Abstract: A method performed by a multi-subscriber identity module (MUSIM) user equipment (UE) for continuing operation of the MUSIM UE in a first mode, the MUSIM UE including a first SIM and a second SIM, and the method including transmitting, by the MUSIM UE, an uplink signalling message in response to determining a trigger condition has been satisfied, the uplink signalling message including one of compatible band information for the first SIM and the SIM, or one or more other stacks serving band information associated with the second SIM, receiving, by the MUSIM UE from a network, a radio resource control (RRC) reconfiguration signalling message for performing at least one activity at the first SIM in response to the transmitting the uplink signalling message, and performing, by the MUSIM UE, the at least one activity based on the RRC reconfiguration signalling message.

Abstract: A method and user equipment are provided. The method includes initiating a circuit-switched (CS) connection establishment procedure by transmitting a connection management (CM) service request message to a core network (CN). Mobility management (MM) connection establishment is aborted in response to failing to receive a CM service acceptance message within a time period. In response to subsequently receiving a CM service acceptance message after aborting the MM connection establishment, a circuit-switched (CS) signaling connection release action is performed.
