Abstract: Apparatuses, methods, and systems are disclosed for handling satellite hard feeder link switchover. One apparatus includes a processor and a transceiver that receives a configuration from a mobile communication network, the configuration indicating a transition period required by a satellite connected to a first gateway for feeder link switchover to a second gateway. The processor suspends communication with the mobile communication network at the transition time and resumes communication with the mobile communication network after expiry of the transition duration.

Abstract: A method for reducing frequency interference, and a communication satellite system. The method includes configuring the communication satellite system, determining a first range of areas in which a spatial isolation angle between the LEO satellite and the GEO satellite does not satisfy a minimum spatial isolation angle within service areas of the movable spot beams, enabling the movable spot beams to not enter the areas, and when the movable spot beams of the transmitting and receiving user antennas of multiple adjacent LEO satellites provide services to a same area, calculating a spatial isolation angles between the movable spot beams of the transmitting and receiving user antennas of any two adjacent LEO satellites, and in response to the spatial isolation angle not satisfying the minimum spatial isolation angle, assigning different sub-frequencies to the movable spot beams that do not satisfy the minimum spatial isolation angle.

Abstract: Related to the technical field of communication, validity period determinations are provided. For example, a terminal determines a validity period of ephemeris information, the validity period meeting a synchronization requirement of the terminal. By determining the validity period of the ephemeris information that meets the synchronization requirement, the terminal can ensure the real-time accuracy of the ephemeris information at the terminal, thereby ensuring that a time delay and a Doppler frequency shift calculated by the terminal based on the ephemeris information have only small errors. Since the errors do not exceed a range tolerated by the synchronization requirement, the synchronization performance of the terminal can be guaranteed.

Abstract: Disclosed in the embodiments of the present application are a network access method and apparatus for a terminal, an electronic device and a storage medium. Said method comprises: a terminal determining a beam sweeping interval and a sweeping frequency point, and receiving a base station signal sent or forwarded by a satellite; determining the downlink signal quality of the base station according to the base station signal; and if it is determined, according to the downlink signal quality, that the terminal can successfully find a satellite, executing a network access process of the terminal. In the embodiments of the present application, the downlink signal quality of a base station is determined by means of a base station signal sent or forwarded by a satellite; and it is further determined, according to the downlink signal quality, whether a terminal can successfully find a satellite, without depending on ephemeris information, so that the terminal can accurately and quickly find a satellite for successful access and communication while insuring UE serviceability and prolonging life cycle of the terminal.

Abstract: A radio communication route enables communication from an originating ground station to a destination ground station via one of multiple randomly orbiting satellites with no active attitude control. The ground stations and satellites include multi-feed parabolic antennas for receiving radio signals from and transmitting radio signals in multiple directions. The satellites store an address of a destination ground station from which an initial information signal is transmitted and antenna information identifying the satellite antenna feed on which the initial information signal was received. Plural satellite antennas transmit linking information identifying the satellite to the originating ground station. Data transmissions received at the originating ground station that designate a particular destination are transmitted by the originating ground station using the antenna on which the linking information was received and the satellite retransmits the data transmission using the satellite antenna feed identified by the stored antenna information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device detects a trigger to transmit a message via satellite connectivity, determines one or more alignment opportunities associated with one or more satellites, wherein each alignment opportunity of the one or more alignment opportunities is a time period during which a main lobe of an antenna of the wireless communication device is predicted to be aligned with a line-of-sight (LOS) direction to at least one satellite of the one or more satellites, transitions to a sleep state until at least one alignment opportunity of the one or more alignment opportunities, and transmits the message to the at least one satellite of the one or more satellites during the at least one alignment opportunity of the one or more alignment opportunities.
