The present invention relates to a mobile exchange, and more particularly, to a statistical data storage and transmission system and method for storing and transmitting statistical data on the operational status of each device in the mobile exchange to the network operations center.

In general, as shown in Fig. 1, a mobile exchange realizes the overall function of an Access Switching Subsystem (ASS) that performs the overall function of localized call processing, centralized call processing. Three subsystems, the Interconnection Network Subsystem (INS) 160 and the Central Control Subsystem (CCS) 110, which are responsible for centralized operation and maintenance functions. Storage device 170.

The ASS includes a wired subscriber call control unit (ASS-S) 120, a wireless subscriber call control unit (ASS-M) 130, and a relay line call control unit (ASS-T) 140.

The INS 160 includes a space switch 163 for connecting each call controller 120-140, and a switching network controller 161. The INS 160 connects the CCS 110 and the control unit 120-140 of the ASS or ASS, performs number translation, route control, centralized call processing, and performs network synchronization.

The CCS 110 provides a communication window and means between the MSC 100 and the operator. The CCS 110 defines the interaction between the mobile exchange and the operator to provide functions such as operator matching, charging, traffic measurement, and network management data management. It performs the operation maintenance and various statistical functions of the system and controls various inputs and outputs from the control and management of the storage device 170 and the operator. The CCS 110 is provided with an Operation Maintenance Processor (OMP) 111 that is a processor that controls input / output operations with an operator for operation and maintenance. The OMP 111 is connected to a network with an NMS (Network Management System) 105 which is an operator computer.

The NMS 105 is provided with a man machine interface (MMI), which is an operator interface program, to receive a command from an operator. The OMP 111 also collects and accumulates network status, alerts, traffic data, and the like, and calculates network management parameters and statistical data.

The mobile switch 100 is provided with a system for storing and transmitting statistical data. Specifically, as shown in FIG. 2, the statistical data storage and transmission system includes a statistics collector 101 for storing the statistical data in the storage device 170 of the mobile exchanger 100, and the periodic statistical data in the mobile exchanger ( Statistical processing unit 103 for reading and outputting from storage device 170 of 100, and NMS 105 for transmitting the output periodic statistical data to network operation center 107.

The statistics collecting unit 101 collects the statistical data at a predetermined period (for example, about 5 minutes) from the access switching subsystem (ASS) or the interconnection network subsystem (INS) 160, and stores the statistical data in a memory. To store in the storage device 170. The statistics collecting unit 101 is a software block implemented in the OMP 111 of the MSC 100.

The statistical processing unit 103 is configured to read periodic statistical data from the storage device 170 and output the statistical data stored in the storage device 170 through the MMI periodically according to the output time and output items preset by the operator. Output the data. The operator can divide the periodic statistics output time into appropriate time units (e.g. every 5 minutes / hourly / daily / monthly) and set the statistical items to be output for each output time. The statistical processing unit 103 is a software block implemented in the OMP 111 of the MSC 100.

In general, the functions of the statistics collector 101 and the statistics processor 103 are performed by a measurement and statistics data processor (MSDP) provided in the OMP 111. The MSDP receives the operator's request measurement command from the MMI of the NMS 105, analyzes it, drives the measurement unit (for example, ASS or INS, etc.) to start the measurement, and collects and outputs the measurement result. Alternatively, the MDSP makes regular measurements according to the plan and outputs the measurement data at the output point specified by the operator.

The NMS 105 is connected to the network of the OMP 111 of the MSC 100, receives statistical data from the OMP 111, and outputs the statistical data through the MMI, thereby allowing the operator to retrieve the statistical data. In addition, the NMS 105 periodically converts the statistical data into a specific format (for example, XML (eXtensible Markup Language) format), stores the data, and transmits the statistical data to the network operation center 107. When the NMS 105 receives a request for retransmission of the statistical data from the network operation center 107, the NMS 105 receives a command to read the statistical data in the storage device 170 of the mobile switching center 100 through the MMI 70 and transmits the same. do.

