Samsung patents cell switching method for satellite store-and-forward mode
Samsung describes a method for mobile devices to check if a satellite connection can send data immediately. If the satellite link is busy or unavailable, the device automatically searches for a different network cell that can handle the data properly.
In the filing’s own words
A method for PLMN/cell selection or reselection based on the feeder link availability is provided. A system and a method for managing a Public Land Mobile Network (PLMN) selection, cell selection and/or reselection for a Store and Forward (S&F) mode in a wireless network system is provided. The method comprises the UE determining that a first cell supports S&F mode and a feeder link is unavailable. The UE performs a PLMN selection, a cell selection, and/or a cell reselection in the wireless network system to search for a second cell, wherein the feeder link is available on the second cell and a network apparatus associated with the UE is able to provide normal services to the UE.
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE) in a wireless network system, comprising: determining whether a feeder link is unavailable on a first cell supporting a store & forward (S&F) mode; and based on a determination that the feeder link is unavailable on the first cell, performing at least one of a public land mobile network (PLMN) selection, a cell selection, or a cell reselection in the wireless network system to search for a second cell capable of providing normal service to the UE.
