Abstract
A communication device comprises a single radio resource unit that is shared by a plurality of virtual modems (VMs), each uniquely associated with a single one of a plurality of SIM cards. Traffic related to the SIM cards are concurrently handled utilizing corresponding VMs. Available radio resource in the single radio resource unit are shared by the VMs based on corresponding VM states, namely, an active state, an idle state and a suspended state. VMs in an idle state concurrently monitor paging events and concurrently perform idle mode procedures such as location updating. VMs not related to an intended traffic are suspended. A VM related to the intended traffic is transitioned from an idle state to an active state to enable the communication for the intended traffic. Once the communication is complete, the suspended VMs are resumed to continue idle mode activities.
