Detailed ways

In order to make the purpose, technical methods and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that in the flowchart.

The present application provides a service processing method and apparatus, an OLT device, and a computer-readable storage medium. The service processing method of one embodiment is applied to an emergency OLT, and the method includes: in the event of a service failure in the ONU under the target OLT, registering the ONU; connecting the network access device through a wireless network so that service data is transmitted between the network access device and the ONU based on the emergency OLT. In this embodiment, in the event of a service failure in the ONU under the target OLT, compared with the manual recovery of the service in the related technology, an emergency OLT is used to re-hang and register the ONU, and the network access device is connected through a wireless network so that service data is transmitted between the network access device and the ONU based on the emergency OLT, thereby reducing the recovery time of the ONU device service failure, further improving the recovery efficiency of the ONU device service failure, and thus filling the technical gap in the related methods.

The embodiments of the present application are further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a service processing device provided by an embodiment of the present application. The service processing device includes but is not limited to an emergency OLT 111 and a customer premises equipment (Customer Premises Equipment, CPE) 112. CPE 112 is connected to the emergency OLT 111.

In the event of a service failure in ONU 120, such as a trunk optical fiber breakage of the target OLT corresponding to ONU 120, emergency OLT 111 is used to register ONU 120 under the target OLT, that is, to complete the registration of ONU 120 according to the received registration information, and the registration information is sent by ONU 120 to emergency OLT 111 when ONU 120 is under the emergency OLT 111, wherein "under the emergency OLT 111" is used to characterize the functional correspondence, that is, ONU 120 is under the emergency OLT 111, indicating that ONU 120 needs to go through the emergency OLT 111 to implement specific functions.

CPE112 is used to provide a wireless network to the emergency OLT111, so that the emergency OLT111 is connected to the network access device 130 through the wireless network, and then the network access device 130 and the ONU120 are used to transmit service data based on the emergency OLT111, which can reduce the recovery time of the service failure of the ONU120 and further improve the recovery efficiency of the service failure of the ONU120. The wireless network is used to build a VPN channel, and the VPN channel is used by the emergency OLT111 to realize the service recovery of the registered ONU120. It should be noted that service recovery means that various services of the ONU can operate normally, including but not limited to services such as Internet access;

The network access device 130 is used to transmit service data with the ONU 120 based on the emergency OLT 111, that is, it can be but not limited to receiving the authentication information of the ONU 120 sent by the emergency OLT 111 through the VPN channel, and authenticating the ONU 120 according to the authentication information of the ONU 120, and allocating an IP address to the authenticated ONU 120 to achieve service recovery of the authenticated ONU 120. In other words, the quality of interaction between the network access device 130 and the emergency OLT 111 can be improved through the VPN channel, and the actual downstream available bandwidth can be greatly improved, thereby meeting the needs of the network access device 130 for service recovery of the ONU 120.

In the event of a service failure in ONU120, compared with the manual service recovery in the related art, the emergency OLT111 in the emergency equipment is used to re-hang the ONU120, and the ONU120 is registered through the emergency OLT111, and a wireless network for building a VPN channel is provided to the emergency OLT111 through the CPE112, so that the service recovery of ONU120 can be further achieved through the cooperation of the VPN channel and the emergency OLT111, thereby reducing the recovery time of the service failure of the ONU120 device, further improving the recovery efficiency of the service failure of the ONU120 device, and thus filling the technical gap in the related methods; it has been verified that the recovery time of the ONU120 service can be shortened from 2 to 3 hours to about 15 minutes, thereby greatly improving the efficiency of the ONU120 service recovery.

It should be noted that there may be multiple situations when ONU120 encounters a service failure. For example, when ONU120 attached to the target OLT encounters a service failure, the emergency OLT111 replaces the target OLT and reattaches ONU120. This is not limited here and requires specific analysis in specific situations. For example, a common situation is that the trunk optical fiber corresponding to the PON optical fiber interface of the target OLT in the passive optical network PON is broken, that is, the trunk optical fiber of the target OLT connected to the corresponding optical splitter is interrupted, and the optical splitter is further connected to ONU120, so this will cause the service of ONU120 to be interrupted and form a service failure; for example, ONU120 cannot match the target OLT so that ONU120 cannot be well managed, resulting in a service failure of ONU120, etc., that is, ONU120 itself may have problems that cause service failures.

