Abstract

Method and apparatus for detection and selection of Wireless Local Area Network (WLAN) service. A cellular network may provide an advertisement for a WLAN, such as in an overhead signaling message. The advertisement may identify the Access Point(s) by an Extended Service Set Identifier (ESSID). The remote station may then scan for the WLAN service automatically or manually.

Claims

1. In a wireless communication system, a method for identifying a Wireless Local Area Network comprising:

identifying WLAN availability; and

broadcasting a WLAN advertisement via a common communication channel.
