Description

METHODO FOR INDICATING RECEIPT OF A MESSAGE AND AUTOMATIC RECALLING TO STORED TELEPHONE NUMBERS}

The present invention relates to a service method of a mobile communication system, and more particularly to an additional service method.

Various types of supplementary services currently used in mobile communication systems provide convenience to users. The mailbox service is one of the above additional services, and is generally used when the called mobile station is in the out of coverage area, the power is turned off, or the user of the mobile station does not receive the call after a certain time. In response, the mailbox device according to the mailbox service receives a call of the calling user instead. This allows the calling user to leave his voice message, text message or contact phone number message in the personal mailbox of the called user (hereinafter referred to as the 'recipient') (the user who left the message in the recipient's personal mailbox). After that, the recipient can call the mailbox device to check the details stored in his or her personal mailbox.

In general, when a subscriber's call message is input from a connected mobile switching center, the mailbox device outputs preset guidance messages through a call formed from the subscriber. The mailbox device analyzes a control message according to a keypad input of a subscriber input through the formed call and performs various services. The service includes a function of storing a message such as a text and a telephone number according to the caller's voice or keypad input in the recipient's personal mailbox. The service also includes the ability to continue calling the recipient's mobile station until the recipient acknowledges the stored message. The service includes a function of outputting the stored message to the recipient when the recipient calls the mailbox device.

The controller 110 controls the overall operation of the mailbox device 100. The line interface unit 120 and the mobile exchanger 140 transmit / receive various messages. The message includes a call message, a control message and a voice message. The line interface unit 120 outputs a call message and a control message output from the control unit 110 to the mobile exchanger 140. The line interface unit 120 outputs a call message and a control message output from the mobile switcher 140 to the controller 110. In addition, under the control of the controller 110, the line interface unit 120 encodes a voice message input from the mobile exchanger and outputs the voice message to the message storage unit 130. In addition, under the control of the controller 110, the line interface 120 decodes the voice message output from the message storage unit 130 and outputs the decoded voice message to the mobile exchanger 140.

The message storage unit 130 includes guide messages and a personal mailbox of each mobile station managed by the mailbox device 100. The personal mailbox stores the caller's call date and time, the call time, the caller's mobile station number, the number of the caller's mailbox device, and the message left by the caller. The message left by the caller may include a phone number (hereinafter referred to as a 'contact phone number') to which the caller can be contacted. That is, the contact phone number may be a phone number other than the caller's mobile station number.

If the control unit 110 stores the sender's message in the recipient personal mailbox provided in the message storage unit 130, the control unit 110 receives the mobile station telephone number corresponding to the recipient's personal mailbox through the line interface unit 120. A control message indicating that the calling message and the caller's message is stored is output to the mobile switch 140. As a result, the mobile switch 140 transmits the messages to the receiver's mobile station via a base station controller (not shown), a base station (not shown), and the like, and attempts to make a call connection with the receiver's mobile station.

2 illustrates a general mobile communication system.

The following describes a conventional mailbox service method of a mobile communication system when a caller makes a call but the receiver's mobile station does not receive the call.

When the caller A makes a call to the receiver B, the call message is sent to the receiver side of the mobile switch 140, the base station controller 270 via the base station 210, the base station controller 220, and the mobile exchange 230 on the sender side. Transmitted to base station 280. However, at this time, if the mobile station of the receiver B is currently in the out of coverage area or the power is turned off or the mobile station does not receive the call even after a certain time, the mobile switch 140 sends the caller A call message to the mailbox device 100. ) As a result, the mailbox device 100 receives a call of the caller B. Then, according to the guidance message of the mailbox device 100, the sender A leaves his message in the recipient B's personal mailbox. At this time, the mailbox device 100 outputs a call message for calling the receiver B to the mobile exchanger (140). At the same time, the mailbox device 100 outputs a message to the mobile switcher 140 indicating that the message is stored in the recipient B's personal mailbox. The message may be a voice message or a text message or the like output to the display unit of the receiver B's mobile station. As a result, the mobile exchange 140 attempts to make a call connection with the mobile station of the receiver B. Thereafter, the recipient B calls the mailbox device 100 to check the message of the sender A stored in his personal mailbox.

As described above, in the mobile communication system, the mailbox device 100 according to the conventional mailbox service stores a message of the caller A or stores a message stored in the receiver B when receiving a call transferred from the mobile switcher 140. Only the operation to send out was performed.

Thus, when caller A leaves a message in recipient B's personal mailbox in an urgent or critical situation, caller A could not know whether recipient B checked the stored message. Therefore, in order to know whether the receiver B acknowledges the message, the sender A has to call the receiver B again. In particular, if the situation described above prevents the receiver B's mobile station from receiving the caller A for a long time, the sender A needs to make repeated calls to the receiver B several times, and the caller A needs to contact the receiver B. There was a hassle and irrationality to wait for the blind.

