Description

Fault detection method and device

Technical Field

The present application relates to the field of communications, and more particularly, to a method of fault detection and an apparatus thereof.

Background

In a wireless communication system, a base station is usually connected to a network management system as a wireless access node, and is maintained by the network management system.

However, for some reasons, for example, due to a fault of an interface board of the base station, a fault of an interface optical module, a fault of a transmission link, etc., a maintenance link between the base station and the network management system may be interrupted; for another example, power failure of the base station may be caused by a power failure, a power interruption, or other failure of the base station. Whether the maintenance link between the base station and the network management system is interrupted or the base station is powered off, the base station is separated from the management of the network management system. At present, there is still room for improvement in how to better handle base stations that are out of management of the network management system.

Disclosure of Invention

The embodiment of the application provides a fault detection method and a fault detection device, which can provide powerful support for processing base stations which are different from the management type of a network management system in a targeted manner, and improve the efficiency of processing the base stations which are not managed by the network management system.

In a first aspect, a method for fault detection is provided, including: the first base station detects the link abnormity between the first base station and a network management system; the first base station sends first information to a second base station managed by the network management system, and at least one item of time domain resources or frequency domain resources where the first information is located or the content of the first information indicates that the link is abnormal.

For example, the first base station may detect a link anomaly between the first base station and the network management system (specifically, may be an element management entity included in the network management system) by sending periodic detection information (for example, "heartbeat packets") at a certain time interval.

In addition, in one possible implementation manner, the first information may indicate, through a preset frame number, a base station with a link abnormality with the network management system (that is, the first base station is a base station with a link abnormality with the network management system). For example, the first base station may transmit the sequence in a Guard Period (GP) region of each radio frame with a frame number of 125, where the frame number of 125 only represents that the first base station is a link anomaly with the network management system.

In another possible implementation manner, the first information may indicate, through a preset transmission duration, that there is a base station with an abnormal link with the network management system (i.e., the first base station is a base station with an abnormal link with the network management system). For example, the first base station may send the first information continuously for 3 minutes, and the duration of 3 minutes only represents that the first base station is a link anomaly with the network management system.

The time domain resource (for example, a preset frame number, a preset transmission duration, a preset number of repeated transmissions, or a preset time interval between two adjacent transmissions) where the first information is located is preset by the first base station and the second base station.

In yet another possible implementation manner, the first information may indicate, through preset content, that there is a base station with an abnormal link with the network management system (i.e., the first base station is a base station with an abnormal link with the network management system). For example, the first information may include the content of a preset bit, thereby indicating that the first base station is a link abnormality with the network management system.

The content of the first information (e.g., the content of the preset bit) is preset by the first base station and the second base station.

It should be understood that the above three possible implementation manners may exist alone or in combination with each other, and the present application is not limited thereto.

Based on the above solution, a first base station managed by the network management system may send first information to a second base station managed by the network management system to indicate a link abnormality between the first base station and the network management system in the presence of the link abnormality with the network management system, and further, the second base station may determine the link abnormality between the base station managed by the network management system and the network management system according to at least one of a time domain resource or a frequency domain resource where the first information is located, or a content of the first information, send information indicating the link abnormality between the base station managed by the network management system and the network management system to the network management system, and the network management system may send information indicating the link abnormality between the base station managed by the network management system and the network management system according to the information managed by the first base station out of the network management system and the information indicating the link abnormality between the base station managed by the network management system and the network management system, a link anomaly between the first base station and the network management system is determined. Therefore, the network management system can not only detect that the first base station is out of the management of the network management system, but also determine the fault type of the first base station out of the management of the network management system (for example, the link between the first base station and the network management system is abnormal), so that powerful support is provided for processing base stations out of different management types of the network management system in a targeted manner, and the efficiency of processing the base stations out of the management of the network management system is improved.

With reference to the first aspect, in some implementations of the first aspect, the first base station receives second information from the second base station, where at least one of a time domain resource or a frequency domain resource where the second information is located, or a content of the second information indicates a processing policy for the link exception.

In one possible implementation manner, the second information may indicate a handling policy of the link exception through a preset frame number. For example, the first base station may transmit the sequence in the guard interval of each radio frame with frame number 115, where the frame number 115 only indicates that the first base station is controlled not to provide service.

