Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a service control device.

In recent years, UPT (Universal Personal Telecommunica) has become a new communication service system such as CCITT.
tion) Services are being considered. The UPT service sets a personal number for each subscriber and uses the personal number to provide various services in the public network. It is desired to realize a control device for bringing this UPT service to a practical level.

[0003]

2. Description of the Related Art The UPT service is currently under consideration in CCITT. However, in addition to a telephone number given to a device such as a telephone, a call is made using a personal number registered in advance for an individual. It is intended to provide the communication service of. Specifically, it is a conventional telephone number (DN: DirectoryN) for each subscriber.
umber) different personal number (PTN: Personal Te
It is possible to access a specific individual simply by giving a lecommunication number and dialing the other party's personal number (PTN). Further, if the caller notifies the network of his / her own personal number to make a call, a service such as charging the individual of the caller becomes possible.

It is planned that such a service will be provided by AIN (advanced IN), which is an improved version of IN (intelligent network) which is a new network system.

[0005]

In the service provided as the UPT service, the number (telephone number) of the terminal such as the telephone set of the called party (callee) corresponding to the personal number (PTN) is registered in advance. When there is a call from another subscriber dialing that personal number as the other party, there is a service in the network where the telephone number is extracted from the individual number and the call is made by connecting to that telephone.

However, according to this service control method, when an individual accesses (incoming, etc.) an individual while moving from one place to another, or when the individual is not in a pre-registered whereabouts, the When there is an access, there is a problem that a call cannot be made because a response is not returned even if a telephone registered in advance for the individual is called from the network because there is no other party.

The present invention is a service control device capable of realizing various services such as retrieval of a transfer destination, recording of call history, and calling when a user is absent when receiving a personal number in practical use of UPT service. The purpose is to provide.

[0008]

According to the present invention, in the UPT service, the user can call the other party by dialing either the PTN or the telephone number, and notify the moving user of the absence of the incoming call or the incoming call when the user is absent. The service for users is enhanced, for example, by recording a call so that the user can know the contents later.

[0011]

In order for the subscriber to receive the UPT service, a PTN (Personal Telecommunication Number) is assigned to the individual, and the telephone number and related data corresponding to the PTN are registered in the table section 7 of the service control device 4. Need to be

(1) Calling the other party When calling from one subscriber's telephone set 1 to another subscriber's telephone set 2, dialing a special number requesting a call by the UPT service, the service control unit 4 is sent to the service control unit 4 via the exchange control unit 3. Be notified. When the service identification unit 5 identifies the special number and identifies the type of service to be requested, the corresponding service control unit 6 (UPT connection service control unit 6a) is driven. When a PTN is sent from a subscriber of the telephone 1 (hereinafter referred to as subscriber 1), it is received by the UPT connection service control means 6a via the exchange control device 3, and the PTN is received.
Check using the data in the management table 7a,
When qualified, the subscriber 1 is instructed to enter information for designating the other party.

The subscriber 1 who receives this from the exchange control unit 3
When the PTN or telephone number representing the other party is sent, the UPT connection service control means 6a identifies this, and when receiving the PTN, the PTN management table 7a is used to convert the PTN into a telephone number. When receiving the telephone number of the other party and P
The telephone number converted from the TN is sent to the exchange control device 3 together with a connection instruction. The exchange control device 3 controls the connection between the subscriber of the telephone 2 having the partner telephone number (hereinafter referred to as subscriber 2) and the subscriber 1.

(2) When the registered subscriber 1 dials the registered special number when changing or moving, the service controlling unit 4 is notified via the exchange control unit 3, and the special number is identified by the service identifying unit 5 to register. The change / movement service control means 6b is activated. After this, when the change / movement service control means 6b notifies the subscriber 1 of the input request via the exchange control unit, the PTN of the subscriber 1 and the telephone number (transfer destination) of the changed or moved destination, the change Alternatively, when the time information (date, time) or the like for which the movement is valid (for example, arrival at the destination) is input, the PTN management table 7a
Is registered in the PTN area of the relevant subscriber. When an incoming call using the PTN from the telephone 2 of another subscriber occurs to the subscriber 1 within this moving time, the service control device indicates that it is within the moving time registered in the PTN management table 7a. In step 4, the switching controller 3 is instructed to notify the subscriber 2 that he is moving and to call back later.

