In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Before explaining this application, here is an explanation of the technologies related to FTTR in the related art:

[0039] FTTR is a new coverage model for home and small office or home office (SOHO) office networks in the Gigabit era. It is based on Fiber To The Building (FTTB) in the 10M era and Fiber To The Home (FTTH) in the 100M era, and further extends the fiber optic layout to every room or office, so that every room or office can reach Gigabit fiber optic network speed, realizing a new networking solution with full coverage of wireless fidelity (Wi-Fi) 6 Gigabit throughout the house.

[0040] The home Gigabit all-optical networking solution based on FTTR technology deploys the main optical modem in the home distribution box or the center of the home. With the main optical modem as the core, it adopts point-to-multipoint (P2MP) / point-to-point (P2P) mode, based on splitters and single-core bidirectional optical fibers, to build a home optical fiber network. FTTR replaces network cables with optical fibers, allowing optical fibers to go from "to the home" to "rooms", solving the bottleneck of home network wiring in one step. Optical fiber is recognized as the fastest signal transmission medium and does not need to be upgraded after deployment; optical fiber products are mature and low-priced, which can save deployment costs; optical fiber has a long service life; transparent optical fiber can be used without damaging home decoration and aesthetics, etc.

[0041] The FTTR network consists of a master optical modem (master ONU), a slave optical modem (slave ONU), and an ODN. Here, the FTTR network can include a master optical modem and an unlimited number of slave optical modems. The master optical modem and the slave optical modems can be connected by wire (such as optical fiber) or wirelessly, so that the master optical modem and the slave optical modems can communicate with each other, and the slave optical modems are placed in each room to complete the construction process of the whole house FTTR network. In the FTTR network, the slave optical modem can synchronize the wireless network parameter configuration of the master optical modem.

[0042] Figure 1 is a topology diagram of a two-level P2MP network provided in the related art; Figure 1 As shown, the first-level P2MP network includes OLT and a master gateway; the second-level P2MP network includes a master gateway and multiple slave gateways; the first-level P2MP network is an FTTH optical network; the second-level P2MP network is an FTTR optical network; the OLT communicates with the master gateway through the first-level P2MP optical line interface; the master gateway communicates with multiple slave gateways through the second-level P2MP optical line interface; the slave gateway communicates with the terminal equipment (such as UE, base station) through the user side interface; the master gateway includes an uplink optical port and a downlink optical port.

[0043] Figure 2 is a schematic diagram of a communication module of a two-level P2MP network provided in the related art; Figure 2As shown, the OLT includes an SFU optical network unit management and control interface (ONU Management and Control Interface, OMCI) module, a gigabit media access controller (GMAC) and an MFU OMCI module; the MFU includes a GMAC, an MFU OMCI module and an SFU management interface. Each SFU (such as SFU#1, ..., SFU#N) includes an SFU management module. The SFU management module communicates with each SFU through a master-slave optical layer interface; the communication message format between the SFU OMCI module and the SFU management interface is the OMCI message format; the communication message format between the MFU OMCI module in the OLT and the MFU OMCI module in the MFU is the G.988OMCI message format.

[0044] Here, OMCI is a protocol for information exchange between OLT and ONT defined in the standard, and is used for OLT management of ONT in GPON network, including configuration management, fault management, performance management and security management.

[0045] It should be noted that the master gateway serves as both the terminal device of the OLT and the "OLT" of the slave device, and needs to have the ability to manage the slave devices.

[0046] Figure 3 A flowchart of an information synchronization method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method is applied to a P2MP cascade optical communication system, and the information synchronization method includes:

[0047] Step 301: An optical gateway device sends a first message to a first device.

[0048] Among them, the optical gateway device includes the second device or the third device; there is a master-slave relationship between the first device and the second device, and the first device is the master device of the second device; there is a master-slave relationship between the second device and the third device, and the second device is the master device of the third device.

