Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The embodiment of the invention relates to a fault positioning method, which is a schematic view of a use scene of the method as shown in fig. 1. In network structure design, a network structure may be divided into an access layer, a convergence layer, and a core layer. The access layer is used for providing the capability of connecting or accessing the network for the user, and the base station can be connected into the network. Access layer transport devices typically have low cost and high port density characteristics and are typically connected in series to form an access ring. The convergence layer is a part positioned between the access layer and the core layer and provides data convergence \ transmission \ management \ distribution processing for the access layer. The convergence layer transmission equipment is a convergence point of a plurality of access layer transmission equipment, can process all communication requirements from the access layer transmission equipment, converges and forwards data to core layer equipment, and is connected in series to form a convergence ring. The core layer is a network backbone part and is used for guaranteeing the performance of the whole network, and the core layer mainly aims to provide a fast and reliable backbone transmission structure through high-speed forwarding communication. Therefore, the core layer transmission equipment should have higher reliability, performance and throughput. Meanwhile, for some areas with relatively large traffic volume or areas with relatively complex traffic, a network operator usually sets an L2/L3 layer for data processing, the L2/L3 layer is usually set between the convergence layer and the core layer, and the L2/L3 layer transmission device integrates an L2VPN and an L3VPN for bridging the L2VPN applied to the convergence layer and the L3VPN applied to the core layer.

In order to realize the management of the network and realize the rapid positioning when the network fails, the system provides a network management system, such as: when a large-scale base station returns to service in a certain area, the network management system needs to quickly locate the fault reason, and fault troubleshooting is carried out on the returning base station, the access layer equipment, the convergence layer equipment, the L2/L3 layer equipment and the core layer equipment so as to locate the fault reason. As shown in fig. 2, in order to reduce the time for finding a fault, a fault location system applied in the embodiment of the present invention generally includes: the system comprises a comprehensive resource module, a topology generation module, an alarm module, a fault root cause analysis module and the like, wherein the comprehensive resource module is used for managing equipment information in a network architecture and storing static resource information including a network topology structure, the equipment information, a relevant data table and the like, for example: the service circuit table is used for storing the relation between the base station and the uplink transmission layer equipment; a transmission topology relation table for storing the connection relation between the access layer transmission device and the convergence layer transmission device; an access ring resource table for storing the relationship between the access ring and the intra-ring transmission device; a convergence ring resource table for storing the relationship between the convergence ring and the in-ring transmission device; and the circuit routing table is used for storing the information of each routing segment of the circuit, and comprises the relationship between the convergence layer transmission equipment and the L2/L3 layer equipment, the relationship between the L2/L3 layer equipment and the core layer equipment and the like. Meanwhile, the comprehensive resource module also connects the resources and the equipment in series according to the stored information. The topology generation module connects the base station, the access layer, the convergence layer, the L2\ L3 layer and the transmission equipment of the core layer in series through the resource relation in the comprehensive resource module to form the topology relation of the whole network, after fault polling is carried out on the equipment in the topology, fault alarm is sent out by the alarm module aiming at the equipment with faults, after the alarm information is summarized, the fault root cause analysis module carries out root cause analysis on all the alarms, and finally the alarm is presented to a network administrator for fault positioning. All the embodiments provided by the invention are applied to the network architecture and the network management system, the topological structure is dynamically generated according to each fault condition through a dynamic topological generation technology, and the fault location is only carried out on equipment related to equipment which cannot provide service, so that the fault location efficiency is greatly improved.

Fig. 3 shows a flow chart of an embodiment of a fault location method of the present invention, which includes the following steps:

step S110: and determining an access ring where the access layer transmission equipment connected with the equipment which cannot provide the service is located.

In this step, the device that cannot provide service is usually a base station that fails to provide service due to a major failure, and the base station accesses the network through an access stratum transmission device, and a plurality of access stratum transmission devices form an access ring. One access stratum transmission device is usually connected with a plurality of base stations, and in case of a serious accident, the number of the base stations which can not provide service is also usually a plurality. For example, when the number of the base stations which cannot provide service is 100, 60 base stations may be all connected to one access stratum transmission device, and the remaining 40 base stations may be all connected to another access stratum transmission device. The two access stratum transmission devices may be located in different access rings, and thus the number of access rings determined in this step may be multiple.

