软切换区： 定义软切换区，确保移动终端在进入新的切换区时能够及时地与新的基站建立连接。
Evolution-Data Optimized, generally known as EV-DO, is usually a telecommunications standard for wireless transmission of data as a result of radio alerts, largely Utilized in broadband Online access. Launched as a Element of the 3G CDMA (Code Division Multiple Access) digital network know-how, EV-DO gives quick data rates, thus improving the mobile connectivity and World wide web access speeds for smartphone users and people utilizing data cards on laptops and other devices. Its key reason would be to aid superior-pace World-wide-web on mobile devices, thereby serving to end users stream films, browse the online, obtain apps, and use their devices for other internet-linked duties on the run.
