Claim of US Patent No. 9,392,624

1. A method of facilitating wireless communication, comprising:
receiving a message from a mobile station currently being served by a serving base station in a CDMA 2000 network, the message
comprising a service option field containing a plurality of radio configurations supported by the mobile station, wherein
the plurality of radio configurations include options 8 and 11 that are not compatible with radio control capabilities supported
by a legacy network, wherein an indication of a radio configuration, among the plurality of the radio configurations, is selectively
recognized by the serving base station depending on whether the serving base station supports the radio configuration;

establishing a radio link between the mobile station and the serving base station, by using the indicated radio configuration
if the serving base station supports the radio configuration and otherwise establishing the radio link by using a radio configuration
supported by the serving base station; and

communicating, during a handoff operation for a possible handoff of the mobile station to a target base station, wherein the
target base station implements a protocol revision that is different from that of the serving base station, the supported
radio configurations in a handoff message to the target base station.
