Techniques for facilitating wireless communication include receiving a message from a mobile station, the message comprising a service option field indicative of an advanced radio configuration capability of the mobile station and establishing a radio link between the mobile station and the serving base station, by using the indicated advanced radio configuration capability. In some implementations, in a CDMA2000 network, a Revision E compliant mobile station is able to operate in Revision E mode with a Revision E base station and a legacy mode with a legacy base station, without being affected by a handoff and without a need to modify bit length of the revision field in the paging response message from the mobile station.
