1 is a functional block diagram of a wired telephone off-hook warning sound transmitting device in a SLL system according to an embodiment of the present invention, the wired telephone off-hook warning sound transmitting device in a PLL system according to an embodiment of the present invention is RF ( WLL terminal 100 having a radio frequency (hereinafter referred to as RF) 101, a transmitter / receiver 101, a mobile station MODEM (hereinafter referred to as MSM) 102, and a wired telephone interface 103; ), A wired telephone 200 and the like.

The R / F transmitting / receiving unit 101 mounted in the WLL terminal 100 performs an RF transmitting / receiving operation with the base station 1.

In addition, the MSM 102 mounted in the WLL terminal 100 is a modem that has a built-in timer and performs overall control operations of the WLL terminal 100. The wired telephone detected by the wired telephone interface unit 103 is a modem. Receives the on / off hook state signal of the (200) receives the on / off hook state of the landline phone 200, and after the call is terminated the state of the call / handset of the wired telephone 200 off hook In the state it plays a role of transmitting a warning sound to the wired telephone interface unit 103.

In addition, the wired telephone interface unit 103 mounted in the WLL terminal 100 is a circuit that is responsible for the interface between the WLL terminal 100 and the external wired telephone 200, and is on / off hook of the wired telephone 200. After detecting the status, the status signal is transmitted to the MSM 102, and when the alarm signal is received from the MSM 102, the alarm sound signal is transmitted to the wired telephone 200.

On the other hand, the landline phone 200 is a phone that is connected to the WLL terminal 100 and allows the user to make a phone call.

Next, a description will be given of a method for transmitting a warning sound off-hook when a landline telephone off hook system according to an embodiment of the present invention using a wired telephone off-hook warning sound transmitting device in a SL system having the above configuration.

2 is an operation flowchart illustrating a method of transmitting a warning sound during off-hook in a wired telephone according to an embodiment of the present invention.

First, the wired telephone interface unit 103 detects a transmitter / receiver status of the wired telephone 200 and transmits the status signal to the MSM 102. Then, the MSM 102 receives the handset / handset state signal transmitted from the wireline telephone interface unit 103 and then determines whether the handset / telephone state of the wireline telephone 200 is off-hook or on-hook. It is determined whether or not (S1). Here, the state where the handset / handset of the landline phone 200 is in an off-hook state means that the handset is detached from the body of the phone, and that the state of the handset / handset of the landline phone 200 is in an on-hook state. It means that the handset is placed on the telephone body normally.

At this time, if the transmitter / receiver state of the landline 200 is off-hook in the first step S1, the MSM 102 determines whether the state of the base station 1 is in a call termination state. (S2).

If the state of the base station is the call termination state in the second step (S2) (YES), the MSM 102 drives the timer mounted therein to set the off-hook state of the landline 200, That is, it is determined whether it lasts for 30 seconds (S3).

At this time, when the off-hook state of the wireline telephone continues for 30 seconds (YES) in the third step (S3), the MSM 102 transmits a warning sound signal to the wireline telephone interface unit 103. Then, the wired telephone interface unit 103 receives the warning signal transmitted from the MSM 102 and transmits a warning sound to the user for a predetermined time, that is, 3 minutes through the handset of the wired telephone 200 (S4). ).

Then, the MSM 102 determines whether or not the alarm sound sending operation has been performed a set number of times, that is, twice (S5).

At this time, if the warning sound sending operation is not performed twice in the fifth step S5 (NO), the MSM 102 proceeds to the third step S3, and if both warning sound sending operations are performed ( YES) The MSM 102 transfers its silent mode to the landline 200 at the same time as switching its call mode to sleep mode (S6). Here, the above-described sleep mode means a state in which the WLL terminal 100 repeatedly performs an operation of turning on to determine the state of the base station 1 and then turning off after a predetermined time.

Then, the MSM 102 determines whether or not an incoming ring signal is received from the base station 1 (S7).

At this time, if the incoming ring signal is not received from the base station 1 in the seventh step (S7) (NO), the MSM 102 performs the user hooking through the handset / receiver of the landline 200 It is determined whether or not (S8). Here, the aforementioned hooking operation refers to an operation in which the user places the off / hook handset on the main body of the wired telephone 200 and then lifts it again to perform a call.

If the user does not perform the hooking operation through the handset / receiver of the wired telephone 200 in the eighth step S8 (NO), the MSM 102 proceeds to the seventh step S7 again. When the user performs the hooking operation through the handset / receiver of the wired telephone 200 (YES), the MSM 102 switches its call mode to the calling mode and performs normal call processing operation and then ends ( S9).

On the other hand, in the first step (S1), the state of the telephone receiver / handset of the wired telephone 200 is on-hook state, or in the third step (S3), the time when the off-hook state of the wired telephone 200 is set, that is, If it does not last 30 seconds (NO), the MSM 102 transitions to the sleep mode and proceeds to the seventh step (S7) (S10).

In addition, when the state of the base station 1 is not in the call termination state (NO) in the second step S2 (NO), the MSM 102 performs normal call processing operation and then returns to the first step S1. Proceed (S11).

When the incoming ring signal is received from the base station 1 in the seventh step S7 (YES), the MSM 102 uses the handset / handset status signal transmitted from the landline interface 103. Then, it is determined whether the state of the handset / handset of the wired telephone 200 is off-hook or on-hook (S12).

At this time, in the twelfth step (S12), if the transmitter / receiver state of the wired telephone 200 is in an on-hook state, the MSM 102 transmits an incoming ring signal to the wired telephone interface unit 103 at the same time. Switch your call mode to incoming mode. Then, the wired telephone interface unit 103 receives the incoming ring signal transmitted from the MSM 102 and sends it to the wired telephone 200 to perform a normal call processing operation (S13).

On the other hand, in the twelfth step S12, if the transmitter / receiver state of the wireline telephone 200 is in an off-hook state, the MSM 102 synthesizes an incoming ring signal and an alarm sound and then combines the synthesized signal with the wired signal. Transfer to the phone interface unit 103. Then, the wired telephone interface unit 103 receives the incoming ring signal transmitted from the MSM 102 and the combined signal and transmits the signal to the wired telephone 102 (S14).

Subsequently, the MSM 102 determines whether the user has performed the hooking operation through the handset of the wired telephone 200 (S15).

At this time, if the user does not perform the hooking operation through the handset / receiver of the wired telephone 200 in the fifteenth step S15 (NO), the MSM 102 proceeds to the fourteenth step S14 again. On the other hand, when the user performs the hooking operation through the handset / receiver of the wired telephone 200 (YES), the MSM 102 switches its call mode to the incoming mode and performs normal call processing operation (S16). ).

Therefore, according to the above-described operation of the present invention, the landline telephone 200 automatically generates a warning sound when the call / handset state of the landline telephone 200 is off-hook when a call is terminated. This causes the user to hear the beep and call the handset on hook.

As described above, according to the method for transmitting an off-hook warning sound in a landline telephone in a LLL system according to the present invention, when the telephone / handset of the landline telephone is off-hook even though the user's call is terminated, the system automatically enters the sleep mode. In addition, it has an outstanding effect of preventing the current from continually being consumed, thereby increasing the standby battery standby time.

Another effect is that it automatically alerts the user when the landline phone's handset is off-hook even when the user's call is ended, allowing the user to quickly overcome the error. It works.
