Description

  The present invention relates to a technique for de-billing a call when a failure accompanied by a call disconnection occurs in a relay apparatus that relays control information for establishing a call transmitted / received between communication terminals.

2. Description of the Related Art Conventionally, in a relay device, when the relay device recovers from a failure, there is a technique for de-billing the communication time before recovery from the failure by transmitting a charging time reset signal to the detail generation device ( Patent Document 1).
In such a technique, the relay device and the detail generation device communicate using, for example, SIP (Session Initiation Protocol) as a communication protocol.

  In SIP, when a call is established between a caller communication terminal and a callee communication terminal to perform communication (call), the caller communication terminal sends a SIP message such as an INVITE request to the callee communication terminal. Send to communication terminal. On the other hand, the called communication terminal transmits a SIP message such as a 200 OK response to the INVITE request to the calling communication terminal. At that time, these SIP messages are relayed by a plurality of relay devices and detail generation devices for interconnecting the calling side network and the called side network. Then, after the call is established, a speech path is formed by the plurality of relay devices and the detail generation device.

  Conventionally, there is the following technique as another technique for performing non-billing processing in a non-billing processing system using SIP. In such a technique, when a failure with call disconnection occurs in a certain relay device among a plurality of relay devices that form a communication path, a header indicating non-billing is provided from the failed relay device to the detail generation device. The added BYE request (hereinafter referred to as non-billing BYE) is transmitted. As a result, the target call is not charged. Further, in this technique, as shown in FIG. 13, it is assumed that BYE is transmitted from the calling side while the relay apparatus C in which the failure has occurred is being restored. Then, as illustrated in FIG. 13, it is assumed that the order generation apparatus receives the BYE from the calling side in the order of arrival of signals before the relay apparatus C that is being restored. In this case, it is necessary to repeatedly retransmit BYE to the relay apparatus C being restored and wait for a response from the relay apparatus C being restored before determining the non-billing period. Specifically, as shown in FIG. 13, the relay device B sends a response to the BYE request from the detail generation device as a 200 OK response (hereinafter referred to as a non-chargeable header) from the failed relay device C. , 200 OK (referred to as non-billing)).

JP 2010-251835 A

  However, in the prior art in which non-billing is performed using the non-billing BYE and 200 OK (non-billing), the non-billing BYE and 200 OK (non-billing) are transmitted through the communication path. Therefore, for example, when a double failure or the like occurs in the communication path, there is a case where the non-billing BYE or 200 OK (non-billing) does not reach the detail generation device and the non-billing process cannot be performed.

  Further, as shown in FIG. 14, a general-purpose device adopting SIP normally returns a 200 OK response as soon as a BYE request is received. Therefore, when a SIP-compatible general-purpose device is used as it is, there is a possibility that a section that should not be charged becomes a charging section as shown in FIG. Accordingly, as shown in FIG. 13, when the non-billing period is determined after waiting for a response from the recovering relay device, it is necessary to control the transmission and reception of control information between the devices.

Here, FIG. 12 is a sequence diagram showing an operation from the establishment of a call until the billing details information is transmitted to the non-billing processing device 30.
As shown in FIG. 12, when INVITE is transmitted from the mobile communication terminal 40 on the calling side to the relay device 10A (step S400), the relay device 10A identifies the identification information of its own device 10A (in the header portion of the received INVITE ( Here, the IP address (1)) is added, and the INVITE to which the IP address (1) is added (hereinafter referred to as INVITE (1)) is transmitted to the relay device 10B (step S402).

  Specifically, when the identification information adding unit 100 determines that the relay device 10A has received the SIP message (INVITE) (Yes in step S100), the relay device 10A uses the reception order information stored in advance in the ROM or the storage device 10A. Is determined to receive INVITE before the detail generation device 20 (Yes in step S102). Further, when the identification information adding unit 100 determines that the received SIP message is INVITE (Yes in step S104), the IP address (1) of the own apparatus 10A is added to the header part of the received INVITE (step S106). . The identification information adding unit 100 adds only the IP address (1) of the own device 10A to the header portion because the relay device 10A receives the INVITE from the mobile communication terminal 40 on the calling side before other relay devices.

Then, an INVITE to which the IP address (2) is added (hereinafter referred to as INVITE (1) (2)) is generated. Then, the generated INVITE (1) (2) is transmitted to the detail generation device 20.

