[0062] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0063] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable in appropriate circumstances, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. "And / or" in the specification and claims represents at least one of the connected objects.

[0064] The existing GPON access network mainly includes OLT equipment and ONU equipment, among which the configuration, management and control of the ONU equipment are realized through the OMCI control module of the OLT equipment, and the OMCI control module is usually integrated in the manufacturer's equipment. Since the OLT equipment is implemented by different manufacturers, the implementation of the OMCI control module of different manufacturers may have inconsistent understanding of the standard, which leads to compatibility problems when the ONU equipment is connected to the OLT equipment of different manufacturers. In addition, the existing technology also has problems such as high equipment upgrade, maintenance and version unification costs and long upgrade cycle.

[0065] xGPON access network technology is evolving towards an SDN architecture with separated forwarding and control. It not only hopes to separate the management and control plane from the manufacturer's hardware equipment and realize a unified, open and centralized broadband access network management and control architecture, but also hopes to achieve rapid innovation and upgrading of broadband access technology.

[0066] Cloud-based and distributed xGPON access network ONU management and control systems will become a development trend. The current cloud-based and distributed ONU management and control systems still have the following problems:

[0067] 1. Failure to combine hardware processing capabilities to achieve reasonable control of ONU online access traffic leads to ONU control traffic congestion or even discarding.

[0068] 2. The gradual evolution requirements of different ONU device versions are not taken into account to implement access management for users of different versions.

[0069] 3. The ONU control and distribution path management is complex, including the complex management of multiple connections between multiple instances of each related entity and even MESH connections; the dynamic allocation of ONU control tasks is scattered across multiple entities, which makes management and maintenance complex.

[0070] The embodiment of the present invention realizes the distribution and management of ONU management and control tasks by introducing an ONU management and control agent system, which has the following advantages:

[0071] 1. Consider the hardware processing capability and implement ONU online access traffic control.

[0072] 2. Taking into account different ONU device versions, access management of users with different versions can be implemented.

[0073] 3. Access the ONU management and control task system through the proxy system. Since the ONU configuration process is stateful, it is necessary to correctly allocate the ONU management and control task requests and responses to the relevant management and control module (vOMCI) instances.

[0074] Figure 1 FIG. 1 is a schematic diagram of an architecture of an ONU control system according to an embodiment of the present invention. Figure 1 As shown, the ONU management and control system includes: a vOLT management and control system, a vOMCI system and an OLT device. In addition, the ONU management and control system may also include an EMS / SDN controller and an ONU device. Among them:

[0075] 1) The EMS / SDN control platform is mainly responsible for sending management and control task requests of the xGPON access network to the vOLT management and control system through the northbound interface;

[0076] 2) vOLT management and control system: mainly realizes the reception, analysis and processing of xGPON management requests from upper management system platforms such as EMS / SDN controllers, extracts and sends all ONU management and control processing requests to the vOMCI system;

[0077] 3) vOMCI system: The vOMCI system mainly includes two subsystems, namely the agent subsystem and the vOMCI subsystem. Among them, the agent subsystem is divided into two types, namely the ONU management agent subsystem and the vOMCI message agent subsystem, which are connected to the vOLT management and control system and the OLT system equipment on both sides of the vOMCI subsystem.

[0078] Specifically, the ONU management agent subsystem is connected to the vOLT management and control system. The subsystem is responsible for allocating specified vOMCI instances to different ONUs (any ONU can only be assigned to one vOMCI instance); the ONU management agent subsystem receives the ONU management and control processing request from the vOLT management and control system and distributes the request to the specified vOMCI instance, and returns the management and control processing result to the corresponding vOLT management and control system.

[0079] The vOMCI message proxy subsystem is on the OLT system device connection side. The vOMCI message proxy subsystem receives the OMCI request message of the OMCI control and processing request sent from the vOMCI instance to the ONU device, and sends the OMCI request message to the OLT device to which the ONU device is connected. At the same time, it is responsible for distributing the OMCI response message of the ONU device control and processing response received by the OLT to the specified vOMCI instance.

