Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to a terminal telephone (so-called, In a stored program control type telephone device such as an electronic exchange or an electronic button telephone device, which has a processor and memory in both the terminal telephone (key telephone), the line selection button is used to select a line when making various outgoing calls or answering incoming calls from the above-mentioned terminal telephone. This is related to the method.

(Prior art and its problems) In a storage program control type telephone device that accommodates a terminal telephone (so-called button telephone) having a large number of operation buttons including a plurality of non-lock type line selection buttons, Conventionally, as a line connection method from a telephone, an off-hook operation (the operation of lifting the handset and closing a switch, or the operation of a specific button that has the same effect as closing a switch) is performed within a certain period of time after pressing the line selection button. ), or by pressing the line selection button after an off-hook operation, each time you connect the line, press the line selection button. I needed a push.

However, in recent years, the use of so-called key telephones in offices and the like has expanded, and there is a growing desire for improved operability, especially with regard to the use of telephone lines. For this reason, for example, when answering an incoming call from a central office line, a response line can be specified for each terminal telephone to quickly respond to incoming calls from outside, while when making a call from the central office line, the line selection In order to avoid competition with other terminal telephones, it is conceivable to provide services such as distributing and allocating lines for use to each terminal telephone by submitting a service order to the main device, etc. In this type of line selection method, the user cannot freely set the line to be used for each terminal phone out of multiple accommodated lines, and this deteriorates the operability of so-called button phones that have a large number of buttons. There are drawbacks to doing so.

In addition, a telephone device in which a priority line is set on each telephone and the priority line is automatically selected by an off-hook operation without having to perform a line selection operation when making a call is disclosed, for example, in Japanese Patent Application No. 52-69075. (Japanese Unexamined Patent Publication No. 54-4002), however, in this telephone device, the setting of the priority line is done by connecting specific terminals on the telephone, so the setting of the priority line is semi-fixed. Registration and deregistration of priority lines must be done by installing or removing connections between the above specified terminals.

(Objective of the present invention) In order to eliminate these drawbacks, the present invention provides a method that does not require specific operations such as inputting a service order to the main device, etc., or without installing or removing connections between specific terminals. , line selection button, etc. The line to be used preferentially can be designated and canceled for each terminal telephone by the normal operations of the terminal telephone user, such as pressing other function buttons, off-hook operations, and on-hook operations. The purpose is to improve the operability of so-called button telephones.

(Summary of the Invention) For the above purpose, the present invention addresses the difference in the order of operations between the off-hook operation of a terminal telephone and the pressing operation of the line selection button of the terminal telephone, that is, which operation is performed first. The selected line is maintained as selected even after the on-hook operation of the terminal telephone is performed.

That is, for example, when an off-hook operation is detected on a terminal telephone, it is determined whether or not there is a line selection button in the operating state that has already been pressed on the terminal telephone, and if there is a line selection button in the operating state. In this case, the line selection button that is in the operating state is set to continuous operation mode (or operation cancellation mode), and if there is no line selection button that is in the operation state, the line selection button that is selected and pressed after the off-hook operation is set to operation cancellation mode. (or continuous operation mode). In addition, operation continuation mode means that the line selection button in operation maintains its operating state even after on-hook operation on the terminal phone, and operation cancellation mode means that the line selection button in operation remains in operation even after on-hook operation on the terminal phone. shall be restored.

In addition, if a terminal telephone has a line selection button in continuous operation mode, if the terminal telephone is placed on-hook and any line selection button or other function button is pressed, the continuous operation mode of the line selection button will be canceled. Ru.

As described above, the present invention detects the order of the user's normal operations such as pressing the line selection button and other function buttons, off-hook operation, and on-hook operation, and determines whether or not to continue setting the line selection. Automatically identifies and performs off-hook operation only (if there is a line selection button in continuous operation mode) or off-hook operation and pressing the line selection button (if there is no line selection button in continuous operation mode)
Accordingly, the desired line connection can be established, and the line selection can be maintained and canceled only by operating the buttons.

shows. Note that FIG. 3 shows a case where the operation continuation mode is set when there is a line selection button that has already been pressed during the hook-off operation.

Below, with reference to FIGS. 1 and 2, and in accordance with the operation flowchart of FIG. 3, the line connection operation from the terminal telephone according to the embodiment of the present invention will be described.