Further, the telephone number and time of the call received during the movement are stored in the movement call history table 7b. After the move, the subscriber 1 dials the search special number to check the call received to him during the move and inputs his PTN, and the change / movement service control means 6b of the service control device 4
The calling telephone number and the time of each call stored in the mobile call history table 7b are searched for and sequentially sent to the subscriber 1.

(3) Sequential search dialing service The subscriber of the telephone 2 inputs the PTN of the person (the subscriber of the telephone 1) he / she wants to call by the normal UPT service,
If the other party does not respond within a certain time when the other party is called by the connection with the other party by the operations of the exchange control apparatus 3 and the service control apparatus 4, the sequential search dialing service control means 6c is activated. The sequential search dialing table 7c used in this service stores a plurality of telephone numbers registered in advance by the subscriber of the PTN as transfer destinations.

The sequential search dialing service control unit 6c in the service control unit 4 retrieves the telephone number registered at the head of the sequential search dialing table 7c,
It is given to the exchange control device 3 together with the connection instruction. The exchange control device 3 thereby connects and calls the telephone.
If a response is not returned from this telephone, the telephone numbers in the next order in the retrieval dialing table 7c are sequentially searched and the same control is performed until a telephone for which a response is returned is found.

(4) Personal telephone directory service When the subscriber of the telephone set 1 inputs his PTN and makes a call by dialing the other party's PTN or telephone number by the UPT service, the telephone directory service control of the service control device 4 is performed. The means 6d instructs the switching control device 3 to make a corresponding connection, and records each number data in the telephone directory table 7d provided for each PTN of the caller. That is, the PTN or telephone number of the other party transmitted by the subscriber corresponding to the PTN of each sender and the name of the other party are recorded in the telephone directory table 7d functioning as a telephone directory. In the telephone directory table 7d, the record is updated in a form in which the number of times is added at the time of calling (accessing) to the other party recorded previously.

When the subscriber wants to refer to his / her own telephone directory, he / she dials the telephone directory special number and inputs his / her PTN. As a result, the telephone directory service control means 6d operates to take out the contents of the telephone directory table 7d of its own. In this case, if the subscriber's telephone is a digital telephone having a display function, each access (call) recorded as a digital signal from the service control device 4 in the telephone directory table 7d.
Are sent one by one and displayed on the subscriber's telephone 1. When it is not a digital telephone, it is notified by voice.

The subscriber who receives this, the other party who wants to call (determined by name, PTN or telephone number)
When a signal is sent from the telephone 1 when is found, the service control device 4 detects this. The service control device 4 gives a connection instruction to the exchange control device 3 using the partner PTN or telephone number which is the access data at that time. In this way, the telephone set 1 of the subscriber is connected to the designated party.

[0021]

FIG. 2 is a block diagram of a system in which the present invention is implemented, FIG. 3 is a sequence (1) of transmission / basic connection processing of the embodiment, and FIG. 4 is a sequence of transmission / basic connection processing of the embodiment ( (2), FIG. 5 is an explanatory diagram of the table stored in the database, and FIG. 6 is an explanatory diagram of the telephone directory table.

In FIG. 2, reference numeral 20 designates telephones of a large number of subscribers, 21 designates an exchange (corresponding to the exchange control device 3 in FIG. 1).
And SSP in IN (Inteligent Network)
(Service Switching Point). 26 is a communication path, 27 is connected to the exchange 20 via the communication path 26,
A computer (corresponding to the service control device 4 in FIG. 1) that controls the UPT service. This computer 27 uses the SCP (Service Control Point
t). The communication path 26 connecting the exchange 21 and the computer 27 is an X. 25 protocols (packets),
F via Ethernet or optical cable
It is composed of a high-speed line and a high-speed bus interface according to the DDI (Fiber Distributed Digital Interface) protocol, and the processing is realized by placing the UPT application data on the lower layer of these.

The exchange 21 detects a switching unit (indicated by SW) 22, a switching control requested by a subscriber, and a UPT service request, and transmits information to the computer or is transmitted from the computer. A processor (indicated by CC) 23 that executes processing such as executing an instruction,
A memory (displayed by MM) 24 for storing programs and various data for controlling exchange functions and UPT service special number detection, a signal processor 25 for executing an interface with the switching unit 22 and an interface with the computer 27 are provided. .

