Abstract

PROBLEM TO BE SOLVED: To shorten the development period for following up specification alterations of network element(NE) control commands by referring to a database and sending a command of optimum system version to an NE when an operator inputs a control command of a communication device. SOLUTION: When the operator performs control with commands, a system file version deciding process part 7 retrieves and obtains the system file version of an NE to be controlled with the commands from a database of a system file version management part 8. With this system file version, command translating process parts 4 and 5 corresponding to versions A and B to be started are decided. A command distributing process part 6 selects one of the interfaces of the command translating process parts 4 and 5 according to the decision result. Then the commands that the operator inputs are generated or translated by the command translating process parts 4 and 5 to fed the commands to the NE through a communication control part 3.

2. Description of the Related Art A network operation system that performs a wide area aggregation of NEs manages a plurality of NEs. However, NE file updates accompanying the addition of new NE services are not performed to all NEs at the same time. Network operation system is new and old 2 when file is updated
It is necessary to manage a network in which the NE system versions of the generations are mixed. In order to cope with this, in the network operation system, when developing the file of the operation system corresponding to the new and old NE file version numbers, it is necessary to be able to cope with the old NE file. For this reason, in the control command processing unit that processes the control command to the NE, when remodeling the processing unit according to the change in the specification of the NE control command accompanying the addition of a new service of the NE, the N having the old system file is used.
E and E have been designed and manufactured to guarantee compatibility of old and new commands so that control commands can be input.

As described above, in order to follow a change in the specification of a command accompanying the addition of a new service of the NE, if a change is made to an existing control command processing section, the control command processing section after the change performs a test of the new version control command. At the same time, the old version of the control command must be tested, and the test operation associated with the command specification change requires twice the number of specification changes, which has been a factor of lengthening the development period.
