The core idea of the present invention will be described in detail with reference to the drawings.

1 is a diagram illustrating the configuration of a remote session management control system according to the present invention. The remote session management control system of the present invention includes a remote management service controller 1200 and a remote management service server 1100. The remote management service server 1100 performs a function of transmitting and receiving information for session management through the wired / wireless network 4000 connected to the remote terminal 2000, and the remote management service server 1100 may be configured as the manager terminal ( 3000 is connected to the wired / wireless network 4000 and performs a session management function of the remote terminal 2000. The remote terminal 2000 transmits / receives information for session management with the remote management service controller 1200 through a wired / wireless network 4000 and performs a session management function in the remote terminal 2000. (2100).

The remote management service server 1100 may include a session management module that performs a session management function, an inventory management module 1120 that performs an inventory management function, and a configuration management module 1130 that performs a configuration management function. , A firmware management module 1140 that performs a firmware management function, a status monitoring module 1150 that performs a function of monitoring a status of the remote terminal 2000, and a task management that manages operations of the remote terminal 2000. It includes any one or more of the module 1160.

The remote management service controller 1200 refers to a physical network node that maintains a management session. Each session node increases the number of sessions to be maintained as the terminal continues to increase, so the physical node is increased to accommodate the required capacity. However, since the administrator must be able to collectively perform management actions in a single location, the session related information is configured to be integrated into the remote management service management server as shown in FIG. 3. The remote management service controller 1200 maintains information on a SIP-based connection session, receives a SIP subscribe message transmitted from a terminal (remote terminal 2000), and stores session information on the terminal. If the access remote terminal 2000 continuously increases, the load for maintaining sessions also increases in parallel, so the remote management service controller 1200 may be expanded in parallel according to the quantity of the receiving remote terminals 2000. .

The remote management service server 1100 is a S / W based equipment is installed and operated on the H / W server equipment equipped with a common commercial OS. It stores manager environment and management information using commercial WEB server and commercial DB server. This S / W corresponds to the manager application for controlling the controller to perform the corresponding management function. The management screen may be changed according to the characteristics and control properties of the remote terminal 2000 to be controlled. Since a plurality of controllers are installed in accordance with the quantity of the receiving remote terminal 2000, this corresponds to the equipment for managing a plurality of controllers in a single location.

The remote management service agent 2100 is a program that creates a management session through a SIP message installed in the remote terminal 2000 and performs a management function of the remote terminal 2000. The remote management service agent 2100 performs a prescribed processing procedure through the SIP Subscribe, SIP info, and SIP notify messages in the remote terminal 2000, and the session-related message standard is linked with the remote management service controller 1200. Done.

In the present invention, SIP is used. Although there are many protocols for remote management (eg TR069, SNMP, etc.), SIP is a protocol that is basically supported by terminals with limited system environments such as VoIP phones. In other words, the SIP is lightweight so that it can be used in VoIP terminals with limited H / W preferences, thereby minimizing resource usage when mounted in other equipment. In addition, since it has a structure similar to the HTTP protocol, the usability (which can be easily interlocked by the developer of the product manufacturer) is high, and since the operation is based on UDP, there is an advantage of minimizing the load compared to HTTP based on TCP.

SIP is a protocol for VoIP, not a protocol for remote management. Therefore, conventional remote management methods do not use SIP, and remote management has a problem in that compatibility between other devices is difficult because it uses a manufacturer's individual protocol. In addition, a general management protocol such as SNMP and a method using WEB do not support a private IP environment.

Preferably, the SIP notify message and the SIP info message further include a Branch ID value used for identifying a work execution result for the work command.

Branch ID is a value used in the message header according to the NOTIFY message specification of SIP and serves as a unique identifier for transmission of the message.

When the SIP notify message header information Sample is as follows, z9hG4bK-d37-1163009863-19998-33 is the Branch ID.