In another possible implementation manner, the second information may indicate a handling policy of the link exception through a preset sending duration. For example, the first base station may send the second information continuously for 2 minutes, and the duration of 2 minutes only represents that the first base station is controlled not to provide service (e.g., all cells of the first base station may be blocked, so that the first base station stops providing service).

The time domain resource (for example, a preset frame number, a preset transmission duration, a preset number of repeated transmissions, or a preset time interval between two adjacent transmissions) in which the second information is located is preset by the first base station, the second base station, and the network management system (specifically, may be a network element management entity included in the network management system) together.

In yet another possible implementation manner, the second information may indicate a handling policy of the link exception through preset content. For example, the second information may include the content of a preset bit, thereby instructing the first base station to restart.

Wherein, the content of the second information (for example, the content of the preset bit) is preset by the first base station, the second base station, and the network management system (specifically, may be a network element management entity included in the network management system) together.

Based on the above scheme, the first base station may receive the second information from the second base station, and determine a processing policy for the link exception according to at least one of a time domain resource or a frequency domain resource where the second information is located, or a content of the second information (for example, different processing policies for the link exception may be characterized according to different time domain resources or different frequency domain resources where the second information is located, or different contents of the second information). Furthermore, the first base station which is out of the management of the network management system can be controlled to perform operations such as non-service provision or restart.

In a second aspect, a method for fault detection is provided, including: the second base station receives third information from the network management system, and the third information informs that the fault type of the base station which is out of the management of the network management system is detected; the second base station receives first information from the first base station, and the first base station belongs to the base station which is not managed by the network management system; the second base station determines that the link between the base station which is separated from the management of the network management system and the network management system is abnormal according to the time domain resource or the frequency domain resource where the first information is located or the content of the first information, wherein the fault type of the base station which is separated from the management of the network management system comprises the link abnormality.

Based on the above scheme, after receiving the third information, the second base station starts to detect the fault type of the base station which is away from the management of the network management system, and when receiving the first information from the first base station, the second base station can determine that the base station which is away from the management of the network management system exists through the time domain resource or the frequency domain resource where the first information is located, or the content of the first information, and the link between the base station and the network management system is abnormal, so that the base station can report to the network management system subsequently, and the network management system can determine that the fault type that the first base station is away from the management of the network management system is abnormal. Therefore, the method can not only detect the management of the first base station which is separated from the network management system, but also determine the fault type of the first base station which is separated from the management of the network management system (for example, the link between the first base station and the network management system is abnormal), thereby providing a powerful support for processing base stations which are separated from the management type of the network management system in a targeted manner, and improving the efficiency of processing the base stations which are separated from the management of the network management system.

With reference to the second aspect, in some implementations of the second aspect, the second base station sends fourth information to the network management system, where the fourth information indicates that the link is abnormal.

Based on the scheme, the second base station can send information indicating link abnormity to the network management system, and the network management system can determine the link abnormity between the first base station and the network management system according to the information and the information that the first base station is separated from the management of the network management system.

With reference to the second aspect, in some implementations of the second aspect, the second base station receives fifth information from the network management system, where the fifth information is used to send information indicating a processing policy for the link exception; and the second base station sends second information to the first base station according to the fifth information, wherein at least one item of time domain resources or frequency domain resources where the second information is located or the content of the second information indicates a processing strategy of the link abnormity.

Based on the above scheme, the second base station may receive the fifth information from the network management system, and send (for example, send in a broadcast mode, where an object of the broadcast includes the first base station) the second information, and the first base station may determine a processing policy for the link anomaly through at least one of a time domain resource or a frequency domain resource where the second information is located, or a content of the second information (for example, different processing policies for the link anomaly may be characterized according to different time domain resources or different frequency domain resources where the second information is located, or different contents of the second information). Furthermore, the first base station which is out of the management of the network management system can be controlled to perform operations such as non-service provision or restart.

