Embodiment
[0053] In the embodiment, it is set that in the heterogeneous converged network of WLAN and WiMAX network, the terminal is at the edge of the WLAN cell, and the process of pre-handover to the WiMAX network is performed in the following steps with t j Indicates the current moment, corresponding to the jth sample point under the discrete time sample, t i As the i-th sample point under the discrete time sample, the value interval is [t j-n , t j ], the lowercase v represents the predicted polynomial or value, and the uppercase V represents the actual polynomial or value. figure 1 It is a flowchart of a heterogeneous network pre-handover method based on mobile prediction, and the method includes:
[0054] 1) The physical delay of the terminal pre-handover is used as the time interval Δt for recording the terminal movement information; according to the built-in GPS of the mobile terminal, its location information is recorded at the time interval Δt, and the location information o...
