Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a control operation of a key telephone system having a plurality of telephone terminals.

[0002]

2. Description of the Related Art In recent years, a key telephone system which has a plurality of telephone terminals and is connected to an outside line has become widespread. In such a key telephone system, when a call is made between extension terminals, only the line key corresponding to the extension number needs to be controlled. It is necessary to display the call status for both one or more line keys associated with the line trunk and one or more line keys associated with the extension number used for the call. Here, even if the incoming call is from the same office trunk, if the extension number of the destination is different, the combination of the line key associated with the office trunk to be displayed and the line key associated with the extension is It changes depending on the line trunk used for the line transmission from the same extension terminal. That is, the combination of the line key associated with the office line trunk and the line key associated with the extension number differs for each call. As described above, in order to control a plurality of types of line keys that change in combination for each call, conventionally, each time an event such as outgoing call, incoming call, call, or hold occurs, the line associated with the central office trunk is used. Both the key and the line key constituting the extension number used are read, and control is performed on both. Therefore, even when the line key to be controlled is not changed, as in the case where the call and the hold are repeated, a process of reading out the configuration data occurs every time, and there is a problem that a heavy load is imposed on the process. .

[0003] Further, such a key telephone system can be set in various ways according to its use. However, in such a key telephone system, when an association between an extension number (or an office line trunk) and a terminal (or a line key) corresponding to the extension number (or a line key) is set, it is usually fixed. Therefore, if there is a possibility that an extension number (or line trunk) which is extremely infrequently used will be used, the extension number (or line trunk) is given to one terminal (or line key). ) Must be uniquely associated.
Also, the number of line keys possessed by the multifunction telephone is 10 to 2
In most cases, the number of line keys is not enough to set all possible extension numbers (or office trunks) for the line keys. .

[0004] Therefore, there is a problem that the setting of extension numbers and office line trunks that are less frequently used and less necessary due to the limitation of the number of line keys must be given up.

[0005]

That is, in the conventional key telephone system, even when there is no change in the line key to be controlled, each time a user operation is performed or the state of the line changes, the station is switched. There is a problem in that both the line key associated with the line trunk and the line key associated with the extension number need to be referred to, which is a burden on processing.

Further, in the conventional key telephone system, since the terminal (or line key) and the extension number (or central line trunk) are fixedly associated with each other, the terminal has a limited number of line keys. There is a problem that the number of extension numbers (or line trunks) that can be set to the (or line key) is limited.

SUMMARY OF THE INVENTION The present invention is designed to solve the above-described problems, and the control table, which is the basis for processing control, is adapted as necessary to reduce the processing time. It is an object of the present invention to provide a key telephone system with improved setting flexibility.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention described in claim 1 provides a key telephone system which can be connected to an outside line and has a plurality of telephone terminals in response to generation of a call.

Further, in order to solve the above-mentioned problem, the present invention according to claim 3 has a plurality of telephone terminals which can be connected to an outside line and has one extension number assigned to one or a plurality of terminals. In the key telephone system to be provided, storage means for storing table information in which a plurality of extension numbers are associated with one terminal, and from among the plurality of extension numbers in the table information stored by the storage means, Selection means for selecting an arbitrary first extension number, and after the selection means selects the first extension number, controlling the operation of the key telephone system so as to operate only with the selected first extension number. And a second extension number which is not selected by the selection means among the extension numbers of the table information stored in the storage means is a multi-api run which is shared by the plurality of terminals. When included in the multi-appearance control table for performing control, while the terminal is controlled by the first extension, the multi-appearance control table based on the multi-appearance control table excluding the second extension is used. Control means for controlling the key telephone system to perform control.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

The key telephone system has one or a plurality of line keys associated with an extension number and one or a plurality of line keys associated with an office line trunk. Select and control. The control is a display according to the state of the call, and includes an incoming call display, a call display, and the like. In addition, the correspondence between individual extension numbers (or office line trunks) and line keys is almost always fixed in advance by program setting or the like.

