Samsung patents faster satellite connection checks for phones
Samsung describes a method for phones to detect when their connection to a satellite network is failing. The system uses specific timers and timing checks to determine if the link has dropped, helping the device react quickly to signal issues.
In the filing’s own words
Methods and apparatuses for an enhanced radio link failure (RLF) detection in a non-terrestrial network (NTN) are provided. A method of operating a user equipment (UE) includes identifying a value of a timer and a time value and determining that the timer has started upon detection of a radio link problem. The radio link problem is based on a first counter. The method further includes determining that a current time is passed the time value and detecting a radio link failure based on a determination that the timer has started and the current time is passed the time value.
What exactly they claim (claim 1)
1. A user equipment (UE) in a wireless communication system, the UE comprising: at least one processor including processing circuitry; and memory storing instructions, wherein the instructions, when executed by the at least one processor individually or collectively, cause the UE to: receive, from a base station (BS), system information including at least one handover (HO) common configuration; receive, from the BS, a HO command including a HO configuration; in case that the HO configuration is an optional field, identify whether an indication configured in the HO configuration indicates that the HO configuration is derived from the HO common configuration; in case that the indication indicates that the HO configuration is derived from the HO common configuration, identify whether a current time meets a timing criterion; and in case that the current time meets the timing criterion, derive the HO configuration from the HO common configuration.
