Description

  The present invention relates to a telephone number processing apparatus, a control method, and a program.

  The mobile terminal network operator specifies FMC (Fixed Mobile Convergence) service that fuses the mobile phone network and the fixed telephone network as a merit of the FMC service provided by the mobile terminal carrier. All calls made between employees using mobile terminals are handled as calls made by extension, and even if calls between employees are outside the internal telephone network radio waves, no call charges (communication costs) related to the call are incurred. .

  That is, a call between mobile terminals contracted for an FMC service provided by a mobile terminal carrier is handled as an extension call even if the call is made at a location using the mobile phone network provided by the mobile terminal carrier. On the other hand, when one mobile terminal makes a call with a mobile terminal that is not subscribed to the FMC service, it is handled as an outside line call in which a call charge (communication cost) is generated by the outgoing call.

  Currently, a multi FMC service that integrates the FMC service provided by a carrier is provided, but when an employee uses the FMC service, an outside line that generates a call charge or an extension that does not generate a call charge Since the rules between operators are different in the operation, the following methods are disclosed.

  In Prior Literature 1, in order to link FMC services performed between a plurality of communication carriers, transmission position information is transmitted to the management table, the current transmission position is confirmed, and then the transmission position related to the user is related. The connection between FMC services among a plurality of communication carriers is realized by making a call request with a telephone number.

  In Prior Document 2, a priority is assigned to each telephone number assigned in advance to a telephone number assigned to a plurality of telephone numbers, and a number that is assumed to have the lowest telephone number charge is selected from the calling numbers for relay transmission.

  However, in the background art, when an employee who can use the FMC service provided by a mobile terminal carrier takes a mobile terminal outside the company and receives a call from a customer on the mobile terminal taken out from the company, he / she makes a call. Since the caller's outgoing number remains in the incoming call history of the mobile terminal, there is a risk of leakage of customer information if the mobile terminal is lost.

  Furthermore, when calling back to the customer with the incoming call number, since the number is 0, it is an outside line call via a general mobile phone network or public network, and the fact that the call is returned and the call data are used for company-specific calls. There is a problem that you cannot register online in the management system.

  Furthermore, when using the FMC service to make a return call with the incoming call number from the customer, for example, when making a call using the call number recorded on the mobile terminal, the call goes through a general mobile phone network or public network. Therefore, a call line such as in-house use, which is an advantage of the FMC service, cannot be selected, and the caller always selects 0 transmission. There are various problems.

Next, detailed IP telephone number processing of the IP telephone number processing apparatus 101 suitable for the telephone number processing apparatus of the present invention will be described with reference to FIGS.

  FIG. 4 is a flowchart showing an example of IP telephone number processing by the IP telephone number processing apparatus 101. Note that in steps S401 to S407, the CPU 3201 of the control unit 2201 of the IP telephone number processing device and instructions of the CPU 3201 communicate with the communication unit 2209, the determination unit 2202, the conversion unit 2207, the registration unit 2206, the search unit 2208, the control unit 2201, and the authentication unit. 2204 and the issuing unit 2203 execute.

  In step S401, the communication unit receives the transmission source number (customer number or extension number) and destination information (dial-in number or system number) transmitted from any IP-GW to the IP telephone number processing device (communication). Establish). The CPU 3201 of the control unit 2201 issues a temporary storage instruction to the work area of the RAM 3202 of the control unit, and the RAM 3202 temporarily stores it in the work area.

