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.
