Description

Calibration comprehensive test method and device for terminal

Technical Field

The invention relates to the field of terminal testing, in particular to a comprehensive testing and calibrating method and device for a terminal.

Background

Long Term Evolution (LTE) is one of the mainstream technologies in the Evolution process from the third Generation mobile communication technology (3G, 3rd-Generation mobile communication technology) to the fourth Generation mobile communication technology (4G), and is increasingly supported in the communication field, and gradually draws high attention in the global scope, thereby having a wide application prospect.

For a User Equipment (UE), due to the difference of the radio frequency devices on the UE, the radio frequency devices of the UE need to be calibrated before the UE leaves the factory, and appropriate compensation measures are taken to eliminate the difference. In addition, it is necessary to detect the compensation measures for the UE through comprehensive measurement to determine whether each index of the UE meets the index requirement of the 3GPP (3 generation Partnership Project) protocol.

The calibration of the UE radio frequency device needs to complete the calibration of the uplink transmitted power control word and the downlink received gain control word. Currently, a UE calibration scheme generally sends a message to the UE through calibration software (running on a PC side) to notify the UE to enter an uplink normal mode, and then continuously sends an uplink power control word to the UE through the calibration software to complete calibration of the uplink power control word; then the calibration software sends a message to the UE to inform the UE to enter a downlink normal receiving mode, and then the calibration software continuously changes the cell power and continuously requests downlink gain information from the UE to finish the calibration of the downlink receiving gain control word. In addition, after calibration of a certain frequency BAND (BAND) is completed, calibration software is required to send a message to the UE to change to another frequency BAND for uplink and downlink calibration. The common calibration mode requires frequent message interaction between the calibration software and the UE terminal, and since the calibration software runs on the PC side and the physical layer software executing the calibration command runs on the UE terminal side, the message interaction between the two is time-consuming, so that when the UE terminal is produced in batch on the production line, more time is required to be consumed, and the productivity is seriously affected. In addition, the existing calibrated comprehensive test scheme uses a signaling interaction mode, and requires multiple signaling interactions between the UE and the comprehensive tester to establish a Radio Resource Control (RRC) link, and then performs various index tests required by the 3GPP protocol.

Example 1

The embodiment of the invention provides a calibration comprehensive test method of a terminal, which is applied to one side of a calibration device, and as shown in fig. 1, the processing flow of the method comprises the following steps:

step 101, sending a meter side calibration pattern sequence to a test meter.

And the instrument side calibration pattern sequence is used for testing the instrument to obtain uplink power information.

In this embodiment, when a calibration device in which calibration software is located performs terminal calibration, a calibration pattern sequence is first constructed, where the calibration pattern sequence specifies a calibration frequency band to be calibrated, a set of uplink power control words and downlink gain control words to be calibrated for one calibration frequency band, timing information of changes of the uplink power control words and the downlink gain control words during calibration, and timing information of switching of each calibration frequency band.

After the calibration pattern sequence is constructed by the calibration device, the instrument side calibration pattern sequence required by the test instrument in the calibration process can be sent to the test instrument. The meter side calibration pattern sequence comprises calibration frequency bands, a group of downlink gain control words corresponding to each calibration frequency band, timing information of downlink gain control word change in the calibration process of each calibration frequency band, and timing information of switching of each calibration frequency band.

And 102, sending a calibration mode entering notification message to the UE, wherein the calibration mode entering notification message carries a UE side calibration pattern sequence corresponding to the instrument side calibration pattern sequence.

Meanwhile, the calibration device may send a calibration mode entering notification message to the UE, where the calibration mode entering notification message carries a UE-side calibration pattern sequence corresponding to the instrument-side calibration pattern sequence, which is required by the UE in the calibration process. And the UE side calibration pattern sequence is used for the UE to acquire downlink gain information.

The UE side calibration pattern sequence comprises the calibration frequency bands, a group of uplink power control words corresponding to each calibration frequency band, timing information changed by the uplink power control words in the calibration process of each calibration frequency band, and timing information switched by each calibration frequency band.

