According to this figure, the system for performing the voice mailbox service providing method of the present invention, a mobile communication network switch for receiving a call request signal from the mobile communication terminal 100 to be the calling party to perform a call connection with the called party 110 and a communication network such as a wired telephone network switch 210 and a mobile communication network switch 110 that provide a communication service to the wired telephone 200 serving as a called party for the call request signal from the mobile communication network switch 110. It includes a voice mailbox service providing server 120 (hereinafter, referred to as a voice mailbox server) that exists and provides a voice mailbox service. In the present invention, the mobile communication network switch 110 and the voice mailbox server exist in the mobile communication network, and the wired telephone network switch 210 exists in the wired telephone communication network.

2 and 3 are flowcharts illustrating a procedure for executing a voice mailbox service method according to the present invention. 2 illustrates a process of storing a voice message when the calling mobile communication terminal cannot immediately make a call connection to the called landline telephone.

First, a call request signal including a telephone number of a communication terminal (hereinafter referred to as a called landline) of a called party through the calling mobile terminal 100 to perform a voice call with the called party. To transmit to the mobile communication network switch 110 (S10).

The mobile communication network switch 110 receiving the call request signal searches for the wired telephone network switch 210 in charge of the communication of the called party's wired telephone 200 and transmits the call request signal (S11).

The wired telephone network switch 210 determines whether the called party's wired telephone 200 can make a call connection in response to the call request signal (S12). That is, when the called party's landline phone 200 is in a call or cannot be connected immediately, such as when the power is off, the flow advances to step S14 to determine that the called party's landline phone 200 is not immediately connected (S14). In addition, when the called party's wired telephone 200 is not immediately incapable of connection, that is, in a call waiting state waiting for a response by the user of the called party's wired telephone 200, the incoming call is transferred from the wired telephone network switch 210. The call request signal is continuously transmitted to the landline 200 at the same time, and the transmission time is measured and compared with a predetermined call connection waiting time (S13). The call connection waiting time is generally set to about 60 seconds, during which the ringback tone sound is output to the calling mobile terminal.

When the call is confirmed by the called party at the called party's landline phone 200 within a call connection waiting time, the wired telephone network exchanger 210 is connected to the called party's mobile communication terminal 100 through the mobile communication network switch 110. The landline 200 is connected to enable the call (S30). However, if there is no response from the called party's landline phone 200 within the call connection waiting time, the process proceeds to step S14 to determine that the called party's landline phone 200 is immediately incapable of connection (S14).

The wired telephone network switch 210 that determines that the called party's wired telephone 200 cannot be immediately connected to the call request signal from the calling mobile terminal 100 transmits a call unavailable notification signal to the mobile communication network switch 110. (S15).

The mobile communication network switch 110, which has received a call impossible notification signal from the wired telephone network switch 210, connects to the voice mailbox server 120 provided in the communication network in which the mobile communication network switch 110 is operated, and then the calling party mobile communication. The terminal 100 is connected to the voice mailbox server 120 (S16).

Accordingly, the voice mailbox server 120 performs a guide on storing a voice message in the calling mobile terminal 100 and records and stores the voice transmitted from the calling mobile terminal 100 (S17). In general, for voice message storage, "To leave a voice message, record after the beep and press * after recording." It is made of a guide broadcast, such as, according to the guide the user will record the call to voice.

First, when the calling mobile terminal 100 records and stores a voice message in the voice mailbox server 120 in step S17, the voice mailbox server 120 receives a voice message arrival notification signal for the recorded voice message. A guide for setting a time and a repetition time to be transmitted to the landline 200 is transmitted to the calling mobile terminal 100 to receive a decision of the calling mobile terminal user (S18). For instructions on these settings, "Please enter two digits each month in the order of the month and day to announce the arrival of a voice message", "Please enter the time to repeat notification in minutes." Or the like.

Thereafter, when the set time is reached, the voice mailbox server 120 transmits a voice message arrival notification signal to the called party's wired telephone 200 (S19).

The voice mailbox server continuously transmits a voice message arrival notification signal and waits for a response to the call connection from the called party's landline phone 200 for a predetermined call connection waiting time (S20).

If there is no response to the voice message arrival notification signal during the call connection waiting time, transmission of the voice message arrival notification signal from the voice mailbox server 120 is stopped (S22), and the time during the interruption is measured. To compare with the repetition time set in the voice mailbox server 120 (S23). When the interrupted time coincides with the set repetition time, the process returns to step S19 to transmit a voice message arrival notification signal back to the called party's landline telephone 200.

When there is a response of the called party's landline phone 200 in step S20 and the call is connected to the voice mailbox server 120, the voice mailbox server 120 receives the voice message stored by the calling party's mobile communication terminal 100. The user of the called party's landline phone 200 can be listened to by transmitting it to the landline phone 200 (S21).

In addition, as described above, the present invention, in addition to the method to be performed after a predetermined call connection waiting time when the called party's landline phone is waiting for a call, a combination of phone numbers including a special number from the calling mobile terminal, eg For example, if you enter '** 23 + phone number', the voice mail service server of the calling party's mobile communication terminal will be connected to the server and save the calling party's voice message. You can also send a notification signal.

As described above, the present invention sets the mobile communication terminal as the calling party communication terminal and the wired telephone as the called party communication terminal, but it can also be used between two mobile communication terminals existing in each communication service network. have. That is, the user of the calling mobile terminal can access the voice mailbox server provided by his communication service provider and store the voice message to the called mobile terminal.

According to the present invention having the above-described configuration, even when a call to a landline telephone without a voice recording function of a called party is attempted through a mobile communication terminal of a calling party, even if a call connection with the called party's landline telephone is not made immediately. The voice message is recorded by using a voice mail service providing server provided in a mobile communication service network of the calling mobile communication terminal, and the voice mail service providing server automatically attempts to connect a call to the called party's landline telephone. By providing a message to a landline telephone, it has an excellent effect of accurately and promptly delivering a caller's call.
