Apparatus and method for transmitting wireless LAN information in mobile communication network for wireless LAN interworking
First Claim
1. A method for transmitting wireless local area network (WLAN) information in a mobile communication network for WLAN-interworking, the method comprising the steps of:
- determining whether a WLAN area present in a cell has both a radius characteristic and a directional characteristic relative to a base station (node B) provided in the cell;
establishing a WLAN threshold value for determining if the WLAN area is present in the cell, and a measurement period in system information, the WLAN threshold value allowing a terminal to determine if the result of a common pilot channel measurement is sufficient, if the WLAN area has both the radius characteristic and the directional characteristic;
broadcasting the system information in the cell; and
transmitting the common pilot channel, which indicates that the WLAN area is present at the terminal in the cell, in a predetermined direction with predetermined transmission power to cover the WLAN area by using beam forming.

Abstract
An apparatus and a method are provided for transmitting wireless local area network (WLAN) information in a mobile communication network for WLAN-interworking. The method includes the steps of setting a WLAN threshold value, which is used for determining if a WLAN area is present in a cell, and a measurement period in system information, broadcasting the system information in the cell, and transmitting a common pilot channel, which indicates that the WLAN area is present in the cell, in a predetermined direction with predetermined transmission power to cover the WLAN area by using beam forming.

6. A method for receiving wireless local area network (WLAN) information in a mobile communication network for WLAN-interworking, the method comprising the steps of:
-
determining whether a WLAN area present in a cell has both a radius characteristic and a directional characteristic relative to a base station (node B) provided in the cell; receiving system information broadcasted in a cell and determining whether the system information includes a WLAN threshold value for determining if the WLAN area is present in the cell, as well as code information and a measurement period of a second common pilot channel, the WLAN threshold value allowing a terminal to determine if the result of a common pilot channel measurement is sufficient, if the WLAN area has both the radius characteristic and the direction characteristic; measuring a first common pilot channel and determining whether a measurement result of the first common pilot channel exceeds the WLAN threshold value if the system information includes the WLAN threshold value only; measuring the second common pilot channel and determining whether a measurement result of the second common pilot channel exceeds the WLAN threshold value if the system information includes all of the code information and the measurement period of the second pilot channel and the WLAN threshold value; and initiating a WLAN scan if the measurement result of the first common pilot channel or the second common pilot channel exceeds the WLAN threshold value. - View Dependent Claims (7)
