METHOD FOR MANAGING SELECTIVE ACCESS TO A WIRELESS NETWORK IN A MOBILE TERMINAL AND AN APPARATUS FOR SAME
First Claim
1. A method of managing access to a wireless network in a wireless terminal, comprising:
- detecting wireless signals from one or more access points of the wireless network N−
1 (N>
=2) times at different points of time under a disconnected state in which an IP address is not assigned from the wireless network, and for each of the access points, storing strengths of the detected wireless signals in a detected order thereof;
detecting wireless signals from one or more access points of the wireless network once more (N-th detection), and determining which state the wireless terminal is in among predetermined states including at least a first state and a second state, based on numerical values derived from differences between a strength of each of all or part of the N-th detected wireless signals and one of the stored strengths, said one of the stored strengths and the strength of said each of all or part of the N-th detected wireless signals being about signals detected from same access point; and
conducting an operation selectively for connecting to the wireless data network or for displaying accessibility to the wireless network, according to the determined state.

Abstract
The present invention relates to a method and apparatus for managing access to a wireless data network in a wireless communication terminal. In a wireless communication terminal embodying the invention, wireless signal from at least one of access points of a wireless data network is firstly detected and the strength of the signal is saved. Then, signal strength is secondly detected from the at least one of access points and differences between the firstly-detected signal strengths and the secondly-detected ones are calculated for each of the at least one of access points. Based on whether or not the differences fall within a predetermined range, it is determined whether a wireless communication terminal is in motion or not. If the terminal is in motion, accessing to a wireless data network is prohibited or a sign indicating that access to a wireless data network is impossible is displayed even though access points accessible are found. If the terminal is determined to be in abeyance, access to a wireless data network is attempted or a sign indicating that access is possible is displayed.
