Abstract: A user equipment and a circuit-switched fallback method thereof are provided. An initial base station sends a radio resource control connection release message containing the redirection frequency list to the UE. The redirection frequency list includes at least one redirection frequency. The UE determines a priority of the at least one redirection frequency according to a current registered LAI, a learning database and a piece of signal reference information of the redirection frequency list. Accordingly, the UE executes a circuit switch fallback procedure according to the priority of the at least one redirection frequency.

Abstract: Aspects of the disclosure provide a method for setting up a call for a user equipment. The method includes receiving, by the user equipment, a measurement configuration message that specifies a set of measurement events corresponding to poor signal quality between the user equipment and a packet-switched network, and sending, by the user equipment, a measurement report when one of the set of measurement events occurs while performing a first call setup process for setting up the call using the packet-switched network. The method also includes terminating the first call setup process after sending the measurement report that indicates poor signal quality between the user equipment and the packet-switched network, and sending, by the user equipment, a service request to begin a second call setup process for setting up the call for the user equipment using a circuit-switched network after terminating the first call setup process.

Abstract: Various solutions for improving data throughput with respect to a multiple subscriber identity module (SIM) user equipment (UE) in mobile communications are described. The UE may perform data transmission associated with a first SIM. The UE may determine whether to suspend a recovery procedure associated with a second SIM according to a condition. The UE may suspend the recovery procedure associated with the second SIM in an event that the condition is satisfied. The UE may further resume the recovery procedure associated with the second SIM when the first SIM enters an idle mode.

Abstract: A mobile communication device including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller operates in a connected mode with a connection to the service network, and determines whether there is no active data traffic in a first period of time when operating in the connected mode. In response to there being no active data traffic in the first period of time, the controller performs a local release of the connection or sends a measurement report to trigger the service network to release the connection.

Abstract: To facilitate LWA PDCP setting/scheduling, a method of providing dynamic PDCP status report polling is proposed. To enhance scheduling efficiency, the transmitter (can be eNB from DL or UE for UL) can dynamically poll PDCP status report for LWA behavior. The polling can be done by a standalone PDCP control PDU or use reserved bit in PDCP data PDU. The triggering condition for PDCP status polling includes: PDCP without poll time exceeds a first threshold, PDCP without poll bytes exceeds a second threshold, PDCP without poll PDU numbers exceeds a third threshold, a data buffer is empty, and when LWA is deactivated.

Abstract translation: 为了方便LWA PDCP设置/调度，提出了一种提供动态PDCP状态报告轮询的方法。 为了提高调度效率，发射机（可以是来自DL的UE或用于UL的eNB）可以动态地轮询PDCP状态报告以用于LWA行为。 轮询可以由独立的PDCP控制PDU完成，也可以在PDCP数据PDU中使用保留位。 PDCP状态轮询的触发条件包括：没有轮询时间的PDCP超过第一个阈值，没有轮询字节的PDCP超过第二个阈值，没有轮询PDU号码的PDCP超过第三个阈值，数据缓冲区为空，当LWA被禁用时。