The computer 27 is a signal processor 28 for controlling interworking with the exchange 21 and protocol, a processor (CC) 29 for performing processing for executing UPT service, and a memory for storing a service control program for UPT. (MM) 30 and a disk device 31 that holds a large-capacity database related to the UPT service. As the disk device 31, a RAM disk device capable of high-speed access is suitable.

3 and 4 show the sequence of the transmission / basic connection processing by the UPT service realized in the system as described above. To explain this, first, referring to FIG.
In step 3, the calling subscriber who receives the UPT service sends a special number indicating the UPT calling from the telephone set 20 to the exchange 21 (a in FIG. 3). When the exchange 21 receives this, UPT
It is detected that it is a special number (the same b). Then, the exchange 2
1 notifies the computer 27 of the UPT transmission special number (the same c). When the computer 27 receives this,
The special number is checked (at the same d), and when it is detected that it is the determined UPT transmission special number, an operation for instructing the transmission of a digit collection announcement is performed (at the same e). As a result, the signal “Collect Digites” instructing the exchange 21 to send out an announcement instructing to collect the personal number.
(ANA) ”(simply“ Instruction (ANA) ”is displayed in the figure) (same f).

Upon receipt of this, the exchange 21 makes an announcement "Insert your PSI, if there is no PSI, please insert #" from the built-in announcement device (not shown). To (the same g,
h). In addition, this "PSI" is a personal subscriber identification number (Personal Subscriber Identification),
It is composed of a PTN (Personal Telecommunication Number) and a password added thereafter.

When the subscriber of the telephone set 20 which receives this input request inputs the PSI (same i), the PSI is set by the exchange 21.
The digits of each number (PTN + password) are collected (at j), and the computer 27 is notified of PSI as a response signal (at k). When the computer 27 receives the PSI, the computer 27 accesses the PTN management table (same as 1) and matches the password registered in advance in the area corresponding to the PTN of the subscriber in the PTN management table (same m). ). If a match is found by this matching, the charge for the call to be made from the other party will be charged to the individual having the PTN on the calling side (not to the telephone). As a result, for example, it is possible to make not only domestic calls but also international calls from public telephones without using money or prepaid cards.

If the subscriber of the telephone 20 inputs "#" without inputting PSI, the above PSI check processing is skipped.

The structures of various tables used in the UPT service of the present invention are shown in FIGS. These tables are stored in the disk device 31 provided in the computer 27 of FIG. An example of the PTN management table is shown in FIG. , The area addressed by the PTN in the table stores the data related to the PTN, and includes "name" (personal name, company name, etc.), "password", and "transfer destination DN". The "movement timer" following this is used for other services described later.

Returning to the explanation of FIG. 3, the P sent from the subscriber is sent.
When the SI and the password of the PTN registered in the PTN management table can be matched or the PSI check is skipped, the computer 27 instructs the exchange 21 to send a digit collection announcement (same n,
o).

After that, the procedure goes to the sequence shown in FIG. 4, and the exchange 21 which has received the above-mentioned instruction gives the telephone 2 an announcement saying "Please insert the other party's DN or * + the other party's PTN".
It is sent to 0 subscribers (p, q in FIG. 4). Phone 2
The 0 subscriber inputs the PTN with the DN (telephone number) or "*" at the beginning (r in FIG. 4). The input number is subjected to PTN collection processing by the exchange 21, and the collected number is sent as a response signal to the computer 27 (s, s,
t). When the computer 27 receives this, when the other party's PTN is received, A.A. PT as shown in
N management table is accessed (same as u), and "transfer destination DN"
To obtain the DN (telephone number) of the other party having this PTN (v). When the subscriber of the telephone 20 inputs the partner DN, the computer does not execute the process of converting the partner PTN into the DN.

When the computer 27 obtains the DN of the other party,
DN is given to the exchange 21 and a connection instruction (Connect) is given (same w). The exchange 21 which received this performs a normal connection process (same x). Specifically, the signal processor 2 of FIG.
5, the information of the telephone set 20 of the calling subscriber and the partner DN received from the computer are used to connect the two, and the switching unit 22 is switched by the signal processor 25 to form a speech path.

