Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining the configuration of an intelligent information providing system to help understanding of the present invention, it represents the hardware and software aspects at the same time.

Intelligent Peripheral (hereinafter referred to as IP) shown in FIG. 1 is a physical entity that provides a Specialized Resource Function (hereinafter referred to as SRF) in a distributed function plane defined in an intelligent network conceptual model. In order to provide an intelligent network service, one or more service switching points (hereinafter referred to as SSPs) (not shown), which are other network components, may be connected and service control points (hereinafter referred to as SCPs) of the service controller (not shown). On request, it connects SSP and voice channel and provides special resource through interaction with service user or collects information and delivers it to SCP.

In terms of hardware architecture, IP has a hierarchical structure of server-client type that stores and stores basic resources and special resources in different systems, and is referred to as a management and control unit (hereinafter referred to as MCU). 1), a resource switching unit (hereinafter referred to as RSU) 2, and a plurality of specialized resource units (hereinafter referred to as SRUs) 3. In this case, the RSU 2 provides basic resources such as fixed announcement, and the SRU 3 provides special resources such as voice recognition, speech synthesis, and fax, which are difficult to hold in the RSU 2. MCU (1), which acts as a server of IP, uses a workstation and controls the SRF service. By implementing the basic resource control service function in the RSU (2), SRF services requiring only basic resources can be independently provided by the RSU (2), thereby reducing unnecessary interfaces between the MCU (1) and the SRU (3). In addition, even if a failure occurs in the MCU 1 or the SRU (3) there is an advantage that can provide the basic resource services. The environment and interface of each system are as follows. Workstations using MCUs (1) and SRUs (3) use UNIX as their operating system and applications use the C language to implement their functions. RSU (2) uses CROS (Concurrent Real-time Operating System) and CHILL (CCITT High-Level Language) languages, and implemented using DREAM (Distributed Real Time Database Management) which is an exchange database. The communication between the MCU 1 and the SRU 3 uses a 100 Mbps LAN 6, and the communication between the MCU 1 and the RSU 2 uses a 10 Mbps LAN 7. At this time, the MCU 1 manages and maintains an internal database (DB) 12 and an external disk (DISK) 5. One or more operator terminals 4 are connected via a 10 Mbps LAN 7 for operation management and maintenance of IP.

On the other hand, in terms of software, IP is composed of four subsystems such as network matching unit 22, service control unit 23 and 32, resource control unit 24 and 33, and service operation management unit 11, 21 and 31. Each subsystem is distributed and implemented in each device depending on the function. The network matching unit 22 operates in the RSU 2 and is responsible for communicating with SCP, SSP, and other network elements in the intelligent network through the SS No. 7 link, and for exchanging information with a service user through a voice channel. It has a number of integrated telecommunication network / public switched telephone network (hereinafter referred to as ISDN / PSTN) interface. When the service control unit 23, 32 receives a request for resource usage from the service logic program of SCP through the network matching unit 22, the service control unit 23, 32 allocates the resource held by the IP system to the service user and collects additional information necessary for performing the intelligent network service. It also performs operator interaction to provide information to service consumers. At this time, the database is searched according to the logic program of the IP, and the service of the resource controller 24 and 33 is analyzed and allocated, initialized, occupied, restored, and rejected. The resource controllers 24 and 33 may transmit announcements, dual tone multifreguency (DTMF) digit collection, voice recognition, speech synthesis, voice recording, and fax, which are basic units of service for users to actually access IP. The resource function of the service is provided to the service user at the request of the service controller. In addition, it stores various types of information (audio, data, video) in the disk 5 and provides information input / output and editing functions therefor. System operation management unit (11, 21, 31) is largely implemented in the operation management, maintenance and operator matching functions of the system. It manages the status of hardware, software configuration data and various resources of the IP system, and collects various event and traffic data generated during system operation to calculate measurement and statistical data. In addition, it diagnoses the failure of the system and provides appropriate measures according to the level of failure, and performs call tracking function of test and resource provision service to easily handle the problem recovery with immediate report to the operator when a problem occurs in the system. It also provides various Graphic User Interface (GUI) functions between the system and the operator.

