A high-altitude platform (HAP) node provides communication service during an emergency. The HAP node uses a first network to provide communication services for handling calls initiated by at least one user equipment (UE). The HAP node detects that an emergency disruption has occurred that prevents the use of the first network. In response to detecting the occurrence of the emergency disruption, a mobile terminal (MT) in the HAP node searches for a second network able to accept emergency calls. The HAP node determines whether the second network will handle all calls initiated by the at least one UE or only emergency calls generated by the at least one UE. The HAP node handles the calls based on the determining and through the use of the second network.

This disclosure relates generally to wireless communications and, more particularly, to systems and methods for maintaining signal and data connections from a mobile base station portion relative to a fixed network portion. In one embodiment, a method performed by a communication node gateway, includes: receiving a signal from a mobile communication node portion at a first dynamic port during a first duration of time; directing the signal from the first dynamic port to a static port associated with transport network layer information during the first duration of time; receiving the signal at a second dynamic port during a second duration of time after the first duration of time; and directing the signal from the second dynamic port to the static port during the second duration of time by using the transport network layer information.

A cellular system and method to provide voice and data services to a user terminal are disclosed. The cellular system includes a cellular base station; a satellite backhaul including a first satellite link and a second satellite link; and a traffic classifier to classify traffic from the cellular base station as voice traffic for transportation via the first satellite link and as data traffic for transportation via the second satellite link.

A multi-mode communication adapter system comprising: a mobile Earth station including: a flat panel antenna configured to receive a down-link satellite packet, wherein the flat panel antenna includes a waveguide interposer, a satellite Rx/Tx, coupled to the flat panel antenna, configured to decode the down-link satellite packet, a storage device, coupled to the satellite Rx/Tx, configured to store satellite data from the down-link satellite packet, a first interface module, coupled to the storage device, configured to encode and transfer the satellite data as a cellular communication packet, a second interface module, coupled to the storage device, configured to encode and transfer the satellite data as a WiFi packet, and a multi-band transceiver, coupled to the first interface module and the second interface module, configured to concurrently transfer the cellular communication packet and the WiFi packet without accessing a local infrastructure; and a protective cover encloses the mobile Earth station.

Systems and methods for obtaining data for Dynamic Frequency Selection (DFS) events caused by interfering signals, such as radar signals, in mobile WiFi wireless communication networks on airplanes. The systems and methods utilize wireless access points (WAPs) on in-flight entertainment systems on airplanes to detect DFS events, and obtain DFS event data. The DFS event data is transmitted to a ground system which is configured to utilize the DFS event data to generate DFS messages which allow a WAP on another airplane to avoid the interfering signals that caused the DFS event. The ground system transmits the DFS messages to other airplanes which use the information in the DFS message to configure a WAP to avoid DFS events. The ground system may also be configured to analyze and generate a 3D DFS map which can be used to generate radio channel plans to avoid DFS events.

Realized is a communication terminal which, in a case where a status of communication with a low-earth-orbit satellite becomes poor, notifies a user that the status of the communication with the low-earth-orbit satellite is poor. A communication terminal includes: a determining section which determines whether or not an index satisfies a given condition, the index being calculated based on at least one of communication status information indicative of a status of communication between the communication terminal and a satellite, a status of decoding of a signal received from the satellite, and a status of readiness of voice communication based on the signal received from the satellite; and a notification control section which, in a case where the determining section determines that the index satisfies the given condition, controls a notification to be sent to a user of the communication terminal, the notification indicating that the index satisfies the given condition.

Systems and methods for detecting and reducing signal interference affecting wireless communication with a mobile vehicle includes generating an interference signature based on a correlation multiple signal-quality characteristics of a desired target-signal that is received at an antenna assembly attached to the mobile vehicle, and adjusting the orientation of the antenna assembly based on a change or degradation in the interference signature to thereby improve wireless communication with the vehicle.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam configurations and parameters for non-terrestrial networks. In some implementations, a UE may detect a synchronization signal block (SSB) transmitted by a satellite via a first beam. Aspects of the present disclosure recognize that each beam may be identified by a unique SSB index based at least in part on a time or frequency on which the SSB is received. Thus, the SSB may be identified based on a frequency-domain SSB index or a time-domain SSB index. The UE may further determine one or more wireless communication parameters associated with the first beam. The UE may generate a mapping between the SSB and the wireless communication parameters associated with the first beam, and thereafter communicate with the satellite using the mapping.
