JP6024322B2 - Telephone system, telephone exchange, and message response method - Google Patents

Description

  The present invention relates to a telephone system, a telephone exchange, and a message response method.

  In recent years, telephone terminals such as PHS (Personal Handy-phone System) and mobile phones have been adopted as office extension telephones. When each user carries a telephone terminal, a telephone call comes to the telephone terminal regardless of where it is in the office.

  When the user is in a state where he / she cannot answer the phone, for example, a setting operation to the manner mode or the answering machine service mode is performed in advance on the telephone terminal. When an incoming call (incoming call) is received from the outside for a telephone terminal set in this way, for example, a predetermined automatic response message such as "I can't answer the call now" is played to the calling party. .

  Here, the automatic answering message is not always a fixed auto answering message such as "I can't answer the phone right now", but a phone terminal that can select any auto answering message from the standard auto answering messages There is also. Specifically, for example, “I ca n’t answer the phone during a meeting”, “I ’m eating now”, “I ca n’t answer the phone while driving”, etc. If the user designates (sets) a message that the user wants to use as an automatic response message, the designated automatic response message is reproduced to the calling party.

  In addition, there is a telephone terminal that can use the voice generated by the user himself as an automatic response message. When the user records the sound generated by the user in advance and designates the sound generated as an automatic response message, the sound generated is reproduced to the calling side.

  As a technique related to this, in Patent Document 1, in a state where a responder (recipient) of a receiving telephone cannot respond immediately when an incoming call is received, a scheduled response content after the state is resolved is indicated to the sender of the transmitting telephone. A receiver telephone that can be automatically answered by voice is described.

  Patent Document 2 describes a portable terminal device that can transmit an appropriate response message from the incoming side to the outgoing side with reference to the schedule. When there is an incoming call, the CPU of the mobile terminal device determines whether or not a schedule having a time zone including the incoming time exists on the RAM, and if there is, makes a line connection and corresponds to the schedule Read the response message from the ROM and send it to the line.

  In this way, instead of using a fixed automatic response message as an automatic response message, by responding to the calling side with an automatic response message corresponding to the user situation on the called side, the calling side It is possible to grasp in detail whether you can not answer the phone in a certain situation.

  However, the above-described telephone terminal and the receiving telephone set of Patent Document 1 require an operation (labor) of designating one message that the user wants to use as an automatic response message from a standard automatic response message or a voice-in. is there. For this reason, when it is necessary to attend the conference immediately, the operation for setting the automatic response message for the conference is not in time, and eventually, for example, a fixed automatic response such as “I can't answer the phone now”. A message was sometimes used.

  Moreover, according to the portable terminal device of patent document 2, since an appropriate response message can be used according to a schedule, the operation of designating one message can be omitted. However, if the schedule is not always met, there is a problem in that an automatic response message corresponding to the current user situation cannot be played back to the calling party. Specifically, for example, due to a sudden schedule change, there may be a case where “I am eating now” is reproduced according to the schedule, even though it is actually in a meeting.

  In the case of the above-mentioned telephone terminal and the receiving telephone set in Patent Document 1, the user himself / herself designates one message he / she wants to use. I can say that.

  The present invention has been made in view of such a problem. When the called party cannot omit the automatic response message selection operation, but the called party cannot answer the call, the called party receives the called party. An object of the present invention is to provide a telephone system or the like that can respond to an automatic response message according to the situation.

  In order to solve the above-described problems and achieve the object, a telephone system according to the present invention is a telephone system including a telephone terminal and a telephone exchange, and the telephone exchange is changed from the called telephone terminal to the called telephone terminal. A location information acquisition means for acquiring location information of the called telephone terminal, a storage means for storing a response message corresponding to each location information, and the called side Response means for responding to the caller telephone terminal with a response message corresponding to the location information of the telephone terminal.

  In addition, what applied the arbitrary combination of the component of this invention, expression, or a component to a method, an apparatus, a system, a computer program, a recording medium, etc. is also effective as an aspect of this invention.

