BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to common maintenance commands / messages in a multi-vendor compatible communication device.

[0002]

2. Description of the Related Art A network is constructed by a plurality of communication devices (communication nodes), and each communication node transmits the received data information and voice information to a corresponding transmission path, thereby making a terminal device such as a mobile terminal. Communication between them takes place. The operation / maintenance of the network constructed by a plurality of communication nodes is performed based on the maintenance / operation information in each communication node. Maintenance / operation information is information in each communication node for maintaining / operating the network.For example, service-related traffic information such as the number of accesses from a customer for a certain service, and which service a certain subscriber subscribes to. Subscriber information such as availability, device fault information, etc.

In operation and maintenance, a maintenance person inputs a maintenance command to the operation system, the operation system sends a maintenance command to the communication node, and the communication node collects maintenance and operation information in accordance with the maintenance command.
The communication node transmits the maintenance / operation information to the operation system, the operation system receives the maintenance / operation information and displays it on the display, and the maintenance person confirms the maintenance / operation information. In many cases, a plurality of communication nodes that make up a network are provided by a plurality of vendors.

FIG. 8 is a diagram showing a network composed of nodes of a plurality of vendors. As shown in FIG.
The network is an operation system 2, nodes 4 # A1-4 # A3 manufactured by company A, and nodes 4 # B1, 4 # manufactured by company B.
It is composed of B2 and node 4 # C1 manufactured by C company. If the network consists of nodes from multiple vendors,
The maintainer uses the operation system 2 to execute maintenance commands based on different command systems for each vendor of A / B / C.
To enter. The operation system 2 transmits the input maintenance command to the corresponding node. The corresponding node is
When receiving the maintenance command addressed to its own node, it collects maintenance / operation information. Then, the message according to the message system unique to the vendor is transmitted to the operation system 2. The operation system 2 receives the message transmitted from the node and displays it on the display.
The maintenance person performs maintenance and operation of the network by analyzing the message for each vendor displayed on the display.

[0005]

However, the conventional network constructed by different vendors on different platforms has the following problems. Since the maintenance commands / messages were created by the vendor's own system, the maintainer should be aware of the different command / message systems for each vendor (A / B / C).
Since it is necessary to perform maintenance operation work by inputting maintenance commands and analyzing messages according to each node, it was easy to cause confusion in maintenance.

The present invention has been made in view of the above, and confusion caused by a command / message system different for each vendor, which occurs when maintaining and operating a network constructed by a platform of a plurality of different vendors, It is an object of the present invention to provide a node and a network that can be solved by making a command / message system common and can improve the efficiency of maintenance and operation.

The processing unit 20 is provided. Upon receiving the common format maintenance command transmitted from the operating system, the command receiving unit 10 outputs the maintenance command to the command control unit 14.
When the maintenance command is input, the command control unit 14
The command analysis unit 16 is instructed to analyze the command. The command analysis unit 16 determines whether the maintenance command is the first command related to vendor-specific processing or the second command related to vendor-specific processing, and notifies the command control unit 14 of the determination result.

The command control section 14 outputs the maintenance command to the first command processing section 18 if the maintenance command is the first command, and outputs the maintenance command to the second command processing section if the maintenance command is the second command. Output to 20. The first command processing unit 18 processes based on the first command to create a common format message. The second command processing unit 20 processes based on the second command to create a common format message. The command control unit 14 outputs the message in the common format created by the first and second command processing units 18 and 20 to the message transmission unit 12. The message transmission unit 12 transmits a common format message to the operation system. This allows
The operating system sends maintenance commands in a common format that is common to each vendor, not individual vendors, and receives messages that are in a common format that is common to each vendor, not individual vendors, so maintenance functions are unified and maintenance confusion occurs. It can be expected that the maintenance and operation efficiency will be improved.
