Channel scanning method and apparatus for use in dual-mode mobile station
First Claim
1. A dual-mode mobile station for use in a convergence service system including a mobile communication network and an unlicensed wireless network, the dual-mode mobile station comprising:
- a mobile communication interface wirelessly connected to the mobile communication network;
an unlicensed wireless interface wirelessly connected to the unlicensed wireless network based on Internet protocol;
a storage that stores at least one element of a priority channel information and a scan period information for searching for a wireless local area network access point (WLAN AP) of the unlicensed wireless network; and
a central processor that alternately scans all channels and one or more priority channels in order to search for the wireless local area network access point according to the scan period information stored in the storage.

Abstract
A channel scanning method and apparatus for use in a dual-mode mobile station are provided. A mobile communication interface is wirelessly connected to a mobile communication network. An unlicensed wireless interface is wirelessly connected to an unlicensed wireless network and based on Internet protocol. A storage stores at least one element of priority channel information and scan period information for searching for a wireless local area network access point (WLAN AP) of the unlicensed wireless network. A central processor alternately scans all channels and priority channels in order to search for the WLAN AP according to the scan period information stored in the storage. The number of channels to be scanned can be minimized by alternately scanning channels, and consumption of electricity can be minimized by reducing the number of scans during a given time in a region where the unlicensed wireless network is not configured.

8. A method for scanning channels in a mobile station of a convergence service system including a mobile communication network and an unlicensed wireless network, comprising the steps of:
-
setting at least one element of a basic channel information input from a user and a priority channel information based on basic channel information initially set in a wireless local area network access point through which the unlicensed wireless network is accessed; alternately selecting and scanning at least one element of the priority channel information and an all-channel information according to a scan period information for searching for the wireless local area network access point in a state in which the mobile communication network has been accessed; and scanning at least one element of the all-channel information and the priority channel information selected when the wireless local area network access point is not found after a predetermined number of periods using the at least one element of the priority channel information and the all-channel information. - View Dependent Claims (9, 10, 11)
