The characters of the schemes were pointed out.Then, we introduced a classical schemes called time-based channel reservation algorithm. Based on this scheme we proposed a Preempting Reserved Channel Mechanism based on TCRA. According to the QoS this sell discount wedding dresses mechanism determine a value with which compare the time value when all the channels are reserved and determine whether new calling is accepted. The simulation results show that, compared to TCRA, the proposed strategy can effectively improve the new call blocking, and at the plus size wedding dresses same time provide the network with better QoS guarantees.At last, based on the guaranteed handover scheme, we proposed an insufficiently guaranteed handover new shoes 2010 scheme, which assigns the channels for calling in the time less than a can decrease the new call blocking polo shirts shop probability and improve the cannel available prioritization. Base on the discount wedding dresses scheme of the voice traffic, we extended to the multi-carried and proposed the method to carry out the scheme. The simulation results show the feasibility and availability of the proposed scheme with respective degree based on different traffic load.
