The present invention can simply deliver the message to be delivered to a large number of people in real time in the form of voice, a voice message service method that can provide a message service at a low cost by utilizing existing network resources without the addition of equipment and It relates to a mobile communication system applying this.

In general, mobile communication services include cellular phones, personal digital phones (PDAs), IMT-2000 terminals (International Mobile Telecommunication-2000), and GSM (Global System for Mobile communication) terminals. Through the communication terminal, a service that enables a voice call to a mobile subscriber regardless of the location and time, and with the recent development of mobile communication technology, the price of the mobile communication terminal and the mobile communication service usage fee becomes cheap, The utilization rate of the service is increasing regardless of age or gender, and the demand is expected to increase further.

As the use of the mobile communication service increases as described above, in order to facilitate the user, various additional services using the mobile communication system have been developed and provided.

General additional services currently provided in addition to the voice call service in the mobile communication service are, for example, a message service performing a text or multimedia message transmission service, and a location based service providing various application services based on location inquiry / tracking. For example, a download service for downloading content / software to a mobile communication terminal, and a voice mail service for storing and managing a voice message to be delivered to the called party when the called party is in a disabled state.

FIG. 1 schematically illustrates a general mobile communication system, and the existing mobile communication system is basically an infrastructure for connecting a wireless voice call channel, and is responsible for wireless connection to each mobile communication terminal 11a and 11b. No. 7 for connecting a plurality of base stations 12a and 12b, a plurality of exchanges 13a and 13b connected to the plurality of base stations 12a and 12b and performing a call exchange, and a plurality of exchanges 13a and 13b. A voice mail server provided with a mobile network 14 and providing a voice mail service to a called party when a voice memo is left when a call is not made with a called party as a means for providing an additional service. 15), a short message service system (hereinafter referred to as SMSC) 16 that provides a text message service, and a message that provides a broadcast service of a short message. The mobile broadcasting terminal (Cell Broadcasting Message Center, CBMC) 17, and a large amount of data such as pictures and music that can not be transmitted by a short message service (SMS) at a time through a wireless data channel ( A long message service system (hereinafter referred to as LMSC) for transmitting to 11a and 11b).

The non-explained reference numeral 19 denotes a PDSN for performing call processing for a wireless data service. In FIG. 1, the LMSC 18 is connected with a wireless network of the base stations 12a and 12b to transmit a long message. . In addition, in the following description, for convenience of description, the mobile communication terminals 11a and 11b, the base stations 12a and 12b, and the exchanges 13a and 13b exchange a message or a call with a calling party that sends a message or a call. The call is divided into the called party.

In the above configuration, the voice mailbox service provided through the VMS 15, although the calling terminal 11a requests a call connection to the called terminal 11b, power off or disconnection from the called terminal 11b or other circumstances If a call is not made with the called party, the call is connected between the calling terminal 11a and the VMS 15, and if the caller leaves a voice message that the caller wants to be delivered to, the voice message is stored in the VMS 15. In addition, the receiving terminal 11b is informed of the fact that the voice message is stored, and the receiving terminal 11b that has confirmed this is connected to the VMS 15 to listen to the voice message stored in the VMS 15. At this time, since the VMS 15 manages the voice message for each of the called subscribers, the same voice message cannot be transmitted to more than one called party, and the called party accesses the VMS 15 to listen to the notified voice message. Since the call cost is generated, the process of listening to a message is inconvenient, and the voice message listening rate is low.

In addition, the text message service provided through the SMSC 16 generates a text message by manipulating a button of the caller originating terminal 11a, and then requests a message to be sent, and then the originating base station 12a and the originating exchange 13a. The request is transmitted to the SMSC 16 via the SMSC 16, and the SMSC 16 checks whether the terminating terminal 11b is in a receiveable state and transmits the corresponding text message to the terminating terminal 11b when the receiving terminal 11b is in a receiving state. do. In this case, the called party can check the contents of the received message by text by selecting the corresponding message from the inbox provided through the user interface of the called terminal 11b. However, the text message service has a disadvantage in that a text message writing method is different for each manufacturer of a mobile communication terminal, and there are many button operations for writing a text message and it is complicated. There is a problem that is low.

