Abstract

PROBLEM TO BE SOLVED: To obtain a system that does not waste charge and time by restricting it that an incoming call reaches a called party when a telephone number only is coincident with that of the called party even if the called party is out. SOLUTION: A speech possible state of a user and a reply operation at the arrival of an incoming call to a user in a speech disabled state are registered by each individual number of the user in cross-reference with a telephone number of a subscriber receiving an incoming call to a TUPN relating information table 50. When receiving an incoming call, a controller 30 requests to a personal number of a called party for a caller subscriber so retrieve whether or not its reply is registered in the TUPN relating information table 50. When the reply is registered, the controller 20 controls a speech path system unit 20 to connect to the incoming call when the user is in a speech enable state at present according to contents of the TUPN relating information table 50 and starts a reply incoming call system service depending on a value of SIN registered in the TUPN relating information table 50 in the incoming disabled state. The reply operation includes the incoming call system service such as announcement of absence, transfer of the incoming call, and recording of caller message.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an incoming connection control device and an incoming connection control method.

[0002]

2. Description of the Related Art Examples of conventional incoming connection control systems of this kind are disclosed in Japanese Patent Application Laid-Open Nos. 58-66455, 4-70046, and 5
-68097 and JP-A-6-86352. In this conventional incoming connection control method, when there is an incoming call to the receiving subscriber's terminal, incoming call control such as identification information of the calling subscriber such as calling number, or a password for the receiving subscriber's (called terminal) telephone number. Decision information (TRDI: Terminati
ng Restriction Deciding Information) to allow or deny incoming calls.

[0003] That is, incoming call restriction decision information, such as the number of permitted calls for each subscriber's telephone number and personal identification number, is registered in the communication network (exchange station) in advance, and when there is an incoming call to this subscriber, The incoming call restriction judgment information sent from the calling subscriber is compared with the registered incoming call restriction judgment information. As a result, if they match, the incoming call is permitted, and if not, the incoming call is rejected. .

Japanese Patent Application Laid-Open No. 4-27258 discloses a method of registering incoming connection service control information so that a subscriber can respond to an incoming call during, for example, a telephone call or communication. The calling control incoming connection method to be attempted is described.

[0005] In this method, a service of a called subscriber is designated and executed by a password from the calling subscriber. This security code is service-compatible, and the calling subscriber must know the security code-to-subscriber service support and enter it for the purpose of specifying and executing the service. State in which communication cannot be performed with the user terminal (in short, after determining the terminal state, the Busy state
), It must be input after being notified by the BusyTone connection. As a result, the service that the calling subscriber wants to execute is performed by the input password.

[0006]

However, the conventional incoming connection control system has the following problems.

[0007] First, a number of useless calls called "calls permitted to terminal users who cannot make calls" cannot be ignored even if they are considered on a daily basis. Such useless calls are regulated. That you can't do that.

[0008] That is, the incoming call to the conventional telephone,
When the terminal having the called subscriber's telephone number (DN) is in a state where it can receive a call (hereinafter referred to as "Idle state"), the call is received, and a state other than the Idle state such as busy (hereinafter referred to as "Busy state") Call)
Is a method of rejecting incoming calls. However, in general, there are a plurality of users for one subscriber telephone number, such as an office as shown in FIG. 2 or a home telephone as shown in FIG. Irrespective of the terminal state (Idle / Busy above), the state of being able to talk according to the time zone (such as when you can talk on the phone while at the terminal side),
Or, the call cannot be made (for example, when you are temporarily out of the office such as on a business trip, cannot answer a call during a meeting, or have not yet returned home). Each state is called "answ
Called "erable / unanswerable state".

In the conventional telephone receiving system, the receiving terminal is Idle
If the user enters the unanswerable state even after the state is reached, this call will eventually become a useless call as follows. As a result, from the point of view of the calling subscriber, they are charged even though they cannot actually talk to the person they want to talk to. Also, from the viewpoint of the receiving subscriber, other answerable users will have time to use the terminal, and those who answer the phone on behalf of the unanswerable user will be interrupted from their current work, Takes time. Further, from the point of view of the communication network, the time during which the connection equipment of the exchange can be used is taken for other calls.

Secondly, in the conventional incoming call control method based on TRDI such as a personal identification number, there are two patterns of connection / disconnection to the receiving terminal as operations after TRDI determination, that is, normal incoming / Busy
Only Tone connection, no flexibility in response operation. For example, by TRDI, (a) incoming call, (b) BusyTone connection, (c) announcement announcement connection, or (d) response to another telephone number can be considered, but in the conventional method, Responses other than (a) and (b) cannot be made.

