As an important process of UE initial access and uplink synchronization, the random access procedure is simplified and modified on the basis of LTE system in NB-IoT. Through the random access procedure in LTE system, a random access procedure based on competitive mode which is currently supported by NB-IoT is deeply analyzed and a conformance test platform based on TTCN-3 is built to verify the consistency of the random access procedure with the standard.
