Hereinafter, with reference to the accompanying drawings will be described in detail the automatic connection device and connection method of the telephone in the RIU in the WLL system according to the present invention.

FIG. 2 is a block diagram of an automatic connection device of a telephone in a RIU in a WLL system according to the present invention. The RP is wirelessly matched with the RP 20 of the WLL system to receive an external subscriber's telephone through the switching center 40. Interface unit 11, the switching unit 12 for switching and connecting the external telephone input through the RP interface unit 11 to the telephone of the table, and the external connected by the switching unit 12 The internal line interface unit 13, which performs a matching function to connect the telephone with the internal telephone line of the telephone of the table, compares the call number stored in the memory with the call number input by the answering caller for the wireless call. According to the comparison result, the CPU 14 for controlling the switching operation of the switching unit 12 and the call number input during the wireless call and the unique number assigned to each telephone of the table are stored together. Or a memory 15 for storing announcement messages, a multimode selector for selecting whether to use the RIU in a multi-mode mode or simply as a collection of multiple telephone lines, and the multi-mode selector is on. In the multi-mode mode, the control port 16 includes a main port indicator indicating which port is main.

The operation of the automatic connection device of the telephone in the RIU in the WLL system configured as described above will be described with reference to the flowchart of FIG. 3.

First, after initializing each component block including the CPU 14 (S1), and then confirming a call signal from the telephone provided in the RIU through the RP 20 of the WLL system (S2), It is determined whether it is an incoming-call coming from inside or an outgoing call called from inside to outside (S3).

In the case of the external call in the step (S3) to check whether the corresponding identifier, such as a local call, long distance call, overseas call, wireless call is input (S4), if it is a wireless call using an identifier such as 012 or 015 (S5) A wireless call is performed by inputting the port number of the RIU assigned to its table phone together with the call number of the counterpart (S6).

Then, under the control of the CPU 14, the call number wirelessly called in the step S6 and the RIU port number assigned to the telephone used at this time are stored in the memory 15 (S7).

On the other hand, in the step (S5), in the case of an external call such as a local call, a long distance call, an overseas call, but not a wireless call, an external telephone call is made by inputting an external telephone number (S8).

Subsequently, in the case of the inter-telephone in the step S3, first, the guide message stored in the memory 15 is transmitted (S9).

That is, the caller will hear the message, "Here is (mutual name). Press 1 or 2 to answer the page."

Accordingly, if the caller presses 1 in response to the wireless call (S10), another time, "If you press your call number, we will connect you immediately." Send a guide message such as (S11).

According to the guidance message of the step (S11), when the caller who answers the wireless call enters his / her call number, the CPU 14 stores the call number stored in the memory 15 and the input call number. It is determined whether the comparison is the same (S12).

If the call numbers are the same in step S12, the switching unit 12 switches under the control of the CPU 14 to connect an external telephone with the telephone of the corresponding table of the unique number stored together with the call number ( S13) The person making the wireless call makes a phone call with the person who received the call from the outside (S14).

If step 2 is pressed in step S10, since it is not an answering call to the wireless call, it is connected to the telephone of the main table (S15) and the person at the main table receives the call (S16).

In addition, if the call numbers are different from each other in the offsetting step (S12), it may be a wrong call or a call of another business, and at this time, the telephone ring of the main table is similarly ringed (S15 and S16).

As described above, the present invention checks the answering phone for the wireless call and automatically rings the corresponding phone that matches the calling number and unique number to automatically connect with the calling person.

On the other hand, in the case of using a telephone having a liquid crystal display (LCD), the call number displayed is displayed by displaying the corresponding call number entered by the caller on the liquid crystal display of the telephones of all tables under the control of the CPU 14. Can make a phone call by picking up the phone

At this time, since the switching unit 12 cannot connect all the telephones of each table and transmit the call number data to be displayed at the same time, the call number data to be displayed by connecting each telephone sequentially using a polling method. Is sent to the telephone so that it is displayed on the liquid crystal display.

As described above, the present invention has the effect of being very convenient as well as reducing the waste of manpower by automatically connecting a person who manually changes the radio caller manually in the RIU of the WLL system.
