Abstract

Operators require new features and capabilities for current wireless systems to support increasing demand of high speed data services. Packet Control Unit (PCU) is a new node in a Base Station Controller (BSC) to provide high speed packet data service. The major responsibilities of PCU are as follows: segmentation/assembly of Point-to-Point (PPP) frames to/from ACN stream, session management, flow control and congestion control, DCR PLICF, and short data burst management for dormant calls. In this paper, Medium Access Control (MAC) layer in the PCU is analyzed for cdma2000 wireless network. With respect to QoS functionality in MAC layer, session setup delay is observed. In the simulation, it is assumed that the maximum transmission rate for forward link is 153.6 kbps while the transmission rate for reverse link is fixed to 9.6 kbps.
