The information is notified (step 216).

IP 60 passes the TLDN parameters assigned TLDN to SCP 50 in accordance with the private number service information provided from SCP 50 (step 217).

SCP 50 receives the TLDN parameters from IP 60 and sends them to NTR 42 in exchange 40 (step 218).

On the other hand, the LRSC 45 receives the intelligent network service number and the digit number for the called terminal B from the SCP 50 and transmits it to the WSFC 44 (step 219).

The WSFC 44 inputs a code (act code (act_code) and term type code) to continuously proceed with call processing using the digit number for the called terminal B provided from the LRSC 45. In step 220, the wireless intelligent network trigger report is transmitted to the CC 41.

The CC 41 transmits the digit number for the terminating terminal B to the NTR 42 in order to perform the call processing to the actual terminating terminal B according to the wireless intelligent network trigger report provided from the WSFC 44 and translates the number. (Step 221).

The NTR 42 analyzes the digit number for the called terminal B required from the CC 41, passes the analyzed result to the CC 41, and immediately outgoing routing to the RCO 46 to obtain routing information. (Step 222).

RCO 46 forwards the call establishment signal to UPC 47 in accordance with the routing request from NTR 46 (step 223).

The UPC 47 controls the call path between the PSTNs (A) to be established according to the call setup signal provided from the RCO 46, so that the call connection is performed to the number-translated destination terminal B (step 224).

Therefore, the present invention provides a personal number service at an exchange that enables a personal number service provided only in a public telephone network to a switching network, thereby providing a personal number service function.
