3 is a block diagram illustrating another embodiment of the configuration of a voice message server (VIMS) according to the present invention.

In the present embodiment, the voice message server 400 connects to the calling terminal through the mobile communication network 300, records the voice signal transmitted by the calling terminal, and sets the voice message. The recorded voice message is transmitted to the called terminal according to the called terminal information transmitted from the calling terminal. The configuration is as follows.

Referring to FIG. 3, the VIMS 400 according to the present invention includes a control unit 410 for controlling the overall operation, a network connection unit 420 for connecting to the mobile communication network 300, and a voice to the connected mobile communication terminal. ARS provider 431 for performing guidance and ARS database 432 for storing voice guidance information, a user manager 441 for storing / managing user information in user information database 442, and ARS provider The voice message recording unit 450 for recording the voice transmitted from the calling terminal according to the voice guidance through the 431 and the voice message recorded through the voice message recording unit 450 are stored in the voice message database 462. Or a voice message management unit 461 for transmitting a voice message stored in the voice message database 462 to a called terminal, and for generating a short message and transmitting the short message through the mobile communication network 300. SMS control unit 470 is included.

The VIMS 400 according to the present invention having the above-described configuration receives / records the voice transmitted from the calling terminal through the mobile communication network 300 and transmits the received voice to the called terminal.

When the calling terminal 100 transmits to the called terminal 200, the mobile communication network 300 connects the call to the called terminal, but the called terminal 200 cannot make a call connection (for example, the called terminal). Power off, no answer, busy, etc.), the mobile communication network 300 switches the call of the calling terminal to the VIMS 400.

When the call is switched, the VIM 400 extracts data for voice guidance stored in the ARS database 432 through the ARS provider 431 and performs voice guidance for a voice message to the calling terminal.

Accordingly, the calling terminal user selects a voice recording menu according to the voice guidance from the ARS provider 431 and inputs a voice through a microphone. The voice input by the user is transmitted to the VIMS 400 via the mobile communication network through the calling terminal, and the ARS provider 431 of the VIMS 400 sends the voice message transmitted from the calling terminal to the voice message recording unit 450. To pass.

The voice message recording unit 450 records the voice from the calling terminal, converts it into a predetermined format, and stores the voice message in the voice message database 462 under the control of the voice message manager 461.

After the voice recording, the calling terminal transmits the mobile telephone number of the mobile communication terminal, that is, the called terminal, to which the voice message is to be delivered, and the voice message manager 461 matches the called number with the recorded voice message. At this time, it is natural that the calling number information can be matched with the recorded voice message.

Thereafter, the voice message manager 461 monitors the state of the called terminal through the mobile communication network 300. For example, the voice message manager 461 may monitor the state of the called terminal through the HLR or the MSC.

As a result of the monitoring, when the called terminal is in a callable state, the mobile communication network 300 requests a call connection to the called terminal corresponding to the called number, for example, the mobile communication terminal 200.

Accordingly, the MSC 240 of the mobile communication network 300 obtains route information of the called terminal through the HLR 250 in order to connect a call to the mobile communication terminal 200 corresponding to the called number, that is, the called terminal. . The MSC 240 requests a call connection to the called terminal according to the obtained route information. The MSC 240 may transmit the information indicating the voice message to the called terminal when the call connection request, and may transmit the calling number to the called terminal according to the caller information display.

The called terminal outputs a predetermined ringtone in response to a call connection request from the MSC 240. In this case, the called terminal may display information indicating that the current call is a voice message on the display unit or may display the calling number.

When the called terminal responds to the call connection request, the voice message manager 461 of the VIMS 400 reproduces the voice message stored in the voice message database 462 and transmits the received voice message to the called terminal through the mobile communication network 300. do. Accordingly, the called terminal outputs the voice message transmitted from the VIMS 400 through the speaker so that the user of the called terminal can listen to the voice message.

On the other hand, the VIMS 400 may transmit the data of the voice message to the called terminal in a data pushing method, and the voice message manager 461 performs a data push request to the called terminal corresponding to the called number to the mobile communication network 300. In addition, the mobile communication network 300 pushes voice message data to the called terminal according to the data push request. The called terminal receives and stores a voice message and displays a message informing the arrival of the voice message on the display unit. Accordingly, the user can listen to the stored voice message.

