Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The described embodiments of the application are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art without making any inventive effort, are within the scope of the present application.
The network IP address of various decentralized intelligent devices, including mobile networking devices, is often obtained by dynamic acquisition, so the address of the communication node is mostly not fixed, and in particular, the IP address of the mobile device is a private IP address inside the lan of the mobile network node. From the centralized operation and maintenance center, each mobile terminal device cannot be actively accessed through the IP address of the public network. The operation and maintenance center is fixed, and the public network IP address of the operation and maintenance center is open for each intelligent device.
The intelligent communication equipment in the fixed local area network can be actively connected with the operation and maintenance center through the local area network route where the equipment is located. And the mobile network-based intelligent terminal equipment is connected to the network, and the IP address which is generally allocated to the mobile equipment is the local area network IP address which is allocated by the mobile base station, and belongs to private IP inside the local area network. The terminal device can actively connect with a remote operation and maintenance center server, and report the state of the terminal device to the operation and maintenance center server. The operation and maintenance center can remotely maintain the accessed terminal equipment.
The local area network or the mobile wireless network where various intelligent communication devices are located has uneven transmission signal quality of a communication link, and the reliability problem of maintenance instruction transmission exists during remote maintenance. Therefore, the application adopts the non-connection-oriented UDP protocol in the TCP/IP network protocol, and avoids the serious degradation of the performance of the operation and maintenance center caused by the poor transmission quality of part of communication links, thereby influencing the maintenance work of the whole system. The intelligent communication equipment adopts UDP protocol, accesses to wide area network through NAT protocol conversion of local area network, actively initiates communication connection to the operation and maintenance center, establishes remote maintenance link, and the operation and maintenance center can respond to message of remote equipment through the link and send maintenance command.
Based on the network characteristics, the application designs the remote maintenance technology as a passive monitoring maintenance technology. The operation and maintenance center deploys remote maintenance service and monitors the connection information of all the scattered intelligent communication devices. The name number of each intelligent communication device is uniformly arranged by an operation and maintenance center and is deployed in advance. After network connection, each mobile terminal device actively registers on-line to the operation and maintenance center through a gateway or a mobile base station of the local area network, and after the registration is successful, the maintenance instruction issued by the operation and maintenance center can be received and executed at any time.
In order to solve the complex and various characteristics of the remote maintenance object, a maintenance script technology is adopted to realize the remote maintenance work of each different communication device: all different intelligent communication devices adopt the same script file name, but the operation script file content of each different device can be different according to the characteristics of the device, and different remote maintenance script commands can be manufactured. The remote maintenance software includes a maintenance tool deployed at the operation and maintenance center, a remote maintenance service program of the operation and maintenance center, and client software running on each of the decentralized communication device terminals. The maintenance service and the client software of the communication device can be designed as generic software without having to pay attention to specific maintenance instructions of the different devices. The maintenance tool can design different management interfaces according to different types of intelligent equipment to manufacture corresponding remote maintenance command scripts. In the operation process, when the maintenance client program of the intelligent communication terminal receives the remote maintenance file, the maintenance script file with a unique appointed name is started and operated after decryption and decompression, and the maintenance script file is responsible for completing all maintenance commands to the equipment. The maintenance script is characterized in that the communication software and the intelligent equipment which are remotely maintained are decoupled, the communication software is universal, the communication software does not need to support maintenance instructions of the intelligent communication equipment of a specific type, and only needs to support starting and executing the total script file. The maintenance commands of different devices comprise maintenance commands such as information reading, log retrieval, configuration modification, software upgrading, network state diagnosis, hardware fault positioning and the like of the devices, the support is provided by the running software of the devices, and all the commands can be invoked through maintenance command scripts.

and 4, after the client program of the intelligent communication equipment completes all execution of the maintenance instruction sequence, the operation and maintenance center receives the successful or failed execution result obtained by the intelligent communication equipment according to the rules set in the maintenance script file.
The operation and maintenance center adopts a passive monitoring technology for the intelligent communication equipment, and can adapt to remote maintenance of various intelligent equipment connected with a network. The remote maintenance of the operation and maintenance center and the decentralized equipment adopts an encrypted UDP protocol. The maintenance script file adopts a unified entry script file name, a communication service program of the operation and maintenance center and a communication client program of the intelligent device, adopts a generalized design, and does not need to bind hardware devices with characteristics. The operation and maintenance center stores maintenance command sequences of each communication device by adopting an encrypted maintenance script for the maintenance commands of the intelligent communication device, wherein the commands comprise: information reading, log retrieval, configuration modification, software upgrading, network state diagnosis, hardware fault positioning and other maintenance commands for the equipment.