In one embodiment, the types and parameters of the emergency OLT 111 and the target OLT are not limited. The emergency OLT 111 is equivalent to a backup OLT for the target OLT, so that when a problem occurs in the target OLT, the emergency OLT 111 can be used to configure the ONU 120, thereby solving the problem of service failure of the ONU 120 in this case; moreover, ONU devices from different manufacturers can be supported for application, and the specific application scenario is not limited here.

In one embodiment, the specific form and content of the registration information and authentication information sent by ONU120 are not limited. For example, the authentication message can be but not limited to the user broadband account username, password and other authentication messages, which can be set according to the specific application scenario and will not be elaborated here.

In one embodiment, the specific manner in which the emergency OLT 111 completes the registration of the ONU 120 according to the received registration information is not limited, and those skilled in the art can set it according to the actual application scenario. For example, by pre-configuring the plug-and-play (PNP) function on the emergency OLT 111, the plug-and-play of the ONU 120 on the emergency OLT 111 is realized, which improves the usability and greatly reduces the requirements for the skills of the operator. That is, the emergency OLT 111 can be used, but not limited to, to detect the serial number of the ONU 120 according to the received registration information, and replace the pre-configured target serial number with the detected serial number of the ONU 120, and complete the registration of the ONU 120 according to the target serial number. That is to say, by pre-configuring the corresponding target serial number, when the ONU 120 is accessed, the pre-configured target serial number can be replaced with the detected serial number of the ONU 120 according to the registration information sent by the ONU 120. The serial number of the ONU120 is replaced with the serial number of the ONU120, thereby realizing the plug-and-play function. This configuration method is more suitable for emergency OLT111 with standardized data. For example, the ONU120 service cutover can also be realized with the help of the network management. This function is more suitable for emergency OLT111 with less standardized data. That is, the emergency OLT111 can be used, but not limited to, to find the serial number of the ONU120 and the data configuration corresponding to the serial number from the pre-configured or predetermined network management according to the received registration information, and complete the ONU120 registration according to the configuration instruction and the serial number of the ONU120 when receiving the configuration instruction from the network management. That is to say, by finding the ONU120 corresponding to the network management The corresponding serial number and the data configuration corresponding to the serial number are configured so that the corresponding serial number and the corresponding data configuration are configured for ONU120 according to the configuration instruction of the network management.

In one embodiment, the specific type of the network access device 130 is not limited and can be selected according to the actual scenario. For example, in order to integrate 5G and fixed-line broadband services, the network access device 130 can be set as a broadband access server (Broadband Remote Access Server, BRAS); for another example, in a wireless network access scenario, the network access device 130 can be, but is not limited to, set as a corresponding network device.

In one embodiment, CPE112 can be connected to an external wireless network to facilitate the establishment of a VPN channel between the emergency OLT111 and the network access device 130 through the wireless network. The VPN channel in this case ensures good communication between the emergency OLT111 and the network access device 130. That is to say, it can not only provide an emergency OLT111 for re-hanging ONU120, but also provide a corresponding VPN channel to further realize the service recovery of ONU120. By improving the VPN channel service, the actual downstream available bandwidth can be greatly improved to meet the basic needs of bandwidth services.

In one embodiment, the connection method between CPE 112 and emergency OLT 111 is not limited. For example, the two may be connected through, but not limited to, a preset router, or the two may be directly connected, etc., but not limited to.

In one embodiment, the VPN tunnel may be pre-built based on, but not limited to, at least one of the following:

Virtual Extensible Local Area Network (VxLAN);

Generic Routing Encapsulation (GRE);

Virtual Private Lan Service (VPLS);

Layer 2 Tunneling Protocol (L2TP).

Among them, each pre-construction method is well known to those skilled in the art and can be used alone or in combination. This is not limited in this embodiment. Specific examples will be given later to illustrate the pre-construction of VPN channels in different ways, which will not be described in detail here.

In one embodiment, the number of emergency OLTs 111 can be set to multiple, that is, some emergency OLTs 111 can be selected as backup OLTs to ensure that the emergency OLTs 111 can stably re-hang the ONUs 120. However, it can be understood that the main-backup protection switching method in the related art has a 1:1 requirement for equipment, that is, one main OLT requires one backup OLT, and the emergency device 110 can be suitable for sharing by multiple target OLTs. After a faulty target OLT is restored, it can be switched back to protect other faulty target OLTs. It is a one-to-many relationship. In other words, one emergency device 110 can be used by different target OLTs with problems, that is, the corresponding target OLTs are replaced by the emergency OLTs 111. For example, based on the emergency device 110 provided in this embodiment, only 1 to 2 sets are needed to support the emergency operation of the OLT equipment in a county, which has a significant cost advantage. The basic principle is the same and will not be repeated here. It has been verified that in actual use, one emergency OLT 111 can cover and protect about 100 target OLTs.

