Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a block diagram of a call forwarding service system suitable for selecting and providing a voice announcement message to a wired communication terminal according to whether a short message of a forwarded wired communication terminal can be received according to an embodiment of the present invention. 102, first communication network 104, switchboard 106, Home Location Register (HLR) 108, short message service center 110, second terminal 112, second communication network 114 , Third terminal 116 and the like.

Referring to FIG. 1, the first terminal 102 is a wireless mobile communication terminal capable of voice / video call and data communication with the other party through the first communication network 104. When the user inputs a phone number for voice call, etc. The call is generated and transmitted to the exchange 106 through the first communication network 104. When the user inputs a short message and requests transmission, the call is generated through the first communication network 104 by generating a call for the telephone number to be transmitted. Transmit to the exchange 106.

In addition, the first communication network 104 serves to ensure the mobility of the first terminal 102, and includes a base station and a base station controller, and supports both synchronous and asynchronous. Here, in the case of a synchronous wireless communication network, a base station that receives and transmits a wireless communication signal of the first terminal 102 is a base transceiver station (BTS), and a base station controller which controls the base station and performs communication with the exchange 106. A base station controller (BSC), which receives and transmits a radio communication signal of the first terminal 102 in the case of an asynchronous wireless communication network, controls a Node-B and a Node B, thereby switching the switch 106. The base station controller performing communication with the network becomes a Radio Network Controller (RNC).

Of course, the first communication network 104 is not limited thereto, and includes a communication network of all mobile communication systems to be implemented in the future, including a CDMA network, a GSM network other than a W-CDMA network, and a fourth generation.

Next, the exchange 106 processes basic and supplementary services, incoming and outgoing call processing of subscribers, location registration procedure and handover procedure processing of the first terminal 102 and the second terminal 112, interworking with other networks. Function and so on. In addition, ASS (Access Switching Subsystem) for distributed call processing, INS (Interconnection Network Subsystem) for centralized call processing, Central Control Subsystem (CCS) for centralizing operation and maintenance, and mobile subscribers It includes a subsystem, such as a Location Registration Subsystem (LRS) that performs the function of storing and managing information about the.

In addition, the exchange 106 transmits the short message information to the short message service center 110 when the short message is transmitted from the first terminal 102 to the second terminal 112 through the first communication network 104. Request the call forwarding information of the second terminal 112 to the home location register 108 and accordingly register the call forwarding service according to the call forwarding information of the second terminal 112 transmitted from the home location register 108. When the second terminal 112 is registered in the call forwarding service, it is determined whether the short message can be received by the third terminal 116 which has been forwarded according to the call forwarding information. Of course, if the second terminal 112 is a terminal that is not registered in the call forwarding service, the exchange 106 generates a corresponding short message generated and transmitted through the short message service center 110 through the first communication network 104. 2 to the terminal 112.

Subsequently, when the third terminal 116 is able to receive the short message, the switch 106 determines that the short message can be received, and the exchange 106 generates the short message corresponding to the short message generated and transmitted through the short message service center 110. It transmits to the third terminal 116 via the communication network 114.

On the other hand, if the third terminal 116 does not receive the short message, the exchange 106 generates a voice announcement message indicating that the short message transmitted from the first terminal 102 has been received and through the second communication network 114. When the second terminal 112 terminates the call forwarding service, the second terminal 112 forwards the short message generated and transmitted through the short message service center 110. 112 through the first communication network 104.

Here, the present invention has been described as generating a voice announcement message for guiding the reception of a short message in the exchange 106, but the voice announcement message is, for example, an ARS center and voice conversion server connected to the exchange 106. In addition, the voice message may be generated and transmitted through a voice message center capable of generating and transmitting a voice message. In this case, the voice guidance mesh indicating that the text message requested to be transmitted is received and the text message requested to be transmitted are voice converted. Of course, you can send voice messages together.

In addition, the home location register 108 receives the location information of the first terminal 102 and the second terminal 112 and performs functions such as registration recognition, registration deletion, location verification, and the like, and the first terminal 102. And profile information of the second terminal 112 is stored. Here, the profile information refers to subscribed additional service information such as a mobile identification number (MIN), an electronic serial number (ESN), an international mobile subscriber identify (IMSI), and a calling number service.

The home location register 108 may include a subscriber information management device that manages a database of additional service information of a subscriber when implemented in a wired communication service. The home location register 110 for the mobile communication service and the subscriber information management device for the wired communication service perform a function of managing a database of additional service information of the subscriber. In the present invention, call forwarding information for each subscriber (for example, whether wired / wireless service is compatible, call forwarding service is registered, wireless mobile communication terminal number, call forwarding wired communication terminal number, whether to receive a short message of the wired communication terminal, etc. It may be configured to include a call forwarding information database including).

