Corresponds to 3.

Before entering into the explanation of the emergency transfer service under the above system configuration, the creation of a list of destinations to be transferred to when the destination is unknown will be explained.

The purpose of creating this list is to increase the probability of receiving calls that are so urgent that the above-mentioned conventional transfer service alone cannot achieve the purpose.

In the following explanation, the signal sequence in the present invention between the terminal device and the exchange is also explained in the [Prior Art] section above, in which various signals are exchanged in command format via the 2B+D channel. Therefore, in order to avoid redundant explanations, we will not provide a detailed explanation of each signal transmission/reception, but it should be understood that signals are transmitted and received in that signal transmission/reception format.

From the menu displayed on the screen of the display device 88 in response to the operation of the menu display key belonging to the operation key group for the emergency forwarding service on the keyboard of the display device 88, select “Emergency forwarding destination registration”. ” by operating the selection key. Then, input the transfer destination terminal number by operating the numeric keys. An emergency transfer destination registration request is sent via the 15DN transmission control device 72 to 2B+D, which is formed between the private branch exchange switch section 2 and the private branch exchange switch section 2.
transmitted to the exchange control processor 4 via the channel,
The request is then given to AP6 (20 in Figure 3).
0). The request includes emergency transfer destination registration request information and a registration request source terminal number.

The application management unit 50 of the AP 6 that received the request issues a transfer service application (for example, application program #1 as described above) because the request is an emergency transfer destination registration request. , and pass the emergency transfer destination registration request information and the registration request source terminal number to it. The request determination unit of the transfer service application (62A in Figure 2, 63 in Figure 5)
A) makes a request determination and passes control to the emergency transfer destination registration/deletion unit 68 (see 71 in FIGS. 2 and 5).

The emergency transfer destination registration/deletion section 68 first transfers a transfer destination inquiry to the registration request source via the exchange control processor 4 and the exchange switch section 2. The emergency transfer destination registration/deletion unit 68, which has received the required number of transfer destination terminal numbers from the registration requesting terminal in response to this via the exchange switch unit 2 and the exchange control processor 4, sends the transfer destination terminal numbers. When the destination of the hard disk is unknown, it is registered in the transfer destination list 11 (FIG. 6). Note that the transmission of the transfer destination terminal number from the terminal is also performed by operating the numeric keys on the keyboard, as described above.

After the registration is completed, a completion notification is sent from the emergency transfer destination registration/deletion section 68 to the registration request source via the exchange control processor 4 and the exchange switch section 2. In response, the terminal returns an emergency transfer destination registration completion message to the emergency transfer destination registration/deletion unit 68. When the emergency transfer destination registration/deletion unit 68 sends a completion response to the registration request source, the path that was previously set in the exchange is released.

Assume that after the exchange has prepared the list of forwarding destinations when the destination is unknown as described above, a call requesting an emergency forwarding service different from the conventional forwarding service occurs at an extension terminal (or central office line). This call is made by operating the selection key on the keyboard of the corresponding item "Emergency Communication" on the menu displayed on the screen of the display device 88 to indicate that the call is an emergency call. This call is presented to the switch including emergency diversion service request information (100 in Figure 4).
. This call is handled by the terminal line corresponding section in the exchange switch section 2 (
(not shown) and the detection information is provided to the exchange control processor 4. This detection information also includes emergency transfer service request information. The exchange control processor 4
to the application management unit 50 of the AP 6, the calling side terminal number and the called side terminal number are given as in the case of the conventional transfer service, and emergency transfer request information is given instead of the transfer service request information in the conventional transfer service. (102 in FIG. 4), and the transfer service application (see FIG. 11) is activated. Since the call is a request for emergency transfer service, the request determination section 62A therein passes control to the emergency transfer destination determination section 69 (see 73 in FIG. 5).

The emergency forwarding destination determination unit 69 first searches the forwarding destination list when away from the desk (104 in FIG. 4 (Part 1)), and the receiving terminal number is registered there, as in the case of conventional forwarding services. If registered, enter the terminal number corresponding to that number in addition to the calling terminal number (YES in 106 in Figure 4 (Part 1)), or if not registered, enter the calling terminal number in addition to the calling terminal number. Sends the terminal number to the exchange control processor 4 (112 in Figure 4 (Part 1)), forms a channel to that terminal, and sends the calling terminal number and emergency call display information to that terminal (see Figure 4 (Part 1)). 1), the terminal display screen displays the calling terminal number and the fact that the incoming call is an emergency call (116 in FIG. 4).

