[0105] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0106] Figure 1 Schematic diagram of the system architecture of the ONU control method according to an embodiment of the present invention; Figure 1 As shown, the system may include: EMS / SDN controller, vOLT management and control function, virtualized ONU management system (vOMCI), OLT equipment and ONU equipment, etc. Among them:

[0107] The EMS / SDN controller is mainly responsible for sending management and control task requests for the xGPON access network to the vOLT management and control function.

[0108] The vOLT management and control function includes one or more vOLT management and control function instances, which receive, analyze, and process xGPON management requests from upper-layer management system platforms (such as EMS / SDN controllers), extract and send all ONU management request messages to the ONU management agent subsystem of the vOMCI system;

[0109] The vOMCI system includes: an ONU management agent subsystem and a vOMCI functional subsystem; or the vOMCI system includes: an ONU management agent subsystem, a vOMCI functional subsystem and a vOMCI message agent subsystem; wherein:

[0110] The ONU management agent subsystem is located between the vOLT control function and the vOMCI function subsystem and may include one or more ONU management agent instances. The ONU management agent instance receives ONU management requests from the vOLT control function instance and is responsible for allocating vOMCI function instances of corresponding versions to ONUs of different version types (one ONU can only be assigned to one vOMCI function instance). Different versions of vOMCI function instances can only serve ONU devices of corresponding version types and send the ONU management request to the vOMCI function instance. The ONU management agent instance is also responsible for returning the results of the management request processing to the same vOLT control function instance that manages the ONU; or sending notification reporting messages such as ONU alarms and events to the same vOLT control function instance that manages the ONU.

[0111] The vOMCI functional subsystem is located between the ONU management agent subsystem and the vOMCI message agent subsystem and may include one or more vOMCI functional instances (abbreviated as vOMCI instances in the figure). The vOMCI functional system supports the management of ONU devices of different types (e.g., different manufacturers, different versions). Different types of ONU devices have corresponding versions of vOMCI functional instance clusters for management. Each vOMCI functional instance is responsible for receiving ONU management requests sent from the ONU management agent instance, performing ONU management tasks (such as processing ONU management requests), including generating ONU device configuration sequences, synchronizing configuration libraries, generating corresponding vOMCI messages, and determining the appropriate vOMCI message agent instance to send the vOMCI request message to the OLT device to which the ONU device is connected, or directly to the OLT device to which the ONU device is connected; at the same time, it is responsible for receiving vOMCI request response messages or vOMCI notification reporting messages from the vOMCI message agent subsystem or OLT device, and converting them into ONU management request response messages or ONU notification reporting messages and sending them to the same ONU management agent instance that forwards the corresponding ONU management request message.

[0112] The vOMCI message proxy subsystem, located between the OLT and the vOMCI functional subsystem, can include one or more vOMCI message proxy instances. The vOMCI message proxy receives vOMCI message requests from the vOMCI functional instance responsible for ONU management, assigned by the ONU management agent, and sends these vOMCI messages to the ONU's OLT. The vOMCI message proxy also distributes ONU management response messages or notification event reporting messages received from the OLT to the same vOMCI functional instance responsible for ONU management.

[0113] The OLT device is mainly responsible for receiving vOMCI request messages sent from the vOMCI message proxy instance or vOMCI function instance and forwarding them to the ONU device. At the same time, it sends vOMCI request response messages or messages reported by the ONU to the same vOMCI function instance that forwarded the corresponding vOMCI request message.

[0114] The vOMCI message proxy subsystem in the vOMCI of this embodiment is an optional node device. The vOMCI function instance can be directly connected to the corresponding OLT device to transmit vOMCI request messages or vOMCI response messages, etc. through this connection; the vOMCI function instance can also determine a suitable vOMCI message proxy instance, that is, the vOMCI function instance is connected to the determined vOMCI message proxy instance, the vOMCI message proxy instance is connected to the corresponding OLT device, and the vOMCI request message or vOMCI response message, etc. are transmitted through the above two connections (that is, through forwarding of the vOMCI message proxy instance).