And the access ring where each access layer transmission device is located can be stored in the static resource of the comprehensive resource module in advance, so that the access ring where the access layer transmission device connected with the base station is located can be determined through the static resource. As shown in fig. 4, the service circuit table 101 stores a transmission device ID, a transmission device name, a base station ID, and a base station name, and the access ring resource table 102 stores an access ring ID, an access network name, a transmission device ID, and a transmission device name. According to the preset service circuit table 101 and the access ring resource table 102, the access ring ID where the access layer transmission device connected to the device that cannot provide service is located can be determined.

As shown in fig. 4, the service circuit table 101 and the service circuit table 102 are stored in advance in the integrated resource module. When a major accident occurs, the service circuit table 101 may use the ID information of the base station that cannot provide service to find the ID information of the access layer transmission device connected to the base station, and then use the ID information of the access layer transmission device to find the ID information of the access ring where the base station is located through the service circuit table 102. For example, when the number of the base stations which cannot provide service is 100, wherein the base stations with the base station IDs of a1-a60 are all connected with the access stratum transmission equipment with the ID of b1, and the access ring ID of the access stratum transmission equipment with the ID of b1 is c1, the access ring c1 can be determined. In addition, the base station with the ID of a61-a100 is connected with the access stratum transmission equipment with the ID of b2, and the access ring with the ID of b2 is located in the access ring with the ID of c2, so that another access ring is determined.

Step S120: and all the access layer transmission equipment in the access ring are connected in series and are connected in series with the equipment which can not provide the service.

In this step, all access stratum transmission devices within the access ring may be determined by the static resources in the integrated resource module. The series connection of the transmission devices can be completed through the original topological relation, and the original topological relation can be inquired through the transmission topological relation table 103 and then is connected in series with the base station which can not provide service, so as to form a new access ring topology. Wherein, the serial connection with the base station which can not provide service is realized by the serial connection of the access layer transmission equipment in the finger access ring and the base station which can not provide service and is connected with the access layer transmission equipment. The access stratum transmission equipment may also connect some normal base stations, but in the new access ring topology, these normal base stations are not connected in series.

Specifically, after determining the ID information of the access ring, the service circuit table 102 may look up the IDs of all access stratum transmission devices under this access ring ID. For example, if the access ring ID determined in step S110 is c1, and the IDs of the access stratum transport devices belonging to c1 are b1, b3, and b4 in the access ring resource table 102. Then the access stratum transmission devices with ID numbers b1, b3 and b4 are all the access stratum transmission devices in the access ring with ID number c1, and the access stratum transmission devices with ID numbers b1, b3 and b4 are connected in series.

It should be noted that: the specific connection relationship of these access stratum transmission devices needs to be determined by the transmission topology relationship table 103. The transmission topology relation table 103 includes: the system comprises a home terminal transmission device ID, a home terminal hierarchy, an opposite terminal transmission device ID and an opposite terminal hierarchy. When two transmission devices are in the local end-to-end relationship, the connection between the two transmission devices is represented. For example, when the transmission topology relation table 103 includes an access stratum at the home level and an opposite level, a home transport device ID b1 and an opposite transport device ID b3, it indicates that two devices with access stratum transport device IDs b1 and b3 are connected in series. Therefore, it can be determined by the transmission topology relation table 103 how the access stratum transmission devices in the access ring are connected two by two.

