Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a terminal throughput testing method and a terminal testing instrument.
Background
The terminal throughput is an important index for measuring the receiving performance of the terminal, and the LTE (Long Term Evolution ) terminal radio frequency conformance test protocol (36.521-1) gives the definition of the terminal throughput: the terminal throughput measurement is the effective information reception rate (in kbps) of a terminal obtained by dividing the number of information bits (in kb) successfully received by the terminal by the duration (in seconds) of a measurement period in one measurement period.
Because the terminal test instrument is an information sending end, the terminal test instrument cannot directly know the number of information bits successfully received by the terminal. In the prior art, after a terminal receives a Transport Block (TB) sent by a terminal test instrument, if a terminal HARQ (Hybrid Automatic Repeat reQuest) message is decoded successfully, the terminal feeds back an ACK (acknowledgement) message to the terminal test instrument, otherwise, feeds back a NACK (Negative acknowledgement) message. The terminal test instrument can know the bit number of the TB sent each time and can also know whether the TB sent each time is correctly received by the terminal through the ACK message and the NACK message, so the terminal test instrument can obtain the throughput of the terminal by recording the bit number of the TB sent each time and the ACK message or the NACK message corresponding to each TB. 36.521-1 requires that the test terminal throughput be greater than 95% of the peak throughput (i.e., maximum throughput). If the test terminal throughput is greater than 95% of the peak throughput, the terminal throughput passes the test, otherwise, the terminal throughput does not pass the test. The above terminal throughput test may be referred to as a decision criterion directly based on the throughput percentage.
In the prior art, a terminal test meter indirectly measures terminal throughput according to the following method: 36.521-1, a statistical decision method for mapping throughput to Error Rate (ER) is presented.
Firstly, when considering the terminal radio frequency consistency test, the TBs sent by the terminal test instrument are all sent by a fixed Reference Measurement Channel (RMC), and the TBs corresponding to each ACK message or NACK message are the same, so that the bit number of the TB sent by the terminal test instrument is proportional to the number of the ACK messages and the NACK messages.
Secondly, according to section G2.2 of 36.521-1, the amount of Time of the measurement period can be represented by the sum of the number of ACK message, NACK message and all DTX (Discontinuous Transmission) subframes in the measurement period, because each ACK message, NACK message and DTX subframe represents one Transmission TTI (Transmission Time Interval) and 1ms, and the number of them is actually the number of milliseconds of the measurement period. Wherein "all DTX subframes" includes two DTX subframes:
regDTX (fixed DTX) subframe: the channel is measured periodically according to the selected reference. In an actual network, this period of time indicates that the terminal is not being served and that other terminals are being served. In the TD-LTE mode, this time indicates that an uplink subframe and a special subframe are transmitted. The fixed DTX subframe configuration is different for different tests, but is not changed in one test. Such DTX is an uplink subframe in TDD or non-transmission determined by the network, and the terminal will not receive downlink data at this time.
statDTX (additional DTX) subframe: when the terminal should transmit an ACK message or a NACK message but does not transmit it, a statDTX subframe is generated. Since the statDTX subframe carries statistical randomness, it is also called a statistical DTX subframe. This occurs because the terminal does not expect to receive data or the received data is not data that the terminal expects. At this time, the terminal should receive the downlink data.
The Error Rate (ER) is a Ratio of the number of Error subframes (including NACK and statDTX) to the total number of subframes in a period of time, i.e., ER ═ NACK + statDTX)/(NACK + statDTX + ACK).
It can be seen that the test period can be understood as the time taken by the terminal test instrument to receive a certain number of ACK, NACK and statDTX subframes, the maximum throughput in one period is NACK + ACK + statDTX, and the actual throughput is ACK, so the relative throughput of a single test of any reference channel can be converted into an error rate. And for each measurement process using fixed RMC, ER can explicitly establish a mapping relation with throughput, so a statistical decision method for mapping throughput to Error Rate (ER) can replace the previous decision criterion directly using throughput percentage as an index.
The mapping relationship between ER and throughput is specifically established by the following formula:
relative throughput (ACK)/(NACK + ACK + statDTX) 1-ER
Therefore, the passing and failing of the terminal throughput can be performed by counting the following indexes: the number of NACKs, the number of ACKs, and the number of statDTX.
