As the test network deployment of the TD-LTE.Betwwen TD-SCDMA and TD-LTE tongether become inevitable tendency.This paper base on the handover strategy

which about TD-SCDMA and TD-LTE network to analysis and research

Combined with the weight of the business operators for different

through the detailed theoretical analysis

the establishment of a new set of TD-SCDMA and TD-LTE system switching between plots in the process mechanism

according to get the size of the profit value network to realize preference which network’s purpose and provide a new hanover method.MATLAB built network model

combining switching strategies on existing in reality scene is simulated.
