Technical Field

Background

Long Term Evolution (LTE) is used as a new generation wireless network communication technology, a service does not have a controller node, and a base station directly accesses a core network through a Mobility management entity/access Gateway (MME/S-GW). Therefore, Operation and maintenance of a base station (evolved node B, eNB for short) in an LTE network mainly centrally manages each base station distributed in the network through an Operation and maintenance Management system (OSS), an Operation and maintenance channel between the OSS and the base station is an Operation and Management (OAM) channel, and specifically, refer to an Operation and maintenance architecture diagram of the LTE network shown in fig. 1. The OSS is generally deployed in a customer premises, and the OSS can conveniently perform operation maintenance, service operation status check, log information file transfer, and the like on base stations distributed at a remote end. Compared with other wireless networks, the LTE network has higher requirements on the robustness of OSS and OAM channels, and once an OSS loses connection with 1 or more base stations, management and control are lost for the base stations, and the service operation of the base stations is unknown. As shown in fig. 2, when the OSS and eNB2 lose communication link, the traffic operation status of eNB2 is unknown, and eNB2 is called a deputy base station; once a managed base station exists in an LTE network, it means that the current operating state of the base station is agnostic.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A base station, to which embodiments of the present invention relate, may refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The base station may be configured to translate received air frames and IP packets into and out of communication with each other as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. In addition, the base station may coordinate management of attributes for the air interface. Optionally, the base station may be an evolved Node B (NodeB or eNB or e-NodeB) in LTE.

The method related to the embodiment of the invention is applicable to any mobile communication network operation and maintenance system, for example, the LTE network operation and maintenance system shown in fig. 3. The mobile communication network operation and maintenance system can comprise an OSS, a second base station and a first base station, wherein the second base station and the first base station are provided with a communication link (such as an X2 link). In the embodiment of the present invention, the second base station is a base station that can normally communicate with the OSS, and the second base station may be one or multiple base stations; the first base station is an offline base station, and the number of the first base stations may be one or multiple, that is, as long as the base station loses communication connection with the OSS and has a normal communication link with the second base station, the first base station may be referred to as the first base station.

The method provided by the embodiment of the invention aims to solve the technical problem that in the prior art, when an unmanaged base station exists in a mobile communication network operation and maintenance system, an OSS (operation system) cannot timely determine the service operation state of the unmanaged base station, so that the operation and maintenance of a mobile communication network are unstable.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 4 is a flowchart illustrating a first method for detecting a service state of a base station according to an embodiment of the present invention. The embodiment relates to a specific process of obtaining a service state of a first base station by sending a start control command to a second base station when an OSS detects that an offline base station (i.e. the first base station) exists in a mobile communication network operation and maintenance system where the OSS is located. The following mobile communication network operation and maintenance system may be exemplified by the LTE network operation and maintenance system shown in fig. 3. As shown in fig. 4, the method includes:

s101: the OSS determines that the first base station is disconnected from communication with the OSS.

Specifically, the OSS may monitor, in real time, an operation state of a base station managed by the OSS in the mobile communication network operation and maintenance system by using a monitoring mechanism of the OSS. Optionally, when the OSS determines that the service state of the first base station cannot be obtained through the OAM channel or when the OSS monitors related warning information that is not in contact with the first base station, the OSS determines that the current first base station is disconnected from the OSS, that is, determines that the first base station is an offline base station.

S102: the OSS sends a starting control command to the second base station; wherein the start control command is used for instructing the second base station to send a first resource status request message to the first base station; the first resource status request message includes a first registration request cell, where the first registration request cell is used to instruct the first base station to measure the service status of the first base station, and send the service status to the second base station in a resource status report.

Specifically, when the OSS determines that the first base station is an offline base station, in order to obtain a service state of the first base station in a short time, the OSS sends a start control command to the second base station, where the start control command is used to instruct the second base station to send a first resource state request message to the first base station. Optionally, the start control command may be a message with any frame structure, or may be a control command with any format, and as long as the message or the control command sent by the OSS to the second base station has a function of "instructing the second base station to send the first resource status request message to the first base station", both the message and the control command may be the start control command.

After receiving the start control command sent by the OSS, the second base station initiates a Resource status query procedure, i.e. initiates a Resource status reporting Initiation procedure, to the first base station according to the indication of the start control command and a 3GPP 36423 protocol. Specifically, the second base station sends a first resource status request message to the first base station according to the indication of the start control command, where the first resource status request message carries a first registration request cell, and the first registration request cell is used to indicate the first base station to measure the service status of the first base station. Optionally, the first RESOURCE STATUS REQUEST message may be a RESOURCE STATUS REQUEST message in a protocol of 3GPP 36423, and the first Registration REQUEST cell may be a Registration REQUEST cell in the RESOURCE STATUS REQUEST message, where the Registration REQUEST cell takes the value of "start".