In the above sequence, the calling subscriber receives only the service that charges the PTN of his / her own, and P
If there is no need to call the other party using TN, PSI
The PSI may be input in response to the input instruction (h in FIG. 3), and the other party's DN may be input in response to the subsequent PTN input instruction (q in FIG. 4) from the exchange 21.

Next, the processing sequence of the moving announcement service will be described with reference to FIGS. 7 to 9.

In the moving announcement service, when the subscriber changes the telephone number or moves to another place, the change destination or the move destination is registered in advance, and at the same time, the timer (day / hour) in which the change becomes effective. ) Is also registered, it is a service that announces that the subscriber is moving when an incoming call from another subscriber occurs while the subscriber is moving.

FIG. 7 shows the registration processing sequence of the moving announcement service.

In the sequence of FIG. 7, the UPT originating subscriber who wants to receive the moving announcement service first makes a U request.
When the PT registration special number is sent to the exchange, the same operation as the sequence shown in FIG. 3 is performed (a in FIG. 7). That is, when the UPT registration special number is received, the registration process is started in the computer, and the PSI is input from the subscriber to check whether the subscriber is qualified to receive the UPT service. After this, the computer announces to the exchange (instruction to enter the destination DN (phone number))
Is issued (b in FIG. 7). As a result, the exchange sends the corresponding announcement to the subscriber (at c and d). When the subscriber inputs the DN, the exchange collects the number and notifies the computer as a response (e to g).

The computer uses the PTN management table (see FIG. 5).
A. Access (see h), and the subscriber's PTN
Register the DN received as the data of the transfer destination DN in the area corresponding to (included in the PSI received in FIG. 7A) (the DN corresponding to the previous PTN).
Is changed) (same i).

When the change is completed, the computer instructs the exchange to send an announcement for instructing the time input (at j). From the exchange, for example, an announcement of a time input instruction is sent to the subscriber, such as "how many minutes do you want to transfer the data?" (At the same k and l). If you enter the time (including date and time) required to reach the destination from the subscriber,
The exchange receives numbers (same m and n). In the example of FIG. 7, only the time is input, and “30 minutes” is displayed, which is “30 minutes”.
# Is entered. In this case, if you want to start the transfer immediately, for example, simply enter "#".

When the exchange notifies the computer of the information indicating this time (at the same o), the computer accesses the PTN management table and registers the notified time as a movement timer (see A. in FIG. 5) (at the same p). , Q). The computer starts the process of decrementing the value of the movement timer at regular intervals (operation of -1) (at r). In addition,
When this decrement operation is started, a flag (not shown) indicating the state of the movement timer is set to the on state, and when the timer exceeds the set value, the flag is set to the off state. Next, when a notification of registration completion is notified to the exchange (s, t) (same), the exchange sends a notification of completion notification to the subscriber (same u, v). This announcement has the content, for example, "UPT number change completed."

In this way, after the registration by the subscriber who receives the moving announcement service is executed, the moving access processing sequence shown in FIG. 8 is executed.

That is, when the calling subscriber makes a call to a subscriber who has the PTN registered as described above (this is called PTN subscriber A) (a in FIG. 8), the U
Identifies the PT service and notifies the computer with the other party's PTN and caller number (the same b,
c). In addition, the caller number is a conventional exchange (for example, IS
It can be known because it is included in the call setting information detected or sent from the calling side by DN).

Upon receipt of this, the computer accesses the PTN management table (A in FIG. 5) and checks whether the movement timer is on (flag) (d, e in FIG. 8). If it is ON, it is known that the subscriber is currently moving, and the transfer destination DN in the PTN management table is taken out for use in the subsequent processing (same f). Then, the caller number and time are registered in the moving call history table provided for this moving announcement process (the same g).

This mobile call history table is shown in FIG. Shown in. This table is a table for sequentially registering information of all calls received while the subscriber who receives the moving announcement service is moving. "D" of the calling subscriber of the call received while the subscriber is moving to the area corresponding to the PTN of the subscriber who receives the service of this table
“N and date and time” or “[* + PTN] + date and time” are sequentially registered each time a call occurs.

