Abstract
The invention concerns a network comprising an interconnecting network and several network nodes that are coupled to said interconnecting network and are designed to adapt their local communication time schedule to the communication time schedule of at least one other network mode, prior to being integrated as active network nodes. A network node to be integrated checks the activity of other network nodes and if no activity is identified, sends out positional messages for other network nodes, said message being fixed by predetermination in its communication time schedule. If a network node cannot be integrated as a reference node, it can only be integrated as an active node if it adapts its local communication time schedule to that of the reference node after receiving positional messages and if a check as to whether its own communication time schedule agrees with the communication time schedules of at least some of the active network nodes proves positive.

9. A network system, the system comprising:
-
an interconnecting network;
a reference network node communicating with said interconnecting network, said reference node having a reference node communication time schedule; and
a plurality of network nodes coupled to said interconnecting network, said network nodes each being adapted, before integration as an active network node, for adjustment of a local communication time schedule to a communication time schedule of at least one other network node, wherein a network node to be integrated is adapted to test activity of other network nodes and, in case of no activity, is assigned as said reference network node with fixed transmission of predetermined position messages for said other network nodes, wherein each network node is adapted to receive position messages for adjustment of its local communication time schedule to said reference node communication time schedule and, in case of a positive result of an agreement check between said local communication time schedule and communication time schedules of at least part of active network nodes, is integrated as an active network node. - View Dependent Claims (10, 11, 12, 13, 14)

15. A network node in a network system, the system having:
-
an interconnecting network;
a reference network node communicating with said interconnecting network, said reference node having a reference node communication time schedule; and
a plurality of network nodes coupled to said interconnecting network, said network nodes each being adapted, before integration as an active network node, for adjustment of a local communication time schedule to a communication time schedule of at least one other network node, wherein a network node to be integrated is adapted to test activity of other network nodes and, in case of no activity, is assigned as said reference network node for fixed transmission of predetermined position messages for other network nodes, wherein a network node is adapted for integration as an active network node after receipt of position messages for adjustment of said local communication time schedule to said reference node communication time schedule and in case of positive result of an agreement check between said local communication time schedule and communication time schedules of at least part of active network nodes.

16. A method for integrating a network node as an active network node in a network system, the network system having a reference network node and an interconnecting network for connecting together a plurality of network nodes and the reference network node, the method comprising the steps of:
-
a) testing activity of other network nodes;
b) if no activity is detected in step a), transmitting position messages predetermined in a communication time schedule for other network nodes;
c) if activity is detected in step a), adjusting a local communication time schedule to that of a reference network node based on receipt of position messages;
d) testing for agreement between the local communication time schedule and communication time schedules of at least part of active network nodes; and
e) integrating into the network system as an active network node if step d) yields a positive result.
