It can be transmitted to In the first embodiment, a maintenance manager who manages the device group 18 of the core network 20 transmits a command using the SMS of the mobile phone 12, that is, transmits a short message including the command. ing. More detailed transmission contents will be described later.

  The base station 14 forms a communication area for mobile devices such as the mobile phone 12 and a portable personal computer. The base station 14 relays voice data, communication data, and the like received from the mobile phone 12 to the core network 20 via the public line 16. This base station 14 may be either a macro base station or a femtocell base station that communicates with a mobile phone. In addition, when the base station 14 is a femtocell base station, a router, a modem, etc. are installed between the base station 14 and the public line 16.

  The public line 16 is an open line shared and used by an unspecified number of users, and includes a telephone line that is not a closed dedicated line, radio, the Internet, and the like. For example, when the base station 14 is a macro base station, the public line 16 includes xDSL (Digital Subscriber Line), a coaxial cable, wired or wireless such as an optical fiber, etc. For example, when the base station 14 is a femtocell base station, Including the Internet.

  A control station 24 and a gateway are connected between the public line 16 and the core network 20.

  The control station 24 connects a plurality of base stations including the base station 14. The control station 24 controls a plurality of base stations including the base station 14 via the public line 16. For example, the control station 24 performs connection control of the mobile phone 12 via the base station 14. Further, the control station 24 is connected to the core network 20 via the gateway 26.

  The gateway 26 restricts access from the public line 16 via the control station 24 to the core network 20. The gateway 26 may have functions such as a proxy server and a firewall.

  The core network 20 is a dedicated line of a communication carrier that connects CSCFs (Call Session Control Functions) indicating servers functioning as an exchange, and is a network based on a standard for realizing multimedia services and the like: IMS (IP Multimedia Subsystem) It is.

  The core network 20 has at least one device. In the first embodiment, the core network 20 includes, for example, a CSCF group including the first CSCF 28, the second CSCF 30, and the third CSCF 32, and a general short message service center (hereinafter referred to as a short message service) that provides a short message service different from electronic mail. The service center is referred to as “SMSC” (Short Message Service Center).) 34 and the center group including the maintenance management SMSC 36, and other server groups including the first server 38, the second server 40, and the third server 42. It is constructed by the device group 18 having. In the first embodiment, it is assumed that the monitoring server 22 is arranged in the core network 20 but is not included in the device group 18.

Each CSCF including the first CSCF 28 connected to the gateway 26 in FIG. 1 is a SIP (Session Initiation Protocol) server having a function as an exchange, and controls a voice call between mobile phones on the public line 16. Each CSCF receives a voice call connection request from a mobile phone 12 located in the base station 14 with a mobile phone located in a base station (not shown) different from the base station 14 as a connection destination, for example. In this case, the connection request is transmitted to a base station (not shown) via the gateway 26. Each CSCF controls various other server groups including the first server 38 to provide various information to the transmitting side (calling side) mobile phone 12 and the receiving side (calling side) mobile phone (not shown). Send.
Each CSCF is connected to a general SMSC 34 as a first short message service center and a maintenance management SMSC 36 as a second short message service center. Based on the received first center identification information (for example, a 4-digit center number starting from “0”), the information is transferred to the general SMSC 34 or the maintenance management dedicated SMSC 36.

  The general SMSC 34 is composed of a plurality of servers, for example, for relaying a short message between mobile phones including the mobile phone 12, and provides a short message service (SMS) for general users. . Specifically, the general SMSC 34 receives a short message having a size limit (for example, 140 bytes) from the mobile phone 12 on the calling side based on the telephone number as identification information of the mobile phone on the receiving side of the short message, Send to the receiving mobile phone. The general SMSC 34 can also transmit a short message simultaneously to a plurality of mobile phones in a broadcast format.