In connection with this, Japanese Patent Application Laid-Open No. 4-27258 discloses a calling-side control incoming connection system, but the password in this system is service-compatible only, Is entered under

An object of the present invention is to provide a number of "calls permitted to non-callable terminal users" which cannot be ignored even on a daily basis.
It is an object of the present invention to provide a terminating connection control device and a terminating connection method that can restrict useless calls.

It is another object of the present invention to provide a more flexible incoming call connection control device and incoming call connection control method suitable for each user.

[0014]

A first incoming call connection control device according to the present invention includes a TUPN-related information table for registering a user's telephone call permission / inhibition state for each user's personal number corresponding to a subscriber's telephone number. When there is an incoming call to the subscriber's telephone number, the personal number of the user sent from the calling subscriber matches the personal number of the registered user, and the TUPN
According to the contents of the related information table, the incoming call is connected only when the user is currently in a call-enabled state.

Further, the second incoming call connection control device of the present invention provides, for each user's personal number corresponding to the called subscriber's telephone number, a response at the time of an incoming call to a user in a call availability state and a user in a call unavailable state. A TUPN-related information table for registering an operation is provided, and when there is an incoming call to the subscriber's telephone number, the personal number of the user sent from the calling subscriber and the registered user's individual Number matches, but said
According to the contents of the TUPN related information table, when the user is currently in a call unavailable state, the registered response operation is performed.

Further, the incoming call connection control method of the present invention includes, for each personal number of the user corresponding to the incoming subscriber's telephone number, the user's call enable / disable state and the response operation to the user in the call disable state when receiving a call. A procedure for registering in the table, a procedure for inputting an announcement of the personal number of the called party to the calling subscriber when a call is received at the subscriber's telephone number, and a procedure for transmitting the called party's personal number from the calling subscriber. Receiving, the procedure for searching whether the personal number is registered in the table,
If the personal number is registered, the procedure for connecting the incoming call and the personal number are registered if the user is currently in a callable state according to the contents of the table,
A step of performing the registered response operation when the user is currently in a call-disabled state according to the contents of the table.

The present invention provides three concepts, namely, a subscriber to a called subscriber's telephone number (DN).
TUPN (Terminal User)
Private Number), the user's call enable / disable state (at the current terminal) for each TUPN (TUPN state), and the TUPN in the call disable state
A response operation (UASA: unanswerable state action) is introduced, and the TUPN related information is registered in the communication network side (exchange center or the like) in advance.

Then, when there is an incoming call to the subscriber terminal, it is compared with the TUPN as the party to talk to which is sent from the calling subscriber, and by referring to the TUPN state of the corresponding TUPN, the connection to the called terminal is determined. In addition, if the connection is not to be established, a response operation is performed by the UASA of the corresponding TUPN, and as a result, it is possible to regulate incoming calls to users who can not talk at present, which can not be regulated by the conventional method, Provided is an incoming call control method that enables a more flexible response operation (an operation other than connection / disconnection to a called terminal can be specified for each TUPN) than the incoming call control method using a password.

More specifically, as shown in FIG. 1, the switching center 10 includes a communication path system device (switch) 20, a control device 30,
The TUPN information of the called subscriber telephone number (xx-yyyy) is registered as an updatable related information table 50 in the memory 40.

First, a personal TUPN is assigned to each user of the called subscriber's telephone number xx-yyyy, and the user wants to activate the TUPN state and activate a response when the user cannot talk and the call cannot be made (this subscriber The identification number (SIN:
Service Identification Number) is registered or updated in the table 50.

Thereafter, the switching center 10 receives, for example, the calling subscriber S1.
When there is an incoming call from this to this subscriber (xx-yyyy is dial), the controller 30 requests the user TUPN of xx-yyyy to the calling subscriber S1 and uses the transmitted TUPN (02) as a key. The TUPN related table 50 is searched for a record of the corresponding TUPN, and the TUPN is searched.
Connect to the receiving terminal by state.

On the other hand, in the case of the calling subscriber S2,
Since the TUPN state for TUPN (01) is "0", the control device 30 does not connect to the terminating terminal, and furthermore, SIN (12) in the third field
, And activates the service such as the absence announcement connection. In this way, it is possible to restrict incoming calls to users who cannot make calls at the current terminal and to control incoming calls for flexible response operations.

[0023]

Next, embodiments of the present invention will be described with reference to the drawings.

First, referring to FIG. 2, this figure shows an office telephone environment in which one subscriber terminal telephone number xx-yyyy is used by five persons of manager A, secretary B, supervisor C, staff D and staff E. Is shown. Manager A is waiting for customers and cannot talk, secretary B and staff D can talk, supervisor C cannot test and talk, staff E cannot travel and talk. Each member has a personal number TU
PN is attached, and the call availability status (TUPN
state) and correspondence when calls cannot be made (UASA).