Further, devices that cannot provide services may also be statically resource-determined in the integrated resource module. As shown in fig. 4, the active alarm pool 11 includes a major accident alarm ID, a fallback alarm ID, a base station name, and a base station ID. When major faults occur, the system can generate a major accident alarm ID, the major accident alarm ID corresponds to a quit alarm ID, and the same quit alarm ID corresponds to a plurality of base station IDs. Therefore, all the withdrawn base station IDs, namely the equipment which can not provide service, can be found through the withdrawn alarm ID. And these fallback base station IDs may correspond to multiple access stratum transport device IDs. For example, the serving base station ID is a1-a100, where a1-a60 corresponds to an access stratum transmission device with ID b1, a61-a100 corresponds to an access stratum transmission device with ID b2, b1 belongs to the access ring c1, and b2 belongs to the access ring c2, then the access stratum transmission device with ID b1 is connected in series with the base station with ID a1-a60, and other access stratum transmission devices in the access ring c1, such as b3 and b4, which are not connected with the serving base station, do not need to connect in series with the base station. Similarly, an access stratum transmission device with an ID of b2 is connected in series with a base station with an ID of a61-a 100.

Step S130: polling all the access layer transmission devices and determining the convergence layer transmission device connected with the access layer transmission device.

In this step, the all access stratum transmission devices are all the access stratum transmission devices in the access ring determined in step S120. Polling refers to sequentially searching whether each access layer transmission device in the access ring has a connected convergence layer transmission device in the original topological relation. And if the access layer transmission equipment is in the local end-to-end relationship with the convergence layer transmission equipment in the topological relationship, marking. The local end relationship refers to correspondence between a local end hierarchy and an opposite end hierarchy in the transmission topology relationship table 103. After all the transmission devices are polled, the marked convergence layer transmission devices are extracted. And the searched convergence layer transmission equipment is the convergence layer transmission equipment determined in the step.

Specifically, as shown in fig. 4, a transmission topology relation table 103 is stored in the integrated resource module, and includes: the system comprises a home terminal transmission device ID, a home terminal hierarchy, an opposite terminal transmission device ID and an opposite terminal hierarchy. The transmission topology relation table 103 stores the connection relation between the access layer and convergence layer transmission devices. When the found access layer transmission device ID is the same as the home terminal transmission device ID in the transmission topology relation table 103, and the home terminal hierarchy and the peer terminal hierarchy of the transmission topology relation table 103 are the access layer and the convergence layer, respectively, the peer terminal transmission device ID in the transmission topology relation table 103 is the convergence layer transmission device ID to be determined. For example, when the home terminal transmission device ID, the home terminal hierarchy, the peer terminal transmission device ID, and the peer terminal hierarchy of the transmission topology relation table 103 are b1, an access layer, e1, and a convergence layer, respectively, an access layer transmission device with ID number b1 and a convergence layer transmission device with ID number e1 have a connection in the original topology relation, and the convergence layer transmission device with ID number e1 is the convergence layer transmission device that needs to be determined in this step.

Step S140: and determining a convergence ring where the convergence layer transmission equipment is located according to the convergence layer transmission equipment.

As shown in fig. 4, the aggregation ring resource table 104 in the integrated resource module includes an aggregation ring ID, an aggregation ring name, an aggregation layer transmission device ID, and an aggregation ring transmission device name, and according to the aggregation ring resource table 104, an aggregation ring where an aggregation layer transmission device having a connection relationship with an access layer transmission device is located can be determined. For example, if the aggregation layer transport device ID determined in the above step to have a connection relationship with the access stratum transport device is e1, and the aggregation ring ID to which the aggregation layer transport device e1 belongs in the aggregation ring resource table 104 is f1, the aggregation ring with ID f1 is the aggregation ring that needs to be determined in this step.

Step S150: and all the convergence layer transmission equipment in the convergence ring are connected in series and are connected in series with the access layer transmission equipment.

In this step, the convergence layer transmission device included in the convergence layer is also pre-stored in the static resource of the integrated resource module. The series connection of the transmission devices can be completed through the original topological relation, and then the transmission devices are connected with the access layer transmission devices in series to form a new convergence ring topology. Specifically, the concatenation with the access stratum transmission device refers to that the convergence layer transmission device determined in step S130 is respectively concatenated with the access stratum transmission device having a connection relationship in the original topology relationship.

