Description
Technical Field
The invention belongs to the technical field of tracking test, and particularly relates to a method, a system, a storage medium and equipment for tracking test of a multimode mobile terminal.
Background
At present, testing is an indispensable link in the whole period of mobile terminal baseband software development, and the testing mode directly influences the software development efficiency and quality. One important test mode is trace debugging, which can monitor system variables, memory, state machines, function execution conditions or task scheduling conditions and the like by inserting trace points into software in advance, packaging trace information and outputting trace information. In order to facilitate the developer to locate the problem according to the tracking information, the WINDOWS platform side needs to set up a device for tracking test, receive decoding and display the tracking content. Because of the particularity of the mobile terminal, especially in the network access test process, the output speed of the tracking information is quite high, so that the tracking test device is required to have enough capability of processing the tracking information, the speed of decoding and displaying the tracking information is increased, and the tracking information is ensured not to be lost. Besides real-time tracking, the tracking test device also needs to provide a function of playing back tracking files for a base band software developer to locate problems.
The drive test is to test the whole course along a specific route in an area by means of test software, test mobile phones, test vehicles and other tools, simulate the terminal user to feel the network service quality, and evaluate the call quality by obtaining wireless environment parameters, call connection conditions and testers. The method provides necessary network coverage, call quality information and the like for departments such as planning, engineering, operation and maintenance of the network, and provides references for network optimization and subsequent establishment.
A 4G multimode (multi mode) mobile communication terminal supporting GSM (Global System for Mobile communication, global system for mobile communications), UMTS (Universal Mobile Telecommunication System, universal mobile telecommunications system) and LTE (Long Term Evolution ) simultaneously.
Through the above analysis, the problems and defects existing in the prior art are as follows: the existing tracking test method is easy to lose tracking information, meanwhile, the speed of testing and processing the tracking information is low, and meanwhile, the development period of new requirements of a test system is long.
The difficulty of solving the problems and the defects is as follows: once the development tester determines the computer for tracking test, the computing processing and storage capacity of the computer are limited, but the tracking test system can shorten the reading and writing time of the tracking message file and improve the speed of decoding and displaying the tracking message. The read-write time of the trace message file is shortened mainly by a memory mapping read-write mode. Although the read-write speed of the large file is greatly improved compared with that of the traditional hard disk by adopting a memory mapping mode, the time is still required to be occupied, so that the tracking test system in the invention adopts a double-memory mapping mode, the memory mapping file 1 is used for receiving tracking data, when the received data file is larger than the preset size, the data is copied to the memory mapping file 2, and the memory mapping file 2 writes the disk according to the preset tracking file size, so that the aim is to ensure that one tracking message is not missed. The speed of decoding positioning tracking information is improved through a specific array recording method. The fast check point bit message includes: and the storage address quick-speed query point message of a certain tracking message is obtained by calculating the memory base address obtained based on the ID (ID, record number) in the specific array and the memory offset by utilizing the characteristic of quick traversal query speed of the array data structure storage. The device is found to consume the most computer resources and take the longest time after a large number of tests, so when the tracking message is decoded by receiving data, only the content information in the tracking message is decoded and displayed in all message display main windows. Such as layer 3 message, only layer 3 signaling names are displayed, and no specific content is displayed. When a developer needs to analyze a certain important trace message, all contents of the trace message are decoded again, and detailed contents and values of each field are displayed in a tree structure. The message display module distributes the message to different sub-windows according to the tracking type in the tracking message data, but whether the sub-windows are displayed or not is controlled by the external configuration file of the device, so that a test developer can control the display of the different windows by modifying the related parameters in the external configuration file of the device. The purpose is to improve the decoding display speed of the device.
The meaning of solving the problems and the defects is as follows: the method ensures that one trace message is not missed, any trace message provides information for the analysis problem of development testers, particularly key trace messages, if one trace message is missed, misjudgment is caused, and the analysis and positioning problem of the development testers is seriously influenced. The system decodes and displays the tracking information, and improves the efficiency of analyzing and solving the problems by development and testing personnel. Especially in the real-time tracking test process, a tester needs to initiate a service, such as a call, a data downloading service and the like, after a certain specific tracking message, so that it is more important to improve the speed of decoding and displaying the tracking message.
The invention has high expansion performance, and can realize other related functions only by the fact that the two parties are about the tracking frame header information for the mobile terminals working in different modes to output the tracking information.

