  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a communication network system 100 to which a public / private metering system 1 according to an embodiment of the present invention is applied. A communication network system 100 shown in FIG. 1 is capable of communicating with each other between a public / private meter system 1 that performs a public / private meter service for communication, a communication device 10 used by a service user SC, and the public / private meter system 1 and the communication device 10. Communication network 20i (i = a, b,..., N). Hereinafter, the service provided by the public / private distribution system 1 to the service user SC is referred to as a public / private distribution service (also referred to as this service).

  The public / private distribution system 1 is a system built on a service provider SA that performs VOIP (Voice over Internet Protocol) service using SIP (Session Initiation Protocol), and uses this service to make outgoing calls. Service user by making communication of a subscriber SC (for example, a company employee, etc.) from a service contractor SB side (for example, a company, etc.) contracting this service using a mechanism described later. Even if the SC uses the private communication device 10, the entire communication of the service user SC can be grasped and the communication fee can be charged to the service contractor SB.

  FIG. 2 is a table explaining this. According to FIG. 2, a certain communication device (which is a personally owned mobile phone, the phone number of a private mobile phone is 090-XXXX-1234, and the IP phone number assigned by this service is 050-yyyy-5678. It is shown that the communication charges are clearly separated for each telephone number in public and private.

  The public / private distribution system 1 includes, in detail, a Web server 51, an authentication database (hereinafter referred to as an authentication DB) 52, an address book database (hereinafter referred to as an address book DB) 53, a network side outgoing server 54, an SIP server 55, and an accounting In this configuration, a database (hereinafter referred to as a charging DB) 56 is provided.

  The Web server 51 is a server that performs pre-processing of the service, authenticates the service user SC that uses the service, and gives the authenticated service user SC a function of changing the transmission source number and the telephone of the communication partner. Functions such as an address book in which numbers are recorded are provided. The service user SC is connected to the Web server 51 via the Internet network 20a from an authentication terminal 2j (j = a, b,..., N) described later.

  Further, the Web server 51 is linked to the network side transmission server 54, and transmits the information to the network side transmission server 54 when receiving the transmission source number and the communication partner number from the service user SC. . Here, the transmission source number is a telephone number for calling back to the service user SC from the network side transmission server 54 described later, and is freely set by the service user SC.

  Specifically, for example, as shown in FIG. 3A, the authentication DB 52 manages at least data items such as a service contractor ID, a service user ID, a password, and an IP telephone number. . Here, the service user ID and the password are referred to when the above-described service user SC is authenticated. Further, since the service user ID is managed in association with the service contractor ID, it is possible to grasp which service contractor SB the service user SC is at the time of authentication. Further, according to FIG. 3A, since the IP telephone number is assigned to each service user (more precisely, the IP telephone number group assigned to the service contractor SB is distributed to the service user SC. When this service is used, communication can be performed using this IP telephone number. That is, for example, even if this service is used using a private communication device 10 (for example, a mobile phone owned by the service user SC), the caller ID is this IP phone number. The communication device 10 does not display a private telephone number, but displays this IP telephone number.

  An address book DB 53 (not shown) is a database that manages an address book for each service user ID, and the address book includes at least items such as the name of a communication partner and a telephone number.

  Based on the transmission source number and the communication partner number received from the Web server 51, the network side transmission server 54 transmits SIP signaling to each communication device having the transmission source number and the communication partner number. The SIP server 55 is controlled. As a result, both the service user SC (caller) and the callee who use this service can communicate with each other as a callee with the assigned IP phone number.

  Further, the network side transmission server 54 is configured to receive the service user SC (caller) and the callee (the network side transmission server 54 and the service user SC (caller), and the network side transmission server). 54 and the callee's communication path are connected), the SIP server 55 is controlled so that the communication path between the service user SC (caller) and the callee can be connected and a call can be made. Yes.

  Note that such a function of the network side transmission server 54 is that, in a VoIP service using SIP, a call path using RTP (Real-Time Transport Protocol) is generated after call control using SIP signaling. After calling the service user SC (caller) and the callee from the side call server 54, the network-side call server 54 connects the communication path between the service user SC (caller) and the callee via both communication paths. It is what you do.

  The SIP server 55 is a server that manages a VoIP service using SIP, and controls from the start to the end of a call between a caller and a callee.

  The accounting DB 56 is a DB for recording the communication history of this service. For example, as shown in FIG. 3B, the accounting DB 56 includes items such as an IP telephone number, a service contractor ID, a call start time, and a call end time. As come to manage.