The second base station and the first base station can normally communicate because of the communication link between the second base station and the first base station. Therefore, the first base station may receive the first resource status request message sent by the second base station. After the first base station receives the first resource status request message sent by the second base station, the first base station measures its own service status according to the indication of the first registration request cell in the first resource status request message, for example: checking the service log of the first base station, measuring the current time frequency resource utilization rate of the first base station and the like. And finally, the first base station carries the measured service state of the first base station in a resource state report and sends the resource state report to the second base station.

S103: and the OSS receives the resource state report sent by the second base station.

Specifically, after receiving the resource status report sent by the first base station, the second base station forwards the resource status report to the OSS, so that the OSS can obtain the current service status of the first base station according to the content in the resource status report.

S104: and the OSS determines the service state of the first base station according to the resource state report.

In the prior art, when the OSS determines that the first base station is an unmanaged base station, the OSS often manually goes to a station or observes a service state of the unmanaged base station in a short distance, or observes the service state of the unmanaged base station through a core network device. However, the manual standing or close-range observation of the service state of the off-line base station is often limited by the spatial distribution distance of the base station, and has great physical environment constraints, and the time consumed for manually acquiring the service state of the off-line base station is too long; and the core network equipment is adopted to observe the service state of the unmanaged base station, and the base station in the LTE network belongs to one management system, and the core network belongs to the other management system, so that when the unmanaged base station exists, personnel of the base station management system still need to apply for the personnel of the core network management system to observe the operation state of the unmanaged base station, so that manual application, approval, coordination and the like are needed in the middle, and the service state of the unmanaged base station still cannot be obtained in time. Therefore, no matter which mode in the prior art is adopted, the OSS cannot acquire the current service state of the first base station within the first time, which greatly affects the reliability of the LTE network; however, in the embodiment of the present invention, once the OSS determines that the first base station is an unmanaged base station, the OSS sends a start control command to the second base station to enable the second base station to initiate a resource status query procedure to the first base station, and further, obtains the service status of the first base station through the second base station, without human participation or being limited by a physical environment or a spatial distribution distance of the base station.

In the method for detecting a service state of a base station provided in the embodiment of the present invention, when the OSS determines that the first base station is disconnected from the OSS in communication, the OSS sends, to the second base station, a start control command for instructing the second base station to send a first resource state request message to the first base station, so that the second base station initiates a resource state query procedure to the first base station and obtains a resource state report of the first base station, and thus the OSS may receive the resource state report sent by the second base station and determine the service state of the first base station according to the resource state report. The method of the embodiment of the invention does not need human participation and is not limited by physical environment or spatial distribution distance of the base station, so that the OSS can timely and effectively acquire the service state of the first base station when the first base station is taken off line, thereby ensuring stable operation and maintenance of the mobile communication network.

Fig. 5 is a flowchart illustrating a second method for detecting a service state of a base station according to an embodiment of the present invention. The embodiment relates to a specific process of sending a stop control command to a second base station after an OSS learns a service state of an off-line base station, so that the second base station notifies a first base station to stop measuring the service state of the first base station. Further, on the basis of the above embodiment, after S104, as shown in fig. 5, the method includes:

s201: the OSS sends a stop control command to the second base station; wherein the stop control command is used for instructing the second base station to send a second resource status request message to the first base station; the second resource status request message includes a second registration request information element, where the second registration request information element is used to instruct the first base station to stop measuring the service status of the first base station.

Specifically, after the OSS learns the service status of the first base station, the OSS sends a stop control command to the second base station, where the stop control command is used to instruct the second base station to send a second resource status request message to the first base station. And after receiving the stop control command, the second base station sends a second resource state request message to the first base station, wherein the second resource state request message carries a second registration request cell. Optionally, the second RESOURCE STATUS REQUEST message may also be a RESOURCE STATUS REQUEST message in a protocol of 3GPP 36423, the second Registration REQUEST cell may also be a Registration REQUEST cell in the RESOURCE STATUS REQUEST message, and the Registration REQUEST cell takes the value of "stop" differently from the first Registration cell.

Optionally, the stop control command sent by the OSS to the second base station may be a message with any frame structure, or may be a control command with any format, and as long as the message or the control command sent by the OSS to the second base station has a function of "instructing the second base station to send the second resource status request message to the first base station", both the stop control command and the control command may be stop control commands.