The UE-side calibration pattern sequence and the meter-side calibration pattern sequence include the same calibration frequency band and the same timing information for switching between calibration frequency bands.

Step 103, receiving the initial cell synchronization completion message fed back by the UE, and sending a message for starting a fast calibration process to the UE.

After receiving the UE side calibration pattern sequence, the UE searches out an initial cell corresponding to a first calibration frequency band according to the first calibration frequency band in the UE side calibration pattern sequence, starts an initial cell synchronization process, and feeds back an initial cell synchronization completion message to the calibration device after the initial cell synchronization is completed; and after receiving the initial cell synchronization completion message fed back by the UE, the calibration device sends a message for starting a rapid calibration process to the UE.

And step 104, receiving the uplink power information of the calibration frequency band sent by the test instrument and the downlink gain information of the calibration frequency band sent by the UE, and processing to obtain the uplink power information corresponding to the uplink power control word and the downlink gain information corresponding to the downlink gain control word.

After receiving the message for starting the rapid calibration process, the UE calls an uplink software and hardware module of the UE terminal to send a PUSCH signal according to a group of uplink power control words corresponding to a first calibration frequency band in the UE side calibration pattern sequence information, autonomously completes the change of the group of uplink power control words corresponding to each calibration frequency band and the switching of the calibration frequency band according to the timing information of the change of the uplink power control words in the calibration process of each calibration frequency band and the timing information of the switching of each calibration frequency band, and sends a PUSCH signal in an uplink subframe; and receiving PDSCH signals sent by the test instrument in a downlink subframe, and detecting the PDSCH signals to obtain downlink gain information of each calibration frequency band.

After receiving the PUSCH signal sent by the UE, the test instrument learns that the rapid calibration process is started; therefore, timing synchronization among the calibration device, the UE and the test instrument is completed; the test instrument starts to autonomously complete the change of a group of downlink gain control words corresponding to each calibration frequency band and the switching of the calibration frequency band according to the timing information of the change of the downlink gain control words in the calibration process of each calibration frequency band and the timing information of the switching of each calibration frequency band, and sends PDSCH signals in downlink subframes; and receiving a PUSCH signal sent by the UE at an uplink subframe, and detecting the PUSCH signal to obtain uplink power information of each calibration frequency band.

After acquiring the uplink power information and the downlink gain information of each calibration frequency band, the calibration device sorts the calibration results of the uplink power control words and the downlink gain control words to obtain the uplink power information corresponding to the uplink power control words and the downlink gain information corresponding to the downlink gain control words so as to form a calibration code table corresponding to the UE, and writes the calibration code table into a FLASH memory (FLASH) of the UE for the UE to use in non-signaling and signaling processes.

An embodiment of the present invention provides a terminal calibration method, which is applied to a UE side, and as shown in fig. 2, a processing flow of the method of the present embodiment includes the following steps:

step 201, receiving a calibration mode entering notification message sent by a calibration device, where the calibration mode entering notification message carries a UE side calibration pattern sequence.

And step 204, sending the downlink gain information of each calibration frequency band to the calibration device.

An embodiment of the present invention provides a terminal calibration method, which is applied to one side of a test instrument, as shown in fig. 3, a processing flow of the method of the present embodiment includes the following steps:

step 301, receiving a meter side calibration pattern sequence sent by the calibration device.

The meter side calibration pattern sequence comprises calibration frequency bands, a group of downlink gain control words corresponding to each calibration frequency band, timing information of downlink gain control word change in the calibration process of each calibration frequency band, and timing information of switching of each calibration frequency band.

Step 302, after detecting the PUSCH signal sent by the UE, starting to autonomously complete the change of a set of downlink gain control words corresponding to each calibration frequency band and the switching of the calibration frequency band according to the timing information of the change of the downlink gain control words in the calibration process of each calibration frequency band and the timing information of the switching of each calibration frequency band, and sending a PDSCH signal in a downlink subframe; and receiving a PUSCH signal sent by the UE in an uplink subframe, and detecting the PUSCH signal to obtain uplink power information of each calibration frequency band.

