FIELD OF TECHNOLOGY

The present invention relates to the field of communications and, in particular, to a method and apparatus for checking signals, as well as to a computer storage medium.

BACKGROUND OF THE INVENTION

Currently, with the rapid development of mobile terminals, it is imperative to improve the performance of the mobile terminal. Checking the radio frequency indicators of the mobile terminal is a must.

In the existing method for checking the radio frequency indicators of the mobile terminal between the terminal and the network side, it is usually necessary to create a signal line, and then ascending and descending indicators are checked. Nevertheless, in the method described above, the measured indicators are radio frequency indicators for a certain period after the communication line between the terminal and the network is created, and in many radio frequency variants the signal indicators cannot be measured. It is not possible to track the characteristics at each time point over the entire life of the signal as they track the signal of the main frequency band using an oscilloscope. Moreover, the gaining popularity of the Long Term Evolution (LTE) standard has led to the emergence of many LTE radio frequency indicators. Checking only the main indicators of the radio frequency in one frequency range takes half an hour. Test time increases as the number of frequency ranges increases. Signals in LTE have a more complex frequency range, modulation scheme, resource block (RB), frame format, channel format, etc., than in a 2nd generation (2G) mobile communication system / 3rd generation mobile communication systems ( 3G). Using existing verification methods, it is not possible to verify some specific signal formats, which leads to an increase in the number of unexplored areas. Therefore, the existing method for checking the radio frequency indicators of the mobile terminal is characterized by a relatively large number of unexplored areas.

DETAILED DESCRIPTION

Technical solutions in the embodiments of the present invention will be described below clearly and completely in conjunction with the graphic materials referred to in the embodiments of the present invention.

In embodiments of the present invention, a signal verification system is provided. In FIG. 1 is a block diagram of a verification system according to one embodiment of the present invention. As shown in FIG. 1, the verification system may include a control device 11, user equipment (UE) 12 and a verification device 13. The control device 11 is connected to the UE 12 and the verification device 13, respectively. A communication connection is established between the UE 12 and the test device 13.

In FIG. 1, the control device 11 is generally configured to control the UE 12 and the verification device 13 during the signal verification process. The control device 11 may be a personal computer (PC) or a server.

In addition, the UE 12 is connected to the verification device 13 via a radio frequency communication link for establishing a radio communication. The UE 12 and the test device 13 receive the test result of the checked indicators by checking the radio signal between the UE 12 and the test device 13. The UE 12 can be a mobile phone, tablet, etc. The test device can be a measuring device.

The following is another example verification system. In FIG. 2 shows an alternative block diagram of a verification system according to one embodiment of the present invention. As shown in FIG. 2, the verification system comprises a PC, a UE, and a meter. The PC is connected to the meter via the universal interface bus (GPIB) or the Transmission Control Protocol / Internet Protocol (TCP / IP) for controlling the meter. The PC is connected to the UE via a universal serial bus (USB). The PC sends commands to the UE to control the UE. The antenna interfaces ANT0 and ANT1 of the equipment of the UE are respectively connected to the radio frequency interfaces RF1COM and RF3COM of the measuring device via RF communication lines. The radio frequency interface RF1COM in FIG. 2 is denoted by ⑤, and the radio frequency interface RF3COM in FIG. 2 is denoted by ⑥. Thus, radio communication is established.

According to embodiments of the present invention, in the above verification system, the UE 12 is configured with the following capabilities. UE 12 receives the sequence parameters sent by the control device 11 and corresponding to the checked indicators. UE 12 generates an uplink signal based on a format parameter in the sequence parameter and generates a downstream test sequence based on the verification parameter in the sequence parameter. The UE 12 sends an uplink signal to the verification device 13 and initiates an uplink verification by the verification device 13 based on a pre-generated upstream verification sequence. The UE 12, based on the downstream verification sequence, checks the downstream signal sent by the verification device 13 to obtain the verification result of the checked indicator.

The control device 11 is configured to receive checked indicators. The control device 11 is configured to generate, based on the checked indicator, a sequence parameter for the UE 12 corresponding to the checked indicators, and send the sequence parameter to the UE 12, as well as generate a sequence parameter for the test device 13 corresponding to the checked indicator, and send the sequence parameter to the verification device thirteen.

Below, with reference to the above verification system, a signal verification method described in embodiments of the present invention is described.

In FIG. 3 is a flowchart of a signal verification method according to one embodiment of the present invention. As shown in FIG. 3, a signal verification method includes the steps described below.

In step S301, the control device receives each indicator to be checked; on the basis of the indicator being tested, generates a sequence parameter corresponding to the indicator being tested for the UE and sends the sequence parameter to the UE, and on the basis of the indicator being tested, it generates a sequence parameter corresponding to the indicator being tested for the test device and sends the sequence parameter to the testing device.

