When a cell and terminal equipment communicate in a real environment, the cell and the terminal equipment are interfered by other signals of the communication environment, and when the prior art is used for indoor test, external equipment is adopted to send interference signals to simulate the interference in the real environment, but the external equipment needs to be connected with each RRU of the cell, so that the operation is complex and the test efficiency is low; therefore, the embodiment of the invention provides a testing method to improve the performance efficiency of a testing cell.
One of the core concepts of the embodiment of the present invention is that, in the test process, the interference signal for simulating the interference in the real air interface environment is generated by the cell itself, and does not need to be externally connected with external equipment; and further greatly improves the testing efficiency.
Referring to FIG. 1, a flow chart of the steps of one test method embodiment of the present invention is shown; the method comprises the following specific steps:
In a communication system, various interferences exist in a real air interface environment, including co-channel interference, i.e., interference of a communication signal by a signal having a frequency within a frequency passband of the communication signal, and inter-frequency interference, i.e., interference of a communication signal by a signal having a frequency outside the frequency passband of the communication signal. Therefore, before generating the interference signal, the cell may acquire the frequency of the communication signal between itself and the terminal device, so as to generate a corresponding interference signal according to the carrier frequency. The cell communicates according to the frequency configured for the base station when the cell is established, so that the cell can acquire the frequency point information of the cell from the configuration information of the cell in the test process, and the frequency of the communication signal corresponding to the cell is determined according to the frequency point information.
And 102, determining a test scene type corresponding to the test, and determining corresponding interference information according to the test scene type.
The interference in different real air interface environments is different, and the interference degree on the communication signal is also different, for example, the interference degree on the communication signal is large if some real air interface environments have more interference in urban areas, and for example, the interference degree on the communication signal is small if some real air interface environments have less interference in suburban areas; therefore, the embodiment of the present invention is a comprehensive test cell performance, and can simulate the interference in various real air interface environments, that is, it can preset a plurality of test scene types according to requirements, where each real air interface environment corresponds to one test scene type, and each test scene type has corresponding interference information, where the interference information is used to generate a corresponding interference signal, so as to simulate the interference in the corresponding real air interface environment by using the interference signal. Therefore, the test scene type corresponding to the test can be determined according to the requirement of the test, and the interference information corresponding to the test scene type corresponding to the test can be determined according to the corresponding relation between the test scene type and the interference information.
And 103, determining the frequency of the interference signal according to the frequency point information and the interference information.
And 104, generating an interference signal corresponding to the test scene type according to the interference frequency.
And 105, transmitting the interference signal corresponding to the test scene type.
In the embodiment of the present invention, the interference information may include a frequency interval of the interference signal, and may also include other information such as the number of the interference signals, etc.; and then determining the interference frequency of the interference signal corresponding to the test scene type according to the frequency interval in the frequency point information and the interference information. And then generating an interference signal corresponding to the test scene type according to the interference frequency, and transmitting the interference signal corresponding to the test scene type according to the requirement so as to interfere the communication signal between the cell and the terminal equipment.
And 106, calculating the performance parameters of the cell, and testing the cell performance according to the calculated performance parameters.
After the cell sends the interference signal corresponding to the test scene type, interference may be caused to the communication signal between the cell and the terminal device, for example, when the terminal device receives the communication signal sent by the cell, the terminal device may receive interference information, and for example, when the cell receives the communication signal sent by the terminal device, the cell may also receive the interference signal sent by itself; further, according to the condition that the cell or the terminal equipment analyzes the communication signal, calculating various performance parameters of the cell, such as the utilization rate of wireless resources and the like, and then testing the cell performance according to the calculated performance parameters; and judging whether the cell needs to be optimized under the scene of the corresponding test type according to the cell performance. For example, the calculated performance parameters are all higher than the reference performance parameters, it may be determined that the cell performance is better, i.e., the cell does not need to be optimized for the test type scenario.