Specifically, as shown in fig. 4, after determining the aggregation ring ID, the aggregation ring resource table 104 may be used to find IDs of aggregation layer transmission devices belonging to the same aggregation ring ID, where all the aggregation layer transmission devices of these IDs are all aggregation layer transmission devices in the aggregation ring. For example, the convergence layer transmission devices under the convergence ring with ID f1 are e1, e2 and e3, and the convergence layer transmission devices with ID e1, e2 and e3 are all the convergence layer transmission devices in the convergence ring with ID f1, and the convergence layer transmission devices with ID e1, e2 and e3 are connected in series.

It should be noted that: the specific connection relationship of these convergence layer transmission devices needs to be determined by the transmission topology relationship table 103. For example, when the transmission topology relation table 103 has a home-level and an opposite-level both being aggregation levels, a home-level transmission device ID being e1, and an opposite-level transmission device ID being e2, it indicates that two devices with aggregation-level transmission device IDs being e1 and e2 are connected in series. Thus, it can be determined by the transmission topology relationship table 103 how the convergence layer transmission devices in the convergence ring are connected two by two.

Further, the access stratum transmission devices that need to be connected in series can also be determined by the transmission topology relation table 103. For example, the access ring is determined to be c1 in the above step, the access ring c1 includes an access stratum transmission device b1, and the determined convergence layer transmission devices are e1, e2 and e 3. In the transmission topology relationship table 103, the home terminal hierarchy and the opposite terminal hierarchy are an access layer and a convergence layer, respectively, the home terminal transmission device ID is b1, and the opposite terminal transmission device ID is e1, which indicates that the convergence layer transmission device e1 and the access layer transmission device b1 are connected in series, and the access layer transmission device b1 and the convergence layer transmission devices e1, e2, and e3 are connected in series.

Step S160: polling all convergence layer transmission devices and determining core layer transmission devices connected with the convergence layer transmission devices.

Step S170: and connecting the core layer transmission equipment and the convergence layer transmission equipment in series.

In step S160, the all convergence layer transmission devices are all convergence layer transmission devices within the convergence ring determined in step S150. In this step, it is also sequentially searched whether each convergence layer transmission device in the convergence ring has a connected core layer transmission device in the original topology relationship. And then, the convergence layer transmission equipment and the core layer transmission equipment which have connection relation in the original topological relation are connected in series, so that the whole series connection and presentation of the dynamic topology can be realized. The dynamic topology is connected in series with the deputy base station and all transmission devices in an access ring, transmission devices in a convergence ring and core layer transmission devices associated with the deputy base station.

Compared with the original network topology formed by static resources, the dynamic topology formed by the embodiment of the invention has simpler structure and does not comprise equipment irrelevant to faults, thereby reducing the time for locating the faults. In addition, the dynamic topology can also change in real time along with different out-of-service base stations, a new network topology can be formed according to different fault conditions, and the method is very convenient.

Step S180: and respectively carrying out fault location on the core layer transmission equipment, the convergence layer transmission equipment, the access layer transmission equipment and the equipment which cannot provide the service which are connected in series.

After the dynamic topology is generated, fault location needs to be performed in the dynamic topology. Since the base station may be out of service on its own or its associated transmission equipment, the access layer transmission equipment, the convergence layer transmission equipment and the core layer transmission equipment connected to the out-of-service base station also need to perform fault location.

The embodiment of the invention eliminates the equipment irrelevant to the fault in the original network topology by forming a new dynamic topology, so that the structure of the network topology is simpler, and the fault positioning of the core layer transmission equipment, the convergence layer transmission equipment, the access layer transmission equipment and the quit service base station in the dynamic topology is simpler and more convenient.

Fig. 5 is a flow chart illustrating sub-steps of concatenating all access stratum transport devices within the access ring with the non-service capable device according to another embodiment of the present invention. When a large number of base stations which cannot provide service are connected to a plurality of different access layer transmission devices, the system needs to count and classify fault conditions, and performs classification processing according to the conditions of the access rings of the base stations which cannot provide service, specifically:

step S121: and determining the number of devices which cannot provide services and are connected with the access layer transmission devices in each access ring.