  The communication device 10 is a communication device used by a service user SC who uses this service. Specifically, an authentication terminal 2j (j = a, b,..., N) for receiving authentication of this service, and this service. The terminal 3k (j = a, b,..., N) for making outgoing calls and the incoming terminal 4l (l = a, b,..., N) for making incoming calls using this service are classified. The

  The authentication terminal 2j is assumed to be, for example, a mobile phone 2a and a personal computer 2b as shown in FIG. 1, but is not limited to this, and browser software is installed, and the Internet environment via the browser software, that is, Any connection is possible as long as it can be connected to the Web server 53 via the Internet network 20a. The browser function of the authentication terminal 2j improves the operability such as the change of the caller number and the selection of the communication partner described above.

  The caller terminal 3k is a communication device having a caller number set by a service user SC (caller), and receives a callback from the public / private distribution system 1. Here, since the caller number is set by the service user SC (caller) as described above, it is possible to set the telephone number of an arbitrary telephone (for example, a general telephone, a mobile phone, a PHS telephone, a VoIP telephone, etc.). It has become. In FIG. 1, the authentication terminal 2j and the transmission terminal 3k are displayed as physically separate terminals, but the authentication terminal 2j and the caller terminal 3k are treated as physically the same terminal. (For example, it is specifically a mobile phone having a browser function and a telephone function capable of responding to calls, and hereinafter, a terminal that serves as both the authentication terminal 2j and the caller terminal 3k communicates. Device 5m (m = a, b,..., N)).

  The callee terminal 4l is a communication device having a destination number, for example, specifically, a VoIP telephone connected to the VoIP network 20b, a general telephone connected to the PSTN / ISDN network 20c, and a mobile phone network 20c. A mobile phone connected to the terminal is assumed. That is, this service can be provided for communication devices 10 connected to any communication network 20 regardless of the terminal type.

  As described above, the communication network 20i is specifically composed of the Internet network 20a, the VoIP network 20b, the mobile phone network 20c, the PSTN / ISDN network 20d, and the like.

  The public / private meter system 1 and the communication device 10 described above include a central processing unit (CPU) having at least a calculation function and a control function, and a main storage device (memory) including a RAM having a function of storing programs and data. It is comprised from the electronic apparatus which has. In addition, the public / private meter system 1 and the communication device 10 may include an auxiliary storage device such as a hard disk in addition to the main storage device.

  A program for executing various processes according to the present embodiment is stored in the main storage device or the hard disk described above. The program can be recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, or a DVD-ROM, or can be distributed via a communication network.

  Next, the operation of the communication network system 100 to which the public / private accounting system 1 according to the present embodiment is applied will be described with reference to FIG. Here, FIG. 4 is a sequence diagram for explaining the exchange of communication between each component of the communication network system 100.

  First, user A (sender) who is a service user SC accesses the Web server 51 using the mobile phone 5a (step S10). The Web server 51 that has received access from the user A requests the service user ID and password from the user A (step S20). Here, FIG. 5A is a screen d10 for inputting the service user ID and password displayed on the mobile phone 5a.

  When the user A inputs the service user ID and password via the screen d10 shown in FIG. 5A and transmits them to the Web server 51, the Web server 51 refers to the authentication DB 52 and receives the received service usage. It is verified whether the user ID and password are correct (steps S30 and S40). When the service user ID and password are correct, the Web server 51 transmits a service menu screen d20 as shown in FIG. 5B to the mobile phone 5a (step S50). If the service user ID and password are not correct, the subsequent processing is not performed.

  When the user A sets a caller number from the service menu screen d20 shown in FIG. 5B (assuming that it is the phone number of the mobile phone 5a), and selects the phone book function on the service menu screen d20, Since the Web server 51 refers to the address book DB 52 and displays it on the address book screen d30 as shown in FIG. 5C, the communication partner (name, partner number) is selected from the address book screen d30 (for example, , User B is selected) and transmitted to the Web server 51 (step S60).

  The Web server 51 that has received the transmission source number and the destination number acquires the IP phone number of the user A from the authentication DB 52 and transmits it to the SIP server 55 (step S70). The SIP server 55 verifies whether or not the received IP phone number of the user A is available for service, that is, whether or not it is surely an IP phone number registered in the SIP server 55 (step S80). ). When the user A's IP phone number is available for service, the Web server 51 sends a message to that effect to the Web server, and the Web server 51 sends the user A's IP phone number, caller number, and destination to the network side call server 54. A transmission instruction command with a number is transmitted (steps S90 and S100). If the IP phone number of user A is not usable, the subsequent processing is not performed.

