[0034] The network element, the method for uploading an MR message, and the method for generating a performance index file provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0035] According to the requirements of the existing measurement report technical specifications, the current measurement report collection granularity is required to be between 2s and 12s, and the MR server supports a maximum capacity of 30,000 carriers. According to this configuration, it can be calculated that the message reception volume of the MR server is 38000/ s, the existing scheme adopts the UDP protocol in the process of message reception, and the message belongs to the unconfirmed message transmission mode, so in the poor network environment, or in the process of memory sorting of the MR server (performance problem), there will be packet loss, which will eventually lead to MR. Messages are lost and the accuracy of the generated MR northbound files is skewed. Therefore, a more stable MR message collection solution is required to solve the problem of loss of measurement report messages due to various reasons.
[0036] An embodiment of the present invention provides a method for a network element to upload an MR message, such as figure 1 shown, including:
[0037] Step 101, receiving the measurement report MR message and the call detail record CDL message reported by the terminal and the base station;
[0038] Step 102, the received MR messages are formed into MR files independently;
[0039] When the terminal and the base station report the MR message to the network element, they will also report the CDL message to the network element. A large number of MR messages and CDLs are mixed together. In this embodiment of the present invention, when the MR message and the CDL message are received, the MR message is separately composed MR file, so as to realize the separation of MR message and CDL message. Since MR message adopts file mode, multiple MR messages need to be formed into MR file, and UDP data packet encapsulation is not required.
[0040] Step 103: When it is determined that the MR interface link between the network element and the MR server is normal, the MR file is reported to the MR server by using the file transfer protocol FTP mode, so that the MR server can use the file transfer protocol FTP mode to report the MR server according to the MR in the MR file. Messages generate performance metrics files.
[0041] The network element that receives the reported MR message, such as the MR server in the network management, is usually connected to multiple lower-level network elements. In the embodiment of the present invention, the MR message is separately formed into an MR file in the lower-level network element, so as to realize the separation of the MR message and the CDL message, and reduce the This reduces the performance pressure of the MR server for parsing files, improves the processing capability of the MR server, and is conducive to the high integration of network management products; the embodiment of the present invention uses FTP to transmit MR files. Since FTP is a confirmation message transmission mode, that is, when the transmission is successful, the It will feed back a successful reception message, otherwise it will feedback a reception failure message. Therefore, this method ensures that there is no packet loss problem in the MR message, which effectively guarantees the correctness of the performance index files obtained by the network optimization platform and the northbound network management, and effectively ensures the analysis and optimization of the network optimization platform. The correctness of the results ensures that the northbound network management can effectively manage and monitor the lower-level network management.
[0042] Preferably, the network element that uploads the MR message in this embodiment is the RNC, and specifically uploads the MR message to the MR server in the network management OMRC.
[0043] Preferably, in this embodiment, the separated MR messages are formed into MR files, which specifically include:
[0044] Every set time interval, for example, every 5 minutes, the received MR messages are separately composed into MR files; or when the information amount of the received MR messages that are not composed of MR files reaches the set threshold, such as when it reaches 20M, no MR files will be composed. The MR messages make up the MR file.
[0045] like figure 2As shown, the network element in this embodiment includes a signaling board and a global board, and specifically, the HSPS (High Signal Process Subsystem, high-speed signaling subsystem) on the signaling board sends the MR message and CDL message reported by the terminal to the OAMS (Operation And Maintenance Subsystem), OAMS separates CDL messages and MR messages and sends them to the global board. Specifically, it can be sent to the global board when the size reaches a certain size, such as 12k, or it can be sent to the global board at a certain interval. For example, if it is sent to the global board at an interval of 5s, the global board composes the received MR messages into an MR file. Specifically, the global board receives MR messages and composes an MR file according to 20M or 5 minutes. Further preferably, in this embodiment, the global board compresses the MR file, and uploads the compressed MR to the MR server through FTP. When sending through FTP, it can be determined whether the other party receives it successfully according to the feedback of the receiver.
[0046] like figure 2 As shown, the RNC will detect the MR interface link with the MR server. Preferably, in this implementation, when it is determined that the MR interface link between the network element and the MR server is abnormal, it waits until it is detected that the network element is connected to the MR server. When the MR interface link between the MR servers is normal, the MR file and the file transfer protocol FTP are reported to the MR server. In this embodiment, the MR interface link detection is performed, and specifically, it is detected whether the interface between the global board in the RNC and the network maintenance module and the interface between the network maintenance module and the MR server are normal.
[0047] Preferably, in this embodiment, when it is determined that the MR file is successfully transmitted, the MR file that has been successfully transmitted is deleted; when it is determined that the MR file has not been successfully transmitted, the MR file that has not been successfully transmitted is stored, such as on the global board, Set the transmission interval for retransmission at the interval; and delete the MR file with the earliest storage time by setting the update time at the interval. For example, the oldest MR file is automatically deleted every 3 days.