In the test process, the cell acquires the frequency point information of the cell from the configuration information, determines the test scene type corresponding to the test, and determines the corresponding interference information according to the test scene type; determining the interference frequency of an interference signal according to the frequency point information and the interference information, generating the interference signal corresponding to the test scene type according to the interference frequency, and transmitting the interference signal corresponding to the test scene type; the interference signal is adopted to simulate the interference in a real empty environment, so as to interfere the communication signal between the cell and the terminal equipment; further calculating the performance parameters of the cell, and testing the cell performance according to the calculated performance parameters; the interference signal is generated by the cell itself without adopting external equipment to generate the interference signal, so that the efficiency of testing the performance of the cell is improved.
In another embodiment of the present invention, the interference signals corresponding to different test scenario types are different, that is, the interference information corresponding to different test scenario types is different; the interference information may include a plurality of parameters, such as a transmission power of the interference signal, a number of the interference signals, a frequency of the interference signal, and the like.
Referring to FIG. 2, a flow chart of steps of another test method embodiment of the present invention is shown; the method comprises the following specific steps:
When a cell of a base station is planned, carrier frequencies of communication signals between the cell and terminal equipment are planned for the cell, wherein one cell can correspond to one carrier frequency or a plurality of carrier frequencies. Specifically, during planning, the frequency of each subcarrier can be determined according to the central frequency, the system bandwidth and the frequency interval of each subcarrier, and then each subcarrier is numbered, wherein the numbers are frequency points; and allocating at least one frequency point for each cell, generating frequency point information according to the relationship between the frequency point and the corresponding frequency, and storing the corresponding frequency point information into the configuration information of the cell. For example, suppose the central frequency point of the cell is 2100Mhz, and the system bandwidth is 20 Mhz; the working frequency of the cell is 2090-2110 MHz, and 2100Mhz is located at the center of the working frequency band; in the 20Mhz bandwidth, many sub-carriers are divided, and the sub-carriers are separated by 15kHz, which totally divides 1200 sub-carriers. 15kHz 1200 Mhz 18Mhz, leaving 2Mhz as the guard bandwidth. Then, the 1200 subcarriers are numbered, for example, 1, 2, 3, … …, 1200, and the numbers are frequency points.
Step 202, determining a test scenario type corresponding to the test, and determining corresponding interference information according to the test scenario type.
According to the embodiment of the invention, the interference information corresponding to the test scene type can be set in advance according to the interference conditions corresponding to various real air interface environments, and the mapping relation between the air interface environment and the test scene type is established. Before testing, determining an air interface environment to be tested in the test according to requirements, and determining a corresponding test scene type corresponding to the test according to the air interface environment of the test and a mapping relation between the air interface environment and the test scene type during testing; then determining corresponding interference information according to the test scene type, wherein the interference information can comprise frequency intervals of interference signals, and if a cell corresponds to a plurality of carrier frequency frequencies, the frequency intervals can be intervals of any carrier frequency; further, the interference frequency of the interference signal can be determined according to the frequency point information and the frequency interval, which is as follows:
and 203, determining the carrier frequency of the communication signal between the cell and the terminal equipment according to the frequency point information.
The frequency point information comprises frequency points, frequencies of subcarriers and a corresponding relation between the frequency points and the subcarriers, so that after the frequency point information is obtained, the frequencies of the subcarriers corresponding to the cell can be obtained from the frequency point information, and the frequencies of the subcarriers are determined as carrier frequencies of communication signals of the cell and the terminal equipment. Then, according to the carrier frequency and the frequency interval, an interference signal is generated, which specifically comprises the following steps:
and 204, calculating a difference value or a sum value of the carrier frequency and the frequency interval, and determining the difference value or the sum value as an interference frequency.
In the embodiment of the invention, the frequency intervals of the interference signals corresponding to different test type scenes are different, for example, the frequency interval between the interference signal corresponding to the test scene type I and the cell carrier frequency is 20 kHz; for another example, the frequency intervals between the interference signals corresponding to the test scenario type two and the cell carrier frequency are 40kHz respectively. Thus, a difference value or a sum value of the carrier frequency and the frequency interval can be calculated and determined as an interference frequency; if the cell corresponds to a plurality of carrier frequency frequencies, calculating the difference value or sum value of any carrier frequency and the frequency interval; of course, the difference or sum of each carrier frequency and the frequency interval may also be calculated, and all the differences or sums may be determined as the interference frequency.
