The voice / text communication system 1 according to the embodiment of the present invention is configured to be able to switch between a voice mode and a character mode according to a space where a mobile terminal that has received a call is located. That is, an antenna is arranged in each space to grasp the position of the mobile terminal, and the communication mode of the mobile terminal is set in the exchange according to the attribute of the space including the position and stored. Here, the space attribute indicates whether or not a voice call is permitted. For example, “speech or character” is set when permitted, and “character” is set when not permitted. When the mobile terminal receives voice data (incoming call) and the mobile terminal of the callee (calling side) is in the space of the space attribute “voice or text”, the exchange can make a voice call . On the other hand, when the destination mobile terminal is in the space of the space attribute “character”, the exchange converts voice data into character data and transmits it. At this time, it may be notified to the caller (calling side) that only characters can be sent to the callee, and the next response (voice / character conversion, contact by another method, etc.) may be selected. Further, a voice call by a specific source such as VIP can be made as it is without depending on the space of the destination. Note that it is not always necessary to accurately grasp the position of the mobile terminal. Basically, it is only necessary to identify the attribute of the space in which the mobile terminal exists.

≪System configuration and overview≫
FIG. 1 is a diagram showing a configuration of a speech text communication system 1. The spoken text communication system 1 can be applied in a predetermined area (for example, an office building, various facilities, a photographing site, a factory, an event venue, etc.) including inside a building and outdoors, and includes a portable terminal 2, an antenna 3, and an exchange 4 The administrator terminal 5 and the external terminal 6 are provided. The mobile terminal 2 is a mobile phone or the like possessed by a person who is active while moving within a predetermined area, and can transmit and receive voice calls and character data. The voice call mode and the character communication mode are manually set. (For example, a long press of an operation button or the like). The portable terminal 2 can be a voice call originator and destination. The antenna 3 is installed in each space within a predetermined area, relays data communication between the portable terminal 2 and the exchange 4, and notifies the exchange 4 of an antenna ID unique to the antenna 3. To do. For the space including the place where the antenna 3 is installed, the association between the space and the antenna ID of the antenna 3 and the space attribute of the space are set in the exchange 4.

  The exchange 4 can communicate with the mobile terminal 2 through the antenna 3, grasps the space where each target mobile terminal 2 is located through the antenna 3 at any time, and based on the space, the communication mode ( (Speech / text) is retained and updated. When the mobile terminal 2 receives an incoming call, if the communication mode of the mobile terminal 2 on the incoming call side is voice, the voice call is executed as it is, and if the communication mode is text, the fact is notified to the originating terminal. Notice. In response to this notification, when a voice / character conversion is instructed by the caller, the voice in the voice call is recognized, the recognized voice is converted into a character, and the converted character is converted into a short message or e-mail. 2 to send. In addition, a flag (VIP flag) is set to permit a voice call unconditionally to a specific caller out of the mobile terminal 2 on the extension line or the external terminal 6 on the outside call line. Enable unconditionally and forcibly. Further, the space attribute table is updated in accordance with an instruction from the administrator terminal 5.

  The administrator terminal 5 is installed in a department that manages the entire voice / text communication system 1, enables reservation and setting of attributes of each space together with a time zone, and transmits the setting contents to the exchange 4. As described above, the space attributes include “speech or character” and “character”. When a conference room is reserved, on the screen of the administrator terminal 5, for example, if “lecture” is designated in the auditorium which is one of the spaces, the “lecture” is “character” by the administrator terminal 5 or the exchange 4. And “character” is set in the space attribute of the auditorium in the exchange 4. This allows the user to designate the purpose of use of the space (lecture) without being aware of the space attribute, convert the purpose of use into an appropriate space attribute (character), and the exchange 4 stores the space attribute. In this way, the user-friendliness is improved. In addition, a part of the function for setting the space attribute is opened to a reservation system such as a conference room for general users as well as an administrator.

  The external terminal 6 is a terminal outside a predetermined area targeted by the voice / text communication system 1, and is, for example, an external telephone outside the company.

The terminal attribute 43A3 indicates whether or not the owner of the mobile terminal 2 responds to the incoming data. “Voice” may be a voice call, and whether the voice or text is left to the space attribute. “Character” indicates that character data is received regardless of the space attribute, but a voice call is not received. The position 43A4 indicates the position of the owner of the mobile terminal 2, and is used to determine whether or not the transmission source is the VIP of the transmission destination.

