Abstract: This paper firstly introduces the basic concept of handover in TD-SCDMA system. At the present time, under such circumstances the transportation is diversified and wireless environment is complex, it leads out the basic concept of hierarchical cell structure. On the basis of the HCS, the paper introduces a algorithm of the inter cell handover based on movement speed of UE in TD-SCDMA and the flow of it, in the end, it gives the mechanism to avoid pingpong handover after handover success and the mechanism to punish handover failure.

Key words: TD-SCDMA, handover, hierarchical cell structure, movement speed of UE, sliding window