  In step S402, whether or not the number at the beginning of at least one of the source number (customer number or extension number) and destination number (dial-in number or system number) temporarily stored in RAM 3202 in S401 is “0”. Whether or not the determination unit 2202 determines. If the determination unit 2202 determines that the starting number is “0”, the process proceeds to S403. If the determination unit 2202 determines that the starting number is not “0”, the process proceeds to S406. Note that the determination process in step S402 may be performed only to determine whether or not the starting number of the transmission source number (customer number or extension number) is “0”. In this case, when the determination unit 2202 determines that the first number is “0”, the determination unit determines that the call is an external call originated by an external user outside the company (such as a customer or a person who does not use the FMC service). When the determination unit determines that the first number is not “0” (numbers 1 to 9), the determination unit 2202 is an internal that is transmitted by an internal user (employee or the person using the FMC service). Judge as outgoing. On the other hand, the same determination can be made in operation by determining whether or not the first number of the called number (dial-in number or system number) is “0” in step S402. This is because, in the case of an external call from an external user outside the company, since the destination is a dial-in number, the first number is “0”. In the case of an internal call from an internal extension telephone, the destination is an extension number. This is because the system number should be the destination even if the call originates externally. Then, in the case of an in-house telephone capable of outside line communication (permitted), it is conceivable that the first number of the destination is “0” (external call). Therefore, it is not necessary to convert the telephone number, and for this reason, it may be determined whether the first number of the called number is “0”. Although it is desirable to determine whether or not the first number of the caller (customer number or extension number) is “0”, in this embodiment, the caller number (customer number or extension number) and the incoming call The determination unit 2202 determines whether or not the first number of at least one of the destination numbers (dial-in number or system number) is “0”.

  In step S403, using the source number and destination number temporarily stored in RAM 3202 in step S401, the registration unit 2206 registers the received source number and destination number as a call history in the database (7101 in FIG. 7).

  In step S404, the CPU 3201 searches the external line information data (7102 in FIG. 7) of the registration unit 2206, and issues it when the customer number that is the caller source number does not exist in the external line information data (that is, it is a new customer number). The unit 2203 issues (acquires) a system number. This system number is a number of 11 digits or less whose initial number is not “0”. If the customer number is present in the outside line information data, the system number has already been issued and registered in the registration unit. The customer number and system number are the external line information data that uniquely correspond.

  In step S405, the registration unit 2206 registers the issued system number in the outside line information database (7102 in FIG. 7). Further, the CPU 3201 issues a temporary storage instruction to the work area of the RAM 3202, and the RAM 3202 temporarily stores the registered system number in the work area.

  In step S407, the search unit 2208 searches the extension information (7103 in FIG. 7) and the external line information (7102 in FIG. 7) for the extension number and the destination number, and the conversion unit 2207 converts the extension information and external line information. do. That is, the transmission source number and destination number received in S401 are registered in the extension information (7103 in FIG. 7) and the external line information (7102 in FIG. 7), and converted into the telephone numbers of the associated extension information and external line information, respectively. The transmission source number and the telephone number other than the destination number received in S407 are transmitted. As a result, the telephone number of the outside line transmission is converted into a number whose starting number is not “0” and is converted into the extension transmission. On the contrary, the telephone number of the extension transmission is converted into a number whose first number is “0” and is converted into an external transmission.

  In step S408, the CPU 3201 temporarily stores the RAM 3202 in the work area (1) customer number (external line information), (2) dial-in number (extension information), (3) system number (external line information), and (4) extension number. From the four telephone number information such as (extension information), the communication unit 2209 is instructed to transmit the transmission source number (system number or dial-in number) and the destination number (extension number or customer number). The communication unit 2209 transmits the transmission source number (system number or dial-in number) and destination number information (extension number or customer number) instructed to transmission to any appropriate IP-GW by routing according to a known technique.

  On the other hand, if the determination unit 2202 determines that the starting number is “0” in step S402, an inquiry process (to be described later in FIG. 8), which is a feature of the present invention, is performed in step S406. When this inquiry process ends, the process proceeds to the number conversion process in step S407.

  FIG. 5 is a flowchart illustrating the IP telephone number processing step in the IP telephone number processing apparatus 101 described in FIG. 4 and the IP telephone number actually used in the present invention in association with each other.

  In the example described here, a user X having a number “080-2222-2222” (customer number) dials a user Y who uses the FMC service having “050-1111-1111” (dial-in number). This is the case when making a call. When the apparatus is used, the user X can make a call only to the user Y when calling from the IP phone number “050”.

  The user X having the number “080-2222-2222” described here is preferably a general user. The general user here means that it is not an internal user such as an employee, which will be described later. Furthermore, the person who does not use the FMC service.

