Abstract:
1. A method for a user equipment (UE) to access a wireless network, wherein the wireless network comprises a plurality of access points and the UE is in communication with a serving access point, the method comprising: measuring a Doppler frequency shift of a signal sent by each of the plurality of access points to obtain a relative speed between the UE and the each of the plurality of access points according to the Doppler frequency shift; measuring a signal intensity of each of the plurality of access points; when the relative speed between the UE and the serving access point is greater than a threshold speed, determining whether there is at least one non-serving access point the relative speed between which and the UE is smaller than or equal to the threshold speed; and if there are one or more non-serving access points the relative speed between which and the UE is smaller than or equal to the threshold speed, and one non-serving access point having a maximum signal intensity is selected among the one or more non-serving access points for the serving access point to hand over the UE to, establishing a communication connection between the UE and the selected non-serving access point.