[0049] In the embodiment of the present application, the architecture of the P2MP cascade optical communication system provided by the present application is a 2-level P2MP network cascade, and the uplink communication of the first-level P2MP system and the second-level P2MP system both adopts a time division multiple access (TDMA) mechanism. Here, the first device includes an optical line terminal device on the first-level P2MP system; the second device includes a master gateway device on the first-level P2MP system; and the third device includes a slave gateway device on the second-level P2MP system.

[0050] In the embodiment of the present application, the third device sends the first message to the first device through the second device.

[0051] In an embodiment of the present application, the first device supports dual management information bases between the first device and the second device and between the first device and the third device; for example, the first device, i.e., the OLT on the first-level P2MP system, stores an OLT-SFU management information base (MIB) library and an OLT-MFU MIB library.

[0052] In the embodiment of the present application, the third device supports dual management information bases between the first device and the second device and between the first device and the third device; for example, the third device, namely the SFU on the second-level P2MP system, stores the OLT-SFU MIB library and the OLT-MFU MIB library.

[0053] In the embodiment of the present application, the first message is sent in the following ways: in-band, out-of-band, media, signaling, data, message, control plane, user plane, etc. Among them, the first message can be sent through an existing interface to better be compatible with the existing system and reduce the cost of system transformation. In addition, when multi-party communication is performed, the established media plane communication channel is a one-to-many multicast / broadcast communication channel, so that the first message is sent only once through the established multicast / broadcast communication channel, and the first device can receive it, effectively reducing the number of messages sent.

[0054] In an embodiment of the present application, the first message may be a request message for requesting configuration or update of the first device. It may be generated by the second device and sent to the first device, or it may be generated by a third device and sent to the first device via the second device.

[0055] Exemplarily, the first message is a message requesting the OLT to configure the MFU and / or SFU.

[0056] Step 302: The first device receives a first message generated by the optical gateway device.

[0057] In the embodiment of the present application, the optical gateway device sends a first message generated by itself to the first device. Accordingly, after receiving the first message, the first device determines whether to perform configuration, such as information synchronization, based on the first message. If configuration is required, after synchronizing its own target management library, the second message is sent to the optical gateway device to instruct the optical gateway device to synchronize the management library. If no configuration is required, the current interaction process can be stopped after directly parsing and processing the first message.

[0058] In the embodiment of the present application, the first message may be sent directly from the SFU to the OLT, or may be forwarded to the corresponding OLT via the MFU.

[0059] Step 303: The first device parses and processes the first message to obtain relevant synchronization information.

[0060] In the embodiment of the present application, the relevant synchronization information may be the relevant configuration parameters requested by the optical gateway device obtained after the first device parses and processes the first message, and then the first device determines the information that needs to be synchronized based on the relevant configuration parameters.

[0061] In an embodiment of the present application, the relevant synchronization information includes one or more of the following information: alarm information of the first device and / or the optical gateway device; an optical module alarm threshold of the third device; a device serial number (sequence number, SN) of the first device and / or the optical gateway device; the distance of the optical fiber between the first device and the optical gateway device; and an identification of the first device and / or the optical gateway device.

[0062] In the embodiment of the present application, the identifier of the third device is the SFU ID. The SFU ID can be SFU#n, where n belongs to {1, 2, ..., N}, and N is an integer greater than 0. The SFU ID can be generated by the OLT and assigned to the SFU, for example: the OLT generates the SFU ID and then assigns it to the main device MFU, and then the MFU assigns it to the SFU hanging on demand. Alternatively, the identifier of the SFU can be generated by the MFU and then assigned to the SFU, for example: the MFU generates the SFU ID and then assigns it to the SFU hanging on demand.

[0063] Step 304: The first device updates the relevant synchronization information to the target management information base between the first device and the optical gateway device.

[0064] In the embodiment of the present application, the target management information base includes a first management information base between the second device and the first device, and a second management information base between the third device and the first device.

[0065] In an embodiment of the present application, the first management information base supports full or partial extension of the optical network unit management control interface protocol stack function; the overlapping part of the protocol stack function corresponding to the first management information base and the second management information base is managed by the first device or the second device; wherein the first management information base is located on the first device, and records information between the first device and the third device; the second management information base is located on the second device, and records information between the third device and the second device; the target management information base includes the first management information base.