In a third aspect, a method for fault detection is provided, including: the network management system sends third information to at least one base station, and the third information informs of detecting the fault type of the base station which is not managed by the network management system; under the condition that the network management system receives fourth information from part or all of the base stations in the at least one base station, the network management system determines that a link between the first base station and the network management system is abnormal according to the fourth information and information that the first base station is out of management of the network management system, wherein the fourth information indicates that the link between the base station out of management of the network management system and the network management system is abnormal, and the first base station belongs to the base station out of management of the network management system.

Based on the scheme, after the network management system sends the information notifying that the detection is the fault type of the base station which is out of the management of the network management system to at least one base station, the network management system receives the fourth information from part or all of the base stations in the at least one base station, and determines the link abnormity of the first base station and the network management system through the fourth information and the information that the first base station is out of the management of the network management system. Furthermore, the method can not only detect that the first base station is out of the management of the network management system, but also determine the fault type of the first base station out of the management of the network management system (for example, the link between the first base station and the network management system is abnormal), thereby providing a powerful support for processing base stations out of different management types of the network management system in a targeted manner, and improving the efficiency of processing the base stations out of the management of the network management system.

With reference to the third aspect, in certain implementations of the third aspect, in a case that the network management system receives sixth information from the at least one base station, the network management system determines that the first base station is powered down according to the sixth information and information that the first base station is out of management of the network management system, where the sixth information indicates that there is a powered down base station, the first base station belongs to the powered down base station, and the powered down base station belongs to the base station out of management of the network management system.

Based on the scheme, the network management system can determine that the first base station is powered down through the sixth information and the information that the first base station is separated from the management of the network management system. Furthermore, the method can not only detect that the first base station is out of the management of the network management system, but also determine the fault type (for example, the first base station is powered off) of the first base station out of the management of the network management system, thereby providing a powerful support for processing base stations out of different management types of the network management system in a targeted manner and improving the efficiency of processing the base stations out of the management of the network management system.

With reference to the third aspect, in certain implementations of the third aspect, the network management system sends, to the at least one base station, fifth information used for sending information indicating a handling policy of a link exception between the base station that is away from management by the network management system and the network management system.

Based on the above scheme, the network management system sends, to the at least one base station, fifth information indicating a processing policy for a link anomaly between the base station that is not managed by the network management system and the network management system, and then the at least one base station may send, to the first base station, second information (for example, sending the second information in a broadcast manner), where the first base station may determine the processing policy for the link anomaly through at least one of a time domain resource or a frequency domain resource where the second information is located or a content of the second information (for example, different time domain resources or different frequency domain resources where the second information is located may be used, or different contents of the second information may represent different processing policies for the link anomaly). Therefore, the network management system can control the first base station which is out of the management of the network management system to perform operations such as no service provision or restart.

With reference to the third aspect, in some implementations of the third aspect, the network management system determines the at least one base station according to the neighboring cell configuration information of the first base station.

With reference to the third aspect, in certain implementations of the third aspect, the network management system detects that the first base station is out of management of the network management system.

For example, the network management system may detect that the first base station is away from the management of the network management system by sending periodic detection information (e.g., "heartbeat packets") at certain time intervals.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The technical scheme provided by the application can be applied to various communication systems, such as: a fifth generation (5G) or New Radio (NR) system, a Long Term Evolution (LTE) system, a LTE Time Division Duplex (TDD) system, and the like. The technical scheme provided by the application can also be applied to future communication systems, such as a sixth generation mobile communication system. The technical solution provided in the present application may also be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, Machine Type Communication (MTC), and internet of things (IoT) communication systems or other communication systems.

A brief introduction of a network architecture suitable for use in the present application is first provided below.

As an example, fig. 1 shows a schematic diagram of a wireless network architecture. As shown in fig. 1, the network management system includes a Network Management (NM) layer and an Element Management (EM) layer, and the Network Element (NE) layer includes a base station. The EM layer and the NE layer are a southbound interface, the NM layer and the EM layer are a northbound interface, and the NE layer may include at least one base station and at least one core network device. For example, a network management entity, a network element management entity, base station #1, and base station #2 as shown in fig. 1. The network element management entity and the network management entity can directly communicate, the base station #1 and the base station #2 can directly communicate, and the base station #1 and the base station #2 can also directly communicate with the network management system respectively.

