Patent ID: 7266106

Claim:
A method of adapting payload transport between a mobile station and an unlicensed-radio access network controller utilizing the Real-Time Protocol (RTP), said method comprising the steps of: (a) establishing an ongoing session between the mobile station and the access network controller, wherein the mobile station and the access network controller utilize an assigned sample size of the payload to be included in each packet; (b) detecting by either the mobile station or the access network controller, a change in network performance related to the ongoing session (c) in response to the detected change in network performance, negotiating a new sample size between the access network controller and the mobile station, wherein, upon the access network controller detecting the change in network performance, the step of negotiating a new sample size includes the steps of: (c1) sending a message from the access network controller to the mobile station with a suggested sample size determined in response to the detected change in network performance, wherein the message is a URR MODIFY CHANNEL message that includes a sample size information element; and (c2) receiving an acknowledgment message from the mobile station to the access network controller accepting the suggested sample size, wherein the acknowledgment message is a URR MODIFY CHANNEL ACK message that includes the sample size information element; and (d) utilizing the new sample size by the mobile station and the access network controller for the ongoing session.