(1) When the line selection button is pressed before an off-hook operation (Setting the line selection button's operation continuation mode and line selection operation in the operation continuation mode: see Figure 3 A and C) In Figure 1, When, for example, a line selection button LK8 (not shown) is pressed on the terminal telephone KT, the pressed line selection button LK8 is detected in the terminal telephone KT in a known manner, and the route and extension interface unit are detected.
Information on the pressed line selection button LK8 (hereinafter referred to as LK8 information) is sent to the central processing unit CC via the STU and the route and is received by a known method. The central processing unit CC reads the bit numbers 0 to 0 of the address field corresponding to the terminal telephone KT of the button status register KYSTR of the main memory MM (the position where the number on the right side of Fig. 2 A matches the device number of the terminal telephone). The LK8 information received above is written in position 6 using a known method.
In this state, the corresponding address field is set to the state shown in FIG. 2C for the time being, similar to the operating state in the operation release mode.

Subsequently, when the terminal telephone KT performs an off-hook operation, the central processing unit CC receives this in the same manner as in the case of the above-mentioned LK8 information. Next, the central processing unit CC stores the already pressed line selection button number (hereinafter, general Check whether the line selection button number (simply referred to as the LK number) is set. In this case, since the LK8 information has already been set, the central processing unit CC then checks whether the operation continuation flag is set in the address field (bit number 7) of the button status register KYSTR (route in Figure 3). 1), it is determined that the operation continuation flag is not set (via route 3 in FIG. 3), and the operation continuation flag is set in the address field (bit number 7). As a result, the address section of the button status register KYSTR corresponding to the terminal telephone KT on which the line selection button LK8 has been operated is set to the continuous operation mode as shown in FIG. 2D. Below, the central processing unit CC is the button status register
Based on the LK8 information set in KYSTR in the above operation, the central office line trunk corresponding to the LK8 information
After selecting the COT, control the channel switch network SNW to close the route. In this way, the central processing unit CC executes connection processing such as connecting the terminal telephone KT to the central office trunk COT via the route, the extension interface unit STU, and the route.

When an on-hook operation is performed on the terminal telephone KT due to a call ending, etc., the central processing unit CC sends the on-hook information from the terminal telephone KT to the route, extension interface unit STU, and route in the same way as when the line selection button is pressed. , and controls the communication path switch network SNW to open the route shown in Figure 1 in a known manner and open the central office line trunk.
COT and extension interface unit STU
Perform the recovery process shown in Figure 3, such as restoring the .
The central processing unit CC then stores the button status register KYSTR in the main memory MM on the terminal telephone KT.
In this case, since the operation continuation flag is set in the bit number 7 position of the address section (operation continuation mode in Figure 2 D), the above operation of the address section is continued. The process ends, leaving the flag and LK8 information as is.

Next, when connecting the line corresponding to the same line selection button LK8 from the terminal telephone KT again (Fig. 3 C), the central processing unit CC transmits the off-hook information from the terminal telephone KT in the same manner as in the above case, as shown in Fig. 1. route, the extension interface unit STU and the button status register KYSTR in main memory MM.
Checks the address field corresponding to the relevant terminal telephone KT, and identifies that the operation continuation flag and LK8 information have already been set (operation continuation mode in Figure 2 D) (Routes 1 and 4 in Figure 3)
), the central processing unit CC is connected to the above LK
The connection process similar to that described above is executed based on the 8 information. In this way, the terminal telephone KT can connect to the line corresponding to line selection button No. 8 just by off-hook operation.

(2) When the line selection button is pressed after off-hook (Line selection in the line selection button operation release mode: see Figure 3 B) In Figure 1, when the off-hook operation is performed on the terminal telephone KT, In the same way as in case (1) above, the central processing unit CC receives the off-hook information from the terminal telephone KT, and checks the address field corresponding to the terminal telephone KT in the button status register KYSTR in the main memory MM. Then, it identifies that no LK number is set in the address field and waits for LK information from the terminal telephone KT (via route 2 in FIG. 3).

