Abstract

PURPOSE: A method for notifying a messaging waiting in a mobile communication system is provided to quickly listen to a voice message by transmitting a PIP tone in a call processing block of an MSC(Mobile Switching Center) and informing a mobile subscriber that the voice message waits in a VMS(Voice Mail System) when the mobile subscriber originates or terminates a call. CONSTITUTION: If a random subscriber records a voice message to be transmitted to a mobile subscriber having a VMS function in a VMS, the VMS informs the record of the voice message to a VLR(Visitor Location Register) block of an MSC in which the position of the mobile subscriber is registered through a location register(S10). If the mobile subscriber is in a call origination state(S20), a call processing block of the MSC requests information of an origination subscriber to the VLR block and confirms information of the origination subscriber(S30). If the voice message left to the mobile subscriber exists(S31), the call processing block of the MSC transmits a PIP tone to the mobile subscriber(S32), informs that the voice message is in standby state in the VMS, and performs a call setup(S33). If the mobile subscriber is in a call termination state, the call processing block of the MSC requests information of a termination subscriber and confirms information of the termination subscriber(S40). If the voice message left to the mobile subscriber exists(S41), the call processing block of the MSC completes the call setup of origination and termination sides and transmits a ring signal to the mobile subscriber(S42). If the termination-side mobile subscriber answers to the transmitted ring signal, the call processing block of the MSC disconnects the ring signal, transmits the PIP tone to the mobile subscriber(S43), and informs that the voice message is in standby state in the VMS for performing a telephone call(S44).

If the mobile subscriber is in a call origination state, the call processing block of the switching station is transferred from the call processing block of the switching station to the VLR block. If a voice message left to the mobile subscriber exists as a result of the calling subscriber information verification step of requesting and confirming outgoing subscriber information and the verification of the outgoing subscriber information, the call processing block of the switching center transmits a pip tone to the mobile subscriber and transmits a VMS. Know that there is a voice message waiting for you to listen to After the PIP tone transmission and call setup step for performing the call setup process and the voice message recording step, if the mobile subscriber is in a call receiving state, requesting and confirming the subscriber information from the call processing block of the switching center to the VLR block is performed. If there is a voice message left to the mobile subscriber as a result of the checking of the called party information and the checking of the called party information, the ring signal is sent to the called mobile subscriber after the call processing block in the call processing block of the switching center is completed. If the called mobile subscriber responds according to the transmitted ring signal, the receiver disconnects the ring signal and sends a pip tone to the mobile subscriber to inform the VMS that an unlistened voice message is waiting. It is characterized in that it comprises a pip tone sending and performing a call performing step.

Hereinafter, a message waiting notification method of a mobile communication system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a mobile communication system according to the present invention, and includes a plurality of mobile subscribers 10 moving in an unspecified area, and a base station 20 for transmitting and receiving a message and managing radio resources with the mobile subscriber 10. And a control station 30 that controls the base station 20 and transmits and receives a message with the base station 20, performs a switching role in conjunction with the control station 30, another station, and another network, and performs a call processing block. Switching station 40 for transmitting a pip tone when there is a voice message not listening to a mobile subscriber having a VMS function, and a location register connected to the switching station 40 to register and manage the location of the mobile subscriber 10. 50, and a VMS 60, which is connected to the switching center 40 to store and transmit voice messages for performing the VMS function.

The message waiting notification method of the present invention made in the mobile communication system configured as described above will be described with reference to the flowchart of FIG. 2.

First, in the voice message recording step S10, if any mobile subscriber 10 tries to make a call by calling a mobile subscriber 15 having a VMS function, the mobile subscriber 15 is absent or another mobile subscriber. If it is in a call with (17) and cannot make a call, the voice message to be delivered to the mobile subscriber 15 is recorded and left in the VMS 60.

That is, only the mobile subscriber 15 having the VMS function can receive the corresponding VMS service.

At this time, when the mobile subscriber 10 leaves the voice message to be delivered to the mobile subscriber 15 having the VMS function in the VMS 60 in the voice message recording step (S10), the VMS 60 registers it with the location register 50. And the location register 50 again informs the VLR block of the switching center 40 where the mobile subscriber 15 whose location has been left is registered.

After the voice message recording step (S10) proceeds to the step of determining the call origination and call reception of the mobile subscriber (S20) to determine whether the mobile subscriber (15) having the VMS function is in the call origination or call reception state, If the call originating state, the process proceeds to the calling party subscriber information checking step (S30), and if the call incoming state proceeds to the called party information verification step (S40), respectively.

