Problems solved by technology

However, even with variable-length OMCI messages, the OMCI message interaction between OLT and ONT is still "ping-pong"
Therefore, the OMCI configuration efficiency and OMCI channel bandwidth utilization of PON systems using variable-length OMCI messages are still low

Embodiment 1

[0033] The OMCI message transmission method provided by the embodiment of the present invention can be figure 2 implemented in the OLT of the PON system shown. see image 3 , the method may include:

[0034] 101. Group the OMCI messages to be sent according to whether there is a dependency relationship, wherein the OMCI messages in the same group have dependencies, and the OMCI messages between different groups have no dependencies;

[0035] 102. Determine the number of maximum concurrent OMCI messages currently supported between the OLT and the ONT;

[0036] 103. Search for groups that are in a state of not waiting for a response;

[0037] 104. When the number of OMCI messages that have been sent and are waiting for a response is less than the number of the maximum concurrent OMCI messages currently supported between the OLT and the ONT, obtain the OMCI message from the group in the state of not waiting for a response or waiting for a response and Send to ONT.

[0038] ...

Embodiment 2

[0042] The OMCI message transmission device provided by the embodiment of the present invention can be configured in figure 2 shown in the OLT of the PON system, see Figure 4 , the OMCI message transmission apparatus may include: a grouping unit 201 , a determining unit 202 , a searching unit 203 and a sending unit 204 .

[0043] Wherein, the grouping unit 201 is used to group the OMCI messages to be sent according to whether there is a dependency relationship, wherein the OMCI messages in the same group have dependencies, and the OMCI messages between different groups have no dependencies;

[0044] Determining unit 202, is used for determining the quantity of the maximum concurrent OMCI message currently supported between OLT and ONT;

[0045] A search unit 203, configured to search for packets in a state of not waiting for a response;

[0046] Sending unit 204, for when the quantity of the OMCI message that has been sent and waiting for response is less than the maximum ...

Embodiment 3

[0050] Based on the OMCI transmission method and transmission provided by the above-mentioned embodiments 1 and 2, the embodiment of the present invention further provides a PON system, and the PON system may be as follows figure 2 As shown, it includes: at least one OLT and a plurality of optical network terminals ONT, wherein the OLT is connected to the plurality of ONTs in a point-to-multipoint manner through ODN, and the OLT can send OMCI to the ONT message to implement the ONT for management and configuration.

[0051] Wherein, the OLT is used to group the OMCI messages to be sent according to whether there is a dependency relationship, so that the OMCI messages in the same group have dependency and the OMCI messages between different groups have no dependency; and, after sending and waiting When the quantity of the OMCI message of response is less than the maximum number of concurrent messages currently supported between the OLT and the ONT, obtain the OMCI message from...

Abstract

The invention provides an OMCI (Ont Management and Control Interface)message transmission method, a device and a passive optical network. The OMCI message transmission method includes dividing to-be-sent OMCI messages into groups, wherein OMCI messages in a same group have dependence and OMCI messages in different groups have no dependence; determining a maximum number of concurrent OMCI messagessupported between an OLT and ONT; according to the maximum number of concurrent OMCI messages supported between an OLT and ONT, acquiring OMCI messages from groups that not waiting for response and sending to the ONT.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an optical network terminal management and control interface (ONT Management and Control Interface, OMCI) message transmission method, device and passive optical network (Passive Optical Network, PON) system. Background technique [0002] The passive optical network system is mainly composed of OLT (Optical Line Terminal), ODN (Optical Distribution Network) and ONT (Optical Network Terminal). In GPON (Gigabit Passive Optical Network) / 10GPON (10 Gigabit Passive Optical Network), OLT uses OMCI protocol to manage and configure ONT. According to the definition of the existing OMCI protocol, the way of transmitting OMCI messages between OLT and ONT is "ping-pong", such as figure 1 As shown, after receiving the OMCI message (OMCI Message) sent by the OLT, the ONT returns the corresponding OMCI Response Message (OMCI Response Message) to the OLT. When the OLT receives th...