The indicator under test may contain the error vector amplitude (EVM), adjacent channel leakage coefficient (ACLR), power, frequency deviation, automatic gain control (AGC), received signal strength indicator (RSSI), received reference signal power (RSRP), block coefficient errors (BLER), system parameter N0 (for displaying received interference), etc., to which the present invention is not completely limited.

After receiving the checked indicators, the control device searches for the corresponding sequence parameter of each checked indicator and receives the corresponding sequence parameter of each checked indicator. The sequence parameter may comprise a sequence parameter for the UE and a sequence parameter for the tester.

The sequence parameter for the UE contains a format parameter and a verification parameter. The format parameter specifies the format of the upstream signal sent by the UE to the verification device. The format parameter may comprise a modulation scheme, frequency range, number of resource blocks (RB), RB offset, frame structure, channel format, data content, etc. The channel format may include a physical uplink control channel (PUCCH) and a physical uplink common channel ( PUSCH), etc., and the data content contains ALL0, ALL1 or a random code (PN9), etc. The verification parameter specifies the verification time for the UE to verify the downstream signal and the type of indicator being tested. The type of indicator under test may contain AGC, RSSI, RSRP, BLER, N0, frequency deviation, etc.

The sequence parameter for the test device contains a format parameter and a verification parameter. The format parameter specifies the format of the downstream signal, and the format parameter can be the cell power, frequency channel number, frequency range, modulation scheme, etc. The test parameter specifies the test time so that the test device checks the upstream signal and the type of indicator being tested. The type of indicator under test may contain EVM, ACLR, power, frequency deviation, etc.

After determining the sequence parameter for the UE and the sequence parameter for the test device, the control device sends the sequence parameter for the UE to the UE and sends the sequence parameter for the test device to the test device.

In step S302, the UE receives a sequence parameter corresponding to the indicator being tested and generated by the control device for the UE, and generates an upstream signal based on a format parameter in the sequence parameter, and also generates a downstream test sequence based on the verification parameter in the sequence parameter.

In one embodiment, step S302 further includes receiving, by the test device, a sequence parameter corresponding to the indicator being tested and generated by the control device for the test device, and generating a downstream signal based on a format parameter in the sequence parameter, and generating an upstream test sequence based on the check parameter in sequence parameter.

In particular, after the UE receives the sequence parameter for the UE and the test device receives the sequence parameter for the test device, since the sequence parameter for the UE generated by the control device corresponds to the sequence parameter for the test device generated by the control device, the upstream signal generated by the UE corresponds to the upstream test sequence generated by the test device and the downstream signal generated nth test device corresponds to the downstream test sequence generated by the UE.

Both the ascending verification sequence and the descending verification sequence specify the time of verification of each indicator being checked. In FIG. 4 is a timing chart of the upstream and downstream test sequences in LTE according to one embodiment of the present invention. As shown in FIG. 4, the test sequences specify the type of ascending indicator to be checked and the type of descending indicator to be checked at each moment of time and contain the corresponding ascending and descending format parameters. For downstream traffic (RX, receive), the downstream signal of the meter is configured exactly according to the sequence parameter, and the UE is in a continuous measurement state, so that the UE receives data at any given time. For RX, the sequence parameter may contain RSRP, AGC, N0, and BLER. For upstream traffic (TX, transmission), the format parameter of the upstream signal sent by the UE at each time point is specified, and the corresponding measuring device measures the upstream signal with a suitable upstream test sequence in accordance with the signal formats. For TX in the first main frequency band, the frequency range is 20 MHz, 10 MHz, and 5 MHz in time, and the channel has a high frequency, then a middle frequency, and then a low frequency. During the verification process, the first verification element is performed in the first 20 ms of the upstream verification sequence, all resource blocks are checked (FULL RB), and the tested indicators in the upward verification sequence contain maximum power (MaxPower), EVM, ACLR, spectral emission mask (SEM), offset IQ, Extended Spectral Uniformity (ESF). The second verification element is performed in the next 60 ms, one resource block (1 RB) is checked, while the RB offset is the 0/49/99 offset, and the checked indicators contain MaxPower, EVM, ACLR, SEM, IQ offset, and ESF. The third check element is performed in the next 60 ms and 18 resource blocks (18 RB), while the RB offset is the 0/32/82 offset, and the indicators checked include Maxpower, EVM, ACLR, SEM, IQ offset, and ESF. The fourth check element is performed in the next 20 ms, 1 resource block (1 RB) is checked, while the RB offset is an offset of 0, and the indicators checked include MaxPower, EVM, ACLR, SEM, IQ offset, and ESF. The fifth test item is performed in the next 40 ms, and the test indicator is the minimum power (MinPower). The sixth check element is performed in the next 40 ms, and the checked indicator is an IQ offset. The seventh check element is performed in the next 20 ms, and the checked indicator is a time mask.

