Description

  The present invention relates to a management apparatus, a management method, and a management program for managing incoming and outgoing calls between communication terminals.

  In recent years, a technique called FMC (Fixed Mobile Convergence) has been widely used. Here, FMC is a communication service that combines a desktop fixed telephone, a soft phone, and the like that perform wired communication with terminals such as a PHS (Personal Handy-phone System), a mobile phone, and a smartphone that perform wireless communication. By using FMC, it is possible to use not only desktop fixed telephones and soft phones that perform wired communication, but also, for example, PHS, mobile phones, and smartphones as extension telephones.

  Such technologies related to FMC are described in Patent Document 1 and Patent Document 2.

  In the technique described in Patent Document 1, a portable IP (Internet Protocol) telephone is used as an extension telephone. Specifically, the extension number of the portable IP telephone and the IP address are associated with each other and recorded in the extension number management table. When an incoming call is received for the extension number, the extension number table is referred to and an incoming call process is performed for the IP address corresponding to the extension number. Thereby, a portable IP telephone can be used as an extension telephone.

  By applying the technology using the IP address described in Patent Document 1, a smartphone or the like connected to an extension network such as a LAN (Local Area Network) can be used as an extension telephone. That is, the technique described in the cited document 1 can be said to be a technique of using a smartphone or the like as an extension telephone by performing communication within the extension network without going through an external network.

  However, in the technique described in Patent Document 1, when a smartphone or the like cannot be connected to an extension network such as a LAN, the smartphone or the like cannot be used as an extension telephone.

  In view of this point, in the technique described in Patent Document 2, a table in which telephone numbers of external lines such as smartphones are associated with extension numbers is stored in a telephone exchange connected to both the internal line and the external line. . A smartphone or the like is connected to the telephone exchange via an external line, and the telephone exchange converts the telephone number based on the table, whereby the smartphone or the like connected via the external line can be used as an extension telephone.

  Thus, by using FMC, many types of terminals can be used as extension telephones. Due to the spread of such technology, in recent years, employees have brought their own mobile phones to the workplace, and attempts have been made such as BYOD (Bring your own device) to specify such personal mobile phones for work. Yes.

  Against this background, in a company or the like, a single user (hereinafter referred to as “user A”) uses a plurality of wired or wireless telephone terminals that are communicably connected via a private branch exchange. Has become commonplace.

  However, for another user who wants to talk to user A and wants to make a call (hereinafter referred to as “user B”), any of the plurality of telephone terminals used by user A It is difficult to determine whether to make a call to a telephone number.

  In this regard, if it becomes possible to call a plurality of telephone terminals used by the user A with the same telephone number, the telephone number of which telephone terminal should be called for the user B who is making a call. There is no need to worry about whether it is good.

  In order to meet such needs, there is a technique for calling a plurality of telephone terminals with the same telephone number.

  An example of such a technique is described in Patent Literature 3 and Patent Literature 4, for example.

  In the technique described in Patent Document 3, the telephone exchange has a multi-ringing function. The multi-ringing function is a function for causing a plurality of telephones to receive a call simultaneously when an incoming call is received from a caller telephone set to a telephone set under an exchange equipped with the multi-ringing function. Then, the exchange enables a call between the telephone set that first goes off-hook after the incoming call and the caller.

  In particular, in the technique described in Patent Document 1, a plurality of telephones used by a certain user are set as targets of calling by the multi-ringing function. As a result, a plurality of telephone terminals used by a certain user can be called simultaneously with the same telephone number.

  On the other hand, the technique described in Patent Literature 4 describes that numbers of a plurality of telephone terminals are associated with each other and managed as a group in a table.

  According to the technique described in Patent Document 4, when an incoming call is received for a certain group, the above-mentioned table is referred to, and an incoming notification notification lamp for each of a plurality of telephone terminals associated with the certain group is provided. Blink. As a result, a plurality of telephone terminals can be called simultaneously with the same telephone number.

JP 2000-187224 A JP 2013-26832 A Japanese Patent Laying-Open No. 2015-56827 JP-A-3-278796

  By using each technique described above, a plurality of telephone terminals used by one user can be called by one telephone number. Further, by setting such one telephone number as an extension number, even if the type of the telephone terminal is a smartphone or PHS, it can be used as an extension telephone.

  By using the technology described in Patent Document 1 and Patent Document 2 described above, even if the type of the telephone terminal is a smartphone or PHS, it can be used as an extension telephone.

  Further, by combining the techniques described in Patent Document 3 and Patent Document 4 with this, a plurality of telephone terminals used by one user can be called with one extension number.

  However, the techniques described in Patent Document 3 and Patent Document 4 are only about processing when responding to one incoming call. In other words, in the technologies described in these patent documents, a call is made in response to one incoming call, or a call is made by calling from here, that is, a telephone terminal is used. In the meantime, it is not assumed that there is a possibility that there will be a new incoming call or a further call will be attempted by another telephone terminal not used for the call.

  Therefore, the present invention provides a management device, a management method, and a management program capable of managing other telephones while using one telephone when using a plurality of telephone terminals. Objective.

  First, an outline of an embodiment of the present invention will be described. Embodiments of the present invention are a plurality of telephone terminals (for example, desk fixed telephones, PHSs, softphones, and mobile phones) used by a certain user, which are connected to a private branch exchange (including a button telephone device). It is possible to call a telephone, etc.) with a single telephone number, and when calling from one of the plurality of telephone terminals, the caller telephone number to be notified to the other party is the same. To do.

  Thereby, in this embodiment, it becomes possible to handle a plurality of telephone terminals accommodated in the system as if they existed as one extension telephone terminal. Therefore, it is necessary for another user who wishes to make a call with a certain user to determine which telephone number among the plurality of telephone numbers assigned to the plurality of telephone terminals should be called. Disappear.

  However, when a certain user uses a plurality of telephone terminals with a single telephone number in this way, the other user who makes a call to the plurality of telephone terminals is such a certain user. To make a call.

  For this reason, it is not preferable that a certain user receives a new incoming call at another telephone terminal during a call at any one of the telephone terminals. This is because it is clear that a certain user makes a call or the like at any one of the telephone terminals and cannot respond to an incoming call from another telephone terminal. Further, since the incoming call is for such one user, other users should not respond at other telephone terminals. Furthermore, it is not preferable that another user uses a terminal that a certain user should use.

