Abstract

PURPOSE:To control a call from a transmission side based on various calls control items by previously registering the scripts not less than one but less than the fixed number of scripts from an extension subscriber's telephone set to PBX so that its contents can be updated and correspond to a script number. CONSTITUTION:In a state where the scripts are previously registered from the respective extension subscriber's telephone sets 1 and 2 to PBX 3 as ones corresponding to the script numbers, when the transmission call including a script specification special number, a script number and a called extension subscriber's telephone set number is dialed to PBX 3 from the telephone set 1, PBX 3 can control the transmission call in a prescribed way based on not less than one call control items included in the script corresponding to the script number. Consequently, without regard to what state the incoming call extension subscriber's telephone set is in before transmission, the call from the transmission side can be controlled based on the various calls control items.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call control method in a private branch exchange, and in particular, in a state where a script has been pre-registered in each private branch exchange from a private branch exchange telephone, a script number and a target number are transmitted from the private extension exchange telephone. When an outgoing call including the call extension telephone number is present in the private branch exchange, the private branch exchange sets the incoming extension subscriber telephone of the outgoing call based on one or more call control items included in the script corresponding to the script number. The present invention relates to a call control method by script pre-registration that controls incoming calls to the.

2. Description of the Related Art Private branch exchange (hereinafter referred to simply as PBX)
Various services such as camp-on, call-waiting, call forwarding, and call forwarding are known as services related to extension extension telephones. Of these, for example, in the case of the camp-on service, the outgoing extension subscriber telephone side knows that the incoming extension subscriber telephone side is busy, and the outgoing extension subscriber telephone side uses either the hooking method or the timing method. After the camp-on registration is done, the system waits in the on-hook state, and then the PBX confirms that both parties are free, and then automatically calls both parties. On-service is available. By the way, the hooking method here is a method of performing camp-on registration by hooking (temporary on-hook state) + special number dial (for example, "digital PBX").
Introduction to Battle Guide "(September 30, 1988, Co., Ltd.
Denkaku Shoin, pages 68, 69)), and
The timing method is a method of automatically performing camp-on registration by waiting for a certain period of time in an off-hook state.

Further, regarding call waiting,
This is the same as that which has already been put to practical use in the public telephone network as a so-called “catch phone service” (NTT (registered trademark) service name: Telephone Guide issued by NTT, page 222). Is something
When the called party in the busy state hooks on the basis of the incoming call notification sound from the exchange, it can be connected to the call from the third party, and by hooking again in this state, the call is put on hold. It is possible to return to the busy state with the other party. Regarding this call weighting, for example, Japanese Patent Laid-Open No. 4-9154
The one described in Japanese Patent No. 6 is known.

[0004]

However, in the conventional PBX, as can be seen from the camp-on registration method required for receiving the above-mentioned camp-on service, the registration is made after the call is made, that is, the extension of the incoming call is joined. It is the first time that the call is made from the originating extension subscriber telephone side, knowing that the telephone is busy, and the originating extension subscriber telephone side is irrespective of the state of the incoming extension subscriber telephone before making the call. The reality is that you cannot register for camp-on beforehand. In other words, until now, regardless of the state of the receiving extension telephone set before making a call, various call control items are set in advance, and calls from the calling side are made based on these call control items. It means that you cannot control. An object of the present invention is to provide a call control method by script pre-registration that can control a call from the caller side based on various call control items regardless of the state of the incoming extension subscriber telephone before making a call. .

[0005]

SUMMARY OF THE INVENTION Basically, one or more scripts within a fixed number from each extension subscriber telephone set are provided as PBXs whose script contents can be updated and correspond to script numbers. If the outgoing call including the script-specified special number based on dialing, the script number, and the called extension subscriber phone number from the outgoing extension subscriber telephone is in the PBX while being registered in advance, This is achieved by controlling the incoming call of the outgoing call to the incoming extension line telephone based on one or more call control items included in the script corresponding to the script number.

