发明名称 Global mobile paging system
摘要 A communications system (10) includes at least one satellite (105), at least one terrestrial gateway (103) capable of being bidirectionally coupled to the at least one satellite, at least one terrestrial paging system (109), and at least one user unit (106) capable of being wirelessly coupled to the terrestrial gateway, through the at least one satellite, or to the terrestrial paging system. The gateway includes a paging system (300) for receiving a page message for the user unit, for storing the received page message, and for selectively delivering the received page message to the user unit through the satellite system or through the terrestrial paging system. The gateway is bidirectionally coupled to the terrestrial paging system through the at least one satellite, a virtual gateway (107), and a pager interface unit (108). The pager interface unit includes a pager message and retrieval system (108a) for storing a page message until it is determined that the page message can be one of successfully delivered or not successfully delivered to the user unit via the terrestrial paging system. Stored page messages can be later recalled and delivered to the user.