  Therefore, in the first embodiment described below, when one of a plurality of telephone terminals is calling / calling / answering an incoming call (except for an incoming call), the other telephone terminals are busy. Set the status (disabling / not receiving).

  Also, in the second embodiment described below, if a call is made to a predetermined telephone number, it is exceptionally possible that another telephone terminal can make a call. Here, the predetermined telephone number can be, for example, an emergency telephone number. For example, in the case of Japan, 110 (Police), 118 (Coast Guard), 119 (Fire and Ambulance), etc. in the United States If there is a telephone number such as 911 (Emergency telephone number).

  The above is the outline of the embodiment of the present invention.

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

[First Embodiment]
First, referring to FIG. 1, an incoming / outgoing call management system 1, which is the present embodiment, includes an incoming / outgoing call management apparatus 100, a first user terminal 201, a second user terminal 202, a third user terminal 203, a fourth A user terminal 204, an Nth user terminal 20N, a non-user terminal 301, an external network 400, and an internal network 500 are included.

  The incoming / outgoing call management apparatus 100 is an apparatus that manages incoming / outgoing calls of each terminal. The incoming / outgoing call management apparatus 100 has a function as a general telephone exchange. Furthermore, the incoming / outgoing call management apparatus 100 includes a function for managing incoming / outgoing calls using the association as a group unique to the present embodiment. The detailed configuration of the incoming / outgoing call management apparatus 100 and the function of managing incoming / outgoing calls unique to this embodiment will be described later with reference to FIG.

  The first user terminal 201 to the Nth user terminal 20N (N is a natural number of 2 or more) are telephone terminals used by the user of this embodiment. The first user terminal 201 to the Nth user terminal 20N can perform communication using extension numbers with other user terminals via the incoming / outgoing call management apparatus 100.

  Here, communication using such an extension number is realized using FMC. For this reason, there is no limitation as to what type of telephone terminal the first user terminal 201 to the Nth user terminal 20N are. That is, each of the first user terminal 201 to the Nth user terminal 20N includes various users such as a desk phone, a PHS, a soft phone incorporated in a personal computer, a portable IP phone, a smartphone, and a mobile phone. Realized by a terminal. Also, the first user terminal 201 to the Nth user terminal 20N may be the same type of telephone terminal, but may be different types of telephone terminals.

  In this embodiment, the extension number by FMC is used by cooperation of software for realizing the FMC function incorporated in the first user terminal 201 to the Nth user terminal 20N and the incoming / outgoing call management apparatus 100. Communication. Note that communication using extension numbers by FMC is a general technique as described in Patent Document 1 and Patent Document 2, and therefore, detailed description thereof is omitted.

  Further, the first user terminal 201 to the Nth user terminal 20N may be connected to the incoming / outgoing call management apparatus 100 via either the external network 400 or the internal network 500.

  As an example of connection, in the present embodiment, it is assumed that the first user terminal 201 is a telephone terminal (for example, a smartphone) that is connected to the incoming / outgoing call management apparatus 100 via an external network 400 (for example, a mobile phone network). On the other hand, the second user terminal 202 to the Nth user terminal 20N are connected to a telephone terminal (for example, a desk fixed telephone or a personal computer) connected to an extension network 500 such as a LAN (Local Area Network) used by the user. Assume that it is a built-in soft phone or a portable IP phone.

  In the following description, when any one of the first user terminal 201 to the Nth user terminal 20N is specified without being specified, it is simply referred to as a “user terminal”.

  The non-user terminal 301 is a telephone terminal used by a person other than the user who uses the user terminal of this embodiment. For example, if the user using the user terminal of the present embodiment is a company that uses the incoming / outgoing call management apparatus 100 and the extension network 500 in-house, the person using the non-user terminal 301 is the company The person of the customer.

  Here, in this embodiment, the incoming / outgoing call management apparatus 100 transfers the non-user terminal 301 connected externally via the external network 400 to the first user terminal 201 to the Nth user terminal 20N using the extension number. The function to connect is also realized.

  Specifically, for example, a technique called DID (Direct Inward Dialing) called by a name such as dial-in is used. In this case, a call is made to the extension number specified based on the correspondence by using the dial-in service of the communication carrier to associate the outside line number with the extension number. For example, the last 4 digits of the external line number are matched with the extension number, and the first user terminal 201 to the Nth user corresponding to the extension number that matches the lower 4 digits of the external line number as the destination of the non-user terminal 301 A call is made to the terminal 20N. When the users of the first user terminal 201 to the Nth user terminal 20N respond to such a call, a call using the extension number can be realized.

  In addition, as another method, for example, to a person who uses the non-user terminal 301 by sending an automatic guidance voice to the non-user terminal 301 connected to the representative number of the external line by the outgoing / incoming call management apparatus 100 Prompt for an extension number. Then, the incoming / outgoing call management apparatus 100 makes a call to the first user terminal 201 to the Nth user terminal 20N corresponding to the input extension number. That is, the call is transferred from the representative telephone number to the extension number. When the users of the first user terminal 201 to the Nth user terminal 20N respond to the transfer, a call using the extension number can be realized.

  As another method, a person in charge of the operator responds to the non-user terminal 301 connected to the representative number of the outside line. Then, the operator hears the extension number from the person who uses the non-user terminal 301, and the first user terminal 201 to the Nth user terminal corresponding to the extension telephone received by the incoming / outgoing call management apparatus 100 that received the input of the interviewed extension number. The user terminal 20N is called. That is, the call is transferred from the representative telephone number to the extension number. When the users of the first user terminal 201 to the Nth user terminal 20N respond to the transfer, a call using the extension number can be realized.

  The external network 400 is an external network, and is realized by, for example, a public switched telephone network (PSTN), an optical network, or a network provided by a mobile phone carrier.

  The extension network 500 is an extension network, and is realized by, for example, a telephone wiring laid in a user's office using this embodiment, or a LAN based on IP or the like.

  Next, functional blocks included in the incoming / outgoing call management apparatus 100 will be described in detail with reference to FIG.

  Referring to FIG. 2, the incoming / outgoing call management apparatus 100 includes a control unit 110, a terminal management table storage unit 120, an external line connection unit 130, and an internal line connection unit 140.

