Abstract

PURPOSE: A method for implementing free phone service in an exchange is provided to accomplish free phone service, such as clover service, 080 service, etc., through a switching network. CONSTITUTION: If a subscriber applies for a personal private network subscription to a telephone office, the telephone office enters personal private network group information in an SCP(Service Control Point)(200). If the subscriber inputs a free phone intelligent network service number and a called terminal number using his mobile terminal while requesting call origination and incoming trunk seizure, a digital number based on the call connection request is transmitted to a BTS(Base station Transceive System)(201). The BTS transmits the call connection signal to a BSC(Base Station Controller)(202). The BSC transmits the call connection signal to a CC(Call Control block)(203). Controlling call switching according to the call origination request and the incoming trunk seizure request, the CC requests an NTR(Number TRanslation block) to translate the free phone intelligent network service number and the called terminal number(204). The NTR analyzes those numbers and transmits a report of a radio intelligent network call(WIN_CALL) to the CC(205). The CC, after receiving the WIN_CALL report, sets a call register number and analyzed information parameters and calls a CSL(Call processing System Library block)(206). The CSL, called by the CC, detects a trigger signal and transfers it to a WSFC(Wireless intelligent network Service Function Control block)(207). The WSFC checks whether the trigger provided from the CSL is a kind of intelligent service(208). In case that the trigger is a kind of intelligent service, the WSFC transfers the free phone intelligent network service number and the called terminal number to an LRSC(Location Register Service Control block)(210).

With reference to the flowchart of Figure 2 will be described a method of implementing the incoming billing service in the exchange according to an embodiment of the present invention having the above configuration.

First, the subscriber must apply to the telephone company to join the private private network. If the subscriber applies to the private network to join the private network, the telephone station registers the private private network group information with SCP (A) (step 200).

As described above, after the personal private network group information is registered with the telephone company, the subscriber requests the call and incoming call occupancy (when passing through another country) using the mobile terminal 10 to use the incoming billing service. If the billing intelligent network service number (e.g., 080) and the destination terminal (C) number 123-4567 are input, the digit number according to the call connection request is transmitted from the mobile terminal 10 to the BTS 20 (step 201). .

The BTS 20 receives the incoming billing intelligent network service number and the called terminal C number according to the call connection signal transmitted from the mobile terminal 10, and transmits it to the BSC 30 (step 202).

The BSC 30 transmits the incoming billing intelligent network service number and the called terminal C number according to the call connection signal to the CC 41 through the BTS 20 (step 203).

The CC 41 controls the call switching (time switching) according to the call request and incoming call occupancy request from the mobile terminal 10, and simultaneously receives the called billing intelligent network service number and the called terminal C number provided by the NTR 42. Request to translate the number (step 204).

The NTR 42 analyzes the incoming billing intelligent network service number and the called terminal C number provided from the CC 41 and transmits a report of the analyzed result, that is, a wireless intelligent network call (WIN_CALL), to the CC 41. (Step 205).

The CC 41 receives a report called a wireless intelligent network call (WIN_CALL) according to the number translation result from the NTR 42, and then the call register number (callreg_no) for distinguishing the calling mobile terminal 10 and the calling subscriber wirelessly. It analyzes whether it is accessed through a network or a wired network, and then calls the CSL 43 while setting an analyzed info parameter analyzing whether it is a relay call or a local call (step). 206).

After being called by the CC 41, the CSL 43 detects a trigger signal for determining whether to perform an intelligent network service and forwards the detected wireless intelligent network trigger to the WSFC 44 (step 207).

WSFC 44 checks the trigger provided from CSL 43 (step 208).

If the trigger signal in the check step 206 is not the type of intelligent network service, a result is transmitted to the CC 41 that it is not the type of intelligent network service (step 209).

On the other hand, if the trigger signal in the check step 206 is the type of intelligent network service, the called billing intelligent network service number and the called terminal C number for the intelligent network service are transmitted to the LRSC 45 (step 210).

The LRSC 45 forwards the billing intelligent network service number and the called terminal C number provided from the WSFC 44 to the SCP (A) (step 211). Then, SCP (A) analyzes the chargeable intelligent network service number and the called terminal (C) number provided from the LRSC (45) and converts it into a corresponding number, and converts the digit number for the converted called terminal (C) into LRSC ( 45) (step 212).

The LRSC 45 receives the digit number for the called terminal C analyzed for the called billing intelligent network service number and the called terminal C number from the SCP (A) and transmits it to the WSFC 44 (step 213).

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 C provided from the LRSC 45. In step 214, the wireless intelligent network trigger report is transmitted to the CC 41.

The CC 41 transmits the digit number for the called terminal C to the NTR 42 to perform the call processing to the actual called terminal C according to the wireless intelligent network trigger report provided from the WSFC 44 to translate the number. (Step 215).