  Specifically, when the identification information adding unit 100 determines that the relay device 10B has received the SIP message (INVITE (1)) from the relay device 10A (Yes in step S100), the relay device 10B is stored in advance in the ROM or the storage device. From the reception order information, it is determined that the own device 10B receives INVITE before the detail generation device 20 (Yes in step S102). Further, when the identification information adding unit 100 determines that the received SIP message is INVITE (Yes in step S104), the IP address of the relay device 10A included in the header portion is included in the header portion of the INVITE (1) ( In addition to 1), the IP address (2) of its own device 10B is added to generate INVITE (1) (2). The relay device 20 transmits the generated INVITE (1) (2) to the detail generation device 20 in the SIP message transmission unit 102.

  Specifically, when the identification information adding unit 100 determines that the SIP information (INVITE) has been received by the identification information adding unit 100 (Yes in step S100), the relay device 10C uses the reception order information stored in advance in the ROM or the storage device. Is determined to receive INVITE after the detail generation device 20 (No in step S102). Further, when the identification information adding unit 100 determines that the received SIP message is not 200 OK (No in step S112), the INVITE generated based on the received INVITE is transmitted to the called communication terminal by a normal procedure. (Step S118).

Next, when receiving the INVITE from the relay device 10C, the mobile communication terminal 50 transmits 200 OK to the relay device 10C as a response to the received INVITE (step S410).
Next, when the relay device 10C receives 200OK from the mobile communication terminal 50, the relay device 10C generates 200OK (3) in which the IP address (3) of the own device 10C is added to the header portion of the received 200OK. Then, the generated 200 OK (3) is transmitted to the detail generation device 20 (step S412).

  Specifically, when the identification information adding unit 100 receives the SIP message (200 OK) from the mobile communication terminal 50 (Yes in step S100), the relay device 10C uses the reception order information stored in advance in the ROM or the storage device. It is determined that the own device 10C receives INVITE after the detail generation device 20 (No in step S102). Further, when the identification information adding unit 100 determines that the received SIP message is 200 OK (Yes in step S112), the IP address of the own device 10C is added to the received 200 OK header (step S114). The identification information adding unit 100 adds only the IP address (3) of its own device 10C to the header part because the relay device 10C receives 200 OK from the called mobile communication terminal 50 prior to other relay devices. To do. The relay device 10C transmits the generated 200 OK (3) in the SIP message transmission unit 102 to the detail generation device 20 (step S116).

Next, when receiving the 200 OK (3) from the relay device 10C, the detail generation device 20 transmits the 200 OK generated based on the received 200 OK (3) to the relay device 10B. On the other hand, billing details information (CDR) is generated based on the received INVITE (1) (2) and 200 OK (3) (S414).
Specifically, when the billing detail information generating unit 200 determines that the billing detail information generating unit 200 has received INVITE (1) (2) and 200OK (3) corresponding to the INVITE (1) (2) (step S200). OK), the IP addresses (1), (2), and (3) are extracted from the header part of these received SIP messages (step S202). Further, in the billing details information generation unit 200, billing details information (hereinafter, billing details information (1) including the extracted IP addresses (1), (2) and (3) and the IP address (4) of the own device 20). -4)) is generated (step S204). Then, the billing detail information generating unit 200 stores the generated billing detail information (1-4) in the RAM or the storage device (step S206).

Further, when receiving the 200 OK from the detail generation device 20, the relay device 10B transmits the 200 OK generated based on the received 200 OK to the relay device 10A (step S416).
Specifically, when the identification information adding unit 100 determines that the relay message 10B has received the SIP message (200 OK) (Yes in step S100), the relay device 10B uses the reception order information stored in advance in the ROM or the storage device 10B. Is determined to receive INVITE before the detail generation device 20 (Yes in step S102). Further, when the identification information adding unit 100 determines that the received SIP message is not INVITE (No in step S104), the 200OK generated based on the received 200OK is transmitted to the called communication terminal in a normal procedure. (Step S110).

Next, when the relay device 10A receives 200OK from the relay device 10B, the relay device 10A transmits the 200OK generated based on the received 200OK to the mobile communication terminal 40 on the calling side (step S418). Since the specific operation is the same as that of the relay device 10B, description thereof is omitted.
Thereby, 200 OK is received in the mobile communication terminal 40, a call is established between the mobile communication terminal 40 and the mobile communication terminal 50, and a call is started.

After that, as shown in FIG. 12, it is assumed that a failure accompanying call disconnection occurs in the relay device 10B, and a restart process occurs. Thereby, the relay device 10B transmits the failure notification information to the non-billing processing device 30 (step S420).
Specifically, when the failure notification information transmission unit 104 determines that the restart process has occurred (Yes in step S150), the relay device 10B has a failure including the identification information of the own device 10B (here, the IP address (2)). Notification information (hereinafter referred to as failure notification information (2)) is generated (step S152). Then, the generated failure notification information (2) is transmitted to the non-billing processing apparatus 30 via a transmission path different from the preset communication path.