[0080] vOMCI subsystem: The vOMCI subsystem includes at least one vOMCI instance for processing ONU management and control tasks. Each vOMCI instance is responsible for receiving ONU management and control requests sent from the ONU management agent subsystem and performing ONU management and control tasks, including generating ONU device configuration sequences, synchronizing configuration libraries, etc. All configuration data is sent to the ONU of the corresponding OLT device through the vOMCI message agent subsystem via OMCI data packets. Finally, the execution results of the ONU device management and control tasks are reported to the vOLT management and control system through the ONU management agent subsystem.

[0081] 4) OLT device: Compared with the traditional OLT device, the OLT device of the embodiment of the present invention is also responsible for receiving the OMCI request message sent from the vOMCI message proxy subsystem and forwarding it to the ONU device, and returning the OMCI response message of the ONU management processing response to the vOMCI message proxy subsystem;

[0082] 5) ONU device: The ONU device of the embodiment of the present invention is similar to the traditional ONU device.

[0083] from Figure 1 As can be seen from the above, the vOMCI system of the embodiment of the present invention includes an ONU management agent subsystem, a vOMCI subsystem and a vOMCI message agent subsystem, wherein: the ONU management agent subsystem is connected to the vOLT management and control system and the vOMCI subsystem respectively; the vOMCI message agent subsystem is connected to the vOMCI subsystem and the OLT device respectively; the vOMCI subsystem includes at least one vOMCI instance, and each ONU corresponds to a vOMCI instance. Specifically:

[0086] Receive the ONU management and control response message sent by the target vOMCI instance, determine the target vOLT management and control instance remote service point name corresponding to the target ONU or the network connection identifier between the ONU management agent subsystem and the target vOLT management and control instance according to the identifier of the target ONU corresponding to the ONU management and control response message, and send the ONU management and control response message to the target vOLT management and control instance.

[0089] The target vOMCI instance is used to:

[0090] Receive an ONU control request message sent by the ONU management agent subsystem, perform an ONU control task, generate an OMCI request message carrying an identifier of the target ONU, and send the OMCI request message to the vOMCI message agent subsystem; and,

[0091] Receive the OMCI response message sent by the vOMCI message agent subsystem, generate an ONU management and control response message corresponding to the target ONU, and send the ONU management and control response message to the ONU management agent subsystem.

[0098] In an embodiment of the present invention, the ONU management agent subsystem maintains an ONU management and control processing task distribution table, as shown in Table 1, and each table item of the table records: the OUN identifier; the name of the remote service point of the vOLT management and control instance or the network connection identifier between the ONU management agent subsystem and the vOLT management and control instance; the name of the remote service point of the vOMCI instance or the network connection identifier between the ONU management agent subsystem and the vOMCI instance. That is, each line is an item, which records the correspondence between the ONU identifier, the name of the remote service point of the vOLT management and control instance or the network connection identifier between the ONU management agent subsystem and the vOLT management and control instance, and the name of the remote service point of the vOMCI instance or the network connection identifier between the ONU management agent subsystem and the vOMCI instance. A vOMCI instance usually has one or more vOMCI instance remote service points, and the name of the remote service point of the vOMCI instance is used to indicate a specific service point. Similarly, a vOLT management and control instance usually has one or more vOLT management and control instance remote service points, and the name of the remote service point of the vOLT management and control instance is used to indicate a specific service point.

[0107] The vOMCI message proxy subsystem is also used to search the vOMCI message distribution table according to the OUN identifier of the target ONU, determine the corresponding target OLT remote service point name of the OMCI request message of the target ONU or the network connection identifier between the vOMCI message proxy subsystem and the target OLT, and forward the vOMCI request message to the target OLT; and determine the corresponding target vOMCI instance remote service point name of the OMCI response message of the target ONU or the network connection identifier between the vOMCI message proxy subsystem and the target vOMCI instance, and forward the vOMCI response message to the target vOMCI instance; and determine the corresponding target vOMCI instance remote service point name of the OMCI active reporting message of the target ONU or the network connection identifier between the vOMCI message proxy subsystem and the target vOMCI instance, and forward the vOMCI active reporting message to the target vOMCI instance.

