Method and system for dynamically selecting and configuring virtual modems (vms) based on performance metrics in a multi-sim multi-standby communication device

Abstract

A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single radio resource unit shared by a plurality of virtual modems (VMs), each uniquely associated with a single one of a plurality of SIM cards. The access to radio resources in the single radio resource unit is controlled via a virtual modem controller (VMC). The VMC collects performance metrics such as requested service type and signal quality associated with each of the VMs. A VM is selected based on the collected performance metrics to perform a requested service. A serving VM is switched among the VMs based on the collected performance metrics. VM capabilities are dynamically configured based on the collected performance metrics. According to the collected performance metrics such as associated navigation information and requested service type, one or more VMs may be turned on or off, and certain VM capabilities may be enabled or disabled to save resources.
