(Embodiment)
A communication system according to an embodiment of the present invention will be described with reference to FIG. The communication system according to the embodiment of the present invention includes an SSE (Subscriber Service Edge) 3, an SSC (Subscriber Session Control server) 4, an operation center device 5, and a terminal device 6. The SSE 3 and the terminal device 6 are connected to each other by the access network 2. The SSE 3 is connected to the core network 1.

  The core network 1 is a transfer network connected by a large-capacity router. The terminal device 6 may be connected to other terminal devices via the SSE 3 and the core network 1.

  The access network 2 is a transfer network. The access network 2 includes a transmission device and a VDSL device for distributing the optical fiber to the user's home.

  The SSE 3 is an edge router that transmits and receives packets to and from the terminal device 6. The SSE 3 is connected to the core network 1 and the access network 2 and is also connected to the SSC 4. SSE3 processes the service order data input from SSC4, and notifies SSC4 of the service status of SSE3. The service state is a state of either INS (IN Service) or OUS (Out of Service). The SSC 4 notifies the service state of the SSE 3 to the SSC 4 by a monitoring function such as a TCP / IP KeepAlive function or SNMP (Simple Network Management Protocol).

  In FIG. 1, a first SSE 3a and a second SSE 3b are described as SSE3. Hereinafter, when it is not specified which SSE, it is simply described as “SSE3”.

  The SSC 4 is a server device including a subscriber session control function which is a feature according to the embodiment of the present invention. SSC4 houses SSE3a and SSE3b. The SSC 4 receives the service order data from the operation center device 5 and distributes it to the SSE that is the target of the service order.

The operation center device 5 is a device arranged at a center in charge of system maintenance and operation. The operation center device 5 is connected to the SSC 4 and inputs service order data distributed to the SSE 3 to the SSC 4 .
The terminal device 6 is a communication terminal used in the subscriber's home. The terminal device 6 can be connected to a public communication network via the access network 2 and the SSE 3.

  The SSE3, SSC4, the operation center device 5, the terminal device 6 and the like are realized by installing a program for executing a predetermined process in a general computer. Each of SSE3, SSC4, operation center device 5, terminal device 6 and the like may be constituted by a plurality of computers, or may be mounted on an existing communication device or the like.

In the communication system according to the embodiment of the present invention, when there is a communication apparatus that is not in service (OUS state) among communication apparatuses that are involved in SO processing, the in-service state that is positioned above the OUS state apparatus The control server in the (INS state) stores that the SO related to the communication device in the OUS state and the SO processing of the device in the OUS state are unprocessed. Further control server in the INS state, monitors the state of the communication device OUS state, when it is detected that consisted OUS state in INS state immediately the process of SO.

  Here, the “communication device related to SO processing” is SSE3 in the example of FIG. In the example of FIG. 1, “the control server in the INS state positioned above the device in the OUS state” is SSC4. Here, the device positioned “upper” means a device closer to the operation center device 5 than the “communication device related to SO processing”, for example, a device to which the SO of the operation center device 5 is sent. .

  In the communication system according to the embodiment of the present invention, when the operation center device 5 transmits SO data, the SSC 4 stores the SO data. The SO data is, for example, data of new contractors of the terminal devices 6a and 6b connected to the SSE 3a and SSE 3b. The SSC 4 tries to set the SIP port of the new contractor for the SSE 3a and SSE 3b based on the accumulated SO data. Here, for example, when the SSE 3a is in the OUS state, the SSC 4 cannot set the SIP port, and accumulates that the SIP port setting of the new contractor of the SSE 3a is not set. When the SSC 4 monitors the state of the SSE 3a and detects that the state has changed from the OUS state to the INS state, the SSC 4 immediately sets the SIP port of the new contractor that could not be set.

  Next, SSC 4 and SSE 3 according to the embodiment of the present invention will be described in detail with reference to FIG. In FIG. 2, only the part which concerns on the characteristic of this invention is described notionally among SSC4 and SSE3 which concern on embodiment of this invention.