NOTIFY sip: sipp@10.129.55.74: 5060 SIP / 2.0

The Notify message is a message used to instruct a remote terminal 2000 to maintain a SIP session. The job indicated by the Notify message takes the required file through HTTP or transmits the result file to the remote management service server 1100 using the SIP INFO message. At this time, the remote management service server 1100 should be able to identify which work instruction is the result file. For this purpose, a uniquely generated and maintained Branch ID value is used for each notify message. That is, the remote terminal 2000, which is a management target, maintains the branch ID value used for a specific work order and transmits the result of the work in an attribute value called branch ID when the remote management service server 1100 transmits the result. . The remote management service server 1100 records the operation log by matching the branch ID while storing the corresponding result value.

6 is an exemplary diagram of a logical configuration of the remote management service controller 1200.

The SIP Core module 1210 is a main module for transmitting and receiving a packet according to the SIP protocol, the Subscriber module 1220 is a module for maintaining a management session of a managed terminal (CPE) using a SIP SUBSCRIBE message, and a Notifier module 1230. ) Is a module that transmits a work instruction message (using a NOTIFY method) to the remote terminal 2000 to be managed according to a manager's work instruction, and the InfoWorker module 1240 is a remote terminal 2000 that has received a work instruction. It is a module that receives and processes the work result message when transmitting to the remote management service server 1100 (using the INFO method), and the RMS Controller Engine 1250 is a module that performs a service process and management function for performing a controller function.

Next, the information processing method of the remote session management control system will be described in more detail with reference to FIGS. 2 and 3.

2 is an exemplary diagram of an information processing method of a remote session management control system according to the present invention. The remote management session control system 1000 receives a SIP subscribe message from the remote terminal 2000 based on a preset time (S11), and manages the remote terminal 2000 with the received SIP subscription message. Check the session information (S12), and transmits a management command to the remote terminal 2000 using the management session information (S13), and receives the execution result of the management command from the remote terminal (2000) (S14). .

The session management module 1110 of the remote management service server 1100 processes a procedure of establishing a management session. The remote terminal 2000 accesses the remote session management control system for processing of a management session registration procedure using a SIP Subscribe message in a predetermined time unit (for example, every 60 seconds) or in a specific situation. The session management module 1110 of the remote session management control system checks any one or more of a phone number and MAC address information transmitted from the remote terminal 2000 so that the remote terminal 2000 controls the remote session management control system. After identifying whether the terminal is a management target terminal to be managed, if the management target terminal, the management session for managing the remote terminal 2000 is registered. If the remote terminal 2000 is not a phone, it can be identified by a MAC address. At this time, since it may be disguised as a registered terminal through the modulation of the phone number or MAC address of the remote terminal 2000, an additional authentication procedure may be performed in an area requiring security. In the case of the remote terminal 2000 registered in the management session, when the remote session management control system transmits a management command to the remote terminal 2000, IP and Port information that can be received by the corresponding remote terminal 2000 are included. In addition, the IP and Port information includes valid expired time information. After the end time has elapsed, the remote terminal 2000 transmits a SIP Subscribe message to the session management module 1110 of the remote session management control system to maintain the session. Registered remote terminal 2000 of the data unit 1170 of the remote management service server 1100 DB unit 1171 stores the IP, Port, Phone number, MAC address information, end time, etc. of the remote terminal 2000 do.

The preset time unit is about 60 seconds. In general, the IP of a terminal transmitted to the Internet in a private IP environment is changed to a public IP through a NAT / PAT device, and when a response packet arrives, the NAT / PAT device changes its IP to the original private IP and transmits it. Done. In a general environment, a NAT / PAT device does not have a fixed IP conversion policy, but dynamically uses available IP / PORT information each time. The IP / Port information used for serving other terminals is recovered as soon as possible, and the time from the allocation to the recovery is appropriate for about 60 seconds. If it recovers faster than this, the response to the requested terminal may be blocked if the result of the packet transmitted to the Internet is delayed, and if it is later, the multiple terminals may be inefficient in sharing a small number of IP / Port resources. In the present invention, since the session must be maintained, the subscribe message is repeatedly sent at an interval of 60 seconds in order to be able to immediately reassign the IP / Port information used when subscribing from NAT / PAT. That is, if the subscribe period is longer than 60 seconds, the delay of sending a notify message may occur as much as the interval. If the terminal to be managed is in an environment using public IP or private IP, and the environment operates with 1: 1 NAT as public IP, the subscriber only needs to perform it once when the device is rebooted or the IP of the device is changed. do.