Referring now to FIG. 1, one embodiment of the incoming call control device of the present invention is an exchange 10 including a communication path device (switch) 20, a control device 30, and a memory 40. The outline of each of these elements is as follows. The memory 40
This is a device in which the data of each subscriber including the destination subscriber telephone number xx-yyyy is stored. In the device, a user personal number (TUPN) related information table 50 for the subscriber, which is unique to the present invention, is registered. Have been.

The TUPN related information table 50 includes records of related information for each TUPN.
It consists of three information elements (fields): PN, TUPN state and UASA. The TUPN value “00” is dedicated to an abnormal case such as no TUPN input from the calling subscriber. TUPN
The value “1” of the state indicates that the user can make a call, and the value “0” indicates that the terminal is currently unavailable due to temporary absence.

UASA is a service identification number of a terminating system activated as a response when TUPN state = "0". Value “00”
Is normally dedicated for disconnection, a value of "11" means call forwarding, a value of "12" means connection to an out of office announcement, and a value of "13" means connection to a voice mail device for recording a calling subscriber message. In addition, although three types of terminating services are described here, the present invention is not limited to this, and other terminating services can be similarly added.

TUPN reflecting the telephone environment of the office shown in FIG.
The contents of the related information table 50 are as shown in FIG.

The control device 30 controls the communication path system device 20 to perform the line switching operation of the switching center 10, and further performs the following processing on the TUPN related information table 50. That is,
The above-mentioned TUPN, TUPN state
And UASA, and update the TUPN record of the corresponding user. Also, when there is an incoming call to subscriber telephone number xx-yyyy,
It requests the TUPN from the calling subscriber, searches for the corresponding TUPN record using the sent TUPN as a key, and determines the connection to the called terminal according to the TUPN state value. When not connecting, SI
Invoke the response service based on the N value.

Next, the overall operation of this embodiment will be described with reference to the flow charts of FIGS. 1, 2 and 3.

First, as shown in FIGS. 1 and 2, a personal TUPN is assigned to each user of the called subscriber telephone number xx-yyyy, and the user operates his / her own TUPN, TUPN st by operating a terminal as follows.
Request the exchange 10 to register ate, SIN (only when TUPN state = 0). The input for this registration is, for example, TUPN = “01”
* 22 * 01 * 0 * for the user of, that is, Manager A
12 #. * 22 * is the identification code of TUPN registration operation, 01,0,12
Are TUPN, TUPN state, and SIN, respectively. Also, TUPN =
* 22 * 0 for the user of “02”, ie secretary B
2 * 1 #. The control device 30 receives the request and registers and updates the record of the corresponding TUPN (01, 02) in the TUPN related information table 50. Note that the information of the abnormal case-specific TUPN = “00” can be similarly set.

Thereafter, when there is an incoming call to this subscriber, for example, when the calling subscriber S1 dials the subscriber's telephone number xx-yyyy, as shown in FIG.
Connect the TUPN input request announcement (step 31),
Wait for an input within a fixed time (step 32). When the TUPN is sent from the calling subscriber (step 32), it is received.
(Step 33), the TUPN related information table 50 is searched for a record of the corresponding TUPN (Step 34), and if it is registered, the TUPN state is referred to (Step 35). Then, as in the case of the user 02, when the TUPN state = "1", the normal incoming call processing, that is, the connection to the called terminal is established (step
36).

On the other hand, like user 01, TUPN state =
If it is "0", the SIN is further read (step 37), and the corresponding terminating service is started (step 38). For example,
For user 01, the absence announcement connection is made, and for user 03, the call is transferred to the telephone number in the test room.

In step 32, if there is no TUPN input from the calling subscriber even after waiting for a predetermined time, or step 34
In the case where there is no record of the input TUPN in the TUPN related information table 50 (unregistered user), the value of the input TUPN is set to the abnormal case exclusive value “00” (step 39), and the TUPN = According to the “00” record value, connection determination processing for the called terminal is performed.

Next, another embodiment of the present invention will be described with reference to FIGS. This embodiment corresponds to a case where the receiving subscriber has a plurality of terminals for one subscriber telephone number, such as ISDN, and identification information (subaddress) exists for each terminal. By simply specifying the user's TUPN, the calling subscriber can automatically select the terminal of the user who wants to talk at any time and receive a call.

