ース５Ａを介して行われる。The network signal routing situation in the managed signal network is simulated based on the signal routing information in 3C and 3D and the operational status of the signal link set. This simulation detects signal loop routing phenomena within the network and unroutable destinations. When a signal loop routing phenomenon is detected, the test system 5G is activated if necessary, and a loop routing abnormality confirmation test (for example, MTP specified in CCITT recommendation 0.795) is performed.
Routing Verification Test (MRVT)) is performed, and if an abnormality is confirmed, the network traffic control processing 5H instructs the signal relay point performing the abnormal routing to request to stop the routing, or each signal relay point 3A, 3B, 3C, and 3D, requests the network configuration modifier 11M (eg, invoking a Forward Forbidden (TFP) procedure) to perform alternate routing for 3A, 3B, 3C, and 3D. Furthermore, if necessary, the maintenance personnel will instruct the signal relay points 3A, 3.
A request to change signal routing information, etc. is made to nodes B, 3C, and 3D through node relay information change management processing 5E. The interface with the maintenance person is performed via the man-machine interface 5A.

The load status of the entire signaling network is monitored based on data indicating the throughput and system efficiency data of each signal relay node and the load status collected by (2), and network congestion is predicted. If a danger of a congestion state is detected as a result, a network traffic control process 5H requests a signal point within the network to activate a congestion control procedure (for example, a transfer control procedure (TFC)). In addition, an operation status display system 5C is prepared to notify maintenance personnel of the network operation status. The network management control protocol interface 5J controls message formats and procedures for exchanging information with each signal relay point.

This has the effect of enabling the necessary control. In addition, since it is managed as a network as a whole,
Concerning congestion control, this also has the effect of enabling synchronized and effective control of all nodes at once.
