LTE dynamic resource allocation algorithm for the next generation mobile communication systems is discussed. Through the analysis on different types of traffic QoS requirements, the QoS parameters of us-er service types are determined and priority levels also established, and QoS is used to display different service time-delays. Meanwhile, the handoff factor is also set up through priority analysis of the cell hand-off users. Thus the modified dynamic resource allocation algorithm based on QoS optimization is further proposed and simulated. Simulation results show that the system performance is effectively improved, mo-reover,the system fairness and cell throughput also increased as compared with traditional algorithms.
