Abstract

PURPOSE: A command interface method between an NMS(Network Management System) and an NE(Network Element) in a TMN(Telecommunication Management Network) is provided to execute necessary commands through NEs and to receive an execution result, without new GDMO(Guidelines for Definition of Managed Objects) definition for each managed object and correction work in a network element, by defining a command interface management object so as to execute a management function for an NE not comprised in a managed object. CONSTITUTION: A network management center inputs a command string to be executed in an NE to an operation and maintenance center through a user interface(30). The inputted command string is converted into the action information argument of action information for an m-action operation(32). The operation and maintenance center transfers the m-action operation to a network management agent(34). If the m-action is executed, the measurement of a reply time for the operation is started(36). the network management agent confirms whether a timer value exceeds a threshold for the m-action(38). In case that the timer value doesn't exceed the threshold, a result for the m-action is received from the network management agent(40). A command execution result is extracted from the received result. The reply data are displayed on the user interface screen(44). If the timer value doesn't exceed the threshold, an error message is displayed on the user interface screen(42).

It consists of a function of notifying the upper network administrator of the test result information.

The present invention provides an upper network administrator through a communication management network Q3 interface between a base station management system, which is a network element constituting a personal communication system (PCS), a switching center system, a home location register, and a network management center. A method of sending an operation command to a network element and receiving the result, FIG. 2 shows a system configuration diagram of a communication management network according to the present invention. As shown, the management agent 22 included in the intermediate apparatus 20 is Q3 matching 18 with the operation maintenance center 16 and the network element 26 through the gateway 24. .

3 is a flowchart illustrating a method of performing an operation command to a network element through a management agent in an operation maintenance center according to the present invention. In the network management center, a command to be executed in a network element is input through a user interface (30). . The received command string is recorded 32 in ActionArg of action information of action factor for performing m-action of ITU-T Recommendation X.711. The ActionArgument is transmitted 34 to a management agent through a communication management network by a higher network manager. When the m-action is performed, measurement of the response time for the operation is initiated 36 and a check is made to see if a timer value exceeds the threshold for the m-action (38). After checking whether or not the threshold value for the m-action is exceeded, it is checked whether the result is received (40). When the result for the m-action is successfully received by the upper network manager through the management agent, the response data is used. 44 is displayed on the interface screen. However, if the timer value exceeds the threshold time value, the user interface screen displays that an error has occurred (42).

Referring to FIG. 4, the network management agent receives 46 the m-action operation of the upper manager of the network management center, and the network management agent receives a network element from an action factor of action information in the received action operation. Extract 48 the command string to be executed. The command string is extracted 48, and the network management agent forwards the command string 50 to the operations management processor of the network element through the gateway of the network management agent. The operation management processor checks whether the transmitted command string has a grammatical error and transmits the test result to the network management agent, and the network management agent receives 52 the test result. The network management agent receiving the test result determines 54 whether the syntax check result is a success or a failure. If the syntax check result of the command sent to the network element by the network management agent is successful, whether the type of the command is a test command or a future statistical command that cannot immediately receive the result is compared with a list stored in the memory. Decision 56 is made. If the type of command is not a delay response command, a timer for measuring a response delay time at the network element for the command is started (58), and whether or not a result of the command performed from the network element is received. Determine (60). If the determination result is a delayed response command, since a response cannot be received within the threshold time of the timer, information 62 indicating that the command was successfully received is sent to the action response to send an action result to the network manager. Since the response to the command has been successfully received, input 64 to the action response of the action result with the result information. In operation 66, it is determined whether a timer value for determining a case in which a response to a command due to a problem in the network device is not exceeded exceeds a threshold value. When the timer times out after the threshold time, the error information is input to the action response of the action result in order to report the information that the timeout for the command has occurred in the network element to the upper manager. . The response to the m-action is transmitted including the already created action factor.

Referring to FIG. 5, when a command requested by a network management center is a test command or future statistics that cannot be responded to within a threshold time of a timer by a network agent in a network element, a test result or a result of statistical measurement is received after a syntax check response. (72). The event information EventInfo of the Event Report Argument is constructed 74 from the received response data, and an m-incident notification is transmitted 76 to the upper manager, including the already created Event Notification Factor.

While the invention is susceptible to various modifications and alternative forms, the disclosure thereof has been described with reference to specific embodiments only. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the specification, but rather that the invention is intended to cover all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
