Detailed Description

In order to make the objects, technical methods and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

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

The application provides a service processing method and device, an OLT device and a computer readable storage medium. The service processing method of one embodiment is applied to the emergency OLT, and comprises the following steps: registering the ONU under the condition that the ONU hung under the target OLT has service faults; and connecting the network access equipment through a wireless network so as to enable the service data transmission between the network access equipment and the ONU based on the emergency OLT. In this embodiment, in the case that a service fault occurs in an ONU suspended under a target OLT, compared with a manual preemption recovery service in the related art, an emergency OLT is adopted to suspend and register the ONU again, and a network access device is connected through a wireless network, so that service data transmission is performed between the network access device and the ONU based on the emergency OLT, thereby reducing the recovery time of the service fault of the ONU device, further improving the recovery efficiency of the service fault of the ONU device, and making up for the technical blank in the related method.

Embodiments of the present application are further described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is a schematic diagram of a service processing apparatus provided in an embodiment of the present application, where the service processing apparatus includes, but is not limited to, an emergency OLT111 and customer premises equipment (Customer Premises Equipment, CPE) 112, and the CPE112 is connected to the emergency OLT 111.

In the case that the ONU120 has a service failure, for example, a backbone fiber of a target OLT corresponding to the ONU120 is broken, the emergency OLT111 is configured to register the ONU120 suspended under the target OLT, that is, the ONU120 is completed to register according to the received registration information, and the registration information is sent to the emergency OLT111 by the ONU120 under the condition of being suspended under the emergency OLT111, where "suspended under" is used to characterize a functional correspondence, that is, the ONU120 is suspended under the emergency OLT111, which indicates that the ONU120 can implement a specific function only by the emergency OLT 111.

The CPE112 is configured to provide a wireless network for the emergency OLT111, so that the emergency OLT111 is connected to the network access device 130 through the wireless network, and further, service data transmission is performed between the network access device 130 and the ONU120 based on the emergency OLT111, so that a recovery time of a service failure of the ONU120 can be reduced, and recovery efficiency of the service failure of the ONU120 is further improved, where the wireless network is used for constructing a VPN channel, and the VPN channel is used by the emergency OLT111 to implement service recovery of the registered ONU120, and it is required that the service recovery refers to that various services of the ONU can normally operate, including, but not limited to, services such as surfing the internet;

the network access device 130 is configured to perform service data transmission with the ONU120 based on the emergency OLT111, that is, may, but not limited to, receive authentication information of the ONU120 sent by the emergency OLT111 through a VPN channel, authenticate by the ONU120 according to the authentication information of the ONU120, and allocate an IP address to the authenticated ONU120 to implement service recovery of the authenticated ONU120, that is, may improve interaction quality between the network access device 130 and the emergency OLT111 through the VPN channel, and greatly improve an actual downlink available bandwidth, so as to be capable of meeting a requirement of the network access device 130 for service recovery of the ONU 120.

In the case that the ONU120 has a service failure, compared with the manual preemption recovery service in the related art, the emergency OLT111 in the emergency device is adopted to hang the ONU120 again, the ONU120 is registered through the emergency OLT111, and a wireless network for constructing a VPN channel is provided for the emergency OLT111 through the CPE112, so that the service recovery of the ONU120 is realized through the cooperation of the VPN channel and the emergency OLT111, the recovery time of the service failure of the ONU120 device can be reduced, the recovery efficiency of the service failure of the ONU120 device is further improved, and the technical blank in the related method can be made up; through verification, the recovery time of the ONU120 service can be shortened from 2 to 3 hours to about 15 minutes, so that the efficiency of the ONU120 service recovery can be greatly improved.

It should be noted that, there may be various situations when the ONU120 fails in service, for example, when the ONU120 suspended from the target OLT fails in service, at this time, the emergency OLT111 replaces the target OLT to suspend the ONU120 again, which is not limited herein, and requires specific analysis in specific situations. For example, it is common that a backbone fiber connected to a PON fiber interface of a target OLT in a PON breaks, that is, the backbone fiber connected to a corresponding optical splitter of the target OLT breaks, and the optical splitter is further connected to the ONU120, so that the service of the ONU120 is broken to form a service fault; as another example, the ONU120 cannot be matched with the target OLT, so that the ONU120 cannot be managed well, and thus, the ONU120 has a service failure, i.e. the ONU120 may have a problem of causing the service failure.

In an embodiment, the types, parameters and the like of the emergency OLT111 and the target OLT are not limited, and the emergency OLT111 is equivalent to a standby OLT serving as the target OLT, so that the target OLT can configure the ONU120 by adopting the emergency OLT111 when a problem occurs, and thus the problem that the ONU120 has a service fault in the case can be solved; moreover, ONU devices of different manufacturers can be supported for application, and specific application scenarios are not limited herein.