Optionally, the stop control command sent by the OSS to the second base station may be sent periodically, that is, the OSS sends a start control command to the second base station periodically, and then the OSS sends the stop control command to the second base station periodically, that is, the OSS may obtain the service state of the first base station periodically, and certainly, stops obtaining the service state of the first base station periodically. This may reduce the signaling overhead of the OSS, the second base station and the first base station.

Further, the first resource status request message further includes at least one of an air interface load cell, an S1 transport load cell, and a hardware load cell. Optionally, the air interface load cell may be a flag bit in the first resource status request message, and when the value of the air interface load cell is 1, it indicates that the first base station is required to measure the air interface load condition of the first base station; optionally, the S1 transmission load cell may also be a flag bit in the first resource status request message, and when the value of the S1 transmission load cell is 1, it indicates that the first base station is required to measure the transmission load condition of the S1 port of the first base station; optionally, the hardware load cell may also be a flag bit in the first resource status request message, and when the value of the hardware load cell is 1, it indicates that the first base station is required to measure the hardware load of the first base station

Optionally, if the first resource status request message includes the first registration request cell, the resource status report may include the time-frequency resource usage rate of the first base station, that is, the resource status report indicates, to the OSS, the current time-frequency resource usage condition of the first base station.

Optionally, if the first resource status request message includes the air interface load cell, the resource status report may include the air interface load of the first base station, that is, the resource status report indicates, to the OSS, the current air interface usage of the first base station.

Optionally, if the first resource status request message includes the S1 transport load information element, the resource status report includes the S1 load of the first base station, that is, the resource status report indicates to OSS the current usage of the S1 port of the first base station.

If the first resource status request message includes the hardware load cell, the resource status report includes the hardware load of the first base station, that is, the resource status report indicates, to the OSS, the current usage of the hardware device of the first base station.

In the method for detecting a service state of a base station, when the OSS determines that the first base station is disconnected from the OSS, the OSS sends a start control command to the second base station, where the start control command is used to instruct the second base station to send a first resource state request message to the first base station, so that the second base station initiates a resource state query process to the first base station and obtains a resource state report of the first base station, and the OSS can receive the resource state report sent by the second base station, and determines a service state of the first base station according to the resource state report, without human involvement or limitation to a physical environment or a spatial distribution distance of the base station, so that the OSS can timely and effectively acquire the service state of the first base station when the first base station is disconnected from the service, and further can ensure stable operation and maintenance of a mobile communication network; in addition, the method provided in the embodiment of the present invention may further send a stop control command to the second base station to instruct the second base station to send a second resource status request message to the first base station after the OSS knows the service status of the unmanaged base station, so that the first base station stops measuring the service status of the first base station under the instruction of the second resource status request message, thereby reducing signaling overhead of the OSS, the second base station, and the first base station.

Fig. 6 is a flowchart illustrating a third method for detecting a service state of a base station according to an embodiment of the present invention. The embodiment relates to a specific process in which the second base station sends a first resource status request message to the first base station according to a start control command sent by the OSS to obtain a resource status report of the first base station, and reports the resource status report to the OSS. As shown in fig. 6, the method includes:

s301: the second base station receives a starting control command sent by the OSS; the start control command is sent by the OSS after detecting that the first base station is disconnected from the OSS, and the start control command is used to instruct the second base station to send a first resource status request message to the first base station.

When the OSS determines that the first base station is the offline base station, in order to timely acquire the service state of the first base station in a short time, the OSS sends a starting control command to the second base station, wherein the starting control command is used for indicating the second base station to send a first resource state request message to the first base station. Optionally, the start control command may be a message with any frame structure, or may be a control command with any format, and as long as the message or the control command sent by the OSS to the second base station has a function of "instructing the second base station to send the first resource status request message to the first base station," both may be referred to as a start control command.

S302: the second base station sends the first resource state request message to the first base station according to the starting control command; the first resource status request message includes a first registration request cell, where the first registration request cell is used to instruct the first base station to measure the service status of the first base station, and send the service status to the second base station in a resource status report.

Specifically, after receiving the start control command sent by the OSS, the second base station initiates a Resource status query procedure, that is, initiates a Resource status reporting Initiation procedure, to the first base station according to the indication of the start control command and a 3GPP 36423 protocol. The method specifically comprises the following steps: the second base station sends a first resource state request message to the first base station according to the indication of the starting control command, wherein the first resource state request message carries a first registration request cell, and the first registration request cell is used for indicating the first base station to measure the service state of the first base station. Optionally, the first RESOURCE STATUS REQUEST message may be a RESOURCE STATUS REQUEST message in a protocol of 3GPP 36423, and the first Registration REQUEST cell may be a Registration REQUEST cell in the RESOURCE STATUS REQUEST message, where the Registration REQUEST cell takes the value of "start".

