It is a system that wirelessly connects a call between each mobile subscriber or a general public switched telephone network (PSTN). Recently, the demand is increasing rapidly.

In the general mobile phone system, various additional services are provided for the convenience of the user. Among these various additional services, a message transmission service function such as voice message or numeric message such as text message and telephone number is provided to a plurality of subscribers. In addition, the voice message service function of each of the above-described additional services is performed when the terminal of the mobile subscriber is turned off or when the subscriber is located in an area where call connection is impossible, that is, when the terminal of the subscriber cannot be recognized by the mobile telephone system. This function is provided to allow the user to leave a voice message.

In such a conventional mobile phone system, if any caller (including a non-mobile phone service subscriber) performs dialing to any subscriber (recipient) subscribed to the mobile phone service through a mobile phone network or a public payphone network, the mobile phone service The server system of the mobile telephone provider that provides the call attempts to access the call through the base station in which the subscriber (called party) corresponding to the dialed number is located in response to a call request signal transmitted through the mobile telephone network or a general public telephone network.

At this time, if the location of the called party is not registered from each base station or the called party's terminal is turned off, the server system transmits a voice message to the caller and informs the caller that the called party is in a disabled state. Will be performed. Then, when the caller records the voice message to be sent to the called party using the voice message service function, the server system stores the recorded voice message in a storage means provided in the system.

Through the above-described process, the mobile telephone system receives a voice message for a certain subscriber and the subscriber is called in a state where the subscriber can make a call or the terminal is powered on, and from any base station among a plurality of base stations, When the subscriber's location is registered, the server system transmits message reception information informing that the voice message has been received through the base station.

In addition, the mobile subscriber can access the server system through his terminal to receive the transmitted voice message and then listen to his voice message through a predetermined subscriber verification (password verification) process.

On the other hand, in the conventional method of transmitting a voice message of the conventional mobile phone system, when the subscriber wants to listen to the transmitted voice message later, there is an inconvenience of having to reconnect with the server system every time. In order to rehearse the received voice message, it is inconvenient for the subscriber to be located in an area where mobile phone service is available.

Therefore, the present invention is made in the light of the above, the mobile phone system converts the voice message received to the subscriber in the form of a data stream and transmits to each subscriber, each subscriber has their own voice message It is an object of the present invention to provide a method for transmitting a voice message of a mobile telephone system capable of receiving and storing a terminal.

In order to achieve the above object, the present invention provides a voice message transmission of a mobile telephone system including a mobile telephone operator system for connecting a call with the plurality of terminals in response to a call connection request signal received from a plurality of terminals and an external telephone network.

Allows you to listen to the message.

2A and 2B are flowcharts illustrating a process of transmitting a voice message in a mobile telephone system according to a preferred embodiment of the present invention. First, a series of the server 100 system of the mobile telephone operator described above with reference to FIG. 2A will be described. The process of described in detail as follows.

While the overall operation of the server 100 included in the mobile telephone system configured as shown in FIG. 1 is operating in a standby state, a call connection with any mobile telephone subscriber (called party) is required through a public public telephone network and a wireless telephone network. When a signal for inputting is input, the server 100 retrieves the location information of the called party and whether or not the recipient can be received from a home location register (not shown). In the impossible state, the first controller 110 switches the overall operation of the server 100 to the voice message service mode (step 201).

When the voice message for transmitting the public public telephone network and the wireless telephone network to the called party is received again (step 203), the first controller 110 transmits the received voice message through the A / D converter 140 to the digital data stream. After conversion to (step 205), the converted digital data stream is stored in the first storage unit 150 (step 207).

Through this process, the voice message received from the outside is converted into a digital data stream and stored therein, and the overall operation of the server 100 is switched to the standby mode (step 211), and the voice received in step 203 described above. When the location information of the subscriber (the called party) corresponding to the message is registered by the base station 130 or the current state of the subscriber is switched to the state where voice telephone service is available (step 211), the first control unit 110 sends a voice to the subscriber. After transmitting the voice message reception information indicating that the message has been received through the base station 130 (step 213), it is switched back to the standby mode state (step 215).

When the request signal requesting the transmission of the voice message received from the terminal 200 on the subscriber side is received through the base station 130 (step 217), the first controller 110 performs a predetermined subscriber confirmation process (eg, For example, after the password verification process, the voice message in the form of a digital data stream stored in the first storage unit 150 is extracted (step 219) and transmitted to the terminal of the subscriber through the base station 130 (step 219). 221).

Accordingly, the subscriber can receive and store the voice message received by the user using the terminal 200. FIG. 2B shows a terminal of the subscriber side during a voice message transmission process in the mobile telephone system according to the preferred embodiment of the present invention. As a flowchart illustrating an overall operation process for the 200, it will be described with reference to the drawings.

When the overall operation of the subscriber-side terminal 200 is in the standby mode (step 251), when the data transmitting and receiving unit 220 receives information indicating that the voice message has been received through the base station 130 of the server 100 (step 253). In response to this, the second control unit 210 notifies the user by displaying the fact that the voice message has been received through the display means (not shown) (step 255).

When a key signal for receiving a voice message received by a user's operation is input from a key input unit (not shown) (step 257), the second controller 210 controls the server 100 through the data transceiver 220. ), A voice message transmission request signal is generated (step 259). In this case, when the voice message in the form of a digital data stream is received from the server 100 through the data transceiver 220 in response to the voice message transmission request signal (step 261), the second controller 210 receives the received digital data stream. That is, after storing the voice message in the second storage unit 230 (step 263), the overall operation of the terminal 200 is switched to the standby mode state (step 265).

In the state described above, the voice message received to the mobile subscriber is transmitted from the server 100 in the form of a digital data stream and stored in the terminal 200, and outputs the stored voice message again by a user's operation. When the key signal is input (step 267), the second control unit 210 extracts the digital data stream (voice message data) stored in the second storage unit 230 in response to the input key signal to convert the D / A unit. By converting to analog data through 240 and outputting through the voice output unit 250 (step 250), the subscriber can listen to the received voice message.

The subscriber can rehearse at any time without accessing the server 100 of the mobile telephone system unless the voice message in the form of a digital data stream stored in his terminal is deleted.

As described above, according to the present invention, in the mobile telephone system, each subscriber receives a voice message transmitted to his terminal and stores it in his terminal, and then, if he wants to listen to it, the subscriber does not have access to the server system. Since it is possible to rehearse at any time using only its own terminal, there is an effect that can satisfy the needs of a wider variety of users, thereby providing an improved mobile phone service.