[0006]

Operation: From each extension telephone set, within one fixed number, one or more scripts can be updated,
In addition, the script number is registered in advance with the PBX. If the outgoing extension subscriber telephone dials an outgoing call including the script specified special number, script number, and called extension subscriber telephone number to the PBX while the script is registered in advance, the script number is set in the PBX. The outgoing call can be controlled in a predetermined manner based on one or more call control items included in the corresponding script.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. First, the PBX according to the present invention will be described with reference to FIG.
Shows the PBX and its periphery, and FIG. 3 shows the internal structure of the PBX as an example. As shown in the figure, the PBX 3 has a voice mail device 4 and a large number of extension subscriber telephones 1 and 2 accommodated in a switch 3-1 via a line interface 3-2. 1 can be connected. How the two arbitrary ones are connected via the switch 3-1 is controlled by the central controller 3-5 under the control of various exchange control programs stored in the main memory 3-4. This is achieved by controlling the connection state of the switch 3-1 via the switch 6. The main storage device 3-4 also stores various types of subscriber data corresponding to the extension subscriber telephones 1 and 2 as being updatable, and these various types of subscriber data are periodically transmitted via the data storage control unit 3-3. The latest data is saved and stored in the nonvolatile data storage unit 3-7. In this way, when various subscriber data are regularly saved and stored in the non-volatile data storage unit 3-7, the PBX 3 falls into the system down due to some failure occurrence, and the PBX 3 is restored due to the subsequent failure recovery.
3 is restarted, the nonvolatile data storage unit 3-7 loads the main storage device 3-4 together with various exchange control programs, and then the exchange control process is restarted, so that the exchange control process is started. The exchange control process can be restarted while the above continuity is ensured. By the way, when the voice mail device 4 does not answer the call from the PBX 3 due to absence or the like even though the called extension telephone is not busy, the voice mail device 4 sends a message addressed to the called extension telephone to the calling extension telephone. It is provided to register from.

In the general PBX3, the exchange control process is performed as described above. In the present invention, however, a script including one or more call control items is sent from each of the extension telephone sets 1 and 2. It is supposed to be pre-registered in the PBX 3 as renewable. The scripts from the extension subscriber telephones 1 and 2 are stored in the main storage device 3-4 together with various subscriber data corresponding to the extension subscriber telephones 1 and 2 and, like the various subscriber data, the nonvolatile data storage unit 3
7 is regularly saved and stored in the main memory device 3-4 from the nonvolatile data storage unit 3-7.

The script will be described in detail below. That is, FIG. 1 shows the concept of the script according to the present invention. In this case, management block areas 5 and 6 corresponding to the extension subscriber telephones 1 and 2 are provided in advance on the main storage device 3-4, and the extension subscriber telephones 1 and 1 are respectively provided in the management block areas 5 and 6.
Various subscriber data corresponding to 2 are stored as updatable, and the script registration tables 9 corresponding to the extension telephone sets 1 and 2 are pre-registered within a fixed number and as updatable. . For example, if ten scripts can be registered as script numbers 0 to 9 from each of the extension telephone sets 1 and 2, a maximum of 10 script registration tables 9 can be registered in each of the management block areas 5 and 6. is there. In other words, in each of the management block areas 5 and 6, the script registration table 9 corresponding to the script numbers 0 to 9 is pre-registerable by the extension subscriber. The extension subscriber, with the support of the PBX 3, sends a script corresponding to the script number to the empty script number to the desired script registration table 9
When pre-registering as, the empty script number is assigned to the pointer 7 in the management block areas 5 and 6,
The script registration table 9 corresponding to the script number is set on the pointer array 8 to indicate the setting position, and the script registration table 9 having the desired content is set at the setting position. On the other hand, when a script number is dialed by a calling extension subscriber in response to a call, the script number is assigned to the management block area 5,
The pointer 7 in 6 is set to indicate the existence position of the script registration table 9 corresponding to the script number on the pointer array 8, and the setting contents of the script registration table 9 are referred to The call is subsequently processed according to the setting contents of the script registration table 9. Incidentally, in the example shown in FIG. 1, the script registration table 9 corresponding to the script number 0
However, the script registration table 9 corresponding to the other script numbers 1 to 9 can also be set in the same format. However, it is undeniable that this format will become more diverse as the number of service types increases.

