The present invention relates to a network management system. In particular, in the operation and management of network elements through an element management system (EMS), a user logs in to an element management system. By selecting the client-server environment or the stand-alone environment and operating the element management system, the system is managed through the server according to the user's convenience (for example, the size of the network configuration). It is possible to decide whether to run the system in a stand-alone state or directly in a stand-alone state, and even if a server problem occurs, stand-alone form directly from the client, independently of the server, The element management system supporting a plurality of operating environments and the control method thereof capable of operating the system. All.

In operating and managing a communication network, an element management system (EMS) provides management services in the form of a client-server environment or a stand-alone environment. The element management system selects and implements one of the above environments and executes the operation program according to the determined environment.

In other words, in a client-server environment, two separate processors, a client (PC) and a server (workstation, PC server, etc.) operate to manage each network element (NE), and the user If you want to set up, inquire, delete, and change the information, you must deliver the information through the server, and even if you receive the information from a specific network element, it is operated in the form of receiving the information through the server.

In a stand-alone environment, there is one client (PC) or server (usually a workstation) to manage each network element, and the user wants to set up, query, delete, and change the information of a specific network element. It operates in the form of directly transmitting and receiving information to the network element, and operates the database directly in one operating PC or workstation. Therefore, it is impossible for multiple users to add, delete, change, and query one database at the same time.

In a client-server environment, one server can have multiple clients, and multiple operators connect to one server to operate each network element, and each client adds or deletes information to the database of the same server. By changing and querying, multiple operators can manage network elements in the same environment at the same time, while in stand-alone environments, clients can be managed simultaneously on one element management system (ie, one PC or workstation). And it can proceed with the role of the server, each network element can be managed without a separate server, but multiple operators can not manage the network element in the same environment at the same time.

However, when the element management system is operated in a client-server environment, if a problem occurs in the server, the operation of each network element may occur until the problem of the server is resolved in the client, where the client-server By changing the environment into a stand-alone environment and executing the program, each network element can be operated without access from the client to the server. However, the conventional general element management system does not support both the client-server environment and the stand-alone environment. Not only that, there was also a problem that it is impossible to change the operating environment of the element management system from a client-server environment to a stand-alone environment according to the network operating state during operation.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems. In the operation and management of a network element through an element management system (EMS), a user logs in to the element management system. The object of the present invention is to provide a system and a control method for operating an element management system by selecting a client-server environment or a stand-alone environment in a log-in step.

In order to achieve the above object, the present invention provides an element management system (EMS), wherein the element management system includes a client program and a server program required for operation of a client-server environment. Equipped with a user interface that allows the user to select a management service, either client-server or stand-alone, when the user attempts to log in. Depending on the service, it is characterized in that it comprises one or more EMS clients running the client program to operate in a client-server environment, or running the server program in a stand-alone environment.

In addition, the present invention provides a system user log in an element management system (EMS) capable of supporting management services in a client-server environment and a stand-alone environment. in) attempting to activate a user interface for selecting a management service from an Element Management System (EMS) client; Selecting a management service through the activated user interface and executing a client program or a server program to operate as a client in a client-server environment or as a server in a stand-alone environment;

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

3 is a flowchart illustrating an operation process of a control method of an element management system supporting a plurality of operating environments of the present invention. As shown in FIG. 3, a client-server environment and a stand-alone environment are shown. -Alone) In an element management system (EMS) capable of supporting management services in an environment, when an attempt is made to log in from an element management system (EMS) client, a management service is provided to the EMS client. Receiving a selection of an execution environment by activating a user interface for selection (S30 and S31); If an error occurs in the EMS server during the operation of the system in the client-server environment by the selection, retrying login and selecting a stand-alone environment through a user interface for selecting a management service (S32 to S35). )Wow; According to the selected stand-alone environment, the server collects information about a network element (NE) connected to the element management system through the execution of a server program in the MS client, database, and operates the system (S36). Configure.

Through the above configuration, the present invention provides a client in the step of logging in to the element management system in the user operating and managing the network element (Network Element) through the Element Management System (EMS) By selecting element as a client-server environment or stand-alone environment, the element management system can be operated. It is possible to decide whether to operate the system, and even if a problem occurs in the server, the system is operated by itself in a stand-alone manner, without going through the server.