After the session for remote management is established, the remote terminal 2000 transmits Inventory information including its configuration information and status information to the remote management service server 1100 using a SIP info message. The manager of the manager terminal 3000 can accurately check the situation of the management target terminal with inventory information.

Subsequently, when the manager of the manager terminal 3000 performs a management task on a specific remote terminal 2000 in which a management session is maintained, the corresponding work is registered with the remote terminal 2000 in the management session. Is sent using a SIP notify message. The remote management service agent 2100 of the remote terminal 2000 performs a work corresponding to each work command. When the remote management service agent 2100 needs to transmit a corresponding work result to the remote management service server 1100 according to a work, the remote management service agent 2100 transmits the work result using a SIP info message.

If the session is no longer maintained, the remote terminal 2000 transmits the SIP Subscribe message by setting the expired time value to "o". Upon receiving the message, the remote management service controller 1200 deletes the registration session for the remote terminal 2000. On the other hand, according to the same principle, the remote terminal 2000 which does not transmit the SIP Subscribe message again after the end time expires is naturally terminated.

The management function managed by the remote management service server 1100 may include the following.

The remote management service server 1100 performs an inventory management function, which is performed by the inventory management module 1120 of the present invention. The Inventory management module 1120 manages generation, modification, deletion, change history tracking, etc. of subscriber information, terminal information, and terminal setting information of the managed remote terminal 2000. When the remote terminal 2000 is a VoIP terminal, the terminal includes subscriber information such as a subscription ID, a PW, and a phone number because the terminal needs to access a service provider's network to receive a telephone service. Therefore, the inventory management module 1120 stores and manages the inventory information of each remote terminal 2000 in the form of subscriber information in consideration of the characteristics of the terminal information. When the subscriber remote terminal 2000 registered in the remote management service server 1100 accesses the remote session management control system through the wired / wireless network 4000, the subscriber remote terminal 2000 connects a management session to the remote management service controller 1200 and automatically establishes itself. Sends the terminal information to the remote management service controller 1200. The remote management service controller 1200 transmits the corresponding information to the management server and stores the information. The manager of the manager terminal 3000 may check the corresponding information through the manager WEB UI. The inventory DB unit 1172 of the data unit 1170 of the remote management service server 1100 generates, modifies, deletes, and changes history tracking information about subscriber information, terminal information, and terminal setting information of the remote terminal 2000. Etc. are stored.

 The remote management service server 1100 performs a configuration management function, which is performed by the configuration management module 1130 of the present invention. The configuration management includes various functions of generating a configuration file required for the remote terminal 2000 to be remotely managed and distributing the configuration file to the corresponding terminal. A value of a configuration parameter of a specific terminal can be changed, a simultaneous change operation of configuration parameters of a plurality of terminals (groups, models, etc.) can be performed, and periodic automatic distribution of configuration files can be performed. Through this, the administrator can not only change the desired setting of the terminal without direct visit processing when the operation environment changes for a large number of terminals, but also can check the current subscriber terminal setting information and diagnose the problem. Configuration files of the remote terminals 2000 are stored in the configuration file data unit 1173 of the data unit 1170 of the remote management service server 1100. The firmware files of the remote terminals 2000 are stored in the firmware data unit 1174 of the data unit 1170 of the remote management service server 1100, and the data unit 1170 of the remote management service server 1100. Job data of the remote terminals 2000 are stored in the job data unit 1175.

