Group radio communication system with shared bi-directional communication channel

摘要：

A point-to-multipoint (PTM) radio communication system (20`) includes a cellular radio infrastructure (22) having base stations (32) implemented in satellites (34) placed in low earth orbits (38). PTM subscriber radios (24) share common cellular radio infrastructure (22) multipoint channels (52) to engage in a common PTM communication session while the cellular radio infrastructure (22) also conveys point-to-point communications. The shared multipoint channels (52) are operated in according with different protocols to deliver system information to PTM subscriber radios (24), to provide access to PTM subscriber radios (24), to provide synchronization, to originate a PTM monolog and to be one of many targets of a PTM monolog.

摘要（中）：

点对多点（PTM）无线电通信系统（20`）包括蜂窝无线电基础设施（22），其具有实现在放置在低地球轨道（38）中的卫星（34）中的基站（32）。 PTM用户无线电（24）共享公共蜂窝无线电基础设施（22）多点通道（52）以便在蜂窝无线电基础设施（22）也传达点对点通信的同时参与公共的PTM通信会话。共享多点信道（52）根据不同协议进行操作，以将系统信息传送到PTM用户无线电（24），以提供对PTM用户无线电（24）的接入，以提供同步，以产生PTM单声道并成为一个许多PTM单目标的目标。
