Description

An apparatus for unitedly managing system of multi-vendor}

The present invention relates to an apparatus for integrated management of a system of a multi-vendor. More particularly, the present invention relates to a multi-vendor base station (Node B) or a control station (RNC) of an interoperability in an IMT-2000 system. It's about a device that allows for integrated management.

The third generation mobile telecommunications service, called International Mobile Telecommunications (IMT-2000), is a mobile telecommunications system that makes recommendations in the TG / 1 of ITU-R aiming at the service in the early 2000s.

This third generation mobile communication system is a mobile communication system that uses a wireless link to connect various communication services supported by a fixed communication network such as PSTN / ISDN / B-ISDN according to a mobile user's request.

The frequency bands used are 1,885 MHz to 2,025 MHz and 2,110 MHz to 2,200 MHz, which are determined by WRC-92. In the next generation mobile communication system that can provide not only the existing communication service but also a higher level of service by improved technology. Various types of mobile terminals that can be connected to terrestrial or satellite networks are used for mobile or fixed communication.

IMT-2000 is able to interoperate with various systems, has high service compatibility by worldwide operation, and has the features of using small size and light weight terminal with high quality.

IMT-2000 is a mobile communication system that provides not only voice and data but also multimedia services such as high-speed data and video communication up to 2Mbps. It adopts the concept of layer cell (pico, micro, macro cell, etc.) I aim to roam.

In addition, IMT-2000 uses a total of 230 MHz in the common frequency band (1,885 MHz to 2,025 MHz, 2,110 MHz to 2,200 MHz) worldwide, and the satellite portion of the IMT-2000 is limited to the bands 1,980 to 2,010 MHz and 2,170 to 2,200 MHz. As a result, international roaming is possible because it uses a common wireless standard.

In this way, IMT-2000 integrates the existing terrestrial mobile communication and satellite mobile communication systems so that the mobility of the terminal can be freely moved, the personal mobility that the subscriber can receive from any terminal, and the voice on the go. It aims to satisfy the service mobility and the like that can be used.

In other words, IMT-2000 is a third generation mobile communication system that integrates existing mobile communication systems to provide international roaming services, multimedia services, and personalized communication services.

In particular, the IMT-2000 ensures an open interface so that even if multi-vendors each manufacture a base station Node B or a control station RNC, there is no problem in interworking. Standards are standardized by the 3GPP International Standardization Organization.

However, even if the system is implemented using a standardized protocol, each system implemented by each vendor has a different structure of hardware or operation management (OM) design structure set by each vendor. Integrated management in the Management System is not possible. In other words, even if communication between systems is possible, it is impossible to integrate and manage each system.

This is similar to the current 2G system, and each vendor's base station management unit (BSM) of each 2G system exists and cannot be integrated.

Consider some ways to solve this problem.

First, as shown in Figs. 1 and 2, each element management system 2, 4 for each system is implemented. For example, in Fig. 1 is implemented as a base station of Company A, a control station 1 of Company A, an element management system (2) of Company A, in Figure 2 is a base station of Company B, a control station 3 of Company B and Company B of It is implemented with the element management system 4. However, it is possible to separate and monitor the object to be integrated and managed by several element management systems. Also, since the user interface is different from system to system, it is difficult for the operator to monitor the system efficiently and must adapt to various user interfaces. Causes several negative consequences.

Second, it creates a standardized Management Information Base (MIB) and designs and implements a system based on it. In this case, as shown in FIG. 3, a single element management system 4 can consistently manage and integrate several systems. However, this may result in limiting the originality of the system design to be guaranteed by the vendor and limiting the characteristics of the system, and has the disadvantage that the integrated system cannot be managed. That is, in FIG. 3, the signaling path and the monitoring / control path between the BS B base station, the B company control station 3, and the B company element management system 4 will be described. Although both the monitoring and control through the company B element management system 4 are possible, the company A in the signaling path and the monitoring / control path between the company A base station and the company B control station 3 and the company B element management system 4 can be used. Even if signaling between the base station and the company B control station is possible, monitoring / control by the company B element management system 4 is not possible.

In conclusion, there is a need for a method that can provide the user with a consistent user interface through a single element management system while maintaining the characteristics of each system for multiple systems developed by multi-vendors and enabling interworking of already developed systems. It is true.

The present invention has been proposed in view of the above-described conventional situation, and provides an apparatus for integrating and managing a system of a multi-vendor system to ensure maximum independence of a management information base for each system to maximize the system characteristics that can be differentiated by vendor. The purpose is to provide.

Another object of the present invention is to provide an apparatus for integrating and managing a system of a multi-vendor to provide a consistent user interface and management scheme to an operator.

In order to achieve the above objects, an apparatus for integrating and managing a system of a multi-vendor according to a preferred embodiment of the present invention includes a user interface that is responsible for interfacing with a user, failure / failure and performance state and shape information of a network element. An application layer unit having a management unit for managing and informing the operator of the result through the user interface; Common means constituted by an abstraction layer unit provided between the systems of the plurality of vendors and the application layer unit so that the systems of the plurality of vendors share the application layer unit; And driver combining means which is provided for each vendor's system, manages the vendor's system, receives the status report from the vendor's system, and transmits the status report to the common means.

Hereinafter, an apparatus for integrated management of a system of a multi-vendor according to an embodiment of the present invention will be described with reference to the accompanying drawings.

