The invention provides a hot switching method, a wireless LAN can include: step 102, real-time detection terminal has access to a focus in the continuous signal strength of a plurality of unit time; step 104, comparing access hot spots in the continuous signal strength of a plurality of unit time, according to the access of hot spots in the continuous signal intensity of multiple units time is continued to weaken, confirm whether the terminal is far away from the hot spot has access; step 106, confirm the terminal is far away from the hot has access, the threshold current signal strength has been hot access with preset for comparison; step 108, in the current hot spot has access to the signal strength below a preset threshold from the terminal to scan, hot, hot selection signal intensity is higher than the threshold for access to the terminal. The invention also provides a terminal. The invention can automatically select the hot spot for the terminal automatically according to the signal intensity, and can be used for accessing the wireless local area network.
【技术实现步骤摘要】
【技术保护点】
一种无线局域网的热点切换方法，其特征在于，包括： 步骤１０２，实时检测终端已接入的热点在连续多个单位时间的信号强度； 步骤１０４，比较所述接入的热点在所述连续多个单位时间的信号强度，根据所述已接入的热点在所述连续多个单位时间的信号强度是否持续减弱，确认所述终端是否正在远离所述已接入的热点； 步骤１０６，在确认所述终端正在远离所述已接入的热点时，将所述已接入的热点的当前信号强度与预设的阈值进行比较； 步骤１０８，在所述已接入的热点的当前信号强度低于所述预设的阈值时，从所述终端扫描到的热点中，选择信号强度高于所述阈值的热点为所述终端重新接入。