The number possessed by user X is not limited to a number such as 080, but may be a number whose initial number is “0”, for example, “090, 03, 095, 050, 070”.
Further, the terminal held by the user X may be not only a fixed terminal but also a portable terminal.

  In FIG. 5, “080-22222-2222” of the user X is transmitted from the mobile terminal 801 in FIG. 1, and the dial-in number “050-1111-1111” of the user Y who uses the FMC service is 601 in FIG. This will be described assuming that the mobile terminal receives the data.

  In step S501, the IP telephone number processing apparatus receives the source number “080-2222-2222” and the destination number “050-1111-1111” (established communication) from the IP gateway by routing that is a known technique.

  Step S502 represents the number temporarily stored in the RAM 3202 as described in S401. The source number is “080-2222-2222” and the destination number is “050-1111-1111”.

In step S503, as described in S402, the determination unit is “0” in the first numbers of both the transmission source number “080-2222-2222” and the destination number “050-1111-1111”. Is determined to be outgoing. Next, as described in S403, the registration unit 2206 registers the transmission source number “080-2222-2222” and the destination number “050-1111-1111” in the call history information data.
In step S504, as described in step S404, the issuing unit issues the system number “80001234”. This number is called the system number.

  Further, as described in S405, the registration unit 2206 registers “80001234” (system number) in the external line information database (1702 in FIG. 7). Here, “080-22222-2222” and “80001234” are associated with the outside line information data as outside line sender information.

  Here, the conversion unit converts the transmission source number from the number received in S501 into “80001234” (system number) associated with the outside line information as the transmission source number used when transmitting in S505.

  Similarly, the conversion unit converts the destination number from the number received in S501 into “4700001” (extension number) associated with the extension information as the destination number used when transmitting in S505.

  Here, “4700001” cited as the extension number can use the first number for identification of a communication carrier or the like. For example, if the first 4 of “4700001” is the identification number of the mobile terminal carrier A, and the first 6 of “6700001” (extension number) is the identification number of the fixed telephone carrier, Etc. can be identified, and can be used as a determination means. The starting number in this case may be any number from 1 to 9 as long as the number is not “0”.

Furthermore, if the first number is used to identify the carrier, the next number “700001” of 6 digits or less should be a number that can be used only within the FMC service provided by each carrier. Can do. In this case, the starting number may be any number from 1 to 9 as long as the number is not “0”. However, a number different from the identification number of the carrier is used.
The following can be said according to the configuration of the telephone number used in the above FMC service.
(1) “700001” is an extension number whose initial number is not “0” and can be used in the FMC service provided individually by each communication carrier.

  (2) “4700001” is an extension number whose initial number is not “0” that can be used in a multi-FMC service that includes a number that can be identified between telecommunications carriers, exceeding the FMC service for each telecommunications carrier. Is an extension number that can be used as

In step S505, the number temporarily stored in the RAM 3202 is described as described in the number conversion processing in step S407. The transmission source number is “80001234” and the destination number is “4700001” and is transmitted. In other words, in S501, the caller number “080-2222-2222” and the callee number “050-1111-1111” were converted, but both the caller number and the callee number were converted by the IP telephone number processing device. It will be. In other words, when the message was received, the starting number was “0”, but when transmitting, the starting number was converted to a number other than “0”.
In step S506, the IP telephone number processing device sends the source number and the destination number to the IP gateway by routing, which is a known technique.

  Steps S507, S508, and S509 are responses and represent responses from the user dial having “050-1111-1111”. The response here is a known technique. Thereafter, voice signals are communicated through the RTP session.

  FIG. 6 is a flowchart illustrating the IP telephone number processing step in the IP telephone number processing apparatus 101 described in FIG. 4 and the IP telephone number actually used in the present invention in association with each other.

  In FIG. 6, as described in FIG. 5, “080-2222-2222” (customer number) of the user X is transmitted from the mobile terminal 801 in FIG. 1 and “050-” of the user Y who uses the FMC service. “1111-1111” (dial-in number) will be described assuming that the user Y who uses the FMC service sends back to the user X after receiving from the mobile terminal 601 in FIG.