[0066] In the embodiment of the present application, the first information management library includes the alarm information between the second device and the first device; the alarm threshold of the optical module of the third device; the device SN of the first device; the device SN of the third device; the distance of the optical fiber between the first device and the third device, etc. The second information management library includes the alarm information between the third device and the first device; the alarm threshold of the optical module of the third device; the device SN of the second device; the device SN of the third device; the distance of the optical fiber between the second device and the third device, etc.

[0067] The embodiment of the present application discloses an information synchronization method, which includes: an optical gateway device sends a first message to a first device; wherein the optical gateway device includes a second device or a third device; there is a master-slave relationship between the first device and the second device, the first device is the master device of the second device, and there is a master-slave relationship between the second device and the third device, the second device is the master device of the third device; the first device receives the first message generated by the optical gateway device; the first device parses and processes the first message to obtain relevant synchronization information; and updates the relevant synchronization information to the target management information library between the first device and the optical gateway device. In other words, the present application implements configuration between the first device (such as OLT) and the optical gateway device (such as SFU and MFU) through messages, such as information synchronization; for example, the SFU requests the OLT to perform information synchronization through the first message, that is, the OLT updates the target management information library between the OLT and the SFU with the relevant synchronization information, or the MFU requests the OLT to perform information synchronization through the first message, that is, the OLT updates the target management information library between the OLT and the MFU with the relevant synchronization information, which solves the problem that the OLT cannot configure the SFU in a related technology, resulting in insufficient network capacity, and greatly improves the network capacity.

[0068] The present application proposes a MIB synchronization mechanism for a point-to-multipoint cascade optical communication system, which supports OLT / MFU to dynamically configure SFU respectively and avoid conflicts, thereby greatly enhancing network capabilities.

[0069] In some embodiments, the method provided in the embodiments of the present application includes the following contents:

[0070] Step A1: The first device sends a second message to the optical gateway device.

[0071] The second message includes relevant synchronization information; the second message is used to update or manage the optical gateway device and records the management information base of the information between the optical gateway device and the first device.

[0072] Here, the second message is one of the following: optical layer operation and maintenance message; management message of the first device for the optical gateway device; extended optical network unit management and control interface message; optical network unit management and control interface message; for example, OMCI / Enhanced (Enhanced, e) OMCI management message for processing OLT and MFU, and OMCI / Enhanced (Enhanced, e) OMCI management message for processing OLT and SFU.

[0073] In the embodiment of the present application, the second message may be sent directly from the OLT to the SFU, or may be forwarded to the corresponding SFU via the MFU.

[0074] In the embodiment of the present application, the management message may also be referred to as a direct management message, which may be understood as a direct management message between the OLT and the SFU, or a direct management message between the OLT and the MFU. The structure of the management message conforms to a preset format, and may be generated based on the optical network unit management and control interface (OMCI) message format defined in the present solution, and may be referred to as an OMCI message.

[0075] In an embodiment of the present application, the second message is a link between the first device and the second device, multiplexing the optical network unit management control channel between the first device and the second device; and / or the second message is a link between the second device and the third device, multiplexing the optical network unit management control channel or the fiber-to-room management control channel between the second device and the third device.

[0076] Step A2: The optical gateway device receives the second message sent by the first device.

[0077] In the embodiment of the present application, the third device receives the second message sent by the first device through the second device.

[0078] In an embodiment of the present application, a management information base synchronization message between the second device and the third device is transmitted through an optical network unit management control channel or a fiber-to-room management control channel between the second device and the third device to achieve better compatibility with the existing system and reduce the cost of system transformation.

[0079] Through the solution in the embodiment of the present application, the OLT can directly manage the SFU, thereby avoiding the risks caused by the MFU agent managing the SFU, achieving efficient management of the SFU, and improving the reliability and stability of the FTTR system. In addition, by directly managing the SFU by the OLT, the telecom-level control capability can be extended to the home, improving the user experience.

