Description

How to specify a Group Speed Dial for Key Phone System

The present invention relates to a speed dial method of a key phone system, and more particularly, to a method for designating a speed dial for each group.

In general, the key phone system has a separate speed dial used separately (by extension) and a common speed dial function commonly used at the system level. Here, the speed dial function stores frequently used telephone numbers or call numbers in memory corresponding to a certain one or two key data, and reads the number corresponding to the key data when the key data is input. It automatically dials without a manual dialing process. In other words, it is a function to perform dialing with less dial operation.

Therefore, since the common speed dial function of the small and medium capacity system uses one system in one office, it can be usefully used by storing the numbers that can be shared in one table.

However, in recent years, as the key phone system has been enlarged, many assignments of the co-dial dial table have increased the number of tables from two to three digits, causing inconvenience to users. That is, the biggest reason for using the speed dial is to dial with less movement. Pressing one digit more will result in half the effect of the speed dial. In addition, not all extension groups frequently use all the numbers registered in the common speed dial table. Therefore, assigning a number to a common speed dial will only cause unnecessary memory waste.

In addition, as the key-phone system has become larger in recent years, the use of a single system in multiple offices has become more common. In this case, a speed dial that can be used jointly in only one office is required, and the concept of the speed dial can be described as a group speed dial function, which is an intermediate space between an existing individual speed dial and a common speed dial.

Accordingly, the present invention provides a method for registering a speed dial for each extension group in a key phone system.

Another object of the present invention is to provide a method for performing a group reduction dial in a key phone system.

A method for designating a group speed dial of a key phone system for achieving the above objects includes: detecting a group speed dial registration code input, receiving a number and storing the number in a group speed dial table, and inputting the speed dial key to the group speed dial table; When the corresponding table number is input, checking whether the table number exists in the group shortened table to which the current extension belongs, and when the table number exists, reading a number corresponding to the table number and performing a dial. Characterized in that made.

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

1 is a diagram showing the configuration of a key phone system, the control unit 111 controls the overall operation of the key phone system to control call switching and provide various services to the user. The memory 112 includes a program for performing basic calls and various functions, a ROM for storing initial service data, and a RAM for temporarily storing data generated during program execution. The memory 112 is provided with a table relating to a speed dial according to the present invention. The switching circuit 113 switches various signals under the control of the control unit 111. The subscriber circuit 114 supplies a call current to the subscriber telephone under the control of the control unit 111 and simultaneously interfaces a signal between the subscriber telephone and the switching circuit 113. The ring generator 115 generates a ring signal and supplies it to the subscriber circuit. The trunk line circuit 116 forms a trunk line call loop under a control of the control unit 111 to form a trunk line CO, and interfaces a signal between the trunk line CO and the switching circuit 113. Here, the CO line CO refers to a line connecting the CO line circuit 116 and a national exchange (not shown). The tone generator 117 generates various tone signals under the control of the controller 111 and outputs them to the switching circuit 113. A dual tone multi frequency (DTMF) receiver 118 analyzes a DTMF signal input from the switching circuit 113, converts the DTMF signal into digital data, and outputs the digital data to the controller 111. Here, the DTMF signal input to the DTMF receiver in the switching circuit 113 is a telephone number generated by the trunk line subscriber or a telephone number generated by the extension subscriber. The DTMF transmitter 119 converts the digital data output from the controller 111 into a DTMF signal and outputs the DTMF signal to the switching circuit 113. Here, the DTMF signal output from the DTMF transmitter 119 becomes the telephone number of the trunk line subscriber generated when the trunk line is called from the station.

First, in order to implement the present invention, a table capable of registering a speed dial is required. That is, a table for registering individual shortcut dials, a table for registering common shortcut dials, and a table for registering group shortcut dials are required.

There may be two ways to allocate the tables.

The first is to allocate a certain amount of memory to register individual speed dials for each number of extension subscribers, to allocate a certain size of memory to register common speed dials, and to as many extension groups as to register speed dials per group. Another method is to allocate a certain amount of memory.

Secondly, there is a method of allocating a certain range of memory that can be used as a whole speed dial, and assigning and using as a single speed dial, a common speed dial, and a group speed dial as desired.

The first method has the disadvantage that the maximum number of each can be used, while the program can be simplified, and the second method has the advantage that the memory can be flexibly allocated and used as needed even though the program is somewhat complicated.

In addition, there should be a speed dial button (key) for performing the group speed dial function according to the present invention.

Memory allocation according to an embodiment to be described below uses the first method described above with reference to FIG.

FIG. 4 is a memory structure for storing shortcut dials according to the present invention. In FIG. The first area is the individual speed dial table area, table number 000 to 100. The second area is the extension group speed dial table area. The third domain is the system common speed dial table area, table numbers 201 to 300. In this case, the size of the memory may be large or small depending on the system, and when a predetermined size of memory is used as an extension, group, or joint speed dial area, the area is allocated as specified by the program.

In addition, the number of tables to be used for each extension in the individual speed dial table is also specified according to a program, and the number of tables is sequentially assigned as many as the number designated for each extension. For example, assuming that the number of tables is 20, table numbers 001 to 020 in FIG. 4 are used as individual short-dial dial areas of the first station.

