Abstract

In the case of providing a conventional premises broadcasting, there is a problem that an extension subscriber who cannot listen to the premises broadcasting is generated due to the surrounding environment as the same service is provided to all stations. Accordingly, the present invention implements a repeating premises broadcasting method by designating a station in a noisy or similar area as a specific group extension to record broadcast contents in the premises broadcasting and repeating the recorded contents to a specific group extension for a predetermined number of times. By doing so, it is possible to obtain the effect of accurately delivering information to extension subscribers in regions that are difficult to listen to on-premises broadcasting.

Description

Repeated Broadcasting Method of Private Exchange System

The present invention relates to a premises broadcasting method of a private switching system, and more particularly, to a repeating premises broadcasting method of repeatedly playing premises broadcasting to a set specific extension subscriber.

In general, a private exchange means a small exchange that switches communication terminals according to a plurality of extension subscribers in the same building, the same company, for example, a key phone system, a private branch exchange (PBX), a private automatic Private Branch Automatic Exchange (PABX). Such private exchanges provide various services to extension subscribers, and one of such functions is an on-premises broadcasting function.

The premises broadcasting function is a function of setting an premises broadcasting function by pressing an premises broadcasting function key using an extension terminal and broadcasting through an external speaker or a speaker of an extension terminal. The premises broadcasting function may be classified into a zone broadcasting function, an internal broadcasting function, and the like.

However, in the case of broadcasting the premises using the above-mentioned premises broadcasting function, only limited broadcasting is performed once or twice as the user directly uses a specific extension terminal. As a result, broadcasting contents can be delivered accurately in a quiet office, but in a noisy place such as a workplace, a problem of not delivering accurate broadcasting contents is caused.

Accordingly, an object of the present invention is to provide a premises broadcasting method that solves the above problems.

Another object of the present invention is to provide a premises broadcasting method for rebroadcasting premises broadcasting to a station subscriber of a specific region a predetermined number of times.

The present invention for achieving the above object is a recording process for recording the premises broadcast content when the premises broadcast requests to the premises broadcast request, and playback of the recorded premises broadcast contents when the execution of the premises broadcast is terminated by a specific extension A repeatable premises broadcasting method is implemented, which is a rebroadcasting process for broadcasting in groups.

More preferably, the repeating premises broadcasting method may be implemented to repeat the re-broadcasting process as many times as set by the operator.

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

FIG. 1 is a diagram illustrating an example of a private exchange system providing an on-premises broadcasting function, and schematically illustrates only essential components in implementing the present invention. Referring to the configuration shown in FIG. 1, it can be seen that the plurality of extension subscribers 120 (120_a to 120_d) and the main device 110 of the private exchange system. Although not shown in the drawing, the main device 110 includes a control unit including a central processing unit (CPU), a ROM, and a RAM, and a switching unit (T switch) 112, series, and parallel shown in the drawing. It can be seen that the conversion unit 114, the bottle and the serial conversion unit 118, and the storage device.

The control unit converts the serial broadcast to the parallel data by parallel programming and stores the data in the storage device 116 and then converts the parallel data of the storage device 116 into serial data by software programming. Through 112, it controls a series of operations to broadcast as many additional premises broadcasts as necessary to extension subscribers of a specific group. In this case, although the serial data converted from the parallel data is not shown in the figure, the serial data is converted into an analog signal through a codec. On the other hand, the operation of converting the serial data into parallel data is performed by the serial and parallel converter 114, and the operation of converting the parallel data into serial data is performed by the parallel and serial converter 118.

Operation of the control unit according to the present invention as described above is performed by the control flow shown in FIG. The control process shown in FIG. 2 includes a process of recording a broadcast in a premises and a process of repeatedly playing a content recorded with a specific extension set a predetermined number of times.

Hereinafter, an operation according to an embodiment of the present invention will be described in detail with reference to the above configuration. First of all, the following detailed operation is performed by the operator through the station # 1 120_a shown in FIG. 1, and the content of the station is transmitted through other general group extensions # 2 to m-1 and the specific group extensions #m and #n. Note that it is explained in advance on the assumption that it is broadcast.

The operator presses the premises broadcast button provided in extension # 1 120_a for premises broadcasting, which is provided to the controller of the main device 110. In step 210 of FIG. 2, the control unit determines this as a premises broadcasting request, and proceeds to step 212. If the control unit does not request premises broadcasting, the controller proceeds to step 224 to perform a corresponding function. In step 212, the controller controls the switching unit 112 to form a path so that the premises broadcasting content applied from the extension # 1 120_a can be provided to each of the extensions # 2 to n. By the path formation, the premises broadcast is made through all stations. In this case, it is preferable that the extension # 1 to #n use an extension terminal having a speakerphone mode, but when the extension terminal does not have the speakerphone mode, a separate premises broadcasting speaker should be used. While the premises broadcast is being made in step 212, the controller records the content being broadcast in the premises in step 214, and continuously checks whether the premises broadcast is terminated in step 216. The recording is performed through a path shown by a dotted line in FIG. 1, wherein the serial data form applied through the switching unit 112 is converted into a parallel data form via a serial and parallel converter 114. It can be seen that the device 116 is recorded.

In step 216, if the end of the premises broadcasting is detected, the controller proceeds to step 218 to play the recorded contents in the storage device 116 and transmit the set group extension 120_d. In this case, the specific group extension may be designated through a normal man machine communication (MMC) function. For example, the subscribers of a noisy area may be designated as the specific group extension. The recording and reproducing operation is performed in the reverse order of the recording operation. That is, the reproduction is performed through a path shown by a dashed line in FIG. 1, and in the path, parallel data read out from the storage device 116 under the control of the controller is converted into a serial data form in a parallel and serial converter 118. It can be seen that it is converted to and provided to the specific group extension 120_d desired through the switching unit 112.

Meanwhile, the additional premises broadcast in step 218 is rebroadcasted as many times as set by the operator in step 220. The number of rebroadcasts can also be set using the MMC function in the same way as to designate the specific group. Accordingly, the particular group extension 120_d subscriber can additionally listen to the premises broadcasting content as a set number of times, and if the set number of times is re-broadcasted, proceed to step 222 to switch to the standby state and to terminate the operation according to the present invention. do.

As described above, the present invention can obtain the effect of accurately delivering information by additionally re-broadcasting the premises broadcast to the subscribers of the station difficult to listen to the premises broadcast due to noise.