A specific example of the business processing device of the present application is given below.

Example 1:

As shown in FIG. 2 , FIG. 2 is a schematic diagram of an application scenario of a business processing device provided by an embodiment of the present application.

Since the trunk optical fiber between the PON port of the original OLT and the optical splitter is interrupted, the ONU service under the PON port is interrupted. Therefore, the original OLT is replaced by an emergency device, and the BRAS is used as the network access device. A VPN channel is established between the emergency device and the BRAS through a wireless network. The wireless network here is provided by the CPE uplink connection base station, that is, the wireless network is used to protect the wired network, and the ONU under the PON port of the original OLT is migrated to the emergency OLT on the emergency device. The emergency OLT in the emergency device sends the ONU authentication information to the BRAS through the VPN channel. The BRAS passes the ONU authentication and assigns an IP address to the ONU to complete the ONU service recovery.

Among them, the establishment of the VPN channel can adopt one or more tunnel technologies such as VxLAN, GRE, VPLS, L2TP, etc.

It can be seen that the emergency equipment shown in FIG. 2 includes a CPE, an emergency OLT, a router and a battery (not shown), and the internal connection relationship is that the CPE is connected to the router, and the router is connected to the emergency OLT.

Example 2:

As shown in Figure 3, Figure 3 is a schematic diagram of an application scenario of a business processing device provided by another embodiment of the present application, which uses VxLAN technology to establish a VPN channel between BRAS and OLT (ie, emergency OLT, which will not be repeated below).

First, the emergency equipment uses CPE to connect to the wireless network. The wireless core network provides services for enterprise customers and assigns fixed IP addresses to BRAS and CPE. CPE adopts bridging mode and uses VxLAN technology to establish a VPN channel between OLT and BRAS to achieve wireless network traversal.

Then, the pre-configured PNP function is used on the OLT of the emergency device, or the blind cut function is used on the network management to implement ONU service cutover. Cutover refers to migrating the ONU service under one PON port to another PON port. The two PON ports can be on the same device or on different devices. This example refers to migrating to the PON port of another device.

It should be noted that the PNP function is suitable for situations where the data configuration is relatively standardized. For example, in this case, the data of the ONUs under the OLTs in various areas are basically the same. In this case, the ONU data can be pre-configured on the OLT of the emergency equipment in advance. After the ONU is inserted into the PON optical fiber of the OLT, the OLT of the emergency equipment will automatically detect the serial number of the unauthenticated ONU, and replace the pre-configured ONU serial number with the SN number of the newly connected ONU, thereby realizing the plug-and-play function.

The blind cutover function customized by the network management is used to implement ONU service cutover, which is suitable for use on OLTs with less standardized data configuration. Specifically, when the network management detects the unauthenticated ONU registration reported by the OLT, it searches for the corresponding serial number on the original OLT according to the predetermined cutover task, and automatically generates an ONU configuration command, which is sent to the OLT of the emergency device to complete the ONU registration. Blind cutover is automatic cutover, which is to configure the rules on the network management first, and then unplug the optical fiber on one PON port and plug it into another PON port, so that the ONU service will be automatically migrated to the other PON port.

BRAS assigns OLT devices to the new domain and sets ONU authentication-free, or unbinds the ONU account under the target OLT on BRAS during emergency access so that the ONU authentication passes. After the ONU authentication passes, BRAS assigns an IP address to the ONU to restore the ONU service.

It should be noted that the above functions of the emergency equipment and network access equipment shown in Figures 1 to 3 can be applied to different application scenarios and are not limited here.

Those skilled in the art will appreciate that the emergency equipment and network access equipment shown in FIGS. 1 to 3 can be applied to 5G and 6G communication network systems and subsequently evolved mobile communication network systems, and this embodiment does not specifically limit this.

Those skilled in the art will appreciate that the emergency equipment and network access equipment shown in FIGS. 1 to 3 do not constitute limitations on the embodiments of the present application, and may include more or fewer components than shown in the figures, or a combination of certain components, or a different arrangement of components.

Based on the above-mentioned embodiments of the service processing device, various embodiments of the service processing method of the present application are proposed below.

As shown in FIG4, FIG4 is a flow chart of a service processing method provided by an embodiment of the present application, and the service processing method can be applied to, but not limited to, the emergency OLT in the embodiment shown in FIG1, the emergency OLT in the embodiment shown in FIG2, or the emergency OLT in the embodiment shown in FIG3. The service processing method may include, but is not limited to, steps S110 and S120.

