Problems solved by technology

On the other hand, the on-site configuration data also needs to be configured with different addresses according to the requirements of different sites. It is necessary to prepare device configuration scripts in advance. The preparation work is complicated and error-prone. For a large number of devices, the labor cost of this method is relatively high.
However, there is still no automatic maintenance communication method for small-sized devices such as MDUs, so as to facilitate the management and configuration of these small-sized devices

Embodiment 1

[0049] This embodiment provides a method for automatically establishing a management and maintenance channel between a network manager and a user-side device. This method can be used in a network such as a passive optical network (PON) (see image 3 ), to automatically open the management and maintenance channel of the user-side equipment, so as to configure and commission the user-side equipment through the network management equipment at the local end, and realize its free soft-tuning. This method is as follows: Figure 5 shown, including:

[0050] Step 11, increase user-side equipment on the network management equipment at the central office, namely the network management equipment at the central office specifies configuration information for the OLT equipment and the user-side equipment, and reserves maintenance channel resources; wherein, the configuration information includes the OLT equipment (optical line The first configuration information of the terminal) and the sec...

Embodiment 2

[0073] like Figure 7 As shown, there are actually multiple user-side devices, and multiple user-side devices are used in a multi-level cascading state. For instructions, see the specific steps to get through Figure 8 :

[0074] Step 21, the network management equipment at the central office designates configuration information (including the first configuration information for the OLT equipment of the optical line terminal and the second configuration information for the user side equipment, and reserves maintenance channel resources;

[0075] Step 22, the OLT equipment at the central office interacts with the user-side equipment through a corresponding layer-2 protocol, specifically by the last-level equipment at the user-side to the first-level equipment (directly with the central office OLT equipment) through the intermediate-level equipment The connected user-side device) sends a bridge protocol data unit BPDU message; the first-level device encapsulates the received B...

Embodiment 3

[0091] like Figure 9 As shown, this embodiment provides a device 101 for establishing a management and maintenance channel. The device can be used at the central office as an optical line terminal to interact with user-side equipment to automatically open a network management maintenance channel for managing user-side equipment, specifically including:

[0092] An information receiving module 102, configured to receive configuration information issued by the network management device;

[0093] The maintenance channel establishment module 103 creates a management and maintenance channel with the network management device according to the first configuration information in the configuration information;

[0094] The information sending module 104 is communicatively connected with the information receiving module, and sends the second configuration information for the user side device in the configuration information received by the information receiving module to the user side ...

Abstract

The invention discloses a method, a device and a system for building a management and maintenance channel in a passive optical network system. The method of the invention comprises the following steps: configuration information transmitted by a network management equipment is received, and the configuration information comprises a first configuration information and a second configuration information; according to the first configuration information, a management and maintenance channel between an optical line terminal and the network management equipment is built; the second configuration information is transmitted to a customer premises equipment; and the second configuration information is used for building a management and maintenance channel between the optical line terminal and the customer premises equipment. The method lowers soft cost for installing equipment, lowers complexity of installing new equipment, improves customer satisfaction, needs no on-site data configuration, reduces the probability of configuration data errors and improves equipment installation speed; in addition, the method is simple to replace equipment, needs no on-site re-configuration of data, and reduces maintenance cost.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a method, device and system for automatically establishing a management and maintenance channel between a network manager and user-side equipment in a passive optical network system. Background technique [0002] Passive Optical Network (PON, Passive Optical Network) is a single-fiber bidirectional optical access network that adopts a point-to-multipoint (P2MP) structure. Its typical topology is a tree type, such as figure 1 As shown, the passive optical splitter can be one-stage optical splitter or multi-stage optical splitter. [0003] With the development of PON technology, the application mode of Fiber To The Home / Fiber To The Building (FTTH / FTTB, Fiber To The Home / Fiber To The Building) is becoming more and more mature. Taking Ethernet Passive Optical Network (EPON) as an example: [0004] For FTTH application mode, the terminal usually adopts Optical Network Terminal (...