Referring to FIG. 4, the present embodiment is directed to an ISDN subscriber having a plurality of terminals where the called subscriber telephone number xx-yyyy is a plurality of terminals, and FIG. Shows telephone environment, living room on the first floor, father, son and daughter, and mother in kitchen. Therefore,
The stste of the user TUPN is all “1”, and UASA does not need to consider it. In this case, the TUPN related information table 60 has a fourth field (61) in the record of each TUPN.
Is different from the TUPN related information table 50 in FIG.

This field 61 contains "call destination terminal subaddress
(T_SUB: Terminating Subaddress) "for each user (TU
The subaddress value of the terminal to be connected when an incoming call arrives at PN) is registered. Also, TUPN state =
When it is “1”, registration for the called terminal subaddress T_SUB, and readout and setting processing are added.

Next, the operation of this embodiment will be described.

When each user registers his / her TUPN-related information (such as TUPN state) by operating the terminal, the user also requests the exchange 10 to register the subaddress information of the nearest terminal at the present time.
For example, assume that the user 04 inputs * 22 * 04 * 1 * 1001 # from the terminal. * 22 * is a TUPN registration identification code, and 04,1,1001 are TUPN, TUPNstate, and T_SUB, respectively. The control device 30 receives the input and receives the corresponding record in the TUPN-related information table 60.
(TUPN04) is updated.

When there is an incoming call to the subscriber, in this example, when the calling subscriber S1 dials the subscriber telephone number xx-yyyy,
The control device 30 performs the same processing as in steps 31 to 35 in FIG. 3 (TUPN input request → TUPN reception → TUPN related information table 6).
(From 0, read the corresponding TUPN record → TUPN state judgment)
Perform

However, when TUPN state = “1”, the control device 30 performs the following processing unique to the present embodiment between step 35 and step 36. That is, the receiving terminal subad of the SETUP (call setting) message to be transmitted to the receiving subscriber from now on.
dress is set to the T_SUB value of the corresponding TUPN (1001 in this example), and the process returns to the normal incoming call process (step 36 in FIG. 3). As a result, this call becomes an incoming call to the specific terminal (close to the TUPN = 04 user) (1001). When TUPN state = “0”, the same processing as in step 37 and subsequent steps in FIG. 3 is performed.

FIG. 4 shows the telephone environment in the home in the evening. At midnight, the whole family moves to the bedroom on the second floor, and the telephone environment shown in FIG. 5 will be obtained.
As described above, when the user changes his / her terminal (from the living room terminal 1001 to the terminal 2003 in the bedroom 3) as in the case of the user of TUPN = “04” depending on the time zone, the user can use the terminal in the same manner as described above. Just press * 22 * 04 * 1 * 2003 # to suba again
ddress registration request, TUPN = “04” record T_SUB
The value is updated to the new terminal's subaddress (2003).

Thereafter, when there is an incoming call to itself, the control device 30 sets the receiving terminal subaddress of the SETUP message to "2".
003 ”, and eventually this call automatically becomes an incoming call to your current user terminal“ 2003 ”.

According to the present embodiment, the following two new effects can be obtained when the called subscriber has a plurality of terminals such as ISDN and has identification information of the terminals.

[0045] The first is that the caller side is the destination user's personal number T
Just specify the UPN and the other party's terminal
This means that you can always select the user terminal you want to talk to and receive a call without having to know the s value.

The second problem is that, even if the receiving user changes the terminal used, there is no need to perform the following troublesome work.
By simply re-registering the T_SUB of the own TUPN, a call to itself can be automatically selected and received by a new user terminal. If the present embodiment is not followed, when the terminal is changed, the conventional work necessary for receiving a call to the new terminal is performed. That is, if (1) the subterminal of the new terminal has a different value, the value is notified to all calling subscribers, or (2) the subad of the new terminal
If you want to keep the previous value of dress, use the old terminal's subaddres
You need to delete s and register the subaddress on the new terminal. However, when there are a plurality of users such as “1001” in FIG. 4, the influence is exerted on other users.

[0047]

A first effect of the present invention is that it is possible to regulate a useless number of "calls permitted to terminal users who cannot make calls" which cannot be ignored even on a daily basis. It is.

The reason is that, for each user of the incoming telephone number, a personal number (TUPN), a call enable / disable state (TUPN state), and an operation when the call cannot be made (SIN) are registered in the communication network. This is because when there is an incoming call to the user, the connection to the called number terminal and the operation when not connected can be determined based on the information.

The second effect is that a response operation suitable for each user, such as guidance announcement connection or transfer, is set in contrast to the conventional method in which connection / disconnection to a receiving terminal can only be restricted by a password. That is, it is possible to provide a flexible incoming call control system that makes it possible.

The reason is that a terminating service as a response operation other than connection / disconnection can be separately activated for TUPN.