[0115] It should be noted that the various instances (Instance) in the embodiments of the present invention, such as the vOLT management and control function instance, the ONU management agent instance, the vOMCI function instance, the vOMCI message agent instance, etc., are a specific embodiment of the module. For the sake of convenience of description, those skilled in the art sometimes also refer to the "instance" as a "module", that is, the functions of the instance and the module are the same; wherein, a module can correspond to one instance or multiple instances.

[0119] The embodiments of the present application do not limit the names of the above-mentioned functions, systems, and instances, as long as the corresponding functions are implemented.

[0120] At least based on the above system architecture, the following embodiments of the present invention are proposed.

[0121] An embodiment of the present invention provides an ONU management and control method, which is applied to a vOLT management and control function, and specifically to a vOLT management and control function instance of the vOLT management and control function. Figure 2 The process diagram of the ONU control method according to the embodiment of the present invention is as follows Figure 1 ;like Figure 2 As shown, the method includes:

[0122] Step 101: A first vOLT control function instance of a vOLT control function receives an ONU management request message from an EMS / SDN controller; the first vOLT control function instance is a vOLT control function instance in the vOLT control function; the ONU management request message includes at least a first ONU identifier;

[0123] Step 102: The first vOLT management and control function instance sends the ONU management request message to the ONU management agent subsystem in the vOMCI.

[0124] In this embodiment, optionally, when the ONU device is online, the ONU device is connected to an OLT device, and the relevant information of the ONU device online is sent to the vOLT control function through the OLT device (such as Figure 1 The transmission path shown by the dotted line in FIG), that is, a vOLT control function instance in the vOLT control function (referred to as the first vOLT control function instance) receives information related to the online ONU device through the OLT device; wherein the information related to the online ONU device at least includes an identifier of the ONU device (referred to as the first ONU identifier here); optionally, the information related to the online ONU device may further include ONU device information, such as a device serial number, a software version number, etc. In this embodiment, the type of other information included in the information related to the online ONU device is not limited.

[0125] In this embodiment, after the first vOLT management and control function instance receives the ONU management request message from the EMS / SDN controller, it sends the ONU management request message to the ONU management agent subsystem in the vOMCI, where the ONU management request message includes at least the first ONU identifier.

[0126] In some optional embodiments, before the first vOLT management and control function instance sends the ONU management request message to the ONU management agent subsystem in the vOMCI, the method further includes: the first vOLT management and control function instance determines relevant information of a first ONU management agent instance based on the first ONU identifier, where the first ONU management agent instance is one of multiple ONU management agent instances in the ONU management agent subsystem;

[0127] Correspondingly, the first vOLT management and control function instance sends the ONU management request message to the ONU management agent subsystem in the vOMCI, including: the first vOLT management and control function instance sends the ONU management request message to the first ONU management agent instance based on the relevant information of the first ONU management agent instance.

[0128] In this embodiment, the first vOLT management and control function instance selects a suitable ONU management agent instance (referred to as a first ONU management agent instance) for the ONU device corresponding to the ONU management request message. The first ONU management agent instance corresponds to the first ONU identifier. The first vOLT management and control function instance determines the relevant information of the first ONU management agent instance based on the first ONU identifier, and then sends the first ONU management request message to the first ONU management agent instance based on the relevant information of the first ONU management agent instance.

[0129] Optionally, the first vOLT control function instance determines the relevant information of the first ONU management agent instance based on the first ONU identifier, including: the first vOLT control function instance determines the first vOMCI function instance version information corresponding to the first ONU identifier through a first correspondence; the first correspondence includes the correspondence between multiple groups of ONU identifiers and vOMCI function instance version information; the first vOLT control function instance determines the relevant information of the first ONU management agent instance corresponding to the first vOMCI function instance version information through a second correspondence; the second correspondence includes the correspondence between multiple groups of vOMCI function instance version information and the relevant information of the ONU management agent instance.

[0130] In this embodiment, on the one hand, the first corresponding relationship is maintained in the first vOLT management and control function instance. The first corresponding relationship is shown in Table 1, for example.