  The control unit 110 is a control unit that controls the entire incoming and outgoing call management device 100. Here, the control unit 110 includes, for example, a CPU (Central Processing Unit) for performing arithmetic processing, a ROM (Read Only Memory) that stores various control programs executed by the CPU, and the CPU executes the program. This is realized by a RAM (Random Access Memory) for storing data that is temporarily required for this. Then, in the control unit 110, the CPU reads various control programs from the ROM or other storage unit (not shown), and expands the read control programs in the RAM, while performing calculations based on these various control programs. Perform processing. And the control part 110 implement | achieves the function of the incoming / outgoing call management apparatus 100 by controlling the hardware in the incoming / outgoing call management apparatus 100 based on a calculation result. That is, this embodiment can be realized by cooperation of hardware and software.

  Here, as described above, the function of the incoming / outgoing call management apparatus 100 is a function as a general telephone exchange or a function of managing incoming / outgoing calls using association as a group specific to this embodiment. is there.

  The terminal management table storage unit 120 is a storage unit that stores a “user terminal management table” to be described later with reference to FIG. In addition to the user terminal management table, the terminal management table storage unit 120 may store programs used by the control unit 110 and other data.

  The external line connection unit 130 is a communication interface for communicating with each terminal (for example, the first user terminal 201 or the non-user terminal 301) connected to the external line network 400. On the other hand, the extension connection unit 140 is connected to each extension terminal 500 (for example, the second user terminal 202, the third user terminal 203, the fourth user terminal 204, and the Nth user terminal 20N). It is a communication interface for communicating with.

  The incoming / outgoing call management apparatus 100 realizes communication between user terminals connected to the external line connection unit 130 and the internal line connection unit 140 under the control of the control unit 110.

  Next, the contents of the user terminal management table stored in the terminal management table storage unit 120 will be described in detail with reference to FIG. The user terminal management table is a table used by the control unit 110 to manage incoming / outgoing calls using association as a group unique to the present embodiment.

  First, as a premise for explaining the user terminal management table, a method for managing user terminals by groups in the present embodiment will be described first.

  In the present embodiment, a plurality of user terminals are selected from the first user terminal 201 to the Nth user terminal 20N, and the selected user terminals are associated with each other and managed as one group. For example, the first user terminal 201, the second user terminal 202, and the third user terminal 203 are associated with each other and managed as one group. How the user terminals are selected and grouped is arbitrary, but for example, a user terminal used by a certain user outside the company (for example, a smartphone. In the present embodiment, the first user terminal) 201), a user terminal (for example, a portable IP telephone, which corresponds to the second user terminal 202 in the present embodiment) that the user carries and uses in the company, and the user owns the user terminal in the company. A user terminal (for example, a desk phone, which corresponds to the third user terminal 203 in the present embodiment) used at a desk is selected to form one group.

  When there is an incoming call to one extension number corresponding to the group, all user terminals included in one group are called. When a call is made from one user terminal corresponding to a group, one extension number corresponding to one group is notified to the call destination.

  By doing in this way, in this embodiment, it becomes possible to handle a plurality of user terminals included in a group as if they were one user terminal having the same telephone number.

  Referring to FIG. 3, the user terminal management table includes “group identification number”, “group state”, “user terminal extension number”, “user terminal communication information”, and “user terminal state” as attributes.

  Here, the “group identification number” is an identification number assigned to each group in order to identify each group. Hereinafter, each group is referred to as a group identification number. Referring to FIG. 3, for example, the group described at the top is the group identification number “first group”.

  “Group status” is information representing the current status of the group. Specifically, the group state stores whether the group is in an idle state or a non-idle state.

  In this embodiment, if all the user terminals in the group are in an idle state, the group state is in an idle state. On the other hand, if any of the user terminals in the group is in a non-idle state, the group state is in a non-idle state.

  If the group state is in the idle state, the incoming / outgoing call management apparatus 100 permits the user terminals in the group to answer the incoming call, make a call, or continue the accompanying call. On the other hand, if the group state is a non-idle state, the outgoing / incoming call management device 100 prohibits user terminals in the group from answering incoming calls, making outgoing calls, and continuing a call associated therewith. . That is, the incoming / outgoing call management apparatus 100 restricts the function of each user terminal if the group state is the non-idle state.

  Referring to FIG. 3, for example, the first group described at the top has a group state of “idle state”. This is because all the user terminals in the group are “idle”.

  On the other hand, referring to FIG. 3, for example, the second group described second from the top has a group state “non-idle state”. This is because the user terminals in the “non-idle state” are included in the group.

  If the state of the user terminal subsequently changes, these group states change accordingly.

  The “user terminal extension number” is an extension number assigned to each user terminal in the group. The user terminal extension number is a number unique to each user terminal. Referring to FIG. 3, for example, the first group described at the top includes three user terminals, and each of the three user terminals has a user terminal extension number of “100”. ", 101" and "102" are assigned.

  “User terminal communication information” is information required for the incoming / outgoing call management apparatus 100 to communicate with each user terminal. For example, when there is an incoming call from a certain user terminal to the first group, the incoming / outgoing call management apparatus 100 uses the user terminal communication information of each user terminal in the first group to Call the terminal. Thereby, an incoming call from a certain user terminal can be notified to each user terminal in the first group.

  The user terminal communication information includes, for example, information corresponding to the type of user terminal and the type of user terminal used for calling the user terminal.

  Referring to FIG. 3, for example, among the three user terminals included in the first group, the user terminal communication information of the user terminal with the user terminal extension number 100 described at the top is “type: external line” Telephone, outside line number: (090) -xxxx-xxx. Therefore, when calling / receiving the user terminal having the user terminal extension number 100, the incoming / outgoing call management apparatus 100 sends an external line to the external line number “(090) -xxx-XXX” and transmits the external network 400. Through.

  For example, among the three user terminals included in the first group, the user terminal communication information of the user terminal with the user terminal extension number 101 described in the middle is “type: IP phone, IP address: 198”. .168.0.xxx ”. Therefore, when calling / receiving the user terminal having the user terminal extension number 101, the incoming / outgoing call management apparatus 100 sends a call based on a protocol such as SIP to the IP address “198.168.0.xxx”. Etc. through the extension network 500.