Step 303, sending the uplink power information of each calibration frequency band to the calibration apparatus.

In the fast calibration process of the method of this embodiment, only a limited number of message interactions exist among the calibration device, the UE and the test instrument, and switching the calibration frequency band and changing the uplink power control word and the downlink gain control word are both performed by the UE and the test instrument according to the information in the respective calibration pattern sequences, so that the UE and the test instrument need to maintain strict timing unification, otherwise, the timing abnormality occurs to cause uplink and downlink abnormality, and finally, the calibration fails.

In the method of this embodiment, after receiving an initial cell synchronization completion message fed back by the UE, the calibration apparatus sends a message for starting a fast calibration process to the UE; after receiving the message for starting the rapid calibration process, the UE calls an uplink software and hardware module of the UE terminal to send a PUSCH signal according to a group of uplink power control words corresponding to a first calibration frequency band in the UE side calibration pattern sequence information, and the test instrument learns that the rapid calibration process is started after receiving the PUSCH signal sent by the UE; therefore, timing synchronization among the calibration device, the UE and the test instrument is completed.

After the calibration device, the UE and the test instrument complete timing synchronization, the three do not need to carry out any message interaction during the whole uplink and downlink calibration period. And the UE terminal and the instrument respectively change the uplink power control word and the downlink gain control word according to the timing information specified by the calibration pattern sequence, and after the calibration of a group of uplink power control words and a group of downlink gain control words of one calibration frequency band is completed, the UE terminal and the instrument are respectively and autonomously switched to the next calibration frequency band to start the calibration of a new calibration frequency band. Therefore, the number of message interaction among the calibration device, the UE and the test instrument can be greatly reduced, and the calibration efficiency is improved.

In addition, according to the uplink and downlink subframe proportioning format on the LTE protocol, in the uplink subframe, the UE receives a PUSCH signal sent by the UE according to a PUSCH signal sent by an uplink power control word, the test instrument detects the PUSCH signal to obtain uplink power information of each calibration frequency band, and the calibration of the uplink power control word is completed; in a downlink subframe, a test instrument receives a PDSCH signal sent by the test instrument according to uplink and downlink gain control words, UE (user equipment) receives the PDSCH signal sent by the test instrument, detects the PDSCH signal to obtain downlink gain information of each calibration frequency band, and finishes calibration of the downlink gain control words; therefore, the aim of simultaneous uplink and downlink calibration is fulfilled, and the calibration time is shortened.

Example 2

An embodiment of the present invention provides a terminal calibration method, and as shown in fig. 4, a processing flow of the method of the present embodiment includes the following steps:

step 401, the calibration device sends a meter side calibration pattern sequence to the test meter.

Step 402, the calibration device sends a notification message of entering the calibration mode to the UE, where the notification message of entering the calibration mode carries a UE-side calibration pattern sequence corresponding to the instrument-side calibration pattern sequence.

Meanwhile, the calibration apparatus may send a notification message of entering a calibration mode to the UE, where the notification message of entering the calibration mode carries a UE-side calibration pattern sequence required by the UE in the calibration process. The UE side calibration pattern sequence comprises the calibration frequency bands, a group of uplink power control words corresponding to each calibration frequency band, timing information changed by the uplink power control words in the calibration process of each calibration frequency band, and timing information switched by each calibration frequency band. Optionally, the calibration apparatus further includes timing information for storing the downlink gain information.

The UE-side calibration pattern sequence and the meter-side calibration pattern sequence include the same calibration frequency band and the same timing information for switching between calibration frequency bands. Since there are few downlink gain control elements in a normal situation, the timing information for switching each calibration frequency band may be a time for each calibration frequency band to complete calibration of a set of uplink power control words corresponding to the calibration frequency band. Assuming that the calibration frequency BAND is BAND38, the corresponding set of uplink power control words is 10, 11, and 12, and the timing information of the uplink power control word change is changed once in 5ms, the timing information of the calibration frequency BAND38 switch is 15ms before switching to the next frequency BAND.

