Abstract

PURPOSE:To enable the telephone set for ISDN connecting to a bus wiring to implement incoming call processing automatically in matching with a schedule of the user. CONSTITUTION:A network connection section 5, a CPU 7, a decoding coding section 9, a RAM 11, a ROM 13, a schedule storage table storage section 15, a subaddress analysis section 17, an entry section 19, and a display section 21 are interconnected by an internal bus 23. A name and a schedule such as presence, transfer, absence corresponding to the name entered from the entry section 19 are stored in the schedule storage table section 15. When a call comes from the bus wiring 1 to the network connection section 5, the CPU 17 references the subaddress analysis section 17 to decode a subaddress in a call telegraphic message and to check to whom the call comes. The CPU 7 retrieves the schedule storage section 15 based on schedule corresponding to the called name and connects the network connection section 5 and the decoding coding section 9 when the called name is present to ensure the talking.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is directed to ISDN (Integr.
ated Services Digital Net
This work relates to the improvement of ISDN telephones as telephone terminals connected to the bus wiring of a transmission system (Integrated Service Digital Network).

0002

[Background Art] In an ISDN transmission system, ISDN networks are connected via digital transmission lines, and bus wiring extending from the ISDN network via a private branch exchange 1 is connected to a plurality of ISDN telephones, other video telephones, facsimiles, and personal computers. It is constructed by connecting terminal devices such as Among these terminal devices, when an ISDN telephone receives a call with its own number in a call message in a predetermined format sent from the caller's telephone at the start of a call, it emits an incoming ring tone to notify the user of the call, and the handset It is configured so that when you pick up the phone, it becomes ready for talking. Therefore, if the calling side sends a calling message with a number assigned to the ISDN telephone set, the caller can talk to the other party.

0003

[Problems to be Solved by the Invention] However, in conventional ISDN telephones, when a call is received, a ring tone is emitted to notify the user of the incoming call, and when the handset is picked up, the telephone becomes ready to talk. The person on the other end of the call can simply pick up the handset directly, but if the person picking up the handset does not know the schedule of the desired caller, the caller may be transferred several times, and then the caller is absent. There are many cases where they are not caught. Moreover, there is the trouble of having to say one's name and the name of the person to be called several times before finding out that the desired person is not available, and it is also time-consuming.

[0004] The present inventor discovered that in an ISDN telephone system, a subaddress, which is part of the terminal selection information in a call message sent at the time of a call, passes through the ISDN network and is transferred to the terminal's IP address.
The present invention was completed by focusing on the fact that the subaddress can be transmitted to the SDN telephone and can be used by the calling side by adding arbitrary information to the subaddress. The present invention was made to solve these conventional drawbacks, and it is possible to receive calls to the user only when the person using the telephone is present, and it is possible to receive calls to the user according to the user's schedule. The purpose of the present invention is to provide an ISDN telephone capable of automatically performing incoming calls and other processing.

[0005]

[Means for Solving the Problems] In order to solve such problems, the present invention provides instructions for storing and erasing arbitrary identification information regarding a user and at least an attendance schedule corresponding to this arbitrary identification information from the outside. a schedule storage section capable of storing and deleting the schedule in correspondence with arbitrary identification information, a transmitting/receiving section for at least transmitting and receiving calls via bus wiring, and a control section. The control unit controls the storage and deletion of the arbitrary identification information and schedule in the schedule storage unit based on the storage and deletion instructions from the input unit, and controls the storage and deletion of the arbitrary identification information and the schedule from the subaddress in the call message received at the transmission/reception unit. When extracting the arbitrary identification information, the transmitter/receiver section is controlled to search the schedule storage section and secure a call when there is an attendance schedule, and when there is a schedule other than attendance, processing is performed according to the schedule. The transmitter/receiver is controlled so as to perform the following.

[0006] In the present invention, the input section is formed so that a transfer schedule corresponding to the user can be instructed to be stored and deleted from the outside, and the transfer destination corresponding to the arbitrary identification information can be stored and deleted. forming the schedule storage unit in such a way that the arbitrary identification information is extracted, searching the schedule storage unit when extracting the arbitrary identification information, and controlling the transmitting/receiving unit to forward the incoming call to the transfer destination when a corresponding transfer destination is found. It is possible to configure a control unit. moreover,
The present invention provides a response message storage unit capable of storing and deleting a response message corresponding to the arbitrary identification information, and provides the input unit capable of storing and deleting an absence schedule corresponding to the user from the outside. The controller may be configured to control the transmitter/receiver to send a response message when the schedule storage unit is searched and a corresponding absence schedule is found when extracting the arbitrary identification information.

[0007]

[Operation] In the present invention equipped with such a means, when the input unit instructs to store the arbitrary identification information and the corresponding schedule of presence, transfer, or absence, the control unit stores the arbitrary identification information in the schedule storage unit. Stores identification information and schedules. In this state, when the transmitting/receiving unit receives an incoming call from the bus wiring, the control unit extracts arbitrary identification information from the subaddress in the received paging message, searches the schedule storage unit, and stores the attendance schedule corresponding to the arbitrary identification information. The transmitter/receiver is controlled to ensure a call at certain times, and when there is a schedule other than the presence of the person, the transmitter/receiver is controlled to perform processing according to the schedule.

