Abstract

The present invention relates to a frequency common communication system capable of operating voice mail. More specifically, in a frequency common communication system, when a called terminal does not answer for a predetermined time, a voice message is automatically left by using a voice mail function. The present invention relates to a frequency common communication system capable of operating a voice mail that enables a voice mail to be used on a called terminal side. In a frequency shared communication system, a voice mail service which is an additional information processing system 10 in a frequency shared communication system. By adding the function 11, the voice mail function can be operated in the common frequency communication system, so that if the called terminal does not answer the phone for a certain time, the voice mail service is automatically received to enable efficient use of the wireless channel. Frequency common communication By enabling the voice mail function in the system, it provides various functions to the user, and the system operator can effectively manage the system.

The present invention relates to a frequency common communication system capable of operating voice mail, and more particularly, to automatically leave a voice message using a voice mail function when a called terminal does not answer for a predetermined time in a frequency shared communication system. The present invention relates to a frequency common communication system capable of operating voice mail, which enables voice mail to be used on a called terminal.

In general, the frequency common communication system is composed of a terminal, a repeater, a network switch, and is connected to a group call, an individual call, a Japanese call, as well as a general PSTN (public network), so that domestic and international phone calls can be configured.

In the conventional common frequency communication system, as shown in FIG. 1, the terminal-1 (1) may call the general wired subscriber 9 and the terminal-2 (5), and conversely, the general wired subscriber 9 ) May also make a call to terminal-1 (1) or terminal-2 (5).

In order for the terminal-1 (1) to call the terminal-2 (5) through the public network, the user selects the telephone call mode and presses the 'call' button, and then the network switch through the DSU 6 through the repeater (2). 3) After receiving a call request signal and receiving a response message, you will hear a dial tone.

The terminal-1 (1) presses the telephone number of the terminal-2 (5) and the network switch (3) makes a telephone call with the terminal-2 (5) in reverse order through the public network (4) via the digital / analog trunk (8). By connecting, a call path is formed via the voice line 7.

In the conventional frequency common communication system as described above, when the terminal-1 (1) makes a call to the terminal-2 (5), the radio of the repeater 2 is continuously transmitted unless the terminal-2 (5) receives the call. Occupying the channel, the efficiency which is an original function of the frequency common communication system is reduced.

In addition, the terminal-1 (1) has a problem in that the terminal-2 (5) cannot transmit information unless the terminal-2 (5) receives a call.

The present invention improves the conventional problem as described above, when the called terminal does not answer for a certain time in a frequency common communication system, it automatically leaves a voice message using the voice mail function to use the voice mail on the called terminal side. The purpose of the present invention is to provide a frequency common communication system capable of operating voice mail.

In order to achieve the above object, the present invention is characterized in that the voice mail function can be operated in a frequency common communication system by adding a voice mail service function as an additional information processing system to the frequency common communication system. Provides a frequency common communication system capable of operating voice mail.

Hereinafter, a frequency common communication system capable of operating a voice mail according to the present invention will be described in detail.

First, as shown in FIG. 1, a configuration of a frequency common communication system capable of operating a voice mail according to the present invention is a network switch (VIPS) having a VALUE ADDED INFORMATION PROCESSING SYSTEM (10) to an existing frequency common communication system. 3), the voice mail service can be received using the VMS (VOICE MAIL SERVICE) 11 in the VIPS 10.

The present invention configured as described above operates as follows.

When the terminal-1 (1) calls the terminal-2 (5) and the network switch 3 does not answer the phone even after the elapsed time, the network switch 3 automatically uses the terminal using the VMS 11 in the VIPS 10. -1 (1) get voice mail service.

The terminal-1 (1) records the content to be transmitted to the terminal-2 (5) based on the message broadcast from the VMS (11). The network switch 3 receives the voice mail reception information periodically broadcasted through the DSU 6 via the repeater 2, and the LCD of the terminal-2 5 indicates that the voice mail has been received. On the confirmed terminal-2 (5) side, the information recorded in the VMS 11 can be confirmed through the voice mail telephone number.

When the terminal-2 (5) transmits a voice mail telephone number to the DSU 6 and the network switch 3 via the relay 2, the network switch 3 is recorded in the VMS 11 in the VIPS 10. The recorded contents of the terminal-1 (1) are transmitted to the terminal-2 (5) via the voice line (7) and the repeater (2).

The present invention constructed and operated as described above enables the user to receive a voice mail service automatically when the called terminal does not answer the phone for a certain time, thereby efficiently using the wireless channel, and to use the voice mail function in a frequency common communication system. This provides the user with multiple functions, and gives the system operator the ability to efficiently manage the system.
