Narrow band internet of thing (NB-IoT) is an emerging internet of things technology that is based on cellular networks. Since there is only 180KHz uplink spectrum resource in NB-IoT, it is necessary to optimize the uplink resource allocation in order to obtain as many successful communication devices as possible. However, there is a lack of an uplink resource allocation algorithm that can cope with various situations in existing allocation methods. Therefore, an adaptive uplink resource control algorithm is proposed in the paper. In the algorithm, the base station first estimates the maximum number of accessible devices through exhaustively calculation of the retransmission times, the number of preambles and the size of the transmission data, and then the base station adjusts uplink resource and controls the number of access devices according to the current network load. The simulation results show that compared with the traditional algorithms, the proposed algorithm can maximize the number of successful communication devices in various situations.