In FIG. 2, the disk file management apparatus includes a disk file management unit 202, 203, 204 distributed in each device, a plurality of operator terminals 205, and a local area network (LAN) of 10 Mbps / s in the MCU (1). ) Is connected to receive an instruction for file management, and the operator matching unit 201 for transmitting the processing result back to the operator terminal (205). At this time, the disk file managers 202, 203, and 204 perform file management functions such as file listing, information changing, copying, deleting, moving, editing, comparing, and contents output.

If the operator matching unit 201 sees a graphical user interface-based disk management window screen displayed on the plurality of operator terminals 205 and the operator selects a file management function using a mouse or a keyboard, at least a system identifier corresponding to the selected function is provided. Receives the disk management packet data including a, and notifies the operator terminal 205 of the processing result of the command again.

The disk file management unit 202 in the MCU 1 receives the disk management packet data from the operator matching unit 201, and the disk file management unit of the RSU 2 or the SRU 3 corresponding to the system identifier in the packet data ( 203 and 204, the result of the processing is notified again, and transmitted to the operator matching unit 201. In addition, when the system identifier corresponds to the device identifier, the corresponding disk management function is performed, and the result is notified to the operator matching unit 201.

The disk file management unit 203 in the RSU 2 receives the disk management packet data from the disk file management unit 202, and performs a corresponding disk management function when the system identifier corresponds to the disk management unit. 202).

The disk file management unit 204 in the SRU 3 receives the disk management packet data from the disk file management unit 202, performs a corresponding disk management function when the system identifier corresponds to the disk management unit, and returns the result to the disk file management unit ( Notify 2020.

The disk management table for performing the disk management function according to the present invention shown in FIG. 3 is maintained for each logged in operator in the MCU 1 and the SRU 3, and the RSU 2 has a single directory structure. Do not keep these tables as they are unnecessary. The disk management table includes a left window system identifier (LSID) of 4 bytes (301), a left window directory name length (302) of 4 bytes, a left window current of up to 256 bytes. Left Window Current Working Directory (303), 4-byte Right Window System IDentifier (RSID) 304, 4-byte Left Window Directory Name Length (305) , And Right Window Current Working Directory (RCWN) 306.

FIG. 6 is a flowchart illustrating an initialization process of a disk management function performed by the disk file managers 202, 203, and 204 of each device shown in FIG. 2.

In FIG. 6, the disk file management unit 202 in the MCU 1 initializes its own disk management table (601), and initializes a child process management table for managing child processes generated to execute a received command. (602). Subsequently, a communication socket (UDP / IP) for communicating with the operator matching unit 201 is allocated, and a communication socket (TCP / IP) to be used for communicating with the disk file management unit 203 in the RSU 2 is allocated. In operation 603, the processor 203 waits for a command received from the operator matching unit 201.

In FIG. 6, the disk file management unit 203 in the RSU 2 is allocated a communication socket (TCP / IP) for communicating with the disk file management unit 202 in the MCU 1, and from the disk file management unit 202. Wait for reception of an instruction of 606.

In FIG. 6, the disk file management unit 204 in the SRU 3 initializes its own disk management table (607), initializes the child process management table to manage the child processes created to execute the receive command, and 608, after receiving a communication socket (TCP / IP) for communicating with the disk file management unit 202 in the MCU 1 (609), and waits for receiving a command from the disk file management unit 202 (610). .

7A and 7B are flowcharts illustrating a disk file management method according to the present invention.

