ABSTRACT:
A wireless communication terminal roaming from a current access point (AP) to a destination AP within a plurality of APs includes various functional modules. The wireless communication terminal detects a current service quality parameter of each of the plurality of APs, a roaming frequency, and a packet retransmission rate of the wireless communication terminal in a predetermined detection period. Furthermore, the wireless communication terminal calculates a value of an RQI according to the current service quality parameter of each of the plurality of APs, the roaming frequency, and the packet retransmission rate of the wireless communication terminal, and regulates a roaming threshold of the current AP according to the value of the RQI and determines the destination AP that has satisfied a roaming condition corresponding to the value of the RQI.