First, the script pre-registration will be described in detail below with reference to FIGS. 4 to 8 showing each part of the registration processing flow. That is, in this example, the extension telephone set 1 to the script number 3
"Transfer suppression on the receiving side", "Camp-on registration when the receiving side is busy", "Ring 10 times"
It is assumed that a script including each "redial (recall) every 30 minutes for three times in the case of no response" as a call control item is pre-registered.
In other words, the script consisting of those call control items is
Even if a transfer destination (automatic transfer destination or call forwarding destination) is set on the called extension telephone set, if you try to force the call to the called extension subscriber phone after ignoring the forwarding destination When the called extension telephone set is busy, the camp-on registration is performed unconditionally, while when the called extension telephone set is not busy, it means that the called extension telephone set is called. Moreover, at the time of making the call, the ringing tone is sounded up to 10 times for the first call. However, unless the called extension telephone set answers the call, thereafter, the call is redialed every 30 minutes for a maximum of 3 times. This means making a call again.

In the pre-registration, if the extension subscriber telephone 1 dials the script registration special number [96], the PBX 3 starts the script registration operation according to the flow shown in FIG. (Process 100). Then, the guidance "Please send the script number" is played (process 101), and the script number input waiting state is entered (process 102). If "3 #" is input as the script number from the extension subscriber, the script number "3" is registered in i (step 103), and the script registration table 9 indicated by the i The contents are to be cleared (Processing 10)
4).

Next, the guidance "Please input the script" is played (process 105), and the script input waiting state is entered (process 106). Here, the script command to be input is a command "01 #" that specifies automatic transfer suppression, and a command "02" that specifies processing during busy.
# ", The command" 03 # "that specifies the processing at the time of calling,
Alternatively, the subsequent processing is divided depending on which of the commands "##" that ends the script registration is input. However, if a command other than the above is input,
Guidance "Incorrect input" is played (Process 152)
→ Process 153). Here, it is assumed that the guidance "Please enter a script" prompts the extension subscriber to input a script command "01 #" for designating the automatic forwarding suppression on the called side (process 107). in this case,
When the content of the setting item 10 shown in FIG. 1 is already “present”, it is considered that the setting has already been made, and the guidance “Incorrect input” is sent (Process 108 → Process 152 → Process 1
53). If the content of the setting item 10 is “absent”, the content is set to “present” and the script input waiting state is entered (process 108 → process 109 → process 106). In this state, if the script command "02 #" that specifies the process during busy is input next (process 110), the process is performed in the same manner as the above according to the contents of the setting item 11. (Process 111 → Process 152 → Process 153 or Process 1
11 → process 112 → process 113). Furthermore, setting item 11
Is set to "Yes", and in the script input waiting state after that, the input script command specifies the command "04 #" that specifies the camp-on process, and the voice mail process when busy. Command "05
Depending on whether "#" or the command "06 #" that specifies redial processing when busy, the subsequent processing is divided, but in this example, in the above script input waiting state, the extension subscriber The script command "04 #" designating the camp-on process is input, and the setting item 14 is set as "present" (process 114 → process 115 → process 116). If anything other than the above three commands is entered,
Or, even if any of these three commands is input, if it is already set as "Yes",
The guidance “Incorrect input” is played (process 152 → process 153).