The technical effects of the present invention will be further described with reference to specific examples.
Example 1:
The multimode mobile terminal has very high output speed of tracking information in the real-time tracking test process, so the device adopts the memory file mapping technology to process the disk writing of the tracking file; when the stored tracking file is played back, the file is read in the mode, so that the speed of decoding, displaying and inquiring the tracking information is increased. Compared with the traditional read/write file read-write mode, the speed is improved by 5-6 times.
The memory mapping refers to that the positions of files on a hard disk are in one-to-one correspondence with areas with the same size as a block in a process logic address space, and when one piece of data in a memory is to be accessed, the memory mapping is converted into one piece of data of the accessed file. This correspondence is purely a logical concept and physically nonexistent, since the logical address space of the process itself is nonexistent. The purpose of this approach is to reduce the copying of data between user space and kernel space, which is suitable for large data processing. When the memory mapping file is used for processing the file stored on the disk, I/O operation on the file is not needed, which means that the file is not needed to be applied and the buffer memory is not needed to be allocated when the file is processed, all file buffer memory operations are directly managed by the system, and the steps of loading file data into a memory, writing back the data from the memory to the file, releasing memory blocks and the like are eliminated, so that the efficiency of processing the file with large data volume by using the memory mapping file is very high.
The memory mapping procedure is as shown in fig. 2:
step 1: establishing memory mapping and returning a pointer pointing to a process logic address;
Step 2: converting the logical address to a physical address by an MMU (Memory Management Unit );
Step 3: the MMU fails because the MMU cannot find the physical address corresponding to ptr in the address mapping table, a page fault interrupt is generated, a corresponding page is found in the swap by the interrupt response function, and if the corresponding page cannot be found, the file is read from the hard disk into the physical memory through the relation established by the memory mapping;
Step 4: and finishing virtual memory replacement. If the physical memory is found to be insufficient when copying the data, the temporarily unused physical pages are exchanged to the hard disk through a virtual memory mechanism (swap);
The tracking information received by the device is identified by adopting a unique record number (ID) mode and is stored in an array in a specific data structure, so that other modules in the device can conveniently and quickly locate the tracking information. The specific data structure comprises various parts of the tracking message frame structure, such as a TAG mark and a frame number, and also adds information which is convenient for the tracking device to position, including a memory offset, a record number and the like;
The specific mode of the positioning tracking message is as follows: the memory base address obtained from 2 is added with the memory offset obtained from 2 to calculate the storage address of a certain trace message. As shown in fig. 3.
In the real-time tracking process, a mode of polling the CPU of the computer is adopted by the message receiving module, the message decoding module and the message distributing and displaying module, and the message receiving module and the message decoding module are ensured to have higher priority than other modules.
The message decoding module only analyzes the frame header data of the tracking message in the decoding process, does not decode the frame content part of the tracking message, ensures that the message receiving module has enough CPU time slices to receive the data, improves the decoding speed and prevents the tracking message from being lost.
The device has high expansion performance, and for the mobile terminals working in different modes to output tracking information, other related functions can be realized only by the two parties about the tracking frame header information.
The message display module distributes the trace types in the trace message data to different window displays, decodes the content parts in the frames into visible character strings to display the visible character strings, tree-shaped display signaling structures and contents or displays statistical results in a drawing mode.
The message display module distributes the message to different sub-windows according to the tracking type in the tracking message data, but whether the sub-windows are displayed or not is controlled by an external configuration file of the device, so that a test developer can control the display of different windows by modifying relevant parameters in the configuration file. The purpose is to improve the decoding display speed of the device.
The message display module does not completely decode the content part of the message frame, especially the trace message with complicated structures such as layer three, EL1, measurement, etc., and only when a development tester needs detailed information for a certain trace message, the device rapidly locates trace data, decodes and displays the content part of the trace message in detail in a tree structure, and aims to improve the decoding display speed of the device.
The third layer is a baseband protocol stack software RRC layer signaling, and the coding format is ASN.1; IPC is signaling communicated between ARM microprocessor and DSP processor in hardware architecture of baseband chip; the measurement is signaling of the mobile communication terminal for measurement in the wireless mobile environment;
the apparatus supports complete air interface information display and decoding. And supporting to open a plurality of message windows simultaneously, and realizing simultaneous display of different types of signaling and decoding thereof. The locking and searching function of the signaling is supported, the filtering and displaying of the decoding signaling is supported, and the rapid positioning of the user on the signaling flow layer is facilitated.
Example 2:
As shown in FIG. 1, the device runs on the WINDOWS platform side and mainly comprises a tracking message receiving module, a tracking message decoding module, a tracking message display module, a tracking message query module, a tracking message decoding and deriving module and a tracking message playback module, wherein the functions of the modules are as follows:

2) A trace message decoding module: the frames are decoded according to the trace message frame format agreed by both parties, and the decoded content is put into the specific array described in method 6. And simultaneously notifying the tracking message display module to display the message content.

The invention adopts a simulation test method in the development stage, and the specific simulation test mode is as follows: the method comprises the steps of inserting a DB9 serial port adapter connector into a serial port interface of a host computer, welding two pins of TXD and RXD read-write data of the serial port adapter connector together, enabling a local serial port to automatically receive data, constructing tracking frame data which are already agreed by a tracking module on the embedded platform side through software of the device during development and self-receiving, and checking whether the device meets various requirements. The method can be simultaneously developed with the embedded platform side tracking module, and shortens the development period.
And the simulation test is completed, so that the test under the real environment can be performed, namely, the drive test performed under the real mobile network environment by using the multimode mobile terminal is performed. As the simulation test is passed, the device has basically stable functions when being provided for users, and only needs to be noted that the discharge speed of the tracking data in the real environment is much faster than that in the simulation test, so that the stage focuses on whether the decoding display speed of the device meets the requirement or not and whether the tracking frame is lost or not.
In addition, the switching between the simulation test and the real use can be performed by modifying parameters through configuration files outside the device, and the code is not required to be modified.
In addition to testing the hardware (including CPU, memory, hard disk configuration, etc.) configuration of the host, the window decoding display speed related factors of the present device also include:
1. The window refreshing selects whether to refresh line by line or page by page (2000 pieces of tracking data per page), and the decoding display speed of page by page refreshing is far higher than that of line by line refreshing;
2. whether other sub-windows are displayed or not is except the main window for displaying all the messages, only the main window is displayed for displaying all the messages, and the other sub-windows are closed and the displaying speed is the fastest;
3. The main window of all message display displays the content of the tracking frame, whether all the content in the frame is displayed or partially displayed, and the data of the display frame is minimum and the speed is faster;
The following test result data are all from the test under the real network environment, and the device only displays all the main windows of the messages when in the test, closes other sub-windows, and displays all the contents in the frame structure of fig. 6. The test PC host is configured as i5-7500 x643.41G Hz dual-core, 8G memory processor, and can refresh up to 2743 trace message displays per second per page, and refresh up to 771 trace message displays per second per row. And the received tracking data decodes the sn number in the frame header continuously, and the tracking loss-free condition is indicated.
