Abstract
A system and method for the wireless transmission of data packets in a code division multiple access communication system wherein one of the code division multiple access channels (PRCH) is used in a time-shared fashion for the transmission of the data packets from several transmitting stations (MSy, MSz) to a receiving station (BS). PA1 A request is sent from a transmitting station (MSy) to the corresponding receiving station (BS) of the communication system indicating the destination address to which data packet(s) are to be routed. PA1 Then, registering the transmitting station (MSy) and assigning an unique virtual connection identifier (VCIy) to it. PA1 Next, the transmitting station (MSy) is attached to the code division multiple access channel (PRCH) used for the transmission of data packets. PA1 Then, listening to the downlink of the code division multiple access channel (PRCH) used for the transmission of data packets until the corresponding receiving station (BS) broadcasts that it will be "idle" such that a random access to the code division multiple access channel (PRCH) used for the transmission of data packets is allowed in the next frame. PA1 Next, the transnmission p…