Step 403, after receiving the notification message of entering the calibration mode, the UE starts an initial cell synchronization process according to the first calibration frequency band in the UE-side calibration pattern sequence, and feeds back an initial cell synchronization completion message to the calibration apparatus after the initial cell synchronization is completed.

After receiving the notification message of entering the calibration mode, the UE searches for an initial cell corresponding to a first calibration frequency band according to the first calibration frequency band in the UE side calibration pattern sequence in the message, starts an initial cell synchronization process, and after the initial cell synchronization is completed, the UE feeds back an initial cell synchronization completion message to the calibration apparatus.

Step 404, after receiving the initial cell synchronization completion message fed back by the UE, the calibration apparatus sends a message for starting a fast calibration procedure to the UE.

And after receiving the initial cell synchronization completion message fed back by the UE, the calibration device sends a message for starting a rapid calibration process to the UE until the UE is ready to start calibration.

Step 405, after receiving the message for starting the fast calibration process, the UE sends a PUSCH signal in an uplink subframe according to the UE side calibration pattern sequence; and receiving PDSCH signals sent by the test instrument in a downlink subframe, and detecting the PDSCH signals to obtain downlink gain information of each calibration frequency band.

After receiving the message for starting the rapid calibration process, the UE autonomously completes the change of a group of uplink power control words corresponding to each calibration frequency band and the switching of the calibration frequency band according to the timing information of the change of the uplink power control words in the calibration process of each calibration frequency band and the timing information of the switching of each calibration frequency band, and sends PUSCH signals in uplink subframes; and receiving PDSCH signals sent by the test instrument in a downlink subframe, and detecting the PDSCH signals to obtain downlink gain information of each calibration frequency band.

Step 406, after detecting the PUSCH signal sent by the UE, the test instrument starts sending a PDSCH signal in a downlink subframe according to the instrument side calibration pattern sequence; and receiving a PUSCH signal sent by the UE in an uplink subframe, and detecting the PUSCH signal to obtain uplink power information of each calibration frequency band.

After detecting the PUSCH signal sent by the UE, the test instrument starts to autonomously complete the change of a group of downlink gain control words corresponding to each calibration frequency band and the switching of the calibration frequency band according to the timing information of the change of the downlink gain control words in the calibration process of each calibration frequency band and the timing information of the switching of each calibration frequency band, and sends a PDSCH signal in a downlink subframe; and receiving a PUSCH signal sent by the UE in an uplink subframe, and detecting the PUSCH signal to obtain uplink power information of each calibration frequency band.

Step 407, reading the uplink power information of the calibration frequency band detected by the test instrument and the downlink gain information of the calibration frequency band detected by the UE, and processing to obtain the uplink power information corresponding to the uplink power control word and the downlink gain information corresponding to the downlink gain control word.

The calibration device may send an uplink power information request message to the test instrument, and the test instrument feeds back the detected uplink power information of the calibration frequency band to the calibration instrument; meanwhile, the calibration device may also send a downlink gain information request message to the UE, and the UE feeds back the detected downlink gain information of the calibration frequency band to the calibration instrument.

Of course, after the calibration of the UE and the test instrument is completed, the uplink power information and the downlink gain information may be actively fed back to the calibration device.

After acquiring the uplink power information and the downlink gain information of each calibration frequency band, the calibration device sorts the calibration results of the uplink power control words and the downlink gain control words to obtain the uplink power information corresponding to the uplink power control words and the downlink gain information corresponding to the downlink gain control words so as to form a calibration code table corresponding to the UE, and writes the calibration code table into the FLASH of the UE for the UE to use in the non-signaling and signaling processes.

After the calibration of the upper and lower control words is completed, the terminal needs to be comprehensively tested, as shown in fig. 5, the comprehensive testing process provided by the method of this embodiment includes the following steps:

and step 408, the calibration device sends an integrated test environment setting notification message to the test instrument, wherein the integrated test environment setting notification message includes the test frequency band and the uplink and downlink parameter information.