In step S303, the UE sends an uplink signal to the test device and initiates the sending device to send the downstream signal to the UE. The verification device checks the upstream signal based on the upstream verification sequence, and the UE checks the downstream signal based on the downstream verification sequence. Thus, the result of checking the checked indicators is obtained.

To achieve sequence synchronization, the UE sends an upstream signal to the tester and initiates the tester to send a downstream signal to the UE, while the upstream test sequence and the downstream test sequence are performed simultaneously, thereby achieving sequence synchronization and ensuring the correct test result.

In addition, to obtain a test result of the checked indicators in an alternative embodiment, the test device checks the upstream signal based on the upstream test sequence by checking the upstream signal based on the correspondence between the types of checked indicators and the time in the upstream test sequence; and the UE checks the downstream signal based on the downstream test sequence to obtain a test result of the checked indicators by checking the downward signal based on the correspondence between the types of checked indicators and the time in the downstream test sequence.

As indicated above, the upstream signal corresponds to the upstream test sequence, and the downward signal corresponds to the downstream test sequence. Therefore, after the sequence synchronization between the UE and the test device has been achieved, the test result of the checked indicators can be obtained in an exact manner when the UE performs a downstream test sequence and the test device performs an upstream test sequence.

To further obtain a more accurate test result of the checked indicators in an alternative embodiment, after sending an upward signal to the test device and before receiving the result of checking the checked indicators, the method further includes configuring a sequence parameter in the physical layer (PHY) or the medium access control (MAC) layer ; and / or configuring a sequence parameter in a logical channel or transport channel; and / or directly configuring the radio frame parameter.

In FIG. 5 is a structural diagram of a radio access protocol system according to one embodiment of the present invention. As shown in FIG. 5, the structure of the radio access protocol system includes layer 1, layer 2 and layer 3. Layer 1 is the physical layer (PHY), layer 2 is the media access control (MAC) layer, and layer 3 is the radio resource control (RRC) layer . Transport channels are between the PHY layer and the MAC layer, and logical channels are between the MAC layer and the RRC layer.

The entire mobile communications architecture contains three layers. Since the radio frequency indicators are not associated with the RRC layer, the radio frequency indicators are activated at the boundary between the MAC layer and the RRC layer, in the MAC layer and at the boundary between the MAC layer and the PHY layer to form a non-signal check sequence. The action of the radio frequency signal at any time can be determined by excluding signal interactions from a non-signal test sequence, while the measuring device can scan the signal at all time points or downstream signals of different formats can be introduced, thereby ensuring the integrity of the MAC layer and the PHY layer and uniformity RF indicator checks.

The boundary between the PHY layer and the MAC layer and the boundary between the PHY layer and the RRC layer are used as starting points for the construction of sequences in order to implement a non-signal verification sequence.

The construction is implemented in accordance with hierarchical logic. The specific number of construction levels is determined by the architecture of the hardware and software implementation of the entire communication protocol package and the points that need to be monitored. In this case, we can assume that the construction is implemented at three levels.

At the first level, the parameters related to the process in the PHY / MAC layers defined by the protocol specifications are configured in such a way as to form a non-signal verification sequence in order to verify that the process in the PHY / MAC layers defined by the protocol specifications is correctly implemented in During the process, specific indicators of the RF characteristic appear in the PHY layer / MAC layer. For example, the data source ALL0 / ALL1 / PN9 is configured; different coding schemes and filtering coefficients are configured; RB units, debug mode, subframe ratio, antenna, etc. are configured so that the sequence parameter is configured in the PHY / MAC layer. During the verification of checked indicators, the result of the verification of checked indicators related to the hardware by which codes are executed is more accurate.

At the second level, the parameters related to logical channels / transport channels are tuned in such a way as to form a non-signal test sequence in order to verify the correct implementation of the channels and check specific indicators of the radio frequency characteristic when the parameters related to the channels are finally implemented in the radio frequency signal. For example, PUSCH is removed and reserved only for PUCCH to observe the PUCCH signal indicator; the physical channel indicator of the control format indicator (PCFICH) is monitored separately; for PUSCH or PUCCH, a specific UCI parameter is configured; and observe the radio frequency signal indicator and so on, thereby ensuring the accuracy of the checked indicators for PUCCH.

At the third level, the parameters related to the radio frame are directly tuned so as to form a non-signal test sequence in order to check the indicators of the radio frequency characteristics of the hardware. In this case, the check is no longer limited to the PHY layer defined by the protocols, and is based on a method for checking a radio frequency demonstration mask (DEMO), in which the radio frequency indicators in the frequency domain / time domain are checked by adjusting the frame length, modulation scheme, data source, etc. .

At each of the three levels, attention is paid to a specific aspect. The non-signal verification sequence at the first / second level is aimed at the behavior of the entire PHY / MAC layer defined by the protocol specifications. The non-signal verification sequence at the third level focuses more on different hardware scenarios.