Subsequently, when, for example, the line selection button LK8 (not shown) is pressed on the terminal telephone KT, the LK8 information from the terminal telephone KT is transferred to the central processing unit CC in the same way as in case (1) above. It is received and written into the address field corresponding to the terminal telephone KT of the button state register KYSTR in the main memory device MM using a known method (the operating state shown in FIG. 2C is set). Thereafter, the central processing unit CC performs connection processing based on the LK8 information in the same way as in case (1), and connects the terminal telephone KT to the office line trunk COT corresponding to the LK8 information.

When an on-hook operation is performed on the terminal telephone KT due to the termination of a call, etc., the central processing unit CC receives the on-hook information from the terminal telephone KT, executes the recovery process, and restores the terminal telephone in the same way as in case (1) above. After restoring the connection from KT to the central office trunk COT, the central processing unit CC checks the address part of the button status register KYSTR in the main memory MM that corresponds to the terminal telephone KT. Since the operation continuation flag is not set in the address section (operation state shown in FIG. 2C), the LK8 information in the address section is cleared and the process ends. That is, the address section is set to the normal state shown in FIG. 2B via route 6 in FIG.

(3) When canceling the operation continuation mode in the on-hook state (see Figure 3 C) In the above operation (1), the line selection button LK8 of the terminal telephone KT is set to the corresponding address part of the button status register KYSTR in the main memory device MM. When the continuous operation mode is set, the continuous operation mode shall be canceled by pressing the central office line hold button, which is one of the function buttons of the terminal telephone KT. The reason why this hold button can be used to cancel the continuous operation mode of the line selection button is as follows. That is, the hold button is generally used to put the terminal telephone in an off-hook state to put the telephone on hold, such as a central office line. On the other hand, since the above-mentioned operation for canceling the continuous operation mode of the line selection button is executed while the terminal phone is in the off-hook state, by identifying the off-hook and on-hook states, the hold button can be used for its original function of holding. This is because it is possible to identify whether the operation was performed or the operation was performed to cancel the continuous operation mode. Furthermore, for the same reason, it is also possible to cancel the continuous operation mode by pressing again the line selection button that has already been set to the continuous operation mode. In any case, the type of button that provides the function of canceling the continuous operation mode does not limit the gist of the present invention.

In FIG. 1, the hold button (not shown) is pressed on the terminal telephone KT in the on-hook state.
When pressed, the hold button information is sent from the terminal telephone KT to the central processing unit CC, and since the terminal telephone KT is in the on-hook state, the central processing unit CC uses the hold button information to issue a command to cancel the continuous operation mode. , and cancels the continuous operation mode set on the line selection button. That is, the central processing unit CC clears the operation continuation flag and LK8 information in the address section of the button status register KYSTR in the main memory MM corresponding to the terminal telephone KT, and ends the process. This will cause the button state register
The corresponding address section of KYSTR is changed from the continuous operation mode shown in FIG. 2D to the normal state shown in FIG. 2B.

(4) Other embodiments The above-described embodiment is an example in which the operation continuation mode is set when the line selection button is pressed before the off-hook operation, but if the order of operations is reversed, that is, when the off-hook The program can also be configured to set the operation continuation mode when the line selection button is pressed after operation. In this case, in the flowchart of Figure 3, when the processing flow flows to route 1, direct connection processing is performed without checking the presence or absence of the operation continuation flag in the button status register KYSTR and setting the operation continuation flag. , and when the flow flows to route 2, the operation continuation flag may be set.

Furthermore, in the embodiments described above, all the processes related to the present invention are performed by the central processing unit and main memory provided in the main body of the electronic exchange or the main unit of the electronic key telephone device, but some or all of these processes are carried out by the terminal. This is also possible with a central control unit and storage on the telephone side. As an example of processing in this case, for example, a line selection state storage area is provided for each line in the storage device of the terminal telephone, and each mode determined within each terminal telephone is stored in the area by the same processing as in the above embodiment. One possible method is to write it.

(Effects of the present invention) According to the present invention, in a terminal telephone (so-called button telephone) having a plurality of non-lock type line selection buttons of an electronic exchange or electronic button telephone device using a storage program control method, the line selection button Since the continuous operation mode can be set and canceled by the user's normal operations on the terminal phone, rather than using a maintenance device to enter a service order, etc., priority should be given to each terminal phone. Setting, changing, and canceling lines can be performed extremely easily and freely, and the effect of significantly improving the operability in connecting lines such as office lines is obtained.
