Method and apparatus for switching mobile station between autonomous and scheduled transmissions
First Claim
1. A method for operating a mobile station with a base station, comprising:
- when the mobile station is in an Autonomous mode of operation, autonomously transmitting data from the mobile station to the base station on a reverse access channel or reverse supplemental channel;
in response to receiving an acknowledgment indication from the base station, that comprises a reverse channel assignment message for the mobile station, switching the mobile station to a Scheduled mode of operation; and
transmitting data from the mobile station on an assigned reverse channel.

Abstract
Disclosed is a method for operating a moible station with a base station, as well as apparatus for performing this method. The method includes, when the mobile station is in an Autonomous mode of operation, autonomously transmitting from the mobile station to the base station of a reverse access channel or a reverse supplemental channel (Transition 3); in response to receiving an acknowledgement indication from the base station, that comprises a reverse channel assignment message for the mobile station, switching the mobile station to a Scheduled mode of operation (Transition 4) and transmitting data from the mobile station on an assigned reverse channel.

23. A method for operating a mobile station (MS) with a base station (BS) for transmitting data packets from the mobile station to the base station over a reverse supplemental channel (R-SCH), wherein there exist at least four R-SCH states and at least eight transitions between the R-SCH states, where the at least four R-SCH states comprise a R-SCH initialization state, a R-SCH autonomous state, a R-SCH scheduled state, and a R-SCH release state, comprising:
-
executing one of a plurality of techniques to initialize the R-SCH state, comprising one of, sending a modified Supplemental Channel Request Message (SCRM) to the BS, and receiving from the BS an acknowledgement as a modified Extended Supplemental Channel Assignment Message (ESCAM), where the modified SCRM comprises at least one of MS buffer status, transmit power, Quality of Service (QoS) level and a preferred mode of R-SCH operation, said preferred mode of R-SCH operation being one of an Autonomous mode or a Scheduled mode, and where the modified ESCAM comprises information to identify the MS;
sending a Supplemental Channel Request Message (SCRM) to the BS, and receiving from the BS an acknowledgement as a modified Extended Supplemental Channel Assignment Mini Message (ESCAMM), where the ESCAMM comprises the information to identify the MS; and
sending a request over a Reverse Enhanced Access Channel (R-EACH), where the request comprises parameters that specify at least the preferred mode of R-SCH operation. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