FIG. 1 is a block diagram showing an example of a key telephone system according to the present invention. In this figure, a telephone exchange body 1 connected to a telephone line network N has a central office trunk 11 (11-1,..., 11-m) connected to a plurality of external lines.
A data highway 12 to which detected data is transferred at a high speed; a PCM highway 13; a time switch 14 for connecting each terminal under the control of a CPU; and an extension I / F card serving as an interface to an extension terminal. Fifteen
(15-1, 15-2,..., 15-n), the extension circuit 16 mounted thereon, and the CPU 1 controlling the overall processing operation.
7 and a memory 18 for storing programs and the like for this processing operation. Further, the telephone exchange body 1 is connected to telephone terminals 2 (2-1, 2-2,..., 2-n). The telephone terminal 2 includes an LCD module 32 for displaying each operation information, a PPT 33, a CPU 31 for controlling the whole processing operation, a keyboard 34 for inputting a telephone number, a CODEC 35, and a receiver for a telephone call. 36.

(First Embodiment) In the first embodiment, in the key telephone system as described above, a control table is created every time a call is generated, and line keys are controlled based on the control table.

FIG. 2 is a flow chart for explaining the processing in the present invention. The processing for specifying a line key to be controlled from among the above-mentioned plurality of line keys will be described.

First, when an incoming call or an outgoing call is made, a call is newly generated. Next, when the call is answered, the state of the existing call changes, and finally, when the call is disconnected, the call disappears. The present invention will be described below using these three patterns as examples.

In the flowchart of FIG. 2, first, when an incoming call is received, a new call is generated (S1).
1) It is necessary to specify a line key to be controlled (S12). This process depends on the attributes of the call,
The method of determination is shown in the flowchart of FIG. Specifically, the line keys to be controlled differ depending on the type of the other party (S21), and in the case of a telephone call between extensions, only the line key associated with the extension number is set as the control target (S23).
In the case of a call with an outside line, the line key associated with the office line trunk to be used is also controlled (S22).
For example, if the designated incoming extension number is 201 when receiving a DID call to the office trunk 11, the extension number 2
The line key associated with 01 and the line key associated with the office trunk 11 are to be controlled.

Next, the position information of the line key associated with the extension number 201 and the position information of the line key associated with the office trunk 11 are read from the program setting data (S13). FIG. 4 shows line key position information tables 41, 42, 43, 44 associated with extension numbers.
FIG. 5 shows line key position information tables 45, 46, 47, and 48 corresponding to office line trunks.
This is an example.

From the example of FIG. 1, the port number 1 and the key number 1 are set as the line key positions associated with the extension number 201, and the port number is set as the line key position information associated with the central office trunk 11. 11. The key number 10 is obtained, and the line key is controlled (S14).

After displaying the incoming call for both line keys, the position information of the line keys is stored in association with the call. At this time, in order to identify the call, every time a call occurs, a unique “call number” in the system is acquired and given to each call. In this example, description will be made assuming that a call number 1 is added to a call. Further, a data table for storing the position information of the line key to be controlled corresponding to the call number is prepared. FIG. 6 shows an example of the table.

That is, by using the tables 49, 50, and 51, the line keys “port number 1, key number 1” and “port number 1” obtained in the line key information position storage area corresponding to the call number 1 are stored. 11, key number 10 ".

Next, a description will be given of a procedure for explaining a process in the case of responding to the incoming call described above.

First, when a response is made to the line key that is displayed as an incoming call, it is a change in the state of a call that already exists (S11), so first, the position information of the line key corresponding to the call number is read (S16). . From the previously set table (FIG. 6), "port number 1, key number 1" and "port number 11, key number 10" are read out as line keys to be controlled, and a call display is made for these line keys. Do (S
17). In this way, the processing is dramatically simplified as compared to when a new call is generated.