[0108] In an embodiment of the present invention, the ONU management agent subsystem is further used to search the ONU management and control processing task distribution table after receiving the ONU management and control request message. If the target vOMCI instance remote service point name corresponding to the target ONU or the network connection identifier between the ONU management agent subsystem and the target vOMCI instance is not found, the device manufacturer or version information of the target ONU is determined according to the target ONU identifier, and a corresponding vOMCI instance remote service point name or the network connection identifier between the ONU management agent subsystem and the vOMCI instance is assigned to the target ONU according to the association strategy, and the ONU management and control request message is sent to the assigned vOMCI instance, and the ONU management and control processing task forwarding table is added with the identifier of the OUN of the target ONU, the vOLT management and control instance remote service point name or the network connection identifier between the ONU management agent subsystem and the vOLT management and control instance, and the table entries of the assigned vOMCI instance remote service point name or the network connection identifier between the ONU management agent subsystem and the vOMCI instance.

[0109] Here, the association policy records the correspondence between the ONU and the remote service point name of the vOMCI instance or the network connection identifier between the ONU management agent subsystem and the vOMCI instance. The association policy may be pre-sent by the vOLT management and control system to the ONU management agent subsystem. Table 3 provides an example of an association policy. In addition, the remote service point name of the vOLT management and control instance or the network connection identifier between the ONU management agent subsystem and the vOLT management and control instance can be learned from the ONU management and control request message.

[0110]

[0111] Table 3

[0112] Similarly, the vOMCI message proxy subsystem can also maintain the vOMCI message distribution table in a similar manner. For example, the vOMCI message proxy subsystem receives the OMCI request message sent by the target vOMCI instance, searches the vOMCI message distribution table, and if no corresponding table entry is found, the vOMCI message proxy subsystem generates a corresponding entry for the ONU based on the pre-acquired remote service point name of the OLT device or the network connection identifier between the vOMCI message proxy subsystem and the OLT device.

[0113] The target ONU is assigned a corresponding OLT device remote service point name or a network connection identifier between the vOMCI message proxy subsystem and the OLT device, the OMCI request message is sent to the assigned OLT device, and the identifier of the OUN of the target ONU, the vOMCI instance remote service point name or the network connection identifier between the vOMCI message proxy subsystem and the vOMCI instance, and the table entry of the assigned OLT device remote service point name or the network connection identifier between the vOMCI message proxy subsystem and the OLT device are added to the vOMCI message distribution table. The vOMCI instance remote service point name or the network connection identifier between the vOMCI message proxy subsystem and the vOMCI instance can be learned from the OMCI request message.

[0114] In addition, the ONU management agent subsystem is also used to, after receiving the ONU control request message sent by the vOLT control instance, search the ONU control processing task distribution table according to the identifier of the target ONU carried in the ONU control request message, determine the vOLT control instance remote service point name corresponding to the target ONU or the network connection identifier between the ONU management agent subsystem and the vOLT control instance, and judge whether the vOLT control instance remote service point name corresponding to the target OUN or the network connection identifier between the ONU management agent subsystem and the vOLT control instance has changed according to the vOLT control instance remote service point name or the network connection that sends the ONU control request message. If changed, update the vOLT control instance remote service point name corresponding to the target ONU or the network connection identifier between the ONU management agent subsystem and the vOLT control instance in the ONU control processing task distribution table according to the vOLT control instance remote service point name or the network connection that sends the ONU control request message.