Returning to the explanation of FIG. 8, when the registration in the table is completed, the computer issues an announcement transmission instruction to the exchange. At this time, the transfer destination DN acquired in the above process (f in FIG. 8) is added and sent (same h, i). The exchange responds to this, for example, "I am currently using DN (○○ ・ ○
Moving to No.), I will call back as soon as it arrives. "
k).

Next, FIG. 9 shows a processing sequence of history access search. This operation is to know the history of calls received by the subscriber who receives the moving announcement service to the destination after the subscriber receives the moving announcement service and while the subscriber is moving to the subscriber (whose destination is the own PTN). This is possible processing.

When a calling subscriber makes a call by using a special number for history access of the UPT service (a in FIG. 9), the U
PT special number is detected and notified to the computer (Same as b,
c).

When the computer checks the special number and identifies that it is an access for call history retrieval (Same as d), it issues a digit collection announcement transmission instruction to the exchange (same as e and f). In order to confirm the identity of the calling subscriber by this, the exchange uses the PTN management table in the computer for PSI input announcement and PSI input in the same manner as in the above processing sequences (see FIG. 3).
SI check is performed (the same g to l). When the confirmation is obtained by the check, the mobile call history table (B in FIG. 5) is accessed, and the number (DN or PTN) registered in the call history stored in the area of this subscriber (PTN) and the date and time information are accessed. Take out (m, n in FIG. 9). The extracted contents are sent from the computer to the exchange together with an announcement instruction (same o, p).

The exchange announces the number and the date and time according to the instruction (the same q, r). The announcement was, for example, "There was a call from the following user, please call back.

January 1, 3:43 PTN 7771111 January 1, 3:50 DN 71222222 January 1, 3:55 PTN 7773333 ”. The announcement is repeated until the calling subscriber disconnects. When the calling subscriber disconnects (same),
When the exchange detects this and notifies the computer, the computer clears (erases) the contents registered in the PTN of the mobile call history table (t, u).

Next, the processing sequence of sequential search dialing will be described with reference to FIG. This sequential search dialing process is performed by the UPT service when a call is made by designating the other party's PTN, and when the other party does not respond due to the absence of the other party, the other party is selected from the destinations registered in advance by the other party's PTN. Realize a service that searches for the location (phone) and automatically dials. An example of the case where the other party is absent includes a case where a subscriber who is planning to move forgets to register the destination DN by registering the moving announcement service (see FIG. 7) and moves.

In FIG. 10, when the calling subscriber makes a call by the PTN and is notified to the computer through the exchange, the DN corresponding to the partner PTN is detected from the PTN management table (A in FIG. 5), and is sent to the exchange. On the other hand, the connection instruction is given with the DN (a to d in FIG. 10). The exchange is D
When a call is made by connecting to the other party by N, if no response is detected even after a certain period of time has passed, no response is reported to the computer (e to h). Upon receiving this, the computer sequentially accesses the search dialing table (i).

An example of this sequential search dialing table is shown in FIG. Shown in. In this table, a plurality of DNs for sequentially receiving a search dialing service are sequentially registered in advance by a subscriber according to a registration processing sequence (FIG. 11) which will be described later.
N is stored in order.

Returning to the explanation of FIG. 10, the computer checks the number of registered DNs stored in the area corresponding to the partner PTN of this table (j in FIG. 10) and extracts the first DN (same k). When the announcement instruction of the extracted DN is given to the exchange, the exchange sends the announcement to the calling subscriber (the same 1 to n). The content of the announcement at this time is
For example, "No response, search for user. Call DN, 7122234 of next access destination". If the calling subscriber is an ISDN-compatible telephone, the number may be displayed when the DN of the access destination is notified in the form of a digital signal without being sent by voice from the exchange. Further, the name (obtained by referring to the PTN management table by the PTN) can be displayed together with the access destination DN.

On the other hand, when the computer gives a connection instruction by the DN to the exchange (o, p), the exchange makes a connection for the DN and calls (q, r). When the other party responds, the exchange establishes a call path with the calling subscriber and the call is made. Although not shown in FIG. 10 after the call is finished, when the calling subscriber hooks, the switch detects this and notifies the computer.

