A fast handover method for a mobile terminal adopting IPv6 in a wireless local area system including the mobile terminal and a plurality of wireless access points, APs, of which one is a serving AP currently communicating with the mobile terminal and others represent neighbor APs of the mobile terminal, wherein the plurality of APs communicate with the mobile terminal over a radio channel, the method comprising: receiving a beacon frame signal from the serving AP and the neighbor APs of the mobile terminal at certain intervals, characterized in that the method further comprises: processing a parameter contained in each beacon frame signal to determine a state of each of the neighbor APs based on the beacon frame signal received from each of the neighbor APs, wherein the parameter is a signal-to-noise ratio, SNR; comparing the parameter of each beacon frame signal with predefined thresholds, prioritizing the neighbor APs according to a result of the comparison, and storing the prioritizing result in a neighbor AP list; judging a timing of each beacon frame signal for signalling a neighbour AP list manager to delete a neighbor AP from the list if a beacon frame signal is not received from the neighbor AP within a certain time period; selecting an AP for the handover based on the prioritization result in the neighbor AP list; analyzing a radio channel state of the serving AP; and commencing a handover of communications to an undeleted highly prioritized neighbor AP if the parameter detected from the signal received from the serving AP falls below a predefined threshold (THR_2). receiving a beacon frame signal from the serving AP and the neighbor APs of the mobile terminal at certain intervals, characterized in that the method further comprises: processing a parameter contained in each beacon frame signal to determine a state of each of the neighbor APs based on the beacon frame signal received from each of the neighbor APs, wherein the parameter is a signal-to-noise ratio, SNR; comparing the parameter of each beacon frame signal with predefined thresholds, prioritizing the neighbor APs according to a result of the comparison, and storing the prioritizing result in a neighbor AP list; judging a timing of each beacon frame signal for signalling a neighbour AP list manager to delete a neighbor AP from the list if a beacon frame signal is not received from the neighbor AP within a certain time period; selecting an AP for the handover based on the prioritization result in the neighbor AP list; analyzing a radio channel state of the serving AP; and commencing a handover of communications to an undeleted highly prioritized neighbor AP if the parameter detected from the signal received from the serving AP falls below a predefined threshold (THR_2). processing a parameter contained in each beacon frame signal to determine a state of each of the neighbor APs based on the beacon frame signal received from each of the neighbor APs, wherein the parameter is a signal-to-noise ratio, SNR; comparing the parameter of each beacon frame signal with predefined thresholds, prioritizing the neighbor APs according to a result of the comparison, and storing the prioritizing result in a neighbor AP list; judging a timing of each beacon frame signal for signalling a neighbour AP list manager to delete a neighbor AP from the list if a beacon frame signal is not received from the neighbor AP within a certain time period; selecting an AP for the handover based on the prioritization result in the neighbor AP list; analyzing a radio channel state of the serving AP; and commencing a handover of communications to an undeleted highly prioritized neighbor AP if the parameter detected from the signal received from the serving AP falls below a predefined threshold (THR_2).