  The dedicated maintenance management SMSC 36 provides a remote monitoring service for maintenance managers. Unlike the general SMSC 34, the maintenance management dedicated SMSC 36 is configured exclusively for transferring a short message including a command from the mobile phone 12 or the like to the monitoring server 22, for example, by a plurality of servers. The maintenance management SMSC 36 receives the second center identification information (for example, a telephone number starting with “090”) of the maintenance management SMSC 36 together with the short message, and issues a command when the authentication of the second center identification information is obtained. The short message including it is transferred to the monitoring server 22.

  The servers such as the first server 38, the second server 40, and the third server 42 in the server group are not limited, and examples include a service control device (SCP) and a number registration device (FNR). The service control device (SCP) has a database in which the telephone number of the main line and the telephone number of the sub line used in each mobile phone are stored in association with each other, and can use the main line and the sub line. Executes various processes required when providing services. This service control device (SCP) also has a dedicated HLR (Home Location Register) function used in the above-described multi-line service. In addition, the number registration device (FNR) registers the telephone number of the main line and the telephone number of the secondary line used in each mobile phone in association with each other, and uses the telephone number used in the old generation communication method to generate a new generation. A process for enabling the use of communication-type telephone communication is executed.

  The monitoring server 22 is configured to monitor the device group 18 that constructs the core network 20 and allow the maintenance manager to check the result on a display screen or the like. For example, the monitoring server 22 automatically monitors the device group 18 every 10 minutes to monitor information of the device group 18 such as a CPU operation rate, an error rate, and a customer accommodation rate, and records a history of the monitored information. Stored on a storage medium.

<Action>
Next, the operation of the remote monitoring system 10 according to the first embodiment of the present invention will be described. FIG. 3 is a diagram showing a flowchart of processing of the entire remote monitoring system 10 according to the first embodiment of the present invention. Hereinafter, the identification code in parentheses corresponds to the step identification code in FIG.

(SP10) The maintenance manager wants to remotely monitor the device group 18 at a location remote from the monitoring server 22, for example, when going out, in the event of an emergency when a communication failure has occurred or when a communication failure is predicted. You may want to check. In such a case, the maintenance manager uses the short message software of the mobile phone 12 to send a short message including commands as shown in FIGS. 4A to 4C to the maintenance management dedicated SMSC 36, for example. . This command is sent to the maintenance manager by using the normal touch panel 12B, for example, as shown in command A in FIG. 4A, for example, “monitored device name (eg“ Switchboard1 ”) + view + monitoring location (eg“ absorption ”). A person enters a command in a computer language created for instructing a computer to instruct a command such as "rate") ". The command A shown in FIG. 4A is a monitoring command for monitoring the current customer capacity of the first CSCF 28. The command B shown in FIG. 4B is a monitoring command for monitoring the error rate of connection failure occurring in the first CSCF 28. A command C shown in FIG. 4C is a monitoring command for monitoring the CPU operating rate of the first server 38. Note that the commands shown in FIGS. 4A to 4C are examples, and various command contents and command expression methods can be adopted.

  At this time, the mobile phone 12 transmits, together with a short message, for example, a 4-digit maintenance management SMSC 36 center number starting from “0” and a maintenance management SMSC 36 telephone number starting from “090”, for example. (Hereinafter, all information transmitted from the mobile phone 12 when a short message is transmitted is referred to as “short message etc.”). The short message or the like from the mobile phone 12 reaches the exchange, for example, the first CSCF 28 via the base station 14, the public line 16, the control station 24, and the gateway 26.

(SP12) When the first CSCF 28 receives a short message or the like from the mobile phone 12, the first CSCF 28 refers to a storage table (not shown) in which the center number and the short message center are associated with each other to determine which center number is included in the short message or the like. It is determined whether the short message center is indicated. When the first CSCF 28 determines that the center number indicates the maintenance management dedicated SMSC 36, the first CSCF 28 transfers a short message or the like to the maintenance management dedicated SMSC 36. When the first CSCF 28 determines that the center number indicates the maintenance management dedicated SMSC 36, the first CSCF 28 transfers a short message or the like to the maintenance management dedicated SMSC 36.