Incidentally, in the above-mentioned script input waiting state,
When the subscriber inputs the script command “06 #” that specifies the redial process during busy and the setting item 16 is set as “Yes” (process 120 → process 1
21 → process 122), and the process relating to the redial shown in FIG. 8 is continuously performed. As shown in Figure 8, if the script command "n *" that sets the redial interval to n minutes is not entered correctly, the guidance "Incorrect input" will be played (Process 1
24 → Processing 152 → Processing 153), if the correct input is made, the input redial interval value “n” is set in the setting item 17, and the script input waiting state is set (process). 124 → process 125 → process 126). In this state, if the script command “t *” that sets the number of redials to t is not input correctly, the guidance “Incorrect input” will be played (Process 127 → Process 152 → Process 153). If the correct input is made, the input redial count value “t” is set in the setting item 18, and the script input waiting state is set (process 127 →
Process 128 → process 106). By the way, the script of script number 3 needs to include each of "ringing tone 10 times" and "redialing every 30 minutes for three times in case of no answer" as call control items. Yes, for this reason, the script command "0" that specifies the processing at the time of calling
When 3 # ”is input in the script input waiting state (process 106 → process 107 → process 110 → process 130)
→), “Present” needs to be set in the setting item 12 (process 132). Then, in the script input waiting state, the number of ringing tones is m (m = 1 in this example).
If the script command “m *” for setting 0) times is correctly input, the number of ringing sounds “m” is set in the setting item 13 and the script input waiting state is set. (Process 133 → Process 134
→ Process 135 → Process 136). In this script input waiting state, the input script command is a command "07 #" for designating a voice mail process at the time of calling or a command "0" for designating a redial process at the time of calling.
The subsequent processing is divided depending on whether it is "8 #". In the script in this example, "redial (recall) every 30 minutes for three times in the case of no response" is called. Since it needs to be set as a control item, the command "08 #" is used instead of the command "07 #".
Is to be entered. Command Command “0
If 8 # ”is entered,“ Yes ”is set in the setting item 20.
Is set (process 137 → process 143 → process 144 → process 145). When the script command “n *” that sets the redial interval to n (n = 30 in this example) is input correctly in the subsequent script input waiting state, “n” is set to the setting item 21. (Process 146 → process 147 → process 148). Further, when the script command “t *” for setting the number of redials to t (t = 3 in this example) is input correctly in the subsequent script input waiting state,
The input redial count value “t” is set in the setting item 22 and is in a script input waiting state (process 149 → process 150 → process 151 → process 106). If a script command "07 #" that specifies voice mail processing is input in place of the above command "08 #", a message addressed to the extension telephone of the receiving side is sent from the extension telephone of the calling side. In order to register, “present” is set in the setting item 19.

Finally, when a command "##" for terminating the script registration is input in the script input waiting state, a series of pre-registration processing is performed by sending the guidance "script registration is completed". The process is terminated (process 106 → process 107 → process 110 → process 130).
→ process 140 → process 141 → process 142). In the above example, the script is registered only by using the number keys, * key, and # key provided on the ordinary telephone, but the script can be registered by the multi-function telephone to improve the operability. .

The preregistration process has been described above by taking the script of script number 3 as an example. However, different call control contents can be set in the same manner for each of the scripts of other script numbers. For example, the calling side can select the script having the optimum call control content according to the called side and optimally control the call to the called side. Now, the case of controlling a call based on the script pre-registered as described above will be described in detail with reference to FIGS. 9 to 12 showing each part of the call control processing flow.

In other words, for convenience of explanation, in this example, when the extension subscriber telephone 1 of FIG. 1 makes a call to the extension subscriber telephone 2, the script number 3 is selected and designated, and then the call is made. The call control operation will be described first. As shown in FIG. 9, first, from the extension telephone set 1, (script designated special number)-(script number)-(remote extension number) (example:
If [94]-[3]-[XXXX] is dialed, the PBX 3 accepts the call and starts the call control process (process 201 → process). 202). At the start, whether or not there is a script designated special number is first determined, but if there is no script designated special number, normal call control processing is performed (process 203 → process 204 → process 221). If the script designated special number is dialed, the script contents corresponding to the script number 3 already registered in advance, that is, the script registration table corresponding to the script number 3 is registered.
Bull 9 is referred to, and first, the setting content of the setting item 10 is determined (process 203 → process 20).
5). If it is confirmed that the setting content is “present”, regardless of whether or not the transfer destination is set on the receiving side, the destination is the extension subscriber telephone set 2 and the destination is It is determined whether or not the busy state is set (process 205 → process 206). Also, if
If the setting is not "Yes", it is judged whether the transfer destination is set or not, and only if the transfer destination is set.
It is determined that the callee is a callee, and whether the callee is busy is determined (step 205 →
Process 210 → process 211 → process 206). In this example, since "Yes" is set as the setting content, the destination is unconditionally the extension subscriber telephone set 2.

