A method of exchanging data involving at least one apparatus (APP) and user terminals, or UTs. The method comprises: receiving measurements data from the UTs, choosing at least one precoding subset associated to groups of antennas (GANT.sub.1, . . . , GANT.sub.n) defining beam areas (BA) having a considered color, each precoding subset comprising at most one UT from each of the considered beam areas, each precoding subset being chosen by selecting one or more UT each located in a different beam area among the considered beam areas as a function of at least respective angular positions of the UTs within the corresponding beam area and determined based on the measurements data, generating at least one signal constructed as a function of the data destined to the UTs of the precoding subset or coming from the UTs of the precoding subset to transfer said data to the UTs or receive said data from the UTs using the groups of antennas associated to said at least one precoding subset.

The disclosure relates in some aspects to forbidden area procedures and connection release management for a user terminal (UT). Forbidden area-related procedures include, for example, using a special paging area code (PAC) in conjunction with a forbidden area, defining a location reporting threshold for a UT based on the proximity of the UT to a forbidden area, or using a default paging area code if a service restriction for a UT has ended. Connection release management includes, for example, a UT sending a request to cause the release of a Radio Connection that the UT no longer needs, or a UT sending a Location Indication (e.g., including a flag requesting release of a connection) to release the connection used for location reporting when a UT is done sending the location information and is going to go back to idle mode.

A system and method for networked geofencing includes identifying restricted areas in a service region, and defining a protective zone surrounding the restricted areas. A service availability map containing the protective zones is generated and broadcast within the service region. The positions of terminals on the service availability map are detected relative to the protective zones. Terminals inside the protective zones establish communication using a first frequency range, and terminals outside of the protective zones establish communication using either the first frequency range or a second frequency range.

A base station is provided. The base station includes a base band unit and one or more remote radio heads, a satellite-based content delivery network (S-CDN) device, and a local serving gateway (LS-GW). The base station unit and the one or more remote radio heads wirelessly communicate with a user equipment. The S-CDN device receives and caches content from a satellite-based content delivery network. The LS-GW is connected to the S-CDN device and the base band unit. The LS-GW receives a request for content from the user equipment, determines whether the content is already stored in the S-CDN device, and when the content is already stored in the S-CDN device, delivers the content to the user equipment from the S-CDN device.

A wireless communication method for use in a wireless terminal is disclosed. The method comprises receiving, from a wireless network node, a satellite selection policy, and applying the satellite selection policy on a satellite selection.

In one embodiment of the present disclosure, a device for detecting a zone of communication between a user terminal and a satellite constellation including a plurality of satellites in non-geosynchronous (non-GEO) orbit includes one or more processors and memory. The memory stores instructions that, as a result of being executed by the one or more processors, cause the device to: determine a location of the device, wherein the location corresponds to a field of regard for detecting the zone of communication, and wherein the field of regard corresponds to an antenna aperture of the phased array antenna; evaluate a level of communication between the phased array antenna and the satellite constellation associated with the field of regard; and output, to a user of the device, an indication of the level of communication between the phased array antenna and the satellite constellation associated with the field of regard.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain, at an access stratum (AS) layer, an indication of an inter-satellite link (ISL) activation that is to take place at an activation time. The wireless communication device may receive communications. The wireless communication device may buffer the communications in a buffer at the AS layer. The wireless communication device may release the communications from the buffer to an upper protocol layer at a rate of release that is to change between a transition start time and the activation time. Numerous other aspects are described.

Measures for managing satellite bearer resources of a satellite telecommunications network. A corpus of data based on historical satellite bearer resource allocations is maintained. A machine learning agent is trained with the corpus to determine a plurality of weights for use in directing satellite bearer resource management in the satellite telecommunications network. A satellite bearer resource allocation request is received. A set of features is extracted from a current environment of the satellite telecommunications network. The set of features defines currently allocated satellite bearer resources. On the basis of the determined plurality of weights and the set of features, satellite bearer resources of the satellite telecommunications network are managed to satisfy the request.

The present disclosure provides a paging method, a positioning information sending method, a core network node and a base station, and relates to the technical field of communication. The paging method is applied to the core network node in a satellite Internet communication system and comprises the following steps: acquiring the setting mode of the tracking area TA in the satellite Internet communication system; determining the base station for paging the terminal according to the setting mode; and sending a paging message to the base station; wherein the setting mode comprises one of the following setting mode: dividing the satellite Internet communication system one TA; setting at least two fixed TAs; and setting at least two non-fixed TAs.

This present disclosure describes techniques for relaying user plane data from a core network to a recipient device via a terrestrial core network. An orchestration controller is described that is configured to receive an indication that a terrestrial core network has received user plane data for transmission to a recipient device, detect a constellation of Low Earth Orbit (LEO) satellites to transmit the user plane data to the recipient device, select at least a first LEO satellite to receive the user plane data, and transmit the user plane data to the first LEO satellite.
