Patent ID: 8554215

Claim:
In a micro-type base station configured to operate in a wireless communication system, and further configured to support data connections of both a first protocol type and a second protocol type with access terminals operating in the wireless communication system, a method comprising: receiving an access request from an access terminal to initiate a communication session using a data connection of the second protocol type, wherein the access request includes a particular identifier that is one given type of a plurality of types of identifiers that are each uniquely associated with the access terminal, and wherein the second protocol type has no specification to include identifiers of the given type in access requests for data connections of the second protocol type; and establishing a data communication session of the second protocol type with the access terminal based at least in part on the particular identifier included in the access request, wherein the micro-type base is a femtocell station configured to operate according to a CDMA family of protocols, including at least 1X-RTT and EVDO, wherein the first protocol type is 1X-RTT, the second protocol type is EVDO, and the particular identifier is an IMSI included in the received access request, and wherein establishing the data communication session of the second protocol type with the access terminal based at least in part on the particular identifier included in the access request comprises associating the IMSI included in the received access request with data transmissions between the femtocell and a Packet Data Serving Node in the wireless communication system.