The present invention can be applied to an element management system (EMS) capable of supporting management services in a client-server environment and a stand-alone environment, and is illustrated in FIG. As described above, the network management system 30 is in charge of the operation and management of the overall communication network, and the element management systems 20 to 22 optimize network performance in terms of operation of various kinds of network elements 10 and 11. It performs real-time monitoring and control, collects a series of information related to the configuration and performance of equipment, information related to faults and alarms, etc., and performs network operation and maintenance. ) Refers to a device to be managed, such as a router, a switching hub, and an ATM switch.

And in more detail look at the configuration of one of the element management system (20 to 22), as shown in Figure 2, the plurality of device interlocking parts (220, 221) to collect the fault information transmitted from each of the network elements (210, 211) The server database 230 stores a series of information related to the configuration or performance of the network elements 210 and 211 and information related to a failure or alarm transmitted from the device interlocking units 220 and 221. In addition, the EMS server 240 plays a role of controlling and managing the network elements 210 and 211 under a management service of a client-server environment. Allow for quick and accurate fault handling

In addition, the plurality of EMS clients 250 and 251 are equipped with a client program and a server program required for the operation of the client-server environment management service, and the client-server when a user attempts to log in. It supports the user interface to select the management service of the environment or stand-alone environment, and depending on the management service selected by the user, run the client program to operate as a client-server environment or In addition, the server program executes the server program and operates as a stand-alone environment through a server thread. In addition, the MS client 205, 251 should play a role of a client or a server according to each management service, so that physical components such as a network module for implementing a server thread should be included.

The stand-over database 260 is operated when the EMS client 250 or 251 is operated in a management service of a stand-alone environment and the server program is executed, and the device is controlled according to the control of the MS client 250 or 251. Through the interlocking units 220 and 221, a series of information related to the configuration or performance of each network element 210 and 211, information related to a failure or alarm, and the like are received and stored in a database.

For example, each EMS client 250 or 251 provides a user interface as shown in the example of FIG. 6 when the system user attempts to log in to access the element management system. A system using a particular EMS client 250 when the management service of the environment is selected and an error occurs in the MS server 240 during operation according to the management service of the client-server environment. By enabling the user to select and switch to a stand-alone environment when the user attempts to log in again, the server program is executed in the MS client 250 by the selection of the stand-alone environment, and thus a server thread. Through the EMS client 250 in a stand-alone environment It will play a role.

Here, the user interface includes a selection button for selecting a client-server environment or a stand-alone environment, and an input window for inputting an IP address of an EMS server according to the client-server environment.

On the other hand, the operation of the control method of the element management system supporting a plurality of operating environments of the present invention will be described.

In FIG. 2, it is assumed that a system user accesses the element management system using the EMS client 250, wherein the system user may select either a client-server environment or a stand-alone environment. It is assumed that a system user operates the MS client 250 in a stand-alone environment due to an error of the EMS server 240 while operating in a server environment.

First, in the present invention, when the system user wants to access the element management system using the EMS client 250, the EMS client 250, on the user interface that supports the login, as shown in FIG. Support the selection button to select any one of a client-server environment or a stand-alone environment, the management service through the selection button from the system user attempting to log in to the MS client 250 By selecting and executing a client program or a server program, it operates as a client in a client-server environment or as a server in a stand-alone environment.

That is, when a system user attempts to log in to the element management system using the EMS client 250 (S30), the EMS client 250 displays a user interface for selecting a management service as shown in FIG. By selecting the execution environment from the system administrator by activating (S31) and operating in a client-server environment or a stand-alone environment according to the selected execution environment, a plurality of network elements (210,211) through each device interworking unit (220,221) Operation control and management (S32).

In this case, when the system user selects the client-server environment, the IP address of the EMS server 240 to be accessed should be input to the input window on the user interface. However, when the system user selects the stand-alone environment, the MS client Since the 250 itself serves as a server, it is not necessary to separately input the IP address of the EMS server 240.

