[0042] In this embodiment, the number of the maximum valid attributes in the MIB of an ONT in the GPON network is counted, that is, the number of attributes of the ONT that can be used by the OLT is confirmed. And correspondingly determine the data length of the effective attributes of each ONT that needs to be uploaded to the OLT, so that the ONT can encapsulate the effective attributes of each required injury into a message. Therefore, the message in this embodiment has different message lengths according to the data length of the effective attributes. Therefore, the previous fixed reporting method of each attribute is changed to improve the accuracy and efficiency of MIB reporting.
[0043] Therefore, in this embodiment, a mark AttrMask indicating whether the attribute is a valid attribute of the attribute required by the OLT is added to the attribute in the MIB, and the valid data length Len of the attribute is further marked in each valid attribute.

[0057] The difference between the MIB data upload method of this embodiment and the MIB data upload method of the first embodiment is that, in this embodiment, after the ONU receives the request message sent by the OLT, it generates all attributes of the MIB at that moment. Copy, that is, import all the attribute data in the MIB at that moment into a cache, so even if the attributes in the MIB change due to the configuration or function changes in the ONU, it will not change the attribute data uploaded by the ONU to the OLT. Avoid uploading data errors and invalid data.
[0058] Therefore, the MIB data upload method of this embodiment is as follows figure 2 As shown, including the following steps:
[0059] Step 11. The OLT sends an OMCI request message to an ONU.
[0060] Step 12: The ONU determines the preset upload attribute type based on the OMCI request message.
[0061] Step 13: Write all attributes of the current MIB of the ONU into a buffer. At this time, the ONU can write ...