First, when an operator selects a disk file management function through a GUI-based disk management window as shown in FIG. 4 and a corresponding command is input (701), the operator terminal uses the disk management packet data shown in FIG. After transmitting to the matching unit (702), it waits for a response to the processing result (703). Meanwhile, the disk file management unit in the MCU receives the disk management packet data through the operator matching unit (706), retrieves the corresponding disk management table using the operator identifier (UIN) (707), and uses the system identifier (SID) command. Determine a system to process (707). If the SID is the MCU itself, it attempts to move to the operator's current working directory (CWD) (709). If the movement is successful (710), the reception command is performed (711), and the execution result is transmitted to the disk management window (712), and then waits for input of another command. If the move fails, an error message is generated (716), an error message is transmitted to the disk management window (717), and the input of another command is waited for. If the SID is not the MCU, the disk file management unit in the MCU transmits a command to a device corresponding to the SID (713) and waits for a command execution response (714). When the SRU and the RSU receive the command (718), the SRU searches the disk management table and attempts to move to the CWD of the corresponding operator (719), and if it succeeds (720) performs the receive command (721) and responds to the MCU. After transmitting to the disk file management unit (722), it waits for input of another command. If the move fails, an error message is generated (723), the error message is transmitted to the MCU disk file management unit (724), and waits for input of another command. Since the RSU disk file management unit does not manage a separate disk management table, after searching for a target file for performing the disk management function command (725), if the search is successful (726), the receive command (721 ') is performed. After sending the response to the MCU disk file management unit (722 '), it waits for input of another command. If the search fails, an error message is generated (723), the error message is transmitted to the MCU disk file management unit (724), and the input of another command is waited for. The disk management window receives the result response (704), updates the content of the disk management window according to the result response (705), and then waits for the operator's command input again.

8A to 8C are flowcharts for describing a working directory moving process in each device of the intelligent information providing system according to the present invention.

In FIG. 8A, the MCU disk file management unit receives an instruction requesting a directory movement or a system movement (in this case, a directory name requesting the movement becomes “ROOT”) through the operator matching unit, and the SID requested first is displayed. Check whether the MCU (801). If the SID is an MCU, the MCU disk file management unit checks the requested directory name and if the directory name is ROOT (802), attempts to move to the default directory (803) otherwise, first moves to the CWD of the operator (808). Attempt to move to the requested directory (809). If the move is successful (804) and attempts to generate the information of the directory (805), if successful (806), the directory information is transmitted to the operator terminal to update the disk management window (807). If the movement to the base directory fails or the information generation of the directory fails, an error message is generated (810) and an error message is transmitted to the corresponding operator terminal and notified to the operator through the disk management window (811). If the SID is not the MCU, the MCU disk file management unit transmits a command to the corresponding SID (812) and waits for a response (813). If the received response 814 is normal (815), the received directory information is transmitted to the corresponding operator terminal to update the disk management window (816). Otherwise, an error message is generated (810) to generate an error message to the disk management window. The operator is notified of this through 811.

8B, when the disk file manager in the RSU receives the directory move command, attempts to generate the directory information (817), and succeeds (818). The directory information is transferred (819) to the disk file manager in the MCU. If not, generates an error message (820) and transmits the error message to the disk file management unit in the MCU (821).

In FIG. 8C, when the disk file manager within the SRU receives a directory move command, first, if the requested directory is named ROOT (823), it attempts to move to the default directory of the SRU (824). After moving to CWD (829), it attempts to move to the requested directory (830). If the move is successful (825) and attempts to generate the directory information (826) and if the creation is successful (827), the directory information is transmitted to the disk file management unit in the MCU (828). If the move to the directory fails or the generation of information fails, an error message is generated (831) and an error message is transmitted to the disk file management unit of the MCU (832).

9A to 9D are flowcharts illustrating a file transmission / reception process in each device of the intelligent information providing system according to the present invention.