4 is a configuration diagram of an apparatus for integrated management of a system of a multi-vendor according to an embodiment of the present invention, wherein the integrated element management system 6 is matched to the common unit 30 and the common unit 30, respectively. A plurality of driver coupling portions 40, 50 are provided to manage the respective vendor systems 60, 70 below.

The common unit 30 is an integrated graphical user interface 10 that provides an interface for transmitting a system operation status to an operator using a graphic for the operator's convenience of operation, and a user interface that interfaces with a user. (12), an error management unit 14 for managing a failure / failure of a network element, a performance management unit 16 for managing a performance state of the network element, and a shape management unit 18 for managing shape information of the network element. An application layer section with a; And an abstraction layer unit 20 installed between the application layer unit and the hardware of each vendor system so that the application layer unit can control and manage the hardware of each vendor system.

The error management unit 14 reports a failure / failure state of each network element and a network element sub unit, and informs the operator of the reported information through the user interface 12.

The performance management unit 16 reports the operating performance of each network element and the network element subunit, and informs the operator of the reported information through the user interface 12. In most cases, the results of the performance management unit 16 are reported in the form of statistical values.

The configuration manager 18 reports the shape information and the status of each network element and the network element subunit, and informs the operator of the reported information through the user interface 12.

The driver coupling unit 40 includes a driver 32 matching the abstraction layer unit 20; And a management unit 34 connected to the driver 32 and managing a sub-system (that is, the vendor system 60) to be managed. The driver coupling unit 50 also includes a driver 42 and a manager 44 that perform the same function. The management unit 44 manages the vendor system 70.

Each vendor develops and installs drivers 32 and 42 for interworking with the integrated element management system 6 (that is, interworking with the abstraction layer unit 20) and installs the integrated element management system 6. If (install), the common unit 30 can be shared and used.

In each of the vendor systems 60 and 70, a target to be managed for management of the system is determined in advance, and after the list is determined, the status of the target is reported to the corresponding management unit and operated according to the instructions from the management unit. Agents 52 and 62 are provided. The agent 52 transmits and receives signals and data to and from the manager 34, and the agent 62 transmits and receives signals and data to and from the manager 44. The agents 52 and 62 have their respective management information bases MIB.

The management units 34 and 44 predetermine targets to be managed for the management of the sub-system (vendor system), and after the list is determined, the statuses of the targets determined from each agent are reported, and a series of functions are performed according to the report results. Perform. The management units 34 and 44 incorporate respective management information bases MIB.

If the vendor making the system is different, such as A and B, the units or performance management parts inside the system to be monitored by A and B are different, and therefore the objects to be managed are also different. Accordingly, the management information base MIB varies from vendor to vendor. Therefore, the independence of the agents 52 and 62 and the management units 34 and 44 for each system made by each vendor must be ensured, and the matching with the abstraction layer unit 20 must be made. Therefore, the driver coupling units 40 and 50 have a form in which drivers 32 and 42 capable of matching with the abstraction layer unit 20 and management units 34 and 44 capable of managing a lower system are integrated. Achieve.

The abstraction layer unit 20 is interworked with the application layer unit in a predefined manner, and also with hardware of each vendor system through drivers 32 and 42. Accordingly, the application layer unit does not directly control and manage the hardware, but controls and manages the hardware through the drivers 32 and 42 by interworking with the abstraction layer unit 20.

This driver method is a method that allows the application layer unit to match with various hardware while minimizing the possibility of change for the hardware. Since the hardware manufacturer also needs to consider only the interworking with the abstraction layer unit 20, a separate application layer You do not have to worry about wealth.

FIG. 5 is a diagram for explaining a relationship between an integrated element management system and heterogeneous base stations in an embodiment of the present invention.

The system of company A (including base station) and the system of company B (including base station) not only have different hardware structures, but also management information bases (MIBs) for managing each other's operation management (OM). Thus, the integrated element management system 6 employs a driver scheme to manage them collectively.

In FIG. 5, when the control station 5 is a control station of Company B, a signaling path and a monitoring / control path between the Company B base station, the Company B control station 5 and the integrated element management system 6 will be described. Both signaling between the base station and the company B control station 3 and monitoring / control via the integrated element management system 6 are possible. In addition, the signaling path and the monitoring / control path between the A company base station, the B company control station 5 and the integrated element management system 6 will be described. Monitoring / control via (6) is also possible.

In other words, the integrated element management system 6 appears to the operator as an integrated element management system, but within the integrated element management system 6 there is a separate element management having a respective management information base (MIB) management unit. Same as the system exists. However, the commonly used tools are composed of separate modules and used by systems manufactured by each vendor.

In order to build an integrated element management system through the driver method as described above, it is necessary to prepare a standard draft for driver creation and an initial investment to build a common platform.However, once a standard draft and a common platform are established, any vendor The system may also be accommodated in its integrated element management system.

As described in detail above, according to the present invention, the management of a system of a multi-vendor can be integrated into a single integrated element management system employing a driver method, thereby maximizing system characteristics that can be differentiated from vendor to vendor. Instead, operators do not need to learn how to use multiple element management systems, thereby reducing the time and cost of training personnel to operate the system.

And, in the case of the service business, it is possible to accommodate any number of systems produced by various vendors, it is possible to select and use a variety of systems according to the necessary purpose.

In addition, the operator can operate the system of multiple vendors through a single user interface, which increases the convenience of operation, and the system developer does not need to develop a separate element management system, thereby reducing the production cost and the related labor cost. You get
