In General packet radio service (GPRS), the RLC-MAC protocol doesn't allow the network to have any knowledge of the Uplink bandwidth required by the mobile station. In a GPRS network, the remote location of the Packet Controller Unit (PCU) causes a round trip delay between the PCU and the BTS. This results in the network allocating inappropriate amount of Uplink bandwidth to the mobile. However, by implementing a software algorithm at the PCU to monitor trends in the quantity of uplink data in previous uplink packet transfers by the mobile, the PCU can efficiently allocate uplink resources in the future. Additionally, in a PCCCH enabled cell, the network has the capability to identify that the MS needs to transmit upper layer control message and allocate lesser uplink bandwidth (2 blocks) to such mobiles. In this way uplink bandwidth can be used efficiently in the network.