Step S110: When a service failure occurs in an ONU connected to the target OLT, the ONU is registered.

Step S120: connecting the network access device via the wireless network, so that service data is transmitted between the network access device and the ONU based on the emergency OLT.

In this step, when a service failure occurs in the ONU under the target OLT, compared with the manual rescue in the related art, By restoring services, the emergency OLT in the emergency equipment is used to re-hang the ONU, and the ONU is registered through the emergency OLT, and the network access device is connected through the wireless network, so that service data is transmitted between the network access device and the ONU based on the emergency OLT, thereby reducing the recovery time of the ONU device service failure, further improving the recovery efficiency of the ONU device service failure, thereby filling the technical gap in the relevant method.

In one embodiment, when a service failure occurs in an ONU, the specific application forms of controlling the emergency OLT to attach an ONU can be various, which are not limited here. For example, it can be but not limited to: when a service failure occurs in an ONU attached to a target OLT, controlling the emergency OLT to replace the target OLT and attaching the ONU again, etc.

It should be noted that since steps S110 and S120 in this embodiment and the relevant embodiments of the above-mentioned business processing equipment belong to the same inventive concept and are completely corresponding to each other, the only difference is that the objects of the method and the device are different. Therefore, other specific implementation methods and related implementation methods of steps S110 and S120 in this embodiment can refer to the relevant specific embodiments of the business processing equipment in the above-mentioned embodiments. To avoid redundancy, other specific implementation methods and related implementation methods of steps S110 and S120 in this embodiment will not be repeated here.

As shown in FIG. 5 , an embodiment of the present application further illustrates step S120 , which includes but is not limited to steps S1201 to S1202 .

Step S1201: Establish a VPN channel through the wireless network provided by the CPE.

Step S1202: Connect to the network access device through the VPN channel.

In this step, a VPN channel is established between the emergency OLT and the network access device through the wireless network. The VPN channel in this case ensures good communication between the emergency OLT and the network access device. That is to say, it can not only provide an emergency OLT for re-hanging the ONU, but also provide a VPN channel accordingly to facilitate further recovery of the ONU's services. By improving the VPN channel service, the actual available downstream bandwidth can be greatly improved to meet the basic needs of bandwidth services.

In one embodiment, step S1201 includes but is not limited to one of the following: establishing a VPN channel through a wireless network provided by the CPE based on the VxLAN;

Establish a VPN channel through the wireless network provided by CPE based on GRE;

Establish a VPN channel based on VPLS through the wireless network provided by CPE;

A VPN channel is established based on L2TP through the wireless network provided by the CPE.

As shown in FIG. 6 , an embodiment of the present application further illustrates step S110 , which includes but is not limited to steps S1101 to S1103 .

Step S1101: receiving registration information sent by the ONU.

Step S1102: Detect the serial number of the ONU according to the registration information.

Step S1103: Replace the pre-configured target serial number with the detected ONU serial number, and register the ONU according to the target serial number.

In this step, by pre-configuring the plug-and-play (PNP) function on the emergency OLT, the plug-and-play of the ONU on the emergency OLT is realized, the usability is improved and the requirement for the skills of the operator is greatly reduced, that is, the emergency OLT can be used for, but not limited to: detecting the serial number of the ONU according to the received registration authentication information, and replacing the detected serial number of the ONU with a pre-configured target serial number, and completing the ONU registration according to the target serial number, that is, by pre-configuring the corresponding target serial number, when the ONU is accessed, the serial number of the ONU can be replaced with the pre-configured target serial number according to the registration authentication information sent by the ONU, thereby realizing the plug-and-play function. This configuration method is more suitable for emergency OLTs with data specifications.

It should be noted that since steps S1101 to S1103 in this embodiment are related to the implementation of the above-mentioned business processing device The examples belong to the same inventive concept and are completely corresponding to each other. The only difference is that the objects of the method and the device are different. Therefore, other specific implementation methods and related implementation methods of steps S1101 to S1103 in this embodiment can refer to the relevant specific implementation methods of the business processing device in the above embodiment. To avoid redundancy, other specific implementation methods and related implementation methods of steps S1101 to S1103 in this embodiment will not be repeated here.

As shown in FIG. 7 , in one embodiment of the present application, step S110 is further described. Step S110 includes but is not limited to steps S1104 to S1106 .

Step S1104: Receive registration information sent by the ONU.

