抄録

CDMA is considered a suitable access control for wireless multimedia communication systems. In this paper, we present an access scheme for packet-typed wireless networks, called PRMA/URN (Packet Reservation Multiple Access/URN) for the CDMA environment. This protocol combines URN algorithm with PRMA, instead of slotted-ALOHA. Also, we introduce enhanced access control into PRMA/URN for effective transmission of multimedia information, I.e. voice and data information. The enhanced access control has two characteristics. First, voice mobile terminals have priority in the initial access. Second, data mobile terminals can transmit packets continuously if necessary. We carry out the performance comparisons for CDMA environments between PRMA, PRMA/URN and PRMA/URN with enhanced access control, and show numerically the effectiveness of PRMA/URN with enhanced access control.