  Further, for example, among the three user terminals included in the first group, the user terminal communication information of the user terminal extension number 102 described at the bottom is “type: fixed telephone, extension number”. : 102 ". Therefore, the incoming / outgoing call management apparatus 100 performs an extension call to the extension number “102” via the extension network 500 or the like in order to call the user terminal of the user terminal extension number 102.

  “User terminal status” is information indicating the current status of each user terminal. Specifically, the group state stores whether the group is in an idle state or a non-idle state.

  In this embodiment, the user terminal is (1) during a call made by the own user terminal, (2) after a call made by the own user terminal, during a call in response to a call destination response, and (3) the own user terminal In the case of three states during a call in response to a response to an incoming call, the user terminal state becomes a “non-idle state”.

  On the other hand, in other cases, the user terminal state is “idle state”. That is, when the call is not being made and the call is not in progress, or when the user terminal is receiving a call and has not yet responded to the call, the user terminal state is “idle state”. .

  In addition, it is as having mentioned above as description of a group state that a group state changes with the change of the user terminal state in a group.

  Next, the operation of the incoming / outgoing call management apparatus 100 in the present embodiment will be described with reference to FIGS.

  Here, FIGS. 4A and 4B illustrate incoming and outgoing call management when there is an incoming call using an external line number via the external network 400 from a non-user terminal (in this embodiment, the non-user terminal 301). FIG. 10 is a flowchart for exclusively explaining an operation when the apparatus 100 further connects the non-user terminal 301 and the first user terminal 201 to the Nth user terminal 20N using an extension number. FIG. When an incoming call is received from the non-user terminal 301 via the external network 400, the incoming / outgoing call management apparatus 100 further uses the extension number to connect the non-user terminal 301 to the first user terminal 201. As described above, the function of connecting to the Nth user terminal 20N is to input an extension number to a person who uses the non-user terminal 301 by sending out a DID or an automatic guidance voice by the incoming / outgoing call management apparatus 100. This process can be realized by the prompting process or the process in which the incoming / outgoing call management apparatus 100 makes a call to the first user terminal 201 to the Nth user terminal 20N corresponding to the extension number interviewed by the operator.

  FIG. 4-3 and FIG. 4-4 illustrate an operation when a call using an extension number is performed between user terminals (in this embodiment, the first user terminal 201 to the Nth user terminal 20N). It is a flowchart to do.

  Further, FIG. 4-5 is a flowchart for explaining the operation when the user terminal (in this embodiment, the first user terminal 201 to the Nth user terminal 20N) performs an outside line call using the outside line number.

  In the following description, the subject performing each process in each flowchart is the incoming / outgoing call management apparatus 100 controlled by the control unit 110 unless otherwise specified.

  Referring to FIG. 4A, first, it is determined whether or not a call from any user terminal has been accepted. If a call from any user terminal is accepted (Yes in step S1), the process proceeds to step S31 in FIG. 4-3. Here, the process after step S31 of FIG. 4-3 is mentioned later.

  On the other hand, when a call is not accepted from any user terminal (No in step S1), the process proceeds to step S3.

  In step S3, it is determined whether an incoming call to any extension number has been accepted. Here, when an incoming call to any extension number has not been accepted (No in step S3), the determination in step S1 is performed again.

  On the other hand, when an incoming call to any of the extension numbers is accepted (Yes in step S3), the process proceeds to step S5. Here, even though a call from any user terminal has not been accepted (No in step S1), an incoming call to any extension number has been accepted (No in step S1 and Yes in step S3). ) The call is made not by the user terminal but by the non-user terminal 301, and the call is received by any extension number.

  When the non-user terminal 301 makes a call using the external line number and the call is received via the external network 400, the incoming / outgoing call management apparatus 100 further uses the extension number to make the non-user terminal 301. Is connected to the first user terminal 201 to the Nth user terminal 20N by the above-described DID or a person who uses the non-user terminal 301 by sending out an automatic guidance voice by the incoming / outgoing call management apparatus 100. This can be realized by a process for prompting input of an extension number or a process for the incoming / outgoing call management apparatus 100 to make a call to the first user terminal 201 to the Nth user terminal 20N corresponding to the extension number interviewed by the operator.

  In step S5, the terminal management table storage unit 120 is referred to, and the extension number detected in step S3 and received or received by the incoming / outgoing call management apparatus 100, that is, the group corresponding to the extension number of the call destination is specified.

  Here, it is assumed that the extension number of the transmission destination is “100”, “101”, or “102”. Then, it can be specified that the group corresponding to the extension number of the callee in the incoming call in step S3 is the first group shown in FIG.

  On the other hand, it is assumed that the extension number of the call destination is “200” or “201”. Then, it can be specified that the group corresponding to the extension number of the callee in the incoming call in step S3 is the second group shown in FIG. Here, in the following description, it is assumed that the destination in the incoming call detected in step S3 is the first group shown in FIG.

  Next, it is determined whether or not the group state of the first group that is the destination group is an idle state (step S7).

  Here, when the group state of the first group is not the idle state but the non-idle state (No in step S7), it is said that any user terminal included in the first group has already made a call or the like. It will be. As described above, in such a case, in the incoming / outgoing call management process of the present embodiment, no other user terminal in the first group is called. Therefore, the process proceeds to step S9, where busy processing is performed on the non-user terminal 301 that is the transmission source.

  The busy processing in step S9 may be a general processing content, which is to send a busy tone to the non-user terminal 301 that is the transmission source and enter a waiting state for disconnecting the transmission source. When the busy process in step S9 is terminated, the current operation is terminated ("end" in FIG. 4-2).

  On the other hand, when the group state of the first group that is the destination group is in an idle state (Yes in step S7), the incoming call is notified to all user terminals included in the first group (step S11). ). That is, the user terminal extension number “100”, the user terminal “101”, and the user terminal “102” are notified of the incoming call. Specifically, the user terminal communication information is used to connect to each user terminal and cause each user terminal to ring. In addition, a lamp indicating an incoming call of each user terminal is blinked, or a message indicating an incoming call is displayed on the display unit of each user terminal.

  Next, before any user terminal responds to the incoming call notification, it is confirmed whether or not the non-user terminal 301 that is the transmission source interrupts the call (step S13).