  In the example described here, the user Y who uses the FMC service having the number “050-1111-1111” (dial-in number) is “user X” who has “080-2222-2222” (customer number). It is a case where it sends to. That is, it is the reverse of the case described in FIG.

  The user Y who uses the FMC service having the number “050-1111-1111” described here is preferably an internal user such as an employee. When the user Y dials, Dialing is performed using a number whose starting number is not “0”, such as “80001234” (system number).

  Furthermore, all the caller source numbers when the internal users in the company make a call are internal user-specific numbers such as “4700001” (extension number) whose starting number is not “0”. Furthermore, the user Y who uses this FMC service knows in advance that the transmission source number when he / she makes a call is not “050-1111-1111” (dial-in number) but “4700001” (extension number). Suppose that

  Therefore, in this way, when users who use the FMC service want to talk with each other, by calling with an internal user dedicated number (extension number) whose starting number is not “0” such as “4700001”, Calls (internal calls) within the FMC service are possible. A known technology is used for a system in which the internal user dedicated numbers (extension numbers) communicate with each other.

“80001234” (system number) sent by user Y as a destination number may be dialed by a user using the FMC service by selecting a button, and if it has already been received, the number stored in the portable terminal is selected. May be sent. That is, when a user who uses the FMC service transmits the system number, the number only needs to be known.
Further, the terminal held by the user Y who uses the FMC service may be not only a portable terminal but also a fixed terminal.

  In step S601, the IP telephone number processing apparatus receives the source number “4700001” and the destination number “80001234” (establishes communication) from the IP gateway by routing that is a known technique.

  Step S602 represents the number temporarily stored in the RAM 3202 as described in S401. The source number is “4700001” (extension number) and the destination number is “80001234” (system number).

  In step S603, as described in S402, the determination unit determines that 0 is not included in the first numbers of both the source number “4700001” (extension number) and the destination number “80001234” (system number). The unit determines that the transmission is internal, and does not perform the processing of S404 and S405 but performs the processing of S406.

  In step S604, the number converted from the number received at S601 by the conversion unit is changed to “050-1111-1111” (dial-in number) associated with the extension information as the source number used when transmitting at S605. Convert.

  Similarly, the conversion unit converts the incoming call destination number from the number received in S601 to “080-2222-2222” (customer) associated with the external line information as the incoming call destination number used when transmitting in S605. .

In step S605, the number temporarily stored in the RAM 3202 is described as described in the number conversion processing in step S407. The transmission source number is “050-1111-1111” (dial-in number), and the destination number is “080-2222-2222” (customer number). That is, in S601, the caller number “4700001” (extension number) and the callee number “80001234” (system number) were changed, but both the caller number and the callee number were converted by the IP telephone number processing device. become. In other words, the initial number was not “0” when it was received, but it was converted to a number whose initial number was “0” when it was transmitted.
In step S606, the IP telephone number processing apparatus sends the source number and the destination number to the IP gateway by routing, which is a known technique.

Steps S <b> 607, S <b> 608, and S <b> 609 are responses and represent responses from the user dial having “080-2222-2222”. The response here is a known technique. After that, voice signal communication is performed by RTP session.
FIG. 7 is a data table used in the present invention.

Reference numeral 7101 denotes a call history table. In step S403, the registration unit 2206 registers the caller number and the callee number in the database as a call history using the caller number and the callee number temporarily stored in the RAM 3202 in step S401. The call history table is stored in the registration unit 2206 or the external memory 3211.
Reference numeral 7102 denotes an outside line information table.

  As explained in steps S404 and S405, when the registration unit searches the outside line information data and the customer number does not exist in the outside line information data (that is, a new customer number), the issuing unit automatically issues the system number. The issued system number is automatically registered in the outside line information database. There is no problem even if the customer number of the outside line information data and the system number are registered in advance before receiving the transmission source number and the destination information. The external line information table is stored in the registration unit 2206 or the external memory 3211.