Meanwhile, the recipient B then calls the mailbox device 100 to check the message of the sender A stored in his personal mailbox. However, at this time, when there is a contact phone number in the message, the recipient B must disconnect the call currently connected to the mailbox device 100 to call the caller A. Then, the recipient B called the contact telephone number. That is, the receiver B has a hassle to input the terminal according to the contact telephone number in order to call the contact telephone number.

Accordingly, it is an object of the present invention to provide a method for automatically calling a caller's contact phone number and a method for notifying the sender of whether a recipient's storage message is checked when the recipient checks his or her personal mailbox.

In order to achieve the above object, a message receiving notification and automatic calling method in a mailbox service of a mobile communication system according to the present invention includes: When a recipient calls a mailbox device to check a stored message, the mailbox device has a contact number in the stored message. A first step of checking whether it is included; A second step of, if the contact telephone number is included, the mailbox device providing an automatic call guide message to the receiver asking the recipient whether or not to automatically call the contact telephone number; In response to the auto call guidance message, when the receiver requests an automatic call of the contact telephone number, the mobile switch connected to the mailbox device calls the contact telephone number while maintaining a call connection with the receiver. 3 courses; A fourth step of providing, by the mailbox apparatus, an acknowledgment message to the recipient, if the contact telephone number is not included, asking the recipient whether or not to notify the sender that the recipient has acknowledged the stored message; When the recipient requests the storage message confirmation notification in response to the acknowledgment guidance message, a mobile exchange connected to the mailbox device notifies the sender that the recipient has confirmed the storage message.

Hereinafter, a description will be given with reference to FIGS. 1 and 2.

When the controller 110 inputs the call message of the receiver B output from the mobile exchanger 140 through the line interface unit 120 in step 310, the controller 110 transmits a mailbox service guide message to the mobile exchanger 140 in step 315. ) In step 320, the controller 110 checks whether the control message by the keypad B of the receiver B is entered into the mailbox management service. If the control message does not enter the mailbox management service, the control unit 110 performs a corresponding function in step 325. If the control message enters the mailbox management service, in step 330, the controller 110 checks whether the control message by the keypad input of the receiver B is the confirmation of the stored message. If the control message is not confirmed in the stored message, the control unit 110 performs the corresponding function in step 335. If the control message is confirmation of the stored message, in step 340, the controller 110 outputs the message stored in the recipient B's personal mailbox to the mobile exchanger 140. In step 345, the controller 110 checks whether the contact message is included in the stored message. If the stored message includes the contact phone number, in step 350, the controller 110 outputs a guide message to the mobile switcher 140 asking whether to automatically call the contact phone number. In step 355, the controller 110 checks whether or not the message of the keypad B of the receiver B is automatically called to the contact telephone number. If the control message by the keypad B input of the receiver B is an automatic call key input, in step 360, the controller 110 maintains a call connected to the receiver B, and transmits the call message corresponding to the contact telephone number to the mobile switcher. 140). When the call is connected to the contact telephone number, the controller 110 notifies the receiver B of this, and connects the call of the receiver B with the contact telephone number.

If the phone number is not included in the stored message in step 345, the controller 110 transmits a guide message to the caller A whether to notify the caller A that the receiver B has confirmed the stored message in step 365. ) In operation 370, the controller 110 determines whether the control message by the keypad B of the receiver B is the stored message confirmation response key. If the control message by the keypad input of the receiver B is the storage message acknowledgment response key input, in step 375, the controller 110 stores the call message and the stored message corresponding to the number of the caller's mailbox device stored in the message storage unit 130. A message corresponding to the acknowledgment is output to the mobile exchanger 140.

In step 360, upon receiving the call message corresponding to the contact telephone number and the control message corresponding to the automatic call from the mailbox device 100, the mobile switch 140 waits for a call to the mobile station of the receiver B to which the current call is connected. Send the message. The mobile switch 140 then sends the call message to the mobile switch or the corresponding switch on the contact telephone number side. The mobile switch 140 then connects the call with the mobile station of the recipient B when the call is connected to the mobile station of the contact phone number or the contact phone number. Thus, the receiver B can automatically call the caller A while the call is connected to the mailbox device 100.

On the other hand, when receiving the control message corresponding to the call message and the storage message confirmation response corresponding to the number of the mailbox device 240 of the caller side from the mailbox device 100 in step 375, the mobile exchanger 140 moves to the caller side. The call message and the control message are sent to the exchange 230. Thus, according to the call message, the mobile exchange 230 transmits a message corresponding to the call message and the storage message acknowledgment response to the caller side mailbox device 240. As a result, the mailbox device 240 performs an operation of notifying the sender A that the receiver B has confirmed the stored message. At this time, the mailbox device 240 may display the confirmation notification in the form of a text message on the display unit of the sender A's mobile station. Therefore, the sender A can know that the receiver B has confirmed the stored message through the display unit.

As described above, the present invention has the advantage that when the receiver calls the mailbox device to check the stored message left by the caller, the receiver can automatically call the contact phone number left by the caller while the call is currently connected with the mailbox device. . In addition, the sender has the advantage that when the receiver confirms the stored message, the sender can know whether the confirmation through the display of the mobile station.
