Samsung patents method for dual-SIM phones to manage network connections
This patent describes a way for phones with multiple SIM cards to coordinate when they check in with different cellular networks. It prevents the phone from trying to send data or report network quality during specific "switching gaps" reserved for other tasks, such as moving between networks.
In the filing’s own words
Embodiments herein provide a method for coordinated switching gap operations by a UE ( 100) comprising a plurality of SIMs ( 150) in a wireless network ( 1000). The method includes detecting that at least one of a BSR triggering, grant for uplink transmission, and measurement report and CSI reporting time for a first network operator apparatus ( 200 a) lies in between one of the switching gap start and stop time, a switching gap duration, and a number of repetitions of the switching gap. In an embodiment, the method includes preventing a triggering of the BSR to the first network operator apparatus ( 200 a). In another embodiment, the method includes reporting a new BSR report to the first network operator apparatus ( 200 a) to indicate no buffered data. In another embodiment, the method includes abandoning or discarding at least one of the measurement report or the CSI reporting from the UE ( 100).
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE) comprising a multiple universal subscriber identity module (MUSIM) in a wireless communication system, the method comprising: initiating transmission of a UE assistance information message including a preference to leave a radio resource control (RRC) connected state of a first network associated with a first universal subscriber identity module (USIM), wherein the preference indicates an RRC idle state or an RRC inactive state; starting a timer after initiating transmission of the UE assistance information message including the preference to leave the RRC connected state of the first network; and upon an expiry of the timer, entering the RRC idle state or the RRC inactive state of the first network.