In addition, a pointer buffer for individual speed dial table is stored to store starting address and number of tables for each station. Here, the start address is an address value for accessing the first table value of a table in which speed dial numbers corresponding to the corresponding station are stored.

Pointer buffers for the individual speed dials are shown in Table 1 below.

Extension number Start address Table count 001 **** 20 002 ???? 20 … … …

In addition, the group speed dial and the system speed dial table are stored in the same manner as the individual speed dial table, and the pointer buffer is also presented in the same way. The difference is that the group number is stored in the extension number area of the buffer in the case of the group short dial, and the tenant number is stored in the case of the co-short dial.

Here, the tenant is briefly described, and the tenant is intended to be used as a completely separate system while using one system, and different companies use separate systems in using multiple systems. It is the function that can have the same effect. That is, a company named A with tenant number 1 and a company called B with tenant number 2 use the same system but operate separately within the system.

2 is an operation flowchart for registering shortcut dials for each group according to an embodiment of the present invention.

First, the control unit 111 detects the system password input in step 211 and enters the programming mode. In step 213, the controller 111 receives a code for registering a group reduction dial.

In step 215, the control unit 111 which enters into the group short dial registration mode by the code input receives a group number. In step 217, the controller 111 checks the number of tables by referring to the group reduction dial pointer buffer.

In this case, if the number of tables is not confirmed, the controller 111 proceeds to step 217 and displays an error message on the display window of the key phone. In contrast, when the number of tables is confirmed, the controller 111 accesses the memory to the start address of the pointer buffer in step 219 and displays the table number corresponding to the start address on the display window. At this time, if there is data input corresponding to the table number, the data is displayed on the display window together with the table number.

Accordingly, the controller 111 corrects or deletes the data displayed on the display window by the user's key manipulation in step 221. In addition, another table number is searched for and a new telephone number is input. The controller 111 registers the input telephone number in the group reduction table.

3 is an operation flowchart for performing a speed dial function according to an embodiment of the present invention.

First, the control unit 111 detects the hookoff with the extension terminal in step 311 and detects the speed dial key input in step 313. In step 314, the control unit 111 receives a table number by a user's key input. In step 315, the controller 111 checks whether the input table number is a number existing in the speed dial table.

In this case, if the input table number is a number existing in the speed dial table, the controller 111 proceeds to step 317. If the number does not exist, the controller 111 proceeds to step 333 to determine whether a predetermined time for key input has elapsed. Check it. If the key input is not detected despite the elapse of the predetermined time, the controller 111 enters the error mode in step 343.

The control unit 111 proceeds to step 317 and checks whether the table number is a number of a group reduction dial table. In this case, if the table number is the number of the group reduction dial table, the control unit 111 proceeds to step 319. If the table number is not the number of the group reduction dial table, the control unit 111 proceeds to step 335 to check whether the number of the individual reduction dial table is the number. .

If it is determined that the number of the individual speed dial table is determined according to the result of the inspection, the control unit 111 proceeds to step 337 to switch the current mode to the individual speed dial mode and performs a speed dial function corresponding to the table number. On the other hand, if it is not determined that the number of the individual reduced speed dial table, the controller 111 proceeds to step 339 and checks whether the table number is the number of the common speed dial table.

If the table number is the number of the common speed dial table, the control unit 111 proceeds to step 341 to switch the current mode to the common speed dial mode and performs a speed dial function for the table number.

The controller 111 proceeds to step 319 and checks whether the table number is a table number of a group to which the hooked extension belongs. If the table number is the table number of the group, the controller 111 proceeds to step 321. If the table number is not the table number of the group, the controller 111 proceeds to step 329 and the speed dial of the group to which the table number belongs. Check that the number can be used on other stations. That is, it is checked whether the allowable flag is set so that the numbers of the table of the group (numbers inputted for speed dialing) can also be used in the extension of another group.

In this case, if the flag is set, the controller 111 proceeds to step 321. If the flag is not set, the controller 111 enters the error mode of step 342.

In step 319 or 329, the control unit 111 proceeds to step 321 to check whether the system is equipped with a TOLL CHECK function. Here, the toll check function is a function that performs a grade check for each station, and is a function for restricting a call to a specific number or a specific region. For example, it is a function that disables the long distance phone number stored in the group speed dial in a low grade station (extension that is restricted from long distance calls).

If the toll check function is provided, the controller 111 proceeds to step 323 to perform the toll check function on the hooked-up station. The control unit 111 checks whether the hooked-up extension in the step 325 can be dialed to the group speed dial number corresponding to the table number according to the toll check result. If the transmission is possible, the controller 111 proceeds to step 327. If the transmission is not possible, the controller 111 enters the error mode of step 343.

In step 321 or 325, the control unit 111 proceeds to step 327 to dial a group speed dial number corresponding to the table number and to perform a group speed dial function according to the present invention. Quit.

As described above, the present invention may be provided with a separate speed dial function that can be used jointly for each small group in an office, which is distinguished by business characteristics, by specifying a group speed dial in addition to the existing individual speed dials and common speed dials.

In other words, by assigning a number frequently used in a specific department, extensions belonging to the group can be used without a separate designation, and it can be used separately from other groups to prevent security or misuse.
