In step 102, the controller 102 checks whether the telephone currently being used is a key phone, and if it is not in a call, proceeds to step 106, where it is impossible to perform a broadcast group listening function. However, in step 102, in step 103, if the broadcasting group listening key signal is input in step 103, and if the broadcasting group listening key signal is input, the process proceeds to step 105 to perform the broadcasting group listening function. However, if the broadcast group listening key signal is not input, the broadcast group listening ID is checked. If the broadcast group listening ID is input, the process proceeds to step 105 to perform the broadcast group listening function.

As described above, the conventional broadcast group listening function was not possible to perform the function using a general telephone, and even in the case of a key phone, the broadcast function can be performed only through the speaker of the key phone which is making the call. Although the number of people can listen to the broadcast, it is impossible for a large number of people to listen if the distance between the telephone phone and the listener in the call is too far.

Accordingly, an object of the present invention is to provide a broadcast group listening method for performing a broadcast group listening function with a general telephone to solve the above problems.

Still another object of the present invention is to provide a broadcast group listening method for setting a broadcast zone inside or outside so that a large number of people can listen to a call through a speaker.

The present invention for achieving the above object, the process of detecting whether a multi-person mode selection key is input in the state of a call, and whether the telephone state in the call state when the multi-person mode selection key is input is a key phone or a general telephone Performing a search, inputting a broadcast group listening ID when the telephone is in a call, and performing an internal broadcast group listening function when an internal broadcast mode selection key is input after inputting the broadcast group listening ID. And if the external broadcast mode selection key is input after the broadcast group listening ID is input, performing the external broadcast group listening function.

The present invention for achieving the above object is a process of detecting whether a multi-person mode selection key is input in a call state, and a process of searching whether the telephone in the call state is a key phone telephone when the multi-person mode selection key is input; Checking whether a broadcast group listening key is input when the telephone is in use by a telephone, and performing an internal broadcast group listening function when an internal broadcasting mode selection key is input when the broadcasting group listening key is input; When the broadcast group listening key is input, the external broadcast mode listen key is input, and the external broadcast group listening function is performed.

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

The hardware block diagram according to the present invention is the same as in FIG. 1, the same reference numerals, but the speaker (not shown) is connected to the external broadcast connection circuit 90, the speaker is connected to a room with a general telephone Install.

Searching whether the telephone is a telephone, performing a broadcast group listening function by inputting a broadcast group listening ID when the telephone is in use, and a broadcasting group listening key when the telephone is in use. By performing a broadcast group listening function.

One preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 3 above.

The present invention performs a listening function by setting a broadcast group listening ID and storing the same in a memory 20, setting an internal or external broadcast zone, and designating a broadcast zone according to an internal or external broadcast mode selection key input.

First, in step 201, the controller 10 proceeds to step 202 if the telephone is busy. In step 202, the control unit 10 checks whether the multi-person mode selection key is pressed, and if the multi-person mode selection key is not pressed and the minority mode mode selection key is pressed, the control unit 10 performs a general broadcasting group listening function by a key phone telephone as in the conventional manner. And exit the program. However, when the multi-person mode selection key is pressed, the controller 10 checks whether the telephone being used is a keyphone telephone in step 203 and proceeds to step 204 if the keyphone telephone is not. In step 204, the control unit 10 checks whether the broadcast group listening ID is input from the general telephone through the extension subscriber circuit 70, and then proceeds to step 206 when the broadcast group listening ID is input. The broadcast group listening ID is an ID for selecting a broadcast function. However, if the telephone being used in the call in step 203 is a key phone telephone, the flow proceeds to step 205 to check whether the broadcast group listening key signal is input from the key phone telephone through the extension subscriber circuit 70 and if the broadcast group listening key signal is not input, the call continues. The state is maintained, and if the group broadcast listening key signal is input, the process proceeds to step 206. In step 206, the controller 10 checks whether the internal broadcast selection key is input to the internal broadcast mode through the internal subscriber circuit 70, and if the internal broadcast mode is set, in step 207, the controller 10 broadcasts the internal broadcast. Perform group listening. The internal broadcast performs the internal broadcast listening function through a speaker provided in a plurality of designated phone phones. However, if the external broadcast selection key is input through the internal subscriber circuit 70 in step 206 and is set to the external broadcast mode, the speaker connected to the external broadcast connection circuit 90 is controlled by controlling the external broadcast connection circuit 90. Use this function to listen to the external broadcasting group and end the program. The speaker connected to the external broadcast connection circuit 90 is installed on a wall or the like in the office, and when the broadcast content is transmitted to the speaker, everyone in the room can listen to the content.

As described above, according to the present invention, when a subscriber of a terminal receives a broadcast listening key signal or a broadcast group ID in a call state with a handset in a keyphone system, the device performs a group listening function according to an internal broadcast selection or an external broadcast selection. Personnel can listen to the contents of the call, and by selecting the external broadcast has the advantage of performing a broadcast group listening function using a general telephone.