[0131] Table 1

[0132] ONU identification ONU device information (device serial number, software version, etc.) vOMCI function instance version ONU1 Onu12345678.NOKIA.V2.0 vOMCI2.1

[0133] On the other hand, each vOLT control function instance in the vOLT control function is configured with each ONU management agent instance information and its corresponding vOMCI function instance version information (i.e., the second correspondence relationship described above); alternatively, each vOLT control function instance in the vOLT control function queries each ONU management agent instance to obtain each ONU management agent instance information and its corresponding vOMCI function instance version information (i.e., the second correspondence relationship described above). For example, the second correspondence relationship described above is shown in Table 2.

[0134] Table 2

[0135]

[0136] Based on this, the first vOLT management and control function instance can query the first correspondence shown in Table 1 through the first ONU identifier to obtain the first vOMCI function instance version information corresponding to the first ONU identifier, and then query the second correspondence shown in Table 2 according to the first vOMCI function instance version information to obtain relevant information of the first ONU management agent instance corresponding to the first vOMCI function instance version.

[0137] The relevant information of the first ONU management agent instance may specifically be service access point information corresponding to the first ONU management agent instance. The service access point information corresponding to the first ONU management agent instance may specifically include at least one of a first ONU management agent service access point identifier, a first ONU management agent service access point address (such as an IP address and a port number), and a corresponding connection identifier.

[0138] In this embodiment, the first vOLT management and control function instance sends an ONU management request message to the first ONU management agent instance, where the ONU management request message includes at least the first ONU identifier; optionally, the ONU management request message may further include message parameters.

[0139] In some optional embodiments, after the first vOLT management and control function instance determines the relevant information of the first ONU management agent instance (e.g., the first ONU management agent service access point address), it establishes a connection with the first ONU management agent instance as needed, obtains the first ONU management agent service access point identifier, and records the first ONU management agent service access point identifier in the second correspondence shown in Table 2; or, if the first vOLT management and control function instance has already established a connection with the first ONU management agent instance, the first vOLT management and control function instance sends the first ONU management request message to the first ONU management agent instance through the established connection. The connection between the first vOLT management and control function instance and the first ONU management agent instance is a non-mesh connection, that is, a customized connection.

[0140] Optionally, the method further includes: the first vOLT control function instance recording a first forwarding relationship, where the first forwarding relationship includes a correspondence between the first ONU identifier and relevant information of the first ONU management agent instance.

[0141] In this embodiment, after determining the first ONU management agent instance corresponding to the ONU device, the first vOLT management function instance records the first ONU identifier and related information of the first ONU management agent instance in a first forwarding relationship. An example of the first forwarding relationship is shown in Table 3. Upon subsequently receiving an ONU management request message from the ONU device (corresponding to the first ONU identifier), the first vOLT management function instance only needs to forward the ONU management request message to the corresponding first ONU management agent instance according to the first forwarding relationship shown in Table 3.

[0142] Table 3

[0143] ONU identification Service access point or connection identifier (downstream) corresponding to the ONU management agent instance ONU1 ONUMgmtProxy1-endpoint-1-1 ONU2 ONUMgmtProxy2-endpoint-2-1 ONU3 ONUMgmtProxy3-endpoint-3-1

[0146] Optionally, the first vOLT control function instance can obtain relevant information of the first ONU management agent instance from the unified service point, that is, determine the first ONU management agent instance corresponding to the ONU device, and record the first ONU identifier and the relevant information of the first ONU management agent instance as the first forwarding relationship shown in Table 3.

In one embodiment, the first connection configuration information clarifies the specific static connection between nodes, that is, the first connection configuration information indicates the information of a specific ONU management agent instance, for example, vOLT control function instance 1 is connected to ONU management agent instance 1, etc., and this method is static. In another embodiment, the first connection configuration information indicates a connection strategy, for example, vOLT control function instance 1 is connected to a certain type of ONU management agent instance, that is, vOLT control function instance 1 and the ONU management agent instance of this type are connected in a meshed manner, etc.

[0151] Optionally, the connection between nodes can adopt the gRPC protocol, where one node is the client and the other node is the server. Of course, this embodiment is not limited to using the gRPC protocol to establish connections between nodes, and other protocol types can also be used.