As described above, the access ring determined in step S110 may be multiple, and the number of the base stations which cannot provide service and to which the access stratum transmission device is connected in these access rings may be different. For example, the number of non-serving base stations to which they are connected, i.e., the number of unsubscribed base stations, may be 60, 40, 20, 2, and 1, respectively, and so on. And the access ring with the larger number of the base stations which are out of service is more likely to be the fault.

Step S122: and determining an access ring according to the number.

Since the access ring with the particularly small number of connected resignant base stations is unlikely to be the place where the failure occurs, in order to reduce the complexity of the newly generated access ring topology, only the access ring with the large number of connected resignant base stations, for example, the access ring with the first three connected resignant base stations, may be selected.

Step S123: and respectively connecting all the access layer transmission equipment in the determined access rings in series, and respectively connecting the determined access layer transmission equipment with the equipment which can not provide the service in series.

In this step, the plurality of access rings determined in step S122 may form a plurality of new access ring topologies, and these access ring topologies may be further connected in series with the transmission device of the convergence layer and the core layer to form a dynamic topology.

The embodiment of the invention only selects the access rings with more connected and unsuccessfully-served base stations, thereby avoiding excessive access rings and increasing the complexity of the finally generated dynamic topology.

In some embodiments, the network structure is additionally provided with an L2/L3 layer, and correspondingly, the dynamic topology structure is also provided with an L2/L3 layer transmission device. Fig. 6 shows a flow chart of another embodiment of the present invention. As shown in fig. 6, specifically:

step S161: polling all convergence layer transmission devices to determine L2/L3 layer transmission devices having a connection with the convergence layer transmission device.

Step S162: and the L2/L3 layer transmission equipment is connected with the convergence layer transmission equipment in series.

Step S163: determining a core layer transmission device connected with the L2/L3 layer transmission device.

Step S164: and connecting the core layer transmission equipment with the L2/L3 layer transmission equipment in series.

In an alternative manner, the L2/L3 layer transmission devices having connections with the convergence layer transmission device and the core layer transmission devices having connections with the L2/L3 layer transmission devices may be determined according to a preset circuit routing table 105.

As shown in fig. 4, the circuit routing table 105 stores the information of each routing segment of the circuit, which includes the relationship between the convergence layer transmission device and the L2/L3 layer transmission device and the L2/L3 layer transmission device and the core layer transmission device, including the a-side layer, the Z-side layer, the a-side transmission device ID and the Z-side transmission device ID. After all the convergence layer transmission devices in the convergence ring are determined, L2/L3 layer transmission devices connected with the convergence layer transmission devices are sequentially searched in the circuit routing table 105, and then core layer transmission devices connected with L2/L3 layer transmission devices are sequentially searched in the circuit routing table 105. For example, the convergence ring determined by the above steps is f1, and all convergence layer transmission devices in the convergence ring f1 are e1, e2 and e 3. In a circuit routing table 105, the a-side layer, the Z-side layer, the a-side transmission device ID, and the Z-side transmission device ID are L2/L3 layer, aggregation layer, g1, and e1, respectively, when polling all aggregation layer transmission devices, the L2/L3 layer transmission device that needs to be determined is g1, and then the aggregation layer transmission devices e1 and L2/L3 layer transmission devices g1 are connected in series, while the aggregation layer transmission devices in the aggregation ring f1 are e2 and e3, and if no connected L2/L3 layer transmission device is found in the circuit routing table 105, the L2/L3 layer transmission devices do not need to be connected in series. Then, if another circuit routing table 105 is found, the a-side layer, the Z-side layer, the a-side transmission device ID, and the Z-side transmission device ID of the circuit routing table are respectively the core layer, the L2/L3 layer, the h1, and the g1, the core layer transmission device to be determined is h1, and then the L2/L3 layer transmission device g1 and the core layer transmission device h1 are connected in series.

It can be understood that: when there is no L2/L3 layer in the network structure, the core layer transmission devices having connections to the convergence layer transmission device can be directly searched in the circuit routing table 105 in turn.

