peripheral node, triggered by an internal event in the peripheral node, e.g. a change of state having external consequences. The invention provides a mechanism for efficient distribution of relevant information in such a system.