In addition, the home location register 108 checks the call forwarding information of the second terminal 112 requested from the exchange 106, and then transfers the call forwarding information (for example, whether the call forwarding service is registered and the wireless mobile communication terminal number). , Call forwarding wired communication terminal number, whether or not a short message can be received by the forwarded wired communication terminal, etc.) is provided to the exchange 106.

Although not shown, the visitor location register (VLR) stores information of visited subscribers in the area serviced by the switch 106, and registers the location of the first terminal 102 or the first location with the area in charge. 2 The subscriber information of the terminal 112 is taken from the home location register 108 and temporarily stored.

In addition, the short message service center 110 provides a service for transmitting text data (ie, a short message) having a relatively short length of about 80 bytes to 160 bytes, and is transmitted from the exchange 106. A short message corresponding to the related information (eg, calling terminal number, short message data, called terminal number, etc.) of the requested transmission short message is generated and transmitted to the exchange 106.

Next, the second terminal 112 is a terminal capable of voice / video call and data communication with the other party through the first communication network 104, and the first terminal 102 through the exchange 106 and the first communication network 104. To establish a communication service (call call connection) together with a ring signal, and receive a short message from the first terminal 102 through the exchange 106 and the first communication network 104 to The short message is displayed through the program.

On the other hand, when the second terminal 112 registers the call forwarding service and requests the switch 106 to terminate the call forwarding service through the first communication network 104 without receiving a short message, the second terminal 112 requests the call forwarding service from the switch 106. 1 Receives a short message during the forwarded time through the communication network 104 and displays it through a predetermined short message providing program or as a voice message during the forwarded time through the first communication network 104 from the exchange 106. The text guide message converted and transmitted is received and displayed through a predetermined short message providing program.

In addition, the second communication network 114 provides a call service of the wired communication terminal using, for example, a public switched telephone network (PSTN). When a call call connection is requested from the first terminal 102 to the second terminal 112 when the call is forwarded to 116, the call forwarding information generated from the first terminal 102 through the switch 106 is transferred. In response to the third terminal 116 to provide a call service for connecting the call.

In addition, when the third terminal 116 is a terminal capable of receiving a short message, the second communication network 114 transmits a short message transmitted from the exchange 106 to the third terminal 116, and the third terminal 116. When the terminal does not receive the short message, the voice announcement message and the voice message transmitted from the exchange 106 are transmitted to the third terminal 116.

On the other hand, the third terminal 116 is a wired communication terminal connected by wire through the second communication network 114, and when the call is forwarded in response to the second terminal 112, the call from the first terminal 102 is removed. 2 is connected through the communication network 114 to provide a call service with the first terminal (102).

In addition, the third terminal 116 provides a short message transmitted from the first terminal 102 through the second communication network 114 through a predetermined short message program when the short message can be received, and does not receive the short message. If not, the voice prompt message and the voice message transmitted from the first terminal 102 through the second communication network 114 are output as voice.

Therefore, in the call forwarding service system of the present invention, when the wireless mobile communication terminal to which the short message is to be forwarded to the wired communication terminal is determined whether the short message can be received by the wired communication terminal, the short message is determined according to the determination result. By transmitting a voice announcement message indicating that the short message has been transmitted or to the forwarded wired communication terminal, it is possible to provide a call forwarding service in which short message reception is not missed.

On the other hand, in the call forwarding service system as described above, a short message is transmitted from the wireless mobile communication terminal to another wireless mobile communication terminal, and voice guidance is performed according to whether or not the short message can be received by the wired communication terminal which is switched to correspond to another wireless telephone. Although a description has been made of transmitting a message, the first terminal may also transmit a short message to a wireless mobile terminal from various service centers having service telephone numbers (for example, 1588-XXXX, 080-XXXX-XXXX, etc.). Of course, it can be implemented as a call forwarding service system except for 102.

Next, when a short message transmission is requested from the first terminal to the second terminal in the call forwarding service system having the above-described configuration, it is determined whether the call is forwarded through the call forwarding information of the second terminal. After determining whether the communication terminal can receive the short message, a process of selectively providing a voice guidance message for notifying the reception of the short message to the wired communication terminal according to the determination result will be described.

FIG. 2 is a flowchart illustrating a process of selectively providing a voice announcement message to a wired communication terminal according to whether a short message is received by the wired communication terminal which has been forwarded according to an embodiment of the present invention. Hereinafter, the first terminal 102 and the second terminal device 112 will be described as a wireless mobile communication terminal, the third terminal 116 as a wired communication terminal.

