Method of management information communication in communication network and memory device for storing a conversion program of management information between network center and switching nodes
First Claim
1. A method of management information communication between a network management system center called as a manager, which manages the communication network according to a Common Management Information Protocol (CMIP), and at least one switching node called as an agent which is managed by the manager, comprising the steps of:
- transmitting, a management instruction sentence composed of a transfer syntax in accordance with an algorithm based on ITU-T recommendation from the network management system center to at least a specified switching node;
converting the management instruction sentence formed according to the transfer syntax to an abstract syntactic sentence composed of parameters of a CMIS which is regulated within the management information communication system, at the specified switching node on receiving the management instruction sent from the network management center;
converting said abstract syntactic sentence to a format of Graphic User Interface (GUI) corresponding to an existing application software;
transferring said GUI to said application software;
converting GUI expressed sentences of an execution result of said application software, an event occurred in the switching node, and a state change to an abstract syntactic sentences; and
converting the abstract syntactic sentences to transfer syntax and transmitting the transfer syntax to said network management system center.

Abstract
A management information communication apparatus provided on an switching node side, which is used for a management information communication between a network management system center which is provided on a management side of a network management system in a communication network according to a Common Management Information Protocol (CMIP), and an switching node to be managed so called as an agent. This apparatus comprises a transfer syntax/abstract syntax conversion section for converting an instruction sentence formed of a transfer syntax to an abstract syntax composed of CMIS parameters; an abstract syntactic sentence/GUI conversion section for converting the abstract syntactic sentence to a Graphic User Interface (GUI) corresponding to an existing application software; a GUI/abstract syntactic sentence conversion section for converting the GUI expressed report such as an execution result of the application software corresponding to the GUI, an event occurred, and a state change in an switching node; an abstract syntax/transfer syntax conversion section for converting the abstract syntax to a transfer syntax; a CMIS/CMIP execution processing section for transferring the transfer syntax to the network management system center; and an OSI control section for interfacing to the manager.

2. A management information communication apparatus provided at a switching node for a management information communication between a network management system center called as a manager, which is provided for managing a network management system in a communication network according to a Common Management Information Protocol (CMIP), and at least one switching node called as an agent which is managed by the manager, said apparatus comprising:
-
a transfer syntax/abstract syntax conversion means for converting a received instruction sentence composed of transfer syntax according to an algorithm regulated by an ITU-T recommendation to an abstract syntax composed of parameters of a CMIS which is defined in the network management system; abstract syntax/GUI conversion means for converting said abstract syntactic sentence to a format of Graphic User Interface (GUI) corresponding to an existing application software; GUI/abstract syntax conversion means for converting GUI expressed reports, namely a result of execution of the application software corresponding to said instruction, an event and a state change occurred within the switching node; abstract syntax/transfer syntax conversion means for converting said abstract syntactic sentences to a transfer syntax; and means for transmitting said transfer syntax to the network management system center.

3. A recording medium provided for a switching node thereat, said recording medium stores a program of a method of management information communication between a network management system center called as a manager which is provided for managing a network management system according to a Common Management Information Protocol (CMIP) and at least one switching node called as an agent which is managed by the manager, wherein the recording medium stores, at least one of following conversion programs for a management information communication:
-
a transfer syntax/abstract syntax conversion processing routine for converting an instruction sentence composed of a transfer syntax received from a manager, to an abstract syntax composed of parameters of Common Management Information Service (CMIS); an abstract syntactic sentence/GUI conversion processing routine for converting the abstract syntactic sentence composed of the CMIS parameters to a format of Graphic User Interface (GUI) corresponding to application software for maintenance of an switching node; a GUI/abstract syntax conversion processing routine for converting a GUI expressed reports namely an execution result of the said application software, events and state changes occurred in the switching node to a abstract syntactic sentences; and
an abstract syntax/transfer syntax conversion processing routine for converting an abstract syntactic sentence to a transfer syntax for a transmission to the manager.