In consideration of the testing requirements of the terminal testing instrument, the total number of data blocks transmitted during the measurement period, namely the number of testblocks, needs to be counted, and the number of sub-frames to be tested, namely testsubframe num needs to be counted in order to control the testing time. Obviously, these criteria should comply with the following relationship:
TestBlock＝ACK+NACK+statDTX；
TestSubframeNum＝TestBlock+regDTX＝ACK+NACK+statDTX+regDTX。
in the prior art, a terminal test instrument starts to count the received NACK, ACK, and statDTX immediately after a counting switch is turned on. The statistical processing flow of the terminal test instrument for the statistics comprises the following steps: processing when the statistical switch configuration message is received and statistical processing of each statistic.
The processing flow when the statistical switch configuration message is received is shown in fig. 1, and will not be described in detail herein. The statistical processing flow of each statistic is shown in FIGS. 2-4, and will not be described in detail herein.
Therefore, in the prior art, the throughput test of the terminal is finally realized by adopting a mode that statistics of all statistics starts and ends simultaneously. However, in the operation of the actual LTE system, considering the realizability, the statistics are processed in the MAC layer, while scheduling and sending of the TB block in the MAC layer and corresponding feedback receiving have a certain timing relationship, and the processing in the MAC layer also has a time delay, and if the statistics of all the statistics start and end at the same time, a certain statistical error is inevitably caused.
Therefore, the prior art cannot solve the problem that the counting start and end intervals of all the statistics are actually not synchronous by adopting a mode that the statistics of all the statistics start and end at the same time, thereby causing statistical errors, and the prior art cannot be applied to a terminal test instrument which aims at counting with the statistical accuracy as a target.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
It should be noted that, in this document, "first" to "sixth" are used only to distinguish the same names, and do not imply a relationship or order between the names.
As shown in fig. 5, the present embodiment discloses a method for testing throughput of a terminal, which includes the following steps 501 to 503:
501. after a terminal throughput test is started, sending a test transmission block to the terminal, adjusting a first parameter value, and after a subframe interrupt message is received, adjusting a second parameter value and adjusting a third parameter value based on the subframe interrupt message; the first parameter value is used for indicating the number of test transport blocks (TestBlock) sent after the terminal throughput test is started; the second parameter value is used for indicating the number of test subframes TestSubframe after the terminal throughput test is started; the third parameter value is used to indicate the number of fixed discontinuous transmission subframes regDTX.
In this embodiment, the main execution body of the terminal throughput testing method is a terminal throughput testing instrument.
In this embodiment, the test Transport Block is a Transport Block (TB) sent by the terminal throughput test instrument after the terminal throughput test is started, that is, the TB sent to the terminal in the whole terminal throughput test process is called a test Transport Block.
In this embodiment, after the terminal throughput test is started, the first parameter value is adjusted each time a test transport block is sent to the terminal. For example, after the terminal throughput test is started, if 5 TBs are transmitted to the terminal and the initial value of the first parameter value is zero, the first parameter value is increased by 5. Of course, if the initial value of the first parameter value is set to the preset test number of the test transport blocks, the first parameter value is decreased by 5.
In this embodiment, the subframe interrupt message may be generated by the terminal throughput test meter itself or provided by an independent signal generator, and the subframe interrupt message is generated one every 1 ms.
In this embodiment, the second parameter value is adjusted each time the subframe interrupt message is received, that is, the number of test subframes TestSubframe is increased by 1 each time the subframe interrupt message is received.
In this embodiment, the adjusting the third parameter value based on the subframe interrupt message specifically includes: and if the current subframe corresponding to the subframe interruption message is an LTE TDD uplink subframe, adjusting a third parameter value, namely adding 1 to the regDTX number.
502. After a test transmission block is sent to the terminal and a feedback message corresponding to the test transmission block is received, adjusting a fourth parameter value, a fifth parameter value or a sixth parameter value; the fourth parameter value is used for indicating the number of the feedback messages as ACK confirmation messages; the fifth parameter value is used for indicating the number of the feedback messages as Negative Acknowledgement (NACK) messages; the sixth parameter value is used for indicating that the feedback message is the number of additional discontinuous transmission subframes statDTX;
in this embodiment, statistics on the feedback message does not start simultaneously with two statistics of the test transport block TestBlock and the test subframe TestSubframe, but starts after the test transport block is sent to the terminal and the feedback message corresponding to the test transport block is received.
