On special challenges of RAN is the the air interface. All user equipment are connected through air interface to the radio head (RH), based station and then to the network. Most of the existing CI/CD procedures can only deploy a piece of software to simulating the air interface and UE. This approach might be ok for high level network functions, but it will be a critical issue for RAN CI/CD. Without RF, uu and real UE in the loop, the test or verification is not complete.
Traditional RAN verification has two parts of works, one is manual lab testing, and another is field test or drive test. In both cases, heavily manual interventions are required. A certain level of automation is possible, but only on a very low level, for example, pre-defined controls carry out step by step, and may repeated, no matter whatever could happen. With such limitation, it is impossible to design some intricate test case to verify RAN features when take effect only under certain RF conditions.

We provide ORAN test SDK solution to address challenge.

We open up the test UE access layers and wrapped them up into API . The ORAN CICD pipeline can call the test and control functions on demand, with the return of test results.
