Abstract:
Methods and devices for scheduling data packet transmissions on a multi-subscriber identity module (SIM) wireless communication device having at least a first SIM and a virtual SIM (VSIM) application associated with a shared radio frequency (RF) resource may include detecting registration of a SIM profile for the VSIM application, in which the VSIM application is provisioned to operate as a VSIM, and determining whether a VSIM management procedure is required for the VSIM. When a VSIM management procedure is required for the VSIM, the wireless communication device may tag data packets associated with the required VSIM management procedure, select a prioritization policy for data packet transmissions on the RF resource, and apply the selected prioritization policy within a transmission queue on the RF resource.
