A composite state of a point code is derived from the stored availability states and congestion levels to create a local database. In accordance with the composite state of a point code, the routing of signaling messages to that point code is controlled. In response to a request, the composite state of a point code of the network is reported to the requesting user. The composite states of the code points are constantly monitored. When a change occurs, a new composite state is broadcast to all users. | |