  Here, when the non-user terminal 301 that is the transmission source interrupts the call before any user terminal responds to the incoming call notification (Yes in step S13), the first group that is the transmission destination group is changed to the first group. The incoming call notification to all the user terminals included (the user terminal whose user terminal extension number is “100”, the user terminal “101”, and the user terminal “102”) is canceled (step S15). Then, when the incoming call notification is canceled in step S15, the current operation is ended ("END" in FIG. 4-2).

  On the other hand, when the non-user terminal 301 that is the calling source does not interrupt the call (No in step S13), it is confirmed whether any user terminal responds to the incoming call notification in step S11 (step S17). .

  If none of the user terminals responds to the incoming call notification (No in step S17), the process of performing the determination in step S13 again is repeated.

  On the other hand, when any user terminal responds to the incoming call notification (Yes in step S17), the process proceeds to step S19 shown in FIG.

  In step S19, the terminal management table in the terminal management table storage unit 120 is referred to, and using the terminal communication information of the user terminal, the responding user terminal and the caller terminal are connected so that a call can be made. Thereby, the user of both terminals can talk (step S19).

  Here, in the present embodiment, during such a call, the functions of user terminals other than the responding user terminal included in the first group are limited. Specifically, the transmission by these other user terminals and the incoming call to these other user terminals are prohibited. For that purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the responding user terminal is rewritten to “non-idle state”. Accordingly, the group state of the first group is also rewritten to “non-idle state” (step S21).

  By doing so, even if there is an incoming call to the first group during a call, it is possible to return a busy state for the incoming call (No in step S7 and step S9). In addition, by doing this, even if there is a call from any user terminal included in the first group during a call, a busy state can be returned for such call (No in step S33 and step S33). S35). The detailed processing contents of steps S33 and S35 will be described later.

  Furthermore, since any user terminal has responded, there is no need to notify the other user terminals of incoming calls any more. Therefore, the incoming notification to other user terminals other than the responding user terminal included in the first group which is the destination group is canceled (step S23).

  Thereafter, it is monitored whether or not the call between the terminals connected in step S19 is terminated (No in step S25).

  If the call between the terminals connected in step S19 is completed (Yes in step S25), general processing associated with the call termination is performed. Further, after that, all user terminals included in the first group need to be in a state where transmission and reception can be performed.

  For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the responding user terminal included in the first group is rewritten to “idle state”. Accordingly, the group state of the first group is also rewritten to “idle state” (step S27).

  As a result, the current operation is terminated (“END” in FIG. 4B).

  While any of the user terminals in the group receives an incoming call by the process described in FIG. 4A and FIG. The terminal can be restricted from receiving incoming calls and making outgoing calls. As a result, for example, when one user uses each user terminal in the group, a new incoming call may be received even if a call is already in progress, It is possible to prevent the user terminal from being used.

  In addition, a person who makes a call to such a group does not need to worry about which of a plurality of extension numbers corresponding to a plurality of user terminals in the group should be called. It suffices to make a call to the user terminal.

  Furthermore, if a call is made to any one of a plurality of extension numbers corresponding to a plurality of user terminals in the group, the call can be made to all of the plurality of user terminals in the group. It is only necessary to tell a person to be performed any one of a plurality of extension numbers corresponding to a plurality of user terminals in the group.

  Next, referring to FIG. 4-1, FIG. 4-3, FIG. 4-4, and FIG. 4-5, the user terminal (the first user terminal 201 to the Nth user terminal 20N in this embodiment) The operation when making a call will be described.

  First, referring to FIG. 4A, as described above, it is determined whether a call from any user terminal has been accepted. If a call from any user terminal is accepted (Yes in step S1), the process proceeds to step S31 in FIG. 4-3.

  Next, referring to FIG. 4-3, in step S31, the terminal management table storage unit 120 is referred to, and the extension of the user terminal that made the call detected in step S1, that is, the extension number of the user terminal that made the call is set. A corresponding group is specified (step S31).

  Here, it is assumed that the extension number of the user terminal that made the call is “100”, “101”, or “102”. Then, it can be specified that the group corresponding to the extension number of the user terminal that made the call was the first group shown in FIG.

  On the other hand, it is assumed that the extension number of the user terminal that made the call is “200” or “201”. Then, it can be specified that the group corresponding to the extension number of the user terminal that made the call was the second group shown in FIG. Here, in the following description, it is assumed that the transmission source group, which is a group corresponding to the extension number of the user terminal that made the transmission, is the first group shown in FIG.

  Next, it is determined whether or not the group state of the first group that is the transmission source group is an idle state (step S33).

  Here, when the group state of the first group is not the idle state but the non-idle state (No in step S33), it is said that any user terminal included in the first group has already made a call or the like. It will be. As described above, in such a case, in the incoming / outgoing call management process of the present embodiment, no outgoing call is made by another user terminal of the first group. Therefore, the process proceeds to step S35, where the busy process is performed on the user terminal of the transmission source.

  The busy processing in step S35 may be a general processing content, and sends a busy tone to the user terminal of the transmission source and enters a waiting state for disconnecting the transmission source. In addition, when the result is No in step S33 and the process proceeds to step S35 as in this time, a busy tone is not transmitted, but “this user terminal is used because another user terminal in the group is already in use. A message such as “I can't do it” may be sent.

  In any case, when the busy process in step S35 is terminated, the current operation is terminated ("END" in FIG. 4-4).

  On the other hand, when the group state of the first group is the idle state (Yes in step S33), any user terminal included in the first group is not making a call or the like. Therefore, the process proceeds to step S37 without particularly performing busy processing.

  In step S37, it is determined whether the call destination is an extension or an external line based on the telephone number of the call destination detected in step S1.

  Here, if the call destination is an external line (No in step S37), as determined in step S33, the call source is in an idle state, and the external line is a restriction on outgoing / incoming calls in incoming / outgoing call management according to this embodiment. Since it is not a target, the process proceeds to step S65 in FIG. The processing after step S65 will be described later.

  On the other hand, if the destination is an extension (Yes in step S37), the process proceeds to step S39 in order to confirm the group state of the destination.

  In step S39, the terminal management table storage unit 120 is referred to, and a group corresponding to the extension number of the call destination detected in step S1 is specified. Here, it is assumed that the extension number of the transmission destination is “100”, “101”, or “102”. Then, it can be specified that the group corresponding to the extension number of the call destination detected in step S1 is the first group shown in FIG.