  According to the present invention, the callee can omit the automatic response message selection operation, but can respond to the caller with an automatic response message according to the situation of the callee when the callee cannot answer the call. A telephone system can be provided.

[Location information management system]
First, since the telephone system according to the present embodiment uses position information, a position information management system for acquiring and managing the position information will be described first.

(system)
FIG. 1A shows a location information management system 1 according to an embodiment of the present invention. 1A includes communication apparatuses 100, 102, 104, and 106, wireless terminals 120, 122, and 124, a management apparatus 140, a management server 160, and a network 180 and a network 190 that include the communication apparatus, the wireless terminal, and the management apparatus. . Here, the network 180 is a wireless network managed by the management device 140. FIG. 1B shows the communication devices 100, 102, 104, and 106, the wireless terminals 120, 122, and 124, and the management device 140 that constitute the wireless network in FIG. 1A.

  The communication devices 100, 102, 104, and 106 are fixed to, for example, a ceiling of a room, and position information (hereinafter referred to as “position information”) such as history information, the number of floors of a building, and a building number related to the fixed position. This is transmitted wirelessly continuously or intermittently. Each communication device has an independent casing and operates by being supplied with power from a previously installed power source, or is incorporated in a lighting fixture such as an LED fluorescent tube and operates with power supplied from the lighting fixture. Each of the communication devices 100, 102, 104, and 106 transmits position information held by each of the communication devices 100, 102, 104, and 106 to a predetermined range using a radio signal. The predetermined range is determined by the signal strength of the radio signal used. The communication device is arranged so as to cover an area that is a position management target, and is configured so that the respective areas do not overlap. Or even if it is a case where it overlaps, in the side which receives a positional information, it is comprised so that any one communication apparatus can be determined based on the intensity | strength of a received radio wave. In the example of FIG. 1A, a conical dotted line shown below each communication device represents a predetermined range. As a communication method for transmitting position information, for example, a ground complementary signal (Indoor Messaging System; IMES) can be used.

  The wireless terminals 120, 122, and 124 can receive wireless signals transmitted by the nearest communication device among the communication devices 100, 102, 104, and 106. In the example of FIG. 1A, each wireless terminal is attached to a rectangular parallelepiped managed object that is a target whose position is to be managed. The wireless terminals 120, 122, and 124 are terminals that can transmit radio waves themselves, such as active tags. Hereinafter, the wireless terminal 120 will be described.

  The wireless terminal 120 is within a range where it can receive a wireless signal from the communication device 100 and receives position information of the communication device 100. The position information of the communication device 100 is received using, for example, IMES. The wireless terminal 120 transmits information including its own identification information such as a network address to the communication apparatus 100 together with the received position information. The transmission is performed through a network 180 by short-range wireless communication such as IEEE802.15.4 and ZigBee (registered trademark). In this case, IEEE802.15.4 abbreviated address or IEEE extended (MAC) address can be used as identification information of the wireless terminal 120. The identification information and position information transmitted to the communication device 100 are then transmitted to the management device 140 via the adjacent communication device 102. The transmission / reception operation in the wireless terminal 120 is performed at a timing determined in advance in the wireless terminal 120 or at a timing when a change in acceleration by the acceleration sensor included in the wireless terminal 120 is detected.

  The management device 140 connects the network 180 and the network 190 to each other, and bridges data transmitted from the network 180 side to the network 190. The management device 140 is installed, for example, for each floor of a building or for each room partitioned by walls. When the network 180 is a PAN (Personal Area Network) based on IEEE802.15.4 and ZigBee (registered trademark) and the network 190 is a LAN based on the IEEE802.3 standard, the communication system is converted between them. If the identification information of the wireless terminal 120 is represented by an IEEE 802.15.4 abbreviated address, it is converted into an IEEE extended address based on the information at the time of PAN configuration and transmitted to the management server 160.

  The management server 160 records the identification information and position information received via the management apparatus 140 together with the reception date and time, and manages the position of the communication apparatus. In the management server 160, management objects related to wireless terminals are recorded in advance. Therefore, the location of the management target can be searched using these pieces of information.