  FIG. 3B shows the data structure of the space attribute table 43B. The space attribute table 43B is a table related to the attributes of each space provided in a predetermined area, and includes a record for each space including a space name 43B1, a space ID 43B2, and a space attribute 43B3. The space name 43B1 indicates the name of the space, and is, for example, the shared unit 1, an auditorium, a conference room, or the like in the office building. The space ID 43B2 indicates an ID unique to the space, and may be, for example, the floor number of the space and position data on the floor, or may be an ID of the space corresponding to the ID unique to the antenna 3. The space attribute 43B3 indicates communication data that is allowed to be output by the portable terminal 2 for each time period in the space. For example, the shared section 1 such as a corridor is “voice or text” throughout the day, but a lecture is held. The auditorium is “character” between 9:00 and 11:00.

The antenna ID 43F1 is an ID unique to the antenna 3. The space ID 43F2 is an ID unique to the space including the place where the antenna 3 is installed. Since one or more antennas 3 are installed in one space, one or more antenna IDs 43F1 and one space ID 43F2 are associated with each other.

≪System processing≫
FIG. 5 is a flowchart showing table update processing of the exchange 4. This process periodically (at any time) transmits the terminal ID and terminal attributes stored in the mobile terminal 2 itself, and the terminal ID and terminal attributes received from the mobile terminal 2 by the antenna 3 and the antenna ID stored in itself. In the exchange 4, in the exchange 4, the communication unit 41 receives the terminal ID and terminal attribute of the portable terminal 2 and the antenna ID of the antenna 3 through the antenna 3, and based on the received data, the communication unit 41 The table update unit 42B sets and updates the table in the storage unit 43.

  First, the exchange 4 reads the position 43A4 in the terminal attribute table 43A specified from the received terminal ID, and sets the position 43C4 in the communication mode table 43C (S501). This reflects the position 43A4 of the terminal attribute table 43A that is updated asynchronously with the reception of the terminal attribute, etc., in the communication mode table 43C, and is not necessarily performed every time, and the update time of the position 43A4 is determined. For example, it may be performed once at that time.

  Next, the exchange 4 sets the received terminal attribute in the terminal attribute 43A3 of the terminal attribute table 43A specified from the received terminal ID (S502). This is because the terminal attributes of the portable terminal 2 are changed as needed according to the intentions of the owner, so that the exchange 4 periodically receives and updates the terminal attributes to always keep the latest state.

  Subsequently, the exchange 4 refers to the antenna space table 43F, identifies the space ID 43F2 from the received antenna ID, refers to the space attribute table 43B, identifies the space name 43B1 from the identified space ID, and determines the communication mode. The current position 43C2 of the table 43C is set (S503). Then, it is determined whether or not the terminal attribute 43A3 of the terminal attribute table 43A is a character (S504). If the terminal attribute 43A3 is a character (Y in S504), it indicates that the owner of the portable terminal 2 intends to respond to the character, so “character” is set in the communication mode 43C3 of the communication mode table 43C (S505). ).

  On the other hand, if the terminal attribute 43A3 is not a character (N in S504), it indicates that the holder of the portable terminal 2 intends to respond also to voice, so the exchange 4 changes the mode according to the space attribute of the current position. The communication mode 43C3 is set (S506). That is, with reference to the space attribute table 43B, the space name 43B1 is specified from the current position, and the attribute of the time zone including the current time is acquired from the corresponding space attribute 43B3. If the acquired attribute is “speech or text”, “speech” is set in communication mode 43C3 of communication mode table 43C.

  As described above, the communication mode corresponding to the terminal attribute of the mobile terminal 2 and the attribute of the space where the mobile terminal 2 is located at that time is set and updated in real time. According to this, when voice data is received by the mobile terminal 2, it is possible to immediately perform appropriate processing according to the communication mode.

  FIG. 6 is a flowchart showing the voice / character communication processing of the exchange 4. In this processing, when the communication unit 41 detects an incoming call (incoming call) to the mobile terminal 2 in the exchange 4, the response control unit 42C of the processing unit 42 performs voice or character communication processing according to the conditions. Is what you do.