  On the other hand, it is assumed that the extension number of the call destination is “200” or “201”. Then, it can be specified that the group corresponding to the extension number of the call destination in the call detected in step S1 is the second group shown in FIG. Here, in the following description, it is assumed that the call destination detected in step S1 is the second group shown in FIG.

  Next, it is determined whether or not the group state of the second group that is the destination group is an idle state (step S41).

  Here, when the group state of the second group is not an idle state but a non-idle state (No in step S41), any user terminal included in the second group has already made a call or the like, It means that it is in a non-idle state. As described above, in such a case, in the incoming / outgoing call management process of this embodiment, the other user terminals of the second group are not called. Therefore, the process proceeds to step S35, and the busy process is performed on the user terminal of the transmission source in the first group.

  The busy processing in step S35 may be a general processing content, and it transmits a busy tone to the user terminal that is the transmission source and enters a waiting state for disconnecting the transmission source. When the busy process in step S35 is terminated, the current operation is terminated ("END" in FIG. 4-4).

  On the other hand, when the group state of the second group that is the destination group is an idle state (Yes in step S41), a process for notifying the second group of an incoming call is performed.

  Here, in this embodiment, while the user terminal of the transmission source included in the first group is transmitting, the functions of other user terminals included in the first group other than the transmitting user terminal are limited. Specifically, the transmission by these other user terminals and the incoming call to these other user terminals are prohibited. For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the user terminal that has transmitted is rewritten to “non-idle state”. Accordingly, the group state of the first group is also rewritten to “non-idle state” (step S43).

  Next, an incoming call is notified to all user terminals included in the second group (step S45). That is, the user terminal extension number “200” and the user terminal “201” are notified of the incoming call. Specifically, the user terminal communication information is used to connect to each user terminal and cause each user terminal to ring. In addition, a lamp indicating an incoming call of each user terminal is blinked, or a message indicating an incoming call is displayed on the display unit of each user terminal.

  Here, at the time of notification of this incoming call, all the user terminals included in the second group are also notified of the extension number of the caller. In this regard, the notified extension number is set to the same extension number for any user terminal included in the group. For example, when the user terminal having the extension number “100” included in the first group is the transmission source, “100” is notified as the extension number of the transmission source. Further, even if the user terminal having the extension number “101” included in the first group is the transmission source, “100” is notified as the extension number of the transmission source. Furthermore, even if the user terminal having the extension number “102” included in the first group is the sender, “100” is notified as the extension number of the sender.

  Upon receiving the extension number notification, the user terminals included in the second group display the notified extension number “100” of the caller on the display unit of the user terminal.

  By doing in this way, the several user terminal contained in a group can be utilized as one user terminal.

  Next, before any user terminal responds to the incoming call notification, it is confirmed whether or not the calling user terminal included in the first group interrupts the call (step S47).

  Here, if any of the user terminals included in the first group interrupts the call before any of the user terminals responds to the incoming call notification (Yes in step S47), the destination group is the first group. The incoming call notification for all user terminals included in the group 2 (the user terminal with the user terminal extension number “200” and the user terminal “201”) is canceled (step S49).

  Thereby, the transmission of the transmission source user terminal included in the first group ends. Therefore, after that, it is necessary to make it possible to send and receive calls at all user terminals included in the first group.

  For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the source user terminal included in the first group is rewritten to “idle state”. Accordingly, the group state of the first group is also rewritten to “idle state” (step S51).

  When the incoming call notification is canceled in step S49 and the rewriting in step S51 is terminated, the current operation is terminated (“END” in FIG. 4-4).

  On the other hand, when the calling user terminal included in the first group does not interrupt the call (No in step S47), it is confirmed whether any user terminal responds to the incoming call notification in step S45. (Step S53).

  If none of the user terminals responds to the incoming call notification (No in step S53), the process of performing the determination in step S47 again is repeated.

  On the other hand, when any user terminal responds to the incoming call notification (Yes in step S53), the process proceeds to step S55 illustrated in FIG. 4-4.

  In step S55, the terminal management table in the terminal management table storage unit 120 is referred to, and using the terminal communication information of the user terminal, the responding user terminal and the caller terminal are connected so that a call can be made. Thereby, the user of both terminals can talk (step S55).

  Here, in the present embodiment, during such a call, the functions of user terminals other than the responding user terminal included in the second group are limited. Specifically, the transmission by these other user terminals and the incoming call to these other user terminals are prohibited. For that purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the responding user terminal is rewritten to “non-idle state”. Accordingly, the group state of the second group is also rewritten to “non-idle state” (step S57).

  During a call, it is necessary to continue to restrict the functions of other user terminals included in the first group other than the source user terminal. The user terminal state and the group state of the first group are left in the “non-idle state”.

  By doing so, even if there is an incoming call to the first group or the second group during a call, a busy state can be returned for the incoming call (No in step S7 and step S9). In addition, by doing so, even if there is a call from any user terminal included in the first group or the second group during a call, a busy state can be returned for the call (step). No in step S33 and step S35).

  Furthermore, since any user terminal has responded, there is no need to notify the other user terminals of incoming calls any more. Therefore, the incoming call notification to other user terminals other than the responding user terminal included in the second group as the destination group is canceled (step S59).

  Thereafter, it is monitored whether or not the call between the terminals connected in step S55 is terminated (No in step S61).

  If the call between the terminals connected in step S55 is completed (Yes in step S61), general processing associated with the end of the call is performed. Further, after that, all user terminals included in the first group and the second group need to be in a state where transmission and reception can be performed.

  For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the source user terminal included in the first group is rewritten to “idle state”. Accordingly, the group state of the first group is also rewritten to “idle state”. Further, the user terminal state of the responding user terminal included in the second group is rewritten to “idle state”. Accordingly, the group state of the second group is also rewritten to “idle state” (step S63).

  As a result, the current operation is terminated (“END” in FIG. 4-4).

  Next, if No in step S37, that is, a step performed when there is a call using an external line number instead of an extension number from a user terminal to a non-user terminal or user terminal connected to the external line. The processing after S65 will be described with reference to FIG. In the following description, it is assumed that the call destination detected in step S1 is the non-user terminal 301.