The computer sequentially extracts the DN registered next to the search dialing table by the notification,
The same operation sequence as the above k to r is repeated.
This operation is continued until the request (hooking) from the calling subscriber is stopped or the dialing for all the DNs registered for the PTN in the sequentially searched dialing table (C in FIG. 5) is completed.

Next, the registration processing sequence in the above sequential search dialing table will be described with reference to FIG. This processing sequence is executed when the calling subscriber performs "registration", "modification" and "deletion" of the DN in his / her sequential search dialing table (C in FIG. 5). Shows an example of performing "registration".

First, the calling subscriber sequentially dials the registered special numbers in the search dialing table, and the PSI check sequence similar to that shown in FIGS. 3 and 7a is input from the computer, the exchange, and the subscriber. (A in FIG. 11). When the confirmation is obtained by the check, an announcement is sent from the exchange to instruct to input the DN (telephone number) to be registered from the exchange (b, c in FIG. 11). For example, send the content "Please enter the DN to be registered, the last is #". On the other hand, when the calling subscriber inputs "DN #" (same d), the exchange detects it and notifies the computer (same e). The computer sequentially accesses the search dialing table (same as f), and the calling subscriber (P
When it is confirmed that there is a vacancy in the TN area, the received DN is registered (at g and h).

When the registration is completed, an announcement is sent out, and when the completion exchange is sent out to the exchange, an announcement is sent from the exchange to the calling subscriber and the registration is completed (i to l).

When the contents of the sequential search dialing table are changed, the calling subscriber is made to input the DN to be changed, and when it is inputted, the contents are changed by making a new DN input next. When deleting, the code input from the calling subscriber may be different depending on whether the entire table is deleted or the specific DN is deleted.

Next, a processing flow for realizing the personal telephone directory service will be described with reference to FIGS. 12 to 15.

FIG. 12 is a processing flow of registration of a personal telephone directory. This process is a storage process that is executed when the subscriber who uses the service of the personal telephone directory makes a call and receives the information identified when the normal connection process is performed by the exchange. In this case, the received information from the exchange connection service processing is the PTN of the sender and the PTN or DN of the other party.

The structure of the storage table for storing the telephone directory data used for the personal telephone directory service is shown in the telephone directory table of FIG. The telephone directory data is stored in the area corresponding to the PTN of each subscriber, and comprises a storage table A and a storage table B. The accumulation table A is used for retrieval, the accumulation table B is used for accumulating new connection information, and both are switched at regular intervals (for example, January, half a year, and one year). Each of the storage tables A and B stores the number of the PTN or DN of the other party that this subscriber has transmitted, and the call number counter c that indicates the number of transmissions of each, and in the case of the storage table A used for retrieval, calls are stored. The number counters c are arranged in order from large to small.

In FIG. 12, a calling subscriber (PT
When the computer receives the information (S1 in FIG. 12) when the N) originates the connection process, the telephone table storage table (B) corresponding to the PTN is searched (S2). Search whether the other party's number (DN or PTN) is registered in it (S3 of the same), and if there is, the corresponding DN or P
The call number counter of the TN is updated (+1) (at step S5). If there is no partner number, the received number (DN or PT
N) and the name of the subscriber obtained using PTN are newly registered, and the call counter is updated (S4, S5).

FIG. 13 shows a processing flow for switching the faces of the storage tables A and B for storing the data of the personal telephone directory. That is, when the preset period is reached, the periodical process is activated (S1 in FIG. 13), and the A / B side switching pointer of the accumulation table is operated (S2). By this,
The accumulation table that has been the A side until then is designated as the B side, and the B side is designated as the A side. Next, the storage table that became the new B side (used for searching up to that point)
Are all cleared (at step S3), and the newly stored storage table (which has been used for storage up to that point) on side A is sorted in descending order of access frequency (displayed by the call counter) (at step S4).

FIGS. 14 and 15 show the processing flow (No. 1) and (No. 2) of the telephone directory search for making a call using the personal telephone directory.

When using this personal telephone directory, 2
Any one of the two search methods can be selected. One is "sequential search", which searches the telephone directory in order of frequency, and the other is "fuzzy number search" (hereinafter simply referred to as "fuzzy number search" in which you do not remember the entire number of the other party and enter only a part of it. This is called number search), and the flow will be described below.