In this case, when the element management system to which the present invention is applied is operated in a client-server environment, as shown in the conceptual diagram of FIG. 4, the client 300 and the middle ware client 310 are one processor as the MS client 250 and 251. And the server 400 and the middleware server 410 are mounted on the MS server 240 as one processor, and operate as a client program that drives the client thread. The server 300 operates as a server program that drives a thread. After the client 300 logs in to the server 400, the middleware client 310 and the middleware server are connected through a network 500 (LAN). 410 is connected to transmit and receive data between the server 400 and the client 300.

That is, when the client-server environment is selected through the user interface, upon logging in from the client program of the EMS client 250, the login to the EMS server 240 is performed according to the client-server environment, and the EMS server 240 is performed. ) And the EMS client 250 are separate workstations or PCs, and the protocol for connecting the EMS server 240 and the EMS client 250 is CORBA, RMI, TCP / IP, or the like.

Therefore, the EMS client 250 accesses the EMS server 240 upon login and is notified of the success of the login. When the login is successful, the EMS client 250 registers itself with the EMS server 240 and the EMS It is possible to receive various events from the server 240, the EMS client 250 transmits all the commands to each network element (210, 211) through the EMS server 240, and vice versa All responses from (210, 211) are transmitted to the MS client 250 through the MS server 240.

On the other hand, after the step (S32), the element management system according to the assumption of the present invention, while operating in the client-server environment, the error occurs in the EMS server 240 to control and manage each network element 210 If it is not possible (S34), the EMS client 250 requests a retry of the login, when the system user retries the login, through the user interface for selecting the management service as in step S30 The stand-affected environment is selected (S35).

Then, the EMS client 250 executes a server program mounted therein according to the selected stand-alone environment to drive a server thread, thereby standing-in on behalf of the failed MS server 240. It operates as a server in an adverse environment, that is, without performing an operation for connecting to the EMS server 240, without access to the EMS server 240, to the element management system according to the operation of the server thread. Collecting and storing information on a series of information, faults, and alarms related to the configuration or performance of each connected network element (210,211) and storing them in a stand-alone data database (260) and operating the system, That is, it performs the role of a server in a client-server environment (S36).

In this case, when the element management system to which the present invention is applied is operated in a stand-alone environment, both the client program and the server program are mounted in one processor, and the client 300 and the server 400 are composed of respective threads. In the MS client 250 which is coupled and operated, the sub-program is executed and the server thread is operated. Thus, the middleware client 310 and the middleware server 410 do not operate as shown in the conceptual diagram of FIG. 5. Instead, the server 400, which is a server program performing the same function as the server program in a stand-alone environment, is directly connected to the client 300 in the EMS client 250.

That is, when the stand-over environment is selected through the user interface, upon logging in the server program of the EMS client 250, the EMS server 240 located elsewhere using an IP address according to the stand-alone environment By operating a server thread by performing a login using an internal server program without accessing the system, when a system user issues a command from the MS client 250, the system user is transferred to the network elements 210 and 211 through the server thread. Responses of the network elements 210 and 211 are transmitted back to the MS client 250 through the server thread.

Therefore, when the operation is performed in step S36, the MS client 250 can directly control and manage the network elements 210 and 211. In this case, the stand is due to an error in the client-server environment. -While the transition to an adverse environment has been described, it is also possible to switch to a client-server environment through a user interface for login while operating the element management system 20 to 22 in a stand-alone environment.

As described above, the present invention configures the programs of the client-server environment and the stand-alone environment into one program and is mounted on one processor, that is, the EMS client 250, thereby providing element management systems 20-22. By selecting the operating environment when logging in), it can be set to operate in a client-server environment in the case of a large network according to the size of the network configuration, and to operate in a stand-alone environment in a small network.

As described above, the present invention provides a client-operation step in a user logging in to an element management system in operating and managing a network element through an element management system (EMS). Operate the system through the server according to the user's convenience (for example, the size of the network configuration) by operating the element management system by selecting the server (Client-Server) or the stand-alone environment. It is possible to decide whether to run the system directly or in stand-alone state, and even if a problem occurs in the server, stand-alone form directly on the client, independently of the server, It has the effect of making it possible to operate the system.
