Abstract: A high rate packet data communication system and method are provided that can control a rate of a plurality of forward channels by transmitting/receiving data rate control (DRC) information over at least one DRC channel. In the system, at least one mobile station (MS) determines a transmission time of the DRC information such that a transmission period of the DRC information for each of the forward channels is equal, and sequentially transmits the DRC information repeatedly for the forward channels over at least one DRC channel for a predetermined number of slots. A base station (BS) determines a rate of a corresponding forward channel based on the DRC information received over at least one DRC channel.

Abstract: Provided is a method and apparatus in a mobile communication system, which can achieve efficient session negotiation when an Access Terminal (AT) and an Access Network Transceiver System (ANTS) of the mobile communication system have different parameters for a session setup therebetween. The method includes selecting a configuration attribute from among configuration attributes for session negotiation, determining if the AT and the session controller have assured to use an enhanced configuration request message for the selected configuration attribute, and if so, the AT transmits an enhanced configuration request message including an identifier of the selected configuration attribute without a list of attribute values that the AT wants to use for the selected configuration attribute to the session controller.