503. And when the first parameter value reaches the preset total number of the TestBlock and the sum of the fourth parameter value, the fifth parameter value and the sixth parameter value reaches the preset total number of the TestBlock, obtaining the throughput of the terminal based on the first parameter value to the sixth parameter value, and testing the throughput of the terminal.
In this embodiment, for the case that the initial value of the first parameter value is the preset TestBlock total number, correspondingly, step 503 specifically includes: and when the first parameter value reaches zero and the sum of the fourth parameter value, the fifth parameter value and the sixth parameter value reaches the preset total number of TestBlock, obtaining the throughput of the terminal based on the first parameter value to the sixth parameter value, and realizing the test of the throughput of the terminal.
In this embodiment, because the number of the test transport blocks TestBlock, which is the first parameter value, reaches the preset total number of testblocks, and the sum of the fourth parameter value, the fifth parameter value and the sixth parameter value, which is the number of the feedback messages, reaches the preset total number of testblocks, the number of the test transport blocks samples is matched with the number of the feedback messages samples, and the feedback messages can accurately correspond to the test transport blocks, thereby ensuring the accuracy and integrity of the whole statistical process.
In this embodiment, after "obtaining the throughput of the terminal" in step 503, the terminal throughput may be tested based on the prior art to determine whether the test passes, which is not described in this embodiment again.
It can be seen that, for different statistics, the terminal throughput testing method provided in this embodiment starts statistics at different times, and compared with a manner in the prior art in which statistics for all statistics starts and ends simultaneously, the method respectively performs statistics for statistics with a timing relationship, that is, the number of testblocks, the number of testsubframes, and the number of regDTX are counted simultaneously, and the number of ACK messages, the number of NACK messages, and the number of stagdtx are counted after delay, thereby reducing statistical errors, overcoming the problem that the start and end intervals of statistics for each statistic are actual and asynchronous, and improving the accuracy of terminal throughput testing.
As shown in fig. 6, this embodiment discloses a method for testing throughput of a terminal, which is different from fig. 5 in that this embodiment provides a preferred implementation manner of step 502 "after sending a test transport block to the terminal and receiving a feedback message corresponding to the test transport block, adjusting a fourth parameter value, a fifth parameter value, or a sixth parameter value", and specifically includes the following steps 5021 to 5023:
5021. after sending a first test transport block to the terminal, adding an identifier to the process information of the hybrid automatic repeat request HARQ process associated with the first test transport block, where the identifier is used to indicate that the test transport block associated with the HARQ process is the first test transport block.
In this embodiment, in order to associate the statistics having the timing relationship, an identifier is added to the process information of the HARQ process associated with the first test transport block, so that the terminal throughput test instrument can determine whether the test transport block corresponding to the HARQ is the first test transport block in the terminal throughput test process by querying whether the process information of the HARQ process includes the identifier.
5022. And when receiving a feedback message sent by the terminal, checking the process information of the HARQ process associated with the feedback message, and after determining that the process information contains the identifier, adjusting a fourth parameter value, a fifth parameter value or a sixth parameter value based on the feedback message.
In this embodiment, when receiving a feedback message corresponding to a test transport block sent by a terminal, whether the feedback message is a feedback message corresponding to a first test transport block may be determined by checking whether process information of an HARQ process associated with the feedback message includes an identifier.
In this embodiment, after determining that the feedback message is the feedback message corresponding to the first test transport block, the number of ACK messages, the number of NACK messages, and the number of statDTX are counted, that is, the fourth parameter value, the fifth parameter value, or the sixth parameter value is adjusted based on the feedback message.
In this embodiment, the adjusting the fourth parameter value, the fifth parameter value, or the sixth parameter value based on the feedback message specifically includes:
if the feedback message is an ACK message, adjusting a fourth parameter value, namely adding 1 to the number of the ACK messages; if the feedback message is a NACK message, adjusting a fifth parameter value, namely adding 1 to the number of the NACK messages; if the feedback message is the additional discontinuous transmission subframe statDTX, adjusting a sixth parameter value, namely adding 1 to the number of the additional discontinuous transmission subframe statDTX.