In an embodiment, the specific form and content of the registration information and the authentication information sent by the ONU120 are not limited, for example, the authentication message may be, but not limited to, an authentication message such as a user broadband account user name, a password, etc., and may be set according to a specific application scenario, which is not described herein.

In an embodiment, the specific manner in which the emergency OLT111 completes the registration of the ONU120 according to the received registration information is not limited, and a person skilled in the art may set the method according to the actual application scenario. For example, by pre-configuring a Plug-and-Play (PNP) function on the emergency OLT111, the ONU120 can implement Plug-and-Play on the emergency OLT111, which improves usability while greatly reducing the requirements for the skill of the operator, i.e. the emergency OLT111 can be used, but is not limited to, specifically: detecting the serial number of the ONU120 according to the received registration information, replacing the preconfigured target serial number with the detected serial number of the ONU120, and completing the ONU120 registration according to the target serial number, namely, by preconfiguring the corresponding target serial number, the preconfigured target serial number can be replaced with the serial number of the ONU120 according to the registration information sent by the ONU120 when the ONU120 is accessed, so that the plug-and-play function is realized, and the configuration mode is more suitable for the emergency OLT111 with the data specification; as another example, the ONU120 service cutover may also be implemented by means of a network management, and the function is more suitable for the emergency OLT111 with less data standard, i.e. the emergency OLT111 may be, but is not limited to, specifically used for: the serial number of the ONU120 and the data configuration corresponding to the serial number are obtained by searching from a preset or predetermined network manager according to the received registration information, and the ONU120 registration is completed according to the configuration instruction and the serial number of the ONU120 under the condition that the configuration instruction from the network manager is received, that is, the corresponding serial number of the ONU120 and the data configuration corresponding to the serial number are searched from the network manager, so that the corresponding serial number and the corresponding data configuration are configured for the ONU120 according to the configuration instruction of the network manager.

In an embodiment, the specific type of the network access device 130 is not limited, and may be selected according to the actual scenario. For example, to merge 5G and fixed network broadband traffic, the network access device 130 may be configured as a broadband access server (Broadband Remote Access Server, BRAS); as another example, in a wireless network access scenario, network access device 130 may be, but is not limited to being, configured as a corresponding network device or the like.

In an embodiment, the CPE112 may be connected to an external wireless network so as to establish a VPN channel between the emergency OLT111 and the network access device 130 through the wireless network, and the VPN channel in this case ensures a good communication effect between the emergency OLT111 and the network access device 130, that is, not only can the emergency OLT111 re-hang the ONU120 be provided, but also the VPN channel can be provided correspondingly so as to further implement service recovery of the ONU120, and by improving the VPN channel service, the actual downlink available bandwidth can be greatly improved, and the basic requirement of the bandwidth service is met.

In an embodiment, the connection manner between the CPE112 and the emergency OLT111 is not limited, for example, the connection between the CPE and the emergency OLT may be, but not limited to, a preset router, or the connection between the CPE and the emergency OLT may be, but not limited to, a direct connection.

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

virtual extended local area network (Virtual Extensible Local Area Network, vxLAN);

generic routing encapsulation (Generic Routing Encapsulation, GRE);

virtual private local area network traffic (Virtual Private Lan Service, VPLS);

layer two tunneling protocol (Layer 2Tunneling Protocol,L2TP).

The pre-construction modes are well known to those skilled in the art, and may be used alone or in combination, and are not limited in this embodiment, and specific examples will be given later to illustrate pre-construction VPN channels in different modes, which are not described herein.

In an embodiment, the number of emergency OLTs 111 may be set to be multiple, i.e. some emergency OLTs 111 may be selected as standby OLTs to ensure that the emergency OLTs 111 can stably re-mount the ONUs 120, but it is understood that the requirements of the active-standby protection switching mode in the related art on the device are 1:1, namely, one main OLT needs one standby OLT, while the emergency device 110 can be suitable for sharing by a plurality of target OLTs, and after a failed target OLT fails to recover, the emergency device 110 can protect other failed target OLTs in a one-to-many relationship, that is, one emergency device 110 can be used by different failed target OLTs, that is, the emergency device 111 is used to replace the corresponding target OLTs respectively, for example, only 1 to 2 sets of emergency devices 110 provided by the embodiment are needed to be used for supporting the OLT devices of a county to rob, so that the emergency device has obvious cost advantages, the basic principle is consistent, and the emergency device is not repeated herein; through verification, in the actual use process, one emergency OLT111 can perform coverage protection on about 100 target OLTs.

A specific example of the service processing apparatus of the present application is given below.

Example one:

fig. 2 is a schematic application scenario diagram of a service processing device according to an embodiment of the present application, as shown in fig. 2.