S303: and the second base station receives the resource state report sent by the first base station.

Specifically, the second base station and the first base station can communicate normally because of the communication link between the second base station and the first base station. Therefore, the first base station may receive the first resource status request message sent by the second base station. After the first base station receives the first resource status request message sent by the second base station, the first base station measures its own service status according to the indication of the first registration request cell in the first resource status request message, for example: checking the service log of the first base station, measuring the current time frequency resource utilization rate of the first base station and the like. And finally, the first base station carries the measured service state of the first base station in a resource state report and sends the resource state report to the second base station.

S304: and the second base station sends the resource status report to the OSS, wherein the resource status report is used for indicating the OSS to determine the service state of the first base station according to the resource status report.

In the method for detecting a service state of a base station provided in the embodiment of the present invention, a start control command sent by an OSS and used to instruct the second base station to send a first resource state request message to a first base station is received by a second base station, and after the first resource state request message is sent to the first base station according to the start control command, a resource state report sent by the first base station is received and sent to the OSS, so that the OSS can determine the service state of the first base station according to the resource state report. The method of the embodiment of the invention does not need human participation and is not limited by physical environment or spatial distribution distance of the base station, so that the OSS can timely and effectively acquire the service state of the first base station when the first base station is taken off line, thereby ensuring stable operation and maintenance of the mobile communication network.

Fig. 7 is a flowchart illustrating a fourth embodiment of a method for detecting a service state of a base station according to the present invention. The embodiment relates to a specific process in which the second base station sends a second resource status request message to the first base station according to a stop control command sent by the OSS, so that the first base station stops measuring the service status of the first base station. Further, on the basis of the above embodiment, after S304, as shown in fig. 7, the method includes:

s401: the second base station receives a stop control command sent by the OSS; wherein the stop control command is used for instructing the second base station to send a second resource status request message to the first base station; the second resource status request message includes a second registration request information element, where the second registration request information element is used to instruct the first base station to stop measuring the service status of the first base station.

Specifically, after the OSS learns the service status of the first base station, the OSS sends a stop control command to the second base station, where the stop control command is used to instruct the second base station to send a second resource status request message to the first base station. And after receiving the stop control command sent by the OSS, the second base station sends a second resource state request message to the first base station, wherein the second resource state request message carries a second registration request cell. Optionally, the second RESOURCE STATUS REQUEST message may also be a RESOURCE STATUS REQUEST message in a protocol of 3GPP 36423, the second Registration REQUEST cell may also be a Registration REQUEST cell in the RESOURCE STATUS REQUEST message, and the Registration REQUEST cell takes the value of "stop" differently from the first Registration cell.

Optionally, the stop control command sent by the OSS to the second base station may be a message with any frame structure, or may be a control command with any format, and as long as the message or the control command sent by the OSS to the second base station has a function of "instructing the second base station to send the second resource status request message to the first base station," both of them may be referred to as a stop control command.

Optionally, the start control command may be periodically sent to the second base station by the OSS, and the OSS correspondingly periodically sends a stop control command to the second base station, that is, the OSS may periodically acquire the service state of the first base station, and certainly periodically stop acquiring the service state of the first base station. This may reduce the signaling overhead of the OSS, the second base station and the first base station.

Optionally, with continuing reference to fig. 7, further before the foregoing S303, the method may further include:

s501: the second base station receives a first resource state response message sent by the first base station, wherein the first resource state response message is used for indicating the second base station that the first base station starts the measurement of the service state of the first base station.

Optionally, the first RESOURCE status response message may be a RESOURCE status response message in a protocol of 3GPP 36423, which is used to indicate to the second base station that the first base station has currently initiated the measurement of the traffic status of the first base station.

In the method for detecting a service state of a base station provided in the embodiment of the present invention, a second base station receives a start control command sent by an OSS and used to instruct the second base station to send a first resource state request message to a first base station, and after sending the first resource state request message to the first base station according to the start control command, receives a resource state report sent by the first base station, and sends the resource state report to the OSS, so that the OSS can determine the service state of the first base station according to the resource state report. The method of the embodiment of the invention does not need human participation, and is not limited by physical environment or spatial distribution distance of the base station, so that the OSS can timely and effectively acquire the service state of the first base station when the first base station is taken off line, thereby ensuring stable operation and maintenance of the mobile communication network; in addition, the method provided in the embodiment of the present invention may further send a stop control command to the second base station to instruct the second base station to send a second resource status request message to the first base station after the OSS knows the service status of the unmanaged base station, so that the first base station stops measuring the service status of the first base station under the instruction of the second resource status request message, thereby reducing signaling overhead of the OSS, the second base station, and the first base station.