2, in the standby mode of the call forwarding service system (step 202), the switch 106 checks whether the transmission of the short message created from the first terminal 102 through the first communication network 104 is requested. (Step 204). Here, the first communication network 104 supports both synchronous and asynchronous, but is not limited to any of the mobile communication systems to be implemented in the future, including a CDMA network, a GSM network other than the W-CDMA network, and the fourth generation. It may include a communication network.

As a result of the check in the step 204, when the transmission of the short message is requested, the exchange 106 transmits to the related information (for example, the calling terminal number, the short message data, the called terminal number, etc.) of the requested short message. Accordingly, various terminal information corresponding to the second terminal 112 to transmit a short message to the home location register 108, in particular, call forwarding information is requested, and call forwarding information transmitted from the home location register 108 (for example, Whether or not a call forwarding service is registered, a wireless mobile communication terminal number, a call forwarding wired communication terminal number, whether or not a short message of the forwarded wired communication terminal can be received, etc.) It is checked whether it is a terminal (step 206).

As a result of the check in step 206, when the second terminal 112 is not a call forwarded terminal, the exchange 106 transmits the related information of the short message requested to be transmitted (for example, the calling terminal number, the short message data, The called terminal number, etc.) is transmitted to the short message service center 110, and the short message service center 110 generates a corresponding short message using the transmitted related information and transmits the short message to the exchange 106 (step 208).

Then, the exchange 106 transmits the short message transmitted from the short message service center 110 to the second terminal 112 corresponding to the called terminal number through the second communication network 104 (step 210). . Thereafter, the second terminal 112 may display the short message transmitted through the first communication network 104 through a predetermined short message providing program.

On the other hand, when the second terminal 112 is a call forwarding terminal as a result of the check in step 206, the switch 106 determines that the second terminal 112 is based on the call forwarding information transmitted from the home location register 108. In step 212, it is checked whether the short message can be received by the third terminal 116 which has been forwarded.

If the third terminal 116 is a terminal capable of receiving a short message as a result of the check in step 212, the exchange 106 transmits the relevant information of the short message requested to be transmitted (for example, the calling terminal number and the short message). Message data, called terminal number, etc.) to the short message service center 110, and the short message service center 110 generates a corresponding short message using the transmitted related information and transmits the short message to the exchange 106. Accordingly, the exchange 106 transmits the short message to the third terminal 116 via the second communication network 114 (step 214). Thereafter, the third terminal 116 may display the short message transmitted through the second communication network 114 through a predetermined short message providing program. Here, the second communication network 114 may include, for example, a wired telephone network (PSTN).

On the other hand, when the third terminal 116 is a terminal that does not receive a short message as a result of the check in the step 212, the exchange 106, the related information of the short message requested to be transmitted (for example, the calling terminal number, In response to the short message data, the called terminal number, etc., a voice guidance message indicating that the short message has been received is generated (step 216). Here, the exchange 106 requests the short message service center 110 to transmit the relevant information of the short message requested to be transmitted to generate a short message, which is sent to the third terminal 116 of the second terminal 112. When the call forwarding ends, the short message is transmitted to the second terminal 112.

The exchange 106 transmits the generated voice announcement message to the third terminal 116 via the second communication network 114 (step 218). Thereafter, the third terminal 116 may receive the voice announcement message transmitted through the second communication network 114 and output the voice guidance message.

On the other hand, the switch 106 checks whether the second terminal 112 requests termination of the call forwarding service to the third terminal 116 (step 220).

As a result of the check in step 220, if the termination of the call forwarding service is requested, the exchange 106 requests the home location register 108 to terminate the call forwarding service of the second terminal 112, and the short message service center ( A short message generated in step 110 is requested, and accordingly, the short message received from the short message service center 110 is transmitted to the second terminal 112 through the first communication network 104 (step 222). Thereafter, the second terminal device 112 may display the short message transmitted through the first communication network 104 through a predetermined short message providing program.

Therefore, according to an embodiment of the present invention as described above, when the destination terminal to which the short message is requested to be transferred is forwarded, and the incoming wired communication terminal does not receive the short message, a voice prompt for notifying the short message is received. By transmitting and providing a message to a wired communication terminal, even if the switched wired communication terminal does not have a short message reception function, it is possible to provide a call forwarding service without receiving a received short message.

Meanwhile, according to an exemplary embodiment of the present invention as described above, a short message is transmitted from another wireless mobile communication terminal to another wireless mobile communication terminal, and the short message may be received by the wired communication terminal which is switched to correspond to another wireless telephone. Although it has been described that the voice announcement message is transmitted, the first message may be transmitted even when the short message is transmitted from the various service centers having the service telephone numbers (for example, 1588-XXXX, 080-XXXX-XXXX, etc.) to the wireless mobile communication terminal. Of course, it may be implemented as a call forwarding service system except for the terminal 102.

