Abstract:
1. A wireless terminal for accessing a network through a first access point and a second access point, comprising: a memory; at least one processor; a transmission unit operable to transmit and receive signals from the first access point and the second access point; one or more programs that are stored in the memory and are executed by the at least one processor, the one or more programs comprising: a monitor module operable to monitor a status of the transmission unit; a decoding module operable to decode the signals received from the first access point and the second access point to get a correct probability of each bit of the signals; a calculation module operable to calculate mean values of the each bit of the signals received from the first access point and the second access point, and calculate a variance value of the each bit of the signals received from the second access point; a determination module operable to determine whether a difference in the mean values of the second access point and the first access point exceeds a product of the variance value of the second access point and a roaming weight of the first access point, wherein the roaming weight of the first access point is a constant; and a switch module operable to switch the wireless terminal from the first access point to the second access point to access the network.