A network management entity (may also be referred to as a network manager, NM) included in the NM layer is a management system responsible for the operation, management, and maintenance functions of the network, so that resources in the network system are better utilized, and the NM layer is a set for implementing various network management functions on the basis of a network management platform.

The network management entity can provide a function package of the end user, belongs to the management layer, is supported by the network element management system, but can also directly access the network element. The communication interfaces of the network management entity are all open and standardized interfaces, and support management network elements of multiple suppliers and multiple technologies.

An element management entity (also referred to as an Element Manager (EM)) included in the EM layer is responsible for managing one or more elements of a certain class in a wireless network. The network element management entity allows the user to manage all the features of each network element individually, managing the communication between the network elements.

The network element management entity may provide a package of functions for managing end users associated with network element types, which may be divided into two main categories: a network element management function and a subnet management function.

It should be understood that the network management system in the embodiment of the present application may include the network element management entity and the network management entity shown in fig. 1, and is mainly responsible for controlling the neighboring base stations of the base station that is not managed by the network management system to perform sequence detection and reception, collecting information reported by the neighboring base stations, and performing comprehensive judgment on the fault type of the base station that is not managed by the network management system according to the collected data; and informing the base station which is not managed by the network management system to carry out appointed operation through the normal adjacent base station.

In addition, the base station may be any device having a wireless transceiving function. May include wireless network devices in a 3rd generation partnership project (3 GPP) network and may also include access points in non-3GPP (non-3GPP) networks. The apparatus includes, but is not limited to: an evolved Node B (eNB), a BaseBand Unit (BBU), and may also be 5G, such as a gNB in an NR system, and one or a group (including multiple antenna panels) of base stations in a 5G system, or may also be a network Node forming the gNB or a transmission point, such as a BaseBand Unit (BBU), or a Distributed Unit (DU), and the like, or a base station in a next-generation communication 6G system, and the like. The embodiment of the present application does not limit the specific technology and the specific device form used by the base station.

In this application, the base station includes a Base Band Unit (BBU) and a Remote Radio Unit (RRU), and may control the RRU to receive and transmit information through a BBU-RRU interface, or receive information of the BBU and send the information through an air interface, or receive the information through the air interface and transmit the information back to the BBU through the BBU-RRU interface.

In a wireless network, a base station may serve as a wireless access node, and is usually maintained by a remote network management system. However, the network management system may not be able to maintain the base station for some reason, for example, because the utility power is interrupted or the transmission is interrupted, the corresponding process needs to be performed manually.

Fig. 2 is a schematic diagram of a link between a base station and a network management system. As shown in fig. 2, when maintenance interruption occurs due to a failure of an interface board of the base station, a failure of an interface optical module, a failure of a transmission link, or an interruption of the utility power, the base station #2 may become out of a management state of the network management system (including the element management entity). Therefore, the type of the base station #2 fault which is not managed by the network management system is accurately judged, and the efficiency of solving the base station fault can be obviously improved.

Currently, there are two methods for determining the type of a fault of a base station that is not managed by a network management system, which are respectively:

1. when a certain base station is out of management of the network management system due to some reasons (for example, a fault of an interface single plate of the base station, a fault of an interface optical module, a fault of a transmission link and the like), if the base station out of management of the network management system can still maintain communication with other normal base stations, the fault type of the base station out of management of the network management system is that a link between the base station and the network management system is interrupted, and if the base station out of management of the network management system cannot maintain communication with other normal base stations, the fault type of the base station out of management of the network management system is power failure;

2. after a certain base station is out of management of the network management system due to some reasons (for example, power supply abnormality, power supply interruption and other faults of the base station), the deactivation of a cell covered by the base station managed by the network management system can be delayed, so that a terminal device of an adjacent cell can detect a signal of the cell covered by the base station managed by the network management system, and further, the terminal device can judge whether transmission power exists in the base station managed by the network management system by collecting a measurement report of the terminal device, and if so, the reason that the base station is out of management of the network management system is link interruption with the network management system; if not, the base station is powered down.

