| 摘 要： | 针对低轨卫星移动通信系统用户在多星覆盖的情况下的位置注册问题，提出了仰角和覆盖时间加权策略。这种策略既可保证注册卫星覆盖移动终端的时间长，又可保证移动终端处于低仰角的概率低，保证较好的寻呼信道条件，减少了位置更新和寻呼移动终端的信令开销。

| Abstract: | In LEO satellite network, MTs are always covered by more than one satellite simultaneously. A satellite selection strategy for the MT to register its location is presented in this paper. It considers both the elevation angle factor and the time during which the MT remains covered by the same satellite. Performance of the strategy indicates that it reduces the MT location update rate and the probability of paging MT in the condition of lower elevation angles. |