When the calling subscriber enters the telephone book special number, the computer is activated via the exchange, and an announcement instruction is issued from the computer. From the announcement device of the exchange, "In case of sequential search," 1 # ", In the case of number search, input "2 #". "Is sent to the calling subscriber.

The subsequent processing is shown in FIGS. 14 and 15.
When starting, it is judged whether or not "1 #" is received from the calling subscriber (S1 in FIG. 14), and if "1 #" is received, the top data (DN and DN of the accumulation table A of the personal telephone directory is received. The name is taken out, sent out to the subscriber through the exchange (at step S2), and displayed on the telephone (not shown) of the calling subscriber.

An ISDN-compatible digital telephone is used as a telephone receiving the service of this personal telephone directory, and DN (and name) is displayed on the display. When the calling subscriber wants to call the person with the displayed telephone number and name by looking at the displayed contents, he / she operates feature key B (assigns one of the function keys of the digital telephone).
Hook when you want to see the next data in the phone book. If you want to retrieve and display the current personal telephone directory data in the reverse order, use feature key A
Operate (assign other function keys of digital telephone).

The following is an example of the case where the display contents at this time are PTN and name.

[7771111] JOHN BROWN Returning to FIG. 14, after transmitting the top DN (and name) of the above-mentioned A side, the feature key B from the calling subscriber is sent.
Is received (at step S3), and if it is received, an instruction (message) to receive (call) the DN being displayed is sent to the exchange (at step S4). Upon receiving this instruction, the exchange performs a connection process for transmitting the incoming call subscriber to the other party of the instructed DN and receiving the incoming call.

When the feature key B is not operated, the computer determines whether or not the feature key A has been received (at step S5), and if not, waits for hooking to be received (at step S6), and stores when hooking is received. Processing for extracting and displaying the next DN (and name) on the surface of table A is performed (at step S7). When the calling subscriber wants to reverse the display order, he / she operates the feature key A. In this case, the bottom (last) data on the A side is taken out and sent to the calling subscriber and displayed (S8 in the same). On the other hand, in S9, the reception of the feature key B is discriminated. The incoming call is performed. If the feature key B is not received, the processes of steps S10 to S12 and S9 are executed.

When "1 #" is not received at the beginning of FIG. 14, it is determined whether "2 #" is received (S13), and if it is not received, the process of rejecting the request is performed, and "2 #" is received.
When "#" is received, the number search process shown in FIG.

In FIG. 15, first, a number input instruction announcement transmission instruction is sent to the exchange (S14 in FIG. 15). After this, the number from the calling subscriber is received (at step S15). If the beginning of the received number is XXX (part of the number),
On the A side of the personal telephone directory (see Fig. 6), the beginning is "XX.
The number matching "X" is searched (at step S16). When a matching number is detected, information including the entire number (and name) is sent to the calling subscriber and displayed on the telephone (at step S17).

Next, it is judged whether or not a signal indicating hooking is received from the calling subscriber (at step S18), and if not received, another data having the next number ("XXX" on the A side is searched for). Then, when the hooking signal is received, an incoming message to the displayed number is sent to the exchange (S20), and the exchange sends the current calling subscriber to the designated party. And make an incoming connection.

According to the present invention, in the UPT service, it is possible to select whether the calling subscriber uses a personal number (PTN) or not. In the former case, the telephone number to be used is not charged and the personal number is not charged. Can be charged for. Also, since it is possible to specify whether the person to be connected is a personal number (PTN) or a telephone number, it is possible to increase flexibility.

When changing the telephone number corresponding to the PTN,
It is possible to specify the time it takes to move, and it is possible to notify the other party even if there is an incoming call within the specified time. Further, in this case, since the history of calls received during the traveling time (absence) is recorded and the recorded caller and number information can be retrieved later, contact with the other party can be ensured.

Further, when there is no response to the call by the PTN, the forwarding destinations registered in advance in the sequential search dialing table of the called party can be automatically recalled and received.

A telephone directory corresponding to a PTN user is automatically created when a number is accessed without the user having to bother to register it, and when using it, the contents of the telephone directory are sequentially transmitted to the user's telephone and displayed. Has realized a service in which when a signal specifying the desired partner is sent, the outgoing connection to that partner is automatically executed.
