Description

Terminal comprehensive measurement method and device, computer storage medium

Technical field

The present invention relates to the field of terminal testing, and in particular, to a method and device for comprehensively measuring calibration of a terminal, and a computer storage medium.

Background technique

Long Term Evolution (LTE) is one of the mainstream technologies in the evolution of the third generation mobile communication technology (3G) to the fourth generation mobile communication technology (4G, the 4th Generation). The communication field has received more and more support, and has gradually gained high attention on a global scale and has broad application prospects.

For User Equipment (UE), due to the difference in the RF device itself on the UE, the RF device needs 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 test the compensation measures of the UE through the comprehensive test to determine whether the UE's indicators meet the requirements of the 3GPP (3GPP) Partnership Agreement.

Calibration of the UE radio device requires calibration of the power control word for the uplink transmission and the gain control word for the downlink reception. At present, the UE calibration scheme generally sends a message to the UE through the calibration software (running on the PC side) to inform the UE to enter the uplink normal transmission mode, and then continuously sends the uplink power control word to the UE through the calibration software to complete the calibration of the uplink transmission power control word. Then, the calibration software sends a message to the UE to inform the UE to enter the downlink normal receiving mode, and then continuously adjusts the cell power through the calibration software and continuously obtains the downlink gain information from the UE to complete the downlink receiving gain control word calibration. In addition, after the calibration of a certain frequency band (BAND) is completed, the calibration software is also required to send a message to the UE to change to another frequency band for uplink and downlink calibration. This general calibration method requires The calibration software frequently performs message interaction with the UE terminal, and since the calibration software runs on the PC side, and the physical layer software that executes the calibration command runs on the UE terminal side, the message interaction between the two is time consuming, so that the production line is on the production line. When mass production of the UE terminal is performed, it takes a lot of time and seriously affects the production capacity. In addition, the existing calibrated comprehensive test solution uses signaling interaction, which requires multiple signaling interactions between the UE and the comprehensive tester to establish a Radio Resource Control (RRC) link, and then the 3GPP protocol. The required indicators are tested. This type of signaling comprehensive measurement requires the purchase of expensive instrumentation signaling plug-ins on the one hand, and time-consuming and impact on capacity on the other hand.

The group uplink power control word is changed and the calibration frequency band is switched, and the PUSCH signal is sent in the uplink subframe; and the PDSCH signal sent by the test instrument is received in the downlink subframe, and the PDSCH signal is detected to obtain the downlink gain signal of each calibration frequency band. interest.

Step 406: After detecting the PUSCH signal sent by the UE, the test instrument starts to transmit the PDSCH signal in the downlink subframe according to the meter side calibration pattern sequence, and receives the PUSCH signal sent by the UE in the uplink subframe, and detects the PUSCH. The signal obtains uplink power information for each calibration band.

After detecting the PUSCH signal sent by the UE, the test instrument starts to automatically complete the calibration frequency band according to the timing information of the downlink power control word change and the timing information of the calibration frequency band switching in each calibration frequency band calibration process. The switching of the set of downlink power control words and the switching of the calibration frequency band, the PDSCH signal is sent in the downlink subframe; the PUSCH signal sent by the UE is received in the uplink subframe, and the PUSCH signal is detected to obtain the uplink power information of each calibration frequency band.

In addition, the UE and the test instrument according to the uplink-downlink subframe matching format on the LTE protocol, in the uplink subframe, the UE transmits the PUSCH signal according to the uplink power control word, and the test instrument receives the PUSCH signal sent by the UE, and detects the PUSCH signal. The uplink power information of each calibration frequency band completes the calibration of the uplink power control word; in the downlink subframe, the test instrument receives the PDSCH signal transmitted by the uplink and downlink gain control words, and the UE receives the PDSCH signal sent by the test instrument, and detects the PDSCH signal to obtain each The downlink gain information of the calibration frequency band is completed, and the calibration of the downlink gain control word is completed; thus, the purpose of simultaneous calibration of the uplink and the downlink is achieved, and the calibration time is shortened.

Of course, the UE and the test instrument may actively feed back the uplink power information and the downlink gain information to the calibration apparatus after the calibration is completed.

After obtaining the uplink power information and the downlink gain information of each calibration frequency band, the calibration device sorts the uplink power control word and the downlink gain control word calibration result, and obtains uplink power information corresponding to the uplink power control word and the downlink gain control.

Step 410: The calibration apparatus receives the setup complete message, and sends a comprehensive test mode notification message to the UE, where the test mode notification message carries the test frequency band.

Step 411: The UE receives the comprehensive test mode notification message, and starts initial test cell synchronization according to the test frequency band. After completing the initial test cell synchronization, the initial test cell synchronization complete message is fed back to the calibration device.

After receiving the notification mode notification message, the UE searches for the initial test cell corresponding to the test frequency band according to the test frequency band in the message, and starts the initial test cell synchronization process. After the initial test cell synchronization is completed, the UE The UE feeds back to the calibration device an initial test cell synchronization complete message.

Step 412: After receiving the initial test cell synchronization complete message, the calibration device sends a message to start the non-signaling test process to the UE, where the message for starting the non-signaling test process includes the uplink and downlink parameter information.

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

After obtaining the uplink indicator information and the downlink indicator information of the test frequency band, the calibration apparatus determines whether the indicator information meets various indicators required by the 3GPP protocol, and if yes, the test frequency band test passes; if not, the test frequency band test Did not pass. After completing the test of the uplink and downlink indicators of a test frequency point, the calibration device will separately send a message to the test instrument and the UE to switch to a new test frequency band and perform the uplink and downlink index test of the new test frequency band.

Steps 408-414 are non-signaling test steps, which are in the form of software piling, and the drive function interface is provided by the uplink and downlink software and hardware modules of the UE, and is configured in the uplink subframe according to the uplink and downlink subframe matching format specified by the LTE protocol. The test frequency band specified by the calibration device, and the uplink and downlink parameter information, that is, the downlink gain control word, the uplink power control word, the RB number, the modulation mode, and the like, transmit the PUSCH signal, and the PDSCH signal is decoded in the downlink subframe to obtain the downlink indicator information, that is, the BLER information. At the same time, the test instrument transmits the PDSCH signal in the downlink sub-frame according to the test frequency band specified by the calibration device, and the uplink and downlink parameter information, that is, the downlink gain control word, the uplink power control word, the RB number, the modulation mode, and the like, and is in the uplink subframe. The PUSCH signal is decoded to obtain uplink indicator information. In this way, the complicated and time-consuming signaling interaction process for establishing an RRC connection can be avoided, and the comprehensive measurement efficiency can be improved; and the high test instrument signaling plug-in is not required to be purchased, thereby reducing the cost.

In the actual measurement method, in the actual measurement, the BAND1, BAND39, BAND40, BAND41 and FDD-LTE BAND1, BAND3, BAND7 of TDD-LTE are completed in seven calibrations and comprehensive measurement comparison, the existing calibration and comprehensive measurement methods It takes more than four minutes, and the calibration and comprehensive measurement of all seven frequency bands by the method of the present embodiment only takes one minute, which greatly saves the calibration comprehensive measurement time, improves the efficiency of the calibration comprehensive measurement, and further increases the productivity.
