Mobile terminal device for handover in WLAN and method thereof

摘要

A handover method of a mobile terminal device in a wireless local area network (WLAN) includes a mobile terminal device and at least two wireless access points (APs) which communicate with the mobile terminal device using particular radio resources. The mobile terminal device communicates with a wireless AP via a first radio resource, and receives signals from wireless APs via a second radio resource. The mobile terminal device arranges and stores the signals received from the wireless APs in a certain order of size. The mobile terminal device determines an AP for the handover by sequentially searching the stored APs when intensity of the signal received via the first radio resource is smaller than a predetermined value.