  The network 180 connects the respective communication devices 100, 102, 104, 106, the wireless terminals 120, 122, 124, and the management device 140, for example, a PAN configured by IEEE802.15.4 and ZigBee (registered trademark) standards. It is. When the PAN is configured with IEEE802.15.4 and ZigBee (registered trademark) standards, the wireless terminal, the communication device, and the management device each have an end device function, a router function, and a coordinator function defined by the ZigBee (registered trademark) standard. . Each communication device and wireless terminal enters the management of the management device at the time of activation, forms a PAN, and determines the minimum path to the management device.

  The network 190 is a network that connects the management apparatus 140 and the management server 160, and is, for example, a LAN defined by the IEEE 802.3 standard.

  As described above, in the location information management system 1 according to the embodiment of the present invention, the wireless terminal can transmit the identification information and the location information to the management server using power that can be communicated with the nearest communication device. it can. In addition, it is not necessary to install a new infrastructure for installing the communication device, and the introduction cost can be reduced.

  Note that the location information of the communication device may be provided through the network 180. This eliminates the need for transmission means for transmitting position information such as IMES.

  Further, the wireless terminal may transmit the identification information and the position information to the management apparatus 140 when the management apparatus is present in the vicinity of the communication apparatus that transmitted the position information. Thereby, identification information and position information can be transmitted to the management server by the shortest path.

  Further, the management server function may be integrated into the management server. This eliminates the need for a separate management device.

  The wireless terminal may be a wireless terminal having a function equivalent to an active tag, such as a smartphone, PDA, PC, or smart meter. As a result, it is possible to manage the position information of the existing wireless terminal without attaching a tag.

  Further, in addition to the above-described position information, information for specifying a finer position, such as information representing a section in the room, may be included. As a result, finer location management is possible.

  The location management target may be a person. Thereby, the location of a person can be managed by the system 1.

  The network 180 may be configured using short-range wireless communication such as Bluetooth LE, ANT, Z-Wave, and the like. This makes it possible to manage position information of various wireless terminals.

[Telephone system]
Next, the telephone system 2 according to the present embodiment will be described.

(system)
FIG. 10 shows the telephone system 2 in one embodiment of the present invention. A telephone system 2 according to the present embodiment includes the above-described position information management system 1. In the case of FIG. 10, specifically, the position information management system 1 includes communication apparatuses 100, 102, 104, 106, a wireless terminal 120, management apparatuses 140, 141, a management server 160, a network 180, and a network 190. Have. In addition, PHS slave units 130 and 131, a telephone exchange 150, and PHS master units 170 and 171 are connected to the network 190.

  In this embodiment, each user has its own wireless terminal and PHS slave unit. For example, user A (Mr. A) has a wireless terminal 120 and a PHS slave unit 130. Further, userB (Mr. B) has a wireless terminal 122 and a PHS slave unit 131.

  In the present embodiment, for example, the user always carries his / her own wireless terminal by means such as incorporating or adding a wireless terminal to the employee ID card. For this reason, the above-described position information management system 1 (management server 160) can grasp and manage the current position of each user by managing the position of the wireless terminal.

  The PHS slave units 130 and 131 are, for example, telephone terminals used as office extension telephones for each user. Each user can make a call with other PHS slaves using the PHS slaves that the user owns. The PHS slave units 130 and 131 have a manner mode (or answering machine service mode) function. For this reason, when the user is in a state where he / she cannot answer the phone, for example, the manner mode setting operation is previously performed on the PHS slave unit. A specific setting operation may be performed simply by pressing the manner mode button of the PHS slave unit. As a result, the PHS slave is in a manner mode valid state.

  If there is an incoming call (incoming call) from the outside to the PHS cordless handsets 130 and 131 set as described above, for example, “You cannot answer the call because you are currently in a meeting.” Cannot answer the call because it is in the middle "or" Cannot answer the call because it is currently in service. " (Details will be described later).

  In the present embodiment, the manner mode refers to a mode in which when an incoming call (incoming call) is received from the outside to the PHS slave unit, the incoming call is received and some automatic response message is returned to the calling party. . At this time, an automatic response message flows to the calling side.