  Here, in this embodiment, while the user terminal of the transmission source included in the first group is transmitting, the functions of other user terminals included in the first group other than the transmitting user terminal are limited. Specifically, the transmission by these other user terminals and the incoming call to these other user terminals are prohibited. For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the user terminal that has transmitted is rewritten to “non-idle state”. Accordingly, the group state of the first group is also rewritten to “non-idle state” (step S65).

  Next, the incoming call is notified to the non-user terminal 301 which is the transmission destination (step S67). Specifically, using the outside line number of the non-user terminal 301 received from the calling user terminal at the time of detecting the call in step S1, the non-user terminal 301 is connected and the ringing tone of the non-user terminal 301 is sounded. . In addition, a lamp indicating an incoming call of the non-user terminal 301 is flashed or a message indicating an incoming call is displayed on the display unit of the non-user terminal 301.

  Here, at the time of notification of this incoming call, the non-user terminal 301 is also notified of the outside line number of the caller. In this regard, the representative number of a company or the like in which the incoming / outgoing call management apparatus 100 and the extension network 500 are installed, and the external line number of the department to which the user terminal of the caller belongs are notified as the caller external line number.

  Next, before any user terminal responds to the incoming call notification, it is confirmed whether or not the calling user terminal included in the first group interrupts the call (step S69).

  Here, when the calling user terminal included in the first group interrupts the call before the non-user terminal 301 responds to the incoming call notification (Yes in step S69), the non-user terminal 301 Is canceled (step S71).

  Thereby, the transmission of the transmission source user terminal included in the first group ends. Therefore, after that, it is necessary to make it possible to send and receive calls at all user terminals included in the first group.

  For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the source user terminal included in the first group is rewritten to “idle state”. Accordingly, the group state of the first group is also rewritten to “idle state” (step S73).

  When the incoming call notification is canceled in step S71 and the rewriting in step S73 is terminated, the current operation is terminated ("end" in FIG. 4-5).

  On the other hand, when the calling user terminal included in the first group does not interrupt the call (No in step S69), it is confirmed whether or not the non-user terminal 301 responds to the incoming notification in step S45 ( Step S75).

  If non-user terminal 301 does not respond to the incoming call notification (No in step S75), the process of performing the determination in step S59 again is repeated.

  On the other hand, when the non-user terminal 301 responds to the incoming call notification (Yes in step S75), the process proceeds to step S77.

  In step S77, the responding non-user terminal 301 and the caller terminal are connected to each other using the external line number of the non-user terminal 301 received from the caller user terminal when the call is detected in step S1. As a result, the users of both terminals can make a call (step S77).

  During a call, it is necessary to continue to restrict the functions of other user terminals included in the first group other than the source user terminal. The user terminal state and the group state of the first group are left in the “non-idle state”.

  By doing so, even if there is an incoming call to the first group during a call, it is possible to return a busy state for the incoming call (No in step S7 and step S9). In addition, by doing this, even if there is a call from any user terminal included in the first group during a call, a busy state can be returned for such call (No in step S33 and step S33). S35).

  Thereafter, it is monitored whether or not the call between the terminals connected in step S77 is terminated (No in step S79).

  If the call between the terminals connected in step S55 is terminated (Yes in step S79), general processing associated with the termination of the call is performed. Further, after that, all user terminals included in the first group need to be in a state where transmission and reception can be performed.

  For this purpose, the terminal management table in the terminal management table storage unit 120 is referred to, and the user terminal state of the source user terminal included in the first group is rewritten to “idle state”. Accordingly, the group state of the first group is also rewritten to “idle state”. (Step S81).

  As a result, the current operation is terminated (“END” in FIG. 4-5).

  Through the processes described in FIG. 4-1, FIG. 4-3, FIG. 4-4, and FIG. 4-5 described above, one of the user terminals in the group makes a call, and then makes a call and makes a call. While another user terminal in the group receives an incoming call and then makes a call, other user terminals in the group are restricted from receiving incoming calls and making outgoing calls. can do.

  As a result, for example, when one user uses each user terminal in the group, a new incoming call may be received even if a call is already in progress, It is possible to prevent the user terminal from being used.

  In addition, a person who makes a call to such a group does not need to worry about which of a plurality of extension numbers corresponding to a plurality of user terminals in the group should be called. It suffices to make a call to the user terminal.

  In addition, if a call is made to any one of a plurality of extension numbers corresponding to a plurality of user terminals in the group, the call can be made to all the plurality of user terminals in the group. It is only necessary to tell a person who makes a call any one of a plurality of extension numbers corresponding to a plurality of user terminals in the group.

  Furthermore, the extension number of the caller that is notified when an incoming call is notified is common to any user terminal in the group. Therefore, when the called party makes a return call with reference to the incoming call history or the like, it is possible to call all the user terminals in the group of the common extension number by returning to the common extension number. .

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment to be described below, even if the group state of the group including the user terminal of the transmission source is “non-idle state”, if the call is made to a predetermined telephone number, an exception It is possible to make a call. Here, the predetermined telephone number may be an emergency telephone number, for example. Here, the emergency telephone number is also described above at the beginning of the description of the embodiment. It is a telephone number such as 911 (Emergency telephone number).

  For this reason, if there is a telephone that is not in use in front of you, it is convenient if you can make emergency calls such as call 119 if you are suddenly ill. It is because it improves more.

  Here, the configuration of the second embodiment is equivalent to the configuration of the first embodiment described with reference to FIGS. 1 and 2. Therefore, the description about the configuration of the second embodiment is omitted.

  Next, the operation of the second embodiment will be described. The operation when an incoming call is received from the non-user terminal 301 or the case where a call is made using the extension number between the user terminals using the extension number. The operation is substantially the same as that of the first embodiment. That is, the operation described with reference to FIGS. 4-1 to 4-5 is substantially the same as that of the first embodiment. However, the second embodiment differs from the first embodiment in that processing is newly added to the operation described with reference to FIG. This point will be described with reference to FIG. 5, which is a diagram in which processing is newly added to the operation illustrated in FIG. 4-3.

  As a premise for explanation, in the first embodiment, when a call from a user terminal is accepted (Yes in step S1), the process proceeds to step S31 in FIG. 4-3. However, in 2nd Embodiment, when the call from a user terminal is received (in step S1 Yes), it shall transition to step S31 of FIG.