Correspondingly, when the core layer transmission equipment is additionally provided with the L3 function, an L2/L3 layer is added between the convergence layer and the core layer in the original network structure, the L2/L3 layer is mainly used for bridging of the L2VPN and the L3VPN, and the L2/L3 layer transmission equipment is integrated with the L2VPN and the L3 VPN. Accordingly, in the original topological relationship, there are also topological relationships between convergence layer transmission devices and L2/L3 layer transmission devices and between L2/L3 layer transmission devices and core layer transmission devices. Therefore, in the newly formed dynamic topology, the convergence layer transmission device firstly connects L2/L3 layer transmission devices in series, and then connects the L2/L3 layer transmission devices in series with the core layer transmission devices connected with the convergence layer transmission devices.

In this embodiment of the present invention, the performing fault location on the core layer transmission device, the convergence layer transmission device, the access layer transmission device, and the device incapable of providing service, which are connected in series, specifically includes:

and respectively carrying out fault location on the core layer transmission equipment, the L2/L3 layer transmission equipment, the convergence layer transmission equipment, the access layer transmission equipment and the equipment which cannot provide services which are connected in series.

Due to the fact that L2/L3 layer transmission equipment is added to the dynamic topology, the step S180 needs to increase the fault location of the L2/L3 layer transmission equipment.

In a preferred embodiment of the present invention, the fault location is performed on the core layer transmission device, the L2/L3 layer transmission device, the convergence layer transmission device, the access layer transmission device, and the device incapable of providing service, which are connected in series, respectively, specifically: and sequentially carrying out power failure detection on the moving loop, and/or high-temperature detection on the moving loop, and/or off-pipe detection on the transmission equipment of the core layer, the transmission equipment of the L2/L3 layer, the transmission equipment of the convergence layer and the transmission equipment of the access layer, and/or loss alarm detection on the transmission signal, and/or degradation detection on the transmission performance. In this embodiment, the alarm diagnoses of these devices are not performed simultaneously but are detected sequentially, and the detection priority may preferably be power failure of the moving loop or high temperature of the moving loop > transmission disconnection > transmission signal loss > transmission performance degradation, as shown in fig. 7, the diagnosis process specifically includes the following steps:

step S1801: detecting core layer equipment in the dynamic topology, sequentially checking whether a machine room of the equipment has power failure or high-temperature alarm of a moving ring, if not, detecting whether the equipment has transmission off-pipe alarm, if not, detecting whether a transmission loss alarm exists at a corresponding port of the equipment, and if not, detecting whether a performance index degradation condition exists at the corresponding port of the equipment.

The detection priority may preferably be dynamic loop power failure or dynamic loop high temperature > transmission off-pipe > transmission signal loss > transmission performance degradation, and when a fault is detected, other detections are stopped, the detection and diagnosis process for the core layer device is exited, and an alarm signal is generated.

Step S1802: detecting L2/L3 layer equipment in a dynamic topology, sequentially checking whether a machine room of the equipment has power failure of a moving ring or high-temperature alarm, if not, detecting whether the equipment has transmission off-pipe alarm, if not, detecting whether a transmission loss alarm exists at a corresponding port of the equipment, and if not, detecting whether a performance index degradation condition exists at the corresponding port of the equipment.

The detection priority may preferably be moving-ring power failure or moving-ring high temperature > transmission disconnection > transmission signal loss > transmission performance degradation, and when a fault is detected, other detection is stopped, the detection and diagnosis process for the L2/L3 layer device is exited, and an alarm signal is generated.

It should be noted that: when there is no L2/L3 layer in the network structure, step S1802 can also be omitted.

Step S1803: detecting convergence layer equipment in a dynamic topology, sequentially checking whether a machine room of the equipment has power failure or high-temperature alarm of a moving ring, if not, detecting whether the equipment has transmission off-pipe alarm, if not, detecting whether a transmission loss alarm exists at a corresponding port of the equipment, and if not, detecting whether a performance index degradation condition exists at the corresponding port of the equipment.

The detection priority can preferably be dynamic ring power failure or dynamic ring high temperature > transmission disconnection > transmission signal loss > transmission performance degradation, when a fault is detected, other detections are stopped, the detection and diagnosis process of the convergence layer equipment is quitted, and an alarm signal is generated.

