US 2025/0055559 A1 · STORE AND FORWARD SATELLITE ACCESS WITH DISCONTINUOUS FEEDER LINKS

Abstract

Techniques are described to enable a user equipment (UE) to communicate with remote endpoints by accessing a space vehicle (SV) in a store and forward (S&F) mode when the SV does not have a feeder link to a ground based network. The SV can include on board radio access network and core network capability which can enable the UE to communicate with an on board proxy for the remote endpoints. The proxy stores mobile originated (MO) voice and data sent by the UE and returns mobile terminated (MT) voice and data sent by the remote endpoints. When the SV has a feeder link, the proxy forwards MO data to a second proxy in an S&F center for forwarding to the remote endpoints and can receive MT data from the second proxy for the UE. UEs can access SVs without restriction and are registered only while accessing an SV.

Dependent claims

An apparatus for wireless communication performed by a user equipment (UE), the apparatus comprising:

at least one memory;
and
at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the UE to:
access a space vehicle (SV) using a service link at a time that the SV does not have a feeder link to a ground based network and the UE is not registered with the SV;
register with the SV;
send mobile originated (MO) data intended for at least one remote endpoint to the SV for storage at the SV until the SV has the feeder link to the ground based network to forward the MO data to the at least one remote endpoint via the ground based network;
de-register from the SV;
and
cease to access the SV.

6 more elements

An apparatus for wireless communication performed by a space vehicle (SV), the apparatus comprising:

at least one memory;
and
at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the SV to:
provide wireless access to a user equipment (UE) via a service link, wherein the SV does not have a feeder link to a ground based network, wherein the UE is not registered with the SV;
register the UE;
receive mobile originated (MO) data from the UE, the MO data intended for at least one remote endpoint;
store the MO data;
de-register the UE;
cease to provide the wireless access to the UE;
obtain the feeder link to the ground based network;
and
forward the MO data to the at least one remote endpoint via the ground based network.

9 more elements

An apparatus for wireless communication performed by a server, the apparatus comprising:

at least one memory;
and
at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the server to:
receive mobile originated (MO) data from a space vehicle (SV) with a feeder link to the server, the MO data intended for at least one remote endpoint, wherein the MO data is sent by a user equipment (UE) to the SV using a service link at a time when the SV did not have the feeder link with the server, wherein the UE is registered with the SV and later de-registered from the SV without assistance from the server, and
forward the MO data to the at least one remote endpoint via a network.
