Example one
Fig. 1 is a schematic structural diagram of a base band test system of a base station according to an embodiment of the present invention, which is applicable to testing the base station without modifying a code of the base station. The test system tests each dedicated/shared channel transmission by performing data and signaling interaction on a baseband device to be tested in a base station.
Wherein the base station sets a corresponding baseband device for each covered cell. The baseband device is used for data forwarding based on the scheduling information and for data analysis and generating a corresponding report. For example, the baseband device forwards UE uplink data to other baseband devices. For another example, the baseband apparatus adjusts a channel matrix according to the received channel report of the UE, and feeds back the adjusted channel matrix ID to the UE, and the like. The base station may include a plurality of baseband devices, and each baseband device corresponds to a cell covered by the base station. The baseband device is exemplified by a DSP.
When the test system needs to test a certain baseband device in the base station, the test baseband device in the test system is connected with the uplink and downlink channel loop of the baseband device to be tested.
Specifically, the test baseband device 21 includes: on the test communicating with the downlink channel to be tested
A row channel and a test downlink channel communicating with the uplink channel to be tested; the test baseband device 21 is configured to test the baseband device 1 to be tested through data interaction with the uplink channel to be tested and the downlink channel to be tested.
The downlink channel to be tested and the uplink channel to be tested are channels on the side of the baseband device 1 to be tested. The test uplink channel and the test downlink channel are channels on the side of the test baseband device 21. According to the LTE standard, when testing the test types such as group call service or random access function, the downlink channel to be tested and the test uplink channel, and the uplink channel to be tested and the test downlink channel respectively use a shared channel between the baseband device 1 to be tested and the test baseband device 21.
In addition, in order to conveniently test each baseband device 1 to be tested in the base station, the test baseband device 21 is installed in the base station and communicates with the baseband device 1 to be tested through a modulation and demodulation device.
Specifically, the data interaction between the test baseband device 21 and the baseband device 1 to be tested is performed according to the data interaction mode between the baseband device and the terminal in the base station working state. Because the test baseband device 21 is installed in the base station, the baseband device 1 to be tested and the test baseband device 21 do not need to transmit and receive data by using an antenna array of the base station, but can directly realize uplink and downlink data transmission through the modulation and demodulation device.
In an alternative manner, the test baseband device 21 includes: a data test unit 22 and a scheduling test unit 23. Here, the data testing unit 22 and the dispatching testing unit 23 may be configured in a single DSP, and the data testing unit 22 and the dispatching testing unit 23 are connected through the dispatching interface 232. The test uplink channel of the test baseband device 21 includes: a first uplink channel and a second uplink channel. The first uplink channel is used for transmitting first test data sent by the data test unit 22. The second uplink channel is used for transmitting control information such as uplink signaling and uplink scheduling sent by the scheduling test unit 23.
The test downlink channel of the test baseband device 21 may transmit report data and forwarded test data sent by the baseband device 1 to be tested, and the like at the same time.
In this embodiment, as shown in fig. 2, the data testing unit 22 includes: and testing a first uplink channel in the uplink channels. The scheduling test unit 23 includes: a scheduling interface 232 connected to the data test unit 22, a second uplink channel of the test uplink channels, and the test downlink channel.
More specifically, in order to test the downlink transmission of the baseband device 1 to be tested (i.e. the uplink transmission of the test baseband device 21), the data test unit 22 includes: the first data testing module 221. Correspondingly, the scheduling test unit 23 includes: a first scheduling module 231.
The first data testing module 221 is configured to send first test data to the baseband device 1 to be tested through the first uplink channel based on a testing type, and send first scheduling information and the testing type corresponding to the first test data to the scheduling testing unit 23 through the scheduling interface 232.
The first scheduling module 231 is configured to send the first scheduling information to the baseband device 1 to be tested through a second uplink channel based on the test type; and is configured to receive, through the uplink channel to be tested and the downlink channel to be tested, report data generated by the baseband device 1 to be tested based on the first scheduling information and the first test data, and forward the report data to the first data testing module 221 by using the scheduling interface 232.
The first data testing module 221 performs a test analysis on the received report data based on the first test data and the report data.
The test type refers to any data transmission initiated by the base station based on the first data test module 221 and fed back by the baseband device 1 to be tested in the working process, and includes but is not limited to: a test type for testing random access, a test type for testing cell handover, or a test type for testing channel quality, etc.
The first test data and the first scheduling information are generated by a test case according to the test type. The first scheduling information is used to inform the baseband device 1 to be tested of signaling, synchronization sequence, and/or the like for demodulating the first test data.
