Wireless mobile device and wireless network connection method thereof

Abstract

The invention relates to a wireless mobile device and a wireless network connection method thereof, which is used for switching a wireless local area network (WLAN) to a wireless wide area network (WWAN). In addition to a central processing unit and other functional modules, the wireless mobile device also comprises a first communication module, a first power source, a second communication module and a second power source, wherein the first power source and the second power source are respectively controlled by the central processing unit to supply power to the first communication module and the second communication module; a first communication interface of the central processing unit is connected to the first communication module and a second communication interface thereof is connected to the second communication module; the central processing unit detects whether the WLAN is available through the first communication module and is connected to the WLAN through the first communication module when the WLAN is available and is accordingly connected to the internet; and the central processing unit is connected to the WWAN through the second communication module when the WLAN is not available. The invention has the advantages of energy saving and capability of automatically switching wireless network modes.

Description

technical field [0001] The invention relates to the field of wireless network communication, in particular to a wireless mobile device and a wireless network connection method thereof. Background technique [0002] In general, wireless mobile devices (such as laptops) access the Internet wirelessly in two ways. One is Wireless Local Area Network (WLAN), which is mainly used for short-distance network connections. Connecting to the Internet generally costs less. At present, a wireless authentication (WIFI, Wireless Fidelity) communication module installed on a wireless mobile device is usually used for wireless network communication; the other is a wireless wide area network (Wireless Wide Area Network, WWAN). Access to the Internet is mainly through the base station of the mobile communication company, and the Internet can be accessed within the coverage of the wireless base station signal, but the cost is relatively high. Currently, GPRS communication modules, CDMA communic...

Problems solved by technology

[0003] In some cases, such as when the user enters the room, the signal of the wireless wide area network is often weak, and its communication equipment needs more power to obtain a better communication effect, which requires more battery energy consumption, and the room happens to be a wireless network. In an environment with a better LAN signal, the use of wireless LAN does not require too much energy consumption to obtain better communication results, and the network cost of wireless LAN is lower; however, in other cases, such as when there is no wireless LAN signal Or when the signal of the wireless LAN is weak and the signal of the wireless WAN is better, such as in an outdoor environment, the user has to use the wireless WAN for wireless network connection
