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

FIG. 1 is a schematic diagram of a subscriber interface device (RAU) according to an embodiment of the present invention, which includes a data processing unit 10, a control unit 20, and first to n-th user interface units 30 and 40. It consists of 50.

The data processing unit 10 includes a time switch, and has the input voice data in the corresponding slot, but in case of an extension according to the control signal, the data is put in the slot for extension, and the data to be transmitted to the outside is It puts data in the slots and transfers the input DTMF / DP signal to the controller.

The control unit 20 transmits a dial tone signal and a ring signal, and performs a switching function of these signals.

In addition, the user interface unit 30 converts analog voice data input from the outside into digital data to A / D (Analoge to Digital), and then transfers the data to the data processor at 2.048 Mbps or performs reverse conversion. The data processing unit interface unit 31, the DTMF / DP receiver 32 which converts the analog DTMF / DP signal received from the user's telephone to the data processing unit interface unit, and the user hooks off the handset. A hook-off detector 33 which detects whether or not the signal is transmitted to the control unit, and a ring signal that transmits a dial tone signal to the user according to a control signal to the control unit, and informs the user that there is a call from the outside. It consists of a ring / tone generator 34 to transmit.

The operation flow of the subscriber access device having such a configuration will be described.

When the hook-off detector 33 detects a hook off, it notifies the control unit 20, and the control unit 20 outputs a control signal to generate a tone signal generator in a tone generator. 34, the user presses a button on the phone, and the first DTMF / DP signal is stored in the memory via a time switch with the DTMF / DP receiver 32. When the CPU receives this DTMF / DP signal and outputs a control signal to stop transmission of the dial tone signal, the remaining DTMF / DP signals are stored in the memory of the control unit 20 in the same way as the path of the first DTMF / DP signal. The CPU of the control unit 20 reads this from the memory and compares whether it is an extension number.

In the case of the extension number, the CPU of the control unit 20 operates the user's ring generator (ring generator of the ring / tone generator, 34) to enter the voice data into a time slot corresponding to the extension. If the information is passed to the time switch, and if it is not an extension number, the CPU passes the information to the time switch to enter the hook-off signal and data information out of the time slot.

FIG. 2 is a flowchart illustrating a method for controlling an extension function of a subscriber access device of the present invention. The hookoff detector 33 performs a first step S1 of detecting a hookoff signal from a user's telephone, and then hooks off the hookoff signal. When the detection unit 33 detects the hook-off signal, the detection unit 33 transmits the dial tone to the control unit 20. The control unit 20 outputs a control signal for operating the tone generator and transmits a dial tone informing the user that a current call is available. Perform step 2 (S2).

Subsequently, the button is pressed while the dial tone is heard, and the first DTMF / DP signal is stored in the memory of the controller 20 through the time switch via the DTMF / DP receiver 32. Next, when the CPU receives the first DTMF / DP signal, a fourth step S4 of outputting a control signal of turning off the dial tone is performed.

Next, the controller proceeds to a fifth step S5 of receiving the remaining DTMF / DP signals from the time switch and storing them in a memory, and then reading a DTMF / DP signal stored in the memory in a sixth step S6. Perform

The controller proceeds to a seventh step S7 of comparing the telephone number read from the memory with the extension number registered in the subscriber access device, and then whether the telephone number read from the memory is the extension number registered in the subscriber access device. The eighth step (S8) to check whether or not is performed.

As a result of the determination of the eighth step S8, when the telephone number read from the memory is the extension number registered in the subscriber access device, a ninth step S9 of operating a ring of the subscriber number registered in the extension number is performed. After that, the tenth step S10 of loading data in the timeslot of the subscriber registered in the subscriber access device among the timeslots of the time switch is performed.

On the contrary, if it is not an extension number registered in the subscriber access device, it corresponds to an external number, i.e., a general telephone number, among time slots of the time switch. The eleventh step S11 of exporting is performed.

As described above, the present invention reduces the unnecessary traffic to the base station (RP), control station (RPC), local exchange (LE) of the wireless subscriber network by providing a subscriber station (RIU) extension function of the wireless subscriber network. Not only can stabilization of the network, but also has the advantage that can provide a more enhanced service to the subscriber.