If a response to the call is detected within a predetermined time (for example, within 8 seconds) by the response terminal line corresponding section (not shown) of the exchange switch section 2 (No. 118 in FIG. 4 (Part 2)
), and performs incoming call processing to the responding terminal (120 in FIG. 4 (Part 2)).

If not detected (Y of 118 in Figure 4 (Part 2)
ES), an emergency transfer determination activation request is given from the exchange control processor 4 to the emergency transfer destination determination unit 69 of the AP 6 (122 in FIG. 4 (Part 2)). The emergency transfer destination determination unit 69 sequentially reads out the destination unknown transfer destination list on the hard disk from the beginning (124 in FIG. 4 (part 2)). When it is determined that the readout is not registered (No in 126 in FIG. 4 (Part 2)), the emergency transfer destination determination unit 69 notifies the originating terminal via the exchange control processor 4 that connection is not possible. (128L connection processing request in Figure 4 (Part 3)) is sent to the exchange control processor 4 (130 in Figure 4 (Part 3)). The destination terminal number is also given to the exchange control processor 4.

When there is registration (YE of 126 in Figure 4 (Part 2)
S) A presence inquiry is made to the terminal corresponding to the read terminal number (132 in FIG. 4). At the time of the inquiry, the terminal number can also be transferred to that terminal. The own terminal number is displayed on the display device screen of that terminal (134 in FIG. 4 (Part 2)). If the presence response from the terminal is not returned within a predetermined time (for example, within 8 seconds) (136, 138 in Figure 4 (Part 2)), the next registration from the list of forwarding destinations when the destination is unknown This causes the number to be read out (No. 140 in FIG. 4 (Part 2)). Even if all the terminal numbers registered in the transfer destination list 11 when the destination is unknown are read out and the above-mentioned presence response is not returned within the predetermined time to the presence inquiry for the last terminal number, the above-mentioned The same processing as in the case of unregistration is taken.

If there is a presence response (YES in 140 in FIG. 4 (Part 2)), the time transfer destination determination unit 69 sends a connection request to the exchange control processor 4 (FIG. 4 (Part 2)). 142). This connection request includes the originating terminal number and the terminal number corresponding to the room presence response. The exchange control processor 4 that has received the connection request sets a path between the originating terminal line correspondence section and the presence response terminal line correspondence section in the exchange switch section 2 (Fig. 4 (Part 2)). 144).

Additionally, if the terminal user no longer desires all or part of the emergency call processing by referring to the list of forwarding destinations when the destination is unknown for emergency calls, the terminal user will display a service selection menu on his or her terminal display screen. , select the item "Delete emergency forwarding destination" using the selection keys on the keyboard, and enter the terminal number from which you wish to delete emergency calls using the numeric keys. The prosperity, time forwarding destination deletion request and deletion desired terminal number from that terminal are given to the application management unit 50 of the AP 6, the forwarding service application is started, and the emergency forwarding destination is registered based on the determination result by the request determining unit 62A. /The deletion unit 68 is controlled, and the receiver deletes all or part of the registration in the transfer destination list when the destination is unknown according to the terminal number that the recipient wants to delete (302 in FIG. 7).
). When the deletion is completed, a sequence for completing the deletion is carried out between the emergency forwarding destination registration/deletion unit 68 and the deletion request source, that is, the same sequence as in registration 2 (emergency forwarding destination registration/deletion unit 68
8 to the deletion requestor, the deletion requestor to the emergency forwarding destination registration/deletion section 68, and the emergency forwarding destination registration/deletion section 68 to the deletion requesting source. A sequence (consisting of a termination response) is generated.

In addition, in the above embodiment, in the case of incoming call forwarding based on the forwarding destination list when the destination is unknown, the determination as to whether or not a response is returned from the calling terminal within a predetermined time is transferred to the AP side, and the subsequent processing is performed. good.

〔Effect of the invention〕

As described above, according to the present invention, while inheriting the conventional transfer service function, it is possible to increase the probability that a highly urgent call made by a caller to a person desiring to receive a call will be received by the person desiring to receive a call. Further, the addition of functions for this purpose is slight and does not complicate the human ink face.
