A satellite-based, world-wide cellular messaging system transmits paging messages to pagers via multiple beams. A message unit monitors multiple beams, recording the visit information for each beam, and ultimately determines the optimum beam to monitor for messages. The message unit, which conserves battery resources by entering into a sleep mode, synchronizes quickly to its message block when it awakes.

A satellite communication system provides users with global cellular coverage. To facilitate delivery of calls to users having subscriber units, a fixed channel is defined wherein subscriber units are notified of incoming calls. Subscriber units monitor this ring alert channel and examine subscriber unit IDs transmitted in a ring alert message contained therein. When a subscriber unit determines from the subscriber unit ID that a call is being directed to it, it calls into a network to receive a call. Subscriber units also monitor this fixed channel to receive a control channel directory identifying the location of a subscriber unit's broadcast (control) channels.

A synchronizer operates to achieve initial synchronization with a TDMA acquisition signal exhibiting a potentially large Doppler. The synchronizer collects samples of a baseband signal during a timing window. A fast Fourier transform (FFT) is performed on the samples to generate a set of spectral data. The window is moved to an identical point in a subsequent frame and the FFT repeated until a high-confidence spectral data set is obtained. If the spectral data set indicates energy concentrated around a discrete frequency, then that discrete frequency represents an estimate of the acquisition signal's frequency. The timing window's timing parameters represent a time slot estimate of the acquisition signal. If the spectral data set indicates energy spread more or less uniformly over the spectrum, then no estimates are indicated and a new window is positioned at a different point in subsequent frames.

A network of satellites delivers communications through bi-directional communication links between individual ones of the satellites. Each satellite terminates a plurality of links. All satellites are synchronized to recognize a constant duration frame structure. For each link in the network, satellites at both ends of the link simultaneously transmit data communications into their respective ends of the link using the same frequency band. Transmissions into all links supported by a satellite occur simultaneously. The transmissions continue for a duration that is responsive to the distance between the satellites. Transmissions cease for all links supported by a satellite when the communications from the opposing link nodes have nearly propagated the entire distances between the satellites. After ceasing transmissions, each satellite receives the communications previously transmitted from the opposing satellites into the links therebetween.

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.

A distribution network 108 receives simplex communications or pages from any number of user interface nodes (UINs) (202) and distributes the pages to one or more paging outlets provided by page termination nodes (PTNs) (110) and delivery systems (102). The UINs (202) perform the bulk of the processing related to the distributed system of the present invention. Originator services (1000) are provided through UINs (202). Through originator services (1000) callers may place pages or inquire about previously placed pages. In placing pages, page originators can specify options (1102-1104) related to the delivery of pages. Subscriber updating services (1100) are also provided through UINs (202). The updating services (1100) allow a subscriber to alter (802-812) the services provided by the distribution network (108). For example, the subscriber may change delivery addresses (402) which identify the delivery systems (102) through which pages are to be delivered.

Multiple, different, independent constellations (10, 20) of satellites (2, 21-23) share a portion of a common frequency spectrum such as a single carrier frequency. The satellites' antennas (11) may be either multi-beam or omni-directional, while those of earth stations (13, 14) are directional. When interference occurs between communications of a satellite (31) of a first constellation (10) and a satellite (41) of a second constellation (20), any of several interference-mitigation options may be employed, such as the first satellite (31) handing off communications to a second satellite (32) of the same constellation (10), or temporarily suspending communications. The remedial action may occur in response to either predicted or detected interference.