As shown in the figure, when the MCU disk file manager receives a file copy / move command through the operator matching unit (901), the MCU disk file manager first searches for the SID in which the original file is located (902). If the source SID is an MCU, the target SID is searched. (903) If the destination SID is an MCU, the MCU disk management unit executes a file move / copy command (904). The information is generated (906) and sent to the disk management window (907). If the command execution result is not normal, error information is generated (917) and error information is transmitted (918). In step 903, if the target SID is not the MCU, a file reception request is transmitted to the target SID (908). When the reception wait signal is received from the target SID (909), the file is transmitted to the corresponding SID (910), and when the file information is received (911), the file information is generated (908) and the file information is transmitted to the disk management window. (907). After receiving the error information in the above step 909 or the error information in the above step 911, after generating error information to be transmitted to the disc management window using the received error information (917), the disc management window The error information is transmitted (918). In step 902, if the original SID is not the MCU, the target SID is checked (912). If the target SID is the MCU, the file transmission request is transmitted to the original SID (913). When the file information is received (914), the reception wait signal is transmitted to the corresponding original SID (915), after receiving the file (916), the file information is generated (908), and the file information is transmitted to the file manager GUI window (907). ). When the target SID is not the MCU in step 912, the source SID is compared with the target SID (919). If the same, if the file information is received after transmitting a local file move / copy command to the corresponding source SID (920). (911) File information is generated (906) and file information is transmitted to the disk management window (907). When the error information is received in step 911, error information to be transmitted to the disk management window is generated using the received error information (917), and the error information is transmitted to the disk management window (918). If the two SIDs are incorrect in step 919, after transmitting the file transmission request to the original SID (921) and receiving the file information (922), the MCU disk file management unit transmits the reception wait signal to the original SID (923). ). After receiving the file from the original SID (924) and sends the file receiving request to the target SID (925). When the reception wait signal is received from the target SID (928), the file is transmitted (927). When file information is received from the target SID (928), the file information is generated (906) and the file information is transmitted to the file manager window (907). . When the error information is received in the above-described steps 922, 926, and 928, error information to be transmitted to the disk management window is generated using the received error information (917), and the error information is transmitted to the file manager window (918). ).

When the SRU / RSU's disk file management unit receives a local file move / copy command (929) When the SID corresponds to the SRU (930) After moving to the CWD of the operator (931) When the original file search is successful (932) The existence of the target file is checked (933). In this case, if the target file does not exist, the local file move / copy command is executed (934). If the execution is successful (935), file information is generated (936), and the file information is transmitted to the MCU disk file management unit (937). ) Wait for command input. If the original file search fails in the above-described step 932, or if the target file exists in the above-described step 933, error information is generated (938), and the error information is transmitted to the MCU disk file management unit (939). ) Wait for command input. In this case, when the SRU / RSU disk file management unit receives a file transmission request (940), when the SID corresponds to the SRU (930 '), the user moves to the CWD of the corresponding operator (931') and the file search is successful (941). The information is generated (942) and the file information is transmitted to the MCU disk file management unit. When the reception wait signal is received from the MCU disk file management unit (944), after the file is transmitted (945), a command input is waited. If the file retrieval fails in the above-described step 941 or the file information generation fails in the above-mentioned step 942 and the reception wait signal is not received in the above-mentioned step 944, error information is generated ( 933 ') After transmitting error information to the MCU disk file management unit (939'), it waits for a command input. When the disk file manager of the SRU / RSU receives a file reception request (946), when the SID corresponds to the SRU (930 '), the SRU / RSU moves to the CWD of the corresponding operator (931') and searches for the existence of the target file (947). . If the target file does not exist, the file is generated (948) and the reception wait signal is transmitted to the MCU disk file management unit (949). After receiving a file from the MCU disk file management unit (950) and generating file information (951), the file information is transmitted to the MCU disk file management unit (952), and then waits for a command input. If the target file exists in step 947 above, or the file generation fails in step 948 described above, and fails to generate the file information in step 951 described above, error information is generated (938 '). After the error information is sent to the disk file management unit (939 '), the command input is waited.