In the above voice message delivery operation, when the called terminal is in a state in which it is impossible to deliver the voice message normally, such as power off, no answer, or busy, the VIMS 400 performs a call on the receiving terminal through a mobile communication network, for example, an HLR or an MSC. Monitors the status and delivers a voice message when it becomes accessible.

The VIMS 400 may generate a short message including a voice message transmission situation through the SMS controller 470 and transmit the short message to the calling terminal.

4A and 4B are flowcharts illustrating an embodiment of a voice message transmission process according to the present invention.

4A and 4B, the calling terminal 100 transmits to the called terminal 200 (S10), and the calling MSC sends a path to the called terminal 200 to the HLR 250 according to the calling request. Perform the request (S21).

The HLR 250 requests the route information to the called MSC according to the route request in step S21 (S22), and the called MSC transmits a response message including the route information to the HLR 250 (S23). In response, the HLR 250 transmits a response message including the route information to the originating MS (S24).

The originating MSC determines whether the called terminal 200 is in an unreceivable state, for example, a power off or a busy state, according to the information provided from the HLR 250 (S30). At this time, if the called terminal is determined to be incapable of switching the current call to VIMS (400) (S40).

However, if it is determined in step S30 that the call is not incapable, the calling MSC sets up the call to the called MSC according to the route information (S31), and the called MSC performs paging to the called terminal (S32). It is then determined whether the called terminal responds to paging (S33). When the called terminal 200 answers in step S33, a call path may be established between the calling terminal 100 and the called terminal 200 to perform a call (S34).

However, if the terminating terminal 200 does not respond to paging at step S33, that is, if the terminating terminal is unresponsive, the terminating MSC switches the current call to the VIMS 400 (S35).

In addition, when a call transfer is made in step S35 or step S40, a call is established between the calling terminal 100 and the VIMS 400 (S50).

According to the call setup in step S50, the ARS provider 431 of the VIMS 400 extracts data for voice guidance stored in the ARS database 432 (S61) and performs voice guidance to the calling terminal 100. (S62).

Accordingly, the calling terminal user selects a voice recording menu according to the voice guidance from the ARS provider 431 and inputs a voice through a microphone. The voice input by the user is transmitted to the VIMS 400 via the mobile communication network through the calling terminal (S71), and the ARS providing unit 431 of the VIMS 400 receives the voice transmitted from the calling terminal. Forward to 450.

The voice message recording unit 450 records the voice from the calling terminal, converts it into a predetermined format, and stores the voice message in the voice message database 462 under the control of the voice message manager 461 (S72).

After the voice recording, the calling terminal 100 transmits the mobile telephone number of the mobile communication terminal, that is, the called terminal 200, to transmit the voice message (S81), and the voice message manager 461 records the called number. The voice message is generated by matching the message (S82). In this case, the called number may be provided from the MSC that performed the call transfer. It is also natural that the calling number information can be matched to the recorded voice message.

The voice message manager 461 requests the route information of the called terminal 200 from the HLR 250 to query the location information of the called terminal 200 (S91). In response to the route information request, the HLR 250 requests and receives route information from the corresponding exchange, that is, the destination MSC (S92). The HLR 250 transmits the received route information to the VIMS 400 (S93).

The voice message manager 461 of the VIMS 400 determines whether the corresponding called terminal 200 is in a callable state according to the route information received in step S93 (S100). In this embodiment, the VIMS 400 monitors the status of the called terminal through the HLR 250, but may monitor the status of the called terminal through another configuration of the MSC or the mobile communication network.

When it is determined that the called terminal is in a callable state in step S100, an incoming call to the called terminal 200 is requested to the called MSC (S111). Accordingly, the incoming MSC performs paging to the called terminal 200 (S112). In this case, the called MSC may transmit information indicating that the voice message is a paging message to the called terminal according to the transmission information from the voice message manager 461, and may transmit the calling number to the called terminal according to the indication of the calling party information.

When the called terminal 200 responds to the paging (S113), the call setup between the VIMS 400 and the called terminal 200 is made (S120), the voice message management unit 461 of the VIMS 400 is a voice message database The voice message stored in the 462 is reproduced and transmitted to the called terminal 200 (S130).

Accordingly, the called terminal user can listen to the voice message only by answering the call without additional operation.

In this case, although not shown, if the called terminal is not answered in step S112, the VIMS 400 performs paging again after a predetermined time elapses.

The present invention described above, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all aspects.
