Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing each configuration means suitable for applying a voice message transmission method in a wireless paging system according to an embodiment of the present invention, the first control unit 110, NIU (network interface unit: 120) Server 100 and a second control unit 210, a modem 220, a second storage unit 230, and a server D on the wireless call provider side including the A / D conversion unit 130 and the first storage unit 140. And a PC 200 on the radio call subscriber side composed of the / A changer 240 and the speaker 250.

First, in order to perform the voice message transmission method of the wireless paging system according to the present invention, that is, in order for each subscriber to download the voice message transmitted to his / her own PC, the wireless paging service provider provides a wireless paging service. Each subscriber must provide a dial-up service or a PC communication service to allow access to the server system through its PC.

Referring to the drawings, the first controller 110 controls the overall operation of the server system 100, and in particular with respect to the voice message transmission method according to the present invention, from the outside through the NIU 120 to be described later When the voice message for the subscriber of the transmission is received, it is provided to the A / D conversion unit 130 to be described later. At this time, the above-described NIU (120) is a data receiver (not shown) for receiving a variety of message data (including voice message, text, numeric message data) provided through a general telephone network and the received voice message data to each subscriber side It is configured to include a modem (not shown) for transmitting to the PC 200 in the form of a digital data stream.

The A / D converter 130 receives the analog voice message received through the NIU 120 from the controller 110 to convert the analog voice message into a digital data stream and outputs the digital data stream. A digital data stream for each subscriber output from the unit 130, that is, a voice message for each subscriber converted into digital data is stored.

On the other hand, the modem 220 of the PC 100 provided on the subscriber side attempts to connect to the server 100 of the wireless calling provider side through the telephone network, and receives a voice message in the form of a data stream transmitted from the server 100. Done.