Step S1105: The serial number of the ONU is obtained from the network management according to the registration information.

Step S1106: When receiving the configuration instruction from the network management, register the ONU according to the configuration instruction and the serial number of the ONU.

In this step, the serial number of the ONU and the data configuration corresponding to the serial number are searched from the network management according to the received registration authentication information, and when a configuration instruction is received from the network management, the ONU registration is completed according to the configuration instruction and the serial number of the ONU. That is to say, by searching the serial number of the ONU and the data configuration corresponding to the serial number from the network management, the corresponding serial number and the corresponding data configuration are configured for the ONU according to the configuration instruction of the network management, so that the access control of the ONU can be stably realized.

It should be noted that since steps S1104 to S1106 in this embodiment and the relevant embodiments of the above-mentioned business processing device belong to the same inventive concept and are completely corresponding to each other, the only difference is that the objects of the method and the device are different. Therefore, other specific implementation methods and related implementation methods of steps S1104 to S1106 in this embodiment can refer to the relevant specific embodiments of the business processing device in the above-mentioned embodiments. To avoid redundancy, other specific implementation methods and related implementation methods of steps S1104 to S1106 in this embodiment will not be repeated here.

In one embodiment of the present application, the steps before step S110 are further described, and the steps before step S110 also include but are not limited to step S130.

Step S130: Migrate the ONU from the target OLT to the emergency OLT.

In this step, the ONU is migrated from the target OLT to the emergency OLT so that the ONU migrated from the target OLT to the emergency OLT can be re-attached, and then the re-attached ONU can be registered.

It should be noted that since step S130 in this embodiment and the relevant embodiments of the above-mentioned business processing device belong to the same inventive concept and are completely corresponding to each other, the only difference is that the objects of the method and the device are different. Therefore, other specific implementation methods and related implementation methods of step S130 in this embodiment can refer to the relevant specific embodiments of the business processing device in the above-mentioned embodiments. To avoid redundancy, other specific implementation methods and related implementation methods of step S130 in this embodiment will not be repeated here.

Some specific examples of the business processing method of this application are given below.

Example 3:

As shown in FIG. 8 , FIG. 8 is a schematic diagram of an application scenario of a service processing device provided in another embodiment of the present application, in which a VPN channel is established between a BRAS and an OLT using VPLS and GRE technologies.

First, the emergency equipment uses CPE to connect to the wireless network for uplink. The wireless core network provides ordinary SIM cards with unlimited traffic and unlimited speed. Two sets of routers are deployed between the OLT and BRAS, and then the L2VPN channel of VPLS over GRE over L2TP is used to traverse the wireless network.

Then, the pre-configured PNP function is used on the OLT of the emergency equipment or the blind cut function is used on the network management to realize ONU service cutover. Cutover means migrating the ONU service under one PON port to another PON port. These two PON ports can It can be on the same device or on different devices. This example refers to migrating to the PON port of another device.

It should be noted that for the PNP function, the ONU data can be pre-configured on the OLT of the emergency equipment in advance. The OLT of the emergency equipment will automatically detect the serial number of the unauthenticated ONU, and automatically replace the pre-configured ONU serial number with the SN number of the earliest offline ONU to realize ONU registration.

Use the network management customized blind cutover function to implement ONU service cutover. Specifically, when the network management detects the unauthenticated ONU registration reported by the OLT, it searches for the corresponding serial number on the original OLT according to the predetermined cutover task, and automatically generates an ONU configuration command, which is sent to the OLT of the emergency device to complete the ONU registration.

BRAS assigns OLT devices to the new domain and sets ONU authentication-free, or unbinds the ONU account under the target OLT on BRAS during emergency access to enable ONU authentication. After ONU authentication is passed, BRAS assigns an IP address to the ONU to restore ONU services.

Example 4:

As shown in Figure 9, Figure 9 is a schematic diagram of an application scenario of a business processing device provided by another embodiment of the present application, which adopts VPLS over GRE over IPSec (Internet Protocol Security) technology to establish a VPN channel between BRAS and OLT.

First, a router is deployed on the OLT side, and an L2VPN channel of VPLS over GRE over IPSec is used between the OLT and the router on the BRAS side to traverse the wireless network.

It should be noted that since the business processing device in this embodiment and the related embodiments of the above-mentioned business processing devices and methods belong to the same inventive concept, other specific implementation modes and related implementation modes of the business processing device in this embodiment can refer to the related specific embodiments of the business processing devices and methods in the above-mentioned embodiments.