However, in the first method, the transmission link between the base stations is often shared with the network management system, and when the link between the base station out of the management of the network management system and the network management system is interrupted, the link between the base station out of the management of the network management system and other base stations is also interrupted, so that it is impossible to judge whether the fault type of the base station out of the management of the network management system is the link interruption with the network management system or the power failure; in the second method, it cannot be guaranteed that a suitable terminal device can be found at a suitable time, and in addition, the terminal device may also detect a physical cell identifier of a cell covered by a normal base station, which causes confusion and inaccurate detection results.

In view of the above, embodiments of the present application provide a method and an apparatus for fault detection, which can effectively solve the above problems.

The method and apparatus for fault detection provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided in this application may be applied to the wireless network architecture shown in fig. 1, which is not limited.

It should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 3 shows a schematic diagram of a method 300 for fault detection according to an embodiment of the present application. As shown in fig. 3, the method 300 may include the steps of:

s301, the first base station detects link abnormity between the first base station and the network management system.

For example, the first base station may detect a link anomaly between the first base station and the network management system by sending periodic detection information (e.g., "heartbeat packets") at certain time intervals. The link between the first base station and the network management system may be abnormal, and the link may include a fault type such as an interface single board fault, an interface optical module fault, and a transmission link fault.

For example, if the first base station sends periodic detection information to the network management system at a certain time interval and does not receive response information of the network management system about the detection information, it may be determined that the link between the first base station and the network management system is abnormal.

It should be understood that the link anomaly between the first base station and the network management system in the present application may be a link anomaly between the first base station and an element management entity (included in the network management system).

S302, the network management system sends third information to the second base station. Correspondingly, the second base station receives third information from the network management system.

Wherein the third information is used for notifying the detection of the fault type of the base station which is out of the management of the network management system.

For example, the failure type of the base station that is not managed by the network management system may include a link between the base station and the network management system is abnormal, or a failure type such as a power failure of the base station.

In addition, after determining that the link between the first base station and the network element management entity is abnormal, the network element management entity included in the network management system may alarm the network management entity (included in the network management system) of the operator through the northbound interface.

It should be understood that the second base station belongs to at least one base station described below, and S302 can also be described as the network management system sending the third information to the at least one base station. Correspondingly, the at least one base station receives third information from the network management system.

Further, to detect the first base station, the method 300 may further include: and the network management system determines at least one base station according to the adjacent area configuration information of the first base station.

Specifically, the network management system may determine at least one base station according to the neighboring cell configuration information of the first base station, and send the third information to the at least one base station, so that the at least one base station detects a base station that is away from the management of the network management system. Wherein the at least one base station comprises a second base station.

Optionally, the action performed by the network management system in the present application may be performed by a network element management entity included in the network management system.

Further, the method 300 may further include: the network management system detects that the first base station is out of management of the network management system.

For example, the network management system may detect that the first base station is out of management of the network management system by sending periodic detection information (e.g., "heartbeat packets") at certain time intervals.

For example, if the network management system sends periodic detection information to the first base station at a certain time interval and does not receive response information of the first base station about the detection information, it may be determined that the first base station is out of management of the network management system.

S303, the first base station sends the first information to the second base station. Correspondingly, the second base station receives the first information from the first base station according to the third information.

At least one of the time domain resource or the frequency domain resource where the first information is located, or the content of the first information may indicate that a link between the first base station and the network management system is abnormal.

Specifically, after detecting that the link between the first base station and the network management system is abnormal, the first base station may send first information to the second base station, where the link between the first base station and the network management system is abnormal, and the link between the first base station and the network management system is indicated by at least one of a time domain resource or a frequency domain resource where the first information is located, or a content of the first information. Since the second base station receives the first information in a broadcast manner, the second base station cannot perceive that the first information is sent by the first base station, and furthermore, the second base station can only determine that there is a base station which is out of management of the network management system and a link between the base station and the network management system is abnormal.

In one possible implementation manner, the first information may indicate a link abnormality between the first base station and the network management system through a preset frame number. For example, the first base station may transmit the sequence in the guard interval of each radio frame with frame number 125, where the frame number 125 only represents the base station with link abnormality with the network management system (i.e. the first base station with link abnormality with the network management system).

In another possible implementation manner, the first information may indicate a link abnormality between the first base station and the network management system through a preset transmission duration (for the second base station, only represents a link abnormality between a base station out of management of the network management system and the network management system). For example, the first base station may send the first information continuously for 3 minutes, and the continuous time of 3 minutes only represents the link between the first base station and the network management system is abnormal.

