Abstract

A communication device includes a processing unit (PROC), a volatile memory (VMEM), a non-volatile storage medium (NMEM) having stored thereon a first set of instructions and a second set of instructions, and a communication unit (COMM) being coupled to the processing unit (PROC). During a transition from a standby mode of operation to an idle mode of operation, the first set of instructions is loaded into the volatile memory (VMEM) enabling the processing unit (PROC) to execute the loaded first set of instructions. During a transition from the idle mode of operation to an active mode of operation, the second set of instructions is additionally loaded into the volatile memory (VMEM) enabling the processing unit (PROC) to execute instructions from the loaded first set of instructions and the loaded second set of instructions. The processing unit is configured, in the idle mode of operation (PROC), to interact with the communication unit (COMM) for detecting, using instructions from the first set of instructions, whether a triggering message is received via the communication unit (COMM), and to initiate the transition from the idle mode of operation to the active mode of operation in response to the detection of the triggering message.

a communication unit (COMM) being coupled to the PROC;
wherein the communication device is configured
to selectively be operated in a standby mode of operation, in an idle mode of operation and in an active mode of operation;
during a transition from the standby mode of operation to the idle mode of operation, to load the first set of instructions into the VMEM enabling the PROC to execute the loaded first set of instructions;
during a transition from the idle mode of operation to the active mode of operation, to additionally load the second set of instructions into the VMEM enabling the PROC to execute instructions from the loaded first set of instructions and the loaded second set of instructions;
wherein the PROC is configured, in the idle mode of operation, to interact with the COMM for detecting, using instructions from the first set of instructions, whether a triggering message is received via the COMM, and to initiate the transition from the idle mode of operation to the active mode of operation in response to the detection of the triggering message.
