The present invention relates to the field of satellite communications, and in particular to a method for handover of a satellite base station, a terminal, the satellite base station, and a storage medium, for use in solving the problem that the current method for handover of the satellite base station is not accurate. In embodiments of the present invention, a terminal determines a pitch angle when accessing the satellite base station; and if the pitch angle is determined within a preset range, the terminal performs inter-satellite handover. Because in the embodiments of the present invention, the terminal can determine, according to the pitch angle and the preset range, whether to perform handover of accessing the satellite base station without additionally calculating other reference information, implementation of a system is simple, and a timing when the terminal needs to perform handover of the satellite base station can be accurately determined according to the preset range, so as to achieve quick and accurate handover of the satellite base station and improve determination efficiency of handover of the satellite base station.

The signal continuous coverage method for a target area, which is used for an aircraft bearing a communication base station, comprises: acquiring the flight height, the farthest distance of a flight trajectory, the roll angle and a preset center position of a target area of the aircraft; acquiring a vertical half-power angle of an airborne antenna of the communication base station and a farthest signal coverage point position relative to the preset center position; on the basis of the flight height, the farthest distance of the flight trajectory, the roll angle, the preset center position, the vertical half-power angle and the farthest signal coverage point position, determining a target downward inclination angle of the airborne antenna; and adjusting a current downward inclination angle of the airborne antenna to the target downward inclination angle so as to enable a signal continuous coverage area to comprise the target area.

Provided in embodiments of the present disclosure are a wireless communication method, a terminal device, and a network device. The wireless communication method includes: determining, by a terminal device, a start time of a time window for random access according to a first Round Trip Time (RTT) offset value, or determining, by the terminal device, the start time of the time window for random access according to a first RTT offset value group. Each RTT offset value in the first RTT offset value group corresponds to an RTT interval, respectively.

The present application relates to devices and components including apparatus, systems, and methods for ephemeris signaling in wireless networks.

A request for registration by a User Equipment (UE) to a cellular network is handled. The geographical coverage of the cellular network is divided into a plurality of tracking areas, each tracking area having a respective identifier. A registration request message is communicated from the UE to the cellular network via an access node. Where the registration request is rejected, a registration rejection message is communicated in response. The registration request message and/or the registration rejection message includes the identifier for each of one or more tracking areas to which the respective message applies.

Techniques are disclosed for managing uplink data transmission associated with user equipment during authentication/authorization of the user equipment when establishing a data network connection through a communication network.

Aspects of the subject disclosure may include, for example, an aerial base station determining operating frequencies of terrestrial base stations, and taking one or more actions to reduce the potential for interference between the aerial base station and the terrestrial base stations. Actions taken by the aerial base station may include changing frequency, changing altitude, changing location, and changing transmit power. Other embodiments are disclosed.

Provided is a navigation system for operating a navigation system, which navigation system includes a first sub navigation system placed at an aeroplane and a second stationary sub system, which first sub navigation system includes a plurality of radio receivers, which radio receivers are configured to receive signal from a plurality of navigation satellites, which navigation system includes at least one processor, which processor is configured to perform calculation of the actual position data, which navigation system includes a radio transmitter, which radio transmitter is configured to transmit position data to communication satellites. The communication satellites can include radio transmitters for transmitting position data to a ground based receiver, which second sub system includes at least one server. Hereby can position data in that way the position of that aeroplane will be calculated and the actual position data and actual time will be stored in the server.

A method, apparatus, and computer program product provide for crowdsourcing data from a plurality of aircraft systems to determine cloud ceiling information. In the context of a method, the method receives a set of sensor data from a first aircraft system captured during a first event. The method determines, based on the set of sensor data, a cloud ceiling value for a location and a time at which the first set of sensor data was captured. The method also stores the cloud ceiling value in association with a landing region and causes transmission of the cloud ceiling value to one or more additional aircraft systems.

Provided is a satellite network communication method. The method includes: establishing for a user equipment a satellite network communication channel between a proxy service apparatus on an end station side and a proxy service apparatus on a master station side; intercepting a resource access request sent by the UE; and when a target resource corresponding to the resource access request does not locally exist, acquiring the target resource through the satellite network communication channel and sending the target resource to the user equipment. Further provided are a proxy service apparatus and a gateway.
