    • A satellite communication system for communicating between a plurality of user terminals is disclosed having at least one satellite which provides multiple beams, a plurality of user terminals that communicate with each other via satellites of said constellation, at least one gateway connected to a public switched telephone network and communicating with at least one user terminal over the satellite communication system wherein each of said user terminals within a given frequency band is distinguished from another of the user terminals employing a combination of time slots and orthogonal codes implemented in a forward and return link. Each of the user terminals is equipped to initiate or receive or terminate packet data messages. Each of said user terminals is handed off from one beam of a satellite to another beam of said satellite. The hand off is predicated on signal strength determined at said plurality of user terminals.
    • 公开了一种用于在多个用户终端之间进行通信的卫星通信系统,其具有提供多个波束的至少一个卫星,经由所述星座的卫星相互通信的多个用户终端,连接到公共交换电话的至少一个网关 网络并且通过卫星通信系统与至少一个用户终端进行通信,其中给定频带内的每个所述用户终端与使用在前向和返回链路中实现的时隙和正交码的组合的用户终端中的另一个进行区分。 每个用户终端被配备来发起或接收或终止分组数据消息。 所述用户终端中的每一个从卫星的一个光束切换到所述卫星的另一个光束。 切换基于在所述多个用户终端处确定的信号强度。