On the other hand, when the call is disconnected due to the occurrence of the restart process, the billing details information is transmitted from the detail generation device 20 to the non-billing processing device 30 as shown in FIG. 12 (step S422).
Specifically, when the billing details information transmission unit 202 detects disconnection of the call (Yes in step S250), the billing details information transmission unit 202 retrieves the billing details information including the billing details information (1-4) from the RAM or the storage device. Read (step S252). Then, the read billing detail information is transmitted to the non-billing processing device 30 (step S254).

If the non-billing processing device 30 determines that the detailed billing information is received from the detail generation device 20 in the detail information receiving unit 300, the received billing detail information is stored in the RAM or the storage device.
If the non-billing processing device 30 determines that the failure information is received from the relay device 10B in the detail information extraction unit 302 (Yes in step S300), the unprocessed billing details stored in the RAM or the storage device. Information is read (step S302). The detailed information extraction unit 302 compares the IP address included in the read billing detailed information with the IP address (2) that is the failed device identification information included in the failure notification information (2) (step S304). The detail information extraction unit 302 determines whether or not the IP address (2) is included based on the comparison result (step S306).

Specifically, it is assumed that the billing details information (1-4) is read in the details information extraction unit 302 (S302). The detail information extraction unit 302 includes the IP address (1), (2), (3), (4) included in the read billing detail information (1-4) and the IP address included in the failure notification information (2). (2) is compared (step S304). From this comparison result, the detailed information extracting unit 302 determines that the IP address (2) is included in the charging detailed information (1-4) (Yes in step S306). As a result, the detailed information extraction unit 302 sets the charging detailed information (1-4) to the non-billing target CDR (step S308), and outputs the non-billing target CDR to the non-billing processing unit 304 (step S310).
The comparison process and the determination process are repeatedly executed until there is no unprocessed billing detail information from the RAM or the storage device.

(4) Operation and Effect In the non-billing processing system 1 according to the above-described embodiment, the control information is relayed to the control information (for example, SIP message) relayed to the detail generation device 20 in each relay device 10. The identification information of the own device 10 can be added to the identification information (for example, IP address, etc.) of all the other relay devices 10 up to the own device 10 included in. Further, in each relay device 10, failure notification information including identification information of the own device 10 is transmitted to the non-billing processing device 30 at the time of recovery processing (restart processing) from the failure that accompanies disconnection of the call that occurred in the own device 10. can do.

  On the other hand, based on the control information from the relay device 10, the detail generation device 20 can generate billing detail information including identification information of all the relay devices that have relayed the control information to the own device 20. Further, the detail generation device 20 stores and holds the generated billing detail information, and when detecting disconnection of a call due to a failure that has occurred in the relay device 10, transmits the billing detail information stored and retained to the non-billing processing device 30. be able to.

  Further, when the non-billing processing device 30 stores and holds the billing details information received from the detail generation device 20 and determines that the failure notification information from the relay device 10 in which the failure has occurred is received, the non-billing processing device 30 stores the billing details information stored and retained. read out. Then, the identification information of the relay device 10 included in the read billing specification information is compared with the identification information (failed device identification information) of the faulty relay device included in the fault notification information. The billing details information including the faulty device identification information can be extracted. The non-billing processing device 30 sets the extracted billing detail information in the non-billing target CDR, and deletes the non-billing target CDR so that the detailed bill is not generated for the non-billing target CDR. Charges for all or part of the communication time from the establishment of the corresponding call to the completion of the restart process (recovery from the failure) can be made uncharged.

As described above, it is possible to obtain an effect that it is possible to surely eliminate the charge for all or part of the communication time from the establishment of the call to the completion of the recovery process of the relay apparatus 10 in which the failure has occurred.
Communication from the establishment of a call to the completion of the recovery process of the failed relay device 10 with a simple system configuration without interlocking control of transmission / reception of control information between each relay device 10 and the detail generation device 20 There is an effect that the charge for all or part of the time can be surely not charged.

Also, each relay device 10 can transmit the failure notification information to the non-billing processing device 30 via a transmission path different from the preset communication path.
As a result, even when a double failure or the like occurs in the communication path, the charge for all or part of the communication time from the establishment of the call to the completion of the recovery processing of the relay device 10 in which the failure has occurred is surely not charged. The effect that it can do is acquired.