In step S304, the control device receives a test result of the checked indicators from the UE and a test result from the test device, respectively.

In an alternative embodiment, before step S304, the method may include sending the control device to the UE and the test device, respectively, the request command, wherein the UE sends the test result to the control device and the test device sends the test result to the control device.

When applied in practice, the ascending and descending test sequences are performed in a specified period of time, so that it is possible to predict when the operation of the control device will be completed. After completing the sequence, the control device checks the measuring device to determine the practical state and then receives the measurement data of the measuring device and the measurement data of the UE.

By this time, the checked indicators were checked, and the control device received the result of checking the checked indicators.

In a method and apparatus for checking signals, as well as in a computer storage medium according to embodiments of the present invention, to satisfy the verification requirements of each indicator to be checked, the control device provides a sequence parameter for each indicator to be checked. Based on the format parameter and the test parameter in the sequence parameter, the signal tester generates an upstream signal corresponding to the format parameter and a downstream test sequence corresponding to the test parameter, respectively. Thus, the upstream signal of the signal tester and the upstream test sequence of the tester are consistent with each other, and the downstream test sequence of the signal tester and the downstream signal of the tester are consistent with each other. Only when the upstream signal sent by the signal tester matches the upstream test sequence in the tester, the tester can measure the downstream signal tester. Only when the downstream signal sent by the test device matches the downstream test sequence in the signal tester, the signal tester can measure the test downstream indicator. Therefore, when the signal tester sends an uplink signal to the tester, sequence synchronization between the signal tester and the tester is achieved, and the signal tester and the tester perform a downstream test sequence and an upstream test sequence, respectively. Thus, the signal tester can check the downstream signal based on the downstream test sequence that corresponds to the downstream signal, and can also synchronously activate the test device to test the upward signal based on the upstream test sequence that corresponds to the upstream signal, so that the test result is checked indicator, and thereby satisfy the requirements for checking the indicator being checked, eliminating unexplored other areas when checking the radio frequency indicators of the mobile terminal, and the verification requirements are additionally satisfied.

The above communication method will be described below with reference to the side of each device in the signal verification system.

In an alternative embodiment, to obtain a test result of the checked indicators, step S603 is implemented as follows. The step of activating a test device with an upstream signal verification based on a pre-generated upstream verification sequence includes activating a test device with an upstream signal verification based on the correspondence between the types of indicators checked and the time in the upstream verification sequence. The step of checking the downstream signal sent by the test device based on the downstream test sequence includes checking the downstream signal based on the correspondence between the types of indicators checked and the time in the downstream test sequence.

In an alternative embodiment, to obtain a more accurate verification result after sending an upward signal to the verification device and before receiving the verification result of the checked indicators, step S603 of this method further includes configuring a sequence parameter in the physical layer or the medium access control layer; and / or configuring a sequence parameter in a logical channel or transport channel; and / or directly configuring the radio frame parameter.

In a method and apparatus for checking signals, as well as in a computer storage medium according to embodiments of the present invention, to satisfy the verification requirements of each indicator to be checked, the control device provides a sequence parameter for each indicator to be checked. Based on the format parameter and the test parameter in the sequence parameter, the signal tester generates an upstream signal corresponding to the format parameter and a downstream test sequence corresponding to the test parameter, respectively.

INDUSTRIAL APPLICABILITY

In a method and apparatus for checking signals, as well as in a computer storage medium according to embodiments of the present invention, to satisfy the verification requirements of each indicator to be checked, the control device provides a sequence parameter for each indicator to be checked. Based on the format parameter and the test parameter in the sequence parameter, the signal tester generates an upstream signal corresponding to the format parameter and a downstream test sequence corresponding to the test parameter, respectively. Thus, the upstream signal of the signal tester and the upstream test sequence of the tester are consistent with each other, and the downstream test sequence of the signal tester and the downstream signal of the tester are consistent with each other. Only when the upstream signal sent by the signal tester matches the upstream test sequence in the tester, the tester can measure the downstream signal tester. Only when the downstream signal sent by the test device matches the downstream test sequence in the signal tester, the signal tester can measure the test downstream indicator. Therefore, when the signal tester sends an uplink signal to the tester, sequence synchronization between the signal tester and the tester is achieved, and the signal tester and the tester perform a downstream test sequence and an upstream test sequence, respectively. Thus, the signal tester can check the downstream signal based on the downstream test sequence that corresponds to the downstream signal, and can also synchronously activate the test device to test the upward signal based on the upstream test sequence that corresponds to the upstream signal, so that the test result is checked indicator, and thereby satisfy the requirements for checking the indicator being checked, eliminating unexplored other areas when checking the radio frequency indicators of the mobile terminal, and the verification requirements are additionally satisfied.
