Description

A NodeB cell-level fault location analysis method

technical field

The invention relates to a method for analyzing NodeB faults in the wireless field, in particular to a method for locating and analyzing NodeB cell, public channel, public measurement and cell information update faults by using log records.

Background technique

WCDMA system is an open system. The system mainly includes CN (core network), UTRAN (universal terrestrial radio access network) and UE (terminal equipment). Among them, NodeB belongs to the UTRAN part, and one of its main functions is the establishment and release of radio bearers, including logical cell management (establishment, reconfiguration, deletion), common transport channel management (establishment, reconfiguration, deletion), radio link management (creation, reconfiguration, deletion), public measurement management (creation, deletion, reporting), etc.

After the UE is turned on, it firstly synchronizes with a serving cell with the strongest signal through the cell search process; then receives the broadcast information of the cell and performs a location update process. When the UE is called, the UE needs to query its own paging information through the PCH (Paging Channel) to complete the paging process; the WCDMA system will also send data to the UE user through the FACH (Forward Access Channel). If the information of the cell changes, the UE under the cell needs to be notified through a system message update. If the cell supports HSDPA, the HSDPA channel is established through reconfiguration of the physical shared channel; the RNC (radio network controller) also obtains the communication quality through the establishment of public measurement, and timely adjusts the NodeB to improve the call quality and call capacity.

It can be seen that the existence of cells, public channels, cell information updates, and public measurement management is the prerequisite for the entire WCDMA system to implement services. According to the 25.433 protocol, after the WCDMA system is started, the RNC will send the cell information through the NBAP (Node B Application Part) protocol. Management (establishment, reconfiguration, deletion), public channel management (establishment, reconfiguration, deletion), physical shared channel reconfiguration, system message update, measurement management (establishment, deletion, failure, report) and other messages to NodeB, in order to Manage cell, public measurement, public channel and cell information update.

However, in practical applications, from time to time, we encounter abnormalities in cells, public channels, public measurements, or cell information updates. In the daily maintenance of existing networks, the following methods are usually used to analyze faults:

1. Performance statistics function: performance statistics is to measure the quality of the current network by counting key statistical items in the network. This method is to count the success/failure times of the signaling process in a specific measurement period, and feed back the statistical value to The network management system conducts a comprehensive analysis by the network management system, and guides the expansion of the existing network and problem solving through the analysis results.

Performance statistics is a long-term, or a statistical function of periodic tasks. It counts the success rate or failure rate of the signaling process within a period of time. The statistical results themselves are very rough, and this function is statistical history. Data, and abnormal analysis cannot be performed on the cause of signaling failure.

Two, the whole network signaling detection method: the method of signaling tracking is to track the call process in the standard protocol interface (such as Iu, Gb, Gr) by the signaling tracking instrument, especially from the standard protocol messages in different network elements, and These related messages are sent to the network management center, and the captured messages are analyzed, and the network is optimized according to the analysis results, and some problems are solved at the same time.

The whole network tracking method is a kind of real-time tracking, which needs to be tracked by special third-party instruments on all interfaces. This kind of tracking will generate a large amount of data. The current 2G whole network signaling tracking only tracks part of the network. For the 3G system, these tracking messages will be massive, especially if it is necessary to track the messages of the access network. How to obtain useful information from a large number of message traces will be a very large workload. In addition, tracing through signaling also requires a lot of experience to be able to quickly discover problems in messages, and this method is not easy to popularize among maintenance personnel.

3. Alarm: The processing and analysis of alarm information by the network management system can eliminate and manage network faults. When the system fails, the alarm system can send the cause of the alarm to the network management system in real time, and the network management system can analyze and eliminate the fault according to the cause of the alarm and the equipment.

Generally speaking, alarms focus on equipment failures, and less attention is paid to user failures. For example, when the user fails due to various reasons, such as attachment or PDP activation, it cannot be reflected in the alarm. Therefore, the alarm basically cannot reflect or solve the problem of locating an abnormal signaling of a single user.

To sum up, when the NodeB cell, common channel, public measurement and cell information update fail, there is no good way to locate and analyze the cause of the fault and then solve the fault in the process of locating the problem.