In FIG. 4, an example of an information processing method of the configuration management module 1130 is shown. The configuration management module 1130 generates a configuration management file for each type of the remote terminal 2000 (S21) and checks a condition for transmitting the configuration management file to be transmitted based on a specific time point with respect to the specific remote terminal 2000. After the transfer condition is satisfied (S22), the configuration management file is transferred (S23).

The configuration file is made in the form of a data file that can be accommodated in each of the remote terminals 2000 to be managed, and the download path information of the corresponding file is transmitted together with the work order. The transmission method may be a method of attaching a Bbranch Id as a tag when calling a download URL and requesting a configuration information file corresponding to the branch Id from the remote management service server 1100 in response.

The following example is an example of a configuration file for a VoIP phone, and may include any value required for setting the remote terminal 2000.

The remote management service server 1100 performs a firmware management function, which is performed by the firmware management module 1140 of the present invention. The firmware management module 1140 is a firmware image management (firmware registration, deletion, management information modification) for each terminal model for the remote terminal 2000 connected through the remote management service controller 1200, remote terminal 2000 ( It performs management tasks such as firmware upgrade of terminal) and tracking application status by firmware version (Inventory management association). The firmware management is an area that is the most difficult and expensive management costs for the administrator. The remote terminal 2000 must continue to be upgraded with new functionality along with implementing new service requirements. The administrator must upgrade the firmware of the terminal every time, or downgrade to the previous version if an unexpected error occurs after upgrading. Most managers will devote huge amounts of time and staff to the task. This management function helps to minimize this time and manpower input.

5 illustrates an example of an information processing method of the firmware management module 1140. The firmware management module 1140 registers firmware management information for each remote management terminal (S31), then checks the transmission condition of the firmware file (S32), and if the transmission condition is met, transmits the firmware file for each remote management terminal. (S33). The firmware installation information is received from the remote management service agent 2100 of the remote terminal 2000 (S34), and the firmware management information of the registered remote terminal 2000 is updated with the received installation information (S35).

Firmware of the remote terminal 2000 is generally provided by the manufacturer of the remote terminal 2000 in the form of a file. The manager may store the file in the remote management service server 1100 and manage the firmware name and version for each model of the remote terminal 2000. In order to apply the firmware that has been stably determined through the test to the remote terminal 2000 to be managed, a firmware download operation instruction is performed. The work instruction specifies the firmware name and version, and the remote terminal 2000 receiving the work instruction downloads and applies the firmware according to the contents of the work instruction message. When applying to multiple terminals at the same time, download is performed based on HTTP. Therefore, it is desirable to select the appropriate number of targets and to perform the work sequentially considering the processing capacity of the corresponding download server.

The remote management service server 1100 performs a state monitoring function of the remote terminal 2000, which is performed by the state monitoring module 1150 of the present invention. The remote terminal 2000 connected to the remote management service controller 1200 transmits a state value to the state monitoring module 1150 periodically or every time a state is changed from the time of the access, and the remote management service controller 1200 transmits the remote control. The state value data of the terminal 2000 is stored. The state monitoring module 1150 may provide a statistical report through the collected state value data, and the manager may support the corresponding terminal to check the service state of the corresponding remote terminal 2000 and to respond to the subscriber. do.

The remote management service server 1100 performs the thin line management function of the remote terminal 2000, which is performed by the session management module 1110 of the present invention. All remote terminals 2000 managed through the remote management service controller 1200 maintain a management session for the management. The list of remote terminals 2000 connected to and maintained in real time for the management can be checked in the remote management service server 1100. The session management module 1110 manages IP, port, phone number, MAC address information, end time, etc. of the remote terminal 2000.

The remote management service server 1100 performs a job management function of the remote terminal 2000, which is performed by the job management module 1160 of the present invention.

The task management module 1160 provides a function of instructing the remote terminal 2000 to perform a task of performing a specific management function to be performed when an administrator needs it. The remote management service controller 1200 transmits command information about performing the task of the task management module 1160 to the corresponding terminal through a connected session.
