from figure 2 It can be seen from the figure that there is a strong correlation between the previous and subsequent messages and the upgrade steps of the ONU/ONT itself. Once the timing of a certain message is out of order or a certain step is wrong, it will have an unpredictable impact on the entire upgrade process, and ev

Example Embodiment

[0044] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0045] The present invention realizes the protection method of abnormal situation in GPON terminal upgrade such as image 3 As shown, including the following steps:

[0046] Step 301: The ONU / ONT receives the End download command from the OLT, and the ONU / ONT ends the download and saves the version file.

[0047] Step 302: The ONU / ONT judges whether the downloaded version file is complete and correct. If it is complete and correct, it executes step 303 and responds that the OLT device is busy; if it is incomplete or incorrect, it responds to the OLT command processing error and ends the current processing flow .

[0048] Step 303: ONU / ONT prepares to burn the version file, start the programming program, and further judge whether the version file to be burned is valid, if it is valid, go to step 304; if it is invalid, end the programming process with the f...

Abstract

The invention discloses a protective method for abnormal situation in upgrading of a gigabit passive optical network (GPON) terminal, including the following steps: sequentially judging the integrity, correctness and validity of a new version of document downloaded to the GPON terminal and programming the new version of document; and determining verification of the new version according to the activating process of an OLT (Optical Line Terminal) to complete upgrading of the new version of the GPON terminal. Meanwhile, the invention also discloses a protective system for abnormal situation in upgrading of the GPON terminal. The method and the system can be adopted to improve the remote upgrading stability of the GPON terminal and then promote the maintainability and robustness of the GPON terminal system.