[0080] under, Figure 4 is a schematic block diagram of a P2MP cascade optical communication system provided by an embodiment of the present application in an actual application scenario; Figure 4 As shown, the OLT includes OMCI-MFU and OMCI-SFU. The MFU includes OMCI-Client, Adapter and FMCI-Server. The SFU includes FTTR Management and Control Interface (FMCI)-Client and eOMCI-Client. The communication data between OMCI-MFU and OMCI-Client is transmitted through the Enhanced Optical Network Unit Management and Control Channel (eOMCC), the communication data between OMCI-SFU and OMCI-Client is transmitted through the eOMCC, and the communication data between FMCI-Server and FMCI-Client is transmitted through the FTTR Management and Control Channel (FMCC).

[0081] It should be noted that the P2MP cascade optical communication system architecture is a two-level P2MP network cascade, and the uplink communications of the first-level and second-level P2MP systems both adopt the TDMA mechanism.

[0082] The OLT device in the first-level P2MP system can directly manage the OLT-SFU MIB library on the SFU device. The SFU supports the MFU-SFU and OLT-SFU dual MIB libraries, and the OLT supports the OLT-MFU and OLT-SFU dual MIB libraries.

[0083] It should be noted that the module composition and functions of OLT, MFU and SFU are as follows:

[0084] Here, the OLT supports the following functions:

[0085] OMCI MFU: processes OMCI / eOMCI management messages between OLT and MFU.

[0086] OMCI SFU: processes OMCI / eOMCI management messages between OLT and SFU.

[0087] Here, the following functions are supported for MFU:

[0088] OMCI / eOMCI Client: Receives eOMCI management messages from the OLT, identifies the SFU eOMCI messages sent by the OLT, and forwards them to the Adapter.

[0089] Adapter: parses the eOMCI message from OLT to MFU and converts it into Passive Optical Network (PON) MAC configuration, such as Transmission Container (T-CONT) and GEM-Port configuration. Sends the eOMCI message from OLT to SFU to OMCI / FMCI Server.

[0090] OMCI / FMCI Sever: Generates OMCI / FMCI messages between FTTR master and slave devices; forwards eOMCI messages between OLT and SFU

[0091] Here, the following functions are supported for SFU:

[0092] OMCI / FMCI Client: Receives OMCI / FMCI management messages from MFU to SFU; forwards eOMCI messages between OLT and SFU.

[0093] eOMCI Client: Receives eOMCI management messages from OLT to SFU;

[0094] It should be noted that OLT-SFU supports avoiding configuration conflicts.

[0095] Exemplarily: SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold, device SN, and fiber distance. OLT and SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold, device SN, and fiber distance. OLT and MFU MIB synchronization also includes: alarm synchronization, SFU optical module alarm threshold, device SN, and fiber distance.

[0096] The alarm synchronization and SFU optical module alarm threshold are managed by the OLT; the equipment SN and optical fiber distance are managed by the SFU.

[0097] Exemplarily: SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold, device SN, fiber distance. OLT and SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold. OLT and MFU MIB synchronization includes: device SN, fiber distance.

[0098] Exemplarily: SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold, device SN, fiber distance. OLT and SFU MIB synchronization includes: alarm synchronization, SFU optical module alarm threshold, device SN. OLT and MFU MIB synchronization includes: device SN, fiber distance.

[0099] It should be noted that the MIB library synchronization between the OLT and the SFU is based on the optical layer operation, administration, maintenance (OAM) or direct management message or eOMCI message or extended OMCI message transmission between the OLT and the SFU.

[0100] It should be noted that, in the link between OLT and MFU, this message can reuse the OMCC channel between OLT and MFU; in the link between MFU and SFU, it can reuse the OMCC or FMCC channel between MFU and SFU.

[0101] It should be noted that, for the MIB synchronization message between the OLT and the SFU, the MFU identifies and directly transparently transmits it to the SFU or the OLT.

[0102] It should be noted that the MIB synchronization message between the MFU and the SFU is transmitted through the OMCC or FMCC channel between the MFU and the SFU.
