And file is uploaded to PC specified directory by ftp；
Step S205: pair of the Channel Processing intermediate node data of base station platform software notification base station physical layer software collection
File upload is answered to finish.
Specifically, base station physical layer software read test file, progress Command Line Parsing extract corresponding survey in step s 201
Try the data of example Base-Band Processing.
The relevant configuration of parsing is preferably reconstructed into L3, L2 message, and then simulates true L3, L2 message by physical layer software
It is handled.
Further, base station physical layer software carries out Base-Band Processing according to relevant configuration and acquires channel in step S202
Handle intermediate node data.
Base station physical layer software plans good related shared drive, base station physical layer software collection and step to platform software in advance
The corresponding Channel Processing intermediate node data of original intermediate node data for including in original intermediate node data file in rapid S01
Shared drive is written in the same format.
Further, base station physical layer software notification base station platform software test example is disposed in step S203.
Further, node data each in shared drive is respectively written into and corresponds to text by base station platform software in step S204
File is simultaneously uploaded to PC specified directory by ftp by part.
The file designation mode of base station platform Software Create is CaseN_XYZ_phy_output.txt, and wherein N represents N
A test case, XYZ represent the sub-function module of some channel of Channel Processing.
Further, in step S205 base station platform software notification base station physical layer software collection intermediate node data
File upload finishes.
After base station side software has handled a test case according to Fig. 3, next test case then is executed by Fig. 3, until surveying
All test cases that examination example is concentrated are disposed.
All test cases execute step S3 after being disposed, the matlab program run on PC carries out each node data ratio
Compared with record test result.
The matlab program run on PC is adopted according to dependence test example under test case sequential query ftp server specified directory
Whether the respective file of the Channel Processing intermediate node data of collection collects, and starts data comparison after collecting, until all test cases
It has handled.Think that the test case passes through if test case whole node data is consistent.If the data of some node are different
Cause then thinks that the test case does not pass through, and matlab program updates unsanctioned test case sum and records not by the sequence of test case
Number and corresponding sub-module name.
Then step S4 can be performed, test result is forwarded by mail server after being disposed and gives phase by test case collection
Close exploitation and tester.
Test result is directly counted by matlab program, including test case sum and unsanctioned test case it is total, do not lead to
Cross the serial number and corresponding sub-module name of test case.
Matlab program has counted and the result is transmitted directly to related development and test after the processing result of test case collection
Personnel.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to example, those skilled in the art should understand that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention, should all cover