[0008]Furthermore, in a configuration including the input section and schedule storage section capable of storing and erasing forwarding destinations, and a control section controlling the transmitting/receiving section so as to transfer incoming calls to the forwarding destination, when an incoming call is received, Incoming calls are automatically forwarded to the forwarding destination. Furthermore, in a configuration in which a response message storage section is formed in which the response message can be stored and deleted, and the above-mentioned transmitting/receiving section is controlled to send the response message,
If you are not present when the call arrives, a response message is automatically sent to the caller.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an ISDN telephone according to the present invention. In FIG. 1, a bus line 1 is a well-known line extending from an ISDN network (not shown), and an ISDN telephone 3 of the present invention is connected thereto. bus wiring 1
Although a plurality of ISDN telephones are connected to the terminal, since the configuration and operation are the same, only one is shown for the sake of convenience, and other illustrations and explanations are omitted. The ISDN telephone 3 includes a network connection section 5 connected to the bus wiring 1, a CPU 7, a decoding/encoding section 9, a RAM 11, a ROM 13, and a schedule storage section 1.
5, a subaddress analysis section 17, an input section 19, and a display section 21, which are connected via an internal bus 23.

[0010] The network connection unit 5 controls the incoming and outgoing calls to and from the bus wiring 1, and upon receiving the call, transmits the calling message to the CP.
It outputs the received call signal to U7 and also decodes and encodes the received call signal.
When a call is made from the ISDN telephone 3, a calling message is input from the CPU 7, and an outgoing call signal is input from the decoding/encoding section 9 and output to the bus wiring 1. The decoding/encoding section 9 decodes the received call signal and demodulates it into an audio signal under the control of the CPU 7, and outputs the signal to the handset 25.
It also has a codec function for encoding the outgoing call signal from the handset 25 and outputting it to the network connection section 5, and together with the network connection section 5 forms a transmitting and receiving section. The RAM 11 is a readable and writable memory in which the CPU 7 and others temporarily store data during processing.

The ROM 13 is a non-volatile memory that stores operating programs processed by the CPU 7 and response messages in the form of synthesized voices, which will be described later, and both read and write operations under the control of the CPU 7. Response messages include things like ``I'm on a business trip today. Please call back tomorrow.'' or ``I'm not available at the moment, so please call back in a while.'' That is, ROM13
functions as a response message storage. The schedule storage unit 15 associates the daily schedule of the person using the ISDN telephone 3 with the person's name, and records information such as presence, attendance, etc.
This is a schedule storage unit that stores transfers and absences, and is made of a readable/writable nonvolatile EEROM, for example.

For example, as shown in FIG. 2, the memory table stored in the schedule storage unit 15 shows that on *month*day, name A is "present" in the morning, name "out from 1:00 p.m." in the afternoon, and name B is "out from 13:00" in the morning. ``Meeting room number 123'', ``Present'' in the afternoon, and name C as ``On business trip until *month*day'' are stored.
It is stored under the control of the PU 7 and held until a deletion instruction is given from the input unit 19. The sub-address analysis unit 17 is a non-volatile memory that stores a program for analyzing the contents of sub-addresses in call messages, which will be described later.

[0013] As schematically shown in FIG. 3, the paging message is formed from terminal selection information such as message ID, transmission characteristics, channel ID, originating number, destination number, and sub-address, and is pre-standardized. It has a telegram format, and the storage contents of the message ID, transmission characteristics, channel ID, source number, and destination number are specified, but the user can store arbitrary code data for the subaddress. transmission is possible. Therefore, when using the ISDN telephone 3 of the present invention, it is sufficient to send the subaddress in the conventional calling message with the name of the person desiring to make a call.

[0014] The input unit 19 is, for example, a push button arranged on the main body case of the ISDN telephone 3, and inputs the name of the person to whom the call is desired regarding the originating number, destination number, and subaddress that form the calling message to be sent. At the same time, the name of the person using the ISDN telephone 3 and whether he or she is present, where he/she has moved to, or whether he/she is absent are entered in order to create a memory table as shown in Figure 2. be. The display section 21 is connected to the input section 19
In addition to arbitrary code data for the originating number, destination number, and subaddress entered in , the name of the person using the ISDN telephone 3, and the schedule corresponding to this name, the originating number at the time of incoming call, etc. This is a known example of a liquid crystal display device.

When the CPU 7 decodes the calling message and there is a number addressed to itself, the CPU 7 controls the connection of the network connection section 5 to the decoding/encoding section 9, and also refers to the sub-address analysis section 17 to assign an ISDN telephone to the sub-address in the calling message. 3, and when the name is detected, the schedule storage section 15 is referred to based on the name to search for a schedule. And the CPU
7 determines the meaning of the schedule of the searched name, that is, whether the name is present, transferred, or absent, and if the name is present, connects the network connection unit 5 and decoding/encoding unit 9 to secure the call, and transfers the call. If so, a calling message from the calling party with the destination phone number attached is output to the network connection unit 5 toward the destination phone, and if the phone is not available, an appropriate response message “I am on a business trip today. Tomorrow Please call again." and respond to the caller.

