Voice Message Management System and Method of Mobile Communication System

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 by 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, a voice message is received. It is a system for storing and transmitting.

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.

The base station (BTS) base station transmission subsystem (BTS) 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 a call originator attempts to call by inputting a called number (phone number of B terminal) with the A terminal 10a, the call attempts to reach the called terminal 10b through the switching centers 40a and 40b.

In this case, when the incoming call fails due to the location of the incoming terminal 10b or when the terminal power is turned off, the call allows the voice message to be recorded and sent to the VMS 50b.

When the location of the called terminal 10b is detected or the terminal power is turned on, a message indicating that a voice message is stored in the VMS is notified to the called terminal.

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 e-mail server when an incoming call fails, and to provide a voice message management system and method of a mobile communication system. There is this.

As shown in FIG. 3, a case in which a call is generated from a calling A terminal to a called B terminal is as follows.

First, when terminal A 100a attempts to make a call to terminal B 100b, the call attempts to make a call to destination terminal 100b via switching centers 40a and 40b (step 301).

It is determined whether the terminal B is called (step 302), and when the call fails because of the location detection of the terminal B (100b) or when the power is turned off, the call of the terminal A (100a) is not received. And the voice message recording menu (step 303).

If terminal B is available in step 302, a call is started between both terminals.

If the caller records a voice message to be delivered to terminal A 100a, it is converted into a voice file and stored (step 305).

The phone number of the calling party A terminal 100a, the telephone number of the calling party B terminal 100b, and the recorded voice file are transmitted to the swap server using the Internet network (step 306).

From the transferred data, the phone number of the terminal B, which is the called number, is found in the email table, and the terminal A transmits the telephone number and the voice file to the corresponding email server 900.

When the location of the terminal B, which failed to receive the call, is detected or the power is turned on while the email server 900 stores the information, a voice is transmitted from the corresponding email server 900 to the terminal B (100b). Announce the presence of a message (steps 308, 309).

The terminal B confirms the arrival of the voice message from the e-mail server 900 and presses the e-mail server access button on the keypad to receive the voice file to check the voice message.
