PURPOSE: To remarkably reduce the number of in-network signals by providing a table storing information acquired through collation to management information of other node to a transfer source and selecting and storing the information based on the frequency of collation and the history. CONSTITUTION: In the case of collation to a service control node SCPu, a data storage node MDSx configures routine collation requests in plural boxes as one signal for each node SCPi and sends the signal to a node SCPu. Each node SCPu expands the collation requests and collates a routing number RNi based on subscriber data and configures acknowledge signals of the acquired RNi as one signal and sends the signal to the node MDSx. In this case, the node MDSx updates the recording information of an MDS routing number reference table Tx based on the routing number collation frequency and the reference history of the boxes. Then the information with higher probability designated in a destination is stored with high priority. |