Finally, a processing procedure when a call is disconnected will be described. When the call is disconnected, the state change of the existing call is the same as that of the previous response, but differs in that the call ends at the end. That is, the line key to be controlled is read from the call number corresponding line key position information table shown in FIG. 6 and the process is the same as in the response until the line key is controlled (turned off). If there is (S18), the table is deleted (S19). Thereby, even if the same call number is generated thereafter, it is possible to prevent the previous line key from being erroneously controlled.

By adopting such a configuration, it is possible to simplify complicated and high-load multi-peer processing.

(Second Embodiment) The second embodiment of the present invention will be described below.
An embodiment will be described with reference to the drawings. In the second embodiment, when associating a plurality of extension numbers with a telephone terminal (or line key) in the control table, it can be set so as to overlap with other telephone terminals (or line keys). Then, even if the extension number not selected of the terminal constitutes a multi-appearance with another terminal, it is not treated as an extension number of the multi-appearance.

FIG. 7 is a basic configuration diagram of multi-appearance control in the key telephone system.

In FIG. 7, the key telephone system includes a multi-appearance control table 53 set for extension number: 200 (52), and line key data 54, 55 for storing the extension number of each line key. 5
6, 57 and 58, and a multi-appearance function is provided by using these.

That is, extension number: 200 from other extension
When a call is made to the telephone number, the position of the line key table for ringing the incoming call is specified with reference to the multi-appearance table 53. Also, when a call is made from one of the multi-appearance line keys to be configured for extension number: 200, the line key table recognizes that this call is for extension number: 200, and the multi-appearance control table By referring to 53, another line key is displayed in use.

Here, a description will be given below of newly provided parameters that enable a plurality of extension numbers to be assigned to one line key.

FIG. 8 is a configuration diagram of multi-appearance control using the second embodiment of the present invention.

In this example, the line key of the terminal accommodated in the port 03 is the extension number 200 and the extension number 3
A procedure for switching the operation of 00 will be described. FIG. 8 shows an example in which the line key operates as extension number: 200.

First, the control table stored in the memory 18 of FIG. 1 contains information on the line key (port number and line key number) set to realize the multi-appearance corresponding to each extension number 200, 300. 61 and 63 are provided. Further, each of the line keys has parameters 64 and 62 indicating whether or not each line key operates in the own multi-appearance group. When a call is made from the line key with this extension number,
When an incoming call is received for this extension number, the CPU 17 controls the processing so that only the line keys for which the parameters 62 and 64 are set to "subordinate" are processed.

These control tables are stored at the time of data setting. In an initial state, one line key is set so as to be dependent only on a multi-appearance group configured for one predetermined extension group. Is configured.

This control table is provided with a data area 65 indicating all extension numbers set corresponding to each line key, and these contents are set when data is set. That is, in this example, the line key: 1 of the terminal having the port 03 is the extension number 200 and the extension number 30.
It will have two extension numbers of 0.

Next, the operation of the line key of the port 03 is changed from the operation of the extension number 200 to the extension number:
The case of switching to the operation as 300 will be described with reference to FIG. The switching trigger may be a special number for changing the extension number preset for the system, or may be an operation using a function key.

First, by inputting a special number or a function key,
Line key data 65 stored for the line key: 1
From the operation of the extension number: 200 as shown in FIG.
Change to 300 operation.

Next, in order to change the multi-appearance control table 63 to which the line key 1 belongs, the multi-appearance control configured for all the extension numbers set for the line key 1: Make changes to the table. In this example, the line key: 1 is the extension number: 200
And the extension number: 300, the data is changed in the multi-appearance control table for each extension number.

The change of the multi-appearance control table is performed only by changing the subordinate data 64 in the multi-appearance control table corresponding to the operated line key. That is, in this example, the extension number:
In the multi-appearance control table 73 configured for 200, the dependent data of port: 03, line key: 1 is changed from dependent to non-dependent as indicated by the parameter 74 of the table 73 in FIG. This is performed by changing the subordinate data of the port: 03 and the line key: 1 from the non-subordinate to the subordinate as shown in the parameter 72 of the table 71 in FIG.

