The present invention relates to a device for performing PTT (Push To Talk) function in a key phone system. In particular, a PTT function of only a wireless terminal supported by a mobile phone or a radio includes a wired terminal as well as a wireless terminal. The present invention relates to an apparatus for performing a PTT function of a wired / wireless terminal in a keyphone system that is suitable to extend a broadcasting function supported by a keyphone system by supporting the case even when a group is provided.

In general, a key phone system is an efficient simple exchange system designed to be used by several people at the same time by installing a limited trunk line in the key phone main unit and connecting a key phone and a regular phone. Such a key phone system may be connected to a trunk line and an extension to perform a voice guidance function, an interrupt function, a broadcast function, a reception rejection function, a remote maintenance function, and the like. And the digital key phone system allows the exchange function to be performed by digital method.

On the other hand, PTT (Push-To-Talk) function allows several people to be registered as a group while one person talks while pressing the PTT button between them. Like a radio, several people can listen to the content at the same time. It is a function that is used in radios and is being extended to mobile phones.

Thus, PTT is similar to a walkie-talkie in such a way that a mobile user can call one-to-one or one-to-many without the need for dialing or direct dialing. Therefore, when using PTT, group communication by frequency band is possible, and there is no need for dial tones, dialing, ringing, and waiting. In addition, PTT is a system for providing voice and text-based one-to-one and group instant communication services in wired and wireless Internet environments.

1 is a block diagram of a device for performing a PTT function in a conventional key phone system, and FIG. 2 is a detailed block diagram of FIG.

First, the PTT wireless terminal 30 performs the same function as a general radio, and by pressing the PTT button input unit 31 to obtain a speaking right, it can be easily used in communication in which speed and promptness are emphasized.

In addition, the PTT wireless terminal 30 performs group communication for each frequency band, and can communicate only within a limited area, and uses a method of speaking only one person at a specific moment.

In addition, when the PTT uses a TRS (Trunked Radio System) scheme, there is no geographical limitation due to the relay function through the base station 20. However, there is a disadvantage in that the construction cost is high because it must be constructed in the form of a dedicated network of non-standard base stations. In addition, there is a disadvantage in that the price of the terminal is expensive, large, the design is clunky, and the choice of the terminal is small because a dedicated terminal must be used. In addition, since the number of base stations is small, communication is not possible in the subterranean and urban areas.

The PTT utilizes a wireless Internet Protocol (IP) infrastructure such as Code Division Multiple Access (CDMA) 1X, Evolution Data Only (EVDO), WLAN, and the like, and there is no cost for establishing a dedicated network. In addition, since it can be implemented in various types of IP terminals such as mobile phones, PDAs (Personal Digital Assistants, portable information terminals) and PCs (Personal Computers), there is no need to purchase dedicated terminals.

And the configuration for performing the conventional PTT function is the same as FIG.

Therefore, the PTT wireless terminal 30 is provided with a PTT button input unit 31 to support the PTT function.

In addition, the base station 20 receives the wireless signal transmitted from the PTT wireless terminal 30, converts it into a wired signal, and then transmits it to the key phone system 10.

In addition, the key phone system 10 receives a signal converted into a wired signal from the base station 20 to control several PTT wireless terminal 30, the key phone system 10 to store the data for each PTT wireless terminal group There is a built-in database 13.

Accordingly, when the PTT button is pressed by the PTT button input unit 31 to perform the PTT in the PTT wireless terminal 30, the central control unit 32 interprets the PTT button input unit 31.