  First, the exchange 4 acquires a source terminal ID and a destination terminal ID (S601). For example, the telephone number on the calling side and the telephone number on the called side are acquired from the IP packet received from the originating terminal. Then, it is determined whether or not the call originates from the VIP (S602). Specifically, first, it is determined whether or not the caller ID is set in the terminal ID 43C1 of the communication mode table 43C. If set, since the caller is the portable terminal 2 managed by the voice / text communication system 1, the position of the caller ID and the position of the callee ID are specified with reference to the communication mode table 43C, and the in-house VIP With reference to the table 43D, it is determined whether or not the position of the transmission source ID is a VIP of the position of the transmission destination ID. On the other hand, if it is not set, the source is an unmanaged terminal (external terminal 6), and therefore, referring to the external VIP table 43E, whether the source terminal ID is the VIP of the destination terminal ID or not. Determine whether.

  If the call originates from the VIP (Y in S602), the exchange 4 starts a voice call between the caller terminal and the callee terminal (S604). If the call is not from the VIP (N in S602), it is determined whether or not the communication mode of the callee ID is voice by referring to the communication mode table 43C (S603). If the communication mode is voice (Y in S603), a voice call is started between the caller terminal and the callee terminal (S604).

  If the communication mode is not voice (N in S603), the exchange 4 transmits to the sender terminal that the destination mobile terminal 2 is in character mode (S605), and performs voice / character conversion from the sender terminal. It waits for an instruction whether or not (S606). If there is an instruction (Y in S606) and the instruction does not perform voice / character conversion (N in S607), the process ends. In this case, the caller sends a short message or mail to the unique address of the mobile terminal 2 or does not contact the mobile terminal 2 but contacts the callee by another method such as a fixed telephone or PC mail.

  If the instruction from the transmission source terminal is to perform voice / character conversion (Y in S607), in the exchange 4, the response control unit 42C of the processing unit 42 activates the voice / character conversion unit 42D to activate the voice of the call. Is converted to characters (S608), and the response control unit 42C transmits the converted characters to the mobile terminal 2 that is the destination via the communication unit 41 (S609). If the voice / character conversion is selected, the exchange 4 informs the caller that the message to be sent to the destination should be spoken slowly so that voice recognition is possible. May be.

<Example>
FIG. 7 is a diagram illustrating an example in which an antenna is installed in an office. FIG. 7A shows the type of antenna. In the open space office SP1, an omnidirectional / small output antenna is used, and a voice call mode is set as standard. In the large conference room SP2, an omnidirectional / small output antenna is used, and the voice call mode is set as standard. A directivity / small output antenna is used in the meeting corner SP3 in the open space, and the character communication mode is set as standard. In the small conference room SP4, a directivity / small output antenna is used, and the character communication mode is set as standard. As the shared unit SP5, an omnidirectional / small output antenna is used, and a voice call mode is set as standard.

  As described above, an omnidirectional / small output antenna is used in a relatively wide space, and a voice call mode is set as a space attribute. The non-directional antenna is used because it is sufficient to know that the mobile terminal 2 is located in the space rather than accurately measuring the position of the mobile terminal 2. The voice call mode is set because it is considered that a voice call is allowed because a person is separated from each other to some extent due to a large space.

  On the other hand, a directivity / small output antenna is used in a relatively narrow space, and a character communication mode is set as a space attribute. A directional antenna is used because the position of a person is easily determined in a narrow space. Even if a directional antenna receives a radio wave from the mobile terminal 2 in the space, the spread of the radio wave is restricted. This is because there is little perception. The character communication mode is set because it is considered that a voice call is not permitted because a person is close to each other because the space is small. In a narrow space, a radio wave from a portable terminal 2 of a seated person is received by installing a directional antenna as close to a desk as possible (or installing a sheet-like antenna on the desk). Is preferred.

  The reason why the small output antenna is used is to avoid receiving the radio wave of the mobile terminal 2 from other than the space where the antenna is installed, and to easily specify the region where the mobile terminal 2 is located. However, by electromagnetically shielding the boundary between the space and the space, it is possible to receive only radio waves from the mobile terminal 2 in the space without necessarily using a small output antenna. For electromagnetic shielding, for example, a metal foil or metal mesh sandwiched between gypsum boards or the like is used. For examples of simple electromagnetic shielding, refer to Japanese Unexamined Patent Application Publication Nos. 2005-12054 and 2006-339592. In addition, when the antennas 3 in different spaces receive radio waves from the same portable terminal 2 (same terminal ID), the exchange 4 identifies the nearest antenna 3 based on the intensity of the received radio waves, and installs the antenna 3 It is conceivable to specify the space of the mobile terminal 2 from the location. Note that the location of the mobile terminal 2 is not limited to that based on the strength of the radio wave received by the antenna 3.