  The telephone exchange 150 and the PHS master units 170 and 171 are facilities for enabling a call between the PHS slave units. The telephone exchange 150 is a control device (PBX) that connects a call between a caller and a callee and enables a call between PHS slaves. PBX (Private Branch Exchange) is a device that connects extension telephones and connects to a public line such as a subscriber telephone network or an ISDN line in a company or the like. The PHS master units 170 and 171 are radio base stations for extension telephones, and manage PHS slave units existing in their own areas. In the present embodiment, a total of two PHS master units PHS master units 170 and 171 are installed so that the wireless area is covered in all offices.

Normally, for example, when the PHS slave unit 130 makes a call to the PHS slave unit 131, a call is realized by the following operation (in normal call mode / non-manner mode).
(1) The PHS slave unit 130 dials the extension number of the PHS slave unit 131.
(2) The PHS master unit 170 having jurisdiction over the current area transfers the extension number dialed by the PHS slave unit 130 to the telephone switch 150.
(3) The telephone exchange 150 makes a call request to the PHS master unit 171 having jurisdiction over the area where the PHS slave unit 131 is located, based on the transferred extension number.
(4) The PHS master unit 171 calls all the PHS slave units existing in its own area all at once.
(5) Among these, the PHS slave unit 131 responds to the call.
(6) The PHS master unit 171 transfers the response of the PHS slave unit 131 to the telephone exchange 150.
(7) After passing through the authentication procedure of the PHS slave unit 131, the telephone exchange 150 connects the line from the PHS slave unit 130 to the PHS slave unit 131, and sends the other party's ringing tone (ringback tone) to the PHS slave unit The PHS slave unit 131 is made to ring.
(8) When the PHS slave unit 131 responds (presses the call start button), communication is started.
Thus, a call between both PHS slave units is realized.

(function)
Next, functions of the telephone exchange 150 according to the present embodiment will be described.

  FIG. 11 is a functional block diagram of the telephone exchange 150 according to an embodiment of the present invention. The telephone exchange 150 according to an embodiment of the present invention includes a call control unit 151, a position information acquisition unit 152, an automatic response unit 153, and a storage unit 154.

  In order to enable a call between the PHS slave units, the call control unit 151 connects the call between the calling side and the called side and controls the call between the PHS slave units.

  The location information acquisition means 152 indicates the current status of the user who owns the called PHS cordless handset to the management server 160 of the location information management system 1 when the called side PHS cordless handset is set to the manner mode. Queries the position information indicating the position, and acquires the position information. At the time of the inquiry, the identification information corresponding to the extension number (telephone number) of the PHS slave unit is specified with reference to the extension number correspondence table of the storage means 154. The identification information is identification information of the wireless terminal of the user who owns the called PHS slave. Using this identification information, the location information of the user who owns the called PHS cordless handset is inquired.

  The automatic response means 153 returns an automatic response message to the calling PHS slave when the called PHS slave is set to the manner mode. The automatic response message is responded by playing the audio file in the storage means 154.

  The storage unit 154 stores “extension number correspondence table”, “voice file management information”, and “voice file” in advance.

  The extension number correspondence table is a correspondence table in which an extension number (telephone number) of a PHS slave unit is associated with identification information of a user's wireless terminal that owns the PHS slave unit. The position information acquisition unit 152 uses the extension number correspondence table of the storage unit 154 when inquiring the location information of the user who owns the called side PHS cordless handset, and the radio of the user who owns the called side PHS cordless handset. Specify terminal identification information.

  The audio file management information is a correspondence table in which position information and audio files are associated with each other. When responding to the automatic response message, the automatic response means 153 refers to the audio file management information and determines the audio file to be reproduced based on the location information of the user who owns the called PHS slave.

  The audio file is a sound source file of an automatic response message. An automatic response message is replied to the calling PHS slave device by reproducing the audio file in the storage means 154. There are at least several patterns of auto-response messages.

  Note that a known configuration can be applied to the hardware configuration of the telephone exchange 150.

