| 1. A method for supporting, by a Mobile Station (MS), a handoff between Base Stations (BSs) supporting different operation
profiles in a Broadband Wireless Access (BWA) communication system including a serving BS and at least one neighbor BS adjacent
to the serving BS, the serving BS currently providing a service to the MS, the method comprising:
receiving, by the serving BS, physical layer information for communication from the at least one neighbor BS;
combining, by the serving BS, the received physical layer information of the at least one neighbor BS;
inserting, by the serving BS, the physical layer information into a PHY Profile Indicator (ID) field of an advertisement message,
the PHY Profile ID field indicating an operation profile for the at least one neighbor BS;
transmitting, by the serving BS, the advertisement message to the MS;
receiving, by the MS, the advertisement message; and
performing the handoff according to the physical layer information of the at least one neighbor BS included in the advertisement
message by performing a channel synchronization process, and without performing an operation profile synchronization process
according to a cell selection process.
