It supports a plurality of base stations (BTS) 20, 100, and serves as a signal processing function for communication between the base station (BTS) 20, 100 and the mobile switching center (MSC) 40, 80 .

Mobile switching center (MSC) (40) (80) connects a call when a subscriber makes or receives a call, and is connected to a base station controller (BSC) 20 (100) to a mobile communication terminal (MS) 10 ( The call setup and release function of 110 is performed, various functions related to call processing and additional services are performed, and interworking with other networks is performed. The VLR, not shown, is a database that stores information of visited subscribers in the area serviced by the mobile switching center (MSC) 40, 80. The VLR is an area in which it is responsible for preventing frequent HLR (50, 85) inquiry. The mobile communication terminal (MS) 10 (110) and subscriber information registered in the location are retrieved from the HLRs 50 and 85 and temporarily stored.

HLR (50, 85) is a database that stores the permanent information, location information, and additional service information of the mobile communication terminal (MS) (10) (110) and subscribers, MSC (40) (80) to perform various functions related to call processing and supplementary services and to control services. In addition to the basic subscriber authentication (telephone number, ESN authentication) using the HLR (50, 850) as the element responsible for the subscriber authentication, the AC 50, 85 performs accurate subscriber authentication using an authentication key and an authentication algorithm. .

The SMS server 60 delivers an SMS message to the mobile communication terminal (MS) 10 and 110 and stores and manages the message. The VMS server 70 stores and manages the voice mail message and the phone number left to the subscriber.

2 is a flowchart illustrating a method of releasing a selective call rejection of a mobile communication terminal according to an embodiment of the present invention. 1 and 2, the method according to the present embodiment is a method of selectively releasing a call rejection centering on a calling terminal.

First, when a call connection is requested from the calling mobile terminal (MS) 10 to the called mobile terminal (MS) 110, the mobile switching center passes through the base station / base station controller (BTS / BSC) 20, 30. (MSC) the call connection request signal is transmitted to (40) (S10).

Accordingly, the MS 40 determines whether the called number included in the call connection request signal is a terminal for which the Do Not Call Additional Service is applied, and when the called terminal applies for Do Not Add Service as follows. Optionally, the reception rejection is released (S12).

The mobile switching center (MSC) transmits voice mailbox information to the calling mobile terminal (MS) 10 via the VMS server 70, asking whether to select an SMS service for notifying an incoming call. When the SMS service is selected by the calling mobile terminal (MSC) 10 receiving the voice mailbox information, the corresponding SMS service selection information is transmitted through the base station / base station controller (BTS / BSC) 20 and 30 to the MSC. 40). The mobile switching center (MSC) 40 generates an SMS message informing that the incoming call has been received through the SMS server 60 according to the SMS service selection, and the generated SMS message is forwarded to the terminating mobile switching center (MSC) 80 to transmit a base station. The control unit / base station (BSC / BTS) 90, 100 notifies the called party's mobile communication terminal (MS) 110 that an incoming call has been received in an SMS message (S16 to S18).

On the other hand, if the SMS service is not selected by the calling mobile terminal (MS) 10 that receives the voice mail information, the selection information is transmitted through the base station / base station controller (BTS / BSC) 20 and 30. (MSC) 40 is passed. The mobile switching center (MSC) 40 transmits a signal forcibly canceling the call rejection service for the called party number to the called-side mobile switching center (MSC) 80 according to the caller's selection, and to the called-side mobile exchange (MSC) ( 80 temporarily cancels the rejection of the called number and performs the incoming call connection to the called mobile communication terminal (MS) 110 through the base station controller / base station (BSC / BTS) 90, 100. (S20-S22)

3 is a flowchart illustrating a method of releasing a selective call rejection of a mobile communication terminal according to another embodiment of the present invention. 1 and 3 is a method of selectively canceling the call rejection centered on the called terminal according to another embodiment of the present invention.

First, the present embodiment must go through an initial setting (registration process) for selectively canceling a call rejection for a specific caller number in a mobile communication terminal in which the call rejection service is registered before providing the call rejection release service. For example, selectively disabling call rejection for any originating terminal (MS) 10 from any mobile communication terminal (MS) 110 in which a call rejection service is registered to a mobile switching center (MSC) 80. On request, MSC 80 stores information (name, phone number, etc.) for the called-unsubscribe subscriber requested from MS 110 on HLR 85 at the mobile switching center (MSC) 80 Create a list.

Then, when the calling mobile communication terminal (MS) 10 requests a call connection from the called mobile communication terminal (MS) 110, the calling base station / base station controller (BTS / BSC) 20, 30 is connected. The call connection request signal is transmitted to the mobile switching center (MSC) 40 (S32).

The calling party mobile switch (MSC) 40 is connected to the called party mobile switch (MSC) 80 and transmits a call connection request signal. Then, the called party mobile switching center (MSC) 80 searches through the HLR 85 to see if there is a corresponding calling number in the call rejection exception number list registered in S30.

The called party mobile switching center (MSC) 80 determines whether there is a corresponding calling number in the list of the HLR 85 as a result of the search of the HLR 85 (S36).

As a result of the determination in S36, when there is a corresponding calling number in the list of the HLR 85, the called mobile switching center (MSC) 80 temporarily releases the incoming rejection service set in the called terminal and the base station controller / base station (BSC / BTS). (90, 100) performs the incoming call connection to the destination mobile terminal (MS) (110). (S38 ~ S40)

As a result of the determination in S36, when there is no corresponding calling number in the list of the HLR 85, the destination mobile switching center (MSC) 80 generates an SMS message informing that the incoming call has been received through the SMS server 60 and sends the SMS message. The base station controller / base station (BSC / BTS) (90, 100) is sent to the destination mobile terminal (MS) (110) to inform the subscriber that the incoming call has been received by the SMS message (S42).

As described above, the present invention enables unconditional calls in the case of important phone calls by selectively canceling the call forwarding and performing the incoming call connection only according to the caller's choice even during the call rejection service. There is an effect of increasing the convenience of the mobile subscribers.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
