摘要：
Disclosed herein is a handover method and apparatus for providing mobile Internet Protocol Television (IPTV) service over wireless communication networks. The handover method includes checking whether the strength of a signal received from a first base station of a serving first wireless network falls within a predetermined first threshold range; if the strength of the signal falls within the range, checking whether the strength of a signal received from at least one base station of a second wireless network is higher than a second threshold value required for handover; estimating the velocity and direction of a Mobile Node (MN) using location information received from a satellite; predicting a handover target base station using the estimated velocity and estimated location information; and, if the predicted target base station is one of base stations having the second threshold value, performing handover to the target base station.
摘要（中）：
本文公开了一种用于通过无线通信网络提供移动因特网协议电视（IPTV）服务的切换方法和装置。 切换方法包括：检查从服务第一无线网络的第一基站接收的信号的强度是否落在预定的第一阈值范围内; 如果信号的强度落在该范围内，则检查从第二无线网络的至少一个基站接收到的信号的强度是否高于切换所需的第二阈值; 使用从卫星接收的位置信息来估计移动节点（MN）的速度和方向; 使用估计速度和估计位置信息来预测切换目标基站; 并且如果预测的目标基站是具有第二阈值的基站之一，则执行到目标基站的切换。