  The first SSE 3a includes a service status transmission unit 31a and a service order reception unit 32a.

  The service status transmission unit 31a transmits the service status of the first SSE 3a to the SSC 4. The service status transmission unit 31a may actively transmit the service status, or may transmit the service status in a format in response to an inquiry from the SSC 4. In addition, the service status transmission unit 31a responds to the inquiry from the SSC 4 only in the INS state, so that the SSC 4 can inform the SSC 4 that there is a response and the OUS state if there is no response. good. Specifically, the service state transmitting unit 31a notifies the SSC 4 of the service state of the first SSE 3a by a keep-alive function such as H.248 (Megaco) or a monitoring function such as SNMP (Simple Network Management Protocol). good.

  The service order receiving unit 32a receives the SO data transmitted from the SSC 4. The first SSE 3a makes various settings based on the SO data received by the service order receiving unit 32a, and returns the result to the SSC 4.

  The second SSE 3b also has the same configuration as the first SSE 3a.

  The SSC 4 includes a SIP signal control unit 41, a subscriber information management unit 42, a SIP port management control unit 43, an SSE state management unit 44, an SSE control unit 45, an unset port information storage unit 46, a subscriber information storage unit 47, and an SSE. A state storage unit 48 is provided. The SIP signal control unit 41, the subscriber information management unit 42, the SIP port management control unit 43, the SSE state management unit 44, and the SSE control unit 45 are configured to control the central processing of the SSC 4 by installing a predetermined control program in the SSC 4. Implemented in the device. Further, the storage device of the SSC 4 includes an unset port information storage unit 46, a subscriber information storage unit 47, and an SSE state storage unit 48.

  The SIP signal control unit 41 receives the SIP message, processes it based on the received signal, and returns it. The SIP signal control unit 41 receives, for example, INVITE, 200 OK, etc., processes the received signal, and transmits INVITE, 200 OK, etc. based on the processed result.

At this time, when receiving the SIP message, the SIP signal control unit 41 inputs the information of the transmission destination to the SIP port management control unit 43. The SIP port management control unit 43 searches the unset port information storage unit 46 to determine whether or not a port is set for the transmission destination input from the SIP signal control unit 41, and uses the result as the SIP signal control. Input to the unit 41. When the SIP signal control unit 41 receives a result indicating that the destination port is set from the SIP port management control unit 43, the SIP signal control unit 41 directly processes and returns the result based on the received signal. On the other hand, when receiving a result indicating that the destination port is not set, the SIP signal control unit 41 transmits an error message to the transmission source of the SIP message.

  For example, when the SIP signal control unit 41 receives an INVITE message from a UAC (User Agent Client), a UAS (User Agent Server) that is a terminal to which the INVITE message is transmitted is registered in the unconfigured port information storage unit 46. If so, send an error message.

  The subscriber information management unit 42 stores the SO data input from the operation center device 5 in the subscriber information storage unit 47. The subscriber information management unit 24 receives and accumulates SO data transmitted from the operation center device 5. The subscriber information management unit 24 notifies the SIP port management control unit 43 that the SO data has been accumulated, and is also notified from the SIP port management control unit 43. The acquired IP address and port number according to the SIP port setting. Accumulate.

  In the subscriber information storage unit 47, subscriber information data 47a is stored. As shown in FIG. 3, the subscriber information data 47a is data in which a user ID is associated with session information assigned to the user. The session information includes an IP address, a port number, a session priority, a direction attribute, a bandwidth, and the like.

  The SIP port management control unit 43 obtains the service state of the SSE 3 that is the SO data distribution destination from the SSE state storage unit 48, and distributes the service order data to the SSE 3 when the service state is the INS state. The SIP port management control unit 43 further stores the SO data in the unset port information storage unit 46 when the service state is the OUS state.

