Description

How to specify group speed dial for the keyphone system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed dialing method of a key telephone system, and more particularly, to a method of assigning a speed dial to each group.

In general, the key telephone system has individual speed dials used individually (in-line) and common speed dials used jointly at the system level. Here, the abbreviated dialing function refers to a function of storing a frequently used telephone number, a calling number, etc. in a memory corresponding to a certain (one or two) key data and reading a number corresponding to the key data when the key data is input So that dialing is performed automatically without manual dialing. That is, it is a function to perform dialing with a small dial operation.

Therefore, since the common speed dialing function of the small-capacity system uses one system in one office, it can be usefully used by storing commonly used numbers in one table.

However, as the key telephone system has become larger in recent years, many assignments of the common speed dial table cause the table number to increase from a two-digit number to a three-digit number, thereby inconveniencing the user. That is, the greatest reason to use the speed dial is to dial with fewer operations, and pressing one more digit will result in a reduction in the effect of the speed dial. In fact, not all extension groups frequently use all the numbers registered in the common speed dial table. Therefore, assigning many numbers to a common speed dial will only waste unnecessary memory.

Recently, as the key telephone system has become larger, more and more systems are commonly used in various offices. In this case, it is necessary to use a speed dial that can be used only in one office, and the speed dial concept can be explained by the group speed dial function which is halfway between the existing individual speed dial and the common speed dial.

Accordingly, the present invention provides a method of registering a speed dial on an extension group basis in a key telephone system.

It is another object of the present invention to provide a method of performing a group speed dial in a key telephone system.

A method of assigning a group speed dial to a key telephone system, the method comprising the steps of: detecting a group speed dial registration code input and storing the number in a group speed dial table; Checking whether the table number exists in the group short table to which the currently used extension belongs when the corresponding table number is input; and reading out the number corresponding to the table number when the table number exists, .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

FIG. 1 illustrates a configuration of a key phone system. The controller 111 controls the overall operation of the key phone system to control call switching and provide various services to a user. The memory 112 includes a basic call and a program for performing various functions, a ROM for storing initial service data, and a RAM for temporarily storing data generated during program execution. Here, the memory 112 includes 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 provides a call current to the subscriber's telephone under the control of the controller 111 and at the same time interfaces signals between the subscriber's telephone and the switching circuit 113. The ring generator 115 generates a ring signal and supplies it to the subscriber circuit. The CO line circuit 116 seizures the CO line under the control of the controller 111 to form a CO line loop and interfaces the CO line to the switching circuit 113. Here, CO line CO refers to a line connecting the CO line circuit 116 and a public switch (not shown). The tone generator 117 generates various tone signals under the control of the controller 111 and outputs the generated tone signals to the switching circuit 113. The dual tone multi frequency (DTMF) receiver 118 analyzes the 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 an 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 is the telephone number of the trunk line subscriber generated when the trunk line side is called from the extension side.

First, for implementation of the present invention, a table capable of registering a speed dial is required. That is, a table capable of registering an individual speed dial, a table capable of registering a common speed dial, and a table capable of registering a group speed dial are required.

There are two ways to allocate the tables.

A first memory allocates a memory of a predetermined size for registering individual speed dials by the number of each extension station, allocates a memory of a predetermined size for registering a common speed dial, Another method is to allocate a certain amount of memory.

The second is to allocate a range of memory that can be used for the entire speed dial, and allocate it as needed for individual speed dial, shared speed dial, and group speed dial as desired.

The first method has the disadvantage that the maximum number that can be used is fixed, while the program can be simplified, and the second method is advantageous in that the memory can be allocated and used flexibly as needed even if the program is somewhat complicated.

Further, there is a speed dial button (key) for performing the group speed dial function according to the present invention, which follows the existing one.

The memory allocation according to an embodiment to be described below uses the first method and will be described with reference to FIG.

FIG. 4 is a memory structure for storing the speed dials according to the present invention. The first area is an individual speed dial table area, with table numbers 000-100. The second area is an extension group speed dial table area, and the table numbers 101 to 200 are used. The third area is the area of the system common speed dial table, from table numbers 201 to 300. Here, the size of the memory may be increased or decreased according to the system, and when a memory having a predetermined size is used as an extension, group, or shared speed dial area, the area is allocated as designated 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 the program, and the number of tables is sequentially allocated by the number specified by the extension. For example, assuming that the number of the tables is 20, the table numbers 001 to 020 in FIG. 4 are used as the individual speed dial areas of the first extension.

