Method and system for task mapping based on corresponding virtual modem identifiers in an operating system for virtual modems within a multi-SIM multi-standby communication device

A system for communication, the system comprising:

• one or more processors and/or circuits for use in a multiple-subscriber identity module (multi-SIM) multi-standby communication device comprising an operating system (OS) and a radio resource unit that is shared by a plurality of virtual modems, said one or more processors and/or circuits being configured to:
• embed corresponding virtual modem identifiers in static variables, and global variables;
• map tasks for said plurality of virtual modems to OS resource spaces of said OS based on said embedded corresponding virtual modem identifiers, said static variables and said global variables being utilized by said OS to access OS resources in said OS resource spaces;
• determine a task priority for one or more of said mapped tasks of said plurality of virtual modems based on corresponding virtual modem environment information, wherein said virtual modem environment information comprises information on a virtual modem state or task context and
• run said mapped tasks on said OS utilizing said OS resources in said OS resource spaces based on said determined task priority.

A communication device, comprising:

• a radio resource unit configured to communicate with a communication network utilizing a virtual modem;
• and
• a processor communicatively coupled to said radio resource unit, the processor being configured to:
• embed a corresponding virtual modem identifier in a global variable;
• map a task of said virtual modem to an operating system resource space of an operating system based on said corresponding virtual modem identifier, said global variable being utilized by said operating system to access said operating system resource;
• determine a task priority for said mapped task of said virtual modem based on corresponding virtual modem environment information wherein said virtual modem environment information comprises information on a virtual modem state or task context;
• and
• run said mapped task on said operating system utilizing said operating system resource in said operating resource space based on said determined task priority.
