Problems solved by technology

When considering the application scenario of Fiber To The Home (FTTH, Fiber To The Home), the ONU is user equipment, and the user can purchase and replace it by himself. Since the SN of such an ONU is not pre-stored in the SN library of the OLT, it is difficult for the operator If it is not credible, then such an ONU cannot be successfully registered and activated, and the support of the operator is required to open the service for such an ONU, which will not only bring troubles to the user, but also increase the operating cost of the operator

Embodiment 1

[0068] In this embodiment, the registration request type is SN and password registration request. The values ​​of each part of the allocation structure in the registration request sent by the OLT are: Alloc-ID = 254, bit 10 = 1 in the Flags field, StartTime = xx, StopTime = xx+25, that is, the upstream of the ONU in the allocation structure The transmission slot length is 26 bytes.

[0069]Because each PLOAMu message is 13 bytes, after receiving the above downlink frame, the registration information sent by the ONU to the OLT needs to include two PLOAMu messages, which are the PLOAMu message containing the SN, that is, the SN message (Serial_Number_ONU message), and the PLOAMu message containing the password. The PLOAMu message, that is, the password message (Password Message), if the ONU does not have a password, the password message carries an invalid password, such as 0.

[0070] After the ONU in the serial number state receives the above registration request from the OLT,...

Embodiment 2

[0074] In this embodiment, the registration request type is SN or password registration request. The values ​​of each part of the allocation structure in the registration request sent by the OLT are: Alloc-ID = 254, bit 10 = 1 in the Flags field, StartTime = xx, StopTime = xx+12, that is, the upstream of the ONU in the allocation structure The transmission slot length is 13 bytes.

[0075] Because each PLOAMu message is 13 bytes, after receiving the above downlink frame, the ONU needs to send 1 PLOAMu message to the OLT.

[0076] After receiving the above registration request, the ONU checks the relevant local information, and if there is password information, then sends the password message to the OLT, otherwise sends the SN message to the OLT. After receiving the password message or SN message sent by the ONU, the OLT authenticates it. If the password or SN of the ONU is stored in the OLT, the OLT assigns and sends a unique ONU_ID to the ONU, and the ONU that obtains the ON...

Embodiment 3

[0078] The OLT uses different types of registration requests to allow ONUs to register in batches, reducing the probability of conflicts when multiple ONUs register.

[0079] Differentiate the type of registration request and define two kinds of registration requests used by OLT to discover unregistered and activated ONUs, namely SN registration request (Registering_Request_SN) and password registration request (Registering_Request_Password), which correspond to two types of allocations for discovering no registered and activated ONUs structure. The OLT will send these two types of registration requests in turn at a certain period. The ONU registered with the SN sends the SN information to register after receiving the SN registration request; the ONU registered with the password sends the password information to register after receiving the password registration request.

[0080] In the allocation structure of the registration request sent by the OLT, bits 6-0 of the Flags are...

Abstract

The invention provides an optical network unit (ONU) registration activating method. In the method, an ONU of a serial number state is used for receiving a registration request transmitted by an optical line terminal (OLT), confirming the type of the registration request and then transmitting corresponding registration information to the OLT; the OLT is used for judging whether the ONU is legal or not according to the received registration information of the ONU; if the ONU is legal, the OLT is used for distributing and transmitting a unique ONU mark to the ONU; after receiving the ONU mark, the ONU enters a distance measuring state and enters a working state after receiving equalized delay transmitted by the OLT, and the ONU registering activation is successful; and if the ONU is illegal, the ONU registering activation is failed. The invention also provides an ONU registration activating system which comprises an ONU and an OLT. The method and the system of the invention can realize the successful registering activation of the ONU when a serial number of the legal ONU is not stored in the OLT.

Description

technical field [0001] The present invention relates to the field of optical access network communication, in particular to a method and system for registering and activating an Optical Network Unit (ONU, Optical Network Unit) in a Gigabit Passive Optical Network (GPON, Gigabit Passive Optical Network) system. Background technique [0002] With the development of network technology, the network can be used to transmit a large amount of voice, data, video, etc., so the requirements for network bandwidth continue to increase, and GPON is produced under this demand. The GPON system usually consists of an Optical Line Terminal (OLT, Optical Line Terminal) on the network side, an ONU on the user side, and an Optical Distribution Network (ODN, Optical Distribution Network), and generally adopts a point-to-multipoint network structure. Among them, ODN is composed of passive optical devices such as single-mode optical fibers, optical splitters, and optical connectors, and provides o...
