Dial Mode Setting Method of Subscriber Registration Device in Wireless Subscriber Network System

The present invention relates to a dialing for a general voice call when a RIU uses a telephone in a Radio Interface Unit (RIU) of a Wireless Local Loop (WLL) system. The present invention relates to a dial mode setting method of a RIU in a WLL system that can easily distinguish operations from dialing operations for fax data transmission.

In general, the WLL system is a system for configuring a link from a telephone station to a subscriber terminal by using a wireless system instead of a wired line. The WLL system is a subscriber compared to a public wired telephone network (hereinafter, referred to as a PSTN). It is expected to play an important role in the construction of information infrastructure in the future because of the low cost of installation and maintenance, the network can be constructed in a short time and easy to maintain.

As shown in FIG. 1, the WLL system includes a RIU 10, a base station 20 for forming a radio link with the RIU 10, and a RP 20. And a base station controller (hereinafter referred to as 'RPC') 30 and a WLL exchanger 40 to control 20.

As shown in FIG. 2, the RIU 10 converts an RF signal received from the RP 20 into an IF signal or an RF signal 11 converting an IF signal input from a subscriber into an RF signal. CDMA demodulating the IF signal converted by the RF unit 11 into a baseband signal or CDMA modulating the input baseband signal into an IF signal and outputting the resultant signal to the RF unit 11. By switching the baseband signal converted by the modem unit 12-1, 2 and the CDMA modem unit 12-1, 2 for each time slot and outputting the corresponding path or the baseband signal inputted for each time slot Time switches 13-1 and 2 outputted to the CDMA modem units 12-1 and 2 of the corresponding paths, and 16Kbps data switched and outputted by the time switches 13-1 and 2; Demodulate with 64Kbps Pulse Code Modulation (PCM) data or modulate 64Kbps PCM data into 16Kbps data To convert the vocoders 14-1 and 2 outputted to the time switches 13-1 and 2, and the 64 Kbps PCM data demodulated by the vocoders 14-1 and 2 into analog signals or input analog signals. Codec units 15-1 and 2 for converting 64Kbps PCM data to the vocoders 14-1 and 2 and the analog signals converted by the codec units 15-1 and 2 are impedance matched. The analog signal inputted through the line ports 17-1 and 2 to the subscriber's telephone or the analog signal inputted from the subscriber's telephone through the line ports 17-1 and 2, and then impedance-matched. And a control unit 18 for controlling the operation of each component block.

The line ports 17-1 and 2 of the RIU 10 configured as described above can be connected to general telephones for voice telephone calls, and faxes for data service are connected to perform facsimile data communication through the WLL system. can do.

However, in the prior art, the telephones connected to the line ports 17-1 and 2 of the RIU 10 cannot be distinguished from the RIU 10 whether the telephones are general telephones or facsimile data communications.

That is, in the RIU 10, there is a problem that the telephone dialing operation cannot distinguish whether it is a dialing operation for a general voice call or a dialing operation for facsimile data transmission.

The present invention has been made to solve the above problems, and its object is to designate a separate dialing number indicating a facsimile data transmission, and to input the designated dialing number first through a telephone, thereby dialing the RIU of the WLL system. The present invention provides a method for setting a dial mode of a RIU in a WLL system that can easily distinguish dialing operations for general voice calls and dialing operations for facsimile data transmission.

The dial mode setting method of the RIU in the WLL system of the present invention for achieving the above object, after setting a separate dialing number that tells the RIU to set or release the facsimile data transmission mode, DTMF (Dual) through the telephone If the dialing number input in Tone Multiple Frequency (Dual Phone) or DP (Dual Phone) form is the designated dialing number, the subsequent dialing operation detects that it is a dialing operation for facsimile transmission and sets the RIU to facsimile data transmission mode on or off. It is characterized by switching to perform data service by facsimile.

Hereinafter, with reference to the accompanying Figure 3 will be described in detail the dial mode setting method of the RIU in the WLL system according to the present invention.

First, a dialing number for the facsimile transmission mode is designated (S1) so that the control unit 18 in the RIU 10 stores it.

That is, a separate dialing number is designated to set the RIU 10 to facsimile data transmission mode or to release the facsimile data transmission mode.

Thereafter, when the user inputs a dialing number in the form of DTMF or DP through the telephone connected to the RIU 10, it is determined whether the dialing number is the dialing number for the facsimile transmission mode specified in the step S1 (S3). .

If the dialing number in step S3 is the facsimile transmission mode setting / release dialing number specified in step S1, then the dialing operation to be input in the control unit 18 in the RIU 10 is a dialing operation for facsimile transmission. Detect that

Then, the control unit 18 in the RIU 10 checks again whether the dialing number inputted again is a dialing number for setting the facsimile data transmission mode or a dialing number for releasing the facsimile data transmission mode (S4).

If the dialing number is a number for setting the facsimile data transmission mode as a result of checking in step S4, the RIU 10 is set to the facsimile data transmission mode to perform data service by the facsimile according to the dialing number input thereafter. If it is a number for releasing the facsimile data transmission mode, the RIU 10 is released from the facsimile data transmission mode so as to perform a voice call service by performing a dialing process for a general telephone call.

As described above, the present invention provides a facsimile data service using the RIU as the RIU of the WLL system can easily recognize whether the dialing operation of the telephone is for a general voice call or a facsimile data transmission. There is an effect that can be done more accurately.

Claims (1)