On the other hand, the conventional method of transmitting statistical data, as shown in FIG. The statistical data is transmitted from the statistics collecting unit 101 to the statistical processing unit 103 at a predetermined period (for example, 5 minutes) (S101). After receiving all the statistical data from the statistical processing unit 103, the statistical data is stored in the storage device 170 (S102). The MMI determines whether to output periodic statistical data for each statistical item according to an operator command (S103). The NMS 105 receives the statistical data and outputs it through the MMI (S104), and stores the statistical data output to the MMI in a specific data format (for example, an XML file) (S105). The NMS 105 transmits statistical data to the network operation center 107 by FTP (S106). Here, the network operation center 207 receives the statistical data and uses the traffic congestion control, network configuration optimization, etc., and requests the NMS 105 to retransmit the statistical data if necessary.

On the other hand, the conventional statistical data retransmission method, as shown in FIG. The network operation center 107 requests the statistical data retransmission to the NMS 105 (S111). The operator inputs a command to read statistical data stored in the storage device 170 through the MMI of the NMS 105 (S112). The OMP 111 determines whether statistical data is stored in the storage device 170 (S115). The NMS 105 receives the statistical data from the OMP 111 and transmits the statistical data to the network operation center 107 using FTP again (S116).

However, in the conventional method of processing periodic statistics, since the statistical data stored in a certain period (for example, five-minute cycle) is stored in a specific data format such as ASCII format, the storage time and items of the statistical data increase. As a result, the file size storing the statistical data is also rapidly increased, and the load is increased when the storage device 170 is read. Therefore, the storage device 170 stores only statistical data for a predetermined time (for example, 24 hours).

Since the NMS 05 transmits only the periodic statistical data output through the MMI to the network management center 207, when the operator does not set the statistical data to be transmitted, the network management center 107 transmits the statistical data in real time. I can't accept it. In addition, setting up operators to send dozens of statistical items via MMI is very cumbersome and time consuming. Hundreds of statistical data set up for a specific statistical item can be converted into a specific data format such as an XML file at once. Not only can it not be sent at once, but also takes a lot of load even if it is divided.

When the statistical data retransmission request is requested from the network management center 107, the operator may input the command to read the statistical data transmitted to the exchange to retransmit the statistical data to the network management center 107.

An object of the present invention is to store the statistical data in the mobile switching center and transmit it to the network management center in real time, and to reduce the file size by storing the statistical data in the form of RRI (Real Source Interface) packet load during data transmission It is to provide a system and method for storing and transmitting statistical data of a mobile exchange that can reduce the number of mobile communication.

According to an embodiment, the MSDP collects statistical data from the ASS or INS, converts the collected statistical data into RRI packets in a Telecommunication Management Network (TMN), and transmits them to an RRI agent, and the RRI agent provides statistical data in an RRI packet format. Is stored in the storage in the mobile exchange and then sent to the network operation center. Here, MSDP and TMN and RRI agents are implemented in OMP at the mobile exchange.

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

5 is a block diagram of a statistical data storage and transmission system according to an embodiment. The statistical data storage and transmission system shown in FIG. 5 may be installed and used in the exchange 100 as shown in FIG. 1, for example. Therefore, hereinafter, a detailed description of the components having the same functions as those shown in FIG. 1 will be omitted.

As shown in FIG. 5, the statistical data storage and transmission system includes a statistics collector 510, a statistics processor 530, and an RRI agent 550. When the statistical collecting unit 510 transmits the statistical data signal to the statistical processing unit 530 every 5 minutes, the statistical processing unit 530 converts the statistical data into an RRI packet form and transmits the statistical data to the RRI agent 550. . The RRI agent 550 generates a statistics file, stores the statistics file in a storage device 170 such as a hard disk, and transmits the statistics file to the network operation center 570. For example, the transfer of the statistics file may be in accordance with a file transfer protocol such as FTP (File Transfer Protocol). When the network management center 570 requests the statistical data retransmission, the RRI agent 550 reads the statistical file from the storage device and transmits the statistical file to the network management center 570 via FTP. RRI packet data has simpler data handling and easier processing of graphics and accelerators than XML data.