As described above, the CPU 7 and the subaddress analysis section 17 form a control section which is the main part of the present invention. In addition, the CPU 7 creates a calling message based on arbitrary code data for the originating number, destination number, and subaddress inputted in the input section 19, the name of the person using the ISDN telephone of the other party, and so on. As in the conventional case, it has the function of transmitting data to the other party's ISDN telephone via the connection unit 5 and the bus wiring 1.

Next, the operation of the ISDN telephone according to the present invention will be briefly explained. First, users A, B, and C
Enter the morning and afternoon schedules from the input section 19 of
Correspond to the name "A" and input "Are present" and "Out from 13:00", and correspond to the name "B" and input "Meeting room number 123" and "Present", and correspond to the name "C". When "I am on a business trip until *month*day" is input, the CPU 7 stores it in the schedule storage section 15 as shown in FIG. 2. In this state, as shown in Fig. 4, the calling party creates a calling message containing the number of the ISDN telephone 3, the number of its own telephone 3a, etc., and the name "A" of the person it wishes to call in the subaddress, and calls the ISDN telephone 3. When the call is sent from the ISDN telephone 3a, the call arrives at a plurality of ISDN telephones 3 and 3b connected to the bus wiring 1. Reference numeral 27 in FIG. 4 is an exchange.

In the ISDN telephone 3, the CPU 7 in FIG.
The subaddress in the call message is deciphered by referring to the subaddress, and the presence or absence of the user's name is checked in the subaddress to determine who the call is addressed to. When the CPU 7 detects the name "A", it refers to the schedule storage section 15, and if the incoming call is in the morning, it determines that the person is "present" and connects the network connection section 5 and the decoding/encoding section 9 to secure the call. The ringtone sounds and the handset 2
If you pick up 5, you can talk to the other party "A". If the incoming call is in the morning, it will be determined as a "transfer" and the call message from the calling side will be output to the network connection unit 5 with the destination telephone number attached to the destination telephone 3b.
A call message from A arrives at the ISDN telephone 3b with extension number "123", a ring tone sounds, and by saying one's own name and the name of the other party, one can talk to "A".

Furthermore, when the calling side creates a calling message in which the name "C" of the person to be called is stored in the subaddress and sends it from the ISDN telephone 3a, the CPU 7 decodes the subaddress, detects the name "C", and schedules the caller. It refers to the storage unit 15, determines that it is “absent”, and stores it in the ROM 13.
The response message ``I'm on a business trip today. Please try again tomorrow.'' is called from within the caller, and the caller is responded to. In this way, the ISDN telephone of the present invention stores the user's own name in the telephone that the user normally uses, and also has the ability to
By simply registering a schedule for absence, etc., incoming calls addressed to the user can be automatically processed according to the registered schedule.

[0020] Therefore, incoming calls to registered users are secured only when the presence schedule applies, and when other transfer schedules apply, they are forwarded to the designated forwarding destination, and when the absence schedule applies, a response message is sent. is sent. Therefore, even if the person who answered the called party's telephone does not know the schedule of the desired party on the calling party, the telephone itself knows the schedule, so the person who answers the telephone will have to wait several times while searching for the desired party. There is no need to say the name of oneself or the person on the other end of the call, and the trouble of searching for an absent person on the other end can be saved.

By the way, in the present invention, the data stored in the sub-address in the call message is not limited to the name, but can be implemented with any identification code such as an employee number or a unique call code, so that it can be used between users. The purpose of the present invention can be achieved by using an arbitrary identification code that has been agreed upon in advance. Further, the forwarding destination number stored in the forwarding destination data storage section 15 is not limited to a number, but may be any forwarding destination code that can identify the ISDN telephone. Note that the ISDN telephone according to the present invention can be applied not only to a telephone function but also to a telephone having ISDN terminal functions such as a so-called multi-function telephone function and a personal computer interface function.

[0022]

As explained above, the ISDN telephone of the present invention has an input section for instructing storage of arbitrary identification information and a schedule corresponding to the telephone, and a schedule memory for storing the arbitrary identification information and the schedule. When the transmitter/receiver receives an incoming call from the bus wiring, it extracts arbitrary identification information from the subaddress in the received paging message,
Since the configuration has a control unit that searches the schedule storage unit and performs processing corresponding to the schedule when a schedule corresponding to the arbitrary identification information is found, the user can display his or her arbitrary identification code on the telephone normally used by the user. Just by storing the schedule of the corresponding presence, incoming calls will be processed only when the person is present. In addition, if you store the transfer or absence schedule, the transfer will be processed when the transfer is applicable.
When the absence occurs, an appropriate response message is sent. Therefore, there is no need to search for an absent caller, and it is possible to take appropriate action according to the schedule.