  Reference numeral 7103 denotes an extension information table, and the registration unit registers the dial-in number and extension number of the extension information data in advance before receiving the transmission source number and the destination information. If there is a change or addition in the contents of the extension information, it may be corrected each time. The extension information table is stored in the registration unit 2206 or the external memory 3211.

  FIG. 8 is a flowchart showing an example of IP telephone number processing by the IP telephone number processing apparatus 101. The flowchart in FIG. 8 is for explaining the inquiry about the system number described in FIGS. 4 to 7, and is a flowchart for explaining the details of the inquiry process in step S406.

  In steps S801 to S807, the communication unit 2209, the determination unit 2202, the conversion unit 2207, the registration unit 2206, the search unit 2208, the control unit 2201, and the authentication unit according to instructions from the CPU 3201 and the CPU 3201 of the control unit 2201 of the IP telephone number processing device. 2204, the issuing unit 2203, the response unit 2205, and the input unit 2210.

  In step S801 (explanation of step S401), the communication unit 2209 transmits the source number (extension number or customer number) and destination information (inquiry number or dial-in) transmitted from any IP-GW to the IP telephone number processing device. Number or system number) (communication established). The CPU 3201 of the control unit 2201 issues a temporary storage instruction to the work area of the RAM 3202 of the control unit, and the RAM 3202 temporarily stores it in the work area.

  Here, it is assumed that the received caller telephone number is “4700001” (extension number), and the received callee telephone number is “888” (inquiry number). In this embodiment, “888” is used as the inquiry number. However, the present invention is not limited to this, and the first number is not “0” and a number that is not used as a system number or extension number. What is necessary is just to prepare as an inquiry number beforehand.

  In step S802, the determination unit 2202 determines whether the destination number (inquiry number or dial-in number or inquiry number) temporarily stored in the RAM 3202 in step S801 is the inquiry number. If the determination unit 2202 determines that it is an inquiry number (YES), the process proceeds to S803. If the determination unit 2202 determines that the number is not an inquiry number (NO), since the call originates from an extension telephone, the process proceeds to S407 in FIG. 4 to perform telephone number conversion processing.

  Further, when the determination unit determines that the inquiry number is used, the determination unit 2202 receives an internal user (an employee or the like who uses the FMC service) who knows the inquiry number from an internal user. It is determined as an inquiry.

  The inquiry number is a number that can be used only by the user who uses the FMC service, and is transmitted to the IP telephone number processing apparatus only from the terminal of the internal user.

  The inquiry number is an arbitrary number that can be determined by the determination unit to be an inquiry number, for example, “888” as long as the system administrator of the multi-FMC service assigns in advance as a destination number dedicated to the inquiry number. Good.

  Since the caller who is an internal user does not know the system number notified in step S807, the inquiry number “888” is set as the destination number. The transmission source number here is “4700001” which is the extension number of the internal user.

  In step S803, the response unit 2205 reproduces a pre-recorded or recorded reproduction message (instruction for receiving a destination number). The contents of the voice message reproduced here are the customer number, which is the intended destination number originally desired by the user, sent to the user of the telephone number processing device (the user who made the call) who is communicating. The user is prompted to perform manual input (dial operation).

In step S804, after transmitting the voice message in step S803, the input unit 2210 receives the destination number input by the user, and the input unit 2210 recognizes the received destination number as a customer number. The control unit issues an instruction to temporarily store the input customer number in the work area of the RAM 3202, and the RAM 3202 temporarily stores it in the work area.
The destination number received here is a “0 call” number used as a customer number, such as “080-2222-2222”.

  In step S805, the search unit 2208 searches for the customer number recognized in S804 in the external line information data (7102 in FIG. 7). Next, when the determination unit 2202 determines that there is no outside line information, the process proceeds to step S806. If there is, the determination unit 2202 determines that there is already external line information in which the customer number and the system number are uniquely associated, and the process proceeds to step S807.