After that, the processing is divided depending on whether the called side (the subscriber's telephone set 2 or the transfer destination thereof) is busy. In the busy state, and when the setting content of the setting item 11 is “none”, the busy tone is transmitted to the extension telephone set 1 (process 206 → process 207 → process 208 →). Process 211). Further, as shown in the script contents in this example, when the busy state is set and the setting content of the setting item 11 is “Yes”, the busy time designation processing routine is followed. The call control process is performed (process 207 → process 209). In the busy-time designation processing routine, the setting content of the setting item 14 is first determined (processing 222 → processing 223). As the script content in this example shows, if the setting content is "Yes",
The camp-on process is executed (process 223).
→ Process 224 → Process 233). Further, if the setting content is "absent", the setting content in the setting item 15 is judged, and if the setting content is "present", the extension subscriber telephone set 1 has a voice mail device. 4 is connected and a message addressed to the destination is registered (process 223 → process 225 → process 226 → process 23).
3). At that time, if the setting content is "none",
The setting content of the setting item 16 is to be determined (process 225 → process 227). If "no" is set as the setting content in the setting item 16, the call control processing is ended without any redial processing (processing 227 → processing 233), but the setting content is "present". Is set, it means that redial processing is being performed. In this redial process, the setting item 1 can be set up to the maximum number of times set in the setting item 18.
The redial is made to the destination at every redial interval set in 7. (Processes 227, 229,
230, 231, 232, 229).

On the other hand, returning to the explanation, when the called party (the subscriber's telephone set 2 or the transfer destination thereof) is not in the busy state, the setting contents of the setting item 12 relating to the calling process are judged. (Process 206 → Process 212).
When the setting content is "none", the ringing tone is normally sent to the called party (process 212).
→ process 213 → process 221). However, when the setting content is “present”, as the script content in this example shows, the ringing tone is received up to the maximum number of times set in the setting item 13 (10 times in this example). Will be sent first, but if the called party answers the call,
After that, while normal processing is performed, if the called party does not respond to the call, the call processing is performed according to the call time designation processing routine (processing 212, 214, 21).
5,216,217,218,219,220,22
1). In the call-time designation processing routine, first, the setting contents of the setting item 19 relating to the voice mail processing at the time of call are judged (processing 235). If the setting content is "present", the voice mail device 4 is connected to the extension telephone set 1 and the message addressed to the destination is registered (process 236 → process 243).
At that time, if the setting content is “none”, the setting content of the setting item 20 related to the redial process at the time of calling is determined (process 235 → process 23).
7). If the setting content of the setting item 20 is “absent”, the call processing is terminated as it is, but if it is “present”, as shown by the script content in this example, 3
Redial (recall) processing is performed every 30 minutes for a number of times (processing 238, 239, 240, 2).
41,242,243).

The present invention has been described above. However, it is desirable that the contents of each script preregistered in the PBX 3 be in a state where they can be confirmed at any time by the extension telephone sets 1 and 2. The contents can be easily confirmed by dialing (script confirmation special number)-(script number) from each of the extension telephone sets 1 and 2. For example, when "3" is dialed as the script number, the above-mentioned script content is changed to voice guidance such as "script number 3, transfer suppression 01, busy time process 02, camp on 0.
4, call process 03, 10 times, redial process 08, 3
Every 0 minutes, 3 times is played, and the content is known by listening to it. If the phone is a multi-function phone, the script confirmation key is simply operated,
On the display, [3 # / 01 # 02 # 04 # 0
3 # 10 * 08 # 30 * 3 * ##] is displayed, and the content of the script corresponding to the script number 3 is known from this display.

[0020]

As described above, according to claims 1 and 2, the call from the calling side is treated as various call control items regardless of the state of the called extension telephone set before the call is made. It can be controlled based on the original.
