Abstract

In a common channel signaling network which includes a plurality of signaling points or point codes connected to each other by signaling data links, a routing message is received from a remote signaling point via a signaling data link and translated into availability states and congestion levels of a message transfer controller and a signaling subsystem controller part and stored into a point code status memory. 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.
