摘要： A system and method is provided for fast call set-up in a wireless communication system. A base station sets up a call from a mobile station by sending null frames to the mobile station on a forward traffic channel instead of sending a base station acknowledgement order. The mobile station sends a traffic channel preamble to the base station on a reverse traffic channel instead of sending a mobile station acknowledgment order. The fast call set-up procedure of the present invention reduces the call set-up time from approximately two (2) to three (3) seconds to approximately two hundred milliseconds (200 msec) to three hundred milliseconds (300 msec).

摘要： A system for providing parallel, concurrent transmission of multiple DRC elements is disclosed. An assignment element assigns, for each access terminal in an access network, two DRC-related parameters. A first parameter is assigned to uniquely identify a given access terminal. A second parameter is assigned to identify DRC traffic for that access terminal. An allocation message, such as a traffic channel allocation message, is modified to communicate the parameters from the access network to an access terminal. The access terminal processes its DRC traffic with both parameters, enabling the access network to identify its transmissions regardless of time multiplexing.