  A case will be described in which the subscriber information management unit 42 accumulates SO data related to data of a new contractor connected to the SSE 3a and / or SSE 3b in the subscriber information accumulation unit 47. When the SIP port management control unit 43 is notified by the subscriber information management unit 42 that the SO data has been accumulated, if the SSE 3a and SSE 3b are in the INS state, the SIP port management control unit 43 sends a command for setting the SIP port to the SSE control unit 45. The IP address and the port number transmitted from the SSE control unit 45 are notified to the subscriber information management unit 42. When the IP address and the port number are notified from the SIP port management control unit 43, the subscriber information management unit 42 stores the information in the subscriber information storage unit 47 in association with the user ID. Thereby, the SIP signal transmitted from the terminal device 6 of the new contractor can pass through the SSE 3a or SSE 3b.

  Further, the SIP port management control unit 43, when the SSE 3a and / or the SSE 3b cannot set the SIP port because the SSE 3a and / or the SSE 3b are in the OUS state, stores information on the new contractor who could not set the SIP port, 46. When the SSE state management unit 44 notifies that the state of the SSE 3a and / or SSE 3b has changed from the OUS state to the INS state, the SIP port management control unit 43 sets the SIP port that can be set for the new subscriber. The information is taken out from the unset port information storage unit 46 and input to the SSE control unit 45, which causes the SSE control unit 45 to set the SIP port.

  When the service state of the SSE 3 changes from the OUS state to the INS state, the SIP port management control unit 43 receives a notification from the SSE state management unit 44. At this time, the SIP port management control unit 43 extracts the SO data of the SSE 3 whose service state has changed from the OUS state to the INS state from the unconfigured port information storage unit 46 and transmits the SO data to the SSE 3. At that time, the SIP port management control unit 43 deletes the processed data regarding the SO from the unset port information storage unit 47.

  When the SIP signal control unit 41 receives a call from another communication device to the terminal device of the subscriber accommodated in the SSE 3 connected to the SSC 4, the information on the terminal device of the destination subscriber is received by the SIP port. Input to the management control unit 43. The call is, for example, an INVITE message. The SIP port management control unit 43 acquires information about the communication device that is the destination of the INVITE message. The SIP port management control unit 43 searches the unset port information storage unit 46 for information on whether or not this destination communication device is included, and inputs the result to the SIP signal control unit 41.

  For example, when registered in the unset port information storage unit 46, specifically, when the port of the UAS that is the destination communication device is not set, the SIP signal control unit 41 sends an error message to the UAC. To do. On the other hand, when the port is not registered in the unset port information storage unit 46, specifically, when the port of the UAS that is the destination communication device is set, the SIP signal control unit 41 sends the INVITE message to the UAS. Forward to.

  The SSE state management unit 44 receives the service states of the communication devices such as the first SSE 3a and the second SSE 3b, associates the identifier of the communication device with the service state of the communication device, and stores it in the SSE state storage unit 48. Remember. The SSE state management unit 44 uses the first SSE 3a, the second SSE 3b, and the like, for example, a keep-alive function such as H.248 (Megaco), a monitoring function such as SNMP (Simple Network Management Protocol), etc. The state is acquired and stored in the SSE state storage unit 48.

  The SSE state accumulation unit 48 stores SSE state data 48a. As shown in FIG. 4, the SSE status data 48a associates an SSE identifier with its service status. The service state is an INS state, an OUS state, or the like. The service state is constantly updated by the SSE state management unit 44. The SSE status data 48a shown in FIG. 4 stores only the latest service status.

  When there is an inquiry about the service state of SSE3 from the SIP port management control unit 43, the SSE state management unit 44 refers to the SSE state storage unit 48 and obtains the service state associated with the identifier of the SSE that made the inquiry. Then, it returns to the SIP port management control unit 43.

  Further, when there is an SSE whose service state has changed from the OUS state to the INS state, the SSE state management unit 44 notifies the SIP port management control unit 43 of information such as the identifier of the SSE. The SIP port management control unit 43 refers to the unset port information storage unit 46 and searches for information on the notified SSE. When there is information, the SIP port management control unit 43 transmits SO to the SSE via the SSE control unit 45.