Contents of the invention

In view of the above problems, the purpose of the present invention is to provide a NodeB cell-level fault location and analysis method, so as to realize when a NodeB cell fault occurs, locate and analyze the cause of the fault, and further solve the fault.

Specifically, the present invention adopts a cell log record (CELLLOG), which can track problems in the cell, public channel, public measurement, and cell information update management process, and feed back to the network management system through standard protocol messages. The management system analyzes the problems in the cell according to these historical records, analyzes the problems through these message cells, and solves the faults through corresponding means.

Technical scheme of the present invention is as follows:

The NodeB receives the cell-related signaling message sent by the RNC;

The NodeB-side signaling processing module records the relevant signaling messages, and generates cell log standardized information;

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing;

The key point of the present invention is to introduce the cell log, and the cell log information includes cell log standardization information and cell environment status information. The NodeB signaling processing module generates cell log standardized information when processing cell-related signaling IUB messages, and records the information into the temporary memory buffer of NodeB; therefore, it can be interpreted to locate cell faults. After the interaction between RNC and NodeB (REQUEST and RESPONSE or REQUEST and FAILURE), the NodeB signaling processing module saves the information points of the relevant records into the temporary memory buffer of the NodeB to generate community log standardized information; specifically: in the memory The buffer dynamically allocates a continuous memory buffer indexed by the community ID, and the standardized information of the community log belonging to a community ID will be stored in the continuous memory, so that the data of the memory buffer to which the community ID belongs can be exported as needed; the community log When the standardized information is output, the signaling processing module at the NodeB side generates the cell environment status information at the same time, and the cell log standardization information and the cell environment status information are output together as the cell log information; the cell log information records the standard signaling process of the entire cell. When a failure occurs, the standardized information of the community logs in the temporary memory buffer can be interpreted to locate the cause of the failure. Since many base stations are distributed in remote areas and mountains, for convenience, the normalized information of the relevant community logs in the temporary memory buffer is generally first and community environment status information are output together as community log information to the memory or file where the system permanently saves the community log, and then the community log information is uploaded to the maintenance station by means of Ftp, and then the community log analysis tool can be used to analyze the log When fault location is performed, the standardized information of the community log is mainly analyzed, and the environmental status information of the community is referred to when necessary.

The community log standardized information structure standard is as follows:

In the CELLLOG message, the necessary information to report includes:

Cell Code: information point number. This mechanism determines the temporary memory storage address through the information point number, so the information point number needs to be unique in the entire log system;

Format String Information: Cell format string information. The information structure is the same as the parameter structure of printf in ANSI C, namely: char*Format[,argument].... format, which can flexibly record multiple key parameters according to the specific situation at the time, and display them in strings at the same time, which is more readable ;

CellIndex: cell index. The log standardization information of the same community index is stored in a continuous temporary memory. When the community management process is over, all the log standardization information under the same community index and the community environment status information are output to the memory or file where the system permanently saves the community log ;

Time: The system time for recording the log, the format is YYYY-MM-DD HH:MM:SS (year-month-day-hour-minute-second).

Refer to the following table for the structure standard of the community environment status information:

IE/Group Name Type and range Length(Bytes) Semantics description NodeB Information Information about NodeB >NcpID Integer 4 NCP number >NcpStatus Integer 4 NCP status >CpuLoad Integer 4 CPU usage IUB Msg Information Saved IUB port messages >Len Integer 4 message length >msgData[MAX_MSGLEN] Integer Array MAX_MSGLEN IUB news Procedure Information Information that needs to be recorded throughout the community management process >CellID Integer 4 cell number >LocalCellID Integer 4 local cell code >SccpchPhyChanId Integer 4 SCCPCH physical channel number >PchNum Integer 4 Number of PCHs >PrachPhyChanId Integer 4 PRACH physical channel number >AichPhyChanId Integer 4 AICH physical channel number >MeaId Integer 4 Measurement number >MeaType Integer 4 measurement type >Module1Information Information of external module 1 related to cell, public channel, public measurement, cell information update management IUB message processing module >>Module1AddrInformation Address information of external module 1 (uniquely determine an external module) >>>Module1CPUID Integer 4 CPU number of external module 1 >>>Module1DSPID Integer 4 DSP number of external module 1 >>>Module1PID Integer 4 Process number of outer module 1 >>Module1KeyInformation Key Information for Outer Module 1 >>>PSCH CircuitID Integer 4 Circuit number of PSCH >>>BCH FPID Integer 4 FP number of BCH ... … Module2 Information Information for Outer Module 2 ... …

