The present invention relates to voice message delivery in a mobile communication system, and more particularly, to a voice message management system and method of a mobile communication system capable of delivering a voice message through an e-mail server instead of a BMS device.

Conventionally, a mobile communication system transmits a voice message using a VMS (Voice Messaging System) device, where VMS is an additional device of an exchange station, and when a call fails through an exchange station in conjunction with an exchange station, the voice message is transmitted. A system that stores and sends messages.

1 is a block diagram illustrating a voice message transmission using VMS in a conventional mobile communication system.

As shown in the drawing, a mobile communication system using a conventional VMS includes a terminal which is a mobile station capable of accessing the Internet through a swap server; A base station for controlling a call to the terminal; A control station controlling the base station; An exchange station for controlling a call between the control station and a public switched telephone network; VMS which is a voice message transmission device; IWF, which is an interworking device between voice network and Internet network; A swap server serving as an interface for accessing the Internet through a terminal; A public switched telephone network providing a telephone exchange service; It consists of the internet network which is the connection network of data communication

The terminals 10a and 10b are terminals that are currently in service and are capable of accessing the Internet through a wireless application protocol (WAP) server 70a or 70b.

Here, the WAP (WAP) servers 70a and 70b are server systems that serve as interfaces required for the terminal itself to access the Internet network.

A base station (BTS) base station (substation transceiver subsystem) 20a, 20b is located between a mobile station (MS) 10a, 10b and a control station (BSC, base station controller) 30a, 30b. Call control and maintenance functions.

That is, the mobile stations 10a and 10b first recognize the base stations 20a and 20b and provide necessary data, allocate traffic channels to call requests, and open call paths.

The control stations (BSCs) 30a and 30b are located between the base stations 20a and 20b and the switching stations 40a and 40b to manage and control the base stations 20a and 20b.

That is, it controls the call set up through the base stations 20a and 20b that are in charge and performs maintenance functions in the base stations 20a and 20b and the control stations 30a and 30b.

A mobile switching center (MSC) 40a, 40b is located between the control stations 30a, 30b and the public switched telephone network (PSTN) 80 to control the call.

IWF (InterWorking Function) (60a, 60b) is a system that exists between the voice network and the Internet network (including the Internet) 90 to interlock.

VMS (Voice Messaging System) (50a, 50b) is a voice message transmission device for recording, storing and forwarding a voice message when the incoming call fails in the mobile communication system.

A voice message transmission system using VMS in the conventional mobile communication system is as follows.                         

When the call originator attempts to call by entering the called number (phone number of the B terminal) with the A terminal 10a, the switching centers 40a and 40b attempt to call the destination terminal 10b.

At this time, if the incoming call fails due to the location detection of the called terminal 10b or the terminal power off, the switching center 40a or 40b sends a voice message to the VMS 50b of which the caller is an additional device. Allows you to record and send to the called terminal.

The exchange stations 40a and 40b inform the destination terminal of the message that the voice message is stored in the VMS when the location of the destination terminal 10b is detected or the terminal power is turned on.

The receiving terminal 10b receiving the voice message arrival confirmation message receives the stored message by connecting to the corresponding VMS device 50b.

However, the conventional voice message delivery system using the VMS equipment has to be installed an additional additional equipment when the expansion, there is an inconvenience that must be operated separately from the communication service company.

In addition, the user has a disadvantage in that a separate fee must be paid for transmitting and confirming the voice message.

In addition, the amount of messages that can be stored and the length of messages are also limited by the capacity of the VMS.

Accordingly, the present invention has been made to solve the above problems, and relates to a transmission system capable of delivering a voice message through an email server when an incoming call fails. To provide a voice message management system and method of a mobile communication system. There is this.

The present invention includes: a transmitting terminal for checking a voice call between terminals and transmitting a voice file containing a caller's voice message together with the called party information; A wireless network for delivering a voice file received from the transmitting terminal to a network interworking device according to called party information; A swap server for searching an email address corresponding to the called party information inputted to the network interworking device and delivering the voice file to the corresponding address; And an e-mail server for storing the voice file input from the swap server in an e-mail server set by the called party's user on the Internet.

In addition, the swap server in the present invention is characterized in that the phone number and email information for the subscribers are matched one-to-one and sequentially stored in the email table.

In addition, the present invention comprises a first step of determining whether or not the originating terminal generates a call to the called terminal; A second step of transmitting a voice file recording the voice message and the called party information from the originating terminal to the swap server when the call reception fails as a result of the first step determination; A third step of retrieving the called party information transmitted in the second step from an email table of a swap server to transmit and store a voice file to the corresponding email server; And retransmitting the voice file stored in the e-mail server to the called terminal.

In the present invention, the voice file transmitted to the e-mail server is characterized in that it can be confirmed by a personal computer using the Internet.

Hereinafter, the present invention will be described with reference to the accompanying drawings.