  FIG. 12 shows an example of the extension number correspondence table in one embodiment of the present invention. The extension number correspondence table is a correspondence table in which an extension number (telephone number) of a PHS slave unit is associated with identification information of a user's wireless terminal that owns the PHS slave unit.

  As described above, each user has its own wireless terminal and PHS slave unit. For example, user A (Mr. A) has a wireless terminal 120 and a PHS slave unit 130. The extension number of the PHS slave unit 130 possessed by userA is “0001”, and the identification information of the user's wireless terminal 120 possessed by userA is “002673abcdef01”. At this time, these pieces of information are registered in advance in association with the extension number correspondence table.

  FIG. 13 shows an example of audio file management information in an embodiment of the present invention. The audio file management information is a correspondence table in which position information and audio files are associated with each other.

  Specifically, for example, a room specified by position information of floor number: 16, latitude: 35.459555, longitude: 139.387110, ridge number: C in the office is a conference room. The audio file corresponding to this position is the audio file 1. Then, the automatic answering means 153 sets the location information of the user who owns the called PHS cordless handset to the conference room specified by the location information of floor number: 16, latitude: 35.459555, longitude: 139.387110, building number: C. If it is located, the sound file to be reproduced is determined as sound file 1.

  Further, for example, it is assumed that the position information of the user who owns the PHS slave on the called side is the position specified by the position information of floor number: 10, latitude: 35.459555, longitude: 139.387110, building number: C. In this case, even if the automatic response means 153 refers to the audio file management information, this position information does not correspond (the floor number is 10). Therefore, the automatic response means 153 determines the sound file to be reproduced as the position information: the sound file 4 associated with other than the above.

  In addition, for example, the location information of the user who owns the called PHS cordless handset is the location specified by the floor number: not obtainable, latitude: not obtainable, longitude: not obtainable, ridge number: not obtainable location information To do. That is, it is assumed that position information cannot be acquired. In this case, the automatic response unit 153 refers to the audio file management information, and determines the audio file to be reproduced as the audio file 5 associated with the position information: acquisition impossible.

  FIG. 14 shows the voice message content of a voice file in one embodiment of the present invention. The storage unit 154 according to the present embodiment stores five audio files of audio files 1 to 5 (for example, FIG. 11).

  For example, the voice file 1 has a voice message content “You cannot answer the phone because it is currently in a meeting” as shown in the figure. For this reason, when the automatic response means 153, for example, reproduces the voice file 1, an automatic response message “You cannot answer the call because it is currently in a meeting” is answered to the PHS slave on the called side. Will be.

  Also, for example, the voice file 4 has a voice message content “I can't answer the phone now”, as shown in the figure. As described above, in the audio file 4, the location information of the user who owns the called PHS cordless handset (for example, the room where the user is located) is not specifically specified or not specifically specified, such as a specific room. In this case, the audio file is played back. Therefore, the voice file 4 has the contents of a general voice message that does not include the location information of the user who owns the PHS slave on the called side with respect to the PHS slave on the calling side.

  Further, for example, as shown in the figure, the voice file 5 has a voice message content that “Today, we have already left the office. As described above, the audio file 5 is an audio file that is reproduced when the location information (for example, the room where the callee is located) of the called PHS slave cannot be obtained at all. When the location information of the user who owns the called PHS slave cannot be acquired at all, assuming that the office is under the management of the location information management system 1, the user who owns the called PHS slave Indicates that does not exist in the office. Therefore, the voice file 5 has a voice message content indicating that the user who owns the called PHS slave does not exist in the office with respect to the calling PHS slave. Note that the voice file 5 may also have other voice message contents such as “I am out of the office right now.

