Samsung patents satellite data delivery timing for store-and-forward service

Samsung describes a method for mobile devices to manage satellite communication using a store-and-forward service. The device requests an estimated delivery time from a network node on the satellite, then uses that time to adjust its internal timers and communication procedures.

Why it mattersThis could improve how phones handle data sent via satellites by ensuring the device knows exactly when to expect a response, preventing unnecessary retransmissions.

In the filing’s own words

Methods and systems for managing satellite communication using a store and forward (S&F) service with at least one network node onboarding a satellite are disclosed. The method includes determining, by a User Equipment (UE), that a network supports the S&F service; determining, by the UE, at least one new value of a timer and provide the estimated delivery time to upper layers of the UE, to use the at least one new value of the timer by an application layer based on at least one estimated delivery time received from a core network node ( 600; and initiating, by the UE, at least one Non-Access Stratum (NAS) procedure with the network based on the determined at least one new value of the timer.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) for managing satellite communication using a store and forward (S&F) service with a core network node onboarding a satellite, the method comprising: transmitting a request message to the core network node; and receiving an accept message as a response of the request message from the core network node, the accept message including information on an estimated delivery time for data to reach a ground station from the UE; and performing a communication based on the estimated delivery time.