  Referring to FIG. 5, step S91 is added as compared with the description of FIG. 4-3. This point will be described including the steps before and after step S91.

As in the first embodiment, a group corresponding to the extension number of the caller user terminal is specified in step S31 (step S31). Then, in step S33, it is determined whether or not the group state of the sender group is an idle state (step S33).
Here, when the group state of the transmission source group is an idle state (Yes in step S33), the operation is the same as in the first embodiment.

  On the other hand, when the group state of the transmission source group is not the idle state but the non-idle state (No in step S33), in the first embodiment, the process proceeds to step S35, and the transmission source user terminal is busy. We were processing.

  This means that if the group status of the source group is a non-idle state, any user terminal included in the source group has already made a call or the like. This is because calls by other user terminals included in the group are restricted.

  However, in the present embodiment, before the busy process is performed in step S35, it is determined in step S91 whether or not the destination telephone number is an emergency telephone number (step S91).

  If the destination telephone number is not an emergency telephone number (No in step S91), the process goes to step S35 to perform busy processing (step S35).

  On the other hand, if the destination telephone number is an emergency telephone number (Yes in step S91), the process proceeds to step S65 in FIG. 4-5. Then, by performing the processing after step S65, even a user terminal in a non-idle group can make a call to the emergency telephone number and make a call with the non-user terminal corresponding to the emergency telephone number Let me.

  As described above, in the second embodiment, by adding the determination in step S91, even if the group state of the group including the user terminal of the transmission source is “non-idle state”, a call is made to a predetermined telephone number. In some cases, it is possible to make an outgoing call.

  Therefore, if there is a telephone that is not in use in front of you, you can make emergency calls such as 119 calls when a suddenly ill person comes out, which can improve convenience. Become.

  The above-described two embodiments are preferred embodiments of the present invention, but the scope of the present invention is not limited to the above-described two embodiments, and various modifications can be made without departing from the scope of the present invention. It is possible to implement in the form that has been subjected to.

  As an example, various modifications will be described below. Each of the following modifications is the same as the above-described embodiment in basic configuration and operation. Therefore, in order to prevent duplication of explanation, hereinafter, configurations and operations unique to each modification will be described, and description of portions common to the above-described embodiments will be omitted.

<Modification>
First, one modification will be described with reference to FIG. FIG. 6 shows a terminal management table storage unit 120. Here, the terminal management table storage unit 120 illustrated in FIG. 6 is different from the terminal management table storage unit 120 illustrated in FIG. 3 in that an attribute “user terminal type” is added. The “user terminal type” stores information indicating whether each user terminal is a “main terminal” or a “sub-terminal”. A method of using such information will be described below.

  In step S5 and step S39, the group corresponding to the extension number of the call destination is specified. Here, in these steps, for example, when the extension number of the destination is “100”, “101”, or “102”, the group corresponding to the extension number of the destination is shown in FIG. It was specified that it was the first group represented by In the subsequent step, incoming calls are notified for all user terminals included in the first group.

  That is, regardless of whether the extension number of the destination is “100”, “101”, or “102”, the user terminal corresponding to all the extension numbers “100”, “101”, and “102” The incoming call was notified.

  In this modification, similarly, if the extension number of the call destination is the extension number of “main terminal”, the incoming call is notified to all user terminals included in the group. On the other hand, if the extension number of the call destination is the extension number of the “sub-terminal”, the incoming call is notified only to the user terminal of the “sub-terminal” corresponding to the extension number of the call destination.

  For example, when the extension number of the destination is “100”, which is the extension number of “main terminal”, all the extensions of “100”, “101” and “102” included in the first group The incoming call is notified to the user terminal corresponding to the number.

  On the other hand, when the extension number of the call destination is the extension number of “sub-terminal”, for example, “101”, only the user terminal corresponding to “101” included in the first group is notified of the incoming call. To do.

  Thereby, a person who uses only the number of the main terminal can use this modified example as in the above-described embodiments.

  In addition to this, a person who knows the number of the sub-terminal can call only the sub-terminal installed in the company in a situation such as “I want to talk if the other party is in the company”. Become.

  In order to realize these processes, in step S5 and step S39, it is specified whether the user terminal corresponding to the extension number of the call destination is the main terminal or the sub terminal together with the group corresponding to the extension number of the call destination. To do. If it is a sub-terminal, the incoming call notification destination may be limited to the user terminal corresponding to the extension number of the call destination in step S11 or step S45. Then, step S23 and step S59 may be omitted.

  In addition, when the user terminal of a transmission origin is a subterminal, you may deform | transform so that the extension number of the transmission origin notified to a transmission destination may be an extension number of a subterminal.

  Furthermore, another modified example will be described.

  The configuration illustrated in FIG. 1 is an example, and the number of user terminals and non-user terminals is not limited.

  Further, instead of sending a busy tone in step S9 or step S35, the incoming / outgoing call management apparatus 100 may perform a process of keeping a message. That is, processing as a so-called answering machine may be performed. And when the user terminal of the group corresponding to the extension number of a transmission destination becomes an idle state, it is good to be able to reproduce | regenerate this message.

  Further, when the group is in a non-idle state, a phrase such as “Currently unavailable because another user is in use” may be displayed on each user terminal included in the group.

  Further, during a call at any user terminal, the call may be transferred to another user terminal between groups. In this case, since the transfer destination user terminal is in the non-idle state, the group remains in the non-idle state. That is, even if it does in this way, the number of user terminals which can talk simultaneously within one group may be limited to one.

  Furthermore, when providing a service using each of the above-described embodiments, for example, the service may be provided by a name such as “one number forking”.

  Furthermore, the above embodiments and modifications may be combined without departing from the scope of the present invention.

  The incoming / outgoing call management device and each terminal included in the incoming / outgoing call management system can be realized by hardware, software, or a combination thereof. Also, the incoming / outgoing call management method included in the incoming / outgoing call management system and performed by the incoming / outgoing call management apparatus can be realized by hardware, software, or a combination thereof. Here, “realized by software” means realized by a computer reading and executing a program.

  The program may be stored using various types of non-transitory computer readable media and supplied to the computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD- R, CD-R / W, and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)).
