Abstract
Abstract A telecommunications system and method is disclosed for allowing a mobile station to determine whether or not to place a wireless call through an internet protocol (IP) based local area network (LAN) based upon broadcasted Quality of Service (QOS) information. The gatekeeper within the IP based LAN has access to the QOS information and periodically sends the QOS to the base station controller (BSC) functionality within the access node (AN) of the IP based LAN. The BSC functionality then transmits the QOS parameter on the System Information message via the base transceiver station (BTS) to the mobile stations served by the BTS. The mobile stations receive this QOS information and use this QOS information to decide upon a transport method to complete outgoing wireless calls.