In step S30, the mobile subscriber having the VMS function attempts to call, i.e., transmits a signal to the base station 20, the control station 30, and the switching center 40 as the originating subscriber information is checked. From the call processing block of the switching center 40, the calling subscriber information is requested from the call processing block to the VLR block, that is, the information of the mobile subscriber 15 having the VMS function.

That is, in the voice message recording step S10, the VMS 60 informs the mobile subscriber 15 that the voice message has been delivered to the VLR block of the switching center 40 through the location register 50, so that the call processing is performed. The block can confirm the presence of a voice message by checking the information of the mobile subscriber 15 from the VLR block.

If there is a voice message left to the mobile subscriber 15 from the outgoing subscriber information confirmed in the outgoing subscriber information checking step S30 after the outgoing subscriber information checking step S30, the process proceeds to the step of determining whether there is a voice message. Proceeding to the pip tone sending step (S32), the call processing block of the switching center 40 transmits a pip tone to the mobile subscriber 15 so that the voice message not listening to the VMS 60 is waiting. Inform).

As a result of the determination of the presence or absence of the voice message (S31), the voice message left to the mobile subscriber 15 from the calling subscriber information confirmed in the calling subscriber information checking step S30 does not exist or the pip tone sending step ( After S32) to proceed to the call setup step (S33) to proceed to the call setup process.

At this time, when the next corresponding signal is received during the call setup process as described above, the pip tone transmission is stopped and the pip tone transmission period is set to be within 0.5 seconds.

Thereafter, the mobile subscriber 15 who hears the pip tone confirms that the voice message delivered to him is waiting in the VMS 60, and uses the VMS 60 to listen to the voice message that has not been heard yet.

In the receiving subscriber information confirming step (S40), if any mobile subscriber 17 attempts to make a call to the mobile subscriber 15 having the VMS function, the switching station is configured to set up the called party to the mobile subscriber 15. The call processing block 40 requests the called subscriber information, that is, the information of the mobile subscriber 15, from the call processing block to the VLR block to confirm the called subscriber information.

That is, if any mobile subscriber 17 attempts to make a call to mobile subscriber 15 having a VMS function, an outgoing call setup is made, and the called mobile subscriber 15 is in a state where a call is possible. Paging is sent to know the position of 15. At this time, when the called mobile subscriber 15 responds to paging, the called party is set up.

Here, since the VMS 60 in the voice message recording step S10 informs the mobile subscriber 15 that the voice message has been delivered to the VLR block of the switching center 40 through the location register 50, the call is received. The processing block may check the information of the mobile subscriber 15 from the VLR block to confirm the presence of a voice message.

If there is a voice message left to the mobile subscriber 15 from the called party information confirmed in the called party information check step (S40) after the step of checking the called party information (S40). Proceeding to the call setup and ring transmission step (S42), the call setup is completed, the call setup is completed, and after the call setup is completed, a ring signal is transmitted to the called party's mobile subscriber 15.

After the call setup and ring transmission step S42, the process proceeds to the pip tone transmission step S43, and the call processing block of the switching center 40 moves in and out according to the ring signal transmitted in the call setup and ring transmission step S42. If the subscriber 15 responds, the ring signal is disconnected, and then a pip tone is sent to the mobile subscriber 15, and the call proceeds to step S44 to make a call.

As a result of the determination of the presence or absence of the voice message (S41), if there is no voice message left to the mobile subscriber 15 from the called party information confirmed in the called party information checking step (S40), a call setup and ring transmission step ( S45) and then completes the call setup after the call setup, and then sends a ring signal to the called party's mobile subscriber 15 and proceeds to the direct call execution step (S44) to allow the call to be made. .

Thereafter, the mobile subscriber 15 who hears the pip tone confirms that the voice message delivered to him is waiting in the VMS 60, and uses the VMS 60 to listen to the voice message that has not been listened to yet.

On the other hand, after the mobile subscriber 15 listens to all the voice messages, the VMS 60 notifies the location register 50 of the switching center 40, and the location register 50 again detects that the mobile subscriber 15 is located. The registered exchange office 40 is notified of this.

The message waiting notification function of the present invention as described above is a service not provided in the existing PSTN, and is an exchange service of a mobile communication system braked to a mobile subscriber having a VMS function.

As described above, according to the present invention, when a mobile subscriber having a VMS function makes or receives a call in a call processing block in an exchange, there is a voice message that does not listen to the VMS by sending a pip tone to the mobile subscriber. By allowing the user to listen to the voice message, the mobile subscriber can quickly and easily check the voice message stored in the VMS without having to check the voice message.