  FIG. 7B shows an example in which an antenna is arranged in an office space. Non-directional antennas are uniformly arranged in the relatively large office room SP1, large conference room SP2, and shared part SP5. On the other hand, only one directional antenna is disposed in the relatively narrow meeting corner SP3 and small conference room SP4. Basically, a simple electromagnetic shield is formed between the shared part SP5 and the rest, and the interior is designed to reduce leakage of radio waves. Further, the high-power antenna 3 may be used in the open space office SP1 to reduce the number of installed units.

  Antenna installation methods include ceiling installation, ceiling mounting, wall mounting, desk mounting, and lighting fixture incorporation. A wall-mounted terminal sheet can be made inconspicuous, for example, by attaching it to the back side of a painting or the like.

  FIG. 7C shows an example of a method for grasping the position of the mobile terminal 2. For example, it is conceivable that the large conference room SP2 is divided into two areas by the partition M, one area is set to the voice call mode, and the other area is set to the character communication mode. In such a case, the partition M is normally a curtain or the like and has no electromagnetic shielding effect. Therefore, in order to specify the area where the mobile terminal 2 is located and switch the communication mode according to the specified area, the mobile terminal 2 It is necessary to accurately grasp the position of. Therefore, for example, the distances a, b, and c between the portable terminal 2 and the three antennas 3 are measured, and the exchange 4 acquires the three distances, and based on these distances, the accuracy of the portable terminal 2 is determined. By identifying the correct position, it is determined in which area.

  In the above-described embodiment, in order to make each device (terminal and exchange) in the speech and text communication system 1 shown in FIG. 1 function, a program executed by a CPU built in each device can be read by a computer. It is assumed that the phonetic text communication system according to the embodiment of the present invention is realized by recording on a recording medium, causing the computer to read and execute the recorded program. In this case, the program may be provided to the computer via a network such as the Internet, or a semiconductor chip or the like in which the program is written may be incorporated in the computer.

  According to the embodiment of the present invention described above, the exchange 4 performs voice communication on voice data received at the mobile terminal 2 as it is according to the attribute of the space where the mobile terminal 2 is located in a predetermined area. Or the voice / character conversion is performed if there is an instruction to notify the caller that the voice is unavailable. According to this, when viewed from the owner of the mobile terminal 2, the communication mode of the mobile terminal 2 does not need to be manually switched, and automatically switches depending on the place, so that it is possible to spend without worrying about the communication mode. Can do.

When the voice data is received, the communication mode table 43C is referred to. However, at the time when the incoming call is received, the space where the called party is located is specified by communication with the mobile terminal 2 on the spot, and the attribute of the space is specified. Audio data may be processed according to the above.

(2) The space attribute of the space attribute table 43B is not set for each time as in the above embodiment, but has only the space attribute at the current time, and is updated as needed from the administrator terminal 5 according to the reservation table or the like. You may do it.

(3) In the above embodiment, it is determined whether or not the sender is a VIP for the sender according to the position of the sender and the position of the sender, but not only the position of the sender and the sender but also the destination Also, by considering the department to which the caller belongs, it may be determined whether the caller is a VIP for the callee based on the hierarchical relationship in the department. In addition, as in the outside VIP table 43E, in-house VIPs may be set for individual individuals. On the other hand, instead of the positions in the terminal attribute table 43A and the communication mode table 43C, for example, a VIP flag is set for the portable terminal 2 of a company executive, and when the incoming call is received, whether the terminal ID of the caller is VIP You may make it determine easily.

(4) In the above embodiment, the exchange 4 communicates with the mobile terminal 2 via the antenna 3 and specifies the location where the mobile terminal 2 is located based on the ID of the antenna 3. The position and location of the portable terminal 2 may be specified by For example, the exchange 4 communicates with the mobile terminal 2 having the GPS function without passing through the antenna 3, acquires the position data of the mobile terminal 2 measured by the GPS function, and based on the position data, The location of the mobile terminal 2 may be specified.
