Abstract: A system and method for providing communications with a Low Earth Orbit (LEO) satellite constellation using a non-omnidirectional antenna is disclosed. A system and method for determining blockages around a non-omnidirectional antenna for use with a Low Earth Orbit (LEO) constellation is disclosed. The method including: receiving System Information (SI) including ephemeris data for satellites in the LEO constellation; receiving a segment division that divides a ground about the antenna into segments; and determining a segment blocking information for the antenna.

Abstract: A method comprises monitoring, by a control module of a wireless communications terminal, factors related to a first data path for transmission/reception of data communications by the wireless communications terminal over a wireless data communications network. The control module then determines that the first data path is affected by condition(s), by determining that at least one of the factors satisfies a predetermined state reflecting the condition(s) affecting the first data path. The control module then determines a second data path, wherein the second data path is not affected by the conditions affecting the first data path. The control module then switches from the first data path to the second data path for the transmission/reception of the data communications by the wireless communications terminal over the wireless data communications network.

Abstract: A system and method for the efficient use of satellite radio modems and satellite bandwidth is disclosed. In the system and method, a satellite radio modem is used for PRACH requests, each PRACH request occupying 31.25 kHz in a packet data transfer channel. The packet data transfer channels can be either 125.0 kHz or 156.25 kHz. Therefore, four PRACH requests can be transmitted in any one packet data transfer channel. The packet data transfer channels are broken into eight time slots, and one time slot in each channel (either the odd frame or even frame) is dedicated to a PRACH request. A satellite radio modem for PDCH transfers is dedicated for each channel. The satellite radio modem assigned to receive the four PRACH requests is timeshared over 16 channels, thereby reducing the amount of satellite radio modems that would otherwise have been needed, had the PRACH request transmissions utilized a dedicated modem for each PRACH request, for each channel.

Abstract: In a medium earth orbit (MEO) satellite system, an embodiment of the present invention employs a system and method for administering mobility management issues for mobile terminals, via a network of base station controllers. The mobility management issues, for example, paging, routing, and handover of communication signals are administered between the base station systems without having to be routed through the serving general packet radio service support node (SGSN).
