Embodiment 1

[0046] Take OAM setting ONU parameters as an example, such as figure 1 As shown, the traditional OLT configuration ONU process is roughly divided into three steps:

[0047] Step 1: The ONU receives the OAM set message sent by the OLT;

[0048] Step 2: ONU parses the message, and passes the parameter to the relevant module to take effect, and finally saves the parameter to flash;

[0049] Step 3: The ONU replies the OAM set message of the OLT.

[0050] In the above process, whenever the user is offline or the device is restarted, the device will repeat the same process of sending and receiving configurations and taking effect, and save the received configurations to the flash, so as to erase and write the flash. Therefore, every time the user is offline or the device is restarted, the flash will be erased and written. However, as the number of such operations increases continuously, the service life of the flash will be continuously shortened, which will eventually affect th...

Embodiment 2

[0071] Based on the method for prolonging the flash life of the ONU terminal equipment described in Embodiment 1, this embodiment also provides a kind of ONU terminal equipment, including a receiving module, a first memory buffer module, a second memory buffer module, a comparison module, and a first analysis module. module, flash memory module flash, sending module;

[0072] The receiving module is configured to receive the OAM set message issued by the OLT;

[0073] The first memory buffer module is used to temporarily store the content of the OAM set message;

[0074] The second memory buffer module is used to temporarily store the content of the get message;

[0075] The comparison module is used to compare the content of the OAM set message with the content of the get message;

[0076] The first parsing module is used to parse the OAM set message, and provide the parameter value area part in the message to the memory buffer module for temporary storage; wherein, the mes...

Embodiment 3

[0086] A computer system includes a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program, the steps of the method are as follows:

[0087] S1: The ONU receives the OAM set message sent by the OLT;

[0088] S2: ONU temporarily stores the content of the OAM set message to the memory buffer buffer1;

[0089] S3: ONU invokes the get interface, and temporarily stores the content of the get message to the memory buffer buffer2;

[0090] S4: comparing the content of the OAM set message with the content of the get message; if the content of the message is not the same, then perform step S5; if the content of the message is the same, then perform step S6;

[0091] S5: The ONU parses the OAM set message, and passes the parsed parameters to the relevant module to take effect, and finally saves the parameters to flash;

[0092] S6: The ONU sends a response message to the OLT, thereby reducing the...

Abstract

The invention discloses a method for prolonging the service life of a flash of ONU terminal equipment and the ONU terminal equipment. The method comprises the following steps: S1, receiving an OAM set message issued by an OLT; S2, temporarily storing the content of the OAM set message in a memory buffer zone (buffer 1); S3, calling a get interface, and temporarily storing the content of a get message into a buffer 2 of the memory; S4, comparing the content of the OAM set message with the content of the get message, if the message contents are different, executing the step S5, and if the message contents are the same, executing the step S6; S5, analyzing the OAM set message, transmitting parameters obtained through analysis to a related module to take effect, and finally storing the parameters in a flash; and S6, sending a response message by the ONU to the OLT. According to the invention, the reading and comparison functions of the OLT issuing configuration parameters can be realized, the comparison result of the OLT issuing parameters and the ONU terminal parameters can be quickly and reliably obtained, unnecessary parameter effectiveness and flash read-write operation are avoided, the flash erasing frequency is reduced, and thus the service life of the flash is prolonged.

Description

technical field [0001] The present invention relates to the technical field of passive optical network, and more specifically, relates to a method for prolonging the flash life of ONU terminal equipment and the ONU terminal equipment. Background technique [0002] The PON (Passive Optical Network) includes an OLT (Optical Line Terminal) installed in the main control center, and a batch of supporting ONU (Optical Network Unit) terminal equipment installed in the user's place. There is a standard communication protocol between OLT and ONU, which is used by the main control center to configure, monitor and manage user terminal equipment, such as: OAM (Ethernet Operation, Management, Maintenance) and OMCI (ONT Management Control Interface), etc. . [0003] These communication protocols generally adopt the strategy of automatically going online to the OLT after the ONU is started. After the device registration process is completed, the OLT will automatically send the preset work...