Next, when a short message transmission is requested from the first terminal to the second terminal in the call forwarding service system having the above-described configuration, it is determined whether the call is forwarded through the call forwarding information of the second terminal. After determining whether the communication terminal can receive the short message, and based on the determination result, a voice prompt message for notifying the reception of the short message to the wired communication terminal and a voice message corresponding to the short message requested to be transmitted are selectively selected through the voice message center. Describe the process provided.

FIG. 3 is a flowchart illustrating a process of selectively providing a voice announcement message and a voice message to a wired communication terminal according to whether a short message of a call forwarded wired communication terminal can be received according to another embodiment of the present invention. Hereinafter, the first terminal 102 and the second terminal 112 will be described as a wireless mobile communication terminal, the third terminal 116 as a wired communication terminal.

Referring to FIG. 3, in the standby mode of the call forwarding service system (step 302), the switch 106 checks whether the transmission of the short message created from the first terminal 102 through the first communication network 104 is requested. (Step 304). Here, the first communication network 104 supports both synchronous and asynchronous, but is not limited to any of the mobile communication systems to be implemented in the future, including a CDMA network, a GSM network other than the W-CDMA network, and the fourth generation. It may include a communication network.

As a result of the check in the step 304, when the transmission of the short message is requested, the exchange 106 transmits to the relevant information (for example, the calling terminal number, the short message data, the called terminal number, etc.) of the requested short message. Accordingly, various terminal information corresponding to the second terminal 112 to transmit a short message to the home location register 108, in particular, call forwarding information is requested, and call forwarding information transmitted from the home location register 108 (for example, Whether or not a call forwarding service is registered, a wireless mobile communication terminal number, a call forwarding wired communication terminal number, whether or not a short message of the forwarded wired communication terminal can be received, etc.) It is checked whether it is a terminal (step 306).

As a result of the check in step 306, when the second terminal 112 is not a call forwarded terminal, the exchange 106 transmits the related information of the short message requested to be transmitted (for example, the calling terminal number, the short message data, The called terminal number, etc.) is transmitted to the short message service center 110, and the short message service center 110 generates a corresponding short message using the transmitted related information and transmits the short message to the exchange 106 (step 308).

Then, the exchange 106 transmits the short message transmitted from the short message service center 110 to the second terminal 112 corresponding to the called terminal number through the second communication network 104 (step 310). . Thereafter, the second terminal 112 may display the short message transmitted through the first communication network 104 through a predetermined short message providing program.

On the other hand, if the second terminal 112 is a call forwarding terminal as a result of the check in step 306, the switch 106 determines that the second terminal 112 is based on the call forwarding information transmitted from the home location register 108. In step 312, it is checked whether the short message can be received by the third terminal 116 which has been forwarded.

If the third terminal 116 is a terminal capable of receiving a short message as a result of the check in step 312, the exchange 106 transmits the relevant information of the short message requested to be transmitted (for example, the calling terminal number and the short message). Message data, called terminal number, etc.) to the short message service center 110, the short message service center 110 generates a corresponding short message using the related information transmitted, and transmits the short message to the exchange 106, Accordingly, the exchange 106 transmits the short message to the third terminal 116 via the second communication network 114 (step 314). Thereafter, the third terminal 116 may display the short message transmitted through the second communication network 114 through a predetermined short message providing program. Here, the second communication network 114 may include, for example, a wired telephone network (PSTN).

On the other hand, when the third terminal 116 is a terminal that does not receive a short message, as a result of the check in the step 312, the exchange 106 transmits the related information of the short message requested to be transmitted (for example, the calling terminal number, Short message data, called terminal number, etc.) to a voice message center (e.g., ARS center, voice conversion server, etc.) and at the same time, a voice message indicating that a short message has been received and a voice corresponding to the short message requested to be transmitted. In response to the request for generating a message, the voice message center generates a voice prompt message for notifying the reception of the short message and a voice message in which the short message is voice converted according to the related information of the short message requested to be transmitted (step 316). Here, the exchange 106 requests the short message service center 110 to transmit the relevant information of the short message requested to be transmitted to generate a text guide message indicating that the voice message corresponding to the short message has been transmitted. When the incoming call transfer from the second terminal 112 to the third terminal 116 is completed, the short message is sent to the second terminal 112.

The exchange 106 receives the generated voice announcement message and voice message from the voice message center and transmits the voice announcement message to the third terminal 116 via the second communication network 114 (step 318). Thereafter, the third terminal 116 may receive the voice announcement message and the voice message transmitted through the second communication network 114 and output the voice message.

On the other hand, when the second terminal 112 terminates the call forwarding service to the third terminal 116 at the exchange 106, the switch 106 terminates the forwarding service of the second terminal 112 at the home location register 108.