Because the main optical fiber between the PON port of the original OLT and the optical splitter is interrupted, the ONU business suspended below the PON port is interrupted, so that the emergency equipment is used for replacing the original OLT, a BRAS is used as network access equipment, a VPN channel is established between the emergency equipment and the BRAS through a wireless network, the wireless network is provided by a CPE uplink connection base station, namely, the wireless network is utilized to protect a wired network, the ONU suspended below the PON port of the original OLT is migrated to the emergency OLT on the emergency equipment, the emergency OLT in the emergency equipment transmits the authentication information of the ONU to the BRAS through the VPN channel, and the BRAS authenticates the ONU and distributes an IP address to the ONU to complete the ONU business recovery.

The VPN tunnel may be established by one or more tunneling techniques such as VxLAN, GRE, VPLS, L TP.

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

Example two:

fig. 3 is a schematic application scenario diagram of a service processing device according to another embodiment of the present application, where a VxLAN technology is used to establish a VPN channel between a BRAS and an OLT (i.e., an emergency OLT, which will not be described in detail below).

Firstly, the emergency equipment is connected with a wireless network by adopting CPE (customer premise equipment), the wireless core network provides business oriented to enterprise customers, fixed IP addresses are distributed to BRAS and CPE, the CPE adopts a bridging mode, a VPN (virtual private network) channel is established between the OLT and the BRAS by adopting a VxLAN (virtual private LAN) technology, and the wireless network is traversed.

Then, a preconfigured PNP function is adopted on the OLT of the emergency device or a blind cut function is adopted on the network manager, so that ONU service cut-over is realized, the cut-over refers to that ONU service under one PON port is migrated under another PON port, the two PON ports can be on the same device or on different devices, and the example refers to migration under the PON port of another device.

It should be noted that, the PNP function is suitable for the case of the data configuration comparison standard, for example, in this case, the data of the ONUs hung under the OLT of each area are basically the same, so that the data of the ONUs can be pre-configured on the OLT of the emergency device, after the ONUs are inserted into the PON port optical fiber of the OLT, the OLT of the emergency device can automatically detect the serial numbers of the unauthorized ONUs, and replace the serial numbers of the pre-configured ONUs with the SN numbers of the newly accessed ONUs, thereby realizing the plug-and-play function.

The network management customized blind cut function is used for realizing ONU service cut-over, and is suitable for being used on an OLT with less data configuration standards, specifically, when the network management detects the registration of an unauthorized ONU reported by the OLT, the network management searches a corresponding serial number on the original OLT according to a preset cut-over task, automatically generates an ONU configuration command, and issues the ONU configuration command to the OLT of emergency equipment to complete ONU registration, wherein blind cut-over is automatic cut-over, specifically, rules are configured on the network management firstly, then an optical fiber on one PON port is pulled out and inserted into the other PON port, and then the ONU service is automatically migrated to the other PON port.

The BRAS designates the OLT equipment into a new domain, and sets ONU authentication-free, or when emergency robbing is conducted, unbinding operation is conducted on the ONU account under the target OLT on the BRAS, so that the ONU authentication is passed. And when the ONU passes authentication, the BRAS distributes an IP address for the ONU to realize the service recovery of the ONU.

It should be noted that the functions of the emergency device and the network access device shown in fig. 1 to 3 may be applied to different application scenarios, which is not limited herein.

It will be appreciated by those skilled in the art that the emergency device and the network access device shown in fig. 1 to 3 may be applied to a 5G and 6G communication network system, a mobile communication network system that is evolved later, and the like, which is not particularly limited in this embodiment.

It will be appreciated by those skilled in the art that the emergency device, network access device illustrated in fig. 1-3 are not limiting to the embodiments of the present application, and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.

step S120: and connecting the network access equipment through a wireless network so as to enable the service data transmission between the network access equipment and the ONU based on the emergency OLT.

In this step, in the case that the ONU suspended under the target OLT has a service failure, compared with the manual preemption recovery service in the related art, the emergency OLT in the emergency device is adopted to suspend the ONU again, and registers the ONU through the emergency OLT, and connects the network access device through the wireless network, so that the service data transmission is performed between the network access device and the ONU based on the emergency OLT, thereby reducing the recovery time of the service failure of the ONU device, further improving the recovery efficiency of the service failure of the ONU device, and making up the technical blank in the related method.

In an embodiment, in the case that the ONU has a service failure, the specific application form of controlling the ONU to be suspended under the emergency OLT may be various, which is not limited herein. For example, but not limited to: and under the condition that the ONU hung down on the target OLT has service faults, the emergency OLT is controlled to replace the target OLT to hang down the ONU again, and the like.

It should be noted that, since the steps S110 and S120 in this embodiment belong to the same inventive concept as the related embodiments of the service processing apparatus described above, they are completely corresponding to each other, and the difference is only that the method and the apparatus are different, so that other specific implementations of the steps S110 and S120 and related implementations of the method and apparatus in this embodiment may refer to the related specific embodiments of the service processing apparatus in the foregoing embodiment, and in order to avoid redundancy, other specific implementations of the steps S110 and S120 and related implementations of the embodiment are not described herein.
