摘要
A satellite-based, world-wide cellular messaging system transmits paging messages to pagers. The messages are transmitted during a guard- band time-slot of a compatible world-wide cellular telephone system. In order to achieve better penetration, the satellites boost their transmit power for paging messages. One or more paging carrier frequencies may be used to accommodate differences in paging demand among different terrestrial cells.