(SP14) When the SMSC 36 for maintenance management receives a short message or the like from the first CSCF 28, whether or not the telephone number included in the short message is the telephone number of the SMSC 36 for maintenance management, that is, the telephone number included in the short message or the like. Determine if is correct. If the maintenance management SMSC 36 determines that it is correct, that is, if the telephone number is authenticated, it transfers a short message or the like to the monitoring server 22, and if it is determined that it is not correct, that is, the telephone number is authenticated. If not, error information is transmitted to the mobile phone 12, for example, although not shown.

(SP16, SP18, SP20, SP22) Upon receiving a short message or the like from the maintenance management dedicated SMSC 36, the monitoring server 22 executes a command included in the short message or the like. In the first embodiment, the monitoring server 22 determines whether the command included in the received short message or the like is a monitoring command for monitoring information on at least one device in the device group 18 before executing the command. (Hereinafter, the device information is referred to as “monitoring information”). If the affirmative determination is made, the monitoring server 22 executes a command to monitor (acquire) the monitoring information, and transmits a short message including the monitoring information to the maintenance management SMSC 36. If the monitoring server 22 makes a negative determination, for example, if the received command is an operation command for remotely operating at least one device in the device group 18, execution of the command is prohibited.

  Note that the monitoring information is acquired by using at least one device (monitoring target device) in the device group 18 for which the monitoring server 22 wants to obtain information when executing the command, as in steps SP18 and SP20 of FIG. The monitoring information may be acquired and transmitted to the monitoring server 22, or all or part of the history of monitoring information already stored in the monitoring server 22 (for example, the latest information) may be acquired.

(SP24) When the SMSC 36 for maintenance management obtains the short message including the monitoring information from the monitoring server 22, it transfers it to the CSCF such as the first CSCF 28.

(SP26) When the CSCF such as the first CSCF 28 acquires the short message including the monitoring information from the maintenance management dedicated SMSC 36, it transfers it to the mobile phone 12.

(SP28) When the short message software of the mobile phone 12 receives the short message including the monitoring information from the first CSCF 28, the short message software notifies the user of the mobile phone 12, that is, the maintenance manager of the reception. When a short message is opened by the maintenance manager who has received the notification, a short message including monitoring information is displayed on the touch panel 12B. This display content is monitoring information corresponding to the commands shown in FIGS. 4A to 4C, for example, as shown in FIGS. The display contents may be displayed in a computer language as in the commands shown in FIGS. 4A to 4C, or may be displayed in a natural language such as Japanese or English.

  As described above, according to the remote monitoring system 10 according to the first embodiment of the present invention, the maintenance manager transmits the short message including the command from the mobile phone 12 to the SMSC 36 for maintenance management, so that the monitoring server 22 The device information is monitored by executing the command, and the information is displayed on the mobile phone 12. Therefore, according to the remote monitoring system 10, it is possible to remotely monitor the device group 18 even when the maintenance manager is at a location remote from the monitoring server 22.

  Further, since SMS is used to transmit a command from the mobile phone 12, it is not necessary to install special application software or a device for transmitting the command in the mobile phone 12.

  The short message center has a dedicated maintenance management SMSC 36 for transferring commands separately from the general SMSC 34. Then, the exchange such as the first CSCF 28 transfers the short message received from the mobile phone 12 to the general SMSC 34 or the maintenance management dedicated SMSC 36 based on the center number received together with the short message. For this reason, when the user of the mobile phone 12 transmits a short message including a command, the user needs to know the center number of the maintenance management dedicated SMSC 36 or to register the center number in the mobile phone 12 in advance. . Therefore, it is possible to suppress a user other than the maintenance manager from sending a short message including a command illegally, thereby improving the security of the remote monitoring system 10.

