In some embodiments, a system automates drive testing of an Open RAN network using a webserver and a script for a test equipment. For example, the system generates a drive testing route to assign one or more testing equipment based on the prior signal information from prior tests to reduce the resources utilized for network evaluation. In some embodiments, the system generates a drive testing route based on information about a phase of deployment such as after installation of a Radio Unit, changing parameters of the signal on the Radio Unit, or the like. In some embodiments, the system evaluates information received from the testing equipment to determine whether the results meet the testing specification automated processes performed using discretion of a human. In some embodiments, the system determines whether the results are desired in a specific location in a cell site based on the call quality or signal strength data stored in a database without human intervention. In some embodiments, the system automates the analysis and reporting of test data received from the test equipment without intervention of the user.
In some embodiments, the system determines whether further information at a location in the cell site is desired based on data from prior tests to redirect resources such as a test drive vehicle to the location. In some embodiments, the system reassigns drive test locations to a different testing device based on failure of a task at the location. In some embodiments, the system provides logs of prior tests which are usable by drive future tests or help trouble shoot errors in the network instead of a random test drives to identify errors. In some embodiments, the system is able to use a combination of a mobile test unit and a fixed test unit at a location to automate and reduce the effort in optimizing performance of the network.

In some embodiments, the web application 110 determines whether the drive test results meet the test specification. In some embodiment, the web application 110 determines whether the drive test result meets the specification based on a threshold. In some embodiments, the threshold is based on the number of tests run and the number of tests that resulted in information indicating acceptable network performance. In some embodiments, the threshold is based on the results being within a range indicating normal operation for a vendor based on the specifications from the vendor.
In some embodiments, the web application 110, based on a determination that the drive test results meet the drive test specification, sends a request to the drive test equipment to relocate to a second test location on the drive test route.

At operation 314, the controller determines whether the drive test results meet a drive test specification. In some embodiments, the drive test specification includes information about the tests and the data that is expected from the test. In some embodiments, the controller determines that the drive tests results do not meet the drive test specification in response to failure to collect data sufficient to match the drive test specification. In some embodiments, the test results fail momentarily due to different reasons, such as temporary congestion in either a cell site or backhaul, or the like. In some embodiments, the controller marks a test result as failed based on other information received from the point test device close to the drive test location. In some embodiments, in response to a determination that the drive test failed, the controller instructs the drive test to be repeated. In some embodiments, in response to a determination that the drive test failed, the controller generates instructions for a repair/replacement crew to visit the location of the failed drive test to replace or repair hardware at the location. In some embodiments, in response to a determination that the drive test failed, the location is selected as a subset location for a future drive test. In some embodiments, in response to a determination that the drive test failed, the location is selected to have fixed point test equipment installed to facilitate future monitoring of the location.