5023. And after the fourth parameter value, the fifth parameter value or the sixth parameter value is adjusted based on the feedback message, the fourth parameter value, the fifth parameter value or the sixth parameter value is adjusted every time the feedback message sent by the terminal is received.
It can be seen that, in the method for testing throughput of a terminal disclosed in this embodiment, in consideration of a time delay relationship for obtaining different statistics, when measurement statistics starts, statistics start and end of different statistics are treated differently, and not all statistics starts at the same time, but the number of testblocks, the number of testsubframes, and the number of regDTX starts to be counted first, and the number of ACK messages, the number of NACK messages, and the number of statDTX starts to be counted after delaying, and performs association control by matching HARQ process information.
In a specific example, before step 501 "after starting the terminal throughput test and sending the test transport block to the terminal" in fig. 5 and 6, the method for testing the terminal throughput disclosed in this embodiment further includes step 500, not shown in fig. 5 and 6, of determining to start the terminal throughput test:
500. after receiving a statistical switch control message for a terminal throughput test, determining to start the terminal throughput test; and the statistical switch control message carries the information of the total number of the TestBlock sent after the terminal throughput test is started.
Correspondingly, in this embodiment, in step 503, "when the first parameter value reaches the preset TestBlock total number and the sum of the fourth parameter value, the fifth parameter value, and the sixth parameter value reaches the preset TestBlock total number, obtaining the throughput of the terminal based on the first parameter value to the sixth parameter value", specifically: and when the first parameter value reaches the total number of the testblocks indicated by the TestBlock total number information and the sum of the fourth parameter value, the fifth parameter value and the sixth parameter value reaches the total number of the testblocks indicated by the TestBlock total number information, obtaining the throughput of the terminal based on the first parameter value to the sixth parameter value.
The terminal throughput testing method disclosed in this embodiment starts a terminal throughput test after receiving a statistical switch control message for the terminal throughput test, and performs a terminal throughput calculation after a first parameter value, that is, the number of testblocks reaches the TestBlock total number indicated by the TestBlock total number information, and a sum of a fourth parameter value, a fifth parameter value, and a sixth parameter value, that is, the number of feedback messages reaches the TestBlock total number indicated by the TestBlock total number information, so that the number of test transport block samples matches the number of feedback message samples, and the feedback messages can accurately correspond to the test transport blocks, thereby ensuring the accuracy and integrity of the whole statistical process.
As shown in fig. 7, this embodiment discloses a method for testing throughput of a terminal, and this embodiment provides a preferred implementation manner of step 501 in fig. 5, after starting a terminal throughput test, sending a test transport block to the terminal, adjusting a first parameter value, and after receiving a subframe interrupt message, adjusting a second parameter value and adjusting a third parameter value based on the subframe interrupt message, and includes the following steps 5011 and 5012:
5011. after receiving a statistical switch control message for a terminal throughput test, simultaneously starting a first statistical switch, a second statistical switch and a third statistical switch; the starting of the first statistic switch is used for indicating the start of counting the number of test transport blocks (TestBlock) sent in the terminal throughput test process; the opening of the second statistical switch is used for indicating the number of test subframes in the process of starting to count the terminal throughput; and the opening of the third statistical switch is used for indicating the start of statistics of the number of the regDTX of the fixed discontinuous transmission subframes.
In this embodiment, different statistical switches are added for different statistics, and the opening of the statistical switch is used to indicate the start of statistics.
5012. And after the first statistical switch, the second statistical switch and the third statistical switch are started, sending a test transmission block to the terminal, adjusting a first parameter value, and after a subframe interrupt message is received, adjusting a second parameter value and adjusting a third parameter value based on the subframe interrupt message.
In this embodiment, after receiving the statistical switch control message for the terminal throughput test, the first statistical switch, the second statistical switch, and the third statistical switch are simultaneously turned on, thereby realizing statistics of the TestBlock number, the TestSubframe number, and the regDTX number.

