The present invention relates to a transmission method and an apparatus thereof.

In general, a key phone system consists of a plurality of station subscriber terminals assigned to each unique number, and a main device that handles the overall operation of connecting the trunk line, the station, and the internal department of the station by connecting a predetermined number of trunk lines with the local exchange. In the conventional key-phone system, the operation of any extension terminal subscriber to transmit the same message to several extension terminal subscribers is as shown in FIG. 2 of the accompanying drawings. If a subscriber with extension 120 wants to deliver a message for conference call and meeting time to several extension terminals, e.g. subscribers with extension numbers 100 to 109 (step 101), the subscriber with extension 120 uses his terminal. Call the subscriber of the extension terminal having the extension number 100 (step 102) And it determines whether a response signal for the call is detected from the end (step 103). If the response of the call is not detected from the 100 extension terminals called by the 120 extension terminal subscribers to which the message is to be transmitted in step 103, the 120 extension terminal subscribers to which the message is to be forwarded is sent to the 100 extension terminals. The call of the extension is reserved or call 101 of the 100 extension terminal (step 106) is judged whether or not a response signal to the call is detected from the called 101 extension terminal (step 107).

When the off-hog signal connecting the call path is detected from the 100 extension terminals called in the determination of step 103, the 120 extension terminal subscribers transmit the message for the meeting call and the meeting time to the 100 extension terminal subscribers and then receive the handset means. Block the call by hooking on (step 105).

Thereafter, the 120 extension terminal subscriber calls 101, the next extension terminal subscriber's number (step 106), and then determines whether or not a response signal for the call is detected from the called 101 extension terminal (step 107). ).

If it is determined in step 107 that a response signal for a call is not detected from the extension 101 terminal, the 120 extension terminal subscribers perform the same operation as in step 104 (step 108), and then call and conference the next extension terminal subscriber. In order to transmit the time, call 102 of the extension terminal (step 110) to determine whether or not a response signal for the call is detected from the 102 extension terminals (step 111), and the 101 extension terminal is called. When the response signal to the call is detected from the 120 extension terminal subscribers perform the same operation as in step 105, and then call 102 of the next extension terminal (step 110) to answer the call from the 102 extension terminal called. It is determined whether is detected (step 111).

As described above, in the conventional key phone system, when any extension terminal subscriber wants to transmit a message to a plurality of extension terminal subscribers, an individual extension terminal must be designated and called, which causes troublesome message transmission. If the subscriber is absent there was a problem that can not transmit the desired message.

The present invention has been made in view of the above-described problems, and an object thereof is to transmit a broadcast after setting a group of extension terminals that any subscriber terminal wants to transmit when any subscriber station has a message to be transmitted to a plurality of extension terminal subscribers.