  If the system number exists in the outside line information data, the customer number and the system number are already uniquely associated and registered in the registration unit before the communication. The customer number and the system number are external line information data that uniquely correspond to each other, and are registered (stored) in the registration unit. When newly registered, the information can be updated. This system number is a number of 11 digits or less whose initial number is not 0.

  In step S806, when there is no system number uniquely associated with the customer number, the issuing unit 2203 automatically issues a new system number of 11 digits or less whose starting number is not 0. Further, the registration unit 2206 registers the issued system number in the outside line information database (7102 in FIG. 7). Further, the CPU 3201 issues a temporary storage instruction to the work area of the RAM 3202, and the RAM 3202 temporarily stores the registered system number in the work area.

  In step S807, the response unit 2205 reproduces a response message that notifies the user of the system number stored in the RAM in step S806 (notification of the system number).

  Here, the content of the message reproduced by the response unit 2205 is a non-zero call that the user (sender) does not know to the user of the telephone number processing apparatus that is communicating (the user who made the call) The caller is notified of the system number, which is the destination number. Since the caller does not know the system number notified here, the caller sends the inquiry number as the destination number in step S801.

  In step S808, the response unit 2205 reproduces a response message for disconnecting communication to the user. The communication may be disconnected by the user, or the communication unit of the IP telephone number processing apparatus 101 may be disconnected.

  After the determination unit 2202 determines that the communication is disconnected, the CPU 3201 instructs the communication unit 2209 to transmit the transmission source number (extension number) and destination number (system number) temporarily stored in the work area by the RAM 3202. To establish each communication. At this time, at the time of requesting establishment of communication to the transmission source number (extension number), the IP telephone number conversion device establishes communication with the customer's system number as the transmission source. The communication unit 2209 transmits a transmission source number (extension number) and a destination number (system number) instructed to be transmitted to any appropriate IP-GW by routing according to a known technique.

  Here, the source telephone number to be transmitted is “4700001” (extension number), and the destination telephone number to be transmitted (incoming request) is “80001234” (system number). And it transfers to the telephone number conversion process of step S407 of FIG. Here, the IP telephone number converter connects the line established with the caller telephone number “4700001” (extension number) and the line established with the callee telephone number “80001234” (system number). Thus, it is possible to establish communication with a destination of a desired customer number by transmitting an inquiry number from an extension telephone that does not know the destination system number and connecting it to the system number. In this way, when there is an inquiry process, the IP telephone number converter establishes communication with each of the caller telephone number (extension number) and the destination telephone number (system number), and both lines for which communication has been established When connecting, the communication is established as an incoming call from the system number that is the destination telephone number to the caller telephone number, so that the customer's system number is assigned to the extension telephone terminal of the user who does not know the system number of the customer number. It is possible to register as a call history. As described above, as a mechanism for notifying the system number corresponding to the destination number to the extension telephone number of the caller that has made the inquiry request, a method of notifying by voice message as described in step S807, and step S808 Either of the methods using the system number at the time of disconnection / incoming call request (corresponding to the system number notification means) may be used.

  As described above, according to the present embodiment, when making a call from an extension telephone to an external telephone network, information that can identify the caller without leaving the telephone number of the caller of the external line in the extension telephone , As a call history, allows the user to know where the extension is calling, and can reduce the risk of leaking customer information even if the extension is lost, Even when the caller of the extension telephone does not know the information specifying the caller, it is possible to easily know the number specifying the caller.

In addition, when receiving an incoming call from an external telephone network to an internal telephone, the internal telephone side does not leave the telephone number of the external caller in the internal telephone, but leaves information that can identify the caller as a call history. The user can recognize where the call originates, and even if the extension telephone is lost, the risk of leakage of customer information can be reduced.
Also, the system number for converting the telephone number of the external telephone network can be registered when an incoming call for an extension number is received.

Further, the program in the present invention is a program that can be executed by the IP telephone number processing apparatus 101 or the information processing terminal in accordance with the processes of the flowcharts shown in FIGS. 4 and 8, and the storage medium of the present invention is the process in FIGS. The method is stored as an executable program.
