Patent ID: 7672272

Claim:
A method of adapting circuit-switched payload transport between a mobile station and an unlicensed-radio access network controller utilizing a packet-based transmission protocol, said method comprising the steps of: receiving in the mobile station, a channel activation message from the access network controller, said channel activation message including a minimum acceptable sample size of the circuit-switched payload to be included in each packet; determining whether the mobile station is capable of supporting communications utilizing the minimum acceptable sample size; if the mobile station is capable of supporting communications utilizing the minimum acceptable sample size, sending an acknowledgment message from the mobile station to the access network controller accepting the minimum acceptable sample size as the sample size to be utilized by the controller for transmissions to the mobile station; and if the mobile station is not capable of supporting communications utilizing the minimum acceptable sample size, selecting a larger sample size which the mobile station is capable of supporting; and sending an acknowledgment message from the mobile station to the access network controller specifying the selected larger sample size as the sample size to be utilized by the controller for transmissions to the mobile station.