(Operation sequence)
FIG. 15 is a diagram showing an operation sequence of the telephone system 2 in the embodiment of the present invention in the configuration of FIG. In this operation sequence, the following scenario is assumed and explained for each step.
UserA (Mr. A) has a wireless terminal 120 and a PHS slave unit 130. userB (Mr. B) has a wireless terminal 122 and a PHS slave unit 131.
Since user B (Mr. B) is in a state where he / she cannot answer a call (during a meeting), the manner mode setting operation is previously performed on the PHS slave unit 131 (manner mode enabled state).
User A (Mr. A) uses the PHS handset 130 to make a call to the PHS handset 131 of userB. However, since userB's PHS slave 131 is in the manner mode, userA cannot make a call with userB.
・ Instead, an automatic voice message “You cannot answer the call because it is currently in a meeting” is sent to the PHS cordless handset 130, so user A is answered because user B is currently in a meeting. Recognize that there is no.

  This will be described in detail below.

  In S1500, the PHS slave unit 131 sets the manner mode. The user B only needs to press the manner mode button of the PHS slave unit 131 for a specific setting operation.

  In S1501, the PHS slave unit 130 dials the extension number of the PHS slave unit 131. As a result, the incoming call (call) is transferred to the PHS slave 131 side via the call control means 151 of the telephone exchange 150 or the like. At this time, since the PHS handset 130 is a side to make a call, it becomes a calling side telephone terminal, and since the PHS handset 131 is a side to receive a call, it becomes a called side telephone terminal.

  In step S1502, the PHS handset 131 receives the incoming call, but is in the manner mode valid state, and therefore responds to the call control means 151 of the telephone exchange 150 that it is in the manner mode (information indicating a state incapable of calling).

  In step S <b> 1503, the call control unit 151 of the telephone exchange 150 issues a location information acquisition command to the location information acquisition unit 152. At the same time, the extension number (for example, “0001”) of the PHS slave unit 131 is transmitted.

  In S <b> 1504, upon receiving the position information acquisition command, the position information acquisition unit 152 first identifies the identification information of the user's wireless terminal 120 that owns the called PHS handset 131.

  Specifically, the position information acquisition unit 152 refers to the extension number correspondence table in the storage unit 154. Then, the identification information “002673abcdef01” corresponding to the extension number “0001” of the PHS slave unit 131 is acquired (for example, FIG. 12).

  In step S <b> 1505, the position information acquisition unit 152 inquires of the management server 160 of the position information management system 1 about the position information of the wireless terminal 120 specified by the identification information (for example, “002673abcdef01”). Since the wireless terminal 120 is possessed by userA, the location information of the wireless terminal 120 indicates the current location information of userA.

  In step S1506, the management server 160 searches the location information of the wireless terminal 120 specified by the identification information based on the identification information. The management server 160 manages the position information of each wireless terminal using the position management information 368 (for example, FIG. 3D and FIG. 7). For this reason, it is possible to search the position management information 368 for the position information of the current position of the wireless terminal using the identification information of the wireless terminal as a key.

  Here, it is assumed that the floor number: 16, latitude: 35.459555, longitude: 139.387110, and building number: C are acquired as the location information of the wireless terminal 120 using the identification information “002673abcdef01” of the wireless terminal 120 as a key.

  In step S <b> 1507, the management server 160 returns the position information of the wireless terminal 120 to the position information acquisition unit 152.

  In step S <b> 1508, the location information acquisition unit 152 returns the location information of the wireless terminal 120 to the call control unit 151.

  In step S <b> 1509, the call control unit 151 issues an automatic response command to the automatic response unit 153. At the same time, position information (for example, floor number: 16, latitude: 35.459555, longitude: 139.387110, building number: C) acquired from the management server 160 is transmitted.

  In step S1510, the automatic response unit 153 acquires one audio file from the storage unit 154 based on the position information.

  Specifically, the automatic response unit 153 refers to the audio file management information stored in the storage unit 154 and identifies the audio file name associated with the position information. For example, when the position information is floor number: 16, latitude: 35.459555, longitude: 139.387110, building number: C, the sound file name associated with the position information is specified as “voice file 1”. At this time, “audio file 1” is acquired from the storage unit 154 (for example, FIG. 13).

  In step S1511, the automatic response unit 153 returns an automatic response message to the calling-side PHS slave unit 130. The automatic response message is responded by playing the audio file in the storage means 154.