  First, the network side transmission server 54 transmits SIP signaling to the transmission source number of the user A via the SIP server 55 (step S110). Then, when user A goes off-hook in response to the call back from network-side transmission server 54, the fact that the user A has been off-hooked (that reception is possible) is transmitted to network-side transmission server 54 (step S110). When the network side transmission server 54 confirms that the caller A is in a receivable state, the network side transmission server 54 transmits a guidance (that the other party is being called) until the user B goes off-hook by calling the user B. (Steps S120 and S130). Note that when the caller A is not in a receivable state, the subsequent processing is not performed.

  Next, the network side transmission server 54 transmits SIP signaling to the number of the user B (called party) (step S140). Then, when the user B goes off-hook with respect to the call from the network side transmission server 54, the fact that the user B is off-hooked (that it can be received) is transmitted to the network side transmission server 54 (step S140). When the network side transmission server 54 confirms that the user B is in a receivable state, the network side transmission server 54 connects the communication paths in the RTP between the user A and the user B, thereby enabling a call between the two (steps). S160). At this time, the mobile phone 5a of the user A and the terminal 4a for the receiver B of the user B are notified of the calling number of the IP phone number of the user A. In addition, the call start time is recorded in the billing DB 56. When the call between the two ends, the network side transmission server 54 receives the SIP signaling, and the call end time is recorded in the accounting DB 56. If user B is not in a receivable state, the subsequent processing is not performed.

  By the way, in the above-described operation, after SIP signaling is transmitted to the user A (caller), the SIP signaling is transmitted to the user B (caller). ), The SIP signaling may be transmitted to the user A (sender). In addition, the guidance transmission in step S120 may be provided not only with the guidance that the other party is being called, but also with an advertising function, thereby reducing the call charge in this service.

  Furthermore, in the communication network system 100 to which the public / private accounting system 1 according to the present embodiment is applied, not only the two-party call described above but also a three-party call can be easily realized (for example, use with the user A) During the call of the party B, the user C is also called to make a three-party call). Steps S170 to S200 indicate this.

  While user A and user B are talking, user A selects a new communication partner (name, destination number) from address book screen d30 displayed on mobile phone 5a (for example, user C is selected) ) To the Web server 51 (step S170). Receiving the new destination number, the Web server 51 transmits a call instruction command with the destination number of the user C to the network side transmission server 54 (step S180).

  The network side transmission server 54 transmits SIP signaling to the destination number of the user C via the SIP server 55 (step S190). Then, when the user C goes off-hook with respect to the call from the network-side transmission server 54, the fact that the user C is off-hooked (that it can be received) is transmitted to the network-side transmission server 54 (step S190). When the network side transmission server 54 confirms that the user C is in a receivable state, the network side transmission server 54 connects the communication paths in the RTP of the user A, the user B, and the user C to connect the three parties. (Step S200). At this time, the IP phone number of the user A is notified to the calling party terminal 4b of the user C.

  As described above, in this embodiment, unlike a conventional instruction from a PB (Push Button) signal from a telephone, a simple procedure of selecting a communication partner from an address book displayed on the browser software is performed. It is possible to make a person call. Note that the number of other-party calls can be logically infinite unless there is a restriction on the bridge function of the public / private distribution system 1.

  Further, in the above-mentioned three parties, the user A instructs the public / private distribution system 1 with the telephone number of the user B as the calling party number and the telephone number of the user C as the destination number. It is also possible to make a call with the user C.

  While the embodiments of the present invention have been described above, various modifications and changes can be made to the embodiments of the present invention without departing from the spirit of the present invention. For example, although the present embodiment has been described on the assumption that the service contractor SB (for example, a company) and the service user SC (for example, an employee of the company) are different, the service contractor SB and the service Of course, the user SC may be the same person.

  In addition, this service may be further developed if it functions as an extension telephone in a company. For example, the address book DB 53 is an address book managed by all IDs (employees are managed by ID), and an ID-contact address correspondence table in which the current contact information of the service user SC is registered ( ID and employee contact information are managed in association with each other (can be set at any time by the employee). (Private number is not displayed) and privacy information may be protected. In this case, when there is an incoming call to the IP telephone number managed by this service, the ID corresponding to the IP telephone number is referred to connect to the currently bound contact.

  The authentication terminal 2j in the present embodiment accesses the Web server 51 via browser software and uses the authentication function, the sender number change function, the address book function, and the like. In order to improve the operability, for example, an application created in the Java (registered trademark) language is loaded from the Web server 51 to the authentication terminal 2j (the execution environment of the program created in the Java (registered trademark) language is provided. And an authentication function, a sender number change function, an address book function, and the like may be activated using the application.