[0157] Step 202: The first ONU management agent instance determines management chain path information between the first ONU management agent instance and the first OLT device based on the first ONU identifier, where the management chain path information includes path information between the first vOMCI function instance, path information between the first vOMCI function instance and the first vOMCI message agent instance, and path information between the first vOMCI message agent instance and the first OLT device. Alternatively, the management chain path information includes path information between the first vOMCI function instance and the path information between the first vOMCI function instance and the first OLT device.

[0158] Step 203: The first ONU management agent instance sends path configuration information related to the first vOMCI function instance, the first vOMCI message agent instance, and the first OLT device, respectively, to the first vOMCI function instance, the first vOMCI message agent instance, and the first OLT device based on the management chain path information; or, the first ONU management agent instance sends path configuration information related to the first vOMCI function instance and the first OLT device, respectively, to the first vOMCI function instance and the first OLT device, based on the management chain path information;

[0160] In some optional embodiments of the present invention, the first ONU management agent instance in the ONU management agent subsystem of the vOMCI receives the ONU management request message, including: the first ONU management agent instance directly receives the ONU management request message from the first vOLT management and control function instance; or, the unified service point in the ONU management agent subsystem receives the ONU management request message from the first vOLT management and control function instance, selects the first ONU management agent instance according to a preset strategy, and sends the ONU management request message to the first ONU management agent instance.

[0161] In this embodiment, based on the above embodiment, the first vOLT control function instance can send the ONU management request message via a non-mesh connection or a mesh connection. In one embodiment, the first vOLT control function instance obtains relevant information about the first ONU management agent instance, and can thereby directly send the ONU management request message to the first ONU management agent instance based on the relevant information about the first ONU management agent instance. In another embodiment, the first vOLT control function instance sends the ONU management request message to a unified service point. The unified service point can select the first ONU management agent instance according to a preset policy (e.g., a load balancing policy) and send the ONU management request message to the first ONU management agent instance.

The topology information may include connection configuration information for each node in the entire network, and each node may establish a connection with an adjacent node based on the corresponding connection configuration information; then, the first ONU management agent instance may determine the vOMCI function instance in the first vOMCI function instance set that can reach the first OLT device based on the topology information.

[0185] The first vOMCI function instance receives the ONU management request message, processes the ONU management request message, generates a vOMCI request message, and determines, based on the third forwarding relationship shown in Table 6, the relevant information of the first vOMCI message proxy instance of the next hop corresponding to the first ONU identifier, and sends the vOMCI request message to the first vOMCI message proxy instance based on the relevant information of the first vOMCI message proxy instance; or determines the relevant information of the first OLT device of the next hop corresponding to the first ONU identifier, and sends the vOMCI request message to the first OLT device based on the relevant information of the first OLT device.

[0194] In this embodiment, for a response (such as a vOMCI response message) or a notification (such as a vOMCI notification report message) fed back by an ONU device (such as the ONU device corresponding to the first ONU identifier), due to stateful processing requirements, the vOMCI response message or vOMCI notification report message must follow the same path as the ONU management request message. Each node then queries its managed forwarding relationship based on the first ONU identifier carried in the message, finds the relevant information of the corresponding upstream node, and sends the vOMCI response message or vOMCI notification report message to the corresponding upstream node based on the relevant information of the corresponding upstream node.

[0195] In some optional embodiments of the present invention, the first ONU management agent instance sends the path configuration information related to the first OLT device to the first OLT device based on the management chain path information, including: the first ONU management agent instance directly sends the path configuration information related to the first OLT device to the first OLT device; or, the first ONU management agent instance sends the management chain path information to the first vOLT management and control function instance, and the first management and control module is used to send the path configuration information related to the first OLT device to the first OLT device based on the management chain path information; wherein, the path configuration information related to the first OLT device includes the first ONU identifier, and the path configuration information related to the first OLT device also includes relevant information of the first vOMCI message agent instance or relevant information of the first vOMCI function instance.

Exemplarily, the path configuration information related to the first OLT device may be as shown in Table 8, and the path configuration information shown in Table 8 is recorded in the OLT device as the fifth forwarding relationship. It should be noted that Table 8 may include the relevant information of the vOMCI message agent instance shown in the second column or the relevant information of the vOMCI function instance shown in the third column.