Thus, port: 03, line key: 1
Can be switched from extension number: 200 to extension number 300. FIG. 9 shows the configuration after switching.

(Third Embodiment) The example in which a plurality of extension numbers and line keys are associated with each other by using a control table set in advance has been described. An embodiment in which the multi-appearance control table is automatically and dynamically changed will be described below.

Normally, a line key associated with a CO trunk has a fixed correspondence with a CO trunk.
When providing a service such as a CR function that may change the trunk of the connection destination by dialing input by the user, the line key cannot be used continuously due to the change of the CO trunk of the connection destination. . Therefore, CO
If the trunk is to be changed, it is necessary to transfer the operation to the line key or an empty extension key corresponding to the changed CO trunk and release the previously captured CO trunk and line key. However, the operating terminal does not always have a CO line key or an empty extension key corresponding to the CO trunk captured by the route selection, and may not be able to provide the LCR function. What was done to avoid this situation was
This is a third embodiment according to the present invention.

FIG. 10 is a block diagram of the multi-appearance control according to the present invention. The line key: 1 of the terminal accommodated in port: 01 and the line key: 1 of the terminal accommodated in port: 02 are CO An example in which the trunk is associated with 1 is shown. Here, the multi-appearance control table 81 for the dedicated line trunk: 2, the CO trunk:
One multi-appearance control table 82 is shown. In this state, when there is an incoming call to the CO trunk 1, an incoming call is displayed for the line key,
Response processing is performed by pressing the line key. Also, CO
When the line key is pressed while the trunk 1 is empty, the operation of capturing and transmitting the CO trunk 1 is performed.

FIGS. 8 and 9 show the basic structure.
Is the same as the second embodiment described above, except that it is not necessary to register all terminals in advance in a multi-appearance control table configured for all trunks, The difference is that the key has a data area for storing changed data when the operation of the line key is switched. Normally, as shown in FIG. 10, there is no corresponding trunk data in the changed data area 83. Further, each multi-appearance control data constitutes a program so that a data area for storing an accommodation position of an arbitrary line key can be added or deleted.

FIG. 11 shows that, as described above, while the user is dialing the other party number from the CO trunk: 1,
FIG. 10 is a configuration diagram after it has been found that passing through a dedicated line is the cheapest and a dedicated line trunk: 2 is captured.

The line key is separated from the control table 85 of the multi-appearance configured for the CO trunk 1 as non-dependent, and as a result, the other multi-appearance configuration configured for the CO trunk 1 is performed. The line key becomes empty. The changed data area of the line key stores the data after the change, that is, the information associated with the dedicated line trunk: 2. In addition, the line key data is added to the control table 84 of the multi-appearance configured for the dedicated line trunk: 2,
As a result, the other multi-appearance configuration line keys configured for leased line trunk: 2 will have a busy indication. In addition, it is possible to edit the dial according to the selected route, in addition to the function of storing the dial that has been transmitted to the network and, if the connection destination trunk is changed, By providing the function and the function of transmitting the edited dial from the trunk after the connection is changed, it is possible to change the trunk to be captured while using the same line key.
The CR function can be provided.

Further, after the end of the call, a function for automatically returning to the state before the change, that is, the state shown in FIG. 10, is provided so that the user can perform a normal operation without performing a troublesome operation. You can go back.

By adopting such a configuration, it becomes possible to automatically and dynamically change the multi-appearance control data by the provided service.

[0048]

As described above in detail, according to the first embodiment of the present invention, when a call is generated, the line key associated with the central office trunk and the line key associated with the extension are called. Then, by storing only the stored line key as a control target, it is possible to provide a key telephone system capable of simplifying the processing of the multi-appearance function and shortening the processing time. .

Further, according to the second and third embodiments of the present invention, an extension number (or an office trunk) that is used less frequently is
By sharing with a terminal (or line key) associated with another extension number or trunk, it is possible to provide a key telephone system capable of increasing the number of extension numbers that can be set in the terminal.
