Abstract

Entering into roam state, user terminal of WLAN sets up and stores own initial network selection. The method includes steps: current user terminal of WLAN detects and obtains current information of time or WLAN associated information; based on the obtained time information or change state of LAN associated information, the user terminal of WLAN determines whether changing setting of initial network selection is needed; if yes, the user terminal of WLAN refreshes own stored initial network selection and hints the user; otherwise, the initial network selection is reserved. The invention makes user terminal of WLAN possible to select a suitable mobile communication network from multiple connected WLAN to access.

Description

technical field

[0001] The invention relates to network access technology, in particular to a method for maintaining initial network selection settings for a user terminal in a wireless local area network. Background technique

[0002] As users have higher and higher requirements on wireless access rates, a wireless local area network (WLAN, Wireless Local Area Network) emerges at the historic moment, which can provide high-speed wireless data access within a small range. Wireless local area network includes a variety of different technologies. A technical standard that is widely used at present is IEEE802.11b, which uses the 2.4GHz frequency band, and the maximum data transmission rate can reach 11Mbps. IEEE 802.11g and Bluetooth (Bluetooth) technology are also used in this frequency band. , Among them, the highest data transmission rate of 802.11g can reach 54Mbps. Other new technologies such as IEEE 802.11a and ETSI BRAN Hiperlan2 both use the 5GHz frequency band, and th...
