Background technique

The operator has defined the optical network unit (Optical Network Unit, ONU) for the remote application (Application, abbreviated as APP). The following uses the terminal as a mobile phone as an example: the specified ONU and mobile APP pass The interface connection channel interacts with the remote platform. Under normal circumstances, this method is really convenient and easy to maintain. However, in most cases, the Interface connection channel will not work in the event of a fault; or the heartbeat of the mobile app communication link cannot be maintained, causing a malfunction, which may cause it to work normally; if it is necessary to troubleshoot the fault, it will be troublesome. Of course, it is also possible to use the mobile phone to access the ONU's IEEE 802.11b-based wireless local area network (WiFi) to operate the ONU. In this case, the ONU needs to have the wifi access function, or the maintenance personnel bring their own access point (Access Point, referred to as AP) access, and this processing method must be entered into the user's home to operate, and it is cumbersome to enter the user's home when the fault occurs, and the processing efficiency is very low.

The present invention will be described below by taking the above terminal as a smart phone device as an example. It can be seen from the foregoing embodiment that, in order to facilitate state detection and troubleshooting of the remote ONU, an alternate channel is provided, and the ONU is managed by the management channel in the PON network through the smart phone device. With this method, as long as the optical network terminal ONU establishes a management channel with the OLT, the ONU can be managed remotely through the smart terminal. When the remote communication link of the mobile APP is faulty, you can quickly switch to the alternate channel, query the current running status and main parameters of the ONU, analyze the cause of the fault, and quickly locate the problem. After troubleshooting, it is also convenient to switch to the normal communication link.

The following describes how to manage the ONU by using a smart phone. The management process includes the following steps:

Step A: Add support for the universal exchange format on the optical network unit (ONU); such as JSON (java Script Object notation, is a lightweight data exchange format), protocol cache protocol buffer, thrift (a software framework) For development of scalable and cross-language services, etc.

Step A also includes defining a common data exchange format common to the ONU and the APP side. The content contained in the universal format is determined according to actual needs, but needs to have a basic format, such as a message type, a message sequence number, a command type, and a message status. Configuration content, etc.

The ONU needs to support the data of the universal switching format to be transmitted through the management channel of the ONU. For the Ethernet Passive Optical Network (EPON) product, the extended OAM mode is adopted.

Step B: Establish a management channel of the OLT and the optical network unit (ONU) for carrying the general data exchange format generated in step A.

In step B, the definition of the frame format common to the ONU and the OLT is also included, and the management channel is implemented by using the frame format. The frame format is used to carry a common data exchange format to implement data interaction between the remote intelligent terminal and the ONU.

The OLT also needs to provide an external interface for other platforms to receive content generated by the ONU side in a common data exchange format. The OLT itself does not perform any processing on the general interaction data and directly transmits it to the remote service management platform.

Step C: Providing a remote service management platform, the remote intelligent terminal manages and operates the ONU through the platform. When the normal interface connection channel fails, the link switches to the remote service platform, and the intelligent terminal operation mode of the management channel is adopted.

The intelligent terminal can implement the operation and maintenance of the ONU by performing the following steps, that is, managing the OUN.

Step 1: Configure the IP address of the remote service platform on the smart terminal. When the intelligent terminal detects the remote ONU failure, the intelligent terminal switches to the remote service platform according to the configured IP address.

Step 2: The smart terminal sends a command to bind to the ONU of the terminal. The command is transmitted in the general data exchange format in step A, and the content carried is the SN information of the ONU.

Step 3: The remote service management platform connects to the OLT through a protocol such as Simple Network Management Protocol (SNMP), and invokes the interface of the common data interaction format provided by the OLT in step B.

Step 4: After the binding message is transparently transmitted to the ONU through the OLT, the ONU decodes the general data interaction content, and after verifying the password, sends the result to the intelligent terminal.

Step 5: After the binding is successful, the standby channel enters the normal configuration mode, and the intelligent terminal can configure and query the ONU.

The interaction process between the intelligent terminal and the ONU should not conflict with the interaction process of the extended OAM itself. That is to say, each message of the intelligent terminal and the ONU should carry a unique identification code, and each packet of data is processed by using a unique identification code.

The common universal data format of the intelligent terminal and the ONU may adopt a format defined in the telecommunication specification, or may negotiate a new format as needed.

Step D: After the normal Interface connection channel is restored, the connection channel between the intelligent terminal and the ONU Switch to the Interface connection channel.

Steps for the intelligent terminal to switch back to the normal operation channel:

Step 1: The unbinding command is sent to the ONU through the smart terminal, and the command is encapsulated in a common data format.

Step 2: After receiving the unbinding message sent by the intelligent terminal, the ONU returns an operation success message to the intelligent terminal, and closes the connection channel of the intelligent terminal.

Step 3: The intelligent terminal exits the standby channel management mode and switches to the normal Interface connection channel to operate the intelligent terminal.