The time domain resource (for example, a preset frame number, a preset transmission duration, a preset number of repeated transmissions, or a preset time interval between two adjacent transmissions) where the first information is located is preset by the first base station and the second base station (at least one base station) together.

In yet another possible implementation manner, the first information may indicate, through preset content, a link anomaly between the first base station and the network management system (for the second base station, only the link anomaly between the base station out of management of the network management system and the network management system is represented). For example, the first information may include the content of a preset bit, thereby indicating that the link between the first base station and the network management system is abnormal.

The content of the first information (e.g., the content of the preset bit) is preset by the first base station and the second base station (at least one base station) in common.

It should be further understood that, in the above solution, the execution sequence of S303, S302, and S302 may be executed first, and the execution sequence of S302 and S303 is not limited.

S304, the second base station determines the link abnormity between the base station which is not managed by the network management system and the network management system according to the time domain resource or the frequency domain resource where the first information is located or the content of the first information.

Specifically, the second base station may determine the link abnormality between the base station which is not managed by the network management system and the network management system according to at least one of the time domain resource or the frequency domain resource where the first information is located as described in S303 above, or the content of the first information.

S305, under the condition that the network management system receives fourth information from part or all of the base stations in at least one base station, the network management system determines that a link between the first base station and the network management system is abnormal according to the fourth information and the information that the first base station is separated from the management of the network management system.

The fourth information indicates that a link between the base station which is managed by the network management system and the network management system is abnormal, and the first base station belongs to the base station which is managed by the network management system.

Specifically, after determining that the link between the base station managed by the network management system and the network management system is abnormal, some or all of the at least one base station (e.g., the second base station) may send fourth information to the network management system to inform the network management system of the link between the base station managed by the network management system and the network management system.

Alternatively, if at least one base station (e.g., a second base station) does not receive the first information, the at least one base station (e.g., the second base station) may determine that there is a powered-down base station and transmit sixth information to the network management system, the sixth information indicating that there is a powered-down base station. In this way, after receiving the sixth information from at least one base station (e.g., the second base station), the network management system may determine that the first base station is powered down based on the sixth information and information that the first base station is out of management of the network management system. Wherein the first base station belongs to a power-down base station, and the power-down base station belongs to a base station which is separated from the management of the network management system

In another possible implementation manner, after receiving the first information from the first base station, some or all of the base stations (e.g., the second base station) in at least one base station do not determine that the link between the first base station and the network management system is abnormal according to the time domain resource or the frequency domain resource where the first information is located, or the content of the first information, but at least one of the time domain resource information where the first information is located, the frequency domain resource information where the first information is located, or the content of the first information is sent to the network management system, and the network management system determines that the link between the base station which is away from the management of the network management system and the network management system is abnormal according to at least one of the time domain resource information where the first information is located, the frequency domain resource information where the first information is located, or the content of the first information. Furthermore, after determining that the link between the base station out of the management of the network management system and the network management system is abnormal, the network management system may determine that the link between the first base station and the network management system is abnormal by combining the information that the first base station is out of the management of the network management system.

The information (for example, a frame number) of the frequency domain resource where the first information is located, the information (for example, a persistent transmission time) of the time frequency resource where the first information is located, or the content (for example, the content of a preset bit) of the first information is preset jointly by the first base station, the second base station (at least one base station), and the network management system (specifically, the network element management entity included in the network management system).

Optionally, the method 300 may further include: the network management system transmits the fifth information to the at least one base station.

The fifth information is used for sending information indicating a processing strategy of link abnormity between the base station which is not managed by the network management system and the network management system. For example, the processing policy may include controlling the first base station not to provide service, or controlling the first base station to restart.

Specifically, the network management system may transmit the fifth information to at least one base station (e.g., the second base station) after determining the failure type of the first base station, so that the at least one base station (e.g., the second base station) may transmit information indicating a handling policy of the link abnormality.

For example, at least one base station (e.g., the second base station) may transmit the fifth information in a broadcast form. Wherein the object transmitted in the broadcast form includes the first base station.