[0115] It can be seen that in the embodiment of the present invention, when the vOMCI proxy subsystem distributes the ONU control request and response between the vOLT control system and the vOMCI subsystem:

[0116] 1) The vOLT management and control system or its instance sends an ONU management and control request to the ONU management agent subsystem, which carries the ONU identifier and request information;

[0117] 2) The ONU management agent subsystem receives the ONU control request, checks the ONU control processing task distribution table (as shown in Table 1) according to the ONU identifier in the request message, and determines whether the ONU has been assigned a vOMCI task processing instance. If not, the specified vOMCI processing instance is assigned to the ONU according to the manufacturer identifier or version identifier in the ONU identifier, and the request is forwarded to the vOMCI task processing instance, and the ONU control processing task distribution table is updated, that is, the ONU identifier, the vOLT control system instance identifier or the network connection identifier between it and the vOMCI task processing instance identifier or the network connection connection identifier between it and the vOMCI task processing instance identifier is added to the table; if yes, the request is forwarded to the vOMCI task processing instance through the network service connection, and the vOLT control system instance connection is checked for changes. If yes, the vOLT control system instance identifier or the network connection identifier between it and the vOLT control system instance identifier in the ONU control processing task distribution table is updated;

[0118] 3) When the vOMCI instance completes the ONU control and processing request, a response message is generated, which carries the execution result, and the ONU identifier corresponding to the response message can be determined through the relevant low-level mechanism of the prior art. The response message is sent to the ONU management agent subsystem. The ONU management agent subsystem queries the ONU control and processing task distribution table, finds the corresponding vOLT control and processing system identifier or gRPC connection according to the ONU ID, and sends the ONU control and processing request response message to the vOLT control and management system or its instance through the connection;

[0119] 4) If a vOMCI instance is recreated or deleted during its life cycle when a failure occurs, the vOMCI proxy subsystem must update or delete the entry related to the vOMCI instance in the ONU control processing task distribution table.

[0120] When the vOMCI message proxy subsystem on the OLT system device side distributes OMCI message requests and responses between the vOMCI subsystem and the OLT system device:

[0121] 1) After the vOMCI instance receives the ONU control request and generates the OMCI message sequence, it sends the ONU identifier and OMCI message to the vOMCI message proxy subsystem on the OLT device side through the gRPC connection;

[0122] 2) After receiving the OMCI message request, the vOMCI message proxy subsystem on the OLT device side queries the connection identifier of the corresponding OLT device network service in the vOMCI message distribution table according to the ONU identifier carried by it, and sends it to the OLT device through the connection;

[0123] 3) After receiving the OMCI request message from the second subsystem, the OLT device forwards the OMCI message to the corresponding ONU device according to the ONU identifier; the OMCI response message received by the OLT device from the ONU device is returned to the vOMCI message proxy subsystem on the OLT system device side through the gRPC connection;

[0124] 4) After receiving the OMCI response message, the corresponding vOMCI network service connection identifier in the vOMCI message distribution table is queried according to the ONU identifier carried by the OMCI response message, and sent to the vOMCI instance through the connection.

[0125] In addition, in the embodiment of the present invention, the first / vOMCI message proxy subsystem needs to establish a connection with the relevant device in advance. Specifically:

[0126] The ONU management agent subsystem is also used to: establish a network connection between itself and the vOLT management and control system or the vOLT management and control instance, wherein the vOLT management and control system or the vOLT management and control instance is a client and the ONU management agent subsystem is a server; and establish a network connection between itself and the vOMCI instance, wherein the ONU management agent subsystem is a client and the vOMCI instance is a server. Here, the network connection can be a gRPC service connection, including but not limited to a gRPC protocol type, the same below.

[0127] The vOMCI message proxy subsystem is also used to: establish a network connection between itself and a vOMCI instance, wherein the vOMCI instance is a client and the vOMCI message proxy subsystem is a server; and establish a network connection between itself and an OLT, wherein the vOMCI message proxy subsystem is a client and the OLT is a server.

