Abstract: Solutions are proposed to facilitate the support of 3GPP PS_Data_Off feature. The PS_Data_Off feature prevents transport via 3GPP access of all IP packets except those related to 3GPP PS_Data_Off Exempt Services. In one example, signaling storms due to frequent PS_Data_Off reconfiguration are prevented. In another example, for multi-SIM devices and for devices that supporting WiFi access, UE reconfigures the PS_Data_Off feature upon a triggering condition is satisfied. In yet another example, upon status change of PS_Data_Off feature, UE initiates RAT change to improve performance, to reduce power consumption and cost, and to maintain service continuity. Furthermore, new AT commands and parameters are introduced to enable the PS_Data_Off feature.

Abstract: A mobile communication device including a Radio Frequency (RF) device and a baseband processor is provided. The RF device performs wireless transmission and reception to and from one or more cells. The baseband processor uses a first subscriber identity to establish a connection with a serving cell via the RF device to perform a first communication procedure, and in response to completing the first communication procedure or the first communication procedure being interrupted by a second communication procedure associated with a second subscriber identity, uses the first subscriber identity to send a measurement report to the serving cell via the RF device. In particular, the measurement report indicates a reported signal quality of the serving cell is poor enough to release the connection.