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

The pointer buffer for the individual speed dial is shown in Table 1 below.

[Table 1]

Extension number Start address Number of tables One **** 20 2 ???? 20 ... ... ...

Also, the group speed dial and the system common speed dial table are stored in the same manner as the individual speed dial table, and the pointer buffer is presented in the same manner. If there is a difference, the group number is stored in the extension number area of the buffer in case of the group speed dial, and the TENANT number is stored in the case of the common speed dial.

Hereinafter, the Tennant will be used as a totally separate system using one system. In the case where several companies use the same system, each company uses a separate system It is a function that can have the same effect. In other words, company A with Tennant number 1 and company B with Tennant number 2 use the same system but operate separately within the system.

2 is a flowchart illustrating an operation for registering a speed dial for each group according to an exemplary embodiment of the present invention.

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

The controller 111, which has entered the group speed dial registration mode by the code input, receives the group number in step 215. In step 217, the controller 111 refers to the group speed dial pointer buffer to check the number of tables.

If the number of the tables is not confirmed, the controller 111 proceeds to step 217 and displays an error message on the display window of the phone. On the other hand, if the number of the tables is confirmed, the controller 111 accesses the memory at 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 corresponding to the table number, the data is displayed on the display window together with the table number.

Accordingly, the controller 111 modifies or deletes the data displayed on the display window in step 221 by a user's key operation. In addition, another table number is searched to input a new telephone number or the like, and the control unit 111 registers the inputted telephone number or the like in the group short-cut table.

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

First, the controller 111 detects a hook-off from the extension terminal 311 to the extension terminal and detects a speed dial key input in step 313. In step 314, the control unit 111 receives the table number by inputting the user's key. In step 315, the control unit 111 determines whether the inputted table number exists in the speed dial table.

If the inputted table number is a number present in the speed dial table, the controller 111 proceeds to step 317. If the entered table number is not present, the controller 111 proceeds to step 333 and determines whether a predetermined time has elapsed Inspect. If the key input is not detected despite the lapse of the predetermined time, the controller 111 enters the error mode in step 343.

The controller 111 proceeds to step 317 and checks whether the table number is a group speed dial table number. At this time, if the table number is the number of the group speed dial table, the controller 111 proceeds to step 319. If the number is not the number of the group speed dial table, the controller 111 proceeds to step 335 to check whether the speed dial number is an individual speed dial number .

If the number of the individual speed dial table is determined according to the result of the check, the controller 111 proceeds to step 337 and switches the current mode to the individual speed dial mode to perform the speed dial function corresponding to the table number. On the other hand, if it is not the number of the individual 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.

At this time, if the table number is the number of the joint speed dial table, the controller 111 proceeds to step 341 and switches the current mode to the common speed dial mode and performs the speed dial function for the table number.

On the other hand, the controller 111 proceeds to step 319 and checks whether the table number is a table number of a group to which the hooked-off 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, Check whether the number is available on the other extensions. That is, it is checked whether or not the permission flags are set so that the numbers of the tables of the group (the numbers inputted for the speed dial) can be used in the extensions of other groups.

At this time, if the flag is set, the controller 111 proceeds to step 321, and if the flag is not set, the controller 111 enters the error mode of step 342. [

In step 319 or 329, the controller 111 proceeds to step 321 to check whether the present system has a TOLL CHECK function. Here, the toll check function is a function to perform a rating check for each extension, and restricts a call to a specific number or a specific area. For example, it is a feature that makes it impossible to use a local phone number stored in a group speed dial in a low-grade extension (a station that is restricted from being allowed to make long-distance calls).

If the toll check function is provided, the controller 111 proceeds to step 323 to perform a toll check function on the hook-off extension. In step 325, the control unit 111 checks whether the hooked-off extension can originate a call to the group speed dial number corresponding to the table number. At this time, if the calling is possible, the controller 111 proceeds to step 327. If the calling is not possible, the controller 111 enters the error mode in step 343. [

The control unit 111 proceeds to step 327 according to the determination of step 321 or step 325. The control unit 111 performs a dial operation using the group speed dial number corresponding to the table number and performs a group speed dial function according to the present invention And terminates.

As described above, according to the present invention, it is possible to designate a group speed dial in addition to an existing individual speed dial and a common speed dial, so that it is possible to provide a separate speed dial function that can be jointly used in small groups in an office classified by business characteristics.

In other words, by assigning frequently used numbers to specific departments, the stations to which the group belongs can be used without any designation, and it is possible to prevent security or misuse because it is used separately from other groups.
