Embodiment Construction

[0025] The basic idea of ​​the present invention is: the user terminal judges whether it is necessary to change the setting of the initial network selection according to the currently detected time information or the change of the WLAN related information, and if so, refreshes the initial network selection set in the current user terminal, when When it needs to be used, directly use the refreshed initial network selection to try to access; otherwise, do not refresh, and when it needs to be used, still use the set initial network selection, so as to ensure that the user terminal is in the current WLAN service area When a change occurs, update its own initial network selection in a timely manner, that is, the information of the mobile communication operating network with the highest priority access, and then access the optimal mobile communication operating network at the fastest speed.

[0026] Here, the time information refers to the valid time corresponding to the set initial ...

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...
