Abstract

The invention relates to a communication technology, solves the problem that most of the traditional methods for vertical switching among wireless heterogeneous networks do not focus on the state of a user terminal, and provides a vertical switching method of the wireless heterogeneous networks and a user terminal. A technical scheme disclosed by the invention is summarized as follows: in the vertical switching method of the wireless heterogeneous networks, three standby modes, including a motion pattern, a normal pattern and a low electric quantity mode, of the user terminal are defined at first, then, the user terminal determines whether to trigger network switching according to a communication condition, and after judging that the network switching needs to be triggered, the user terminal selects to access a universal mobile telecommunication system (UMTS) or a selected wireless local area network (WLAN) according to the standby modes or a communication mode. The vertical switching method disclosed by the invention has the beneficial effects of guaranteeing the user terminal to access the most appropriate network accurately and efficiency under a UMTS and WLAN multi-coverage environment and being applicable to a mobile terminal.

Description

technical field [0001] The present invention relates to communication technology, in particular to vertical switching technology between wireless heterogeneous networks accessed by user terminal equipment. Background technique [0002] In recent years, mobile communication and broadband wireless access technology have developed rapidly, and its development goal is to enable anyone to communicate with anyone in any form at any time. To achieve this goal, it is necessary to integrate existing wireless networks and new network access technologies that may arise in the future to jointly provide user terminals with ubiquitous collaborative heterogeneous access networks. Existing wireless networks mainly include wide-area cellular mobile communication networks (typical cellular systems such as 2G / 3G / B3G, etc.), and wireless broadband access technologies represented by IEEE802 series standards, such as Wireless Personal Area Networks (WPAN, Wireless Personal Area Network), Wireles...