[0048] In order to realize the correct deletion of the MR file, preferably, the MR file naming rule in this embodiment includes sequentially: MRrnc, which identifies that the file is from the RNC; network element identifier, which identifies which RNC the file specifically comes from; and the file creation date. Preferably, in the following form:
[0049] MRrnc_<4-character NE ID (hexadecimal)>_<8-character file creation date (year, month, day)>_<4-character file creation time (hour, minute)>.dat.
[0050] The file creation date uses the local time, year-month-day (YYYYMMDD) format.
[0051] The file creation time is in local time, hour and minute (HHMM) format.
[0052] The embodiment of the present invention also provides a method for generating a performance indicator file, such as image 3 shown, including:
[0053] Step 301, receiving the MR file reported by the network element using the file transfer protocol FTP method;
[0054] Because of the FTP method, the result of whether the reception is successful will be fed back to the sender.
[0055] Step 302, analysing the MR file to obtain an MR message;
[0056] The MR file reported in the embodiment of the present invention only includes MR messages, so the MR server directly parses the MR file to obtain a performance index file, which improves the processing efficiency of the MR server.
[0057] Step 303, according to the requirements of the northbound network management and/or network optimization platform, parse the MR file to obtain a performance index file, and report the obtained performance index file to the northbound network management and/or network optimization platform.
[0058] In this embodiment, the MR message is parsed according to the performance indicators required by the northbound network management and/or the network optimization platform to obtain the performance indicators required by the northbound network management and/or the network optimization platform, and these performance indicators are converted into the xml file format. and performance index values are uploaded to the FTP server or network optimization platform in the northbound network management system. The FTP server in the northbound NMS collects xml files every time, and parses the performance index values in the xml files into the database.
[0059] In this embodiment, the upper-level network element receiving the MR message does not need to separate the MR message from the CDL message, which reduces the performance pressure of the MR server for parsing files, improves the processing capability of the MR server, and facilitates high integration of network management products.
[0060] In this embodiment, the upper-level network element that receives the MR message is the MR server in the network management OMCR. If the MR server fails and the status of the MR server is abnormal, no MR file is processed at this time; after the failure is recovered, the MR interface returns to normal, and the RNC re-uploads MR file during MR failure, the MR server starts the normal MR file processing flow. The JAVA process of the MR server will perform memory sorting after a certain amount of memory is used, and will not receive or process any messages during this time. However, because the FTP mode is adopted and the above processing mechanism is adopted at the RNC side, the MR message will not be lost.
[0061] When the MR server parses the received MR file, if the MR file is a compressed file, it first decompresses the compressed MR file.
[0062] Preferably, the MR is parsed to obtain the file type of the performance indicator file, which specifically includes binary type and plaintext type, that is, the original file type and the sample file type, and the performance indicator file is named in the file type, sending performance indicator file. The NE ID of the NE and the creation time of the performance index file. Preferably, it can take the following form:
[0063] TD-SCDMA_ _ _<2-character NE ID (in hexadecimal, indicating which OMCR the file comes from)>_<14-character File creation time (year, month, day, hour, minute, second) )>.xml.
[0064] The file creation date uses the local time, year-month-day-hour-minute-second (YYYYMMDDHHMMSS) format.
[0065] For example, the network element RNC ID is 68, and the MRO and MRS files generated at 23:30:00 on November 25, 2011 are named as follows:
[0066] TD-SCDMA_MRS_DATANG_OMCR_44_20111125233000.xml
[0067] TD-SCDMA_MRO_DATANG_OMCR_44_20111125233000.xml
[0068] like figure 2 As shown, the principle of control and message transmission of MR files among RNC, OMCR, northbound network management, and network optimization platform is given.
[0069] In addition to the MR server, the OMRC also includes a network element adaptation module. The network element adaptation module is connected to the network maintenance module in the RNC through the management interface. The network element adaptation module completes the MR task management functions through the management interface, such as task creation and measurement content. Customize, modify, etc.
[0070] This embodiment of the present invention provides a reporting method for MR messages. In practice, CDL messages are also reported to OMRC. Preferably, in this embodiment, after separating MR messages and CDL messages, the RNC separates the separated CDL messages. A CDL file is formed and reported to OMRC by FTP.
[0071] Based on the same inventive concept, the embodiment of the present invention also provides a network element for uploading MR messages and a network element for generating performance index files. The methods of the indicator files are similar, so the implementation of these devices can refer to the implementation of the method, and the repetition will not be repeated.

The MR messages in generate performance metrics files.
[0076] Preferably, the file generating unit 402 is specifically configured to compose the received MR messages into an MR file every set time interval; or when the information amount of the MR messages that do not constitute an MR file reaches a preset threshold, compose an MR message that does not constitute an MR file. The MR messages of the file make up the MR file.
