The CC 41 is a block in charge of the call processing function of the subscriber using the mobile terminal 10, and transmits the number of the called terminal A provided from the BSC 30 to the NTR 42 to translate the number. . Subsequently, 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 a call register number (callreg_no) and a calling party for distinguishing the calling mobile terminal 10. The CSL 43 is called while setting the analyzed info parameter for the information (whether it is wireless or wired, or whether it is a relay call or a home call).

As the number translation block, the NTR 42 analyzes the number of the called terminal A provided from the CC 41, that is, transmits a report of a wireless intelligent network call (WIN_CALL) to the CC 41.

The CSL 43 is a block in charge of a software library management function for controlling call processing. After being called by the CC 41, the CSL 43 detects and detects a trigger signal for determining whether to perform an intelligent network service. The wireless intelligent network trigger is forwarded to the WSFC 44.

The WSFC 44 is a block that controls the intelligent network triggering for providing the intelligent network service of the mobile subscriber. The WSFC 44 checks the trigger provided by the CSL 43 to check the mobile terminal 10 and the called terminal A. After formatting the number of, the position inquiry information of the called terminal A is transmitted to the LRSC 45.

The LRSC 45 is a block for processing information transmission and reception messages with the HLR 50. The LRSC 45 converts the format information of the called terminal A and the location inquiry information of the called terminal A from the WSFC 44 into the HLR 50. To be sent). In addition, the LRSC 45 requests the announcement broadcast block 46 to send the announcement message that the subscriber is registered in the call blocking service to the mobile terminal 10 according to the service activation code provided from the HLR 50.

Announcement block (46) is a subscriber that is registered in the call blocking service provided from the LRSC (45) (for example, since the called terminal A is registered in the call blocking service, you cannot connect the call path. Message is sent to the mobile terminal 10 via the BSC 30 and the BTS 20.

The HLR 50 determines whether or not the destination terminal A is registered with the service according to the format information of the destination terminal A and the location inquiry information of the destination terminal A provided from the LRSC 45, that is, whether or not the call blocking service is registered. Determining the activation state, if registered and activated, sends a service request message including the ID of the mobile communication switch 40 and the number information of the mobile terminal 10 and the called terminal A to the SCP 60. do. In addition, the HLR 50 receives the service activation code from the SCP 60 and transmits the service activation code to the LRSC 45 in response to the location inquiry information to the LRSC 45.

SCP 60 performs blocking function through call blocking service logic according to service request message provided from HLR 50, loads the result into active code information, and service activation code that service information is reported. To the HLR 50.

A method of implementing a call blocking service in a mobile communication switch according to an embodiment of the present invention having the above-described configuration will be described with reference to the flowchart of FIG. 2.

First, a subscriber (i.e., a subscriber using the terminating terminal A) applies for registration with a telephone station (not shown) to register a private private network and a call blocking service, and the telephone station sends the SCP 60 with the private private network group information and Register the call blocking service (step 200).

As described above, in the state where personal private network group information and call blocking service is registered with the telephone company, any subscriber presses the number of calling and incoming call using the mobile terminal 10 (after the number of the called terminal A), If a call (SEND key is pressed) is requested, the number of the called terminal A is transmitted from the mobile terminal 10 to the BTS 20 (step 201).

The BTS 20 receives the number of the called terminal A from the mobile terminal 10 and then transmits the number to the BSC 30 (step 202).

If the number of the called terminal A provided via the BTS 20 is input, the BSC 30 transmits this number to the CC 41 (step 203).

The CC 41 requests the NTR 42 to translate the number by transmitting the number of the called terminal A provided from the mobile terminal 10 (step 204).

The NTR 42 analyzes according to the number translation request for the called terminal A 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 it is not the trigger signal for the intelligent network service in the check step 206, and transmits a result that is not the intelligent network service to the CC 41 (step 209).

On the other hand, if it is the trigger signal for the intelligent network service in the check step 206, after formatting the number of the mobile terminal 10 and the destination terminal (A), the position inquiry information of the destination terminal (A) in the above-described format The information is carried on the information to the LRSC 45 (step 210).

The LRSC 45 transmits the format information of the called terminal A and the position inquiry information of the called terminal A, provided from the WSFC 44, to the HLR 50 (step 211).

The HLR 50 determines whether or not the destination terminal A is registered with the service according to the format information of the destination terminal A and the location inquiry information of the destination terminal A provided from the LRSC 45, that is, whether or not the call blocking service is registered. The activation state is determined (step 212).

If the call blocking service is not registered and activated in the determination step 212, the call path is controlled by passing the call path to the called terminal A (step 213).

On the other hand, if the call blocking service is registered and activated in the determination step 212, the service including the ID (ID) of the mobile communication switch 40 and the number information of the mobile terminal 10 and the called terminal (A) The request message is sent to SCP 60 (step 214).

SCP 60 performs blocking function through call blocking service logic according to service request message provided from HLR 50, loads the result into active code information, and service activation code that service information is reported. Is sent to the HLR 50 (step 215).

After receiving the service activation code from the SCP 60, the HLR 50 transmits the service activation code to the LRSC 45 in response to the location inquiry information (step 216).

The LRSC 45 is a broadcast announcement that the subscriber is registered in the call blocking service according to the service activation code provided from the HLR 50 (for example, since the called terminal A is registered in the call blocking service, the called terminal A Call is not possible.) A request is made to announcement broadcast block 46 to send a message to mobile terminal 10 (step 217).

The announcement block 46 receives the announcement message from the LRSC 45, then passes through the CC 41 to send the announcement to the mobile terminal 10, and then passes through the BSC 30 and the BTS 20. Is sent to the mobile terminal 10 (step 218).

On the other hand, the mobile communication switch 40 may also send a guide broadcast for the call blocking service to the mobile terminal 10, or switch the call to any destination terminal that can be actually received so that the call path is connected.

Therefore, the present invention provides a call blocking service in a mobile communication switch that provides a call blocking service that has been limited to a public telephone network, even in a mobile communication network, thereby reducing installation costs since it is not necessary to purchase a private exchange to build a private network. In addition, by applying the call blocking function to the mobile communication phone station, the call blocking service function is implemented, which significantly reduces the time to implement the function, and has the effect of maximizing the acquisition of new subscribers.