[0128] In the embodiment of the present invention, each ONU has an ONU identifier, which is shown in Table 4. Based on the ONU identifier, multiple information can be determined, mainly including at least one of the following information:

[0129] 1) Manufacturer identification of the OLT device to which the ONU belongs: used to identify the manufacturer of the OLT device to which the ONU device belongs;

[0130] 2) Device identification of the OLT device to which the ONU belongs: used to identify the OLT device identification to which the ONU device belongs;

[0131] 3) Board / slot identification of the OLT device to which the ONU belongs: used to identify the board identification in the OLT device to which the ONU device belongs;

[0132] 4) Identification of the OLT port to which the ONU is connected: used to identify the port identification on the board of the OLT device to which the ONU device belongs;

[0133] 5) ONU serial number: used to identify the serial number on the port of the ONU device;

[0134] 6) ONU version identification: used to identify the ONU device version.

[0135]

[0136] Table 4

[0137] The vOLT management and control system of the embodiment of the present invention is connected to the vOMCI system and at least one OLT respectively. Since each manufacturer's equipment usually has a limit on the parallel processing capability under the same OLT device port, that is, at most K ONU devices can be processed at the same time, K is a preset positive integer.

[0138] In an embodiment of the present invention, the vOLT management and control system is used to receive an online request of a first ONU reported by a first OLT, and determine, according to an identifier of an OLT port in an ONU identifier of the first ONU, whether the number of online ONUs currently being processed under the OLT port identifier reaches the maximum number supported by the OLT port:

[0139] If yes, then after waiting for a preset time, return to the step of determining whether the number of online ONUs currently being processed under the OLT port reaches the maximum number supported by the OLT port;

[0140] Otherwise, according to the online request, an ONU management and control request message carrying the ONU identifier of the first ONU is generated and sent to the vOMCI system.

[0141] In this way, after the vOLT management and control system of the embodiment of the present invention receives the ONU online request reported by the OLT device, it checks whether there are K online ONU devices being processed under the port according to the OLT port identifier in the ONU identifier. If so, it waits; if not, it sends the message to the vOMCI message agent subsystem on the vOLT management and control system side through the gRPC service connection.

[0142] In addition, the vOLT control system is also used to establish a connection between itself or a vOLT control system instance and an OLT device, wherein each OLT device is pre-assigned with a corresponding vOLT control system instance. The connection may be a gRPC service connection, including but not limited to a gRPC protocol type.

[0143] In an embodiment of the present invention, based on the ONU identifier, the following corresponding information of the ONU can be determined: the manufacturer identifier of the OLT device to which the ONU belongs, the device identifier of the OLT device to which the ONU belongs, the board / slot identifier of the OLT device to which the ONU belongs, the identifier of the OLT port to which the ONU is connected, the ONU serial number and the ONU version identifier; the vOLT management and control system is also used to send the ONU identifier and corresponding information to the ONU management agent subsystem.

[0144] The OLT device of the embodiment of the present invention is respectively connected to the vOMCI system and at least one ONU. The OLT is used to receive an OMCI request message carrying an identifier of a target ONU sent by the vOMCI system, and forward the OMCI request message to the target ONU according to the identifier of the target ONU; and receive an OMCI request response or an active reporting message sent by the target ONU, and send the OMCI request response or the active reporting message to the vOMCI system.

[0145] From the above, it can be seen that the embodiment of the present invention realizes the decoupling of ONU and OLT devices through the vOMCI system, including independent and rapid upgrade of ONU device characteristics, etc. In addition, the embodiment of the present invention also provides a unified and standard OMCI software plug-in or public service platform, which greatly reduces the interoperability problem of ONU and OLT devices, reduces the complexity of multi-vendor PON management and control, gradually forms the next generation of broadband access equipment management and control interface, promotes the realization of unified and standard programmable architecture of PON equipment, realizes flexible upgrade of PON access equipment and minimizes upgrade costs.