And 409, the test instrument sets the comprehensive test environment of the test frequency band, and feeds back a setting completion message to the calibration device after the comprehensive test environment is set.

Step 410, the calibration device receives the setting completion message and sends a notification message of the integrated test mode to the UE, where the notification message of the integrated test mode carries the test frequency band.

Step 411, the UE receives the notification message of the integrated test mode, starts synchronization of the initial test cell according to the test frequency band, and feeds back a synchronization completion message of the initial test cell to the calibration apparatus after completing synchronization of the initial test cell.

After receiving the notification message of entering the integrated test mode, the UE searches out an initial test cell corresponding to the test frequency band according to the test frequency band in the message, starts the synchronization process of the initial test cell, and feeds back an initial test cell synchronization completion message to the calibration device after the synchronization of the initial test cell is completed.

Step 412, after receiving the initial test cell synchronization completion message, the calibration device sends a message for starting a non-signaling integrated test flow to the UE, where the message for starting the non-signaling integrated test flow includes information of uplink and downlink parameters.

Step 413, the UE sends a PUSCH signal in the uplink subframe according to the uplink and downlink parameter information, receives a PDSCH signal in the downlink subframe, decodes the PDSCH signal to obtain downlink index information, and sends the downlink index information to the calibration apparatus.

Decoding the PDSCH signal to obtain downlink index information comprises the following steps: BLock Error Rate (BLER) information, and the like.

And 414, after receiving the PUSCH signal, the test instrument sends the PDSCH signal in the downlink subframe according to the uplink and downlink parameter information, receives the PUSCH signal in the uplink subframe, decodes the PUSCH signal to obtain uplink index information, and sends the uplink index information to the calibration device.

The uplink index information obtained by decoding the PUSCH signal comprises: error Vector Magnitude (EVM), Adjacent Channel Leakage Ratio (ACLR), power, residual frequency offset, and the like.

After the calibration device obtains the uplink index information and the downlink index information of the test frequency band, whether the index information meets each index required by the 3GPP protocol or not is judged, and if the index information meets each index required by the 3GPP protocol, the test of the test frequency band is passed; if not, the test frequency band test is failed. After completing the uplink and downlink index test of a test frequency point, the calibration device sends messages to the test instrument and the UE respectively so as to switch to a new test frequency band and perform the uplink and downlink index test of the new test frequency band.

Step 408 and 414 are non-signaling comprehensive testing steps, which are implemented by adopting a software piling mode, providing a drive function interface by uplink and downlink software and hardware modules of the UE, sending PUSCH signals in uplink subframes according to test frequency bands specified by the calibration device and information of uplink and downlink parameter information, i.e., downlink gain control words, uplink power control words, RB number, modulation mode, etc., in uplink subframes according to uplink and downlink subframe proportioning formats specified by the LTE protocol, and decoding PDSCH signals in downlink subframes to obtain information of downlink index information, i.e., BLER information, etc.; meanwhile, the test instrument sends PDSCH signals according to the test frequency band specified by the calibration device and the information of uplink and downlink parameter information, namely downlink gain control words, uplink power control words, RB number, modulation mode and the like, in a downlink subframe, and decodes PUSCH signals in an uplink subframe to obtain uplink index information. Therefore, a signaling interaction process for establishing RRC connection which is complicated and time-consuming can be avoided, and the comprehensive testing efficiency is improved; meanwhile, expensive test instrument signaling plug-ins are not required to be purchased, and cost is reduced.

In actual measurement, the method of the embodiment completes calibration and comprehensive measurement comparison of seven frequency BANDs including BAND38, BAND39, BAND40 and BAND41 of TDD-LTE and BAND1, BAND3 and BAND7 of FDD-LTE, the existing calibration and comprehensive measurement method needs more than four minutes, and the method of the embodiment completes calibration and comprehensive measurement of all seven frequency BANDs only needs one minute, so that the calibration and comprehensive measurement time is greatly saved, the calibration and comprehensive measurement efficiency is improved, and further the productivity is improved.