  Further, not only the exchange such as the first CSCF 28 but also the maintenance management SMSC 36 receives the telephone number addressed to the maintenance management SMSC 36 together with the short message, and transfers the command to the monitoring server 22 when the telephone number is authenticated. ing. For this reason, when the user of the mobile phone 12 transmits a short message including a command, the user needs to know the phone number of the maintenance management dedicated SMSC 36 or the phone number must be registered in the mobile phone 12 in advance. . Therefore, it is possible to suppress a user other than the maintenance manager from sending a short message including a command illegally, thereby improving the security of the remote monitoring system 10.

  Further, when the received command is an operation command for remotely operating at least one device in the device group, the monitoring server 22 prohibits execution of the operation command. Since this operation command enables remote operation of the device group 18 such as restart of the device group 18, the operation command has a larger influence on the core network 20 than the monitoring command. Therefore, when the device group 18 is remotely operated, it is preferable to use a system in which the core network 20 and the monitoring server 22 are connected by a dedicated line, which has higher security than the remote monitoring system 10. In the first embodiment, the security of the remote monitoring system 10 can be enhanced by suppressing the influence on the core network 20 by remote operation. However, if the remote monitoring system 10 has high security, the monitoring server 22 may execute an operation command.

(Second Embodiment)
Next, a remote monitoring system will be described as an example of a remote communication system according to the second embodiment of the present invention. In the first embodiment, the maintenance management SMSC 36 authenticates the telephone number addressed to the maintenance management SMSC 36. In the third embodiment, in addition to this authentication, the sender's mobile phone 12 is authenticated. This is different from the first embodiment.

  The remote monitoring system according to the second embodiment of the present invention has the same configuration as that of the first embodiment. The operation of the remote monitoring system according to the second embodiment of the present invention is the same as that of the first embodiment except for the following operations.

  FIG. 6 is a view showing a flowchart of processing of the maintenance management dedicated SMSC 36 in the remote monitoring system according to the second embodiment of the present invention. Hereinafter, the identification codes in parentheses correspond to the step identification codes in FIG. This process is started when a short message or the like is received from an exchange such as the first CSCF 28, for example.

(SP30) The maintenance management dedicated SMSC 36 refers to the telephone number addressed to the maintenance management dedicated SMSC 36 included in the short message or the like. Next, the maintenance management dedicated SMSC 36 determines whether this telephone number is the telephone number of the maintenance management dedicated SMSC 36 itself, that is, whether the telephone number addressed to the maintenance management dedicated SMSC 36 included in the short message or the like is correct. The judgment is made with reference to a database (not shown) in which the telephone number of the management-dedicated SMSC 36 is registered. When the maintenance management dedicated SMSC 36 determines that it is correct (Yes), it proceeds to the process of step SP32. When it determines that it is not correct (No), it proceeds to the process of step SP36.

(SP32) The maintenance management dedicated SMSC 36 refers to the telephone number of the sender's mobile phone 12 included in the short message or the like. Next, the maintenance management dedicated SMSC 36 refers to a registration table (not shown) in which the telephone number of the mobile phone 12 possessed by the maintenance manager is registered, and determines whether or not the telephone number of the mobile phone 12 is registered. If the maintenance management dedicated SMSC 36 determines that it is registered (Yes), that is, if the mobile phone 12 is authenticated, the process proceeds to step SP34, and if it is determined that it is not registered (No) ), That is, if the mobile phone 12 cannot be authenticated, the process proceeds to step SP36.

(SP34) The maintenance management dedicated SMSC 36 transfers a short message or the like to the monitoring server 22 and ends the series of processing.

(SP36) The maintenance management-dedicated SMSC 36 discards, for example, a short message, transmits error information to the mobile phone 12, and ends the series of processing.

  As described above, according to the remote monitoring system of the second embodiment of the present invention, the maintenance management SMSC 36 not only authenticates the telephone number of the maintenance management SMSC 36 but also the mobile phone in order to transfer a short message or the like. Since twelve telephone numbers are authenticated, the security of the remote monitoring system 10 can be further enhanced.