Optionally, the interference information further includes the number of interference signals, that is, different test scenario types correspond to different numbers of interference signals, for example, one test scenario type corresponds to one interference signal, and two test scenario types correspond to three interference information; correspondingly, the frequency interval may correspond to the number of interfering signals, i.e. one interfering signal corresponds to one frequency interval. Therefore, if the number of the interference signals is more than one, the difference value or the sum value of the carrier frequency and each frequency interval is calculated, and more than one interference frequency is determined. The type of the interference signal may be various types such as white noise, gaussian noise, etc., and is not limited herein.
And step 206, transmitting the interference signal corresponding to the test scene type by using the transmission power at the transmission time.
In the embodiment of the present invention, the interference information further includes transmission power and transmission time of the interference signal, for example, the transmission power of the interference signal corresponding to the test scenario type three is 10dBm, and the interference signal is transmitted when the cell receives the communication signal; for another example, the transmission power of the interference signal corresponding to test scenario type four is 4dBm, and the interference signal is transmitted when the cell receives the communication signal. Therefore, when the interference signal corresponding to the test scene type is sent, the transmission power and the transmission time of the interference signal corresponding to the interference signal can be obtained from the interference information; and then, transmitting the interference signal corresponding to the test scene type by adopting the transmitting power at the transmitting time.
The embodiment of the invention can test the uplink performance and the downlink performance of the cell, wherein if the downlink performance of the cell is tested, the interference signal can be transmitted at the time of transmitting the communication signal by the cell so as to simulate downlink interference; if the uplink performance of the cell is tested, the interference signal can be transmitted at the time when the cell receives the communication signal so as to simulate uplink interference. The time for transmitting the communication signal by the cell may be any time between the time when the cell prepares to transmit the communication signal and the time when the terminal device completely receives the communication signal; the time for receiving the communication signal by the cell may be any time period between the terminal device sending the communication signal and the cell completely receiving the communication signal; the method can be specifically set according to requirements.
After the cell sends out the interference signal corresponding to the test scene type, the interference can be caused to the communication signal between the cell and the terminal equipment, and further the performance parameter of the cell can be calculated according to the condition that the cell or the terminal equipment analyzes the communication signal; for the uplink interference test, the cell may directly calculate the performance parameters of the cell according to the received communication signals, and for the downlink interference test, after the cell transmits the communication signals, the terminal device may return corresponding feedback signals, and then the cell may calculate the performance parameters of the cell according to the feedback signals. Therefore, the manner of calculating the performance parameter of the cell may be determined by determining whether the transmission time is the time when the cell transmits the communication signal, and if the transmission time is the time when the cell transmits the communication signal, step 208 is executed; if the transmission time is not the time of the cell transmitting the communication signal, step 209 is executed.
Step 209, calculating a performance parameter of the cell according to the received communication signal.
The calculated performance parameters may be compared to corresponding reference performance parameters to determine cell performance.
In the test process, the cell acquires the frequency point information of the cell from the configuration information, determines the test scene type corresponding to the test, and determines the corresponding interference information according to the test scene type; determining the interference frequency of an interference signal according to the frequency point information and the interference information, generating the interference signal corresponding to the test scene type according to the interference frequency, and transmitting the interference signal corresponding to the test scene type; the interference signal is adopted to simulate the interference in a real empty environment, so as to interfere the communication signal between the cell and the terminal equipment; further calculating the performance parameters of the cell, and testing the cell performance according to the calculated performance parameters; the interference signal is generated by the cell itself without adopting external equipment to generate the interference signal, so that the efficiency of testing the performance of the cell is improved.
Furthermore, the embodiment of the invention also generates the interference signal according to the test scene type, namely the interference under different real air interface environments can be simulated, and then the performance of the corresponding cell in different real air interface environments can be tested, thereby the test method is comprehensive.
And after generating the interference signal corresponding to the test scene type, the embodiment of the invention can send the interference performance at the time of transmitting the communication signal in the cell and/or the time of receiving the communication signal in the cell, namely, can simulate the uplink interference and the downlink interference, so as to test the uplink performance and the downlink performance of the cell, thereby further improving the test comprehensiveness.