In addition, in the case of the multimedia message service provided through the LMSC 18, the message writing method is basically the same as the short message service method, and only the multimedia files such as a long text, a picture, a picture, a video, and a music are included thereon. As a result of the transmission, it is still used only in some layers, and the transmission target is limited to long text messages and multimedia files such as pictures, pictures, videos, and music.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned conventional problems, and an object thereof is to provide a voice message service method and a mobile communication system using the same, which can deliver a message of the same content to one or more mobile communication subscribers in real time in a simple manner.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same reference numerals are used for parts having similar functions and functions throughout the drawings.

2 is a flowchart illustrating a voice message service procedure according to the present invention.

Referring to Figure 2, the voice message service procedure through the mobile communication system according to the present invention will be described. The following procedure is performed by a server providing a voice message service according to the present invention (hereinafter referred to as a voice message server).

First, the voice message service according to the present invention is started by receiving a voice message transmission request from a voice service user (S101). In this case, the service user requesting the voice message transmission may be a mobile communication subscriber or an information provider who wants to provide predetermined information or advertisements to a plurality of mobile communication subscribers through this service.

Having received the voice message transmission request, the voice message server creates a voice message to be delivered through interaction with the service user (S103). For example, when the service user is a mobile subscriber, a voice call is created by connecting a call to the mobile communication terminal and receiving and storing the voice message of the service user through the call. In addition, it may additionally provide background music of the voice message. In addition, the service user may create a voice message in advance, and then transmit the voice message to a voice message server in a file form.

When the voice message is created as described above, the called party who receives the created voice message is selected (S105). More specifically, the telephone number of the called terminal, that is, the called party's mobile station identification number (MIN) is received. In this case, there may be more than one called party receiving the voice message.

In addition, in order to check whether a service can be provided to the inputted party, a mobile communication system, in particular, an AAA server providing authentication, authorization, and accounting functions for user access processing and service provision. Requests and receives the information of the recipients (S107). At this time, the information of the called party to be transmitted includes, for example, information on the mobile communication terminal model of the called party and the mobile communication service providing state (pause) of the called party.

As described above, when the called party information is obtained, it is determined based on this whether the called party is serviceable and whether the format of the delivered voice message file should be converted (S109 and S113). That is, if the called number is in a paused state, since service provision is not possible, it is determined that the service is not available. In addition, in order to transmit a voice file in the CDMA network, the voice file must be converted into a QCELP file. No conversion is required. Therefore, when the receiver's mobile communication terminal model is a CDMA terminal, it is determined that the format conversion of the file is necessary.

As a result of the determination, when the called party is not available for service, it ends after notifying the service user who requests the voice message transmission whether or not the service is available or the reason for no service, regardless of format conversion (S111).

In another case, if the called party is available for service and a format conversion is necessary, the format of the created voice message is converted into a designated format (for example, a QCELP file) (S115).

As described above, a long message server of a mobile communication system that performs a multimedia message transmission service through a wireless data channel after the media format conversion is performed or as a result of the determination, when the called party is serviceable and does not need format conversion. A message service center (hereinafter referred to as LMSC) is requested to transmit the voice message (S117).

In response to the request, the LMSC automatically downloads the voice message directly to the called terminal. This procedure is the same as the existing multimedia message transmitting procedure performed by the LMSC. In brief, the LMSC connects the called terminal to the wireless data channel. To this end, a text message server for transmitting a text message of a mobile communication system, more specifically, a short message server (hereinafter referred to as SMSC) or a cell broadcasting message server (hereinafter referred to as CBMC) In conjunction with, and transmits an incoming notification short message indicating that there is a message to download to the called terminal, and when the called terminal accesses the LMSC request for withdrawal, the voice message is pushed to the called terminal in the push (Push) method Download automatically.

The voice message server according to the present invention receives the transmission result for the corresponding voice message from the LMSC performing the above-described procedure (S119), and informs the service user who has requested the voice message transmission of the received transmission result, so that the service user knows. (S121).

3 is a schematic structural diagram of a mobile communication system provided with the voice message service of the present invention described above.

Referring to Fig. 3, the present invention relates to an originating / receiving terminal 11a, 11b, an originating / receiving base station 12a, 12b, an originating / receiving exchanger 13a, 13b, a mobile network 14, and an SMSC. In the existing mobile communication system including the (16), the CBMC (17), the LMSC (18), and the PDSN (19), the mobile terminal (14) is connected to the exchanges (13a, 13b) to the calling terminal ( And a voice message server 20 for receiving the voice message request from 11a) and the voice message to be forwarded and for transmitting the voice message over the LMSC 18 over a wireless data channel.