Optionally, the method 300 may further include: and the at least one base station sends the second information to the first base station according to the fifth information.

Wherein at least one of the time domain resource or the frequency domain resource where the second information is located or the content of the second information indicates a processing strategy for link abnormity between the base station and the network management system which are not managed by the network management system. Further, the processing policy may include controlling the first base station not to provide service (e.g., may cause the first base station to cease providing service by blocking all cells of the first base station), or restarting.

Alternatively, at least one base station (e.g., a second base station) may transmit the second information in a broadcast form, and the first base station belongs to an object to which the at least one base station (e.g., the second base station) broadcasts the second information.

Wherein, at least one base station (for example, the second base station) does not perceive that the base station which is away from the management of the network management system is the first base station, so, for at least one base station (for example, the second base station), at least one of the time domain resource or the frequency domain resource where the second information is located, or the content of the second information indicates a handling policy of the link anomaly between the base station which is away from the management of the network management system and the network management system; for the first base station, at least one of the time domain resource or the frequency domain resource where the second information is located or the content of the second information indicates a processing strategy for link abnormity between the first base station and the network management system.

In another possible implementation manner, the second information may indicate a handling policy of the link exception through a preset sending duration. For example, the first base station may send the second information continuously for 2 minutes, and the duration of 2 minutes only represents that the first base station is controlled not to provide service.

The time domain resource (for example, a preset frame number, a preset transmission duration, a preset number of repeated transmissions, or a preset time interval between two adjacent transmissions) in which the second information is located is preset jointly by the first base station, the second base station (at least one base station), and the network management system (specifically, the network element management entity included in the network management system).

Wherein, the content of the second information (for example, the content of the preset bit) is preset jointly by the first base station, the second base station (at least one base station), and the network management system (specifically, may be a network element management entity included in the network management system).

Based on the above solution, in one aspect, a first base station managed by a network management system may send first information to at least one base station (e.g., a second base station) to indicate a link abnormality in case of the link abnormality between the first base station and the network management system, the at least one base station (e.g., the second base station) may determine the link abnormality between the base station managed by the network management system and the network management system according to at least one of a time domain resource or a frequency domain resource where the first information is located or a content of the first information after receiving third information notifying detection from the network management system (e.g., the link abnormality may be characterized according to a different time domain resource or a different frequency domain resource where the first information is located or a different content of the first information), and send fourth information indicating the link abnormality between the base station managed by the network management system and the network management system to the network management system, the network management system can determine that a link between the first base station and the network management system is abnormal according to the fourth information and the information that the first base station is separated from the management of the network management system; on the other hand, after receiving the third information notifying that the failure type of the base station out of the management of the network management system is detected by the at least one base station (e.g., the second base station), and not receiving the first information, the at least one base station (e.g., the second base station) may send sixth information indicating that there is a base station with power failure to the network management system, and the network management system may determine that the first base station has power failure according to the sixth information and the information that the first base station is out of the management of the network management system. Furthermore, the network management system can detect that the first base station is out of the management of the network management system, and can determine the fault type of the first base station out of the management of the network management system, so that a powerful support is provided for processing base stations out of different management types of the network management system in a targeted manner, and the efficiency of processing the base stations out of the management of the network management system is improved.

In addition, the network management system may send, to at least one base station (e.g., a second base station), information indicating a processing policy for the link exception, so that the at least one base station (e.g., the second base station) may send (e.g., send in a broadcast manner) the second information to the first base station, and the first base station controlling the management leaving the network management system may perform operations such as not providing a service or restarting, through a time domain resource or a frequency domain resource in which the second information is located, or at least one of the content of the second information indicating a processing policy for the link exception (e.g., according to a different time domain resource or a different frequency domain resource in which the second information is located, or different content of the second information may represent a different processing policy for the link exception).

It is to be understood that, in the above embodiments of the method, the method and the operation implemented by the network management system may also be implemented by software available to the computer-installed network management system, the method and the operation implemented by the first base station may also be implemented by a component (e.g., a chip or a circuit) available to the first base station, the method and the operation implemented by the second base station (at least one base station), and the component (e.g., a chip or a circuit) available to the second base station (at least one base station).
