Patent ID: 8060036

Claim:
A wireless terminal device for communicating with one of a plurality of base stations, comprising: a detector for generating at least one probe request to detect at least one of a plurality of channels communicating the wireless terminal device with the plurality of base stations; a transceiver for transferring the at least one probe request to and receiving signals in addition to probe responses of the at least one probe request from the plurality of base stations, the received signals comprising data packets and beacons; an analyzer for analyzing the received signals to obtain workload indices and received signal strength indications (RSSIs) of the plurality of base stations at the wireless terminal device as analysis result, and analyzing address fields in the data packets to retrieve the number of terminal devices connected to respective one of the plurality of base stations as the workload indices of the plurality of base stations; an execution module configured for generating a comprehensive index for each of the plurality of base stations according to the analysis result, thus generating comprehensive indices of the plurality of base stations, and for finding a best comprehensive index from the generated comprehensive indices of the plurality of base stations; and a connection module configured for establishing wireless communication between the wireless terminal device and the base station corresponding to the best comprehensive index.
