Description

Mobile phone network interface communication tracking method

The invention relates to a communication tracking method for a mobile phone network interface, in particular to a measurement data acquired by using a mobile phone network interface, and converted into a database readable format and then imported into a database through a database. A method of distinguishing different user communication messages after query language processing.

Mobile phone network interface data can provide some very useful information, such as communication protocol causes or wireless product quality measurements, so it is of great help to eliminate network problems or optimize network parameter settings. However, when the communication tracking of the mobile phone network interface measurement data measured by the communication protocol analyzer is performed manually, since the tracking process is too cumbersome, it takes a lot of time to execute and is prone to error. If it is processed by the manufacturer's test equipment, in terms of real time, it is limited by the processing power of the device and the size of the buffer. When the amount of data is too large, data loss may occur. If it is handled in a non-instant manner, when the communication data of the mobile phone user is spanning two or more adjacent time measurement files, since the files are processed independently, the first file processing result will have data, and then There is no information in the file.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing the communication tracking method of the mobile phone network interface.

The object of the present invention is to provide a communication tracking method for a mobile phone network interface, which can process the measurement data of the mobile phone network interface across the file, so as to avoid incomplete communication program data, and can process all the data at a lower computer level. Non-instant data and no data loss problems, and the processing program is executed in the database query language, so it can provide better data processing speed. In addition, if the base station configuration data is required during the communication tracking process, it can be obtained through statistical analysis of the measurement data.

The communication tracking method of the mobile phone network interface that achieves the above object is to use the message data of the mobile phone network interface, and after the data is imported into the database, the communication processing of the different users can be distinguished through the database query language processing. The steps include: Step 1: Converting the communication protocol analyzer measurement data into a file readable file through the conversion unit, and storing the file in the database; Step 2: using the communication tracking engine to perform data table query on the database The data table association query dynamically generates the base station configuration data; in step 3, the communication tracking engine is used to perform data table query and data table association query on the data base to generate communication tracking parameters; and step 4: using the communication tracking engine to perform communication tracking on the database The parameter data table and the measurement data table are associated with the query to generate communication tracking data.

The invention provides a communication tracking method for a mobile phone network interface, in particular, a data packet captured by a mobile phone network interface, and a communication identification information is assigned after processing to distinguish communication messages of different calls.

This embodiment is described by the Iub interface communication tracking method of the UMTS (Universal Mobile Telecommunications System) mobile network. However, familiar with the art, the communication tracking method of other interfaces of the mobile phone network can be adjusted according to actual needs. It is limited to the embodiments.

Please refer to FIG. 1 , which is a system architecture diagram of a communication tracking method for a mobile phone network interface, which is applied to Iub interface communication tracking. In the system architecture, a communication protocol analyzer measurement data 11 is transmitted through the conversion unit 12 to convert the Iub interface measurement data into a readability file in a data table format. The information to be transferred (hereinafter also referred to as a field) must be set in the conversion unit 12, including the information required for the communication tracking process and the information to be observed, such as the cause of the communication protocol, the wireless measurement report of the mobile phone and the base station. Used to assist in the analysis of possible cause judgments of bad communication quality events, etc. The result of the conversion will convert the decoding of each message into a data column format. Then, the transfer result is imported into the database 13, and the imported data is referred to herein as the Iub data table, and the communication tracking engine 14 is used to perform Iub interface control message communication tracking on the data table, including: Node B application department (Node B Application Part, NBAP), access link control application protocol (ALCAP) and radio resource control (RRC) three communication protocol messages.

Referring to FIG. 2, a flow chart of the communication tracking method for the mobile phone network interface includes the following steps: Step 1: Adding the Iub data table to the base station identification (Site Id) and communication identification (Call) Id) Two fields, and use the communication protocol analyzer to connect the Iub interface's wiring number and the Asynchronous Transfer Mode (ATM) layer's Virtual Path Identifier (VPI) to distinguish the site to which each message belongs. Id and write the result to the Site Id field. The purpose of adding the Site Id field is because when there are more than one base station for the equivalent measurement, the data of different base stations must be processed separately when tracking the information of the Iub interface; Step 2: Statistical analysis Iub data table The data is obtained in a dynamic manner to obtain the configuration data of the base station. This data will be used to assist in generating the required communication tracking parameters. Referring to FIG. 3, the process diagram of the Path Id and the Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) corresponding data table is generated by the present invention, and the same base station ALCAP and RRC communication protocol are counted. The message information, wherein the Channel Id (CID) assigned by the Establish Request message 31 is equal to the CID used to transmit the RRC Connection Setup Complete message 32. The most frequently associated result is the Path Id and VPI of the base station. VCI corresponding data table (VPI, VCI and CID are all ATM link identification); Step 3: 23, obtain communication tracking parameters of all radio links (Radio link) of each call. The so-called wireless link refers to the connection established between the mobile phone and the base station. The mobile phone may establish different wireless links with different base stations during the entire communication. The communication tracking parameter is obtained according to the message flow defined by the mobile communication specification. Referring to the processing sequence diagram of the communication tracking parameter generated by the present invention shown in FIG. 4, the RRC Connection Request message 41 of the RRC communication protocol and its user equipment are first queried. Identifying the (UE Id) field and assigning a unique Call Id value, then using the UE Id to associate with the RRC Connection Setup message 42 of the RRC communication protocol, obtaining the UL SC, and then using the UL Link and the NBAP communication protocol. The Setup Request message 43 is associated, ..., and so on, and all communication tracking parameters are available, including Call Id, filter parameter values for each protocol, and start and end times for each protocol filter. The purpose of the communication start and end time parameters is to prevent the communication tracking parameters from being filtered due to reuse reasons, and to filter out many unnecessary messages. In addition, the data query processing time can be greatly reduced; if the mobile or wireless coverage overlap factor, the mobile phone will Perform a soft handover procedure. At this time, the same call will establish different wireless links simultaneously or sequentially with different base stations. These different wireless links will have the same value of communication tracking parameters. Processing, the Call Id parameter value of the different wireless links of the same call will be the same; Step 4: For the wireless link whose communication tracking parameter is incomplete, that is, the measurement time has ended but the call has not been completed, The relevant information will be saved as a new data sheet and moved to the next new quantity measurement file at the next time to continue processing. In this way, even if the call spans several files, it can be tracked; in step 525, the Iub data table and the communication tracking parameter data table are associated with the query, and the Call Id value of the query result is written into the Call Id field to Differentiate the communication message of different calls; for the wireless link with incomplete communication tracking parameters, the communication program displayed by the communication tracking result will also be incomplete. However, if the identification of Call Id is used, the processing result of the file will have the same Call Id. The value of the data means that they are on the same call.

Although the above steps are used for the measurement of time-adjacent and different files, it is also applicable to the same file. Due to the processing rate consideration, the file is divided into several smaller files.
