Patent ID: 7369565

Claim:
A wireless communication system, comprising: a queue information search unit for searching a queue-status information provided to a data in a packet unit; a communication priority decision unit for deciding a communication priority of a plurality of external devices based on the queue-status information as searched, giving a higher priority to an external device having a greatest number of packets in queues; a communication initiation unit for initiating a communication with the plurality of external devices according to the communication priority as decided; a counter for counting a number of times that the communication is initiated for each of the plurality of external devices; and a comparator for comparing a first counter value of a first external device that corresponds to a transmitted data with a second counter value of a second external device that has a maximum counter value, wherein when a counter value difference between the first external device and the second external device is smaller than a predetermined threshold, the communication initiation unit initiates communication with the third external device which has a highest communication priority.