Step S1804: detecting access layer transmission equipment which has a connection relation with a deputy base station in the dynamic topology, sequentially checking whether a machine room of the equipment has power failure of a moving ring or high-temperature alarm, if not, detecting whether the equipment has transmission offline alarm, if not, detecting whether a port corresponding to the equipment has transmission loss alarm, and if not, detecting whether a port corresponding to the equipment has performance index degradation condition.

The detection priority may preferably be dynamic ring power failure or dynamic ring high temperature > transmission off-pipe > transmission signal loss > transmission performance degradation, and when a fault is detected, other detection is stopped, the detection and diagnosis process for the access layer device is exited, and an alarm signal is generated.

It can be understood that: the detection sequence of fault location and the content to be detected are not limited to the above description, and may also be other detection sequences and other contents that affect the fallback of the base station, and are not described herein again.

In other embodiments, the reason for the fallback of the base station may occur in itself, so that the fault locating the core layer transmission device, the L2/L3 layer transmission device, the convergence layer transmission device, the access layer transmission device and the device incapable of providing service, which are connected in series, further includes: and performing power failure detection or high-temperature alarm detection on the machine room to which the equipment which cannot provide service belongs.

Accordingly, the diagnostic procedure should also include:

and step S1805, when the out-of-service base station in the dynamic topology is detected, checking whether a machine room of the out-of-service base station has power failure or high-temperature alarm. If so, the diagnostic process is exited and an alarm signal is generated.

In the preferred embodiment of the invention, the core layer transmission equipment, the L2/L3 layer transmission equipment, the convergence layer transmission equipment, the access layer transmission equipment and the quit-service base station in the dynamic topology are detected from top to bottom in sequence, and when the uplink equipment detects a fault, the detection of the downlink equipment is interrupted, so that the fault reason can be quickly positioned, and the resources required by the detection are saved.

Fig. 8 is a flowchart illustrating the sub-steps of performing fault location on the core layer transmission device, the L2/L3 layer transmission device, the convergence layer transmission device, the access layer transmission device, and the device incapable of providing service, which are connected in series, in another embodiment of the present invention, as shown in fig. 8, after step S1805 in the previous embodiment, the method further includes:

step S1806: and respectively carrying out fault positioning on equipment which is connected in series with the access layer transmission equipment of each access ring, generating alarm signals and summarizing all the alarm signals.

The dynamic topology generated in the above step may include a plurality of access rings, each access ring also has a core layer transmission device for uplink, the L2/L3 layer transmission device and a convergence layer transmission device for uplink, and a fallback base station for downlink. The access rings and the devices connected with the access rings can form a plurality of access networks, so that the dynamic topology in the embodiment of the invention can be divided into a plurality of access network topologies, and then the step sequentially starts the diagnosis process in the step for each access network topology to respectively perform fault location on the access network topologies. With continued reference to FIG. 7, when an alarm is detected in a diagnostic procedure, an alarm signal is generated and pushed into the root cause queue. The alarm signal includes alarm information detected in the diagnosis process and the number of the out-of-service base stations connected in series in the local access network topology, the alarm information may be regarded as a fault cause, and the number of the out-of-service base stations may be regarded as an influence range of the alarm. And after all the access network topologies complete the diagnosis process, summarizing the alarm signals in the root result queue.

Step S1807: and determining the number of devices which cannot provide service and correspond to each alarm signal.

As described above, the number of fallback base stations corresponding to the respective alarm signals is counted.

In this step, the alarm signals collected in step S1806 are sorted according to the number of the out-of-service base stations included therein, and several alarms and failure reasons with a larger number of out-of-service base stations may be selected for performing fault location.

In addition, when fault location is carried out, the embodiment of the invention carries out fault location on the core layer transmission equipment, the convergence layer transmission equipment, the access layer transmission equipment and the equipment which cannot provide service in sequence from top to bottom, and the detection of the lower connection equipment is interrupted after the upper connection equipment detects the fault, so that the fault reason can be quickly located, and the resources required by detection are saved.