  Here, “audio file 1” is reproduced as the automatic response message. When the automatic answering unit 153 reproduces the voice file 1, an automatic response message “You cannot answer the call because it is in a meeting now” is responded to the PHS cordless handset 130 on the called side ( For example, FIG.

  As described above, the telephone exchange 150 according to the present embodiment first possesses the PHS handset 131 using the location information management system 1 when the called PHS handset 131 is in a call-disabled state. Specify the current location of the user. When the current position of the user who owns the PHS slave unit 131 is specified, an automatic response message corresponding to the location information is returned to the PHS slave unit 130 on the calling side.

  Here, the automatic response message corresponding to the location information includes voice information of the current location of the user who owns the PHS slave unit 131. For this reason, the calling user not only does not answer the call by the auto answer message but also the specific reason (for example, during the meeting) and the current location (for example, in the meeting room). ) Can be recognized.

  On the other hand, when the PHS slave unit 131 is set to the manner mode, the specific setting operation may be performed only by the user B pressing the manner mode button of the PHS slave unit 131. Other operations, such as selecting the content of an automatic response message to be answered, are not necessary.

(Supplement)
In the above-described example, an automatic response message “You cannot answer the call because it is in a meeting now” is returned, but this is just an example. In addition, specifically, the position information of the user acquired from the management server 160 can be included in the voice information. In this case, for example, an automatic response message “You cannot answer the call because it is in the meeting room now” can be answered.

  In addition to responding to an automatic response message using an audio file, the response method includes a method of responding the same content as text data. In this case, on the display screen of the PHS cordless handset 130, “You cannot answer the call because you are currently in a meeting.” Or “You cannot answer the call because you are currently in a meeting room. "Can be displayed.

  In S1500, when the PHS slave unit 131 is set to the manner mode, the call control means 151 of the telephone exchange 150 notifies the PHS slave unit 131 that the manner mode is set (information indicating a call impossible state) at this time. You may make it notify. In this case, in 1501, it is possible to recognize that the PHS slave unit 131 is in the manner mode at the call control means 151 without the incoming call (call) being transferred to the PHS slave unit 131 side.

  In the above example, user B (Mr. B) has the wireless terminal 122 and the PHS slave unit 131. Here, in order to specify the current position of userB, who is the user who owns the PHS slave device 131, userB (Mr. B) needs to always wear and carry the wireless terminal 122. However, the PHS slave unit 131 is not limited to this. That is, as long as the PHS slave unit 131 is set to the manner mode, the user B does not always have to wear the PHS slave unit 131 and carry it. For example, the PHS handset 131 may be left on the desk during the meeting (this is a scene that is often seen). Even in this case, as long as the wireless terminal 122 is always worn, the current position of the user B carrying the PHS slave 131 is specified, and an automatic response message corresponding to the position is responded.

(Example of automatic response message)
FIG. 16 shows an example of an automatic response message in an embodiment of the present invention.

  (A): When the user having the called PHS slave unit 131 is in the conference room, “voice file 1” is reproduced as an automatic response message to the called PHS slave unit 130. That is, an automatic response message is sent to the PHS slave unit 130 on the called side, “You cannot answer the call because it is currently in a meeting”.

  (B): When the user who owns the called PHS slave unit 131 is in the conference room, “voice file 1” is notified to the called PHS slave unit 130 as an automatic response message. That is, an automatic response message (text data) is displayed on the display screen of the PHS handset 130 on the called side, “You cannot answer the call because it is in a meeting now”.

  Note that both (a) and (b) may be combined. In this case, an automatic response message “You cannot answer the call because it is in a meeting now” is answered with voice and text data.

  As described above, according to the present embodiment, when the called party can omit the automatic answer message selection operation but the called party cannot answer the call, the automatic answer message corresponding to the state of the called party is sent to the calling party. Can be provided. Note that the present invention is not limited to such specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims.

  In the above embodiment, an office extension telephone PHS terminal is applied as the telephone terminal. However, it goes without saying that the extension line and the outside line are not questioned, and the telephone terminal can be applied to a mobile phone, a portable information terminal (PDA, smart phone) and the like.