The test path formed by the uplink channel to be tested and the test downlink channel includes but is not limited to: a physical shared channel, a physical broadcast channel, a physical indicator channel, etc.
For example, the first data testing module 221 first sends a test type for testing the channel quality and first scheduling information including related signaling for reporting the test channel quality to the first scheduling module 231.
The first scheduling module 231 performs scheduling processing such as transmission protocol encapsulation and transmission time slot selection on the relevant signaling according to the received test type, and sends the relevant signaling to the baseband device 1 to be tested through the second uplink channel. The first data testing module 221 sends the first test data including the channel test data to the baseband device 1 to be tested through the first uplink channel and the downlink channel to be tested. The baseband device 1 to be tested demodulates the first test data from the downlink channel to be tested based on the received first scheduling information, performs channel quality analysis on the received first test data according to the working mode, and according to the analysis result, the baseband device 1 to be tested sends corresponding report data to the first scheduling module 231 through the uplink channel to be tested and the downlink channel to be tested. The report data is fed back to the first data testing module 221 by the first scheduling module 231 through the scheduling interface 232. The first data test module 221 analyzes the issued channel test
And whether the data is matched with the received report data or not is judged, if so, the test of the baseband device 1 to be tested is determined to pass, and otherwise, the test is failed.
For another example, the first data testing module 221 obtains a pusch channel (physical uplink shared channel) use case testing data packet from an external device, where the use case packet includes antenna data and Cmac scheduling information. The first data testing module 221 forwards the Cmac scheduling information to the baseband device 1 to be tested through the first scheduling module 231, and simultaneously sends the antenna data to the downlink channel to be tested of the baseband device 1 to be tested through the first uplink channel. The baseband device 1 to be tested calculates the pusch reporting information according to the received antenna data and the Cmac scheduling information, and feeds back the reporting information to the first data testing module 221 through the first scheduling module 231.
Alternatively, in order to test the uplink transmission on the baseband device 1 side to be tested (i.e. test the downlink transmission on the baseband device 21 side), the data test unit 22 further includes: a second data testing module 222. Correspondingly, the scheduling test unit 23 includes: a second scheduling module 233.
The second data testing module 222 is configured to send the test type and the second test data to the dispatching testing unit 23 through the dispatching interface 232.
The second scheduling module 233 is configured to send second test data to the baseband device 1 to be tested through the downlink channel and the second uplink channel to be tested based on the test type; and is configured to receive the second test data fed back by the baseband device 1 to be tested through the uplink channel to be tested and the downlink channel to be tested, and forward the second test data to the second data testing module 222 through the scheduling interface 232.
The second data testing module 222 performs testing analysis on the downlink baseband transmission of the baseband device 1 to be tested based on the sent second testing data and the received second testing data.
The test type is dependent on the type of traffic which is sent out in the operating mode of the baseband device 1 under test. For example, the test types include, but are not limited to: data forwarding type, etc. In order to test whether the baseband device 1 to be tested is normal in the data forwarding process, the second data testing module 222 sends the second test data to the baseband device 1 to be tested according to the second scheduling information through the communication path between the second scheduling module 233 and the baseband device 1 to be tested. The baseband device 1 to be tested feeds back the second test data to the second scheduling module 233 through the uplink channel to be tested and the test downlink channel according to the pair scheduling information, and the second scheduling module 233 returns the second test data to the second data testing module 222 through the scheduling interface 232. The second data testing module 222 determines the transmission condition of the uplink channel of the baseband device 1 to be tested (i.e. the testing downlink channel of the testing baseband device 21) according to whether the sent and received second testing data are consistent. If the test result is consistent with the test result, the test is determined to be passed, otherwise, the test is determined to be failed.
In addition to the above embodiments, the test case in the test baseband device is adjusted or generated more conveniently. The test system also comprises a test case generating device.
The test case generation device is connected with the test baseband device and used for generating corresponding test data and scheduling information based on test types.
The test case generating device is exemplified by a computer, and the test case generating device and the test machine belt device can be connected through an external interface (such as a USB). Therefore, the tester can flexibly test the baseband device to be tested on site. The invention tests the processing and forwarding of various services of the baseband device to be tested by communicating the uplink and downlink channels of the baseband device to be tested with the uplink and downlink channels of the test baseband device, thereby realizing no need of modifying codes in the baseband device to be tested and reducing the interference of the test on the working mode of the baseband device to be tested. In addition, the dispatching test unit is used for transmitting various test data and report data issued by the baseband device to be tested, so that the baseband device to be tested can be ensured to accurately receive the test data and the test errors are reduced.