Based on the terminal throughput testing method disclosed in this embodiment, this embodiment further provides a terminal throughput testing state machine, as shown in fig. 8, which is specifically described as follows:
INIT: an initial state. At this time, the measurement item is not started yet, and the system is in a natural operation state.
PRE: a ready state. And the external part sends the resource configuration required by the measurement, and the system completes the state after the resource configuration.
RUN: and (4) operating state. And according to the resource allocation required by the measurement item, continuously operating scheduling and data transmission feedback receiving, but not performing measurement and index statistics.
PRE _ MEAS: the measurement ready state. The external/user requests to start the measurement and the system receives a measurement initiation configuration message. At this point the TestBlock and TestSubframe statistics switches are turned on to begin counting both statistics.
START _ MEAS: the start state of the measurement. After the scheduling resource allocation module completes the allocation of the TB resources, if the current measurement state is found to be the PRE _ MEAS state, the position of the feedback statistical mark in the HARQ process information corresponding to the currently scheduled TB is valid.
WAIT _ MEASRPT: and waiting for the reporting state of the measurement result. When the feedback information processing module receives the feedback, if the current measurement state is found to be START _ MEAS and the feedback statistical flag bit is valid in the HARQ process information of the TB block corresponding to the current feedback information, the feedback information (ACK/NACK/stat dtx) statistical switch is turned on at this time, and the feedback information STARTs to be counted. While the measurement state is advanced to WAIT _ MEASRPT.
Based on the terminal throughput testing state machine, the flow of the terminal throughput testing method is described as follows:
the system is in an INIT state after initial start, and the measurement state is modified into a PRE state after receiving a configuration downlink transmission format message issued by an external master control system. And when receiving a message for starting downlink scheduling issued by the main control system, starting downlink scheduling and TB transmission according to a previously configured downlink data transmission format, and modifying the measurement state into an RUN state.
In the RUN state, after the control message receiving module receives a message for starting the throughput measurement item sent by the master control system, the testBlock and TestSubframe counting switches are turned on, the running system counts the two indexes, and the measurement state is modified into the PRE _ MEAS state.
And when the time control module receives the interruption of one subframe header, if the TestSubframe statistical switch is on, the TestSubframe statistical quantity is accumulated, otherwise, the statistical treatment is not carried out. If the current is a TDD system, the regDTX is also counted according to the uplink and downlink conditions of the current subframe.
And checking the current measurement state after the scheduling resource allocation module finishes the resource allocation of one TB, if the current measurement state is the PRE _ MEAS state and indicates that the measurement process is started, setting the position of a feedback statistical sign in the HARQ process information corresponding to the currently scheduled TB to be valid, and modifying the measurement state into the START _ MEAS state. Otherwise, the position of the feedback statistical mark in the HARQ process information is invalid. Before TB transmission, if a TestBlock statistic switch is on, the TestBlock statistic is accumulated, otherwise, the statistic processing is not performed.
When the feedback information receiving module receives feedback information (ACK/NACK/statDTX), it first queries the current measurement state and HARQ process information corresponding to the current feedback information. If the current measurement state is a START _ MEAS state and the position of the feedback statistical flag in the corresponding HARQ process information is valid, it indicates that the TB corresponding to the current feedback information is the first TestBlock at the beginning of measurement, the feedback information is the feedback corresponding to the first TestBlock at the beginning of measurement, statistics of feedback needs to be started, at this time, a feedback information (ACK/NACK/statDTX) statistical switch is turned on, and the measurement state is modified to WAIT _ MEASRPT. And then, the feedback information receiving module counts the condition of the switch according to the feedback information, if the statistical switch is opened, the corresponding statistic of ACK/NACK/statDTX is accumulated, otherwise, the statistic processing is not carried out.
And when the statistic TestBlock is the statistical TestBlock number required by measurement, closing the TestBlock and TestSubframe statistical switches to stop the subsequent statistics of the two indexes.
And when the feedback statistic ACK + NACK + statDTX is the number of the statistical testBlock required by the measurement, closing the feedback information statistical switch to stop the subsequent statistics of the index. And then, calculating indexes such as ER, throughput and the like according to the protocol by using each statistical index, and reporting. And after the report is finished, the measurement state is restored to the RUN state, and a measurement statistical process is finished.