The originating / receiving terminals 11a and 11b are mobile communication terminals of mobile communication subscribers using the voice message service provided by the present invention, and distinguish a calling party for transmitting a voice message and a called party for receiving a voice message, respectively. It is shown.

The originating / receiving base stations 12a and 12b are in charge of radio access to the originating / receiving terminals 11a and 11b, respectively, and the originating / receiving exchanges 13a and 13b communicate with the originating / receiving base stations 12a and 12b. Connected, and performs voice call exchange.

The SMSC 16 and the CBMC 17 provide a text message service and a text message broadcast service to the calling / receiving terminals 11a and 11b, and receive a voice message at the request of the LMSC 18. In step 11b, the incoming notification short message for the voice message is transmitted.

The LMSC 18 requests the SMSC 16 or the CBMC 17 to transmit an incoming notification short message to the called terminal 11b according to the message transmission request from the voice message server 20 according to the present invention. When the wireless data channel is connected from the destination terminal 11b by the notification, and the message withdrawal is requested, the voice message file is downloaded to the destination terminal 11b in a push manner.

In addition, the mobile communication system may provide content such as background music so that a content DB server 21 may be connected to the voice message server 20 through an IP network to provide various effects when creating a voice message. .

In addition, the mobile communication system is a device of a corresponding information provider (hereinafter, referred to as an information providing device) such that an information provider in the field of advertising or language service can deliver advertising or language information by voice through a voice message according to the present invention. 22 may be connected, and the information providing device 22 may be connected to the voice message server 20 through an IP network. The connection method between the information providing device 22 and the voice message server 20 is not limited thereto, and may be changed in various forms according to the network structure.

In addition, in FIG. 3, reference numeral 23 denotes an AAA server that performs authentication, authorization, and charging for the mobile communication service in the mobile communication system.

4 and 5 are detailed flowcharts showing specific implementation examples of a voice message service based on the aforementioned mobile communication system.

First, FIG. 4 is a signal flowchart illustrating a process of providing a voice message service to a mobile subscriber by applying the voice message service method according to the present invention.

Referring to FIG. 3, a service is requested by accessing a voice message server 20 from a mobile terminal (hereinafter referred to as an originating terminal) 11a of a mobile communication subscriber who wants to use a voice message service (S201). More specifically, pressing a specific menu button (for example, a menu button for creating a voice message) prepared in advance on the calling terminal 11a, or a designated service number (for example, * 77 or representative number 200-1234). When a call is requested by pressing)), a call requesting the voice message service is transmitted to the calling exchange 12a, which sends the voice message service from the called number (* 77 or 200-1234) of the received call. It determines that the call is related, and routes the incoming call to the voice message server 20.

By the above, when the calling terminal 11a and the voice message server 20 are connected, the calling subscriber creates a voice message according to the ARS guidance or the designated order provided from the voice message server 20 (S202). The created voice message is transmitted from the calling terminal 11a to the voice message server 20 and stored. The composition of the voice message includes a recording process of a voice message to be delivered and a process of selecting a mobile terminal number (hereinafter referred to as called number) of a called party to which the voice message is to be delivered, wherein the called number is one or more. Can be specified.

In addition, the calling subscriber may designate background music, a background picture, or the like when delivering a voice message. In this case, the voice message server 20 works in conjunction with a content DB server 21 for storing various types of contents (background music or photos, etc.) that can be transmitted together with the voice message during the voice message creation process (S202). If the calling subscriber selects the background music or the picture, the caller receives the selectable content file by accessing the content DB server 21 (S203). In this case, the content DB server 21 may be configured by a mobile communication provider and configured in a mobile communication system, or may be provided by a content provider (CP) outside the mobile communication system.

In addition, the voice message server 20 transmits the called subscriber information for each called number to the AAA server 22 in order to confirm availability of the called number selected by the calling subscriber in the voice message creation process (S203). For example, information about the terminal model, pause information, etc.) is requested and received (S204).

Based on the forwarded called subscriber information, first, it is checked whether the called number is serviceable (S205). For example, in the paused state, service becomes impossible. As a result of the checking, when the called party is unable to service, the called terminal 11a may notify the service impossible (S206).

In addition, on the basis of the delivered called subscriber information, it is checked whether media conversion is necessary (S207). More specifically, it is checked whether or not media conversion is performed based on the terminal model of the called number. As a result of the confirmation, if format conversion is necessary, the media (i.e., voice message, etc.) is converted into a designated format, and then the media, voice message and background music or photo are combined, and if no format conversion is necessary, These messages are combined to form a voice message (S207 to S209). For example, in the case of a CDMA terminal, the voice file must be converted into a QCELP file, whereas in the case of a W-CDMA network, it is not necessary to convert the voice file into another format. The processes S204 to S209 are performed for all called numbers when the called number is one or more.

