Patent ID: 7421703

Claim:
A method for processing a message of an agent, comprising the steps of: managing a state of an agent based on whether the agent is in a memory and whether there is a message, by determining a priority level of the agent based on the message inserted into the agent; assigning a thread to the agent if the agent is in the memory and assigning the thread to the agent after calling the agent to the memory if the agent is not in the memory, on condition that the agent having a highest priority level has been detected; and repeating message processing until a predetermined criterion is satisfied, in relation to the agent to which the thread has been assigned, wherein the step of assigning a thread further comprises: assigning a thread to an agent existing in the memory preferentially over an agent not existing in the memory, on condition that an agent having the highest priority level is not detected; wherein in the step of assigning a thread, if agents are in the same state in terms of whether the agents exist in the memory, a message having a higher priority level is preferentially assigned a thread; wherein selectively the predetermined criterion is that a predetermined number of messages have been processed for one agent, or that messages having priority levels other than a lowest priority level have been processed; and wherein the step of managing a state of an agent further comprises: the step of determining, after the message has been processed, the priority level of the agent based on a most prioritized message of remaining messages.
