In wireless networks, the uncertainty of terminal mobility causes great inconvenience to the resource management of wireless networks. In this paper, the motion trajectory of the terminal is expressed in the form of Cell sequence, and a Ziv-Lempel motion sequence processing algorithm based on the symbol is proposed. The sequence context relationship obtained by the algorithm can effectively predict and track the movement of the terminal. On this basis, a simpler scheme of resource allocation and reservation is constructed, which has a strong Qo S guarantee ability, a low probability of handover failure and a low probability of new call blocking, and a high reserved resource utilization rate
