Detailed Description
The performance test of the cellular interface of the existing mobile communication network equipment is to perform a data forwarding capability test on the cellular interface under the environment of a mobile communication network, and judge whether the cellular interface has design defects or faults or not by combining the experience of testers on the basis of a data forwarding test result. In practical application, even if a large amount of mobile communication network flow is consumed, whether the cellular interface has an abnormal phenomenon can only be judged, and the fault problem point cannot be directly positioned. Meanwhile, the method is limited by a development cost budget or a maintenance cost budget, and in most cases, only a predetermined number of tests can be carried out on the cellular interface. The insufficient test of the cellular interface increases the difficulty in judging whether the cellular interface has design defects or failure problems, so that the design defects and/or failure hidden dangers of the mobile communication network equipment cannot be found in time.
The inventor finds in research that the existing interface performance test method cannot effectively locate the design defect point and/or the fault problem point of the cellular interface, and is not caused by the fact that the test budget is too low and the test cannot be carried out fully, and the actual reason is that the existing interface performance test method is to carry out overall test on the whole cellular interface as a tested object, and the overall test can only obtain the overall performance of the cellular interface, and judge the possible fault problem point causing the abnormal overall performance of the cellular interface according to experience. Meanwhile, the overall test is based on probability statistics to ensure the validity of the test result, the more the test times are, the more the test result is reliable, and correspondingly, more mobile communication network flow needs to be consumed.
There are many factors that cause the overall performance of a cellular interface to be degraded, for example, the reason that the performance of the cellular interface is insufficient under the conditions of large flow and large byte data test may be a potential fault hazard in hardware, a fault in software, or a problem in communication between the cellular interface and other components of the mobile communication network device, and therefore, the difficulty in determining a fault problem point based on the overall test result of the cellular interface is very large.
Meanwhile, the data forwarding test includes a data receiving process and a process of retransmitting received data, one of the two processes has a problem, which causes performance degradation corresponding to the data forwarding test result, and it cannot be determined based on the data forwarding test result whether a failure problem point is in a software and hardware environment corresponding to the data receiving process or a software and hardware environment corresponding to the process of retransmitting the data.
The inventor discovers that the reasons causing the performance reduction of the cellular interface comprise abnormal communication module driving, abnormal equipment interface driving and abnormal Modem hardware, and fault problem points can be positioned by eliminating one by one if the communication module driving, the equipment interface driving and the Modem hardware are tested independently. Meanwhile, the suspected fault problem point can be directly tested, and the fault problem point can be quickly positioned.
The inventor also finds that the single test of the device interface driver of the cellular interface, the driver of the mobile communication module and the Modem hardware can be realized by sending simulation test data through the data processing module of the network device, namely the single test can not consume the mobile communication network flow.
Based on the above knowledge, the inventor provides an interface performance testing method, device and network equipment. According to the testing method and the network equipment, software and hardware of a cellular interface are divided into a mobile communication module driver, an equipment interface driver and Modem hardware, wherein the mobile communication module driver and the equipment interface driver are subjected to simulation testing based on a data processing module of the network equipment to determine whether fault hidden danger or design defects exist, a service side of the Modem hardware is tested based on AT instruction interaction, and a network side of the Modem hardware is tested based on mobile communication test data. And loopback tests are adopted by the mobile communication module driver, the equipment interface driver and the output node of the service side of the Modem hardware, so that problem points are eliminated step by step, and the accurate positioning of the fault problem points is realized. The test method and the network equipment can also perform priority test on suspected problem points, and realize the quick positioning of the fault problem points.

According to the method, a cellular interface of mobile communication network equipment is divided into a driver layer and a Modem hardware layer according to a functional structure, wherein the driver layer comprises an equipment interface driver layer and a communication module driver layer.

The communication module driver layer 511 and the device interface driver layer 512 may be considered as a driver layer 510 in combination.

In summary, the method, the apparatus and the network device for testing interface performance provided in the embodiments of the present invention are not limited to performing performance test on the cellular interface of the mobile communication network device having the USB device interface, but are also applicable to performing performance test on the cellular interface of the mobile communication network device having the RIC device interface.
According to the interface performance testing method, device and network equipment provided by the embodiment of the invention, the cellular interface is divided according to the functional structure, the high-flow and high-pressure deep loopback test is carried out on the test data generated by the divided driving layer based on the self, and the AT instruction interaction test based on the AT instruction set is carried out on the divided Modem hardware layer. Therefore, design defects and fault hidden dangers of a communication module driving layer, an equipment interface driving layer and a Modem hardware layer can be found as much as possible, design defects and fault points are positioned, the design quality and the maintenance quality of a cellular interface are improved, and the user experience of network equipment is improved; meanwhile, the dependence of cellular interface test on the mobile communication network can be reduced.
The cellular interface is divided into a communication module driving layer, an equipment interface driving layer and a Modem hardware layer, so that a more adaptive test scheme can be further formulated according to the characteristics of each layer, the test result can better reflect the actual condition of each functional part of the cellular interface, and the fault problem point is more accurately positioned, for example, when the protocol stack overflows to the same or similar performance representation when the cellular interface is used, the loopback test can be directly carried out on the equipment interface driving layer, and the fault problem point is quickly positioned.
On this basis, since the fault problem point location test is already performed on each functional module of the cellular interface before the cellular interface is subjected to the overall test, the overall test of the cellular interface only needs to perform a simple performance test, and therefore, the cellular interface overall test of the first embodiment of the invention only needs to consume little mobile communication network data traffic, so that the test cost of the cellular interface performance test is further reduced.