  When notified from the SIP port management control unit 43 to set the SIP port, the SSE control unit 45 sets the SIP port to the SSE 3a and / or the SSE 3b. Further, the SSE control unit 45 notifies the SIP port management control unit 43 of the IP address and port number acquired in accordance with the setting.

  Next, processing of the SIP port management control unit 43 according to the embodiment of the present invention will be described with reference to FIGS.

  With reference to FIG. 5, the processing of SO input from the operation center apparatus 5 will be described.

  First, in step S <b> 101, the subscriber information management unit 42 receives the SO transmitted from the operation center 5 and accumulates the information in the subscriber information accumulation unit 47. Further, the subscriber information management unit 42 notifies the SIP port management control unit 43 of the accumulation. Here, SO is, for example, data of a new contractor connected to the first SSE 3a and / or the second SSE 3b. In step S102, the SIP port management control unit 43 inquires of the SSE state management unit 44 and acquires the states of the first SSE 3a and the second SSE 3b in the SSE state storage unit 48. Here, when the state of the first SSE 3 a and the second SSE 3 b is the INS state, the SIP port management control unit 43 notifies the SSE control unit 45 to set the SIP port. In step S103, the SSE control unit 45 tries to set the SIP port to the first SSE 3a and / or the second SSE 3b.

  In step S104, it is determined whether or not the SIP port setting has been normally completed. If the SIP port setting is successful, in step S105, the SSE control unit 45 acquires the IP address and port number from the first SSE 3a and / or the second SSE 3b, and the acquired IP address and port number are used as the SIP port. Tell the management control unit 43. The SIP port management control unit 43 receives the IP address and port number, and notifies the subscriber information storage unit 42 of the received IP address and port number. In step S 106, the subscriber information storage unit 42 stores the received IP address and port number in the subscriber information storage unit 47.

  On the other hand, if it is determined in step S104 that the SIP port setting in step S103 did not end normally, the process proceeds to step S107. For example, after the INS state is detected in step S102, the state transitions from the INS state to the OUS state, and if the SIP port cannot be set in step S103, the process proceeds to step S107.

  In step S102, if the SIP port management control unit 43 cannot set the SIP port because the first SSE 3a and / or the second SSE 3b are in the OUS state, the process proceeds to step S107.

  In step S <b> 107, the SIP port management control unit 43 performs control so that information on a new contractor who has not been able to set a SIP port is stored in the unset port information storage unit 46.

  Further, in step S108, the SSE state management unit 44 receives the state transmitted from the first SSE 3a and the second SSE 3b. Here, when the SSE state management unit 44 detects that the state of the first SSE 3a and / or the second SSE 3b has changed from the OUS state to the INS state in step S109, it notifies the SIP port management control unit 43. In step S110, the SIP port management control unit 43 controls the unset port information storage unit 46 to extract information on a new contractor who can set the SIP port, and the process proceeds to step S103. In steps S103 to S106, as described above, the SSE control unit 45 sets the SIP port setting, acquires the address and port number, and the subscriber information management unit 42 stores in the subscriber information storage unit 47. accumulate.

  With reference to FIG. 6, the processing of a call when input from the SIP signal control unit 41 will be described.

  First, when the SIP signal control unit 41 receives a SIP message call in step S201, it is determined in step S202 whether or not the call type is an INVITE message. If it is not an INVITE message, the call is processed as usual in step S203 and the process is terminated.

  On the other hand, if it is determined in step S202 that the call type is an INVITE message, the SIP signal control unit 41 inputs information on the transmission destination of the call to the SIP port management control unit 43 in step S204. The SIP port management control unit 43 determines whether there is information on the transmission destination of the call in the unset port information storage unit 46 and transmits the result to the SIP signal control unit 41.

  In step S204, if the call destination information is not stored in the unset port information storage unit 46, the SIP signal control unit 41 has already been set for the call destination because the SIP port, IP address, port number, and the like are already set. Returns 200OK in step S206. On the other hand, if there is registration in step S204, an error message is returned because the SIP port, IP address, port number, etc. have not been set for the destination of the call.