Note the following four points in the above table:

1. The number of external modules refers to the number of external modules related to the cell, public channel, public measurement, and cell information update IUB message processing module. There are several external modules, and the environment status information structure of the cell has several external module information . Depending on the number of external modules, the number of external module information carried in the cell environment status information structure is also different, which can be expanded or deleted arbitrarily

2. The content of NodeB Information can be expanded or deleted arbitrarily, as long as it is NodeB information, and information that is helpful for cell, public channel, public measurement, and cell information update fault location can be placed under this content, such as: system message processing The size of the buffer, the number of messages currently saved, etc.

3. The content of Module(n) Addr Information can be expanded or deleted arbitrarily, as long as it is used to uniquely determine the information of the external module, it can be placed under this content, such as: the child process number of the external module, etc.

4. The content of Module(n) Key Information can be expanded or deleted arbitrarily, as long as it is the key information of an external module, it can be placed under this content.

Embodiment one

APP measurement initialization failure failure analysis:

The cell log records the standard signaling process of the entire cell, so faults can be located by analyzing the standard signaling process of the cell. Refer to Figure 1, Figure 1 shows the normal signaling process of APP public measurement initialization; if the APP public measurement initialization of a cell fails, first we upload the cell log with the maintenance station, and use the cell log analysis tool to analyze the cell log of the cell, the cell log is as follows :

It was found that NO.6 is the following community log:

COMMEA: (MEAID): The relative PRACH: (PRACHID) hasn't setup, so commonmeasurement init failed! \n

It can be seen from the translation that because the PRACH related to APP measurement has not been established, the initialization of APP public measurement fails.

Looking through the cell logs of the entire cell, it is found that after the cell is established, the PRACH is not established, and the measurement is directly established.

It is stipulated in the 433 protocol that if it is APP measurement initialization, it is necessary to establish a related PRACH, and if it is other public measurements, there is no such restriction.

The analysis shows that the measurement type is APP. If you are not at ease, you can use the iub message analysis tool (IUB message is an ASN1 standard coded message, note: ASN1 is the Abstract Syntax Notation One abstract syntax identifier. 1) to parse out the IUB message (ie public measurement initialization message), from which it can be seen that the measurement type is indeed APP.

In this way, we have full confidence in determining that the public measurement is the APP measurement, and the reason for its initialization failure is that the relevant PRACH (Physical Random Access Channel) has not been established.

It can be known from this embodiment that the cell log records all cell-related signaling interaction information between the NodeB and the RNC in the cell with the cell as an index, and complete IUB messages are stored in the cell environment state information. By analyzing the messages on the signaling plane, problems in the signaling process of the standard IUB interface can be quickly located.

Embodiment two

Common channel SCCPCH establishment failure failure analysis:

The cell log records the messages or function calls between NodeB internal modules, so even if an error occurs between internal modules, the fault can be located through the cell log.

Refer to Figure 2, Figure 2 shows the normal signaling process for SCCPCH public channel establishment; the establishment of SCCPCH public channel in a certain community fails, first we use the maintenance station to upload the community log, and use the community log analysis tool to analyze the community log of the community, the community log is as follows :

Analyzing the community log of this community, it is found that NO.7 has the following community log: SCCPCH (SCCPCHID): sccpch receive "Message of SCCPCH establishment failure of encoding module", error reason: "0xaa"

According to the error reason "0xaa" corresponding to the internal error index, it can be known that the SCCPCH establishment fails due to insufficient resources of the encoding module.

Therefore, even if an error occurs between internal modules, the cause of the fault can be quickly located through the cell log.