When the voice message configuration is completed as described above, the voice message server 20 requests the transmission of the voice message composed of the LMSC 18, and receives a response to the request (S210).

Thereafter, a long message delivery procedure is performed by the LMSC 18, so that the voice message is transmitted to the destination terminal 11b, and more specifically, the LMSC 18 performs authentication for the called party. After inquiring to the AAA server 22 and receiving the receiving subscriber authentication information (S211), the SMSC 16 requests the incoming notification short message for the push of the voice message to the authenticated receiving subscriber. (S212), the SMSC 16 obtains the actual location information of the called party and transmits an incoming notification short message to the called terminal 11b, and the receiving terminal 11b receiving the incoming notification short message is When the incoming notification short message is received, the voice message withdrawal is requested to the LMSC 18, the voice message is withdrawn, and if the withdrawal is successful, the voice message acknowledgment is transmitted to the LMSC 18 (S214). The voice message withdrawal process refers to a process of downloading a voice message file in a push manner by automatically connecting the wireless Internet to the LMSC 18 in a state where the customer does not recognize. That is, the delivery of the voice message to the destination terminal 11b is made through a traffic channel through the wireless Internet.

By the above procedure, by receiving the voice message reception confirmation transmitted from the destination terminal 11b, the LMSC 18 confirms whether the transmission is successful to the called party with respect to the voice message requested to be transmitted, and confirms the transmission result. Notify the voice message server 20 (S215). At this time, if the called terminal 11b does not normally retrieve the voice message, the LMSC 18 repeats from step S212 so that the voice message delivery to the called terminal 11b is successful. At this time, the number of repetitions or the repetition period may be arbitrarily set by the operator. However, if the receiving terminal 11b does not receive the voice message even after the designated number or time has elapsed, the voice message is discarded and the voice message server 20 is notified of the discard.

In addition, the LMSC 18 notifies the originating terminal 11a of the result of the successful transmission of the voice message to the terminating terminal 11b (S216).

On the other hand, the destination terminal 11b is completed downloading of the voice message file, which is stored in the message box of the terminal (generally, a message box for storing a text or voice message is implemented in the terminal), and thus the called subscriber Checks the message by listening to the received voice message by opening the corresponding box (S217). At this time, since the voice message is transmitted in the form of a file and stored in the terminal, the voice message can be listened to as the file is reproduced as it is without having to access a voice message server. The called subscriber can then choose whether to delete the message or store it permanently and re-edit the voice message stored on the terminal or send it to another subscriber or message / homepage.

As described above, when the called subscriber confirms the received voice message, a reception confirmation message is transmitted from the called terminal 11b to the LMSC 18, which is then delivered to the calling terminal 11a so that the calling subscriber receives the called subscriber's message. You can see whether the message is checked.

Voice message service according to the present invention, in addition to the terminal-to-terminal service shown in FIG. 4, voice advertising message transmission in the advertising field considering Biz marketing, language information in the education field, news (in the field of information provision) Broadcasting, newspaper), etc.

5 is a flowchart illustrating a process of providing an advertisement or information through a voice message according to another embodiment of the present invention.

Referring to FIG. 5, an information provider who wants to provide information to an unspecified or specific plurality of mobile communication subscribers through a voice message service makes information (advertisement, language, news, etc.) to be provided in a voice message format (S301). The voice message server 31 is provided to the voice message server 31 through the information providing device 30 (S302). The information providing apparatus 30 is a means for transmitting a voice message by accessing the voice message server 31 on the information provider side, and may be connected to the voice message server 31 through, for example, an IP network.

In this case, when the voice message is transmitted to the voice message server 31, the recipient may designate and transfer the corresponding subscriber to the corresponding information, and the recipient may not be separately designated.

If the information provider does not separately designate the called subscriber, the voice message server 31 manages the subscriber information management DB 32 which manages setting information of additional services such as whether the subscriber receives the information and the type of information to be received. Inquiry to the service information of the called subscriber to receive the information of the called subscriber set to receive the information, and if the called subscriber is designated, it is determined whether the designated called number meets the service conditions. 32) and receives the inquiry (S305).