  Next, processing of the communication system shown in FIG. 1 will be described with reference to FIG. In FIG. 7, processing for the first SSE 3 a, the second SSE 3 b, SSC 4, and the operation device 5 will be described. Here, the service state of the first SSE 3a is initially in the OUS state and later in the INS state. The service state of the second SSE 3b is the INS state.

  First, in step S301, the first SSE 3a notifies the SSC 4 that the service state is the OUS state, and the SSC 4 associates the fact with the identifier of the first SSE 3a in the SSE state storage unit 48. accumulate. In step S302, the second SSE 3b notifies the SSC 4 that the service state is the INS state, and the SSC 4 stores the fact in the SSE state storage unit 48 in association with the identifier of the second SSE 3b. To do.

  A case where two SOs are input from the operation center device 5 in step S303 after the SSC 4 has accumulated that the first SSE 3a is in the OUS state and the second SSE 3b is in the INS state will be described. Here, one of the SOs is data relating to a new contractor connected to the first SSE 3a, and the other of the SO is data relating to a new contractor connected to the second SSE 3b.

  When two SOs are input from the operations center device 5, the SSC 4 stores the SOs in the subscriber information storage unit 47 in step S304. Further, the SSC 4 processes each SO.

  First, in step S305, the SO for the second SSE 3b is processed. Since the second SSE 3b is in the INS state as notified in step S302, in step S305, the SSC 4 sets a SIP port for the second SSE 3b.

  In steps S306 to S310, the SO for the first SSE 3a is processed. As notified in step S301, since the first SSE 3a is in the OUS state, the SSC 4 stores the SO related to the first SSE 3a received in step S303 in the unset port information storage unit 46. In step S307, the SSC 4 monitors the state of the first SSE 3a. Here, when the first SSE 3a notifies the SSC 4 that the service state is the INS state in step S308, the SSC 4 stores the fact in the SSE state storage unit 48, and in step S309, the first SSE 3a stores the first state. It is detected that the SSE 3a is in the INS state. Thereafter, the SSC 4 processes the SO for the first SSE 3a in step S310. Since the first SSE 3a is in the INS state as detected in step S309, the SSC 4 sets a SIP port for the first SSE 3a in step S310. Thereafter, the SIP port management control unit 43 deletes the data related to the SO from the unset port information storage unit 46.

  As described above, in the communication system according to the embodiment of the present invention, even when the SO input from the operation center apparatus 5 is for the SUS in the OUS state, the information is accumulated and the SSE is in the INS state. When that happens, the SO is processed. Therefore, according to the communication system according to the embodiment of the present invention, it is possible to process the SO after the device is in the INS state even for the device in the OUS state. Regardless of the service state of the SSE, the SO is processed when the operation center device 5 inputs the SO only once, so that the efficiency of the SO input work can be improved.

(Modification)
Next, a modification according to the embodiment of the present invention will be described. In the embodiment of the present invention, the service state is set for each SSE. However, in the modification, a case where the service state can be set for each interface included in the SSE will be described.

  When the first SSE 3a according to the modification has a plurality of interfaces, the first SSE 3a notifies the service state to the SSC 4 for each interface.

  The SSE state management unit 44 according to the modification receives the service state for each SSE and interface, and stores the SSE identifier and interface identifier in association with the service state in the SSE state storage unit 48.

  The SSE state data 48b stored in the SSE state accumulation unit 48 includes an example of data and a data structure as shown in FIG. The SSE status data 48b is associated with a service status using the SSE identifier and the interface identifier as keys.

  The SIP port management control unit 43 acquires the service status of the SO processing target for each SSE identifier and interface identifier. When the SSE and interface to be processed by the SO are in the INS state, the SIP port management control unit 43 immediately processes the SO.

  On the other hand, even if the SSE to be processed by the SO is in the INS state, if the interface of the SSE to be processed is in the OUS state, the SIP port management control unit 43 does not process the SO and sets the unset port information. Accumulate in the accumulation unit 46. When notified that the SSE and interface to be processed are in the INS state, the SIP port management control unit 43 processes the SO.