6 is a block diagram illustrating a detailed configuration of the statistical data storage and transmission system of FIG. 5. Statistical data storage and transmission system, as shown in Figure 6, MSDP (510 ') functioning as a statistical collector 510 for collecting statistical data, converts the statistical data into a Real Source Interface (RRI) packet form RRI for receiving statistical data from Telecommunication Management Network (TMN) 530 ', TMN 530' which functions as a statistical processor 530, and storing the data in a storage device and transmitting it to the network operation center 570. The agent 550, the network management center 570 receives the stored statistics file from the RRI agent 550.

In general, the OMP 111 oversees a series of operations and maintenance related functions within the mobile exchange, and controls the auxiliary storage required for this. The auxiliary storage device stores charge records, statistics, maintenance and operation management information. According to one embodiment, both MSDP 510 ', TMN 530', and RRI agent 550 may be implemented in software or hardware in Operation and Maintenance Processor (OMP) 111 of MSC 100. .

MSDP 510 ′ collects statistical data from ASS and INS 160. The TMN 530 ′ is a statistical processor that converts the statistical data into an RRI packet and then transmits the statistical data to the RRI agent 550.

The RRI agent 550 receives an RRI packet, which is an interface for real-time data transmission, stores the RRI packet in an exchange storage device and transmits the data to the network operation center 570. According to an embodiment of the present disclosure, the RRI agent 550 may transmit data in an RRI packet format to the NMS 105 of FIG. 1 and display the data on the operator screen of the MMI.

In one embodiment, TMN 530 ′ interfaces with RRI agent 550 using a communication protocol such as Inter Processor Communication (IPC).

The network operation center 570 monitors network functions by receiving statistical data from the RRI agent 550 in a real time unit of a predetermined time unit (for example, 5 minutes), and when retransmission of the statistical data is required, the RRI agent 550 Retransmit request to receive statistical data.

The operation of the system according to the embodiment having the above configuration is as follows. At certain intervals (eg, every 5 minutes), the MSDP 510 'collects statistical data from the ASS or INS 160, another main processor of the exchange. The TMN 530 ′ converts the statistical data collected from the ASS or INS 160 into RRI packets, and then transmits the statistical data to the RRI agent 550. The RRI agent 550 stores the transmitted RRI packet in a storage device as a statistical file in a predetermined period (for example, 5 minutes RRI format). The RRI agent 550 stores the stored statistical data in the network operation center 570. When the statistical data retransmission request is requested from the network operation center 570, the RRI agent 550 may read the statistical data from the storage device and transmit the statistical data to the network operation center 570.

7 is a flowchart illustrating a method of storing and transmitting statistical data, according to an exemplary embodiment. As illustrated in FIG. 7, the statistical collector 510 collects statistical data and transmits the statistical data to the statistical processor 530 every predetermined period (for example, about 5 minutes) (710). For example, the MSDP 510 ′ implemented in the OMP 111 of the MSC 100 may operate as the statistics collector 510 to transmit statistical data to the statistics processor 530. After receiving all the statistical data from the statistical processing unit 530 converts to RRI packet form and transmits to the RRI agent 550 (720). For example, the TMN 530 ′ implemented in the OMP 111 of the MSC 100 may operate as the statistical processor 530 to convert statistical data into an RRI packet. The RRI agent 550 receives and stores statistical data (730). For example, the RRI agent 550 may store statistical data in the storage device. The RRI agent 550 transmits statistical data to the network operation center 570 (740).

8 is a flowchart illustrating a statistical data retransmission method according to an embodiment. As shown in FIG. 8, when the network operation center 570 requests the statistical data retransmission (810), the RRI agent 550 checks whether the statistical data is stored in the storage device (820). If the statistical data is stored as a result of the check, the RRI agent 550 transmits the retransmission requested statistical data to the network operation center 570 using FTP (830).

Accordingly, since the mobile exchange transmits the statistical data in the RRI format directly to the network operation center 570 without passing through the NMS (Network Management System) 160, the statistical data can be transmitted in real time, and the statistical data in the form of an RRI packet. By storing and transferring, the file size can be reduced, thereby reducing the load during data transfer.