When the called subscriber is selected by the above, the voice message server 31 requests and receives the information of the called subscribers from the AAA server 33 (S305), and based on the information, whether the called party is available or not. It is checked whether or not the music file is converted (S306, S308). In the above, the called party notifies the information providing apparatus 30 that the service is not available for the called number that is not available for service (S307), and if the format conversion is required, such as a CDMA terminal, among the serviceable called numbers, the corresponding voice file. Is converted to a QCELP file (S309). On the other hand, as described above, the W-CDMA terminal does not need a separate format conversion.

When the voice message to be transmitted is prepared by the above, the voice message server 31 transfers the converted voice message to the LMSC 18 and requests transmission to the destination terminal 11b (S310). In this case, by designating a plurality of destination numbers, voice messages with the same contents can be sent to several people at the same time.

When the LMSC 18 receives the request of the voice message server 31, the LMSC 18 first queries the AAA server 22 to receive authentication information about the called subscriber who has delivered the corresponding voice message (S311). In addition, in order to push a voice message to the authenticated called party, the SMSC 16 requests an incoming notification short message to be sent (S312).

In response to the request, the SMSC 16 obtains the location information (eg, the destination exchange information) of the actual terminal through the HLR (not shown), and calls the destination terminal 11b based on the location information. When the incoming short message is received and the incoming call is successful, the called terminal 11b transmits a response message to the short message incoming message to the SMSC 16 (S313).

In addition, when the called terminal short message is received as described above, the called terminal 11b accesses the LMSC 18 while not knowing the corresponding mobile communication subscriber, requests a withdrawal of the voice message, and requests the LMSC ( 18) when the voice message file is downloaded by the push method and the download of the voice message file is completed, the reception result is included in the reception confirmation message and transmitted to the LMSC (S314).

After the LMSC 18 downloads the voice message file and receives an acknowledgment message, the LMSC 18 sends the voice message to the voice message server 31 based on the reception result of the called terminal 11b included in the acknowledgment message. Notifies the transmission result of the (S315), the voice message server 31 transmits the received transmission result notification to the information providing device 30 (S316).

In the process, if the destination terminal 11b does not normally withdraw the voice message, the LMSC 18 recognizes that the withdrawal failure of the destination terminal 11b through the voice message reception confirmation delivered in step S314 Retransmission may be performed by performing step S312 again according to the set condition, and in this case, the number or time of retransmission may be set. If retransmission is requested within the set condition, but voice message retrieval still fails, the LMSC 18 discards the voice message file, and voice message server (S315) indicates that voice message delivery has failed. 31), the voice message server 31 transmits the transmission result to the information providing apparatus 30, thereby notifying that the voice message service was not successful.

By the above, the information provider requesting the voice message service can confirm the processing status of the requested voice message service by confirming the received transmission result notification.

On the other hand, when the downloading of the voice message file is successfully completed, the called terminal 11b notifies the terminal through the user interface according to the designated format that the voice message has been received, and recognizes that the new subscriber receives the new voice message. If you want to listen to the stored voice message, you can open the designated message box (refer to the user interface for storing text or multimedia messages in the terminal) and select the message to play the stored voice message file and listen to it immediately.

Thereafter, the voice message may be deleted or permanently stored at the destination of the called subscriber. In addition, the stored voice message may be re-edited on the terminal or transmitted to another subscriber or homepage as it is.

According to the above, the present invention can provide a message service that can be easily used by any calling subscriber who is not familiar with the text message transmission method that requires inputting and transmitting text by operating a button on the terminal. In this case, it is possible to check the delivered voice message without accessing an additional voice and video mailbox without connecting a communication channel, thereby reducing call charges and increasing customer convenience.

In addition, the present invention can send a voice message written by the calling subscriber to several people at the same time, the voice message received by the called subscriber to send again to several people, re-edited to send it as its own message or send it to the homepage, etc. Because the transmission is possible, a variety of mobile subscribers can be utilized, which can further increase sales and satisfy various needs of customers.

In addition, the present invention can use a wireless data channel with less usage than a saturated wireless voice channel when delivering the voice message to the called party from the operator side, and because the voice message file is stored directly in the terminal, such as a voice mailbox service There is no need to store or manage voice messages for each subscriber for a long time. As a result, it is possible to use existing network resources and facilities without adding new network resources, thereby reducing the investment cost. .

In addition, the present invention can be used not only for the voice message transfer between subscribers, but also in a variety of fields such as advertising or information providing field as a customer service method, thereby providing various services through a mobile communication terminal.
